Abstract

See full text

The present disclosure relates to a manufacturing method of a speed reducer. The speed reducer includes an outer tube, a shaft portion, an input shaft, a first bearing, a speed reducing portion, and an attachment member. The shaft portion has a first receiving surface and a shaft end surface. The outer tube has a second receiving surface. The first bearing has a first inner ring and a first outer ring. The first receiving surface contacts the first inner ring. The second receiving surface contacts the first outer ring. A first machining accuracy is obtained based on a first parallelism between the first receiving surface and the shaft end surface. A second machining accuracy is obtained based on a second parallelism between the second receiving surface and the flange mounting surface. The manufacturing method includes performing machining such that the first machining accuracy becomes higher than the second machining accuracy.
