Spring mounting for rotational vibration damper - has end faces of coil spring with flats facing supports and with preformed coil to fit into curved slot

摘要

The two sections of the rotational damper are braced on each other by coil springs (12) in curved slots. Each coil spring is shaped to fit the slot shape and has the end turn on each end flattened. This provides a thrust surface for the support faces and transfers the spring force at right angles into each section. One end has a double support face to grip the coil evenly while the other end has a narrow support strip in the centre of the coil. The coil is compressed without a twisting action. ADVANTAGE - Improved damping, non twist support for spring, longer life spring.
