CLUTCH

FIELD: mechanical engineering. ^ SUBSTANCE: clutch comprises inner member (1), outer member (2), and wedging bodies made of rods (3) and interposed between the members. Outer member (2) is made of a hollow cylinder provided with locking rings (4) and (5) set in the ring grooves provided at the end sections of its space and ring collar (7) provided in the intermediate section of the space. Inner member (1) is made of end sleeve (8), inner sleeve (9), and floating disk (10) that is mounted for permitting movement along pin (11) of internal sleeve (9). End sleeve (8) and inner sleeve (9) are mounted in the space of outer member (2) by means of centering collars. Inner sleeve (9) is mounted for permitting axial movement between locking rings (4) and (5) of outer member (2) by means of prismatic keys. The faces of the sleeves interact one with the other by means of three rods (3) interposed between the faces and mounted in ring groove (14) provided in end sleeve (8) and oval recesses (15) provided in inner sleeve (9). Each of rods (3) is mounted in ring groove (14) of end sleeve (8) and oval recesses (15) of inner sleeve (9) by means of ball pivots (16), axles (17), and shaped threaded bushings (18). The outer face of end sleeve (8) is provided with ring (20) to define a slide bearing. Ring (20) cooperates with locking ring (4) of outer member (2) through stop ring (21). Inner sleeve (9) receives three spring-loaded rods mounted in through cylindrical openings. One end of the rod cooperates with the bottom of ring groove (14) in end sleeve (8) or the stop in ring groove (14). The other end of the rod is set in the opening of floating disk (10). The rod has a cylindrical hollow, and the end of the rod set in the opening in floating disk (10) has thinning and adapting chamfering. Each flexible member made of cylindrical compression spring cooperates with the bottom of the cylindrical recess in the rod and cylindrical hollow in the face of floating disk (10) by its end turns. The ring groove in floating disk (10) receive segments (32) to lock inner sleeve (9) in operation position. The end of the rod cooperates with the inner cylindrical surface of segment (32) or the chamfering of the thinning. The ring collar of inner sleeve (9) is provided with trapezoidal groves that receive the segments and flexible members. The groove of each segment embraces the prismatic key. The keys are set in key grooves provided in outer member (2) between centering collar (12) of end
