Understanding the Spline Gear that is Splined to the Input Shaft
Which Gear is Splined to the Input Shaft?
The gear splined to the input shaft is the spline gear. The spline gear is a mechanical device that transfers power from the input shaft to the output shaft in a machine. The splines on the gear mesh with the splines on the shaft, creating a non-slip grip that allows for the transfer of torque.
Our Quality Spline Shaft Production
We take pride in manufacturing high-quality spline shafts. Here are five features that set our products apart:

Different Types of Spline Shafts and Their Features
Parallel Key Shaft
The Parallel Key Shaft features parallel splines that ensure a secure connection between components, resulting in efficient power transfer.
Spline Shaft with Involute Spline
A Spline Shaft with Involute Spline provides an even distribution of load across the entire shaft, making it perfect for high-torque applications.
Internal Spline Shaft
The Internal Spline Shaft has its splines on the inner diameter, allowing it to fit perfectly onto an externally splined shaft or gear.
Non-circular Spline Shaft
The Non-circular Spline Shaft is designed for specific applications where the load needs to be distributed in a non-uniform manner.
Selecting the Right Spline Shaft
When choosing a spline shaft, you need to consider the following parameters:
- Shaft Diameter
- Spline Type
- Number and Size of Splines
- Shaft Length
- Material
- Surface Treatment

Manufacturing Process of Spline Shafts
The manufacturing process of spline shafts involves several steps:
- Material preparation
- Cutting
