Problems solved by technology

[0003] The disadvantage of the motor with this structure is that the small hole in the windshield and the gap between the casing and the windshield become the passage for dust and impurities to enter. After dust and impurities enter, they will pollute the bearing, resulting in a decrease in the service life of the bearing. It affects the service life of the motor and needs to be improved

Abstract

The invention discloses a sealing device at the end of an air-cooled motor and an installation method for a fan. The air-cooled motor includes an end cover, a rotating shaft, a sealing device and a fan. The installation method includes the following steps: ①The rotating shaft is installed on the end cover through a bearing and the rotating shaft Pass through the end cover; ② Install the sealing device on the rear end surface of the end cover, the sealing device is located on the periphery of the rotating shaft and the rear end of the rotating shaft exceeds the sealing device; ③ Install the fan at the rear end of the rotating shaft and fit the fan to the sealing device Fixed connection; the front end face of the fan is fit and fixedly connected with the rear end face of the positioning ring and the rear end face of the outer protective tube. The invention achieves a good protection effect by adding a sealing device, and at the same time, the sealing device does not affect the original structure and performance of the motor.

Description

technical field [0001] The invention relates to the technical field of air-cooled motors, in particular to a sealing device at the end of an air-cooled motor and a fan installation method. Background technique [0002] The air-cooled motor covers the fan through the windshield. The windshield is provided with a small hole for air intake. There is a large gap between the casing and the windshield. The wind enters from the small hole in the windshield and flows from the The gaps between the covers are blown out for blowing the cooling fins on the case. [0003] The disadvantage of the motor with this structure is that the small hole in the windshield and the gap between the casing and the windshield become the passage for dust and impurities to enter. After dust and impurities enter, they will pollute the bearing, resulting in a decrease in the service life of the bearing. It affects the service life of the motor and needs to be improved. Contents of the invention [0004]...
