Explosion-proof pneumatic intermittent rotating device

摘要

The pneumatic intermittent rotating device has claws (19a,b) provided on a piston (4) and moved in accordance with the reciprocating movement of the piston by utilising pneumatic pressure. A spindle (6) is turned intermittently by the claws. The claws consist of a pair of claws, which are selected by a change-over lever (21) so that only one of them causes the spindle to be intermittently turned. The rotational direction of the spindle is switched by a selecting operation of the change-over lever.
