Determination of conditions of contact in zones of contact between two bodies by means of a sensor sensitive to heat radiation

摘要

To determine the conditions of contact between two bodies in contact, the heating caused by pressure and relative motion is recorded by means of a sensor sensitive to heat radiation. This method is suitable, inter alia, for determination of the contact pattern between gear pairs, particularly those in bevel gear and hypoid gear mechanisms. The method is employed on a running-test machine which also allows the recording of the transmission behaviour and of the circumferential backlash. It is thus possible to perform automated quality assessment and adjustment of bevel gear sets and hypoid gear sets.
