The EPW Double Shaft Planetary Gearbox series represents a pinnacle in \u043f\u043b\u0430\u043d\u0435\u0442\u0430\u0440\u043d\u0430\u044f \u043a\u043e\u0440\u043e\u0431\u043a\u0430 \u043f\u0435\u0440\u0435\u0434\u0430\u0447<\/strong> engineering, specifically tailored to address the dynamic challenges found in industrial \u0446\u0435\u043f\u044c<\/strong> drive integrations. Unlike standard inline gearboxes that rely solely on face-mounting, the EPW series distinguishes itself with a robust, integrated foot-mounted housing. This architectural feature is critical for the heavy manufacturing sectors of South Korea, from the automated logistics hubs of Incheon to the agricultural machinery manufacturers in Daegu. In a \u0446\u0435\u043f\u044c<\/strong> transmission system, the sprocket engagement creates a phenomenon known as the “polygon effect,” which generates pulsating shock loads and significant radial forces that attempt to twist the gearbox off its axis. The EPW’s wide, foot-mounted base anchors the unit firmly to the machine frame, effectively neutralizing these forces and ensuring that the output shaft remains perfectly aligned with the driven equipment. This stability is paramount for preventing \u0446\u0435\u043f\u044c<\/strong> misalignment, reducing wear on sprockets, and minimizing the risk of costly downtime in continuous production environments.<\/p>\n \u00a0 Furthermore, the “Double Shaft” configuration\u2014featuring a solid input shaft and a solid output shaft\u2014offers unparalleled versatility for system designers. This design allows the \u043f\u043b\u0430\u043d\u0435\u0442\u0430\u0440\u043d\u044b\u0439 \u0440\u0435\u0434\u0443\u043a\u0442\u043e\u0440 \u043f\u043e\u0432\u044b\u0448\u0435\u043d\u043d\u043e\u0439 \u043f\u0440\u043e\u0447\u043d\u043e\u0441\u0442\u0438<\/strong><\/a> to be decoupled from the prime mover, enabling the input to be driven via a belt pulley, flexible coupling, or a primary \u0446\u0435\u043f\u044c<\/strong> loop from a remotely mounted motor. This separation is highly advantageous in harsh operating conditions where the motor must be protected from heat, moisture, or vibration. Internally, the EPW series utilizes precision-ground 20CrMnTi alloy steel gears, heat-treated to HRC 58-62, to achieve high torque density in a compact footprint. With available \u043f\u043b\u0430\u043d\u0435\u0442\u0430\u0440\u043d\u044b\u0439 \u0440\u0435\u0434\u0443\u043a\u0442\u043e\u0440 \u0441 \u043f\u0435\u0440\u0435\u0434\u0430\u0442\u043e\u0447\u043d\u044b\u043c \u043e\u0442\u043d\u043e\u0448\u0435\u043d\u0438\u0435\u043c<\/strong> options ranging from 3:1 to 100:1, engineers can precisely match the gearbox output speed to the linear velocity requirements of their conveyor \u0446\u0435\u043f\u0438<\/strong>. Whether driving a slow-moving bucket elevator or a high-speed sorting line, the EPW series delivers consistent, high-efficiency power transmission (up to 97%) that meets the rigorous standards of modern Korean industry.<\/p>\n<\/div>\n Selecting the correct \u043f\u043b\u0430\u043d\u0435\u0442\u0430\u0440\u043d\u044b\u0439 \u0440\u0435\u0434\u0443\u043a\u0442\u043e\u0440<\/strong> for a \u0446\u0435\u043f\u044c<\/strong>-driven application requires a comprehensive analysis of mechanical loads, speed requirements, and dimensional constraints. The EPW series is engineered to provide a broad spectrum of performance capabilities, ensuring a perfect fit for applications ranging from light automation to heavy material handling. The table below details the specifications for our core models, including the compact EPW-40 and EPW-60, up to the robust EPW-160. A critical parameter to consider is the “Max Radial Load.” Since \u0446\u0435\u043f\u044c<\/strong> sprockets are typically mounted directly onto the solid output shaft, the gearbox bearings must support the tension of the \u0446\u0435\u043f\u044c<\/strong> without deflection. The EPW series features reinforced tapered roller bearings to maximize this load-bearing capacity. Additionally, the low backlash (under 5 arcmin for precision models) ensures that the \u0446\u0435\u043f\u044c<\/strong> movement is smooth and accurate, which is essential for indexing conveyors and positioning systems. We recommend using these figures as a baseline and consulting with our engineering team to verify the service factor for your specific duty cycle.<\/p>\n \u041f\u0440\u0438\u043c\u0435\u0447\u0430\u043d\u0438\u0435 \u043f\u043e \u043d\u0430\u0441\u0442\u0440\u043e\u0439\u043a\u0435:<\/strong> While our standard EPW models cover a wide range of needs, we understand that industrial retrofits often require unique dimensions. If you need specific foot mounting hole patterns to match an existing gearbox, or extended shaft lengths for dual-strand \u0446\u0435\u043f\u044c<\/strong> sprockets, please contact Ever-Power. We specialize in providing “Replacement of” solutions for major brands, ensuring a seamless drop-in fit for your machinery without extensive modifications.