摘要

The spindle-type press has a flywheel and a screw drive mechanism to which a clutch ram and a clutch plate forming the ram piston are coupled. Friction blocks are fitted in recesses in a support between the flywheel and clutch plate. Bushes of elastic material are fitted in the support recesses, bearing on the outside against the surrounding portions. The blocks are a close fit in the bushes, which can be of plastic such as polyurethane or polytetrafluoroethylene. The recesses and bushes can form elongated holes, and the blocks can be of corresp. shape. ADVANTAGE - Longer life of blocks and support.
