Product RoleApplication Scenarios
The spline shaft plays a critical role in heavy-duty power transmission systems. Its multiple-tooth engagement significantly enhances load capacity while maintaining compact dimensions, enabling the transmission of high torque without compromising alignment or precision.
Rectangular splines offer uniform stress distribution for excellent centering accuracy, while involute splines provide automatic precision self-centering, ensuring zero-backlash power delivery and high positioning accuracy.
It is perfectly suited for applications requiring both high-speed rotation and controlled axial movement, such as gearbox shifting mechanisms and robotic arm extension systems.
