摘要

PURPOSE: To enable the common use of parts without lowering strength by equalizing the tie-in dimension to the other party machine, the shaft diameters of first shafts and the outer diameters of eccentric body bearings although with respectively different change gear ratios, and combining the eccentric body bearings of large inner diameter with the eccentric bodies of large outer diameter on the low change gear ratio side, whereas combining those respectively of small inner diameter and outer diameter on the high change gear ratio side. ;CONSTITUTION: Bearings 104a, 104b, 204a, 204b are fitted (as eccentric body bearings) to eccentric bodies 103a, 103b, 203a, 203b. The shaft diameter of an input shaft 101 is equal to that of an input shaft 201, and the eccentric body bearings 104a, 104b are equal in outer diameter to the eccentric body bearings 204a, 204b. The inner diameter of the eccentric body bearings 104a, 104b on the low reduction gear ratio side is large, and the inner diameter of the eccentric body bearings 204a, 204b on the high reduction gear ratio side is small. In addition, the shaft diameters of the input shafts 101, 201 are the same, and also the outer diameters of the eccentric body bearings 104a, 104b, 204a, 204b are the same.;COPYRIGHT: (C)1993,JPO&Japio
