Inline Planetary Gear Reducer Options
Gearboxes are known by many different names, including equipment drives, reducers, gear reducers, velocity reducers, and gearmotors. All conditions can be used more or less interchangeably when refering to inline planetary equipment reducers.
Spur In-Line Gearboxes
Ever-Power offers a complete line of compact, light-weight spur equipment inline planetary gear reducers. These inline gearboxes can be immediate installed to motors or used in combination with shaft coupling. Ratios from 2:1 to 625:1 are available, with torque values which range from 0.13Nm to 90Nm.
Input rate: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings upon all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, lightweight, low backlash gear drives are designed particularly for encoder applications. They employ a low minute of inertia at the shaft input, and are rated for input speeds up to 3,000 RPM. Gear ratios from 4.96:1 to 3600:1 are available, in two frame sizes. Synchro cleats for our encoder gearboxes are available from stock.
Result torque: 1 oz.-inch
Backlash: 15 arc-minutes (at any ratio)
Ratios from 4.96:1 to 3600:1
Input boosts to 3,000 RPM
Diameter: 1-1/16” or 1-3/4”
Black anodized aluminum housing
303 stainless steel gears and shafts
Ball bearings
Low Backlash Inline Taper Gearboxes
Our taper gearmotors are inline planetary equipment reducer boxes with backlash equal to or better than 8 arc/minute. These inline gearboxes are created for applications where space is limited, and are obtainable either as a shaft input or installed to a 24V DC motor.
Low backlash: ≤8 arc/min. at input
Compact design
Shaft insight or with mounted motor
Ratios from 2:1 to 16:1
Output torque values from 1.14Nm to 12.7Nm
Epicyclic (Planetary) Servo Gearboxes
The Ever-Power line of internal epicyclic servo reducers are really rugged and compact. These planetary gearboxes have fully-machined housings (aluminum or steel), and are outfitted with ball bearings throughout. Our inline planetary equipment reducers offer flexible engine mounting options and may deliver output torques up to 380 Nm. Ratios from 3:1 to 36:1 can be found.

GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor efficiency is important.
