Coupling types ppt

Sleeve or muff coupling A Sleeve coupling is a basic type of coupling. Muff or Sleeve coupling. Bush Pin type flexible coupling. Universal joint or Hooke’s joint.

A device that is used to connect two shafts together for the purpose of power transmission. It is the simplest type of rigid coupling , made of cast iron.

It consists of a hollow cylinder whose inner diameter is the same as that of the shaft (sleeve). It is fitted over the ends of the two shafts by means of a gib head key,. FLEXIBLE COUPLING Flexible couplings are designed to transmit torque while permitting some radial, axial, and angular misalignment.

Shanmukha Nagaraj, RVCE. Examples : FLEXIBLE COUPLING. There are a number of different types of mechanical, flexible couplings. The mechanical nature of this type of coupling allows for nearly unlimited horsepower and torque capabilities. A common type of mechanical flexible coupling is the gear coupling.

This coupling consists of two shaft hubs with external gear teeth cut integrally on the hubs.

This consists of a pipe whose bore is finished to the required tolerance based on the shaft size. Sometimes, a coupling is asked to absorb shock or vibration. Selecting the right coupling depends on four basic conditions of shaft misalignment or movement. It means a change in the second module will lead to the changes in the dependent module.

Other types of flexible couplings include limited end float, metal disk, diaphragm, and jaw- type. The three functions of flexible couplings are given below. They must transmit power. 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. Material flexing couplings do not require lubrication, with the exception of grid couplings.

Type S coupling The Type S coupling features high strength cast-iron flanges, that are bored to size for a clearance fit, and balanced to AGMA Class Standards, resulting in smooth operation for pumping applications. With one setscrew over the keyway and the other at 65°, D-Flex S flanges provide optimum shaft attachment. Other coupling types include meshing tooth, or Hines, designs, pin and bush couplings, and spline couplings. Coupling Applications and Industries. The standard coupling (type K) limits the torque to 1. Fitting so-called delay chambers allows reduction of the start-up torque.

The result is a smoother start-up with a longer start-up phase. The oil in the chamber reaches the working chamber only slowly. Various different types of stage coupling are defined depending on the components used for interconnecting the different stages of a multi-stage transistor.

The components most often used for coupling are cables, resistors, capacitors, and transformers.

The principal mechanism for J- coupling is through bond polarization, but there are situations where a through-space effect seems to be operative. Cohesion and coupling are also relevant at the level of logical tiers (resource:integration:logic:presentetion:view). Since universal joints are frequently use and thee r analysis is complex, a separate section is devoted to them following this section.
