EP-SE417T3 三级履带驱动行星齿轮箱

这 EP-SE417T3 这是一款三级履带驱动行星齿轮箱，由一台转速为 3,000 rpm 的电机输入，可产生 220,000 N·m 的扭矩，传动比范围为 i=123–365。其旋转外壳直接将履带链轮安装在滚筒法兰上。该齿轮箱重达 1,450 kg，是本厂 SE 系列中最重的单体设备，安装时需要使用额定起重能力 ≥2,500 kg 的起重机。

The required tractive force scales approximately proportionally with machine weight. A 4,000-tonne machine on a 10° ramp requires approximately 4,000 × 9.81 × sin10° ÷ 2 drives ÷ 0.65 m sprocket = 538,000 N per drive tractive force. At a 750 mm sprocket radius: 538,000 × 0.75 = 403,500 N·m per drive before dynamic shock factor. With a 1.5× shock factor for large rope shovel tramming: 605,000 N·m per drive — well above EP-SE415T3's 110,000 N·m, requiring EP-SE417T3's 220,000 N·m with significant remaining safety margin. The machine class jump from 1,000–2,000 t (EP-SE415T3) to 2,000–5,000+ t (EP-SE417T3) directly produces the 100% torque increase in the drive specification, as tractive force scales with weight.

EP-SE417T3's 2,000 N·m brake is 67% higher than EP-SE415T3's 1,200 N·m — not 100% higher. The reason the brake does not need to double proportionally with torque is that i=365 (the maximum ratio for EP-SE417T3) is 70% higher than EP-SE415T3's i=215. At i=365, the 2,000 N·m brake produces 730,000 N·m effective output-side hold — 2.83× higher than EP-SE415T3's maximum of 258,000 N·m. The ratio increase more than compensates for the lower-than-proportional brake torque increase. Machines at the 2,000–5,000 tonne class that use EP-SE417T3 at high ratios (i=250–365) receive far more brake amplification than machines using EP-SE415T3 at i=200, even though the spring brake in absolute terms is only 67% larger.

EP-SE417T3's minimum ratio starts at i=123 — substantially higher than EP-SE415T3's i=81. At i=123, the output speed is approximately 24.4 rpm. At a 750 mm sprocket radius, this produces approximately 1.1 km/h maximum travel speed. The 2,000–5,000 tonne machines served by EP-SE417T3 do not travel faster than 1.0–1.5 km/h under any circumstances — the i=123 minimum ratio already represents the practical upper travel speed limit for this machine class. Starting the ratio range at i=123 rather than a lower value means all three stages can be configured to optimise for the i=123–365 operational range, with no wasted design effort on a fast-travel ratio band that the machine would never use. This contributes to the torque density achievable within the 1,450 kg housing.

i=365 is the highest ratio in the full SE series as covered on this site. At 3,000 rpm motor input, i=365 produces approximately 8.22 rpm sprocket output — 46% slower than EP-SE415T3's slowest output (13.95 rpm at i=215). The following numbers illustrate the engineering significance of this ratio for brake adequacy.

超大型步行式拉铲挖掘机和采矿铲

最大型的步行式拉铲挖掘机——臂长超过100米，铲斗有效载荷超过120立方米，总作业重量达5000至7000吨——在其产品系列的高端产品中均配备了履带式推进系统。对于这些机器，EP-SE417T3 型液压系统在工况i=200-280时可提供所需的推进力，使机器能够在矿井工作面上移动。在工况i=220时，2000牛·米的弹簧制动器可提供440000牛·米的机械保持力——当机器在不平整的矿井工作面上移动时，液压系统压力损失，该制动器可作为紧急位置保持装置。对于这些机器，在挖掘作业循环中，当推进液压回路在两次重新定位之间泄压时，弹簧制动器还可用作位置保持装置：当铲斗位于挖掘面时，机器必须防止在重力作用下沿工作面漂移。在 i=220 时，每驱动机械保持力为 440,000 N·m，弹簧制动器无需辅助平衡阀即可满足在 5–12° 的典型坡度上，重达数千吨的机械设备的制动要求。在 220,000 N·m 的额​​定驱动扭矩下，EP-SE417T3 能够满足这些极端机械设备在最陡峭的运行坡度下的牵引力需求，并具备所需的安全裕度。

