Title:
MACHINE WITH HOLLOW PORTION FOR ELECTRICAL WIRING
Document Type and Number:
WIPO Patent Application WO/2023/135688
Kind Code:
A1
Abstract:
A shaft member (100), in which electrical wiring (111, 112) and connectors (131, 132) are integrally formed, is disposed on a hollow portion (10) for electrical wiring that extends through the center of a wave gear device (1). The connectors (131, 132) attached to first and second shaft ends (101, 102) on both sides of the shaft member (100) are each exposed to outside from both ends of the hollow portion (10). During wiring work, external wiring or the like need merely be attached to respective terminals of the connectors (131, 132) exposed to outside. The present invention makes it possible to reduce the risk of disconnection caused by sliding or twisting of the electrical wiring, without the electrical wiring contacting a hollow input shaft (41) forming the hollow portion (10), an end of a second end plate (7), etc. Constraints on the number of wires and wire diameter are also alleviated, and wiring work also becomes simple.
