In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent bush structure of driving-disc oil leak, includes main disk body and bush, be equipped with the installing port that corresponds with the bush on the main disk body, the thread bush has been cup jointed to the one end screw thread of bush, be equipped with a plurality of spouts that the symmetry set up on the outer wall of main disk body, fixedly connected with slide bar in the spout, L type kelly has been cup jointed in the slip on the slide bar, around being equipped with a plurality of draw-in grooves that correspond with L type kelly on the outer wall of thread bush, the fixed stop collar that has cup jointed of one end that the thread bush was kept away from to the bush, one side that the stop collar is close to the main disk body is fixed to.

Preferably, a rubber pad is fixedly bonded on one side of the threaded sleeve opposite to the main disc body.

Preferably, a second sealing ring is fixedly sleeved on the outer wall of the bushing.

Preferably, a wear-resistant ring is fixedly inserted on the inner wall of the bushing.

Preferably, a connecting flange is fixedly sleeved at one end of the bushing, which is far away from the threaded sleeve.

Preferably, the sliding rod is sleeved with a spring, and two ends of the spring are respectively fixedly connected with the L-shaped clamping rod and the inner wall of the sliding groove.

Has the advantages that:

1. the sealing performance of the bushing can be improved through the arrangement of the sealing mechanisms, so that the using effect of the bushing is improved;

2. the wear-resisting ability of bush inner wall can be strengthened in the setting of wear-resisting cover, and flange can make things convenient for bush and exterior structure to be connected simultaneously.

Drawings

Fig. 1 is a schematic structural diagram of a bushing structure for preventing oil leakage of a driving disc according to the present invention;

fig. 2 is a schematic side view of the bushing structure bushing for preventing the driving disk from leaking oil according to the present invention.

In the figure: the anti-abrasion device comprises a main disc body 1, a lining 2, a thread bushing 3, a sliding rod 4, a clamping rod 5L-shaped, a limiting sleeve 6, a first sealing ring 7, a second sealing ring 8, a wear-resistant ring 9, a connecting flange 10 and a spring 11.

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.

Referring to fig. 1-2, a bushing structure for preventing oil leakage of a driving disc comprises a main disc body 1 and a bushing 2, wherein the main disc body 1 is provided with a mounting opening corresponding to the bushing 2, and the outer wall of the bushing 2 is fixedly sleeved with a second sealing ring 8 to enhance the sealing property between the bushing 2 and the inner wall of the mounting opening;

in the embodiment, a wear-resistant ring 9 is fixedly inserted on the inner wall of a bushing 2, so that the wear resistance of the inner wall of the bushing 2 is enhanced, a threaded sleeve 3 is sleeved at one end of the bushing 2 in a threaded manner, so that the bushing 2 is conveniently fixed, a connecting flange 10 is fixedly sleeved at one end of the bushing 2, which is far away from the threaded sleeve 3, so that the bushing 2 is conveniently connected, a rubber pad is fixedly bonded at one side of the threaded sleeve 3, which is opposite to a main disc body 1, so as to play a role in sealing and elastic buffering, a plurality of symmetrically arranged sliding grooves are formed in the outer wall of the main disc body 1, and sliding rods 4 are;

in the embodiment, an L-shaped clamping rod 5 is sleeved on a sliding rod 4 in a sliding manner, so that a threaded sleeve 3 can be conveniently fixed, a spring 11 is sleeved on the sliding rod 4, two ends of the spring 11 are respectively and fixedly connected with the L-shaped clamping rod 5 and the inner wall of a sliding groove, and a plurality of clamping grooves corresponding to the L-shaped clamping rod 5 are arranged on the outer wall of the threaded sleeve 3 in a surrounding manner;

in this embodiment, a limiting sleeve 6 is fixedly sleeved at one end of the bushing 2 far away from the threaded sleeve 3 and used for limiting the horizontal position of the bushing 2, and a first sealing ring 7 is fixedly bonded on one side of the limiting sleeve 6 close to the main disc body 1 to enhance the sealing performance of the bushing 2.
