Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly and debugging, in particular to a bearing with an oil guiding function and an operating method thereof. Background Art

[0002] Sliding bearings are components that fix and reduce the load friction coefficient during mechanical transmission. Specifically, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed.

[0003] In the prior art, the sleeve is a cylindrical mechanical part sleeved on the rotating shaft and is an important component of the sliding bearing. When the gap between the rotating shaft and the outer tube is very small, a smooth sleeve is used as a bearing. When the sleeve is processed, in order to meet the lubrication requirements, it is necessary to open a number of radial oil holes on the sleeve wall. The oil holes are usually connected to the oil groove on the inner surface of the sleeve to ensure that there is enough lubricating oil in the groove when the sleeve is working.

[0004] During the assembly and commissioning work, in order to ensure the normal operation of the bearing, it is usually necessary to add lubricating oil to the bearing. For viscous lubricating oil, it is usually applied by the staff on the outside of the bearing and evenly spread, and then rotated a few times. For liquid lubricating oil, it is dripped into the lubrication part of the bearing or the oil tank therein, and its uniformity cannot be well guaranteed. There is no good oil guide mechanism, resulting in low lubrication adequacy, and it will also cause the lubricating oil to spill, causing waste and pollution. The existing lubrication method is cumbersome to operate, has poor effect, and will also cause waste and pollution, and cannot meet actual use needs.

[0054] In the actual operation, the oil filling assembly 9 is connected to the connecting thread groove 6 through the external thread connecting ring 8, so that the oil filling assembly 9 is fixedly arranged on the shaft sleeve 2 at an equal distance, and the annular sealing gasket 7 arranged in the connecting thread groove 6 ensures its sealing, thereby preventing oil leakage, and then unscrews the cap 905, and pulls the push-pull handle 1005, so that the movable body 1001 reaches Fig. 9 At the far right side of the box body 901 shown in the figure, the pushing spring 1006 connected to the oil pushing round block 1003 is in a compressed state, and then the oil is poured into the bucket tube 904, and the oil enters the oil storage tank 902 from the oil inlet groove 903, and then the oil in the oil storage tank 902 enters the oil delivery channel 505 in the sleeve 2 through the external threaded connecting ring 8, and finally accumulates and stores in the oil storage chamber 501, and then the cap 905 blocks the bucket tube 904, and then tightens the pushing control rod 1004, and the oil is pressed into the oil storage chamber 501 in the sleeve 2 through the movable body 1001, and the oil in the oil storage chamber 501 overflows and passes through the oil guide hole 502, the annular auxiliary inclined groove 503, and the oil guide inclined groove 504. 04 flows into the contact surface between the shaft sleeve 2 and the bearing body 1, until the positioning groove 1104 set at the bottom end of the movable body 1001 is aligned with the locking strip 1101, and the locking strip 1101 is clamped into the positioning groove 1104 under the action of the reset spring 1103, so as to realize the position positioning of the movable body 1001, and then the push-pull handle 1005 is loosened.

In the above operation process, on the one hand, the purpose of the drainage chute 1007 and the circular hole 1008 set on the top surface of the movable body 1001 is that the oil remaining on the inner wall of the bucket tube 904 and the oil inlet groove 903 can flow to the position of the circular hole 1008 through the drainage chute 1007, and then enter the circular cavity 1002 through the circular hole 1008, so as to avoid the waste of oil, the overflow of oil, and the pollution.
