Stainless steel vibration motor with recirculating cooling water system

Abstract

The invention discloses a stainless steel vibration motor with a recirculating cooling water system. A bearing is embedded into a bearing housing of an end cover; a rotor shaft is arranged in a cylindrical inner shell and is fixed on the bearing and penetrates through the end cover; the tail end of the rotor shaft is fastened with an eccentric block through a key; a spiral channel is arranged in the outer wall of the cylindrical inner shell along a circumferential direction; a stainless steel cylindrical outer shell and the cylindrical inner shell have a seal fit through O-shaped sealing rings; a stainless steel fan housing and a sealing element at the end of the stainless steel cylindrical outer shell have an interference fit and are fastened through bolts; a water inlet pipe is connected to one end of the spiral channel through a water inlet; and a water outlet pipe is connected to the other end of the spiral channel through a water outlet. According to the stainless steel vibration motor, a problem of motor burnout caused by loss of bearing oil in the motor due to inadequate heat dissipation of the existing vibration motor is effectively solved, and meanwhile, a sealing cavity formed by the stainless steel fan housing and the stainless steel fan housing is used, so that the service life of the motor in the high-temperature and corrosive environments can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of horizontal vibration motors, and in particular relates to a stainless steel vibration motor with a circulating cooling water system. Background technique [0002] Motors are widely used in various fields, especially in some precision industries or high-temperature industries. The performance requirements of motors are getting higher and higher, and the working hours of motors are getting longer and longer. With the operation of the motor, the motor heats up, and the motor rotor shaft and The loss of lubricating oil in the bearing bracket will increase the internal friction of the bearing in the motor, damage the bearing, cause the motor to burn out, and affect the normal operation of the motor. It needs to be shut down for inspection and maintenance, which takes a long time, the service life of the motor is low, and the productivity is reduced.

AI Technical Summary

Problems solved by technology

[0002] Motors are widely used in various fields, especially in some precision industries or high-temperature industries. The performance requirements of motors are getting higher and higher, and the working hours of motors are getting longer and longer. With the operation of the motor, the motor heats up, and the motor rotor shaft and The loss of lubricating oil in the bearing bracket will increase the internal friction of the bearing in the motor, damage the bearing, cause the motor to burn out, and affect the normal operation of the motor. It needs to be shut down for inspection and maintenance, which takes a long time, the service life of the motor is low, and the productivity is reduced.

[0003] At present, in some special chemical production enterprises, vibration motors need to operate continuously in high-temperature and corrosive environments. Ordinary casting vibration motors have poor corrosion resistance, which affects the service life of the motors. In addition, vibration motors operate in high-temperature environments. The heat dissipation is better achieved through the motor shell. If the heat inside the motor cannot be taken out by the surrounding refrigerant in time, the operating efficiency of the motor will be reduced and the service life of the motor will be shortened.
