Motor bearing lubricating structure and motor for wet operating pump

Abstract

The invention relates to a motor bearing lubricating structure for a wet operating pump. The motor for the wet operating pump comprises a sleeve, a stator component and a rotor component, wherein the sleeve is positioned between the stator component and the rotor component; a bearing is arranged between a rotating shaft of the rotor component and the bottom of the sleeve; and one or more fluid channels is/are formed on a bearing body. The invention also relates to a motor employing the bearing lubricating structure. The stator component is integrally and seamlessly connected with the sleeve through a pole shoe of the stator component; and a stator core of the stator component is connected with the pole shoe through a chase mortise structure in a matching mode. The fluid directly penetrates through the fluid channels and contacts and impacts the bearing, the problems that the bearing is dry in operation to generate high-degree wear and the temperature is raised are solved, and the service life of the motor bearing for the wet operating pump is greatly prolonged; and meanwhile, the motor for the wet operating pump is simple in structure, low in manufacturing cost and suitable for large-scale popularization and application in production.

Description

technical field [0001] The invention relates to a motor component for a wet-running pump, in particular to a bearing lubrication structure for a wet-running pump motor, and also relates to a wet-running pump motor using the bearing lubricating structure, especially suitable for use in the field of dishwashers . Background technique [0002] The pump is a machine that transports fluid or pressurizes the fluid. Its working principle is to transmit the mechanical energy generated by the pump motor or other external energy to the fluid to increase the energy of the fluid. It is mainly used to transport fluids including water, oil, acid and alkali, Emulsions, suspensions, and liquid metals, etc. Pump motors generally include dry-running pump motors and wet-running pump motors. The dry-running pump motor refers to the overall packaging of the motor, and one end of the rotating shaft protrudes from the overall motor package as the energy output end of the pump motor. A sealing c...

AI Technical Summary

Problems solved by technology

Although this bearing lubricating channel structure solves the problem of lubricating the motor bearings of wet-running pumps and avoiding its dry running, the structure of the ring-shaped section set on the bearing support is complicated and the manufacturing cost is high

Simultaneously, there are many defects in the existing disclosed wet-running pump motors.
