Inline Planetary Gear Reducer Options
Gearboxes are known by many different brands, including gear drives, reducers, equipment reducers, velocity 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, lightweight spur gear inline planetary equipment reducers. These inline gearboxes could be direct 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 quickness: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings on all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, light-weight, low backlash gear drives are designed particularly for encoder applications. They employ a low minute of inertia at the shaft insight, 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 speeds up 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 limited, and are available either as a shaft insight or mounted 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 line of internal epicyclic servo reducers are extremely rugged and compact. These planetary gearboxes possess fully-machined housings (aluminum or steel), and are outfitted with ball bearings throughout. Our inline planetary equipment reducers offer flexible engine mounting options and can 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 durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor efficiency is important.
