Gearboxes are drive elements that can boost torque, reduce or increase speed, reverse rotation, or modify the direction or rotation of a driveshaft. Additional clearance, known as backlash, is built in to the gearbox components to prevent gears from binding, which in turn causes overheating and will damage one’s teeth. A potential downside of this, however, is that backlash can make it harder to achieve accurate positioning.
Low backlash gearboxes possess a modified design to lessen or eliminate backlash. This consists of using gears and bearings with close tolerances and making sure parts are properly matched to minimize zero backlash gearbox dimensional variants. Backlash is often limited to 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 quickness reducers in an array of options which includes miniature and low backlash styles. Our engineers can also create customized low backlash gearboxes based on your design or reverse engineered from a preexisting component.
As a leading manufacturer of high precision gears and drive parts, we have the experience and expertise to provide equipment drives that are personalized to your specifications.

To understand better what the backlash is, it is vital to truly have a clear notion of the gearhead mechanics. Structurally, a gearbox is an arrangement of mechanical elements, such as for example pinions, bearings, pulleys, wheels, etc. Specific combinations vary, based on specific reducer type. What’s common for all combinations-they are designed to transmit power from the engine output towards the strain in order to reduce acceleration and enhance torque in a safe and consistent manner.
Backlash, also lash or perform, is the gap between the tail edge of the tooth transmitting power from the insight and the industry leading of the immediately following 1. The gap is vital for gears to mesh with one another without getting stuck and to provide lubrication within the casing. On the drawback, the mechanical perform is associated with significant motion losses, preventing a engine from reaching its optimized performance. To begin with, 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 can be typical of bidirectional gearboxes of the bevel, spur, worm or helical type in heavy-duty applications. Spring 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-assistance trimming since teeth tend to wear with time.
