Assembly of IC Engine Connecting rod

  1. 1. Hareesha N G, Dept of AE, DSCE 2
  2. 2. Hareesha N G, Dept of AE, DSCE 3
  3. 3. • Select XZ plane and create the sketch as shown • Use symmetric protrude, depth 33mm 4Hareesha N G, Dept of AE, DSCE
  4. 4. • Select front surface as shown and create the sketch as shown • Use cut out, depth 6.5 mm 5Hareesha N G, Dept of AE, DSCE
  5. 5. • Use smart mirror option and select previously created feature, and select mid plane as shown 6Hareesha N G, Dept of AE, DSCE
  6. 6. • Create a parallel plane at distance of 84 from right side surface of the main body and create sketch as shown in fig 1. • On right side surface of the main body as shown, create the sketch as shown in fig 2. fig 2 fig 1 7Hareesha N G, Dept of AE, DSCE
  7. 7. • Use lofted protrusion to create the feature as shown below. 8Hareesha N G, Dept of AE, DSCE
  8. 8. • Select YZ plane and create the sketch as shown • Use Hole option to create the hole as shown below. 9Hareesha N G, Dept of AE, DSCE
  9. 9. • Use smart mirror option to create the feature as shown below and select the mid plane, select both previously created features 10Hareesha N G, Dept of AE, DSCE
  10. 10. • Create angled plane as shown below. Giving 60O angle wrt horizontal plane, taking vertical plane as intersection. • Create a parallel plane as shown at distance 42mm from the previously created angled plane. • Create hole on parallel plane as shown below. • Take front plane create 30 deg line as shown. 11Hareesha N G, Dept of AE, DSCE
  11. 11. • On this 30 deg angled plane create hole as shown below. Also create cutout as shown for depth of 7mm 12Hareesha N G, Dept of AE, DSCE
  12. 12. • Mirror the previously created both features as shown below. Selecting smart mirror option and mid plane. • Create 3 circles of 24, 26, 24 mm respectively on parallel planes as shown in fig below. • Use lofted protrusion to create the feature shown, selecting those three circles. 13Hareesha N G, Dept of AE, DSCE
  13. 13. • create cut out as shown. • create protrusion as shown, selecting previously created sketch and using up to next option • Create oil hole using below sketch and using revolved cut out command 14Hareesha N G, Dept of AE, DSCE
  14. 14. Part-2 : Bush • Select XY plane, create the sketch as shown in fig, create feature as shown giving depth of 25mm, symmetric. • Create the sketch, on parallel plane which is at a distance of 9mm from center of cylinder, as shown in fig 2 and create cutout, give 0.5 depth • Create cutout with 2mm dia circle, use upto next. 15Hareesha N G, Dept of AE, DSCE
  15. 15. 16Hareesha N G, Dept of AE, DSCE
  16. 16. 17Hareesha N G, Dept of AE, DSCE 100o degree revolved cutout 45o to front plane 90o to 450 plane 2mm hole on 90o plane
  17. 17. 18Hareesha N G, Dept of AE, DSCE 0.5 mm cutout Sketch on the new plane Sketch on the 90o plane which was created earlier 0.5 mm cutout
  18. 18. 19Hareesha N G, Dept of AE, DSCE Mirror other side 1.5 mm cutout from bottom
  19. 19. 20Hareesha N G, Dept of AE, DSCE Sketch on plane normal to curve Swept Protrusion Sketch parallel plane
  20. 20. 21Hareesha N G, Dept of AE, DSCE Protrusion upto next Cutout through all
  21. 21. 22Hareesha N G, Dept of AE, DSCE Sketch 0n 3mm parallel plane from bottom, cutout 16 mm 2 mm cutout 1 mm round Through all, cutout
  22. 22. 23Hareesha N G, Dept of AE, DSCE Mirror other side Round 10mm both side Mirror all features other side 1.5 mm cutout , from bottom Sketch on plane normal to curve Protrusion upto next, taper 5o
