Coupling types pdf

Examples : Sleeve or muff coupling Clamp or split-muff or compression coupling Flange coupling. Shanmukha Nagaraj, RVCE. The basic construction of the most flexible couplings consists of two flanges or hubs, which attach to the shafts being couple and a connecting element that may be metallic (such as in disc couplings ), or a sleeve made from elastomeric material such as EPDM rubber, neoprene, Hytrel or urethane, or a mechanical connection (as in a u-joint or gear coupling ). Muff or Sleeve coupling Sleeve coupling with labelled parts. The sleeve is manufactured keeping the diameter of shaft in mind so that the shaft fits perfectly into the sleeve.

System Torque (lb - in) = HP x 60RPM Where: HP (Horsepower) is the actual or transmitted power required by the application (if unknown, use the motor or turbine nameplate rating) and RPM is the actual speed the coupling is rotating.

The Dodge D-Flex coupling features molde non-lubricate interchangeable elastomeric sleeves of EPDM, Neoprene, or Hytrel. Its three-way flexing action accommodates torsional, angular, and parallel misalignment, as well as axial misalignment. 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.

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.

A few service factor ex-amples for standard torque motors are: gear couplings , 1. It is best to consult the manufacturers’ recommenda-tions regarding service factor and torque for proper coupling application.

Like gear couplings, they require lubrication, but allow for flexibility and efficiency at high speeds or at low speeds with high torque. The coupling is suitable especially for drives with uniform to average dynamic loads. Examples of applications are pump drives, ventilator drives or crane running gear.

Coupling Applications and Industries. Further-more, N-EUPEX couplings can be used as add-on couplings, particularly on FLUDEX fluid couplings or ARPEX AKR safety couplings. After spending money on a powerful new pump and the motor to run it,the next big decision is how to connect the two in a way that maximizes their efficiencies and protects them from normal wear and tear. LovejoystraightjawcouplingstypeL,torques0. Universal Joints A universal joint is a linkage consisting of two yokes, one on each shaft, connected by spider as shown on Figure 2. Since universal joints are frequently use and thee r analysis is complex, a separate section is devoted to them following this section.

Muff coupling : This coupling also known as sleeve coupling because it has sleeve or a kind of hollow cylinder. The driven and driving shafts are joined in the sleeve by means of a key. It used to connect pipe to pipe or pipe to swage or nipple. It can be threaded or socket ends types.

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.

One of the most common types of couplings used for transmission of power above 1HP is the gear coupling.

As shown in above figure, gear type couplings consist of two hubs with external teeth that engage internal teeth on a one or two-piece sleeve. The teeth may be straight or curved (crowned). G-Type, which can replace gear couplings and other types that use various shaft coupling methods (Power-Lock, keyway, clamp, etc.) These ECHT-FLEX couplings are ready to meet all of your next-generation coupling needs.

If a clamp type coupling is desire use the letter code “C” after the Spline Code. Fenaflex tyre couplings from to 1675Nm, standard DBSE spacer variant, ATEX approved variant and flywheel version available. HRC, resilient couplings from to 150Nm, available in Taper Lock and pilot bore variants Jaw couplings from 0. Nm with incidental misalignment capacity and quick fit spacer varaint.

The principal mechanism for J- coupling is through bond polarization, but there are situations where a through-space effect seems to be operative. It means a change in the second module will lead to the changes in the dependent module. This type of coupling has a pins and it work as a coupling bolts.

Bushed pin type coupling This is modified form of the protected type flange coupling.
