A pinion shaft consists of a pinion machined directly onto the drive shaft in a gear unit to form a single component. The pinion on the pinion shaft is the smaller gear (spur gear) in a gear unit and usually serves as a drive gear. The gears in a gear unit often take the form of a pinion shaft because of the transmission ratio at high torques and the small size of the pinion shaft. This makes it possible to extend the utilization limits and increase the resource efficiency of conventional processes using pinions. Thanks to the pinion shaft’s small space requirements and high performance capability, it is the solution of choice for transmitting torques in the automotive and aerospace industries as well as in general engineering. For manufacturing pinion shafts up to a length of approximately 420 mm, we use high-precision, premium CNC gear-cutting machines from Gleason-Pfauter and Köpfer. Various gearing types are possible, such as pinion shafts with splines according to DIN 5480 or running gears according to DIN 867. Additional gearings can be manufactured to meet specific requirements, both individually and position-specific, using the high-precision touch probe system of modern CNC gear-cutting machines. To meet extremely precise quality specifications, we perform the hard-fine machining of gearing on state-of-the-art gear flank grinding machines from Reishauer and Höfler. On the basis of this manufacturing technology, we are able to produce components with shape, position and surface roughness characteristics that meet quality specifications, and at the same time we guarantee that the prescribed surface quality and profile accuracies are fulfilled.
