What is a coupling on a pump?

What is a coupling on a pump?

Pump couplings connect the pump shaft and motor shaft together in order for the motor to efficiently transmit power to the pump. Like everything else on the pump, selecting the right coupling for the application can have positive or negative impact on the pump’s lifetime performance.

What are the different types of shaft couplings?

Diaphragm couplings are often used in high-power transmission applications such as turbomachinery. They usually use one or more flexible metal convoluted disks to transfer power to an inner spacer shaft and then back out to the powered machinery by another diaphragm stack.

How does a shaft coupler work?

A coupling is a mechanical element part that connects two shafts together to accurately transmit the power from the drive side to the driven side while absorbing the mounting error (misalignment), etc. of the two shafts.

What is shaft coupling?

A shaft coupling is a mechanical component that connects the drive shaft and driven shaft of a motor, etc., in order to transmit power. Shaft couplings introduce mechanical flexibility, providing tolerance for shaft misalignment. In NBK, the former is called a coupling and the latter is called a shaft coupling.

What are the requirements of good shaft coupling?

Requirements Of A Good Shaft Coupling

  • It should be easy to connect or disconnect.
  • It should transmit the full power from one shaft to other shaft without losses.
  • It should hold the shaft in perfect alignment.
  • It should reduce transmission of shock loads.
  • It should have no projecting parts.

What is a shaft coupling?

shaft coupling, in machinery, a device for providing a connection, readily broken and restored, between two adjacent rotating shafts.

How do I choose a shaft coupling?

How to select couplings

  1. Select the coupling type suitable to the intended usage.
  2. Select the material of the coupling in line with the environment of usage.
  3. Select the coupling size fitted to the torque, space and bore size required.
  4. Select the fastening method between the shafts and the coupling.

Where is coupling used?

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both.

What type of connection is coupling?

What type of connection is coupling? Explanation: Coupling is a linkage between two rotating shafts at the ends. It is a permanent connection, which transmits power.

What is shaft and its types?

Types of Shaft Shafts are mainly classified into two types: Transmission shafts are used to transmit power between the source and the machine absorbing power. e.g., countershafts, line shafts, and all factory shafts. Machine shafts are an integral part of the machine itself. Axle shafts are used in vehicles.
