Gear, by a very basic definition is the machinery or device in a vehicle that regulates the power of its engine. However, the modern and sophisticated industrial gears have surpassed the conventional gears, both in application and scope. Today, the gears are used in a multitude of applications in numerous sectors. Some of the industries in which the contemporary gears are used include aviation, cement, defense, fertilizer, food-processing, medical, railway, steel, to name a few.
Helical Gear, These are also one of the well-known types of industrial gears. The involute teeth of these gears mesh at an angle to create optimum thrust load. The name helical is due to their teeth, which are curved along a helical path or resemble a helix. Their advanced design enables a smooth operation of these gears. Not only this, they can comfortably carry heavy loads due to the enhanced surface contact with teeth.
The teeth of the helical gears are shaped in a manner to create a thrust load. These gears work exactly divergent to the spur gears. Unlike spur gears that are set parallel to the axis of rotation, They are set at an angle to the axis of rotation. Helical are used in a number of industries like rubber, steel, medical, packaging, etc.
