Abstract
An arrangement for locking a nut on a spindle, e.g. for fixing roller bearings on wheel axles, comprising a lock washer with an axial pin, a lock plate and a lock ring. The lock plate has an opening with twelve corners in which a non-rotatable nut has thirteen depressions for the axial pin. The lock washer is disposed non-rotatable on the spindle, and for this purpose it can have an approximately polygonal opening for an axle portion of corresponding cross section. When the lock plate surrounds the nut and the axial pin projects into one of the depressions, the nut is fixed against turning. The lock plate is held in place by the lock ring which lies in a groove in the nut.
Claims4
An arrangement for locking a nut to an axle spindle comprising a lock plate having a plurality of equally peripherally spaced depressions or cavities, said plurality differing by one from twice the number of corners of the nut, and a lock washer having an axially projecting member projecting into one of the depressions or cavities, one of said lock plate and said lock washer being a nut-receiving member having a nut-receiving opening provided with a number of interior corners equal to twice the number of exterior corners of the nut, the other of said lock plate and said lock washer being non-rotatably joined to the spindle, and separate stop means engaging the nut to prevent axial movement of the nut-receiving member toward the end of the spindle.
