Applications : Pinion Shaft
Pinion shafts are the input devices of a transfer case. They typically deliver power from the driveshaft to a single or pair of bevel ring gears that drive the axle(s) of a vehicle. They consist of a short, stout shaft that is terminated in a spline on the input end and a large spiral gear on the output end. Small and large bearings support the two respective ends of the part. Heat treating distorts the shaft. Straightening is needed prior to finish grinding of the bearing surfaces. Due to the short, stout configuration of the shaft, straightening is done at the small bearing with the large bearing then inspected to assure proper tolerance.
Our straightening technologies provide both manual and fully automated solutions for straightening these parts. Additionally, our flowforming technologies can be used to produce spline shaft blanks from tubular product.
