Tutorial - Modeling Crank Shaft in SolidWorks?

This is tutorial on making crank shaft. The main problem with making such design is with reading the dimensions on the drawing sheet. Well i have solved it for you. In this tutorial we will go through simple extrusion operation to make crank shaft.

1. Step 1:

Right Plane>>Sketch.

2. Step 2:

Draw a circle of 120mm and 4 holes of 12mm at 42.5mm from origin.

3. Step 3:

Extrude it by 16mm.

4. Step 4:

Right face>>Sketch.

5. Step 5:

Draw a circle of 50mm dia.

6. Step 6:

Extrude it by 40mm.

7. Step 7:

Right face>>Sketch.

8. Step 8:

Draw this profile.

9. Step 9:

Extrude it by 22mm.

10. Step 10:

Right face>>Sketch.

11. Step 11:

Draw a circle of45mm at 40mm from origin.

12. Step 12:

Extrude it by 35mm.

13. Step 13:

Right face>>Sketch.

14. Step 14:

Draw this profile.

15. Step 15:

Right face>>Sketch.

20. Step 20:

Draw this profile.

21. Step 21:

Extrude it by 22mm.

22. Step 22:

Right face>>Sketch.

23. Step 23:

Draw a circle of 45mm.

24. Step 24:

Extrude it by 45mm.

25. Step 25:

Right face>>Sketch.

26. Step 26:

Select this face and click Convert entities since the profile is same.

27. Step 27:

Extrude it by 22mm.

28. Step 28:

Right face>>Sketch.

29. Step 29:

Convert the circular edge.

30. Step 30:

Extrude it by 35mm.

31. Step 31:

Right face>>Sketch.

32. Step 32:

Convert this face since the profile is same.

33. Step 33:

Extrude it by 25mm.

34. Step 34:

Right face>>Sketch.

35. Step 35:

Convert the cirular edge from 4th extrusion.

36. Step 36:

Extrude it by 35mm.

37. Step 37:

Right face>>Sketch.

38. Step 38:

Select the 3rd extrusion face and convert entities.

39. Step 39:

Extrude it by 22mm.

40. Step 40:

Right face>>Sketch.

41. Step 41:

Draw a circle of 45mm dia.

Extrude it by 145mm.

43. Step 43:

Right face>>Sketch.

44. Step 44:

Draw a rectangle of this dimension with one point coincident on the circular edge at a distance of 4.5mm.

45. Step 45:

Extrude cut it by 100mm.

46. Step 46:

Right face>>Sketch.

47. Step 47:

Draw a circle of 28mm.

48. Step 48:

Extrude it by 28mm.

49. Step 49:

We have the crank shaft.
