Concept explainers

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.

What is the radial load exerted by the pinion on the gear? Report your answer in lbf.
A gearset has a module of 5 mm, a 20 degree pressure angle, and a 24-tooth cast iron spur pinion driving a 48-tooth cast-iron gear. The pinion is to rotate at 500 rev/min. The objective is to calculate the power in kwatt that can be transmitted by the gearset.. In this case, the cast iron, cast profile gears and the velocity factor must be calculated from the Barth equation. The bending stress is limited to 50 MPa and the facewidth is 60 mm. The velocity factor is considered to be significant and must be used in stress calculations. Calculate the power in kwatt the gearset can transmit using the Lewis bending equation. Note: in this case the stress MUST be modified by the velocity factor, Kv.
