Backlash Control Spur Gears

What are Backlash Control Spur Gears?

Backlash control spur gears are precision-engineered rotary components crucial in moving mechanical systems. Characterised by their unique double-stacked tooth profile, these adjustable gears are designed to mesh seamlessly with other components, ensuring minimal play or 'backlash' between them. This characteristic is vital for applications requiring high precision and minimal gear slop, ensuring smooth, consistent power transmission with no dead zone.

How Adjustable Backlash Spur Gears Work.

Accu's adjustable backlash spur gears find their significance in a variety of industries, from automotive to robotics. When installed, they play a pivotal role in maintaining the integrity of the gear assembly, allowing for precise control and reduced wear and tear.

In design, the machine screws around the gear can be loosened allowing the inner spur gear to be rotated and adjusted to finely balance the amount of backlash or "play" when meshed with other components. When the perfect setting has been achieved, the machine screws are tightened back up to keep the setting in place. This adjustment offers a balance of efficiency between regular spur gears and our spring-loaded anti-backlash spur gears.

Material Composition.

Our backlash control spur gears are crafted from high-grade steel, a material renowned for its strength and durability. Steel offers the resilience needed in demanding environments, ensuring longevity and consistent performance. The choice of steel also means these gears are adept at handling high-stress applications, making them a versatile component across industries.

Sizes and Types Available.

Our range includes adjustable backlash spur gears with a pitch circle diameter from 60mm to 100mm, catering to diverse needs. The number of teeth varies from 30 to 70, allowing for a broad range of gear ratios. Bore diameters range from 12mm to 20mm, ensuring a snug fit in various assemblies. The modules (pitch between teeth) span from m1.5 to m2, providing options for different precision levels. Special finishes are available upon request via our custom manufacturing option, enhancing the gear's performance and longevity in specific environments.
