Recognizing the demand that still exists in the USA for diametral pitch spur gears, KHK USA is now offering made to order 4DP, 6DP, 8DP, and 10DP spur gears in both 20 degree pressure angle and 14.5 degree pressure angle varieties.Please contact us today with you requirements for Diametral Pitch Spur Gears.
Helical Gear Pitch Diameter How To Measure TheThe problem is that I dont really know how to measure the Pressure angle or the Pitch Diameter.Ive been told that helical gears are very similar to spur gears but I dont what to be making any assumptions.Ive got a set of involute gauges (like a pitch gauge style) but Im not sure how to use those. ![]() If you are actually setting out to measure that gear (with a view towards making a mate from scratch), you have a very long haul in learning and doing ahead of you. Twice the distance from the center of rotation to the center of the contact patch. There is the small problem that you cant use wires; you need to use a ball contact. Pressure angle is the face angle measured perpendicular to the center but multiplied by the cosine of the helix angle. These should get you close enough you could pick out a gear from a list of gears. For recreating the gear or, for more precise measurements, you have other concerns. I dont possess VW gearbox clue but without further information I would not assume the teeth on you gear are involute form. For low noise, high pressure, gear boxes there are other forms that are used. You really cant even talk single numbers for Pressure Angle and Pitch Diameter as both change over the length of the contact patch.
