Gearboxes are drive components that can boost torque, reduce or increase speed, reverse rotation, or change the path or rotation of a driveshaft. Additional clearance, referred to as backlash, is built in to the gearbox components to prevent gears from binding, which in turn causes overheating and can damage one’s teeth. A potential downside 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 consists of using gears and bearings with close tolerances and ensuring parts are properly matched to minimize dimensional variants. Backlash is often limited by 30 arc-min, or as low as 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 offer gearboxes and swiftness reducers in a wide variety of options including miniature and low backlash designs. Our engineers can also create customized low backlash gearboxes based on your style or reverse engineered from an existing component.

As a leading manufacturer of high precision gears and drive elements, we have the knowledge and expertise to deliver gear drives that are customized to your specifications. Go to Gearbox Buyers Guide page for useful information and a check-off list to assist you select the right 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 is an arrangement of mechanical components, such as pinions, bearings, pulleys, tires, etc. Specific combinations vary, depending on particular reducer type. What’s common for all combinations-they are designed to transmit power from the engine output towards the strain so as to reduce swiftness and increase torque in a safe and consistent manner.

Backlash, also lash or perform, is the gap between your tail advantage of the tooth transmitting power from the insight and the leading edge of the immediately following 1. The gap is essential for gears to mesh with each other without getting stuck and to provide lubrication within the casing. On the downside, the mechanical enjoy is associated with significant motion losses, preventing a motor from reaching its optimal performance. First of all, the losses impact negatively performance and precision.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
Smaller between-middle distances are achieved either by securing a gearwheel in place with preset spacing or by inserting a spring. Rigid bolted assembly is standard 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 suitable values in low-torque remedy. Brain that the locked-in-place arrangement requires in-services trimming since teeth tend to wear with time.
