What is an involute spline?
A spline is a set of narrow generated longitudinally around the circumference of a shaft or grooves generated on the inside bore of a workpiece. The externally splined shaft mates with an internal spline that slots, or spaces, formed in the reverse of the shaft’s teeth.
How do you create an involute spline?
Design involute splines
- On the ribbon, click Design tab Power Transmission panel Involute Splines .
- On the Design tab: Click the arrow next to the Splines Type edit field to select the spline. Enter the spline dimensions. Specify the position of a shaft groove.
- Select OK.
What is an involute serration?
Involute Splines: Types, Design Considerations, Materials, and Applications. Splines are driven shafts that work by interlocking the grooves of one piece with the teeth of a mating bushing.
How do you make an involute gear?
When drawing an involute, you draw one side of one tooth, mirror that to make a whole tooth, and that copy that around your gear the right number of times. A new involute has to be drawn for each size of gear in your system. To begin drawing, lay out three concentric circles: One at the pitch circle.
What is a serrated spline?
Straight sided serrated splines: As the name suggests, straight sided serrated splines have straight teeth rather than curved teeth. The shape of the tooth is triangular with a flat surface. Straight sided serrated splines can be used on either the internal or external surface of a driveshaft / gear.
How is an involute formed?
An involute is constructed by rolling a so-called rolling line around a base circle. The resulting trajectory curve describes the shape of the involute. Two mirror-inverted involutes then form the basic shape of a tooth. The involute can also be constructed by unwinding a string from a circle.
Why involute profile is used in gears?
An involute gear has the profiles of its teeth in the shape of an involute of a circle. This structure helps to reduce torque variation and allow greater assembly flexibility, helping to make involute gears one of the most popular power transmission devices.
What is stub pitch in spline?
stub pitch: It refers to the radial distance from the pitch circle of the external spline to the major circle and that from the pitch circle of the internal spline to the minor circle. In ANSIB92. 1, the stub pitch is two times more than the diametral pitch.
What does spline mean?
Definition of spline 1 : a thin wood or metal strip used in building construction. 2 : a key that is fixed to one of two connected mechanical parts and fits into a keyway in the other also : a keyway for such a key.
