Quick Details
Specifications
the eccentric rolling-mechanism gearheads known as cycloidal reducers are a type of servo gearing that has an input shaft that drives a bearing assembly. this in turn drives a cycloidal disc (sometimes called a cam) that connects to an output shaft. the cam has lobes or teeth that engage with a cam follower typically with pin or needle bearings. the eccentric cam rotation induces rotation of an output shaft at a lower speed and higher torque than the input.
the main advantage of cycloidal reducers is their property of zero or near-zero backlash (to 1 arc-min.) which makes for high precision and high accuracy. this is especially in demand where highly precise and accurate positioning is required, for instance in robotic applications, machine tools, and similar applications. Cycloidal reducers also feature rolling as opposed to sliding contact, thus experiencing less overall wear. Some cycloidal speed reducers offer zero backlash by combining a compound reduction cam with a full complement of needle-bearing cam followers.
Because of the pin-and-gear structure, cycloidal gearing maintains continuous and distributed power-transmission contact for higher shock resistance than traditional reducers. In fact, some variations can withstand transitory exposure to quadruple their rated torque. High torque density makes for ratios to 185:1 in reasonable gearbox footprints.
Characteristics:
1.High Precision: the multi-tooth is meshing at the two positions which are 180° from each other at the same time, so that the effluence on transmission accuracy due to gear pitch error and the cumulative pitch error can be balanced and reach to extremely high transmission accuracy.
2.Transmission ratio: a single-stage strain wave gear transmission ratio can reach to 30~500.
3.Load carrying capacity: the meshing area as well as the number of teeth at engage stage is large, so load which is divided on each tooth, could be smaller accordingly, while the overall load could be very large.
4.Size & weight: comparing with the conventional gear device, it has the features of miniaturization and light-weight.
5.Transmission efficiency: the transmission efficiency of strain wave gear reducer can reach to 70%~85%.
6.Smooth gearing, non-impact, and lower noise.
