Racks - square with helical gearing
G&G racks with helical gearing are made from steel C45 and 16MnCr5. The material cross-section is square. The teeth are milled, hardened and ground – the pressure angle is 20°, the helix angle is 19°31‘42‘‘ and the toothing quality is 6h25.
Helical gear racks
Square cross-section. Design with helical gearing, hardened and ground.
Compared to drives with spur gearing, drives with helical gear racks are characterised by more uniform power transmission, the transmission of higher torques, running smoothness and lower noise levels along with high positioning and repeat accuracy.
