Custom Drive Shafts


The best drive shaft is usually constructed with steel, though some Custom Drive Shafts are made from composite materials such as aluminium shafting with the weld yokes welded at both ends.

What is a drive shaft?

  • Flange Yoke

  • Dust cap
  • Slip joint
  • Field yoke
  • Sliding yoke
  • Cork gasket
  • Universal joint assembly

How do drive shafts work?

zerk located on the U-joint that allows grease to be supplied the u-joint cap. The importance of the grease is to ensure low friction in-between the u-joint structure and the cap. A slip yoke connects the drive shaft to the transmission.

Movement between suspension and a surface is ensured by the slip yoke as well as the u-joints inside the Custom Drive Shafts. As the rear suspension moves, the drive shaft must simply get longer or shorter, while the slip yoke will slide back and forth as the output of the drive shaft changes the distance between the transmission and the differential.

How are drive shafts balanced?

When the height of suspension in a vehicle is modified, the driveshaft of the vehicle will become too short or too long as a result of the change in the distance between the rear differential and transmission. This may create an imbalance, and the drive shaft can fall off easily. Hence the drive shaft must be lengthened to make up for the distance between the transmission and differential. Lengthening Custom Drive Shafts is one of the best possible ways of creating more balance in automobiles and other applications involving the use of drive shafts.

What are the applications of a drive shaft?

Custom drive shafts are applicable in many ways; the most prominent one is the design of extra-fast cars used in drag-racing or competitive sports such as Formula one. Custom Drive Shafts are also used in the design of industrial production machines as well as computerized robots used in performing certain military activities. Drive shafts are very critical to creating a balance between moving metal objects hence they can also be used for heavy agricultural devices.

What causes drive shaft vibrations?

The drive shaft that is newly developed from the factor is usually out of round, and it is usually balanced but not straightened. This problem will create so much weight on the shaft, and cause it to vibrate.

How can BTI develop Custom Drive Shafts?

BTI can develop Custom Drive Shafts by replacing some of the parts of the drive shafts. The u-joints, for instance, are the first components of drive shafts that go bad, and this is caused by the needles becoming dry and worn out- this problem will eventually cause damages to the cap of the u-joint, which in turn wreak havoc on the weld yoke. Once the u-joints have destroyed the weld yoke, then a new yoke must be supplied and welded in the tube.

BTI develop Custom Drive Shafts by straightening the shafts before balancing them. Taking this step will keep the drive shafts within a 10- 1000th tolerance, to ensure that the drive shaft does not vibrate again.

Straightening of the drive shaft is an important step because, as the drive shaft is running at around 3500 rpm( and not straightened), there will be a “jump rope” effect. Once the straightening is performed by BTI, the balancing procedures can be performed. Balancing I a critical step because not all the parts in the drive shafts are machined correctly. The uneven metal problem on the drive shaft will be compensated for by the extra weight created during balancing; this means the weight will simply make the drive shaft equal all through its length.
