Thanks for the video! In the case of profile shifted helical gears, is the center distance equation the same except instead of using the normal pressure angle, we use the transverse pressure angle instead?
Sorry for the late reply, I have been on holiday.The formulas are basically the same, but not exactly. You can find more information at the following link: sdp-si.com/resources/elements-of-metric-gear-technology/page4.php
15:04: "The sum of the profile shift coefficients should not be significantly greater than one. This means that the sum of the profile shift coefficients should not exceed the value of the module."
