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.

Question

Q2
A commercial enclosed gear drive is to be designed. Initially, the following is specified. The drive is to
transmit 9.6 kW with an input pinion speed of 350 rev/min. The drive is to consist of two spur gears,
with a 20° pressure angle, and the pinion is to have 20 teeth driving a 64-tooth gear. The pinion is
made to be Grade 1 nitraded though hardened steel at 254 Brinell. The gear is made to be Grade 3
carburized and hardened steel at 284 Brinell. Both gears made to No. 6 quality standards. The gears
will be uncrowned, centered on their shafts between bearings. A pinion life of 19232 cycles is
desired, with a 99.99 per cent reliability. Analysis gears stress (bending and pitting) according to the
AGMA approach and the corresponding factor of safety.

A pair of steel gears have a design life of a million cycles. They have 20° full-depth teeth with a diametral pitch of 8. Both gear and pinion are made of steel heat-treated to 350 Bhn, and both have a face width of 1.0 in. The teeth are machined with the highest quality hobbing operation. The pinion has 35 teeth and rotates 2000 rpm. The gear diameter over pinion diameter ratio is 2. The gears stay below a temperature of 140 °F. Assume a mounting correction factor of Km = 1.6 and an overload factor of Ko = 1. Use a reliability of 99.9% and a safety factor of 1.5. Use the pinion for the bending fatigue calculations and assume that there is no load sharing. A. What is the fatigue strength for these conditions. B. What is the tangential force acting on the gear teeth? C. Estimate the horsepower that can be transmitted, based only on bending fatigue.
