Gearboxes are drive parts that can enhance torque, reduce or increase speed, invert rotation, or alter the path or rotation of a driveshaft. Additional clearance, known as backlash, is built in to the gearbox components to prevent gears from binding, which causes overheating and may damage the teeth. A potential drawback of this, however, is that backlash can make it harder to accomplish accurate positioning.

Low backlash gearboxes have a modified design to lessen or eliminate backlash. This includes using gears and bearings with close tolerances and making sure parts are properly matched to reduce dimensional variations. Backlash is often limited by 30 arc-min, or only 4 arc-min, based on the design.
Low backlash gearboxes from Ondrives.US help improve positioning accuracy and minimize shock loads in reversing applications. We provide gearboxes and velocity reducers in a wide range of options which includes miniature and low backlash styles. Our engineers may also create personalized low backlash gearboxes based on your style or reverse engineered from an existing component.

As a leading manufacturer of high precision gears and drive components, we have the knowledge and expertise to deliver equipment drives that are customized to your specifications. Visit Gearbox Buyers Guide page for useful info and a check-off list to help you select the correct gearbox for your application.
To comprehend better what the backlash is, it is essential to have a clear idea of the gearhead mechanics. Structurally, a gearbox can be an arrangement of mechanical elements, such as for example pinions, bearings, pulleys, wheels, etc. Specific combinations vary, depending on particular reducer type. What’s common for all combinations-they are intended to transmit power from the engine output towards the load so as to reduce speed and boost torque in a safe and consistent manner.

Backlash, also lash or play, is the gap between your tail advantage of the tooth transmitting power from the input and the industry leading of the rigtht after a single. The gap is essential for gears to mesh with each other without getting trapped and to provide lubrication within the casing. On the downside, the mechanical enjoy is associated with significant movement losses, preventing a motor from reaching its optimized performance. First of all, the losses effect negatively performance and precision.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
Smaller between-center distances are achieved either by securing a gearwheel in place with preset spacing or by inserting a spring. Rigid bolted assembly is usually typical of bidirectional gearboxes of the bevel, spur, worm or helical type in heavy-duty applications. Springtime loading is a better choice to keep lash at acceptable values in low-torque option. Mind that the locked-in-place set up requires in-provider trimming since teeth tend to wear with time.

The opportunities are endless with zero backlash planetary gearbox!
