What is the purpose of a spline?
Splines are ridges or teeth on a drive shaft that mesh with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.
What is the spline on a clutch?
Clutch Splines. At the rear of the engine, fastened to the end of the crankshaft (or output shaft, on K models) is the clutch carrier, or clutch housing. The hub of the clutch disc has splines that drive the input shaft of the transmission. The splines allow the disc to center itself between the clutch plates.
What are splined couplings?
Spline couplings are mechanical components used to connect and transmit torque between two rotating shafts. A spline coupling consists of two parts: a shaft with external teeth and an hub with internal teeth; the load is transferred from the shaft to the hub (or vice-versa) by means of a number of engaging teeth.
What is the difference between a gear and a spline?
Splines and gears are both purposed to transmit torque and both feature external teeth that lock into place with a mating component. Splined shafts differ from gears as they use all teeth or grooves simultaneously to transfer torque. Gears in contrast, utilize one tooth at a time to transfer torque.
Why are splines used on shaft?
Is the spline necessary?
When used on a miter joint, the spline adds extra strength to an otherwise delicate joint. The spline is also useful because it helps to align the two joining parts during assembly and glue-up. For extra strength, the grain direction of the spline can run at 90° to the grain of the boards.
Should I grease clutch splines?
Lightly grease the hub spline of the clutch disk and the transmission input shaft. If too much grease is used, centrifugal forces will transfer it onto the clutch linings during operation. Linings soiled in this way will cause the clutch to grab or chatter during operation.
Where are splines used?
Heavy Machinery: Spline shafts are frequently used in automobiles, aviation, and earth moving machinery as they can handle high rotation speeds to deliver torque. Unlike alternative shafts like key shafts, spline shafts can deliver more torque due to the even distribution of the load across all the teeth or grooves.
How are splines machined?
The splines are cut into the shaft by a process called straddle milling. The indexing fixture holds the shaft of the spline steady while a groove is cut by the rotating milling cutters along its length. Depending on the depth of the spline, multiple passes along the same groove may be needed.
How do splined connections fail?
Spline teeth are usually sized and fail in the following ways: spline tooth shear stress, compressive stress on the flanks of the teeth, bursting stresses, and torsional-shear stresses of the shaft or supporting structure.
Are splines interchangeable with gears?
A splined shaft is designed to transmit torque. A splined shaft can come with square-sided or triangular splines, while the teeth of a gear can have curves. Because of this, the usage of splined shafts and gears are not always interchangeable.
