Abstract
The utility model discloses an anti-loose structure of a nut, which belongs to the technical field of machinery manufacturing and solves the defect that the hidden danger of loosening is caused as the locking reliability of the nut in the prior art is not high. The key points of the technical scheme are that the anti-loose structure comprises a nut cushion block, a thrust washer, a check ring and a fastening connecting piece, wherein the nut cushion block is an irregular piece of which the outer side is provided with a small hole, the thrust washer is provided with a clamping jaw, the thrust washer is clamped on the nut, and the clamping jaw stretches into the small hole of the nut cushion block. The anti-loose structure disclosed by the utility model is mainly applied to nut locking positions of transmission systems such as a drive axle and a gearbox.
Description
Technical field:
The utility model belongs to machinery manufacturing technology field, specifically, relates in particular to a kind of nut anti-looseness structure.
Background technique:
Present domestic ransaxle and gearbox input, output terminal nut check, generally adopt nut directly to tighten or nut screwing clamping, screw in compression structure, nut, screw exist and looseningly withdraw from hidden danger in the course of the work, cause nut loosening, reduce the life-span of bearing, reliability is relatively low.This just requires the locking mechanism form that a kind of anti-loosing effect is better, reliability is higher.
Summary of the invention:
For overcoming above-mentioned defective, the utility model provides a kind of can eliminate nut loosening hidden danger, improves the nut check structure of reliable lock.
The utility model is achieved through the following technical solutions:
The nut anti-looseness structure comprises nut cushion block, thrust washer, back-up ring and packing ring, and described cushion block is irregular that the outside is provided with aperture, and described thrust washer is provided with unguiculus, and thrust washer is stuck on the described nut, and unguiculus stretches in the cushion block aperture.
Described nut is provided with groove, and the back-up ring that prevents that thrust washer from axially withdrawing from is installed in the described groove.
Compared with prior art, the beneficial effects of the utility model are: use the utility model to stop the loosening of nut, improved the reliability of nut check.
Description of drawings:
Fig. 1 is plan view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is explosive view of the present utility model.
Among the figure: 1, cushion block; 2, pad; 3, thrust washer; 4, back-up ring; 5, nut; 6, fastening connection piece.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, Fig. 2, shown in Figure 3, the nut anti-looseness structure comprises component such as cushion block 1, pad 2, thrust washer 3, back-up ring 4 and nut 5, cushion block 1 is foraminate irregular an of sidetracking outside, can be assemblied in the irregular groove of fastening connection piece 6, and cushion block 1 can not relatively rotate at irregular groove; Thrust washer 3 inside can be stuck on the nut 5, and outside unguiculus can stretch in the aperture on the cushion block 1, thereby prevent the rotation of nut 5; Nut 5 groove of having got on the bus can be put into back-up ring 4 and prevent that to push down thrust washer 3 it from axially withdrawing from the groove, thereby realizes the locking of nut 5.
Claims (2)
