Title:
REDUCTION GEAR AND METHOD FOR MANUFACTURING REDUCTION GEAR SERIES
Document Type and Number:
WIPO Patent Application WO/2019/181965
Kind Code:
A1
Abstract:
[Problem] To obtain a reducer and a method for manufacturing a reducer series with which the increase in the number of components can be minimized and the size in an axial direction can be reduced. [Solution] A method for manufacturing a reduction gear series configured including: an orthogonal-shaft reduction gear 100 having a first reducer 1 that has a hollow input shaft 14a, a second reducer 2 composed of a bevel gear 41 provided to the input shaft 14a and a bevel pinion 42 that meshes with the bevel gear 41 and rotates about an axis O3 orthogonal to an axis O1 of the input shaft 14a, a casing 3 that houses the second reducer 2, and a tubular member 4 that is secured to the casing 3 and that coaxially passes through the input shaft 14a and the bevel gear 41; and a parallel-shaft reduction gear configured using members having the same shapes as an internally toothed gear 11, an externally toothed gear 10, and a carrier 13 used in the first reducer 1; said manufacturing method characterized in that the parallel-shaft reduction gear is configured using an input shaft of which the shape of an eccentric part is the same as that of the input shaft 14a used in the orthogonal-shaft reduction gear 100, and which has greater axial length than the input shaft 14a.
