    12L14 heat treat

    We currently carbon nitride our 12L14 pinions to provide a case hardening. We would like to get more strength from this material. Is there a way to induce carbon into the part during the heat treat to increase strength? We would like to match the strength of 4140 thru HT to Rc30. Thanks

    Buckingham wear equation

    We are experiencing pinion wear (channeling). I have analyzed the situation using the Buckingham equation for wear of gear teeth and we are nowhere near the conditions where we would experience wear. Does the Buckingham equation have speed limitations? The pinion is at 6200 RPM, hardness of...

    gear pressure angle

    We are suspect of the pressure angle we get from our gear suppliers. Documentation has been lost, etc. What is the best way to measure the pressure angle? We have an optical comparator but not a CMM. I have tried to measure the pressure angle on our comaparator but get values like 16 deg. when...
