Typical application scenarios of helical gears
Dec 26,2025
Automotive transmission system
Transmission: Manual/automatic transmissions widely use helical gears to achieve smooth shifting and reduce jerking. For example, in the Toyota Aisin 6-speed automatic transmission, the proportion of helical gears exceeds 80%.
Differential: The transfer case of four-wheel drive vehicles distributes power to the front and rear axles through helical gears, balancing torque and reducing noise.
Power steering system: The helical gear converts the rotation of the steering wheel into linear motion of the steering rack, improving steering accuracy.
Industrial gearbox
The helical gear reducer is widely used in:
Metallurgical equipment: scenarios that require high torque transmission, such as blast furnace winches and continuous casting machines.
Lifting machinery: the lifting mechanism of tower cranes and gantry cranes.
Conveyor equipment: Drive devices for belt conveyors and screw conveyors.
High end manufacturing field
CNC machine tool: The spindle box adopts helical gear transmission to ensure stability during high-speed cutting.
Robot joint: The helical gear structure in the harmonic reducer achieves high-precision motion control.
Aerospace: The landing gear retraction mechanism and control surface drive system of aircraft use helical gears to transmit power.
