Abstract
When machine elements having a large mass are indexed, i.e. subjected to short, quick rotating movements, very great acceleration and deceleration forces must be transmitted via the driving means of the machine. Due to vibrations occurring, increasing the stresses on the driving means, the driving means must be dimensioned accordingly. The present invention provides a method and an arrangement for the compensation of the forces applied and thus for reducing the stresses which occur. This is performed by combining the indexing machine element with a cam disc which is contacted by a number of spring-loaded cam followers, whereby the cam disc has such a shape that the cam follower decelerates and accelerates the cam disc following the desired movement pattern of the machine element.
