The Klingelnberg PSKE 900 bevel gear prout machine is designed for the universal single-flank design of cone and crown rims. Here, gears can be measured and graphically evaluated by means of single-flank and two-flank welding. These test methods are particularly suitable for determining errors in the gear geometry such as concentricity and axial runout properties, deviations or pitch errors. Here, a practical installation situation of a gearing outside the gearbox is simulated under real load conditions and then evaluated. Deviations in the gear geometry, machining errors due to defective tools and damage to the gears can thus be detected and eliminated before assembly.
