ABSTRACT:
An arrangement for reducing a rotational speed of a rotating member includes a first and second pressure member arranged at a distance from each other and an opposite sides of the rotating member for movement relative to each other between a retracted position and a forward position engaging the rotating member. The arrangement includes an adjustment device including a friction structure forming a friction joint with one of the pressure members for maintaining a position relative to one another provided a maximum friction force is not exceeded. The arrangement further includes a spring acting on the friction structure for separating the pressure members after having been compressed. The spring has a gradually increasing spring force between a non-compressed state and a totally compressed state. An intermediate spring force value of the spring, which corresponds to compression of the spring to an extent less than the totally compressed state, equals a maximum friction force of the friction joint so that the friction structure is forced to move relative to the pressure member, with which it forms the friction joint, when the maximum friction force is exceeded.
