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.

Question

Q1
Design a 4:1 spur-gear reduction for a 59 kW, three-phase squirrel-cage induction motor running at
1244 rev/min. The load is smooth, providing a reliability of 99.9 % at 109 revolutions of the pinion.
Gearing space is meager. Use pinion materials to be Nitralloy 135M, grade 2 steel and nitrided
through-hardened grade 1 steel material to keep the gear size small. The gears are heat-treated first
then nitrided. Consider temperature factor is 1.1 for 250 0C.

p sa 15. A straight bevel gear pair has the following data: 50; P¿ 10; and 20° pressure angle. If the gear pair is transmitting 3.5 hp, compute the fore- es on both the pinion and the gear. The pinion speed is 1250 rpm. The face width is 0.70 in. Compute the bend- ing stress and the contact stress for the teeth, and specify a suitable material and heat treatment. The gears are driven by a gasoline engine, and the load is a conveyor provid- ing moderate shock. Assume that neither gear is straddle nounted. N₂ No = 25; No J (M
14-23 A spur gearset has 17 teeth on the pinion and 51 teeth on the gear. The pressure angle is 20° and the overload factor K, = 1. The diametral pitch is 6 teeth/in and the face width is 2 in. The pinion speed is 1120 rev/min and its cycle life is to be 10" revolu- tions at a reliability R = 0.99. The quality number is 5. The material is a through- hardened steel, grade 1, with Brinell hardnesses of 232 core and case of both gears. For a design factor of 2, rate the gearset for these conditions using the AGMA method.
