Abstract
There are disclosed nut locking assemblies comprising a washer adapted to slide over a spindle and be keyed to it, and a lock-ring to the rear of the washer and secured to the washer against relative rotation. The nut abuts the washer. The lock-ring is slidable axially so that in a forward position it is disengaged from the nut but in a rearward position serrations on the lock-ring engage corresponding serrations on the nut to lock the nut against rotation. An annular space between the washer and the lock-ring contains a resilient ring which can be strained to alter its diameter. In its normal unstrained condition this ring holds the lock-ring in its locking position. When it is desired to move the lock-ring to its unlocked position it is pushed forward to disengage the serrations of the lock-ring from those of the nut. This strains the resilient ring to a different diameter so that when the pressure is removed from the resilient ring it resumes its original unstrained diameter to push the lock-ring back into engagement with the nut, thereby locking it against rotation.
