\u2605 The Only Right-Angle Series in the Korea Ever-Power Range Rated for Hi Radial Load<\/div>\n

EP-ABR, EP-ADR, and EP-AER all deliver standard output shaft radial load capacity at 90 degrees. EP-AFR is the sole right-angle series in the Korea Ever-Power precision planetary gearbox range with an enlarged diameter high-rigidity output shaft<\/strong> \u2014 the same structural property that distinguishes the EP-AF inline series<\/a> from EP-AB, now applied to a right-angle output configuration.<\/p>\n<\/div>\n

\u0e40\u0e14\u0e2d\u0e30 EP-AFR series right-angle high-rigidity planetary gearbox<\/strong> is the product specified when a machine design simultaneously requires a 90-degree direction change<\/strong> between the motor and the load, and direct shaft-end mounting<\/strong> of a gear, pulley, sprocket, or cam that imposes radial force on the output shaft. Where the EP-ABR right-angle series<\/a> uses a standard-diameter shaft suitable for coupling-connected loads, EP-AFR’s enlarged shaft handles the combined bending and torsion loading of direct-mounted transmission components at the right-angle output \u2014 without a separate bearing housing to carry the radial load.<\/p>\n

All P0\/P1\/P2 backlash grades, the complete i=3\u201310 single-stage range, and all 17 two-stage ratios from i=12 to i=100 are available across all eleven EP-AFR frames. The EP-AFXR variant<\/strong> provides the same high-rigidity right-angle specification up to 1,200 N\u00b7m in ten frame sizes (no AFXR220).<\/p>\n

<\/p>\n

\n

The difference between EP-ABR and EP-AFR is the output shaft structural capacity. When the right-angle output shaft transmits only torque to a coupling-connected load, the standard shaft of EP-ABR is the correct and cost-appropriate specification. When the right-angle output shaft must simultaneously carry torque and radial force<\/strong> because a transmission component is mounted directly on the shaft end, EP-AFR’s enlarged shaft is the mechanically correct choice.<\/p>\n

\n

\u2460 Right-Angle Belt Drive \u2014 Tension Creates Radial Force at 90\u00b0<\/strong><\/p>\n

A timing belt pulley mounted on the EP-AFR right-angle output shaft generates belt tension as a radial force \u2014 at 90 degrees to the motor input axis. Packaging machines, labelling units, and printing register drives where the motor is perpendicular to the belt-driven axis use EP-AFR for this exact layout. The enlarged shaft resists the bending moment from belt tension at the right-angle output without deflection that would misalign the pulley and degrade belt-mesh accuracy.<\/p>\n<\/div>\n

\n

\u2461 Right-Angle Open Gear Pair \u2014 Mesh Force in Perpendicular Plane<\/strong><\/p>\n

When a spur or helical gear is mounted directly on the EP-AFR right-angle output shaft as part of an open gear pair, the gear mesh separating force acts in a plane perpendicular to the motor input axis. EP-AFR’s enlarged shaft carries this radial mesh force at the 90-degree output without a separate outboard bearing housing \u2014 eliminating a component that would otherwise be required to protect the standard output shaft of EP-ABR from premature bearing fatigue.<\/p>\n<\/div>\n

\n

\u2462 Right-Angle Sprocket and Cam Drives \u2014 Offset Load at 90\u00b0<\/strong><\/p>\n

Chain sprockets and eccentric cams mounted on the EP-AFR right-angle output shaft impose chain tension and eccentric mass bending moments at the 90-degree output. For Korean automated transport conveyors where the motor is positioned perpendicular to the conveyor chain axis, EP-AFR provides the right-angle direction change and the shaft structural capacity to carry the chain tension as a radial load \u2014 simultaneously, in one unit.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

EP-AFR vs EP-AF \u2014 Right-Angle vs Inline, Same High-Rigidity Shaft<\/h2>\n

EP-AFR and EP-AF are the right-angle and inline versions of the same high-rigidity shaft product concept. The output shaft diameter, the radial load capacity, the P0\/P1\/P2 backlash grades, and the complete ratio set are the same across both series. The single structural difference is the output direction. Choose EP-AF when the motor and load can be arranged coaxially. Choose EP-AFR when machine layout requires the motor axis to be perpendicular to the load axis.<\/p>\n

