Description

Technical Field

[0001] The utility model relates to the technical field of vibration motors, in particular to a vibration motor with good noise reduction effect. Background Art

[0002] A vibration motor is an exciting source that combines a power source with a vibration source. It installs a set of adjustable eccentric blocks at both ends of the rotor shaft, and uses the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks to obtain exciting force. As a power source for various screening machines, vibration motors are becoming more and more popular in our lives and are widely used in hydropower construction, thermal power generation, construction, building materials, chemicals, mining, coal, metallurgy, light industry and other industrial sectors.

[0003] During the use of existing vibration motors, due to the need to generate violent vibrations, large noise pollution will be generated. The noise not only poses a direct threat to the working environment and employee health, but also has a negative impact on the vibration motor itself and the equipment it drives. Continuous noise may mean that the vibration motor or related equipment has unstable operation or failure problems. Therefore, the noise generated by the vibration motor not only affects the work efficiency and health of employees, but may also cause damage to the equipment and the surrounding environment.

[0004] For example, a new type of high-efficiency vibration motor disclosed in announcement number CN220586107U does not have a noise reduction structure for the vibration motor. The vibration motor without noise reduction function will generate loud noise during operation, which will not only cause serious noise pollution to the working environment, affect the work efficiency and health of employees, but may also have an adverse impact on the surrounding environment.

[0005] Therefore, it is necessary to invent a vibration motor with good noise reduction effect to solve the above problems. Utility Model Content

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1.

[0029] The first sound insulation layer 5 can effectively block the noise generated inside the vibration motor from propagating outward, and the first sound absorption layer 6 can absorb the noise generated inside the vibration motor, thereby effectively reducing the generation of noise and the impact of noise on the surrounding environment.

[0030] The No. 1 soundproof cover 7 and the No. 2 soundproof cover 8 have the same structural design. The bottom of the No. 1 soundproof cover 7 and the No. 2 soundproof cover 8 are hingedly connected to the top of the base 1. A lock buckle 9 is arranged on the top of the connection between the No. 1 soundproof cover 7 and the No. 2 soundproof cover 8. There are two lock buckles 9.
