High-precision gears - These are gears that are manufactured to tight tolerances and with high-quality materials. They may include helical gears, bevel gears, or planetary gears.
Stiff housing - The gearbox housing is designed to be rigid and to resist any deformation or bending that might introduce play in the gears.
Preload mechanisms - These are devices that apply a small amount of pressure to the gears, keeping them in contact with each other and reducing the amount of free movement.
Anti-backlash devices - These are devices that help to eliminate or reduce the amount of free movement in the gear train. They may include spring-loaded mechanisms, adjustable shims, or other mechanisms.
Low backlash gearboxes can offer several advantages over traditional gearboxes, including improved accuracy, repeatability, and reliability. They can also help to reduce noise and vibration in the power transmission system, leading to smoother operation and longer component life.
