Combining device of motor stator

Abstract

The invention discloses a combining device of a motor stator. The combining device comprises a base, a positioning unit, a clamping unit and a combining unit, wherein the positioning unit is arranged in the base; the clamping unit is used for clamping the stator; the combining unit is used for combining the base with the positioning unit; the base comprises a bottom plate and a shaft pipe integrally extending upwards from the bottom plate; the positioning unit comprises a shaft sleeve which is arranged in the shaft pipe and is provided with an upward opening and an enclosed bottom; and the clamping unit and the combining unit are combined with the shaft pipe and the shaft sleeve in a matching way. Due to the adoption of the shaft pipe integrally extending from the bottom plate in the invention, the component quantity can be effectively reduced for simplifying the assembling process, and the center of each component is more consistent; and by matching with the blind-hole-shaped shaft sleeve, lubricating liquid can be effectively prevented from overflowing, the production cost can be lowered, and the problems of vibration, noise, power loss and the like can be effectively solved.

Description

technical field [0001] The invention relates to a coupling device, in particular to a coupling device of a motor stator. Background technique [0002] refer to figure 1 , is the combination structure disclosed in Figure 6 of the invention patent case No. I231085 "Combined Structure of Motor Shaft Tube" in Taiwan, China, including a shell base 11, a shaft tube 12 located in the center of the shell base 11, a set of A circuit board 13 arranged on the shell base 11, a stator 14 arranged on the circuit board 13 to be driven by power supply to generate a magnetic field, a shaft sleeve 1 arranged in the shaft tube 12, a shaft sleeve 1 arranged in the shaft sleeve The bearing 16 in 15, a top support member 17 arranged between the shaft sleeve 15 and the shaft tube 12, a rotating shaft 18 pivotally passing through the bearing 16 and the shaft sleeve 15, and a rotor connected to the rotating shaft 18 19 , a positioning ring 10 disposed between the supporting member 17 and the shaft...

AI Technical Summary

Problems solved by technology

[0005] 1. Difficulty in assembly: During assembly, the shaft tube 12 needs to be pierced through the shell base 11, and then the positioning ring 10 and the top support member 17 are inserted into the shaft tube 12 to close the shaft tube 12 facing the shell base 11, the opening 120 on the bottom surface, and then the shaft sleeve 15 is tightly fitted in the shaft tube 12, and then the bearing 16 is inserted into the shaft sleeve 15, and finally the rotating shaft combined with the rotor 19 18 is inserted into the bearing 16 for the rotor 19 to rotate with the shaft 18 as the axis. There are many components to be assembled causing inconvenience in assembly.

Furthermore, when there are more components to be assembled, the centers of each component are less likely to be consistent, thus affecting the rotational stability of the rotor 19.

[0006] 2. High production cost: Due to the large number of components, multiple sets of molds are required for processing during production; and in order to ensure that the centers of each component can be consistent, it is necessary to improve the manufacturing accuracy of each component, resulting in high production costs

[0007] 3. Short service life: by figure 1 It can be seen that the shaft sleeve 15 is in a through shape, therefore, the lubricating oil between the bearing 16 and the rotating shaft 18 is likely to overflow from the bottom of the shaft sleeve 15 due to gravity, and the reduction of lubricating oil will not only affect the smoothness of the rotation of the rotor 19, but also Noisy and reduced service life
