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.

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

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.
