Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transmission equipment technology, specifically relating to a vibration-damping and noise-reducing mechanical transmission component. Background Technology
[0002] Currently, motors generate vibration and noise during operation, which can have various negative impacts on mechanical transmission systems. Vibration disrupts the smooth transmission of force during mechanical processes, causing fluctuations in the transmission system's operation. This makes it difficult for machining equipment to maintain precise processing parameters, severely affecting product quality. Furthermore, vibration causes minute changes in the relative positions of transmission components. In high-precision machining and transmission scenarios, these positional deviations accumulate and amplify, ultimately failing to meet the stringent precision requirements of production processes and reducing service life. The noise generated during motor operation not only pollutes the working environment for operators but also damages their hearing health with prolonged exposure to high noise levels. It also limits the use of motors in noise-sensitive applications. Summary of the Invention
[0003] The purpose of this invention is to address the above-mentioned problems by providing a shock-absorbing and noise-reducing mechanical transmission component.
