BENCH TESTING GEAR TRANSMISSIONS ACCORDING TO ARRANGEMENT OF CLOSED CIRCUIT Russian patent published in 2004 - IPC

FIELD: testing equipment, benches testing mechanical transmissions, testing gear transmissions in process of their manufacture or running. SUBSTANCE: bench testing gear transmissions according to arrangement of closed circuit has drive, input and output shafts to install drive and driven wheels of tested gear transmission correspondingly, loader coupled to output shaft and closing device. The latter includes gear transmission with drive and driven gear wheels which are put on input and output shafts correspondingly, nut. Output shaft of nut has shape of screw. Screw is mounted for axial displacement and nut is made fast to driven wheel of gear transmission of closing device and forms together with screw transmission screwnut. Gear transmission of closing device and tested gear transmission have same transmission ratio. EFFECT: prolonged service life of bench, simplified process of loading of gear transmission. 1 dwg
