IMPROVEMENT IN DESIGN

As we have analysed, it is quite an efficient system within itself.Possible improvements in design are based on increasing the gear ratio. The possible improvements are:

  1. Either the no. of teeths on gear 1(b) should be decreased or the no. of teeths on gear5 should be increased in order to increase the gear ratio in backward motion.
  2. In the gears having two radii the ratio of teeths on (a) vs (b) should be increased as it will improve the gear ratio in forward motion.
  3. By insertion of another gear between gear3 and gear4 having two different radii with (a) in contact with (b) will improve the gear ratio in forward gear train by no. of teeths on (a) divided by the no. of teeths on (b).In this case the position of gears will change.
