Question

A helical cast steel gear with 30^o helix angle has to transmit 35 kW at 2000 rpm. If the gears has 25 teeth, find the necessary module, pitch diameters and face width for 20^o full depth involute teeth. The static stress for cast steel may be taken as 100 MPa. The face width may be taken as 3 times to normal pitch. The tooth form factor is given by the expression y'= 0.154-0.912/T_E, where T_E represents the equivalent number of teeth. the velocity factor is given by C_v=6/(6+v), where v is the peripheral speed of the gear in m/s.

A helical cast steel gear with 30° helix angle has to transmit 35
kW at 2000 r.p.m. If the gear has 25 teeth, find the necessary
module, pitch diameters and face width for 20° full depth
involute teeth. The static stress for cast steel may be taken as
100 MPa. The face width may be taken as 3 times the normal
pitch. The tooth form factor is given by the expression
y'=D0.154–0.912/Tg, where T represents the equivalent num-
ber of teeth. The velocity factor is given by C,
6.
where
6 + v
v is the peripheral speed of the gear in m/s.
