Types Belleville wave slotted finger curved e Spring washers.Push-Belleville has high loads and low deflections-choice of rates(constant,increasing,or decreasing). Wave has light loads,low deflection,uses limited radial space.Slotted has higher deflections than Belleville. Finger is used for axial loading of bearings.Curved is used to absorb axial end play. Volute spring.Push一 (g)Beam springs.Push or Pull- (h)Power or motor springs. (i)Constant Force. may have an inherently wide load but low deflection Twist-exerts torque over Pull-long high friction damping. range-rectangular or shaped many turns.Shown in,and deflection at low cantilever,or simply supported removed from,retainer. or zero rateTypes
