What is a 16 32 spline?
If we had a 16/32 spline, the pitch of the spline would be 16 (16 teeth on a 1.000″ pitch diameter), and the addendum would be 1/32″ (. 031″). These type of splines are said to have stub teeth. In order to change the pitch diameter you must change the number of teeth or the pitch.
What is a standard spline?
Typical involute SAE/ANSI spline teeth are specifies as two numbers: a numerator that specifies the tooth thickness in diametral pitch (DP) and the second number that specified the tooth height in diametral pitch (DP). Thus an 8/16 spline has the tooth thickness of 8 DP and a tooth height (whole depth) of 16 DP.
What is a shaft spline?
Definition of spline shaft : a splined shaft specifically : one having a number of equally spaced grooves cut in the shaft so as to form a series of projecting keys and fitting into an internally grooved cylindrical member.
How do you calculate involute splines?
The Y = 1.5 value is used in the calculation….Compressive stresses on sides of spline teeth.
| Calculated spline length | L f = min {L, Le} [in] |
|---|---|
| Depth of teeth engagement h h ≅ 0.9 / P [in] | for splines with flat groove bottom |
| h ≅ 1 / P [in] | for splines with filleted groove bottom |
What does involute spline mean?
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. Involute splines are the predominant form of splines because they are stronger than straight sided splines and are easier to cut and the fit. …
How are splines designed?
It transmits torsion, but permits axial sliding. The current practice for designing splines to carry a torque is to use involute splines with no helix angle or taper on the external tooth. In preliminary design, all teeth of the spline are assumed to carry an equal amount of load.
How do you calculate spline modules?
a spline for a 50mm OD spline with say a module of 2mm would have a PCD (D) of 50 – 2 = 48mm. The number of teeth = D/m and as an whole number of teeth is required a value of D = 48mm is easily selected with number of teeth z =24 teeth.
What are the advantages and disadvantages of involute splines over straight sided splines?
Compared to straight-sided (i.e., parallel) splines, involutes splines offer several advantages, including: Simpler design, which allows for easier—and thereby cheaper—manufacturing operations. Greater contact area along the tooth profile, resulting in smoother operation. Higher tolerance for misalignment.
Are more splines better?
Higher spline counts gives the axle more surface to transfer the load of the torque from the differential. There is also the side advantage that an axle with more splines will also be physically bigger. At least in most modern axles that use similarly sized spline teeth.
