BED FOR TESTING GEAR TRANSMISSIONS Russian patent published in 1994 - IPC

FIELD: testing equipment. SUBSTANCE: bed for testing of gear transmissions in accord with circuit of closed loop has base, main drive, two differentials which bodies are installed on base for turning and carrier of each of them is rigidly connected to body, supplementary drive coupled to body of one differential and measurement device coupled to body of second differential. Novelty of bed lies in manufacture of differentials in the form of planetary gears with cylindrical gear-wheels and two-ring satellite gears having different number of teeth in ring. Analogous shafts of differentials are interconnected, the other analogous shaft of differentials are linked to closing circuit of bed. EFFECT: simplified design of bed, improved conditions for taking measurements of load parameters and for inspection of quality of tested transmissions. 3 cl, 2 dwg