大型隧道掘进机主驱动和推进系统

用于大型公路隧道、地铁隧道和大型水力发电隧道的18-22米孔径的大型隧道掘进机（TBM）在需要比EP-SE415T3更高的单轴推力时，可使用EP-SE417T3作为单个推进环单元。这些TBM产生的总推力为100,000-200,000+ kN，分布在多个推进环上。当单个推进环单元的载荷分析要求单轴推力超过110,000 N·m时，转速i=155-200的EP-SE417T3可提供所需的推力，并具有足够的安全裕度。在8-15 rpm的输出转速下，推进环的转速与大型TBM在硬岩中的掘进速度相匹配。

最大履带式起重机——2000吨以上起重能力

Crawler cranes with lift capacities above 2,000 tonnes — the very largest machines built for nuclear power plant reactor lifts, offshore jacket installation with 3,000+ tonne jacket weights, and large bridge girder placement — may have gross vehicle weights exceeding 1,500 tonnes in full counterweighted configuration. EP-SE417T3 serves the travel drives for these machines where machine weight at their steepest site gradients requires more than EP-SE415T3's 110,000 N·m per drive. The 2,000 N·m brake at i=180–250 provides the emergency position hold required by international crane safety standards for machines carrying loads exceeding 2,000 tonnes.

海上和海洋超重型履带式系统

The largest tracked transport platforms operating in marine and offshore environments — floating drydock transport systems, large subsea pipeline bundle deployment systems, and ultra-heavy yard transport platforms for FPSO module positioning — require EP-SE417T3 when total transported weight exceeds the capacity of EP-SE415T3 drives. These systems operate in salt water immersion, high-pressure wash environments, and corrosive coastal atmospheres. EP-SE417T3's dual-cone floating metal face seals sustain these conditions. Auxiliary cable winch and tensioner systems on these platforms use 蜗轮减速器 用于电缆卷筒上的自锁式负载固定装置。

超重型露天采矿机和采矿机械系统

Very large continuous surface miners at the upper end of the production class — machines above 1,500 tonnes cutting very hard rock formations at high production rates — require EP-SE417T3 for the track propel drives when machine weight combined with the cutting drum resistance forces produce tractive force demands exceeding EP-SE415T3's capability. At i=165–215, the surface miner advance speed of 5–10 rpm matches the cutting drum penetration rate for the hardest igneous formations. The 220,000 N·m drive torque provides the continuous tractive force needed for 100% duty cycle cutting advance in very hard rock.

超重型陆地开发和基础设施平台

用于大型水坝和水库建设、大规模沿海填海造地以及大型港口基础设施建设的巨型履带式填海和基础设施开发平台，在携带所有用于偏远地区作业的农具和耗材时，重量可能超过 2000 吨级。EP-SE417T3 为每驱动轮提供 220,000 N·m 的扭矩，以满足机器重量的需求。这些平台上的辅助地面作业工具和多输出农具驱动装置均采用 EP-SE417T3 驱动。 农业多输出齿轮箱 在独立的 PTO 电路上，与 EP-SE417T3 行走驱动装置无关。

电机选择、传动比、制动器——当日确认

EP-SE417T3's 3,000 rpm maximum applies here as with EP-SE415T3, and the motor displacement must be sized accordingly. Korea Ever-Power's same-day engineering response for EP-SE417T3 covers: motor displacement for your hydraulic circuit power at 3,000 rpm maximum; ratio from i=123–365 for your target travel speed; 2,000 N·m brake adequacy calculation including whether supplementary counterbalance valves are required for your machine weight and maximum gradient; and dimensional cross-reference against your incumbent drive. Provided in a single document, no charge, before any order commitment.

预组装并经制动验证，重量为 1,450 公斤

Korea Ever-Power provides EP-SE417T3 pre-assembled with matched large-displacement motor, overcenter valve, and pressure relief valve. The 2,000 N·m brake is function-verified before shipping — spring applied (drum locked), pilot applied at 15–30 bar (drum free within 1 second), oil filled. At 1,450 kg, on-machine brake commissioning with a 2,500 kg+ crane holding the unit would be operationally complex and time-critical. Korea Ever-Power's pre-shipment verification eliminates this risk entirely. The unit arrives ready for single crane lift and hydraulic line connection.

舞台级部件——1450公斤，已维修，未更换

Korea Ever-Power stocks all EP-SE417T3 internal components by stage: Stage 1, 2, and 3 sun gear and planet set assemblies; 2,000 N·m brake disc pack (complete with friction discs, separator plates, Belleville springs, O-ring kit); dual-cone floating face seal kits; taper bearing sets per bearing position; housing O-ring kits. At 1,450 kg, a complete 220,000 N·m track drive planetary gearbox replacement involves a 50–100 tonne crane and substantial site logistics. Component-level repair — replacing only the failed stage — is the only practical approach at this unit scale. Korea Ever-Power's stage-separated parts availability makes this feasible without returning the unit to factory. For a 220,000 N·m track drive planetary gearbox at 1,450 kg, establishing a pre-positioned spare parts set at the machine site or nearby workshop — including at minimum a seal kit, brake disc pack, and the most likely bearing set — eliminates the sourcing delay for any component that could need replacement within the warranty or extended service period.

