Document Type and Number:
WIPO Patent Application WO/2017/169419
Kind Code:
A1
Abstract:
Provided is a hollow-type rotary actuator. For example, a rotary actuator 2 used in a joint part of an industrial robot is provided with: a hollow motor 7 having a hollow rotary shaft 13; a hollow reduction gear 8 having a hollow input shaft 20 that is arranged coaxially with the rotary shaft 13 and is coupled to the rotary shaft 13; a tubular member 26 disposed on the inner peripheral side of the rotary shaft 13 and the input shaft 20; and a holding member 32 that holds one end side of the tubular member 26. The holding member 32 is provided with a holding part 32a, in which a through-hole 32b that leads to the inner peripheral side of the tubular member 26 is formed. In the rotary actuator 2, one end side of the tubular member 26 is held by the holding part 32a, and the other end side of the tubular member 26 is movably fit to the output side portion of the hollow reduction gear 8.
