Abstract
Official abstract text for this publication.
This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tolerance ring comprising: a ring main body, which is substantially in a ring shape; and spring-like portions, which are formed on the ring main body and are elastically deformable in a radial direction of the ring main body, wherein the spring-like portions comprise a plurality of main protrusions and a plurality of sub-protrusions, a protruding amount of which is smaller than that of the main protrusions, and grease is stored in only concavit…
