As part of a transmission assembly project EST designed software for the parameterization and visualization of the adjusting and measuring process. This process is extremely elaborate. While turning the drive bevel gear (DBG) the collar nut which holds the gear in place, is tightened. Simultaneously the tightening torque and the friction torque of the DBG bearing is measured. Since in a certain area a joining process is also monitored in parallel to the nut tightening process the actual process data must be calculated by an algorithm designed by EST. The images show sections of the operator interface.
