Classification and characteristics of flange shaft joints

Shaft joints play an important role in supporting the transmission of motion from one part to another. Besides, they also help prevent overloading, reduce dynamic loads, etc. Among the types of joints, there is a flange shaft joint, so what type of joint is this and what are its characteristics and uses? The article below will help you answer those questions.

Classification of Flange Shaft Coupling

Flange shaft coupling is designed to align the shaft and maintain alignment, the two flanges of the coupling are linked by bolts and nuts, this type of coupling is commonly used for heavy loads. Flange shaft couplings are divided into the following types:

Unprotected type: this is a type of flange shaft coupling with each shaft placed on each flange using an anti-fade lock, the flanges will be joined together with three or four bolts. The vibrating keys of the coupling are designed perpendicularly along the circumference of the shaft with the purpose of dividing the weakening effect caused by the keys.
Shielded type: Flange type shaft coupling consisting of bolts designed to protrude. The flanges will protect the coupling nuts, which can help workers avoid danger.
Marine type coupling: for this type of coupling, the flange is forged integrated with the shaft, the flanges of the coupling are still connected together by bolts without sharp heads, the number of bolts used depends on depending on the shaft diameter.

Although each type of flange shaft coupling has different advantages and disadvantages, they are basically manufactured to maintain transmission and reduce load on equipment during operation.

Characteristics of flange shaft coupling

Flange shaft coupling has the following characteristics:

  • Flexible to use, helps to connect two shafts by friction lock. Can be effectively and cost-effectively substituted for conventional presses. There is no need to use additional components for temperature regulation.
  • Assembly is easy and simple, not too difficult to do.
  • Has high concentricity and large axial tolerance, transmits moments accurately and without wear, and can withstand large bending forces.
  • Used in a number of equipment such as gearboxes, motors, belt drives used for mining, etc.
  • The flange used has many different types, from which the coupling also has a variety of connection forms that are convenient for disassembly, repair, maintenance, maintenance, replacement of details when needed, ... .
  • Able to adapt to all different conditions.
