Gear drive assembly

A compact drive assembly has a skew axis input gear set and a parallel axis output gear set. The input gear set includes a pinion having at least one helical thread thereon which drivingly engages a face gear. The face gear of the input gear set and the spur gear of the output gear set are integrall...

Zusammenfassung:	A compact drive assembly has a skew axis input gear set and a parallel axis output gear set. The input gear set includes a pinion having at least one helical thread thereon which drivingly engages a face gear. The face gear of the input gear set and the spur gear of the output gear set are integrally molded of a suitable plastic material forming a cluster gear. The output gear of the output gear set has a tooth configuration which is compatible with that of the spur gear which drives it. The gear assembly is particularly adapted for use in a power operated automobile window actuator and has the following advantages over existing actuators: (a) 50% reduction in size and weight, (b) capable of performing much higher input/output reductions despite decreased size, (c) needs no brake since the assembly is self-locking, (d) can be used with a smaller high speed motor which is less expensive.
