What does spline do in Inventor?

2D and 3D splines are curves of constantly changing radius. Inventor supports two types of splines: interpolation splines and control vertex splines. Interpolation splines pass through a series of points, called fit points. You modify the curve using handles on the points.

How do you make an O ring in Inventor?

Design o-rings

On the ribbon, click Design tab Power Transmission panel O-Ring .
Select the cylindrical face.
Select the planar face or work plane to locate the groove.
Specify the distance from reference edge to groove.
In the O-Ring area, click the field to select an o-ring.
Click to select an o-ring.

How do you create an involute?

Draw a radial line from base circle on the right hand side to the pitch circle and another from the pitch circle to the new circle (the outside). Make these two lines equal length, so the outside circle is the same radial length larger than the pitch circle as the base circle is smaller.

Who invented the spline?

Isaac Jacob Schoenberg
B-spline curves and NURBS are most common which the term “B-spline” was coined by Isaac Jacob Schoenberg in 1946, and is short for basis spline. A spline function of order n is a piecewise polynomial function of degree n-1 in a variable x.

How do you make a groove in a shaft in Inventor?

On the Design tab, select Cylinder in the tree control. In the Section features drop-down menu, Add Groove – A, or Add Groove – B . Use the drop-down menu to specify how the groove position is measured within the shaft section. Enables groove dimensions editing.

What are the uses of involute splines?

Couplings with involute splines are suitable for transfers of great, cyclical, and shock torsional moments. This type is used both for fixed and for sliding couplings of cylindrical shafts with hubs. The use is similar as with parallel splines. Advantages of the coupling:

How do you calculate the involute function?

Let’s define an involute function. inv (α)=tan (α)−α=φ (All angles for the involute function must always be given in radians) With the involute function, many geometric spline parameters can be calculated. For example, the involute function can be used to determine the tooth thickness “s” on an arbitrary diameter “d” of a spline.

What is the fillet between involute profile and minor circle?

The fillet between the involute profile and the Minor circle depends on the tool used to machining the tooth. ( exceeds this tutorial). The fillet must be tangent to the involute profile and the minor circle Step 9: Extrude tooth. Extrude tooth at the desired thickness.
