TEST STAND FOR COAXIAL REDUCTION GEARS Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to design of test stands and it can be used for testing coaxial reduction gears in closed circuit. Proposed stand contains drive motor 3 and two coaxially installed reduction gears 1 and 2. Hollow output shafts 7 and 8 are interconnected by flexible coupling 9. Input shafts 4 and 5 arranged inside hollow shafts are connected by coupling 6. Housing of reduction gear 1 is installed stationarily on frame 10of stand, and housing of reduction gear 2 is installed in process support 11 secured on frame 1 for turning through preset angle relative to housing of reduction gear 1. Worm self-braking pair 12 is installed in support 11 to turn housing of reduction gear 2 through preset angle and fixing it in position. Worm wheel of pair can be made in form of sector secured by screws on housing of reduction gear 2. Any mechanical or hydraulic device installed on process support can be used instead of worm pair.

EFFECT: improved testing.
