Gasket plays a role in preventing looseness in machinery and equipment, and gasket is a key component to ensure the stable and safe operation of machinery and equipment. Gasket plays a key role in relieving vibration and impact in machines and equipment. Gasket can also form a sealing layer at the joint to prevent liquid or gas from leaking, and at the same time prevent the joint from loosening, so as to keep the machinery and equipment in good operation. One of the main functions of the gasket is to increase the contact area. In order to ensure the connection between the screw and the object more firmly, the gasket is introduced to increase the contact area between the screw and the connected object. This not only improves the stability of the connection, but also reduces the pressure on the contact surface, thus reducing the damage to the two components connected by the screw and prolonging the service life of the components.
