Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1: referring to fig. 1-4, the present invention provides a technical solution: an anti-loosening universal joint fork assembly comprises a joint fork 1 and a connecting shaft 2, wherein the joint fork 1 comprises a circular plate 3 which is vertically arranged and fork pieces 4 which symmetrically and vertically extend from the upper end and the lower end of the circular plate 3, the connecting shaft 2 is fixed in the center of one side of the circular plate 3 away from the fork pieces 4, one ends of the two fork pieces 4 away from the circular plate 3 are symmetrically provided with first grooves 5 which are oppositely arranged, and limiting blocks 6 are connected in the first grooves 5; after a needle bearing and a sleeve are installed on a shaft neck of the cross shaft, the shaft neck of the cross shaft is respectively sleeved in the first grooves 5 of the two yoke 1, then the limiting block 6 is installed on the first groove 5 and is fixed by the bolt 10 and the nut 11, and the sleeve on the cross shaft is fixed in the first groove 5 and cannot be loosened, so that the cross shaft is prevented from loosening from the universal yoke due to strong vibration to influence the normal work of the universal joint

Specifically, the joint between the fork 4 and the circular plate 3 has a certain curvature, so that the fork 4 is not easily broken on the circular plate 3.
