A.
For constant velocity ratio transmission between two gears, the common normal at the point of contact must always pass through a fixed point on the line joining the centres of rotation of gears.
|
|
B.
For involute gears, the pressure angle changes with the change in centre distance between gears.
|
|
C.
The epicyclic gear trains involve rotation of atleast one gear axis about some other gear axis.
|
