End bracket type bearing

Abstract

The invention provides an end bracket type bearing which comprises a seat. A bearing pad connected with a rotating shaft is arranged in the seat, an end bracket sealing component is arranged on one side of the seat, an air seal cover with a sealed air cavity is arranged on the other side of the seat, an air pipe seat communicated with the sealed air cavity is fixedly arranged on the air seal cover, an air pipe component capable of balancing air pressure in the sealed air cavity and external air pressure is connected onto the air pipe seat, one end of the air pipe component is fixedly connected with the air pipe seat, the other end of the air pipe component is communicated with the outside of the seat, a positioning structure capable of preventing the bearing pad from moving relative to the seat is arranged between the seat and the bearing pad, and an oil ring structure is arranged in the bearing pad. The end bracket type bearing has the advantages of good sealing effect and capabilities of preventing oil or oil mists from entering a motor and prolonging the service life of the motor.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment, in particular to an end cover type bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and the price is also higher. The existing bearing seat usually needs to be sealed by a sealing cover to prevent impurities from entering the motor through the gap. Since the sealing cover is equipped with a bearing, when the bearing rotates at high speed, the temperature of the inner cavit...

AI Technical Summary

Problems solved by technology

Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is also higher.

The existing bearing seat usually needs to be sealed by a sealing cover to prevent impurities from entering the motor through the gap. Since the sealing cover is equipped with a bearing, when the bearing rotates at high speed, the temperature of the inner cavity of the sealing cover is high, resulting in The air pressure in the cavity is relatively high, and it is easy to press the oil or oil mist in the sealing cover into the motor, which seriously affects the service life of the motor
