How do you create a spline?
A spline is a geometric feature used to join one shaft to another. 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.
How do you dimension a spline in Solidworks?
Click Smart Dimension (Dimensions/Relations toolbar) or Tools > Dimensions > Smart. Select the spline to display the handles. Select any of the handles on either end, and click to place the dimension. Set the dimension in the Modify box.
What is spline command in Solidworks?
The SOLIDWORKS software supports two types of splines, B-splines and style splines. You can use B-splines to create complex curves. You can define and modify them using several controls, including spline points, spline handles, and control polygons. You define and control the curves using control vertices. …
Is 3665 a standard spline?
This standard has been prepared to rationalize the production and to facilitate interchangeability of exter- nal and internal splines. 0.4 This standard deals with involute sided splines of 30′ pressure angle for general engineeering ‘purposes.
What is difference between spline and serration?
Although a splined shaft looks like having a series of shaft keyways with keys pushed in, splines are considerably stronger than the keyed joint as the keyways weaken the shaft and reduce its torque carrying capacity.
Can you dimension a spline?
To dimension a spline, you must dimension its endpoints. You need not add spline dimensions if the spline is attached to other geometry and the endpoints are dimensioned. You can dimension spline endpoints using linear dimensions, tangency (angular) dimensions, and radius-of-curvature dimensions.
How do you define spline curve?
A spline curve is a mathematical representation for which it is easy to build an interface that will allow a user to design and control the shape of complex curves and surfaces. The general approach is that the user enters a sequence of points, and a curve is constructed whose shape closely follows this sequence.
What is a spline in math?
In mathematics, a spline is a special function defined piecewise by polynomials. … In the computer science subfields of computer-aided design and computer graphics, the term spline more frequently refers to a piecewise polynomial (parametric) curve.
What is the use of spline command?
The spline command in AutoCAD is used to create a smooth curve, which passes through a set of predefined points. It creates a non-uniform curve passing through the points. Thus, spline can be created by defining fit points or Control Vertices (CV) points.
How do you explode a spline?
If the spline and arc are joined as a single polyline object, type X or EXPLODE at the command line, select the object, and hit the Enter key. The spline and arc objects will now be separate objects.
How do you smooth a spline in Solidworks?
To access this tool you must be in an open sketch, and have the spline selected in the graphics area. Next, head to Tools > Spline Tools > Simplify Spline. In the dialog box you can either set a value for tolerance and click OK or click Smooth and watch SOLIDWORKS do its thing (always my preferred option).
What is din5480?
DIN 5480 was structured to permit easy slip-fitting of components such as, for instance, ball or roller bearings. This condition is met by making the reference diameter equal to the bore of the bearing and then modifying the profiles of the teeth of the hub and the shaft accordingly.
What is the base diameter of a spline?
Base Circle is the circle from which involute spline tooth profiles are constructed. Base Diameter (Db) is the diameter of the base circle. circular pitch. The basic space width for 37.5- and 45-degree pressure angle splines, how- ever, is greater than half the circular pitch.
How do you measure the thickness of spline teeth?
Effective Tooth Thickness of an external spline is equal to the circular space width on the pitch circle of an imaginary perfect internal spline, which would fit the external spline without looseness or interference, considering engagement of the entire axial length of the spline (i.e. the smallest space width that …
What is pressure angle in spline?
The pressure angle of a spline is the angle between where the pitch diameter meets the involute curve and a tangent point on the base diameter (fig. 4). There are three major pressure angles used in the spline rolling industry today. These angles are 30, 37.5 and 45 degrees.
