The spring cushion ring is widely used in the support and non -inheritance structure of general mechanical products. It is characterized by low cost, convenient installation, and suitable for frequent parts of disassembly.However, the anti -pine capability of spring cushions is very low! Especially in the current requirements of high -reliability products in Europe and the United States, the use rate is extremely low, especially the important bearing structure connection parts have long been abandoned for many years.
Spring cushion ring opening direction
As long as it is a clockwise locking bolt, the spring pad is in the direction of preventing loosening. Unless you use anti -tooth bolts, the spring pads are used casually, it is impossible to be reversed! Because the screws are twisted right, soIf you speak to the right, tighten the screws if you open your mouth to the right, and it will produce a relatively large friction force, which is not easy to be tight.
Spring cushion material
65mn spring steel or 70#carbon steel is usually used, but sometimes 60sI2MN can also be used, and stainless steel material SUS304 or SUS316 can also be used.
The role of spring cushion
The spring cushion ring is widely used in the support and non -inheritance structure of general mechanical products. It is characterized by low cost, convenient installation, and suitable for frequent parts of disassembly.However, the anti -pine capability of spring cushions is very low! Especially in the current requirements of high -reliability products in Europe and the United States, the use rate is extremely low, especially the important bearing structure connection parts have long been abandoned for many years.Our country has some applications in military industry, but it has been improved to stainless steel materials.It is said that the steel spring cushion ring has been banned in CASC! It is also said that it is very unsafe, because two 1 is the "rising circle" 2 is hydrogen and gruel.
Spring cushion specification
The specifications of the spring cushion ring of the flat pads are: 200 ~ 300HV and 300 ~ 400HV.Disan -shaped spring cushion rings are generally commonly used specifications in M3, M4, M5, M6, M8, M10.m12, M14, M16.In order to insert the opening of the opening to insert the opening of the screw from the nut of the nut, it is mainly used to prevent the thread from loosening.
