Description
Technical Field
The invention relates to a driven gear type flywheel built-in shock absorption and noise reduction device which can be widely applied to a gear driving type electric screw press.
Background
With the rapid development of the industry at present, more and more large-scale mechanical equipment is put into production, and great convenience is brought to our lives. However, the bigger the machine is, the vibration and noise are easy to generate during running, the vibration generated by the machine equipment aggravates the abrasion of the machine equipment, and the service life of the machine equipment is shortened; noise generated by machine equipment affects working environment of workers, endangers hearing health of the workers, and even affects normal life of surrounding residents in some cases.
In the working process of the existing gear-driven electric screw press, power is transmitted through gear transmission, and a driven gear type flywheel can generate sound waves to form noise as long as little vibration energy exists, so that strong impact vibration and noise damage can be generated, and the damage to an operator and the surrounding environment is great. We need to take necessary measures to solve these problems.
Disclosure of Invention
The invention aims to provide a driven gear type flywheel built-in shock absorption and noise reduction device with sound insulation, noise reduction, shock absorption and buffering functions.
In order to achieve the purpose, the shock absorption and noise reduction device internally arranged in the driven gear type flywheel comprises a driven gear type flywheel provided with a stepped hole, a plurality of convex nitrile rubber blocks arranged in the stepped hole of the driven gear type flywheel, and a pressing plate which is placed on the top surface of the convex nitrile rubber blocks, fastened with the convex nitrile rubber blocks through rubber block fastening bolts and fixed on the driven gear type flywheel through flywheel bolts.
The invention relates to a driven gear type flywheel built-in shock absorption and noise reduction device, which has the working principle that: noise prevention measures are taken for local noise sources of the gear-driven electric screw press, and a built-in shock-absorbing noise-reducing nitrile rubber block is adopted to isolate and seal the noise sources so as to prevent the noise from spreading outwards through a solid. The novel structure of the convex nitrile rubber block arranged in the flywheel is adopted, so that the noise source is fundamentally controlled and reduced. The convex nitrile rubber block has good damping performance, and can convert sound energy into heat energy to be consumed through intermolecular motion friction under the action of sound waves; the sound insulation capacity of the convex nitrile rubber block for sound waves comprises an absorption part and a radiation part, and the sound insulation performance of the material is improved by absorbing and radiating sound energy. And the convex nitrile rubber block has the characteristics of oil resistance, heat resistance, flexibility, wear resistance, buffering and damping, aging resistance, strong interchangeability, high surface wear resistance and corrosion resistance. Therefore, the convex nitrile rubber block plays roles of sound insulation, noise reduction, shock absorption and buffering.
The driven gear type flywheel built-in shock absorption and noise reduction device adopts the flywheel built-in shock absorption and noise reduction device, can reduce the vibration of the flywheel, inhibit the generation of noise, block the transmission of the noise, has good noise reduction effect and is easy to install. The invention starts from the flywheel vibration source and fundamentally reduces the noise by reducing the amplitude of the vibration source. The invention consumes a part of vibration energy by a friction energy consumption method in damping vibration reduction, thereby achieving the purpose of vibration reduction and noise reduction.
In conclusion, the driven gear type flywheel is internally provided with the shock absorption and noise reduction device, so that the sound insulation and noise reduction and the shock absorption and buffering are realized.
