Helical Gears

The company manufactures durable and highly efficient helical gears upto 5000 mm od 50 module in cast iron & steel (single, double & multi starts) for cranes, material handling equipment, for cement plants, sugar plants, chemical plants and mineral processing plants, coal handling equipment, steel rolling mills & petrochem sectors

Helical gears connect parallel shifts but the involute teeth are cut at an angle to the axis of rotation. Two mating helical gears must have equal helix angle but opposite hand. They run smoother and more quietly. Helical gears have higher load capacity, are more expensive to manufacture and create axial thrust.Helical gears can be used to mesh two shafts that are not parallel and can also be used in a crossed gear mesh connecting two perpendicular shafts. They have longer and strong teeth. They can carry heavy load because of the greater surface contact with the teeth. The efficiency is also reduced because of longer surface contact. The gearing is quieter with less vibration.
