Helical gears contain teeth that are placed at an angle to the shaft, causing several teeth to be in contact during operation, and helical gears are capable of carrying a heavy load. This configuration also allows helical gears to run smoother and quieter due to load sharing between teeth. Thus, helical gears are able to generate thrust during operation, which should be taken into account when used.
2. What are the applications of Helical Gears?Generally, helical gears are used in the majority of enclosed gear drives and in applications that rewire heavy load efficiencies and noiseless functioning, especially in the automotive industry. Helical gears are extensively employed in many different industries applications such as:
-- printing, earth-moving, and fertiliser industries,
-- steel and rolling mills, port and power industries
-- textile, food, and plastic industries,
-- elevators, conveyors, compressors, blowers, cutters, and oil industries
Because each tooths width is greater, more teeth will come in contact at any given time. So, helical gears are able to transfer weights and loads more smoothly than spur gears. This results in increased load capacity, quieter operation, and faster speeds. With the increase of sliding friction between teeth and thrust loads, helical gears operate at a lower efficiency compared to spur gears.
