Title: Laminated disc spring
Inventor: MIKURA MASAAKI
IPC: F16F1/32
Filed: 2002-06-14
Abstract: PROBLEM TO BE SOLVED: To materialize a load-displacement characteristic with small hysteresis in a laminated disc spring laminated in parallel. SOLUTION: A plurality of disc springs 10 are laminated in parallel. The surface roughness of the contact surface of respective disc springs 10 is set within the range from Rmax 1.0 or more to 2.0 or less. A dissimilar material layer is provided between respective disc springs 10.
