ABSTRACT:
A shaft retainer device that comprises three major components: a barrel shaped housing, a leverable gripping assembly which is located inside the housing along its central axis, and a key lock in one end of the housing. When the device is locked, the gripping assembly radially grips any grooved shaft that has been inserted in the housing preventing shaft withdrawal. When unlocked by a key, the gripping assembly is spread apart, releasing its radial grip on the groove of any grooved shaft that has been previously inserted in the device. The shaft retainer will work equally well with any shaft that has a raised ridge or a stepped edge around its circumference, and can accommodate a range of shaft diameters. The device is small, light weight and economical to produce.
