Abstract
The utility model relates to a locking mechanism which comprises a rotating shaft, a round nut and a locking gasket, wherein the end part of the rotating shaft is provided with a thread, the round nut is screwed on the thread, the locking gasket is fixed on the rotating shaft, the outer diameter of the round nut is provided with notches, and the locking gasket is provided with locking jaws which are clamped on the notches of the round nut. Five locking jaws are uniformly distributed on the locking gasket, and six notches are uniformly distributed on the round nut. During assembly, after the moment of force meets the condition, most part of one jaw is matched with the notch, and after the moment of force is adjusted properly, the jaw can be jointed on the notch, therefore, the phenomenon of unstable fixing under locking condition can not occur, and time and labor are saved.
Description
Technical field
The utility model relates to a kind of locking mechanism.
Background technique
In the existing mechanical transmission system, the fixed structure that has is fixed by round nut.Owing to produce factor affecting such as vibration in the running of driving mechanism, round nut need be locked.Some locking mechanisms commonly used are that lock washer is installed on running shaft, and the locking jaw of the setting on the pad is stuck in the notch that is provided with on the round nut.But owing to the requirement in order to lock, round nut is not screwed to the position sometimes, makes and fixes built on the sand.
Summary of the invention
The purpose of this utility model provides and a kind ofly can be screwed to the position at round nut, when fixedly securing, can effectively realize the mechanism that locks.
The technical solution of the utility model is, mechanism comprises running shaft, round nut, lock washer, end on the running shaft is provided with screw thread, round nut is screwed on the described screw thread, lock washer is fixed on the running shaft, described round nut external diameter is provided with notch, and described lock washer is provided with locking jaw and is stuck on the notch on the described round nut.Locking jaw on the described lock washer is uniform 5, and the notch on the described round nut is uniform 6.Simultaneously, fixing can the employing of lock washer is provided with groove on running shaft, the inner diameter location of lock washer be provided with boss and with described running shaft on groove fit.
When locking that needs are fixed, earlier the boss of lock washer is aimed at the groove on the running shaft, tighten round nut.Under the requirement of satisfying moment, because pad has 5 pawls, and 6 notches are arranged on the round nut, suitably adjust moment, just can will aim at fully apart from immediate a pair of pawl and notch, just can pawl be got on the notch, all the other 4 are grabbed and cut, finish installation and lock.
The utility model adopts lock washer, can realize the locking of round nut, simultaneously, the locking jaw on the lock washer is uniform 5, notch on the described round nut is uniform 6, can make when assembling, after moment satisfies condition, a pawl major part will be arranged last notch, suitably adjust moment, therefore just can get on the notch, can not appear at fixing not firm phenomenon under the situation of locking grabbing, time saving and energy saving.
