Japanese Patent JPS4964766
Kind Code:
A
Abstract:
This worm gear device is intended for driving an output shaft at a relatively low speed while reducing very considerably the radial stress due to teeth meshing reactions in order to preserve a maximum capacity of the driven shaft bearings and absorb stress due to the flexion moments applied to the driven shaft. It comprises a main reduction gearing with two diametrally opposed driving worms both meshing with the single driven wheel and each driven in turn by a primary reduction worm gearing having its driven wheel coupled to the shaft of the corresponding worm of the main reduction gearing, the cases of said two primary worm gearings being mounted for free movement but interconnected by a reaction bar pivoted at its end, the input shafts of the two primary reduction gearings being furthermore interconnected by coupling means capable of accomodating a relative angular misalignment between these two shafts.
