Pump vertical motor bearing oil injection and discharge structure and vertical motor

Abstract

The invention provides a pump vertical motor bearing oil injection and discharge structure and a vertical motor. The oil injection and discharge structure comprises a rotation shaft and a bearing, wherein the bearing comprises a driving end bearing and a non-driving end bearing, the bearing is mounted on the rotation shaft through a bearing mounting assembly, the rotation shaft is axially providedwith a driving end oil injection channel and a non-driving end oil injection channel, the rotation shaft is communicated with the driving end bearing through the driving end oil injection channel andis used for conveying oil to the driving end bearing, the rotation shaft is communicated with the non-driving end bearing through the non-driving end oil injection channel and is used for conveying the oil to the non-driving end bearing. The oil injection and discharge structure is advantaged in that the lubrication grease on surfaces of bearing balls is continuously coated, the grease is convenient and rapid to replace, work intensity of equipment maintenance personnel is reduced, moreover, temperature rising of a motor can be reduced, service life of the motor bearing is improved, and thereby service life of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of oil injection and discharge structure for motor bearings, and in particular relates to an oil injection and discharge structure for a water pump vertical motor bearing and a vertical motor. Background technique [0002] The bearing is an important part of the motor, the service life of the bearing directly affects the service life of the motor, and the lubrication of the bearing directly affects the key of the service life of the bearing; during the operation of the existing motor, the bearing bears axial force and radial force In the process of rotation, the rolling body rubs against the inner and outer sleeves of the bearing to generate heat and wear. There must be a certain amount of grease in the bearing chamber to lubricate and dissipate heat from the bearing; most of the existing small motors use closed bearings. The bearings of medium-sized motors are open bearings, and it is necessary to ensure th...
