20Cr2Ni4 Parallel Spline Driven Shaft

Customized Alloy Steel 20Cr2Ni4 Spline Grinding Parallel Spline Driven Shaft

1) Types of Splined Shaft

Splined shafts are available in a wide assortment of designs, depending on the shape, space, and size

of the grooves and keys on the shaft and mated components.

a) Parallel key splined shaft

Parallel key splined shaft designs feature square-shaped keys and grooves with profiles that run

parallel to the shaft’s axis. This design is ideal for load-bearing applications that require smooth motion.

b) Involute Splined Shaft 

This type of splined shaft decreases stress on the shaft by using tapered keys and ridges.

Involute splines are typically used in high speed and high stress applications for better torque and

reduced potential for slippage or misalignment.
