Title:
ORTHOGONAL AXIS SPEED REDUCER, AND ROBOT EMPLOYING ORTHOGONAL AXIS SPEED REDUCER
Document Type and Number:
WIPO Patent Application WO/2019/181964
Kind Code:
A1
Abstract:
[Problem] To provide an orthogonal axis speed reducer and a robot employing an orthogonal axis speed reducer, with which it is possible for an internal diameter of a tubular member to be increased. [Solution] An orthogonal axis speed reducer 100 comprises a first speed reducing unit 1 having a hollow input shaft 14a, a second speed reducing unit 2 comprising a bevel gear 41 fixed to the input shaft 14a and a bevel pinion 42 which 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 equipped internally with the second speed reducing unit 2, and a tubular member 4 which is fixed to the casing 3 and which penetrates coaxially through the input shaft 14a and the bevel gear 41, wherein the tubular member 4 is fixed to the casing 3 in a cantilevered state, without axially supporting the first speed reducing unit 1 or the bevel gear 41.
