Turner Powertrain precision gears and drive shafts are manufactured to very high precision and tight tolerances to maintain consistent quality.
The gears are of a helical design. Helical gear teeth allow the design of finer more closely spaced teeth and individual tooth is elongated to provide a greater contact surface than the alternative straight cut gears. Helical gears are designed to allow gear engagement across three teeth at any one time.
This multiple tooth engagement spreads the load across the gear teeth which reduces wear and extends gear tooth life. A second benefit is a reduction in noise.
