- 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.
