ABSTRACT:
A locking device especially adapted to secure relatively movable concentric members together. The device is particularly useful for locking a bearing on a shaft or within a housing. Broadly, the device includes a locking part disposed between first and second concentric members and biased into a frictional engagement with a first of the members so that when such member moves relative to the second member, the locking part is moved frictionally engaging the second member for locking the members together. In one form of the locking device a coil spring is wound about and frictionally engages a first member within a second member and has a tang engageable with a recess in the second member for interlocking the members responsive to rotation of the first member. Another embodiment of the locking device includes an arcuate-shaped spring having wedge portions engaging a first member within a recess of the second member. The recess of the second member is defined by eccentric arcuate locking surface portions converging toward the first member whereby the locking part is moved into wedging relationship between the first and second members for interlocking such members.
