Description

Technical Field

[0001] The utility model relates to an elastic piece, in particular to a novel wave spring. Background Art

[0002] In the modern industrial field, wave springs are widely used in various precision machinery, automation equipment, automotive parts and electronic devices due to their unique structural advantages, such as compactness, high load-bearing capacity and good force distribution characteristics. Although traditional wave springs perform well in terms of space utilization and load bearing, in certain specific application scenarios, especially when frequent disassembly, maintenance or dynamic load environments are required, the friction, wear and installation stability between the end face and the contact parts become the key factors limiting their performance.

[0003] To solve the above problems, technicians have tried to add gaskets to both ends of the wave spring, hoping to reduce end face wear and improve installation stability by increasing contact area and improving friction interface. However, in the prior art, unfixed gaskets are prone to displacement during long-term use or in a vibrating environment, which not only affects the normal operation of the spring, but may also cause safety issues. At the same time, for application scenarios that require regular inspection or replacement of gaskets, there is a lack of a convenient disassembly and reinstallation mechanism, which increases the difficulty and cost of maintenance.

[0004] Therefore, developing a new structural design that can ensure that the gasket is firmly set on the end face of the wave spring and can be removed and replaced has become a technical challenge that needs to be solved urgently. The ideal solution should take into account the reliability of the gasket's fixation and the flexibility of operation, while maintaining or improving the performance indicators of the original wave spring to meet the growing market demand for high performance, long life and easy maintenance.
