PLANETARY ECCENTRIC FINGER TYPE TROCHOID TYPE GEAR

摘要

PURPOSE: To prevent the early wear of a supporting bearing by mounting one unit consisting of an Oscillation generator having at least three disc wheels engaged with a pin and a disc having a pin for a torque takeout mechanism on two Oldham's couplings. CONSTITUTION: A unit consisting of an oscillation generator 11 having at least three disc wheels 4a-4c engaged with a pin 1 and a pin 7 having a pin 7 for a torque takeout mechanism is mounted on two Oldham's couplings 13, 14. Cuttings are provided in gaps between the teeth of the disc wheels 4a-4c to form gaps to the ends of the teeth. In such a structure, a gear is formed with no gap.
