Spring washer (spring washer)
The main function is to prevent loosening. Its unique wavy structure is compressed after the bolt is tightened, generating a reverse elastic force that can effectively prevent the nut from loosening due to dynamic loads such as vibration and impact during equipment operation. For example, in some high-speed mechanical equipment such as fans, motors, etc., the anti loosening effect of the spring pad is crucial to ensure that the connection parts of the equipment remain stable at all times, avoiding faults and safety hazards caused by looseness.
The anti loosening effect of the elastic pad is closely related to its elastic deformation ability, which requires certain installation space and sufficient compression space between the connected parts to achieve its optimal performance.
