Intermediate coupling member arrangement between rotary components

摘要

The coupling is for use between components whose axes of rotation are offset. It has intermediate members turning via a bearing on a common axis. Lubricant is supplied to the bearing from a reservoir. Each outer member (16) has edges (54,56) extending radially inwards beyond the bearing (22), so as to prevent lubricant escaping from it under centrifugal force. They can also extend beyond the inner edge of the reservoir, which is situated at the inside of the bearing. The bearing can be a plain bush, with working faces bearing against the outermost member and the next one inside it. The reservoir can be formed by grooves in the bearing surface of the latter member.
