Document Type and Number:
WIPO Patent Application WO/2018/131228
Kind Code:
A1
Abstract:
An Oldham coupling (1) interposed between two connection destinations having different usage temperatures. The Oldham coupling has a first member (10) to which a rotary shaft (50) of one connection destination is connected, a second member (30), and a third member (40) connected to a rotary shaft of the other connection destination. First protrusions (16A, 16B) rising upright in the concentric direction, which is the direction parallel to the rotary shafts, and extending in a first direction (X), which is the diameter direction of the rotary shafts, are provided on one member, that is, the first member or the second member, first grooves (32A, 32B) mating with the first protrusions so as to be capable of sliding in the first direction are formed on the other member, that is, the first member or the second member, a second groove (39) extending in a second direction (Y) orthogonal to the first direction is formed on one member, that is, the second member or the third member, a second protrusion (41) mating with the second groove so as to be capable of sliding in the second direction is provided on the other member, that is, the second member or the third member, and at least one member among the first member, the second member, and the third member has a heat dissipation structure wherein multiple concentric circular tube parts having a hollow section and having different diameters are arranged with intervals therebetween, and the intervals between the multiple tube parts are connected by means of bridging parts.
