A parallel shaft helical gear consists of a 20 dts drive pinion And a 96 driven gear. Both gears have a transverse diametrical pitch of 20 dts / in, a helix angle of 25 and a pressure angle on = 20 . The face width is 4 in., AND the gears are moving at 1600 ft / min, on the pitch line. The impeller is made of steel UNSG 10180 CD and without heat treatment; the driven one is made of grade 30 cast iron. Based on flexural strength calculations, evaluate the capacity or safe maximum power at hp. Consider general industrial service, and nG = 4.
The top half of a compound Epicyclic gearset is shown in Figure, with input shaft I rotating at a constant speed of 700 rpm in a clockwise direction and generating 12 kW input power. The Annulus wheel A2 isform a compound wheel with gear O and connected to an auxiliary gear N on shaft X. . The Annulus A1 rotates in a counter-clockwise direction at a speed of 5,300 rpm. Calculate the following using this condition: The speed and direction of output shaft O (NO), shaft X (NX) and gear ratio (n). If Annulus wheel A1 is locked calculate the speed and direction of output shaft O (NO), shaft X (NX) and gear ratio (n). The braking torque (Tb) (magnitude and direction) that must be applied to Annulus wheel A1 to hold it stationary, assuming gear transmission efficiency is 90%.

Q8/ An epicyclic reduction gear shown in figure, has a shaft A fixed to arm. The arm has a pin fixed to its outer end and two gears C and E which are rigidly fixed (C-E compound gear) revolve on this pin. Gear C meshes with annular gear D and gear E with pinion F. G is the driver gear and D is kept stationary. The number of the teeth is as follows: Tp = 80, Tc =10, TE = 24 and Tp = 10. The gear G runs at 200 rpm, find the speed of shaft A. (Area ge D

A pair of spur gears with module 5 mm and a center distance of 450 mm is used for a speed reduction of 5:1 calculate the number of teeth on pinion.
Please show your correct solutions to this Spur Gear problem neatly. Thanks. asap!
A similar pair of helical gears , also on parallel axes, are to have involute teeth, of 20o normal pressure angle, and 3 mm normal module. The wheels are to have 26 and 34 teeth, and to work with a centre distance of 146 mm. Calculate the transverse pressure angle in degrees.
