Here is my solution. In this the rope is just a part which don't work as in Assembly or we can say that for representation only.

1. Step 1:

   Start SolidWorks in Part mode.
   

   

2. Step 2:

   Right plane >> Sketch.
   

   

3. Step 3:

   Draw this sketch.
   

   

4. Step 4:

   Revolve it. Save this part.
   

   

5. Step 5:

   New part. Front plane >> Sketch.
   

   

6. Step 6:

   Draw a rectangle.
   

   

7. Step 7:

   Extrude it.
   

   

8. Step 8:

   Front face >> Sketch.
   

   

9. Step 9:

   Draw three circles.
   

   

10. Step 10:

    Extrude them.
    

    

11. Step 11:

    Save this part.
    

    

12. Step 12:

    Start a new assembly and insert this part.
    

    

13. Step 13:

    Insert three part1.
    

    

14. Step 14:

    Mate. Select this face of the pulley.
    

    

15. Step 15:

    And this face of the part.
    

    

16. Step 16:

    Generate coincident mate.
    

    

17. Step 17:

    Select inner face of the pulley.
    

    

18. Step 18:

    And the circular face.
    

    

19. Step 19:

    Generate mate.
    

    

20. Step 20:

    Generate similar mates for other parts.
    

    

21. Step 21:

    Assembly features >> Belt/Chain
    

    

22. Step 22:

    Select this face.
    

    

23. Step 23:

    And this face.
    

    

24. Step 24:

    And third face.
    

    

25. Step 25:

    Enable Create belt part and click OK.
    

    

26. Step 26:

    Click OK and save the assembly file.
    

    

27. Step 27:

    Now the belt part is generated.
    

    

28. Step 28:

    Open the belt part.
    

    

29. Step 29:

    Reference Geometry >> Plane.
    

    

30. Step 30:

    Select the line and the end point. Click OK.
    

    

31. Step 31:

    Plane1 >> Sketch.
    

    

32. Step 32:

    Draw two center lines.
    

    

33. Step 33:

    Draw 4 equal circles tangent to them in each quadrant.
    

    

34. Step 34:

    Trim the inner lines.
    

    

35. Step 35:

    Exit the sketch. Swept boss/base tool.
    

    

36. Step 36:

    Select the circle sketch as profile and the belt sketch as path.
    

    

37. Step 37:

    Under orientation select twist along path.
    

    

38. Step 38:

    Input no. of turns.
    

    

39. Step 39:

    Click OK.
    

    

40. Step 40:

    Window >> Assembly.
    

    

41. Step 41:

    And we have rope drive.
