subject: How To Create A Gear As Part Library By Zw3d [print this page] During the design process, we can put common standard parts into the custom parts library. By doing this, we can reduce the time of modelling, increase the reusability of standard parts, and improve work efficiency.
Designing idea In 3D parts models, we have a group of design parameters that control the shape and the topological relation model, as well as the design parameters of the part family size series. Also, we can choose different sizes to automatically generate a parts series of 3D models realized in the library.
1. Create the sample part
As shown below, we will make a standard involutes gear for the example.
1.1. The basic parameters of a gear:
Number of teeth = z
Module = m
Pressure angle =
Tip coefficient = Ha
Bottom clearance coefficient = Ca
Gear height = H
1.2. Because the number values for Teeth, Module, Pressure angle, and Tip coefficient have a standard value in each nation, we only need to control the Z and H in order to change the size and form of the gear.
1.3. Creating the gear model (Specific process is no longer in detail).
3.3. In the interface of the Part Library, we can see the pull-down menu in the Items of "Tool_Num" and "Height" have had the values to increased to the values below.
Now we have finish creating the gear part library.
