Question

A pinion having 20 involute teeth of module pitch 6 mm rotates at 200 r.p.m. and transmits 1.5 kW to a gear wheel having 50 teeth. The addendum on both the wheels is 1/4 of the circular pitch. The angle of obliquity is 20 degree. Find (a) the length of the path of approach; (b) the length of the arc of approach; ​

Answer 2

A pinion having 20 involute teeth of module pitch 6 mm rotates at 200 rpm and

transmits 1.5 kW to a gear wheel having 50 teeth. The addendum on both the wheel

is % of the circular pitch. The angle of obliquity is 20°. Find (a) the length of the path

of approach; (b) the length of the art of approached the normal force between the

teeth at an Instant where there is only at of teeth in contact
