Separation blade structure for fixing motor rotor part and assembling method

Abstract

The invention discloses a separation blade structure for fixing a motor rotor part. The separation blade is inverted U-shaped. Theseparation blade structure is characterized in that the front end is provided with a transverse arch (100), the top end is provided with a turn-over surface (300), two sides of the top end are respectively provided with an independent turn-over edge (200), two feet of the bottom end are respectively provided with left and right inclined edges (400), the independent turn-over edges (200) are attached to a reduction shell (2), and the arch (100) is in contact with a bearing (301) of the rotor part. By redesigning the structure of the separation blade, the elasticity of the separation blade is improved in a limited space, the percent of pass of products is increased, the reject ratio of rotor part bearings is greatly reduced, automatic feeding can be achieved, and the separation blade is suitable for large-scale production.

Description

technical field [0001] The invention relates to a baffle structure for fixing a rotor part of a motor, which can be used for a motor that needs to limit the position of the rotor part. Background technique [0002] The existing block structure of the rotor part of the motor is easy to cause damage to the bearing of the rotor part, and has high requirements on the size of the reducer housing, resulting in low efficiency in the processing process, high production cost, and high defect rate, so it cannot be mass-produced. [0003] Such as Figure 2-4 , the structure of the existing motor block includes bosses (101), barbs (102) and flanges (103), wherein the back of the boss (101) fits with the inner side of the reducer housing (201), and the front side fits with the rotor part ( 3) The bearing (301) is in contact with the rotor part (3) through a certain interference, and the boss (101) has a certain elastic effect, which is used to adjust the interference with the rotor part ...

AI Technical Summary

Problems solved by technology

As mentioned above, because the groove surface (202) is a non-processed surface, the force of the blocking piece (1) is inconsistent when it is pressed into the reducing housing (2), which is easy to cause deflection. In addition, the blocking piece (1) and the The interference of the bearing (301) is inconsistent, which will cause difficulty in assembly as a whole, more damage to the bearing (301), low pass rate, and high production cost
