Inline Planetary Gear Reducer Options
Gearboxes are known by many different titles, including gear drives, reducers, equipment reducers, speed reducers, and gearmotors. All terms can be used pretty much interchangeably when refering to inline planetary gear reducers.
Spur In-Line Gearboxes
Ever-Power offers a complete line of compact, light-weight spur equipment inline planetary equipment reducers. These inline gearboxes can be immediate installed to motors or used with shaft coupling. Ratios from 2:1 to 625:1 can be found, with torque values ranging 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, light-weight, low backlash gear drives were created specifically for encoder applications. They employ a low instant of inertia at the shaft input, and are rated for insight boosts 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.
Output torque: 1 oz.-inch
Backlash: 15 arc-minutes (in 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 gears and shafts
Ball bearings
Low Backlash Inline Taper Gearboxes
Our taper gearmotors are inline planetary equipment reducer boxes with backlash add up to or better than 8 arc/minute. These inline gearboxes are created for applications where space is bound, and are available either as a shaft insight 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 ideals from 1.14Nm to 12.7Nm
Epicyclic (Planetary) Servo Gearboxes
The Ever-Power type of internal epicyclic servo reducers are really rugged and compact. These planetary gearboxes have fully-machined housings (aluminium or steel), and are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible electric motor mounting options and may deliver result torques up to 380 Nm. Ratios from 3:1 to 36:1 can be found.

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