摘要

Differential gear has the drive placed above the eccentric shaft. On the eccentric shaft two cogwheels are positioned in rotary manner with number of teeth. Each eccentric shaft revolution rolls away the cogwheel (2) at the crown gear (4) with number of teeth. Since the crown gear is fixed, the cogwheel rotates, and with it the firmly connected cogwheel (3) with number of teeth. The cogwheel rolls away in the crown gear (5) with number of teeth and produces an appropriate relative movement according to the number of teeth. Since these are pulled from each other, a very small angular movement develops at the output gear per eccentric shaft revolution. The eccentric unbalance is compensated by corresponding mass balance (6).
