摘要:
A rotating assembly (22) is used, for example, as a crank assembly in an orbiting radial motor (14) to drive ring gears (16,17) or in a multiple output speed increaser or reducer. The use of more than one rotatable section connected to a first member (30), such as more than one throw on a crankshaft, can cause unequal load sharing between the sections. The rotating assembly (22) has a first member (30), a second annular member (32) positioned about the first member (30) and a third annular member (34) positioned about the second annular member (32). A first bearing element (48) positioned between the first and second members (30,32) supports the second member (32) in rotation relative to the first member. A second bearing element (56) positioned between the second and third members (32,34) supports the third member (34) in rotation relative to the second member (32). In the assembly (22), each respective bearing element (48,56) is in continuous contact with and about the entire relative surface peripheries of the respective relative members (30,32) (32,34).
