Helical Gear

Understanding Helical Gears: Smooth & Strong

Helical gears are cylindrical gears with teeth set at an angle (helix angle) to the gear's axis of rotation. Unlike spur gears where teeth mesh along their entire face simultaneously, helical gear teeth engage gradually, starting at one end and progressing across the tooth face. This results in:

• Smoother Operation: The gradual engagement reduces impact and vibration, leading to quieter running.
• Higher Load Capacity: More teeth are in contact at any given time compared to spur gears of similar size, distributing the load over a larger area and allowing for higher torque transmission, making them suitable as high-load-gear components.
• Higher Speed Capability: Reduced vibration and smoother meshing enable operation at higher peripheral speeds.
• Axial Thrust Generation: A consequence of the angled teeth is the generation of an axial force (thrust) along the gear shaft, which must be accommodated by appropriate bearings (e.g., thrust bearings).

Key Characteristics:

• Helix Angle: The angle between the tooth trace and the gear axis, typically ranging from 15° to 45°.
• Hand of Helix: Gears can be right-hand (RH) or left-hand (LH). Parallel shafts require opposite-hand gears, while crossed shafts (screw gears) can use same-hand gears.
• Applications: Widely used in automotive transmissions, industrial gearboxes, machine tools, and various power transmission systems where smooth, quiet operation and high load capacity are essential. We provide ahmedabad-gears for these diverse applications.
