Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-rotation self-lubricating bearing. Background Art

[0002] Bearings are important parts in modern industry. They mainly include inner rings and outer rings. Cages and rolling elements are arranged between the inner rings and the inner rings. In order to reduce the friction of the rolling elements during the operation of the bearings, the rolling elements need to be lubricated frequently. Frequent disassembly is very troublesome. The market urgently needs a self-lubricating bearing.

[0003] The existing patent (Announcement No.: CN209195962U) proposes a bearing, including a bearing inner ring and a bearing outer ring sleeved outside the bearing inner ring, a retainer is provided between the bearing inner ring and the bearing outer ring, a plurality of rolling bodies are provided on the retainer, and dust covers are provided at both ends of the bearing outer ring, and the dust covers include a large fan ring plate and two small fan ring plates, the outer peripheral surface of the large fan ring plate is fixedly connected to the bearing outer ring, the two small fan ring plates are located between the openings of the large fan ring plate, the small fan ring plate is connected to the bearing outer ring by a short shaft rotation, the edges of the large fan ring plate and the edges of the small fan ring plate are provided with threaded holes, and the large fan ring plate and the two small fan ring plates are threadedly connected to each other through a connecting plate. The problem that the dust cover needs to be removed and then installed when grease is added to the bearing in the prior art is solved, and the operation is cumbersome and inefficient. The advantage is that the grease can be added to the inside of the bearing without removing the dust cover, the operation is fast and simple, and the efficiency is high, and at the same time, the dustproof effect is good under normal conditions.

[0004] The above-mentioned bearing adopts a technical solution for lubrication, in which the edges of the large fan ring plate and the edges of the small fan ring plate are both provided with threaded holes. The large fan ring plate and the two small fan ring plates are threadedly connected to each other through a connecting plate, which solves the problem in the prior art that when adding grease to the bearing for lubrication, the dust cover needs to be removed and then installed again, which is cumbersome and inefficient. The problem with this solution is that although the disassembly process is simplified, the bearing still does not have a self-lubricating effect. Therefore, we propose a high-rotation self-lubricating bearing to solve the above problem. Utility Model Content

[0010] By adopting the above technical solution: the cross-sectional size of the sealing plate is larger than the cross-sectional size of the fixed tube. When the elastic force of the elastic member is restored, the sealing plate blocks the connection between the oil supply box and the fixed tube, so that the lubricating oil in the oil supply box will not flow to the bearing body, avoiding waste of lubricating oil.

[0011] Preferably, the oil supply box is in a "ring" shape and the size of the oil supply box is the same as that of the pressure cover.

[0012] The above technical solution is adopted: the oil supply box is in a "ring" shape and the size of the oil supply box is the same as the size of the pressure cover. When the bearing body is assembled, the inner ring of the bearing body needs to be placed on the object. Since the oil supply box is in a ring shape and the same size as the pressure cover, it will not affect the assembly of the bearing body.

[0013] Preferably, a filling port is fixed on the top of the oil supply box, and a sealing cover is provided on the filling port.

[0014] The above technical solution is adopted: a filling port is fixed through the top of the oil supply box, and a sealing cover is provided on the filling port, which facilitates the filling of the lubricating oil in the oil supply box and prevents the lubricating oil from flowing out of the filling port.

[0015] Preferably, the filling port is provided with threads, and the filling port and the sealing cover are threadedly connected.

[0016] By adopting the above technical solution: a thread is provided on the filling port, and the filling port and the sealing cover are threadedly connected, so that the sealing cover can be easily removed from the filling port.

[0017] Preferably, four of the fixing tubes, fixing frames, sealing plates and elastic members are symmetrically arranged around the axis of the bearing body.

[0018] The above technical solution is adopted: four fixing tubes, fixing frames, sealing plates and elastic members are symmetrically arranged around the axis of the bearing body, so that the assembly range of the bearing body can be increased. When the bearing body is assembled longitudinally, the fixing tube under the bearing body can still flow the lubricating oil into the bearing body.
