Two shafts x and y are in the same line (axis in one line). They are geared
Question:
Two shafts x and y are in the same line (axis in one line). They are geared together through an intermediate
parallel shaft carrying wheels B and C which mesh with the wheels on A and D respectively, as
shown in Fig.15.24. Wheels A and B have a module of 4 mm and the wheels C and D have a module
of 9 mm. The number of teeth on any wheel is not to be less than 15 and the speed of D is to be about,
but not greater than 1/12 the speed of A and the ratio of each reduction is the same. Find (a) suitable
number of teeth for the wheels, (b) the actual reduction, and (c) the distance of the intermediate shaft
from the axes of the shafts A and D (centre distance), (d) Indicate the configuration with a sketch, (e)
How is addendum modification related to correction of gears and when are they used in practice? Gear
A is on shaft A and gear D on shaft D)
