Description

Technical Field

[0001] The utility model belongs to the technical field of motor vibration reduction, and particularly relates to a vibration reduction rubber ring and a vibration reduction motor. Background Art

[0002] An air conditioner is a device that regulates temperature and humidity, such as cooling, heating, and dehumidification. Existing air conditioners primarily consist of a refrigeration unit, a water pump, a fan, and a piping system. The terminal unit utilizes the supplied heat and cold to process the air. These components often utilize motors to achieve this function. However, existing motors generate significant vibration when installed within a housing. Conventional shock-absorbing rubber rings transmit this vibration when the motor vibrates severely, limiting their damping effect. Therefore, developing a shock-absorbing rubber ring and motor that overcome these limitations is crucial. Utility Model Content

The part of the shock-absorbing rubber ring facing the output shaft of the motor body is not compressed. After the motor body vibrates, the vibration cannot be transmitted in the centrifugal direction, and the air conditioner will not generate vibration.

[0008] The motor base and / or the motor gland is provided with a stepped limiting surface that cooperates with the shock absorber so that the shock absorber is tightly pressed between the outer wall of the motor body and the inner wall of the motor base or the motor gland.

[0012] The first notch and the third notch form a second through-hole, the second notch and the fourth notch form a third through-hole, and the second through-hole and the third through-hole form the channel.

[0013] A limiting groove is provided on at least one outer surface of the first outer panel, and a limiting protrusion is provided on the second outer panel to cooperate with the limiting groove, thereby increasing the stability of the cooperation and installation of the two.
