Parallel Helical Gearbox

Parallel Helical Gearbox

Parallel helical gears, the common one, is used to for power transmission between parallel shafts. Two mating parallel helical gears should have same module, same pressure angle but opposite hand of helix. They offer vibration-free and quiet operation and can transmit heavy load.A parallel gear drive is one in which the high and low speed shaft are on the same horizontal plane and parallel to each other. Parallel shaft gear boxes are usually selected for high torque and high horsepower applications.
