Two Standard spur gears have a diametral pitch of 10, a pressure angle of 20°, and a velocity ratio equal to 3.5 : 1. The center distance is 8.55 inch. Two helical gears are to be used to replace the two spur gears such that the center distance and angular velocity ratio remain unchanged. The helical gears are also to be cut with the same hob as that used to cut the spur gears. Determine the helix angle, tooth numbers, and minimum face width for the new gears if the helix angel is kept to a minimum.

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

Two Standard spur gears have a diametral pitch of 10, a pressure angle of 20°,
and a velocity ratio equal to 3.5 : 1. The center distance is 8.55 inch. Two helical
gears are to be used to replace the two spur gears such that the center distance
and angular velocity ratio remain unchanged. The helical gears are also to be cut
with the same hob as that used to cut the spur gears. Determine the helix angle,
tooth numbers, and minimum face width for the new gears if the helix angel is
kept to a minimum.

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.
