Water pump dedicated motor

Abstract

The invention discloses a w synchronization ring comprising a shell and a motor body. The motor body is installed in the shell. One end of the shell is provided with a front end cap. The motor body isinternally provided with an output shaft, and one end of the output shaft penetrates through the shaft hole of the front end cap. The shaft hole of the front end cap is internally provided with a sealing shaft ring and a bearing. The output shaft penetrates through the sealing shaft ring and the bearing. The sealing shaft ring is composed of an outer fixed ring and an inner sealing ring, and theouter fixed ring sleeves the periphery of the inner sealing ring. The two ends of the contact inner ring wall of the outer fixed ring and the inner sealing ring are provided with rotating grooves. Rolling balls are flexibly inlaid between the rotating grooves. The sealing shaft ring is arranged in the shaft hole of the front end cap through which the output shaft penetrates, the sealing shaft ringis composed of the outer fixed ring and the inner sealing ring and the inner sealing ring can rotate on the inner ring wall of the outer fixed ring under the effect of the rolling balls without waterseepage so that the sealing performance can be guaranteed without influencing rotation of the output shaft.

Description

technical field [0001] The invention relates to a motor, in particular to a special motor for water pumps. Background technique [0002] Water pump motors can be widely used in different fields, except in places with flammable, explosive or corrosive gases, such as transportation, mixing, printing, agricultural machinery and video processors, they can also be used in machine tools and pumps , blowers, compressors and other ancillary equipment. [0003] However, during the use of the water pump motor, when the output shaft passes through the front end cover, the shaft hole is simply sealed with a single sealing ring, which is prone to water seepage, causing damage to the motor, and the motor is prone to shaking due to vibration during operation. To this end, we propose a special motor for water pumps. Contents of the invention [0004] The main purpose of the present invention is to provide a special motor for water pumps, which can effectively solve the problems in the b...