<\/p>\n<\/div>\n<\/div>\n One of the inherent challenges in designing \u0446\u0435\u043f\u044c<\/strong> drives is managing the “polygon effect” or chordal action. As the \u0446\u0435\u043f\u044c<\/strong> links engage and disengage with the sprocket teeth, the effective pitch radius oscillates, causing the chain speed to pulsate and introducing cyclical shock loads into the drive system. In a standard flange-mounted gearbox, these vibrations can leverage the mounting bolts, leading to gradual loosening or even fatigue failure of the housing face. The EPW series solves this with its dedicated foot-mounted design. By securing the gearbox to the machine bed with a wide, stable footprint, the EPW unit effectively dampens these vibrations and resists the overturning moments generated by the \u0446\u0435\u043f\u044c<\/strong> tension. This rigidity ensures that the alignment between the driving and driven sprockets remains constant, significantly extending the wear life of the \u0446\u0435\u043f\u044c<\/strong> and reducing the noise levels in the facility. For high-precision applications, such as indexing tables or automated assembly lines, this stability is crucial for maintaining positional accuracy.<\/p>\n The EPW’s double shaft configuration is a game-changer for layout flexibility. In many industrial environments, space is at a premium, and positioning the motor directly in line with the gearbox is not always feasible. The solid input shaft of the EPW series allows for “offset” driving arrangements. Engineers can mount the gearbox in the optimal position for the output \u0446\u0435\u043f\u044c<\/strong> drive, and then connect the input shaft to the motor using a belt, a secondary \u0446\u0435\u043f\u044c<\/strong>, or a cardan shaft. This allows the motor to be placed in a more accessible location for maintenance, or tucked away to reduce the overall machine footprint. Furthermore, the solid input shaft is supported by heavy-duty bearings capable of handling the side loads from a primary drive belt\u2014a capability that many hollow-input gearboxes lack. This makes the EPW series an ideal candidate for line-shaft conveyor systems where a single motor drives multiple gearboxes in series, ensuring synchronized movement across long distances.<\/p>\n<\/div>\n The robust design of the EPW Double Shaft Planetary Gearbox has made it a preferred choice across South Korea’s diverse industrial landscape. In the agricultural sector, particularly in the rice and ginseng fields of Jeolla-do, machinery needs to operate reliably in muddy and dusty conditions. The EPW series drives the track \u0446\u0435\u043f\u0438<\/strong> and harvesting mechanisms of combine harvesters and tractors. Its sealed housing (IP65) prevents the ingress of soil and water, while the high torque capacity handles the resistance of heavy, wet soil. The foot-mounted design allows for secure attachment to the vehicle chassis, withstanding the jolts and vibrations of uneven terrain. The availability of high reduction ratios allows these machines to move at the slow, controlled speeds necessary for precision harvesting, ensuring maximum yield for farmers.<\/p>\n \n<\/div>\n In the heavy manufacturing hubs of Ulsan and Busan, the EPW series is integral to automotive assembly lines and shipbuilding logistics. Overhead power-and-free conveyor systems, which utilize heavy steel link \u0446\u0435\u043f\u0438<\/strong> to transport car bodies and engine blocks, rely on the EPW \u043f\u043b\u0430\u043d\u0435\u0442\u0430\u0440\u043d\u044b\u0439 \u0440\u0435\u0434\u0443\u043a\u0442\u043e\u0440 \u043f\u043e\u0432\u044b\u0448\u0435\u043d\u043d\u043e\u0439 \u043f\u0440\u043e\u0447\u043d\u043e\u0441\u0442\u0438<\/strong> for their motive power. The low backlash of the gearbox ensures that the conveyor stops at precise locations for robotic welding or assembly tasks. Additionally, in the bustling ports, automated stacking cranes and bulk material handling conveyors use the EPW to drive drag chains that move coal, grain, and ore. The gearbox’s ability to handle high radial loads on the output shaft means it can be coupled directly to the head sprocket of these massive conveyors, simplifying the drivetrain and reducing maintenance requirements compared to traditional hydraulic drives.<\/p>\n<\/div>\n To achieve peak performance and longevity, a \u043f\u043b\u0430\u043d\u0435\u0442\u0430\u0440\u043d\u0430\u044f \u043a\u043e\u0440\u043e\u0431\u043a\u0430 \u043f\u0435\u0440\u0435\u0434\u0430\u0447<\/strong> must be paired with high-quality drivetrain components.
