Helical Gearbox – Helical gears have teeth that are oriented at an angle to the shaft. This leads to more than one tooth to be in contact during the operation, which makes the gear capable of carrying more load. Due to the load sharing between teeth, this arrangement also allows helical gears to operate smoother and quieter than spur gears. Some of the industries where the helical gears are commonly used are printing, chemical and fertilizer industries, power industries, steel, textile industries, food industries, paper and plastic industries, elevators, conveyors, compressors, blowers, and automotive industries.
