Custom Splines, Shaft Spline and Involute
|
HM Manufacturing is a manufacturer of custom splines tailored to your specific needs. Splines are the ridges or teeth (external spline) on a drive shaft that mesh with an equal number of like ridges or teeth (internal spline) in a mating piece with the purpose of transferring torque and power to the same axis. HM Manufacturing's capabilities include the production of splined pulleys and shafts for axles, power transmission, gearboxes and other motion control applications. By utilizing different pressure angle designs of 30º, 37.5º, 45º we have the ability to produce a variety of involute, serration and straight-sided splines tailored to your specific needs. Splines from HM are manufactured from the highest quality materials, designed and engineered to meet every customer's specifications such as tight tolerances, dynamic shape dimensions, custom amount of teeth and size.
HM Manufacturing has extensive knowledge in involute, serration and straight sided splines. Using milling, shaping and broaching techniques, allows for exact configurations of the overall part requirements.
SPLINE INFORMATION:DIMENSION CAPABILITIES
Maximum Pitch Diameter – 24” Diametral Pitch – 4/8 – 80/160 Face Width – 10” Unground Tooth – AGMA Q9 Ground Tooth – AGMA Q13 What are Involute Splines?Involute splines refers to the shape of the tooth that is being formed on the spline and matching shaft. The tooth form is curved on the sides with a flat top. Involute splines can be made as external or internal. Due the the involute shape there is more surface contact between spline and shaft, which allows the spline to provide greater torque. Involute splines perform best in heavy duty applications for a variety of industries.
What are Serration Splines?Similar to involute splines, serration splines can also be made as external or internal. However the shape of the tooth is triangular and the top of the tooth is flat. Serrations splines are generally used on smaller diameter drives. Since the teeth are a simple included angle form, more teeth can be used on a small circumference, providing a greater contact area. Some example of serrations splines in use would be instrument drives and valve shafts
What are Straight Sided Splines?Straight sided splines can be made as external and internal. The tooth shape is what separates the straight sided spline from the involute and serration. In a straight sided spline, the sides of the teeth are parallel to each other, they are not curved or angled and the top of each tooth is flat, similar to a keyway shape. Straight sided splines are used in couplers and are great for the food processing and automotive industries.
