What is bushed pin type coupling?

A bushed-pin flexible coupling, as shown in Fig. is a modification of the rigid type of flange coupling. The coupling bolts are known as pins. The rubber or leather bushes are used over the pins. The main modification is to reduce the bearing pressure on the rubber or leather bushes and it should not exceed 0.5 N/mm2.

What is bushed coupling?

A Flexible Pin Bush Coupling is a type of Power Transmission Mechanical Coupling used to connect two shafts together at their ends for the purpose of transmitting power. This type of Pin Bush type flexible coupling has pins over which rubber or leather bushes are used. …

Which material is used for bushed pin type flange coupling?

Ans. (c) Rubber is used for bushes in the bushed pin type flexible coupling.

What type of coupling is a flange coupling?

Flange coupling is a sort of connector between turning chutes that have two arrangements of flanges. The flanges are tightened together by means of a number of nuts and bolts. One of these flanges or chutes is fixed at the end of each shaft.

What are the types of coupling?

Examples of material flexing couplings are jaw, sleeve, tire, disc, grid and diaphragm couplings.

• – Jaw Couplings.
• – Sleeve Coupling.
• – Tire Coupling.
• – Disc Coupling.
• – Diaphragm Coupling.
• – Gear Couplings.
• – Grid Couplings.
• – Roller Chain Coupling.

What is a flexible coupling?

The purpose of a flexible coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch.

What are the parts of flange coupling?

There are three different types of flange couplings.

• Unprotected type flange coupling (The bolts and nuts are totally exposed)
• Protected type flange coupling (The bolts and nuts are recessed in the flanges)
• Marine type flange coupling (Flanges are an integral part of the shaft)

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 to each other and communicating through data.

What is a Lovejoy coupling?

Supplied and in use around the world, Lovejoy’s curved jaw couplings can meet your every curved jaw need. The curved jaw three-piece design incorporates a radial curvature to the jaw face, as well as both radial and axial curvature (crowning) to the elastomer (spider).

Which type of coupling is flexible?

Example of some flexible coupling types: Gear Coupling. Disc Coupling or diaphragm Coupling (LAMAFLEX COUPLING) Chain Coupling. Grid Coupling.

Where is flexible coupling used?

Flexible couplings are usually used to transmit torque from one shaft to another when the two shafts are slightly misaligned. They can accommodate varying degrees of misalignment up to 1.5° and some parallel misalignment. They can also be used for vibration damping or noise reduction.

When to use a bushed pin flange coupling?

Bush pin type flange coupling is used to connect of shafts which having a small parallel misalignme nt, angular misalignment or axial misalig nment. This is a modific ation of the protected type flange coupling which has pins (covered by rubber or leather bushes) and it works with coupling bolts.

What are the different types of shaft couplings?

This is used for slightly parallel misalignment, angular misalignment, or axial misalignment of the two shafts. It is a modification of the rigid flange coupling. It consists of two halves that are dissimilar in construction and bolts known as pins, rubber bushes which are used over pins.

Why are eight milled bolts used in bushed pin coupling?

Eight milled bolts (four on each semi-coupling) allow the transmission of the torsion moment in both directions of rotation, in one direction becoming rigid and thus behaving like a safety coupling. Finite element method is used to obtain the mechanical response of this new type of coupling.

What kind of coupling is needed for centrifugal pump?

Q.1 It is required to design a bushed pin type. Flexible coupling to connect the output shaft of an electric motor to the shaft of a centrifugal pump. The motor delivers 20KN power at 720 rpm. The starting torque of the motor can be assumed to 150% of the rated torque.
