Different Methods Used to Fabricate Drive Shafts

When we talk of "drive shafts", we refer to the main component of an electrical generator that is fitted into a turbine that runs on electricity.drive shaft forging The drive shaft has the larger diameter than the shaft that connects the windings to the turbine hub. This makes it the main factor that determines the high voltage induced currents that are produced during a wind generator operation. There are several different types of manufacturing techniques used for the purpose of forging the drive shafts:

Long rod: This is the most common type of drive shaft forging procedure.drive shaft forging drive shaft forging The basic concept is that the large center section of a long rod is first pressed and driven into the small ring on the inside of the shaft. The rings and centers are made from steel so that the outside of the center section can be filed down to create a small flange on the inside of the shaft. After the forging is done, the other half of the shaft can now be processed by high speed heat treating, shot peening, rough metal casting, induction heating, gas tungsten forging and finalizing. The entire procedure is known as "punching out" the assembly of the rod/ shaft assembly into the housing.

Hot forging: This procedure uses a low temperature forge process that can forge alloys with extreme temperatures.drive shaft forging The use of a hot-forging procedure allows more control over the shapes that are produced during the process. With the use of a high temperature and a large forge area, it is very possible to shape the inner and outer rings, centers and flanges to almost any shape that an automotive manufacturer might desire. This process is currently used in the aerospace and automotive industry to manufacture a wide range of shaft assemblies. process. During the compression molding process, the manufacturers will place a number of layers near the head of the shaft or the blank from which the shaft is to be formed. These layers are known as the compression layers and these are formed using either a hot or cold method. When the compression is performed in a series of successive cycles or in a repetitive manner, the desired thickness, length and diameter of the shaft can be achieved.

Axle shaft and bearing forge: In order to manufacture a bearing or an axle shaft, a series of alternating magnetic fields are used to create a mandrel and a number of parallel rotating pieces on the mandrel. A heavy electric current is passed through the pieces in a circuit in order to induce rotation into the piece. A piece of steel fabric is then fed into the circuit and the piece is spun around the mandrel at a very high speed. This spinning action creates a tension on the fabric belt that is used to drive the bearing through the rollers. A similar type of method is also used in order to manufacture a number of drive shafts with a constant velocity application.

Half shaft forging: In order to make a housing for a rotating die or to install a bearing into the housing, a series of mandrels are forced into the material, which is kept spinning by a magnetic force. The entire procedure is referred to as half shaft forging. A similar type of process is also used in order to manufacture a housing that contains a rotating die. When a half shaft is used in the fabrication of a housing, the procedure is known as flat cutting. Another type of method that is sometimes used in order to fabricate a housing containing a rotating die is the use of the flat and half-ellipse die.
