How are Helical Splines Made?

Helical splines are a type of machined component that has gained popularity in recent years. Originally used mainly in the aerospace industry, helical splines can now be found in a wide variety of applications. But how are they made? Let’s take a closer look.

What are helical splines used for?

Helical splines are a type of mechanical fastener that is used to connect two shafts while allowing for relative movement between the shafts. The splines are typically located at the end of one shaft and are machined with a helical groove. The second shaft has a matching helical groove that is cut slightly larger than the first. This allows the two shafts to be connected while still allowing for some axial and radial movement. 

Helical splines are commonly used in automotive applications, where they are used to connect the drive shaft to the wheels. They are also used in power transmissions, where they are used to connect gears. Helical splines by Taizhou Chengchun Automation Equipment Co., Ltd. offer several advantages over other types of mechanical fasteners, including increased strength and lower costs.

How are they made?

Helical Splines are made by a process of cutting and grinding. This type of spline is used in many industries, including automotive and aerospace. The manufacturing process begins with a blank piece of metal that is cut to size. Next, the metal is placed in a lathe where it is cut into the desired shape. Once the helical spline has been cut, it is then ground down to create a smooth surface. Finally, the spline is ready to be used in its intended application.

The benefits of using helical splines

Helical splines are a type of mechanical fastener that can be used to join two pieces of metal together. 

Unlike traditional threaded fasteners, helical splines do not rely on friction to stay in place. Instead, they are designed to interlock with the threads of the bolt, creating a strong mechanical bond. This design provides some benefits over traditional threaded fasteners. 

  • First, it allows for a more even distribution of load, meaning that the joint is less likely to fail under stress. 
  • Second, the lack of friction makes it easier to disassemble the joint, which can be useful for repairs or maintenance. 
  • Finally, helical splines are less likely to loosen over time, making them ideal for applications where a secure connection is required.

It is a machining process employed to create internal hexagonal or square slots. It is accomplished by using a rotary tool, a cutting instrument with multiple teeth along its perimeter. The tool is placed inside the Jacobs Chuck or similar tool and then rotated at high speed.

Why you should consider using them in your next project?

Helical splines use a positive mechanical interlock that prevents the joint from coming apart under high loads. This makes them an ideal choice for applications where reliability and safety are critical, such as in automotive and aerospace applications. 

Helical splines are also easy to assemble and disassemble, making them ideal for applications where frequent maintenance or replacement is required. Overall, helical splines offer some advantages over traditional keyed joints, making them an excellent choice for a wide variety of applications.
