STARTING CLUTCH FOR SUBMERSIBLE PUMP

摘要

FIELD: pump engineering. ^ SUBSTANCE: clutch comprises axially aligned driving clutch member (1) and driven clutch member (2). The driving clutch member is made of screw shaft (3). The clutch members are interconnected via slide (4) connected with the driving clutch member by means of a screw joint and with the driven clutch member by means of spring-loaded movable stop (5) mounted in slide (4). The clutch members are arranged inside housing (6) provided with longitudinal unmovable stop (7). Driven clutch member (2) is made of cylindrical sleeve (8) having slot (9) inclined to the generatrix. The initial section of the slot in the cylindrical sleeve is parallel to the generatrix, and its length is no less than that of the movable stop. Movable stop (5) engages slot (9) and can cooperate with unmovable stop (7). Movable stop (5) is made of a rectangular parallelepiped. The top section of the movable stop has side groove that cooperates with the bottom edge of slot (9) in the cylindrical sleeve. ^ EFFECT: expanded functional capabilities. ^ 5 cl, 5 dwg
