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

Embodiment Construction

[0027] Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the present invention is described further, in the present invention, refer to figure 1 , with the front end on the left and the back end on the right.

[0028] Such as Figure 1-Figure 4 As shown, a method for installing the rear end of a motor, the motor includes an end cover 1, a rotating shaft 2, a casing 3, a windshield 4 and a fan 5, the fan 5 includes a back plate 51 located at the front end, and the front end of the back plate 51 is uniform in the circumferential direction. A plurality of fan blades 52 are arranged, and a support ring 53 is provided at the center of the front surface of the back plate 51. The inner diameters of the back plate 51 and the support ring 53 match the outer diameter of the corresponding rotating shaft 2, and the inner edges of the fan blades 52 are connected to the support ring 53. The outer edge of the fan blade 52 is flush with the outer edge of ...

Abstract

The invention discloses a method for installing the rear end of a motor. Insert the inner protective device forward along the inner ring surface of the fixed ring; ④Insert the swivel ring along the outer ring surface of the fixed ring from back to front and put in the ball and inject lithium-based grease; The fan, the fan is fixedly connected with the inner protection device and the swivel ring, and the snap ring is installed on the rotating shaft to position the fan; ⑥ Install the wind cover. The present invention achieves an excellent protection effect by adding a fixed ring, an outer protection device, an inner protection device and a swivel ring, while not affecting the original structure and performance of the motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a method for installing the rear end of a motor. Background technique [0002] The air-cooled motor is a kind of motor. The air-cooled motor covers the fan through the wind cover. The wind cover is provided with small holes for air intake. There is a large gap between the casing and the wind cover. The wind flows from the wind cover. The small hole enters and blows out from the gap between the casing and the windshield to blow the cooling fins on the casing. [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 [000...
