DIFFERENTIAL OSCILLATING TYPE SPEED REDUCER

摘要

PROBLEM TO BE SOLVED: To miniaturize a differential oscillating type speed reducer by devising a supporting structure of a crankshaft.;SOLUTION: This differential oscillating type speed reducer is provided with an input shaft 21, the crankshaft 48 having an eccentric part 48a and rotating interlocked with the input shaft 21, a pair of crank bearings 56, 57 to support the crankshaft 48, a cylinder 13 at least at a part in the axial direction at the inner peripheral part of which an internal tooth pin 31 is arranged, a pinion 44 having an external tooth engaged with the internal tooth pin 31 and revolving interlocked with the eccentric part 48a and a carrier 22 revolving interlocked with the revolution of the pinion 44. An intermediate bearing member 46 to rotatably support the crankshaft 48 between the crank bearings 56, 57 is provided.;COPYRIGHT: (C)2009,JPO&INPIT
