STAND FOR CALIBRATING DRIVES Russian patent published in 1994 - IPC

FIELD: test equipment. SUBSTANCE: output shaft of calibrated drive is spring-loaded by torque by means of two-position crane 2. Piston 15, provided with rod 16 and rest 17, moves to top position. Tooth-type coupling clutches driving shaft 3 with output shaft of calibrated drive 1. Rotary motion from calibrated drive 1 is converted into translational motion of bushings-sliders 6 and 12 relatively motionless rod 9; tooth-type coupling 2, driving shaft 3, pulley 4 and elastic thread 5 are used for the purpose. After that cylinder 21 operates - piston 19 and rod 20 of the cylinder acts on brake 18, which brakes pulley 4. Order of priority of operation of cylinders 14 and 21 is provided by restrictor 23. EFFECT: improved precision. 1 dwg
