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.

A planetary gear train is shown in the figure. The sun gear (gear 1) is fixed, it has a 1-in. pitch diameter with a diametral pitch of 12. Gear 3 has 36 teeth and gear 4 has 20 teeth. Gear 5 has 40 teeth and is keyed to the same shaft as gear 4. Gear 5 mates with the ring gear (gear 6), which serves as the output from the train and has 160 teeth. The carrier (link 2) serves as the input to the train, determine the rotational velocity of the ring gear when the input shaft rotates at 1125 rpm clockwise.
A spur gear set is cut with a hob. The spur gears have a pressure angle of 20 degrees and a diametral pitch of 16 teeth/inch. The pinion has 32 teeth while the gear has 80. The customer wants to replace the spur gear set with a custom helical gear set. The only requirements are: (1) the same hob must be used (2) the gear set center distance must remain the same (3) the gear ratio must remain the same. The designer has decided to use a helical pinion with 28 teeth. For the helical gear set, select the proper helix angle that will guarantee the three requirements. Report your answer in degrees, 3 decimal places.
Two spur gears are to have a ratio of 9:3 and a 7mm module. If the center distance is to be approximatively 200mm, calculate the following:o Circular pitch value;o Number of teeth on the wheel (gear);o Number of teeth of the pinion;o Pitch circle diameter of the gear;o Pitch circle diameter of the pinion;
