Types of mechanical coupling pdf

Examples: FLEXIBLE COUPLING. Bushed pin type coupling Universal coupling Oldham coupling Bellows coupling low backlash. Spider or jaw coupling or ( lovejoy coupling ) elastomeric inserts for flexibility, vibration reduction. Thompson coupling Resilient coupling Disc coupling Diaphragm coupling Gear coupling.

Chapter 10: Mechanical joints – wide-tolerance couplings and flange adaptors 10. Wide-tolerance couplings Wide-tolerance couplings (Fig. 1 and Fig.

1) connect two plain pipe-ends by making a mechanical joint to each pipe.

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. A coupling can be rigid or flexible, allowing various amount of angular, radial, and axial misalignment between the two shafts. 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. Couplings can be used to reduce shock and overloa.

Based on the area of applications there are various types of coupling available. But they are generally categorised in the following varieties. Other coupling types include meshing tooth , or Hines , designs , pin and bush couplings , and spline couplings.

Clamp or split-muff coupling. In this coupling, the muff or sleeve is made into two halves parts of the cast iron and they are joined together by means of mild steel studs or bolts. What are the main types of coupling? What is the function of a mechanical coupling?

Free 2-day Shipping On Millions of Items. This feature is a great advantage in tunnel, bridge and mine applications. Shaft couplings are used in machinery for several purposes 1. To provide for connection of shaft of units those are manufactured separately.

Continuing Education and Development, Inc. In this the two misaligned shafts have disc shape flanges with rectangular slot at the middle. 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, sleeve members having internal gear teeth, and a floating spacer. An extensive range of couplings for mechanical power transmission. Many standard coupling types and sizes held in stock for quick despatch.
