Sealing bearing

Abstract

The invention discloses a sealing bearing which comprise a bearing box, a transmission shaft, a bearing body, a bearing cover and a sealing cover. The transmission shaft is installed in the bearing box. One end of the transmission shaft is fixed to the bearing body, and the other end of the transmission shaft is installed in the sealing cover. The sealing cover is fixedly installed at one end of the bearing box. The bearing body is used for fixing the transmission shaft and is installed in the bearing cover. A sealing ring is arranged at the matched part of the bearing cover and the bearing body. An oil guide groove is formed between the bearing cover and the bearing body. According to the scheme, the transmission shaft is installed in the bearing box, one end of the transmission shaft is fixed to the bearing body, the other end of the transmission shaft is installed in the sealing cover, and therefore overall sealing of the bearing box is well achieved; and the sealing cover is fixedly installed at one end of the bearing box, the bearing body is used for fixing the transmission shaft and is installed in the bearing cover, the sealing ring is arranged at the matched part of the bearing cover and the bearing body, the oil guide groove is formed between the bearing cover and the bearing body, the transmission shaft is fixed through the bearing and the bearing cover, so that the oil inlet amount of the transmission shaft is reduced, the oil pressure is reduced, the sealing effect is improved, and the sealing effect of the bearing is ensured.

Description

technical field [0001] The invention relates to a sealed bearing and belongs to the technical field of reduction boxes. Background technique [0002] Oil leakage often occurs at the shaft end of the reduction box of the pumping unit, which leads to the lack of proper cooling and lubrication for the bearings and gears, which reduces the service life of the equipment, and the oil production team needs to stop the well frequently to wipe the oil and replenish the oil, which affects the production of crude oil. Efficiency, and increased human labor, therefore, need to improve the reducer. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to propose a sealed bearing with good sealing effect. [0004] The technical solution of the present invention is achieved as follows: a sealed bearing, including a bearing box, a transmission shaft, a bearing, a bearing cover, and a sealing cover; the transmission shaft is inst...
