Calculate the power that can be transmitted safely by a pair of spur gears with the data given below. Calculate also the bending stresses induced in the two wheels when the pair transmits this power. Number of teeth in the pinion = 20 Number of teeth in the gear = 80 = 4 mm = 60 mm = 20° involute Module Width of teeth Tooth profile Allowable bending strength of the material = 200 MPa, for pinion = 160 MPa, for gear = 400 r.p.m. = 0.8 Speed of the pinion Service factor 0.912 = 0.154 т Lewis form factor %3D 3 Velocity factor 3 + v

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
