Motor having built-in adjustable sound insulation device

Abstract

The invention relates to the technical field of motor heat radiation, and particularly provides a motor having a built-in adjustable sound insulation device. The motor comprises a shell. A built-in end cap is fixedly connected in the shell. The shell is internally separated into a left transmission chamber and a right transmission chamber by the built-in end cap in the shell. A transversely arranged rotating shaft transversely penetrates between the center position of the left side wall of the shell and the center position of the built-in end cap. According to the motor having the built-in adjustable sound insulation device, a lateral sealing cap using built-in and external fixed sealing rings is connected in the right internal threaded through hole of the shell in a threaded way, an extruding groove having the built-in elastic flexible sealing ring is arranged on the right side wall of the built-in end cap, and the gap between the external fixed sealing ring and the built-in flexiblesealing ring is changed by changing the position of the lateral sealing cap in the internal threaded through hole so that the heat radiation performance and the sound insulation performance of the motor can be changed according to the requirements.

Description

technical field [0001] The invention relates to the technical field of motor heat dissipation, in particular to a motor with a built-in adjustable sound insulation device. Background technique [0002] The rotor of the medium-sized motor is long, and the heat generated by the joint between the rotor and the stator is relatively large. The heat generated by the motor depends on the whirling wind generated by the rotor to dissipate the heat. During the working process of the medium-sized motor, the heat cannot be timely is taken away, causing the motor temperature to rise too fast. In the prior art, air cooling is often used for cooling medium and large motors. The fan used to cool the motor is installed inside the motor housing, and the air inlet and air outlet are located in similar positions, resulting in a greatly reduced heat dissipation performance. The heat dissipation efficiency is not high, and the current motor will generate a lot of noise during the heat dissipatio...
