[Ya...] Posted February 26, 2020 Share Posted February 26, 2020 Hi, I have a silly question, what is V circle means for the Pitch measurement? By default, the Pitch measurement will be performed on the intersection of V circle / center face, and then Gear Pro will transform this measurement result onto the real pitch diameter to report the Fr, right? Since V circle is the default setting, it must be very important, but I can not find the definition of V circle anywhere. Could anybody give me a hint please? Thank you very much.111.png Link to comment https://qualityforum.zeiss.com/topic/15622-what-does-v_circle-means/ Share on other sites More sharing options...
[Ch...] Posted February 26, 2020 Share Posted February 26, 2020 Pitch circle. As far as the "V", I've always wondered as well. No Clue. Link to comment https://qualityforum.zeiss.com/topic/15622-what-does-v_circle-means/#findComment-84886 Share on other sites More sharing options...
[Ma...] Posted March 3, 2020 Share Posted March 3, 2020 The "V" circle is the diameter where the tooth thickness and space width should be equal. If the "ideal" measuring ball or wire size is calculated by standard methods, the "V" circle equates to the diameter at which they would be in two-flank contact with the part.

[Ch...] Posted March 3, 2020 Share Posted March 3, 2020 Thank you Mark. Does the V stand for a word (German) or is just the letter "V"? Link to comment https://qualityforum.zeiss.com/topic/15622-what-does-v_circle-means/#findComment-84890 Share on other sites More sharing options...
[Ma...] Posted March 4, 2020 Share Posted March 4, 2020 Please sign in to view this quote. You're welcome Christopher. I don't know the origin of the "V" symbol for this, but odds are very good that it relates to a German word.

[Wo...] Posted June 3, 2020 Share Posted June 3, 2020 V-Circle is deriving from x-Value. Calculated with dv = d +/- 2 * x * m ( +/- Outer or Inner gear) x is needed to shift ( verschieben in German, maybe this is V ) the Tip- and Root diameter to fit the gear in a gearbox, if the other gear is not fitting in the flanks. The distance of the axes can only fit to one pair of gears with x = 0.
