Plastic conical disc casing in clamp union - uses casing and sprung projections to clamp disc to casing under click action

摘要

The clamp union is for a disc of steel or other material on a shaft, with the connection formed by a plastic, conical and possibly toothed casing which is possible to assemble in advance via a click mechanism in the disc. This mechanism is formed by sprung projections on the end of the thin part of the casing, which produce an outwards directed spring effect to secure the union between disc and casing. At the other end of the casing is a ring sprung towards the shaft, and this makes it difficult to push back the casing.
