Gear rack 8 dp 20 pressure angle 1 1 2 in width 4 ft oal steel material mi item 00372213 manufacturer description. Pressure angle α pressure angle is the leaning angle of a gear tooth an element determining the tooth profile. For smooth quiet operation at high speeds under heavy loads helical gears have curved teeth that engage gradually and stay in contact longer than straight teeth. The 20 degree pressure angle pa provides a lower contact ratio between gears than a 14 5 degree pressure angle.

The current industry standard gears with a 20. Recently the pressure angle α is usually set to 20 however 14 5 gears were prevalent. One would therefore employ a helical gear cut with a standard spur gear 72 pitch hob set to cut a helix angle of 27 degrees 16 minutes.
