It is having an automatic conveyorized assembly line to cope up the requirements of bulk quantity. Correct selection of material and surface treatment gives a long durable life. Ever-Power offers these gearboxes with diameters of 25, 32, 45 mms, giving output torque up to 15 Nm. A variety of reduction ratios from 3.2 in single stage up to 625 in quadruplet stages are offered. With a proper R & D, the design is made to

Using miniature gears, Ever-Power has designed and built unique, high precision mini gearboxes that cannot be found anywhere else. Our miniature gearboxes are available in numerous configurations, including worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide custom micro gearboxes that are designed and built to meet your unique specifications.

Micro Gearbox Options

Gearboxes are also known as reducers, gear reducers, speed reducers, gear drives, and gearmotors. All terms can be used more or less interchangeably. Please note that the links for our small gear drives include information on the full range of frame sizes for that series or style.

Bevel Box Micro Gear Drive

Our bevel box miniature gear drives are application rated for the optimum balance of performance and cost. Torque can be balanced to meet your RPM and operating life requirements. Lightweight with low backlash performance (as little as 1°, with option of 1/2”).

Output torque: up to 7 oz.-inches

Low backlash: ≈1°, option of 1/2”

Rated for input speeds up to 2,000 RPM

Temperature range: -5° to 175°F (-20° to 79°C); optional to -40°F (-40°C)

Cross Axis Helical Miniature Gearbox

Ever-Power miniature cross axis helical gearboxes provide relatively high amounts of thrust in a compact package. They provide an output shaft at 90° from the input, and are available in gear ratios from 1:1 to 40:1. Lightweight but durable, with machined aluminum housings and hardened alloy steel gears.

High efficiency: up to 88% at 1,000 RPM

Low backlash: as low as ≤30 arc minutes

Rated for input speeds up to 4,000 RPM

“Left hand” models available

Miniature 2 Shaft Worm Gearbox

Our miniature 2 shaft worm gearmotors are engineered for ≤30 arc minutes of backlash or better. Also called “shaft to bore gearboxes,” these devices provide a single input shaft that protrudes from opposite sides of the housing; output is a keyed bore. Standard single- and double-end shafts are available and supplied with keys and retainer rings. An array of gear ratios and input sizes are available to meet your needs.

High efficiency: up to 86% at 1,000 RPM

Low backlash: ≤30 arc minutes or better

Available in ratios from 5:1 to 120:1

Rated for input speeds up to 3,000 RPM

Miniature 4 Shaft Worm Gearbox

Every miniature 4-shaft worm gearbox from Ever-Power features precision-machined hardened steel gears, solid aluminium housings, and permanent lubrication. They provide two input shafts on opposite sides of the frame, with two output shafts perpendicular to the input shafts. Our mini 4 shaft worm gear drives deliver high efficiency performance with low backlash.

High efficiency: up to 82% at 1,000 RPM

Low backlash: as little as ≈2°

Available with gear ratios from 1:1 to 32:1

Rated for input speeds up to 4,000 RPM

Miniature Flange Worm Gear Drive

These micro flange worm gearboxes produce an output at 90° from the input. They deliver superior performance in a wide variety applications and are built with small footprints, making them ideal for operations where space is limited. They offer high efficiency with low backlash.

Gear ratios from 6.66:1 to 80:1

High efficiency: up to 83% at 1,000 RPM

Low backlash: as low as ≤4°

Max. input speed: 3,000 PRM

DC motor option available

Miniature Inline Spur Gearbox

Specially engineered for encoder applications, Ever-Power micro inline spur gear drives are available in two frame sizes, and are rated for speeds up to 3,000 RPM. Aluminum  housings and stainless steel gears and shafts make these inline spur gearboxes tough and corrosion resistant, for your most demanding applications.

Output torque: up to 125 oz.-inches

Low backlash: as little as 15 arc minutes

Available with gear ratios from 4.96:1 to 3600:1

Optional synchro cleats available

Compact Wormwheel Gearbox

These miniature right angle worm gear reducers deliver superior performance with high efficiency, and feature rugged construction for challenging power transfer operations. Available in three gear ratios (5:1, 10:1, 20:1), our compact worm gearboxes are built in extremely compact footprints for applications where space is limited.

90° output angle

Gear ratios: 5:1, 10:1, and 20:1

Up to 12.5 inch-lbs. of output torque

Max. input speed: 3,000 RPM

Compact footprint: 1.5” x 1.5” x 1.08”

Custom Miniature Gearbox

Ever-Power can engineer and manufacture a custom miniature gearbox to meet your unique specifications. We can produce custom micro gearboxes in any configuration your application requires, with output torque levels as high as 900Nm. We can work from your gearbox designs, reverse engineer an existing unit, or help you develop an all-new design that delivers the performance you need.
