What's Is Cycloidal Drive?

A cycloidal drive or cycloidal speed reducer is a mechanism for reducing the speed of an input shaft by a certain ratio. Cycloidal speed reducers are capable of relatively high ratios in compact sizes with very low backlash.

What is a cycloidal gear used for?

Cycloidal gears also experience lower friction and less wear on the tooth flanks due to their rolling contact and lower Hertzian contact stress. And their good torsional stiffness and capacity to withstand shock loads make them ideal for heavy industrial applications that also require servo precision and stiffness.

What is a cycloidal gear profile?

The cycloidal gear profile is a form of toothed gear used in mechanical clocks, rather than the involute gear form used for most other gears. ... When two toothed gears mesh, an imaginary circle, the pitch circle, can be drawn around the centre of either gear through the point where their teeth make contact.
