Initiative: Kees Kloosterboer (SolidWorks Benelux) Educational Advisor: Jack van den Broek (Vakcollege Dr. Knippenberg) Realization: Arnoud Breedveld (PAZ Computerworks) Bearing Puller In this tutorial, we will build a bearing puller. This product consists of three parts. We will learn a few new functions in this tutorial. We will also perform a simple analysis on some of the parts. Work plan The first part we will make is the main bridge. We will make this according to the drawing below. Make a plan! How would you build this part? Make a plan for yourself and compare it with the plan we have developed for this tutorial. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 3 1 Start SolidWorks and open a new part. 2 Select the Front Plane and make a sketch like in the illustration on the right. The sketch consists of four lines and three dimensions. Make sure the left bottom corner of the sketch is at the origin. 3 1. Click on Arc in the CommandManager. 2. Click on Tangent Arc in the PropertyManager. 3. Click on the right end of the upper horizontal line. 4. Put the end of the arc at about the same loca- tion as in the drawing. The exact spot is not relevant at this point. 5. Push the <Esc> key to end the line command. 4 Set dimensions for the arc you have just drawn: 1. Click on ‘Smart Dimen- sion’ in the Command- Manager. 2. Click on the arc. 3. Set the dimension. 4. Change the radius of the arc to ‘85’. 5. Click on OK. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 4 5 Make a curved edge be- tween the arc and the ver- tical line. 1. Click on Sketch Fillet in the CommandManager. 2. Change the radius to ‘5mm’ in the Property- Manager. 3. Click on the arc, to the left of the vertical line. 4. Click on the vertical line, just below the arc. 5. Click on OK. 6 Click on ‘Features’ in the CommandManager and next on ‘Revolved Boss/Base’. 7 Next, you have to set the rotation axis: 1. Click on the left vertical line in the sketch. 2. Make sure the rotation angle in the Property- Manager is set to ‘360 degrees’ (a complete circle). 3. Click on OK. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 5 8 The basic form is ready. We will now remove three triangles from this body. Select the Top Plane and create a sketch like in the illustration on the right. The sketch consists of two lines emanating from the origin: one line goes straight up and the other runs downwards under an angle of about 120 degrees to the first line. Both lines cross the outside edge of the part. Set the dimension of ‘120 degrees’ between the two lines. 9 Make a parallel copy of the two lines. 1. Click on ‘Offset Entities’ in the CommandMa- nager. 2. Change the distance in the PropertyManager to ‘12.5mm’. 3. Make sure the option ‘Select chain’ is se- lected. 4. Click on one of two lines in the sketch. You can now see a pre- view. Both lines from the sketch are copied. 5. When the lines are co- pied in the wrong di- rection, click on ‘Re- verse’ in the Property- Manager. 6. Click on OK. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 6 10 Round of the corners be- tween the two lines. 1. Click on Sketch Fillet in the CommandManager. 2. Check to make sure that the radius is still 5mm (you set this in step 6 already, and it should have remained in SolidWorks). 3. Click on the corners of both copied lines 4. Click on OK. 11 Next, we will make con- struction lines from the first two lines we have drawn. 1. Select the first line. 2. Hold the <Ctrl> key on your keyboard and se- lect the second line. 3. Check the option ‘For construction’ in the PropertyManager. The two lines will now be displayed as centerlines. Tip! We have also used centerlines in other tutorials. These lines are actually auxiliary lines. When you use a sketch to make an extrusion, for example, SolidWorks only uses the ‘real’ lines and not the auxiliary lines. In step 13 you have seen that you can easily change a ‘real line’ (or circle of arc) into an auxiliary line and vice versa. For this the option, the ‘For con- struction’ box in the PropertyManager must be checked. 12 Next, we will cut a corner from the model: 1. Click on ‘Features’ in the CommandManager. 2. Click on ‘Extruded Cut’. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 7 13 You can see a small arrow In the model that indicates from which side of the sketch the material will be removed. 1. Make sure these arrows point outwards. Click on it when you need to change the direction. 2. Click on OK. Tip! In most cases you will use a closed sketch for an ‘Extruded Cut’. In the case of a circle or a square you will only make a hole in the shape of that sketch. In the last step, we used an open sketch to make an ‘Extruded Cut’. It is handled in the same way except for two differences: 1. An ‘Extruded Cut’ with an open sketch will always go through the entire depth of the model (‘Through all’). You cannot set a depth. 2. SolidWorks needs to know from which side the material has to be cut away. You must pay attention to the little arrow, which indicates the cutting side. By the way, you can also change this direction in a closed sketch and cut away the material from the inside or outside of the sketch boundaries. 14 For the next features we need an auxiliary line that runs through the middle of the model. This axis con- sists in the model already but is not visible with the standard (default) settings. 1. Click on the Hide/Show Items icon. 2. Make sure the button View Temporary Axes is set. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 8 15 Next, we can copy the part with the cut three times around the axis. 1. Select the last feature: ‘Extrude1’ in the Featu- reManager. 2. Click on the arrow be- low ‘Linear Pattern’ in the CommandManager. 3. Click on ‘Circular Pat- tern’. 16 1. Select the centerline that runs through the middle of the model. 2. Change the number of copies in the Property- Manager to ‘3’. 3. Click on OK. Tip! Notice that in the three last steps we first selected a feature in the Featu- reManager and then selected the ‘Circular Pattern’ command. At this point, SolidWorks ‘understands’ that you want to use this command for the se- lected items and automatically adjusts the settings in the PropertyManager. You can also do this in the reverse order by giving the command first and then selecting the elements in the PropertyManager. SolidWorks does not have a preference for how you do it. You will have to find out for yourself the approach that works best for you. SolidWorks voor lager and middelbaar technisch onderwijs Tutorial 8: Bearing Puller 9 17 We will now make a sketch on the lower surface of the model. Rotate the model so you can see the bottom plane of the part. 1. Click on the surface to select it. 2. Click on Normal To in the menu that appears. 18 Draw a Centerline. 1. Put the first point right on the origin. 2. Set a second point at a random distance direct- ly below the origin. 19 Draw a circle and a line at the locations indicated on the right. The midpoint of the circle must be on top of the cen- terline.