韩国永力动力公司库存的标准传动比配置可在 7-14 天内交付。预组装电机组件：30-45 天。对于 3000 吨级的绳索铲或 18 米长的隧道掘进机而言，1450 公斤的重量和该扭矩等级下，任何计划外的驱动故障都将造成灾难性的生产损失。韩国永力动力公司可就此规模的大型车队洽谈框架供应条款、预留产能和寄售安排。请联系我们，提供您的设备车队详情和年产量，以便我们为您制定框架定价和应急响应计划。

-25°C 至 +90°C — 1,450 kg 热质量

EP-SE417T3 的工作温度范围为 -25°C 至 +90°C。其采用 1,450 kg 球墨铸铁外壳，热容量约为 1,450 × 500 J/(kg·K) = 725 kJ/°C，是本网站 SE 系列产品中热容量最高的，因此具有最长的热启动时间和最强的抗温度峰值能力。该型号效率高于 93%，扭矩容量为 220,000 N·m，满载时每千瓦产生的热量与 EP-SE415T3 相同，但绝对值更大。韩国 Ever-Power 可根据客户要求，免费提供高温环境和高负载循环应用的热评估。由于其热容量为 725 kJ/°C，1,450 kg 的外壳能够比任何更轻的 SE 系列产品更缓慢地吸收持续行驶过程中产生的热量，从而在间歇性高负载运行时提供天然的缓冲，防止温度峰值过高。对于标准-25°C至+90°C范围之外的操作，可提供Viton和低温密封化合物作为工厂选件。

We manufacture rope shovel propel systems for 3,500-tonne operating weight machines used in large copper and iron ore mines. Korea Ever-Power confirmed EP-SE417T3 at i=190 after calculating that at our steepest access ramp of 9° with 3,500 tonnes gross weight, the drive torque per unit with a 1.6× factor was approximately 175,000 N·m — requiring EP-SE417T3's 220,000 N·m for a 26% safety margin that our engineering specification requires. At i=190, the 2,000 N·m spring brake provides 380,000 N·m per drive mechanical hold — our type-approval requires 2.0× the maximum tramming torque from spring brake alone: at 380,000 N·m vs 175,000 N·m we achieve 2.17× per drive. Korea Ever-Power's pre-order engineering document was accepted by our certification body. The 1,450 kg installation required our site's 80-tonne crane — Korea Ever-Power provided the precise lifting attachment positions in the dimensional drawing. At 1,600 hours across six units in iron ore operation, zero EP-SE417T3 failures.

We supply main drive propel systems for large TBMs in the 17–21 metre bore diameter class. Our most recent 20-metre metro tunnel TBM uses 40 EP-SE417T3 units in the propel ring. The rock load analysis for our quartzite geology required 190,000 N·m per unit with a 1.15× load factor in the hardest sections — exceeding EP-SE415T3's 110,000 N·m and requiring EP-SE417T3. Korea Ever-Power specified i=162 for our advance rate target of 18.5 rpm at 3,000 rpm motor input. The 2,000 N·m brake at i=162 provides 324,000 N·m per unit hold — our TBM safety system requires immediate hold on pressure loss, and 324,000 N·m per unit with 40 drives gives enormous combined hold capacity. All 40 units installed without issues. At 1,850 hours through 4.2 km of tunnel (including mixed ground and fault zones), zero EP-SE417T3 failures. Korea Ever-Power's 7-14 day stock availability has been critical for our project schedule — we keep four units in reserve at the tunnel portal.

We operate specialised tracked sea-floor transport platforms for offshore infrastructure installation at water depths of 30–80 metres. Our largest platform system carries subsea manifold assemblies and pipeline end terminations weighing up to 2,400 tonnes combined system weight. Korea Ever-Power specified EP-SE417T3 at i=280 for our 12 propel drives. At i=280, the 2,000 N·m brake provides 560,000 N·m hold per unit — adequate for our maximum operational gradient of 4° on the seabed terrain with our largest payload. The dual-cone floating metal face seals have sustained continuous seawater immersion at depths of 45 metres without any seal failure or oil contamination in 2,300 hours of sea-floor operation across three project deployments. The 220,000 N·m capacity allows us to handle the highest-resistance seabed conditions (dense clay over rock bands) that occasionally exceed our EP-SE415T3 fleet's capability. Korea Ever-Power's same-day dimensional confirmation service was essential for our very tight project schedule on the first deployment — we had the technical documentation needed for our client's marine certification within 24 hours of enquiry.

