Multidirectional vibration and noise reduction motor base

Abstract

The invention discloses a multidirectional vibration and noise reduction motor base which comprises a carrier plate, a base body and a connecting seat. Bolt holes are formed in the carrier plate. Thebase body is fixed to the bottom of the carrier plate and is composed of a first seat body at the upper portion and a second seat body at the lower portion. A recessed cavity is formed in the top of the base body, the second seat body extends into the recessed cavity, a first vibration reducing spring is connected between the side face of the second seat body and the recessed cavity, and a secondvibration reducing spring is connected between the bottom face of the second seat body and the bottom wall of the recessed cavity. A shell wall of the base body is formed by compounding three steel plates arranged at intervals, and multiple rubber balls are embedded among the adjacent steel plates. By arranging the first vibration reducing spring and the second vibration reducing spring between the connecting seat and the base body, multidirectional vibration reduction can be performed, and a vibration reduction effect can be improved. The steel plates are matched with the base body made of the rubber balls and can be matched with the first vibration reducing spring and the second vibration reducing spring in use to achieve multi-step vibration reduction, and meanwhile the multidirectionalvibration and noise reduction motor base also has a noise reduction effect.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor base with multidirectional vibration reduction and noise reduction. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function The function is to convert mechanical energy into electrical energy. [0003] Since the physical structure of the motor rotor is not completely center-symmetric and axisymmetric, the imbalance of the moment of inertia during rotation will cause vibration. The vibration situation changes according to the rotation speed. For example, the vibration is small at low speed and large at high s...

Therefore, the motor needs to be equipped with a shock absorbing mechanism to ensure normal operation, but most of the existing motor shock absorbing mechanisms can only perform longitudinal shock absorption, and the shock absorption effect is poor
