Top Helical Gear Manufacturers in Ahmedabad, Gujarat, India. When it comes to high-performance power transmission, Helical Gear stands out as a versatile and reliable choice. Manufactured by Pre-Tech Industries, these gears are designed to provide smooth, quiet, and efficient operation across a wide range of industrial and automotive applications. What is a Helical Gear? A Helical Gear is a type of cylindrical gear with teeth cut at an angle to the gear’s axis, forming a helix. Unlike straight-toothed spur gears, the angled design allows teeth to engage gradually, reducing vibration, noise, and shock loads. This unique tooth configuration also increases load capacity and ensures durable, reliable performance. How Helical Gears Work The meshing process of Helical Gears is progressive. Contact starts at one end of the tooth and moves along the tooth length as the gears rotate. This rolling engagement distributes the load across multiple teeth, enabling higher torque transmission while maintaining smooth operation. However, the angled teeth generate axial thrust, which requires proper bearings to absorb the force. Types of Helical Gears • Single Helical Gears: Ideal for parallel shaft applications; produce axial thrust that requires thrust bearings. • Double Helical (Herringbone) Gears: Teeth slope in opposite directions to cancel axial thrust, ensuring ultra-quiet and smooth operation. • Crossed-Axis Helical Gears: Suitable for non-parallel, non-intersecting shafts, often at 90° angles, ideal for specialized machinery. Technical Specifications • Material: High-grade steel alloys • Tooth Form: Involute helical teeth • Helix Angle: 15°–30° (customizable) • Module: Normal or radial module systems available • Surface Finish: Hardened and precision ground • Efficiency: 90–99.5% • Custom Options: Single, double, or crossed-axis configurations Tested Performance Pre-Tech Industries’ Helical Gears undergo rigorous testing for torque capacity, noise levels, and durability. High-speed rotation trials demonstrate reduced vibration and axial thrust absorption when paired with thrust bearings, ensuring longevity in demanding industrial environments. Built for Industry Professionals Whether for engineers, industrial operators, or automotive technicians, our Helical Gears deliver unmatched reliability. Designed for continuous operation, they excel in machinery requiring high torque, low noise, and precision motion control.
