Abstract
A composite joint for a hydraulic system having two parts which rotate relative to each other is formed by the combination of a friction ring of hard material which is mechanically anchored to one of the relative rotating parts as a supporting collar around a ring of more flexible material mounted in a groove of the one part to exert a force on the ring of hard material providing with the joint a relatively large clearance between the two relatively rotating parts.
Claims8
Rotating joint for hydraulic systems comprising:
- an assembly of two parts rotating relative to each other;
- a composite joint of a friction ring of hard material and a ring of flexible materials, the ring of flexible material retained in an annular groove of a first one of said relatively rotating parts and the ring of hard material being mounted therearound as a collar, the ring of flexible material exerting a radial stress on the ring of hard material to ensure the tightness between said parts to mount the parts in relative rotation with a relatively large clearance;
- and
- means to anchor the ring of hard material to said first relatively rotating part to make it integral with said first relatively rotating part.
