Description of the Drawings

[0011] Figure 1 It is a schematic structural diagram of an axial positioning and micro-motion adjustment structure for a cross shaft universal joint of a universal shaft assembly of the utility model. Detailed Description of the Invention

[0012] The following further details the specific implementation manners of the utility model with reference to the drawings.

[0013] As can be seen from Figure 1 the figure, a cross-shaft universal joint axial positioning and micro-adjustment structure of a universal shaft assembly includes a fork body 1 and a cross-shaft universal joint 2. Ear holes 3 are provided at both ends of the fork body 1, and the cross-shaft universal joint 2 is inserted into the ear holes 3. Bearings 4 are used at both ends of the cross-shaft universal joint 2 to be cooperatively connected with the ear holes 3. A snap ring 5 is provided at the outer end of the cross-shaft universal joint 2, and an annular ring body 6 threadedly connected to the fork body 1 is provided outside the snap ring 5.

[0014] When the present utility model is specifically used,

[0015] during installation, the fork body 1 is sleeved at both ends of the cross-shaft universal joint 2, and the bearing 4 is used for interference fit with the ear hole 3. A snap ring 5 is provided at the end of the cross-shaft universal joint 2 for preliminary positioning. An annular ring body 6 is provided outside the snap ring 5 and is threadedly connected to the fork body 1, and the annular ring body 6 is adjusted to the best state of the working technical requirements of the cross-shaft universal joint 2 to complete the connection between the cross-shaft universal joint 2 and the fork body 1.

[0016] A ring groove 7 located outside the ear hole 3 is provided at the end of the fork body 1, the snap ring 5 is snapped into the ring groove 7, a threaded hole 8 located outside the ring groove 7 is provided at the end of the fork body 1, and the annular ring body 6 is threadedly connected to the threaded hole 8.

[0017] During installation, the snap ring 5 is sent into the ring groove 7 by using an installation tool to position the end of the cross-shaft universal joint 2, and the annular ring body 6 is used for fixation outside, so that the entire cross-shaft universal joint 2 is in the best working state.

[0018] The fork body 1 adopts a split structure, and the split fork is convenient for installation.

[0019] An internal hexagonal hole 9 is provided in the middle of the annular ring body 6, which is convenient for tightening the annular ring body 6.

[0020] A plurality of screws 10 are provided on the annular ring body 6. When the annular ring body 6 is adjusted to the best working state of the universal joint 2, the screws 10 are tightened to lock the annular ring body 6 to prevent it from rotating in the working state, thereby reducing the axial movement of the cross-shaft universal joint 2 during work and improving stability.

[0021] Compared with the prior art, the present utility model has the following beneficial effects: By adopting the fixing method of a snap ring and an annular ring body at the end of the cross-shaft universal joint, the axial movement coefficient of the cross-shaft universal joint is greatly reduced, the service life of the universal shaft is doubled, and the maintenance and repair frequencies of the universal shaft assembly are reduced, and the production cost is lowered.
