Nut with locking ring - has surfaces on nut and ring forming inclined planes to force ring against flexible tongues which lock onto threads.

摘要

The ring such as a nut has a basic element (2) with axial projections which have conical surface areas on the outside. At the transition with the projections the basic element has a step contg. a security ring (3). Both the basic element and the security ring have facing support (13, 14) which together form a slanting plane for the axial displacement of the security ring opposite the basic element. Where the nut has an inner thread (7) the pitch of the support faces can be smaller or greater than the pitch of the inner thread. USE/ADVANTAGE - The locking ring on a nut can be securely fixed on an axis of a shaft etc. without the need for special tools.
