[0024] Embodiment one

[0025] Combined Figures 1 to 3 A kind of installation anti-inclination device for skeleton oil seal, including connecting sleeve shaft 1 and oil cover 2, connecting sleeve shaft 1 and oil cover 2 are provided with fixed mechanism 4, and oil cover 2 is provided with installation anti-inclination mechanism 3;

[0026] Fixed mechanism 4 includes connecting ring 48, and connecting ring 48 is fixedly connected to the surface of connecting sleeve shaft 1, and the bottom of oil cover 2 is fixedly connected with fixed seat 42 around, rectangular groove 41 is formed in the inside of fixed seat 42, long rod 49 is fixedly connected around the surface of connecting ring 48, rotating seat 47 is rotatably connected to the surface of long rod 49, fixed plate 45 is fixedly connected to the bottom of rotating seat 47, plug-in block 44 is fixedly connected to the top of fixed plate 45, bolt 43 is screw-connected in the inside of plug-in block 44 and fixed seat 42, and inclined plate 46 is fixedly connected to the side of plug-in block 44 close to connecting sleeve shaft 1;

[0027] The both sides and bottom of rectangular groove 41 are provided as opening, the surface of plug-in block 44 is inserted into the inside of rectangular groove 41, the bottom of inclined plate 46 is fixedly connected with the top of fixed plate 45, and inclined plate 46 is arranged at the bottom of fixed seat 42.

[0028] Further, the toggle rotating seat 47 rotates on the surface of the long rod 49, at this time the rotating seat 47 can drive the fixed plate 45, the fixed plate 45 drives the plug block 44 to be inserted in the rectangular groove 41, and the fixed seat 42 and the plug block 44 are threadedly fixed by the bolt 43, so that the oil cover 2 is fixed on the surface of the connecting sleeve shaft 1, and vice versa, the connecting sleeve shaft 1 and the oil cover 2 are conveniently disassembled.

[0029] Example two

[0030] Reference Figures 1-4 On the basis of example one, further get the installation anti-inclination mechanism 3 including a long shaft 34, the long shaft 34 is fixedly connected to the shaft center of the connecting sleeve shaft 1, the inner ring of the oil cover 2 is fixedly connected with a skeleton oil seal 33, the top of the skeleton oil seal 33 is provided with a groove 35, the inside of the groove 35 is inserted with a convex ring 31, the top of the convex ring 31 is fixedly connected with a tooling 32;

[0031] The inside center of the oil cover 2 is provided with a long hole groove, the surface of the connecting sleeve shaft 1 is inserted into the long hole groove provided in the inside center of the oil cover 2, the surface of the connecting sleeve shaft 1 and the inner ring of the skeleton oil seal 33 are inserted, and the top of the groove 35 is provided as an opening.

[0032] Further, the tooling 32 drives the convex ring 31 to be inserted in the groove 35, the convex ring 31 contacts with the groove 35, when the tooling 32 moves downward under force, the tooling 32 contacts with the oil cover 2, and the skeleton oil seal 33 no longer moves downward, because the whole moves downward under force, so the installation depth of the skeleton oil seal 33 is consistent and flat. If the skeleton oil seal 33 is installed obliquely, it will cause the unilateral interference to be too large, and then increase the friction force between the shaft and the lip of the skeleton oil seal 33, so as to cause the motor to heat up quickly, the bearing grease to be diluted and lost quickly, and the motor bearing to heat up, and then burn the motor, which solves the problem that the skeleton oil seal 33 is installed obliquely and the motor temperature rises.

[0033] In the actual operation process, when the device is used, the tooling 32 drives the convex ring 31 to be inserted in the groove 35, the convex ring 31 contacts with the groove 35, when the tooling 32 moves downward under force, the skeleton oil seal 33 moves downward at the same time, when the lower plane of the tooling 32 contacts with the plane of the oil cover 2, the skeleton oil seal 33 no longer moves downward, because the whole moves downward under force, so the installation depth of the skeleton oil seal 33 is consistent and flat. The lip of the skeleton oil seal 33 is interference fit with the connecting sleeve shaft 1, if the skeleton oil seal 33 is installed obliquely, it will cause the unilateral interference to be too large, and then increase the friction force between the shaft and the lip of the skeleton oil seal 33, so as to cause the motor to heat up quickly, the bearing grease to be diluted and lost quickly, and the motor bearing to heat up, and then burn the motor;

[0034] Since the toggle rotating seat 47 rotates on the surface of the long rod 49, the toggle rotating seat 47 can drive the fixed plate 45 to insert the plug block 44 into the rectangular slot 41, and the fixed seat 42 and the plug block 44 are screwed by the bolt 43, so that the oil cover 2 is fixed on the surface of the connecting sleeve shaft 1, and vice versa, the connecting sleeve shaft 1 and the oil cover 2 are conveniently disassembled.
