Gearboxes & Speed Reducers

Gearboxes are a fundamental component of many drive systems. With a wide range of designs and configurations available, gearboxes can be used to increase torque, reduce or increase speed, reverse rotation, or change the direction of the driveshaft. Gearboxes are often referred to as speed reducers, gear reducers, reducers, gear drives, and gearmotors.

Ondrives.US designs and manufactures high precision gearboxes in a range of sizes, from miniature to robust. We offer unique, compact, and lightweight gearboxes in ratios up to 3600:1, with output torque as high as 850Nm.

We offer the widest standard range of speed reducers, including wormwheel, crossed axis, right angle, counter rotating, spur gear, inline, rack and pinion, planetary motorized and miniature. We also offer customized gearboxes, with endless combinations of these configurations available. The possibilities are limited only by system requirements and designer imagination.

Wormwheel Gearboxes | Ondrives.USWormwheel Gearboxes

Ondrives.US compact right angle wormwheel speed reducers produce an output at 90° from the input. 10 space-saving frame sizes are available, with output torques as high as 420Nm.

 

Crossed Axis Gearboxes | Ondrives.USCrossed Axis Gearboxes

Our crossed axis gear drives produce an output at 90° from the input, and are built with anodized aluminum housings and hardened alloy steel input gears for durability in challenging applications. Available with gear ratios from 1:1 to 40:1 and torque values up to 62Nm.

 

Right Angle Bevel Gearboxes | Ondrives.USRight Angle Bevel Gearboxes

Our Bevel T right angle speed reducers feature a shaft that passes through both sides in the form of a “T”. This solid thru-shaft rotates at both ends simultaneously. Also available with a single output shaft. Available in ratios from 1:1 to 24:1.

 

Counter Rotating Bevel Gearboxes | Ondrives.USCounter Rotating Bevel Gearboxes

Our counter rotating T-style bevel gearboxes feature two output shaft on the same axis and an input shaft at 90° from both; the output shafts rotate in opposite directions.

 

Spur Gear Reducers | Ondrives.USSpur Gear Reducers

Also known as parallel shaft gearboxes, spur gear reducers provide an output that is parallel to the direction of the input shaft. Available in gear ratios from 2:1 to 7:1 with torque output up to 850Nm.

 

 

In-Line Gearboxes | Ondrives.USInline Gearboxes

Inline reducers provide an output that continues in the same direction and on the same plane as the input. We offer a wide range of inline reducers, including spur, Encoder, low-backlash taper, speed increasers, and more. Available in ratios up to 3600:1.

 

Rack and Pinion Actuators | Ondrives.USRack & Pinion Actuator Gearboxes

Ondrives.US’ rack and pinion actuator gear drives convert rotational motion into linear motion, or vice versa. Our compact designs provide short strokes from 10mm to 30mm.

 

Planetary & Motorized Gearboxes

Our motorized planetary reducers are small, inline devices designed for low backlash performance in speeds up to 3,000 RPM. Slim, compact footprints make them ideal for applications where space is limited.

 

Miniature Gearboxes | Ondrives.USMiniature Gearboxes

Many of our other gear reducer styles are available in miniature versions. These ultra-compact gearboxes are precision engineered for superior performance in tight spaces and small-scale applications.