Applications \u2014 Right-Angle Direct Shaft Mounting in Korean Industry<\/h2>\n
\n
\n

Packaging Machine Corner Drives \u2014 Right-Angle Belt<\/h3>\n

Korean VFFS and HFFS packaging machine designs frequently locate the forming tube drive motor perpendicular to the film-pull belt axis, reducing machine height and allowing the motor to be positioned in the bottom cabinet. EP-AFR provides the 90-degree direction change from the perpendicular motor to the timing-belt-driven film-pull rollers \u2014 with the enlarged shaft carrying the belt tension radial force at the right-angle output. AFR075 and AFR100 P1 at i=5\u201325 cover the majority of Korean VFFS film-pull drive requirements. Pairs with precision CV drive shafts for dual-motor configurations requiring torque sharing between two AFR units.<\/p>\n<\/div>\n

\n

Printing Register Corner Gear Drive \u2014 P0 Right-Angle<\/h3>\n

Korean web-fed printing press register correction axes that use an open gear pair at 90 degrees to the servo motor \u2014 motor mounted across the press width, gear-driven register roller perpendicular \u2014 require a right-angle gearbox that carries the gear mesh separating force at the right-angle output shaft without deflection. EP-AFR075 P0 at i=10\u201332 serves Korean offset and flexographic press register axes, where the \u22641 arcmin P0 grade prevents backlash-induced colour register variation and the enlarged shaft maintains gear centre distance constancy through press-speed transients.<\/p>\n<\/div>\n

\n

Conveyor Corner Chain Drive \u2014 Right-Angle Sprocket<\/h3>\n

Korean automated assembly and logistics conveyor systems that change direction at a 90-degree corner use EP-AFR to drive the chain sprocket at the corner station \u2014 the servo motor is perpendicular to the conveyor chain axis, and the sprocket is mounted directly on the EP-AFR right-angle output shaft. Chain tension acts as a radial force on the output shaft; the enlarged shaft absorbs this without an outboard bearing housing at the corner station, reducing the conveyor corner unit’s axial depth and maintenance schedule.<\/p>\n<\/div>\n

\n

CNC Machine Tool Auxiliary Drives \u2014 Right-Angle at Tight Spaces<\/h3>\n

Korean machining centre chip conveyor drives and coolant pump drives positioned inside the machine column use EP-AFXR at small frame sizes (042, 060) where the motor must be perpendicular to the conveyor or pump shaft in a constrained machine cavity. The enlarged shaft carries the impeller or auger shaft radial load directly at the 90-degree right-angle output \u2014 eliminating the separate bracket-mounted bearing that would otherwise be required in the confined machine base space.<\/p>\n<\/div>\n

\n

Textile Corner Drives \u2014 Right-Angle Winding Roll<\/h3>\n

Korean knitting and weaving machine winding roll drives where the motor cannot be positioned behind the roll axis \u2014 machine structural members block the axial direction \u2014 use EP-AFR to place the motor alongside the machine frame perpendicular to the roll axis. The large winding roll is mounted directly on the AFR right-angle output shaft; its weight acts as a static radial force and its rotating mass adds a dynamic radial component. AFR140 P1 at i=20\u201350 covers Korean industrial textile winding machine torque requirements at this layout. Self-locking holding via worm gear reducers for vertical roll configurations.<\/p>\n<\/div>\n

\n

Agricultural Seeder Head \u2014 Right-Angle Direct Disc Mount<\/h3>\n

Korean precision agriculture seeder head drives where the seeder disc is mounted directly on a right-angle output shaft \u2014 the servo motor positioned along the boom frame, the seeder disc rotating perpendicular to it \u2014 use EP-AFXR for the compact right-angle high-rigidity drive. The disc weight and seed distribution reaction force act as a radial load on the right-angle shaft; the enlarged shaft absorbs this. Integration with agricultural bevel gearboxes for multi-row seeder configurations extends the single EP-AFXR output to multiple seeder heads.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
