摘要: A pre-load mechanism has a self-mounting coil spring that resiliently forces pre-loading member against pre-loaded member. The an active helical-coiled portion is expandable and contractible in axial length to set the force mounting interference fit with for allowing be by forced positioning of on calibrated position, once been so set, maintaining position as expands contracts length. non-circular helical convolutions protruding lobes bear
