Embodiment Construction

[0016] The closed connection structure and assembly method of the plastic-sealed motor end cover of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 2 As shown, the closed connection structure of the plastic-sealed motor end cover includes a rotor including a plastic-sealed stator and its two end covers, a press-in shaft and a bearing. The end cover 1 on one side of the plastic-sealed stator is connected to the plastic-sealed stator 2 An integrated plastic-sealed end cover 1, the end cover on the other side of the plastic-sealed stator is a sheet metal end cover 4, and the insides of the two end covers 1 and 4 respectively contain the bearing 5' and another bearing 7.

[0018] The shape of the plastic-encapsulated end cap 1 and the sheet metal end cap 4 are the same, and the sheet metal end cap 4 is embedded in the groove 8 of the plastic-encapsulated stator 2 . Its purpose...

Abstract

The invention discloses a new connecting structure and assembling mode for a plastic packaged motor end cover, comprising: a plastic packaged stator and an end cover packaged together with the stator at one end and a metal plate end cover at the other end, where each end cover contains a bearing room. And the assembling mode: firstly assembling a rotor pressed in a bearing on one side of the plastic package, and then inserting the metal plate end cover into the groove of the plastic packaged stator. And it reduces production cost and assures concentricity of the bearing rooms, reducing noises of motor.

Description

technical field [0001] The invention relates to a plastic-sealed motor end cover structure, in particular to a plastic-sealed motor closed-end cover connection structure with low noise and tight fit between the end cover and its bearing chamber. Background technique [0002] The plastic-encapsulated motor is mainly suitable for the indoor unit side of the air conditioner split unit, and has strict requirements on noise. The main structure is composed of a plastic-encapsulated stator, a rotor, and an end cover matched with the frame of the indoor unit. This structure is mainly used to reduce noise, reduce vibration, and save materials. [0003] Commonly used plastic motors figure 1 structure shown. Such as figure 1 As shown, it includes a plastic-encapsulated stator, a rotating shaft rotor that maintains a certain air gap with the stator, and a sheet metal end cover that fits tightly with the grooves on both sides of the stator. The inside of the end cover is provided wit...
