To quickly set the type of pulley, its operating and the other parameters, a simple and intuitive dialogue-box is opened with the appropriate commands described hereinafter.
As for all standard libraries, it is possible to create a part and insert automatically in the material’s slip the parts used. The code of the pulley’s part is customizable by editing the value in the appropriate space. If the box is left empty, the code will be created automatically.
Click on Codified Menu and a dialogue box appears and allows the user to select a specific pulley between all those codified.
- What
- Displays a dialogue-box to set the type and the specific parameters of a pulley to insert in the drawing.
- Why
- For the correct drawing of pulleys, with standard dimensions, by selecting in the appropriate list the type, the operating, and the desired line with the essential characteristics.
- How
- The dialogue-box opened with the command Top_Pulegge is divided in four main sectors, as described in the image below.
On the top left is displayed the preview of the object selected with the dedicated commands. Click on the image to change the pulley’s view.
In the same section, under the image, three pop-up lists are displayed to select the pulley, or its category, the type, or the type of category, and the operating which identifies the pulley’s type of shape.
In the first partition is also displayed the part destined to insert the codes of the pulley and, if necessary, of the belt. The belt codes are associated to the codes listed in the appropriate belt dialogue-box.
In the central section is displayed the button Codified menu, as previously described, and the part destined to modify the central hole of the pulley. The pulleys dimensions must be entered with the keyboard or selecting two points on the screen, but they should be between “Dm” and “d”.
In the same section, is possible to select how to draw the hole and, usually, select the pulley’s drawing mode. For these two characteristics, see page on pinions. The toggle Make Part inserts the selected component as a part.
On the right section, select in the drawing the pulley’s layering point. Under this image is possible to select the pulley’s view, which can be: Sectional, Front or Rear.
In this part are displayed the dialogue-box to select the materials necessary to create the part, and the dialogue-box to select the appropriate belt to draw a pulley sectioned and the belt.
Select in the appropriate list under those three sections, the parameters necessary to draw the pulley. Once confirmed the object to place in the drawing, just insert the object’s layering point and insertion angle.
