Abstract

The invention provides a forklift drive axle assembly with a wheel edge locking structure. The wheel edge locking structure comprises round nuts, a gasket and fastening bolts, two threaded holes and two round holes are formed in each round nut, the threaded holes and the round holes are uniformly distributed on the same pitch circle of the end face of each round nut, and the threaded holes and theround holes are distributed alternately; a plurality of through holes and an inner tooth are formed in the gasket, and the pitch circle where the through holes are located corresponds to the positions of the threaded holes and the round holes, and the inner tooth is arranged on an inner hole of the gasket. After the round nuts adjust bearings to be pre-tightened and rotate by different angles, some through holes always align with the threaded holes in the round nuts so that the fastening bolts can be fastened on the round nuts, and the inner tooth is used for being clamped in a reserved groove of an axle housing axle head for rotation prevention. According to the assembly, the round nuts can not be loosened when the large torque is borne after a bearing clearance is adjusted to be reasonable, the system resistance can not be increased, the structure is simple and compact, the anti-loose and reliable performance is achieved, the quality is stable, and the realization of small-space layout is facilitated.

Description

technical field [0001] The invention belongs to the technical field of locking and anti-loosening, and in particular relates to a forklift drive axle assembly with a wheel edge locking structure. Background technique [0002] see Image 6 -- Figure 9 , the forklift driving axle wheel edge locking structure currently on the market is mainly made up of 2 round nuts 10, 1 round nut with stop washer 20. When installing the drive axle assembly, first install the brake 4 on the axle housing 5, then seal the first bearing 7, the second bearing 8 and the oil into the hub 6, and then put the brake drum hub assembly into the axle housing 5 together. , and finally screw a round nut 10 into the axle head end of the axle housing 5 to press the outer bearing 8, and rotate 1 / 8 turn to make the bearing have a certain clearance. After the bearing clearance is adjusted, install the round nut with a stop washer 20. Insert any outer tongue 201 of the stop washer 20 into the notch 101 of the ...
