What is spacer type coupling?

In pump design, a spacer coupling is a cylindrical shaped piece introduced between the pump shaft coupling hub and motor shaft coupling hub. It gives enough space to remove the pump mechanical seal when doing maintenance, without moving either the pump body or the driver.

What are the three types of couplings?

They can create effective seals between two tubes, and hence, in addition to power transmission, they are used in pressurised fluid systems. Flange couplings are of three major types: Unprotected type flange coupling. Protected type flange coupling.

What are the types of couplings?

Couplings fall into two main categories: Material Flexing and Mechanical Flexing. The material flexible types obtain their flexibility from stretching or compressing a resilient material, such as rubber, or from the flexing of thin metallic discs or grid.

What is coupling and its type?

However there are two main types of couplings (Fig 1) which are (i) rigid couplings, and (ii) flexible couplings. Rigid couplings are used for shafts having no misalignment. Since these couplings cannot absorb any misalignment the shafts to be connected by a rigid coupling must have good lateral and angular alignment.

What is flange coupling?

noun. engineering a driving coupling between rotating shafts that consists of flanges (or half couplings) one of which is fixed at the end of each shaft, the two flanges being bolted together with a ring of bolts to complete the drive.

What is pump coupling?

Couplings also known as shaft couplings are used to connect the rotating pump shaft with the drive shaft of the motor ensuring torque is transferred to the pump with minimal losses.

What are the types of flexible coupling?

The Complete Library of Types of Flexible Coupling

  • Gear Couplings.
  • Grid Couplings.
  • Roller Chain Couplings.
  • Slider Block Couplings (Oldham’s)
  • Metallic Beam Couplings.
  • Bellows Couplings.
  • Universal Coupling.

What is the name of coupling?

A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other.

Which type of coupling is best?

A good software will have low coupling. Types of Coupling: Data Coupling: If the dependency between the modules is based on the fact that they communicate by passing only data, then the modules are said to be data coupled. In data coupling, the components are independent of each other and communicate through data.

What is flange and types?

Usually, flanges are threaded or welded, and you can connect two flanges by bolting them with gaskets and providing a seal that gives easy access to the piping system. These flanges are available in many types like socket weld flanges, blind flanges, weld neck flanges, and slip-on flanges, etc.

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.

What are the types of couplings used in pumps?

What is HRC coupling?

HRC couplings consist of 2 cast-iron halves attached to shafts by means of either hub mount (H Flange) or face mount (F Flange) taper bushes. Between these two halves is a rubber “spider” that serves as a shock absorber. HRC Couplings allow for a limited parallel misalignment (0.5mm) and axial misalignment (1.5mm).

What is flexible coupling and rigid coupling?

Rigid couplings provide a rigid connection; the two shafts are firmly connected, and the coupling allows for a smooth transmission of torque throughout the system. Flexible couplings create flexible connections, and the components can lose some of the torque power through the interaction.

What is flex coupling?

A flexible coupling exists to transmit power (torque) from one shaft to another; to compensate for minor amounts of misalignment; and, in certain cases, to provide protective functions such as vibration dampening or acting as a “fuse” in the case of torque overloads.

Why are couplings 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 are the seven types of coupling?

Types of Coupling

  • Common Coupling.
  • Content Coupling.
  • Data Coupling.
  • Control Coupling.
  • Stamp Coupling.
  • External.

Which is flexible type of coupling?

Gear Couplings A common type of mechanical flexible coupling is gear coupling. Each coupling consists of two hubs with crowned external gear teeth. The hubs mesh with two internally splined flanged sleeves that are bolted together. They are called gears as a result of the generally huge size of the teeth.

What’s the meaning of flanges?

Definition of flange (Entry 1 of 2) 1 : a rib or rim for strength, for guiding, or for attachment to another object a flange on a pipe a flange on a wheel. 2 : a projecting edge of cloth used for decoration on clothing a jacket with flange shoulders.

What is rigid coupling?

A rigid coupling is one that does not allow axial or radial motion between the driving and driven shafts. As shown in Fig. 3.130, a rigid coupling consists of two flanges, one mounted on each shaft. Rigid couplings require exact alignment between shafts otherwise considerable wear on the bearings and seals will occur.
