6. INSERTION DIRECTION THE ASSEMBLY DIRECTION WILL BE THE BETA AXES.

7. ASSEMBLY SEQUENCE 1. Cover 2. Gasket 3. Adhesive time 4. Casing 5. Reorientation 6. Washers 7. Screws 8.Reorientation 9. Nameplate 10. Riveting 11. Reorientation 12. Leaf spring 13. Reorientation 14. Spring 15. Gear D 16. Gear C 17. Gear A 18. Time to add grease 19. Gasket 20. Adhesive time 21. Subassembly 22. Washers 23. Screws 24. Earth Lead

8. ASSEMBLY SEQUENCE 1. Gear B 2. Cover 3. Lever 4. Small washer 5. Lever Screw SUBASSEMBLY SEQUENCE

9. CALCULATIONS

10. CALCULATIONS

11. CALCULATIONS N → The theoretical minimum number of parts t a → Basic assembly time for one “ideal” part t ma → Estimated time to complete assembly of actual product.

12. CALCULATIONS To determine it, the three questions have been used: THEORETICAL MINIMUM NUMBER OF PARTS (N)

13. CALCULATIONS To determine it: ASSEMBLY EFFICIENCY

14. 2. REDESIGN OF THE GEAR BOX ASSEMBLY

15. NEW CASING JOINING THE BOTTOM COVER WITH THE GASKET AND THE PREVIOUS CASING. NOW THE CASING ONLY HAS TWO PINS FOR THE SCREWS.

16. NAMEPLATE JOINING THE NAMEPLATE TO THE NEW CASING. THE NAMEPLATE IS A RELIEF ON THE NEW CASING.

17. SPRING SLOT THE SLOT MAKES IT EASIER TO PLACE AND INSERT THE SPRING.

18. GEAR C/A JOINING THE GEARS C AND A INTO A SINGLE PART.

19. NEW GASKET AND COVER ONLY HAVE TWO HOLES TO PUT THE SCREWS.

20. FINAL ASSEMBLY NORMAL VIEW. EXPLODED VIEW.

21. FINAL ASSEMBLY MORE PICTURES.
