Abstract
A rotation transmission buffer apparatus for transmitting the turning force of an input rotary body to an output rotary body through an elastic body provided therebetween. The input rotary body is provided with a plurality of engaging spaces, and the elastic body is provided with a plurality of engaging grooves and a plurality of projecting portions which are respectively fitted into the plurality of engaging spaces of the input rotary body. The output rotary body is provided with a plurality of protruding pieces which are respectively fitted into the plurality of engaging grooves of the elastic body.
Claims2
A rotation transmission buffer apparatus comprising:
- an input rotary body having an outer peripheral member, an inner peripheral member, a plurality of joint arms extending between the inner and outer peripheral members, and a plurality of engaging spaces between said joint arms and said inner and outer peripheral members;
- an elastomeric body provided with a plurality of projecting portions which are fitted into said plurality of engaging spaces of said input rotary body, each of said projecting portions having a T-shaped engaging groove formed therein, said elastomeric body having been subjected to a wear resistant reinforcing treatment selected from the group consisting of halogenation and resin coating;
- and an output rotary body provided with a plurality of protruding pieces which are respectively fitted into said plurality of engaging grooves of said elastomeric body;
- whereby the turning forces of said input rotary body is transmitted to said output rotary body through said elastomeric body.