问EP-SE417T3 的扭矩是 EP-SE415T3 的两倍——这对安装起重机和现场物流意味着什么？

EP-SE417T3 weighs approximately 1,450 kg — 600 kg (71%) more than EP-SE415T3's 850 kg. A 1,450 kg unit requires a certified crane rated at ≥2,500 kg, accounting for the safety factor on the crane rating. In practice, this typically means a 50–100 tonne telescopic crane or large industrial overhead crane at a manufacturing facility. Korea Ever-Power's dimensional drawing specifies the chain-attachment points on the drum housing for balanced lifting, and the unit hang angle for alignment into the spindle bore. Typical installation time with appropriate equipment is 14–16 hours per side with two experienced technicians. The installation complexity is the primary reason Korea Ever-Power strongly recommends pre-assembled and brake-verified units for EP-SE417T3 — having the motor and valves already fitted means the unit arrives as a complete, tested assembly and requires only a single crane lift and hydraulic line connection at the machine.

问弹簧制动器的扭矩为 2,000 N·m。这是否能为 3,000 吨重的机器在陡坡上提供足够的驻车抓地力？

For very large machines (above approximately 1,500 tonnes) on steep gradients (above approximately 10°), the 2,000 N·m spring brake alone may not provide the full required parking hold at minimum operating ratios. At i=123 (minimum ratio), the brake equivalent is 2,000 × 123 = 246,000 N·m per drive — holding approximately 258 tonnes at 15° per drive, or 516 tonnes combined. For a 3,000-tonne machine on a 10° gradient, the rolling force (combined both drives) is approximately 3,000,000 × 9.81 × sin10° = 5,107,000 N, requiring approximately 3,830,000 N·m combined torque at 750 mm radius. The spring brakes alone at i=123 provide 492,000 N·m — well short for this scenario. However, in actual operation, EP-SE417T3 would be specified at a high ratio (i=200–280) for most machine weights at this size, where brake equivalent is 400,000–560,000 N·m per drive. Additionally, the hydraulic motor circuit's counterbalance valves provide additional hold that acts in series with the spring brake. Korea Ever-Power calculates the combined spring brake plus counterbalance valve hold for your specific machine weight, ratio, and gradient, and advises whether the spring brake alone is adequate or counterbalance valve specification is required — same day, no charge. For machines at the boundary between spring-brake-only and combined-brake-valve adequacy, Korea Ever-Power provides the calculation for both conditions simultaneously, so the machine designer can determine whether a higher operating ratio within the i=123–365 range resolves the issue without adding counterbalance valve complexity to the hydraulic circuit.

问1450公斤三级泵装置的油量、首次换油程序和状态监测？

EP-SE417T3 contains approximately 40–55 litres of gear oil depending on ratio configuration and motor adapter — the highest oil volume in the SE series as presented here. The exact fill volume is on the Korea Ever-Power dimensional drawing for your specific configuration. First oil change at 150 operating hours: drain fully warm — with 40–55 litres, allow 30+ minutes complete drain time to evacuate all three stages' run-in particles. Refill with fresh API GL-5 VG 150 (below +15°C) or VG 220 (above +15°C). Subsequent changes: every 1,000 hours or annually. At this scale and unit value, ICP oil sampling at each 500-hour interval is strongly recommended. The large 40–55 litre oil reservoir means a small volume increase in elemental particle count can indicate a large absolute quantity of wear material — reference baseline elemental levels must be established at the 150-hour first change while the unit is new and known good. Korea Ever-Power provides reference elemental baseline ranges for EP-SE417T3 units in the startup documentation package. With 40–55 litres of oil, the drain and refill time at the first change and subsequent changes should be planned as a standalone maintenance activity requiring 1.5–2.0 hours per unit for the drain-warm-refill cycle alone, not including the crane time if the unit must be repositioned for port access. Korea Ever-Power’s dimensional drawing shows the port locations relative to the chassis bore orientation, allowing the maintenance team to confirm port access before scheduling the first-change maintenance window.

问EP-SE417T3 能否直接替代 220,000 N·m 级的 Rexroth GFT 或 Bonfiglioli 700C 型号？
