External Involute Spline is a reliable and strong component in the power transmission system. Its tooth profile is involute, which is formed in the same way as involute spur gears or helical gears. The short and evenly distributed tooth profile makes it have higher strength and more uniform load distribution, which can effectively transmit torque. It is also a widely used spline shaft type due to its self-centering characteristics, high structural strength and easy adjustment of various parameters.

What types of external involute splines are there?
There are three main types: large diameter involute splines, rounded root involute splines, and flat root involute splines. Large diameter involute splines have specific size requirements when mating; the male and female parts of rounded root involute splines mesh along the circumference; flat root involute splines are similar to rounded root types, but are suitable for short-term use scenarios to maximize strength.
What materials are the products made of?
Carbon steel or stainless steel is usually used because of its high strength and durability. In certain cases, materials such as carbon fiber and titanium are also used to manufacture drive shafts, but their application is limited due to the difficulty of machining internal grooves. Materials such as aluminum, brass, bronze or plastic are also used in special application scenarios.
How to ensure the manufacturing accuracy of splines?
Manufacturing accuracy depends on many factors, including advanced processing equipment, mature manufacturing processes (such as hobbing, gear shaping, etc.) and strict quality inspection processes. Cooperating with a professional and qualified gear manufacturing factory and selecting the appropriate cutting method according to the spline tolerance requirements can effectively ensure accuracy.
