After the rotary drilling rig is constructed for a long time, lubricating grease between the long shaft and the shaft sleeve can lose efficacy and becomes waste lubricating grease. At present, waste lubricating grease in a long shaft mechanism can only be discharged from two sides, most of the waste lubricating grease in the long shaft mechanism cannot be discharged, so that new grease is difficult to drive in, and the long shaft mechanism cannot be sufficiently lubricated and is easy to damage.

The sleeve here belongs to a part of a plain bearing. Specifically, the shaft sleeve is a cylindrical mechanical part sleeved on the rotating shaft and is a component of the sliding bearing. Typically, the sleeve is an interference fit with the bearing seat and a clearance fit with the shaft.

Further, sliding bearings (sliding bearings), bearings that operate under sliding friction. The sliding bearing works stably and reliably without noise. Under the action of the lubricant, the surfaces of the sliding bearings are separated by the lubricant without direct contact, so that the friction loss and the surface wear can be greatly reduced, and the lubricant also has certain vibration absorption capacity. The sliding bearing is generally applied under the working condition of high speed and light load.
