Applications : Driveshaft
Driveshafts (or propshafts) deliver power from the engine transmission to the transfer case of a vehicle or the stern/prop drive of a watercraft. They consist of a long tube terminated in a variety of configurations (flanges, slip yokes, splines, etc.) for coupling of the input and output devices. The assembly of the terminations with the tube (generally done via welding) induces significant levels of heat that distort the tube. Straightening of the tube referenced to the mounting surfaces of the end terminations is then required. Straightening is generally done in three to five positions depending on the length of the tube. Precise straightening of the finished assembly simplifies final balancing.
Our straightening technologies provide both manual and fully automated solutions for straightening these parts. These spinforming technologies can be used to reduce driveshaft tube diameters where necessary. Advanced tooling developed by Hess Engineering facilitates precise, repeatable straightening results.
