The primary objective of a shaft coupling is to connect with two pieces of rotating equipment while permitting for …
Copyright © 2020, Lovejoy, LLC. (Also called reducing coupling or reducer coupling), There are two manufacturing methods: Forging and Casting, Forging process: Raw material as steel ingot or a round bar, heating and forging. Coupling fall into two main categories: Material Flexing and Mechanical Flexing. Clamped or compression rigid couplings come in two parts and fit together around the shafts to form a sleeve. Octal Pipe Fittings is engaged in providing completely piping solutions for industrial companies. They offer more flexibility than sleeved models, and can be used on shafts that are fixed in place. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications. Generally, three, four, or six bolts are used. It is a joint that helps to extend or terminate a pipe. One coupling is placed … Half coupling is only threaded or socket weld at one end, and the other end can be welded directly into the operation of the pipe to form a branch connection. Constant velocity.
In an unprotected type flange coupling, as shown in Fig. Steel Pipe Elbow.

Couplings, serving as vital transmission parts, are no exception to meet higher and more stringent quality requirements needed for the steel plant’s equipment and machinery.
For carbon steel pipe coupling the material standard is ASTM A105, manufacturing standard ASME B16.11. Contact Us Now for an Immediate Offer! Requirements of a good shaft coupling; Different types of Shaft Couplings? (There are also casing and tubing coupling material in carbon steel, referred API 5CT J55/K55, N80, P110 etc). The Jaw Type couplings from Lovejoy are offered in the industry’s largest variety of stock bore/keyway combinations. COUPLINGS 3.0 Types of Flexible Couplings Most small to medium size couplings are basically one of three types. Defining a coupling constraint requires the specification of the reference node (also called the constraint control point), the coupling nodes, and the constraint type. 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. Related Products. Lovejoy Jaw Type couplings generally consist of two hubs (available in sintered metal, aluminum, bronze, steel, stainless steel, and ductile iron), and an elastomer element, known as a spider or cushion (materials available include NBR SOX rubber, Urethane, Hytrel®, and Bronze). After that do threading or not as required. Unprotected type flange coupling. Lovejoy’s Jaw Type couplings are available in 24 sizes from a minimum torque rating of 3.5 in–lbs (0.4 Nm) to a maximum torque rating of 170,004 in–lbs (19209 Nm) and a bore range of .125 inches (4.45mm) to 7 inches (178mm). Couplings correct for an inability to produce or maintain perfect alignment in coupled machines. On the other hand, full coupling have both ends of threaded or socket welded. Rigid Couplings; Flexible Coupling; Coupling maintenance and failure; What is shaft coupling? Shaft couplings, collars, and universal joints are parts that connect equipment to transmit power and help protect against shock, vibration, misalignment, backlash, and overload. Clamp or split-muff coupling. Connection Threads: BTC, EUE, NUE, Premium. Jaw couplings, sleeve couplings, and tire couplings do not require lubrication and are commonly used on electric motor applications, such as gearboxes, conveyors, and medical equipment. A name must be assigned to the constraint and may be used in postprocessing with Abaqus/CAE (Threaded full coupling is same shape but just ends in threaded). (Applied for carbon, alloy and stainless steel material), Casing process: Melting the steel ingot and pouring it into a fixed mode and cooling it. The basic construction of the most flexible couplings consists of two flanges or hubs, which attach to the shafts being coupled, 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 … This website or its third-party tools use cookies. 2655 Wisconsin AvenueDowners Grove, IL 60515. Where in North American term, a coupler is a double female while a nipple is double male. Coupling designs are many only the principal ones are detailed above. Couplings and Their Types. Other coupling types include meshing tooth, or Hines, designs, pin and bush couplings, and spline couplings.
Couplings are mechanical elements that ‘couples’ two drive elements which enables … We are located in China, intended to build as an one-stop purchase center for pipes and fittings, equipped with muti-base inventory in north of south of the China port, committed to provide most urgent material in the first time. The coupling constraint associates the reference node with the coupling nodes. This type of coupling is mostly used to couple electric motors and machines. Email: info@octalpipefittings.com. Half Coupling: Joint one end anther end will be welded directly to the run pipe. The flange couplings are of the following three types : 1. (Or send inquiry to info@octalpipefittings.com), ASTM A234 Carbon and Alloy Steel Fittings. They consist of short sleeves surrounded by a perpendicular flange. Lovejoy’s standard bore program covers AGMA, SAE, and DIN bore/keyway and spline bore combinations.
And for all of these types for different applications, the are ranges: Full Coupling: Joint two pipe or joint pipe to a nipple. each shaft is keyed to the boss of a flange with a countersunk key and the flanges are coupled together utilizing bolts. Inquiry Now!
3.1 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 used, and thee r analysis is complex, a separate section is devoted to them following this section. They generally are large enough so that screws can pass all the way through the coupling and into the second half to ensure a secure hold. Phone: +852 8191 1516
In case of the threaded coupling, the coupling ends normally in female of NPT (National Pipe Threads) or in male and female BSP (British Standard Pipe Threads). So there are several variation types:Coupling has one end threads in NPT another end in BSP, then an adapter shall be used during installation.Coupling has one end in socket weld, another end in threaded socket.One end in bigger NPT another in smaller dia NPT.
Lovejoy’s standard bore program covers AGMA, SAE, and DIN bore/keyway and spline bore combinations. Coupling Applications and Industries. Steel pipe coupling is a very short length of tube used in piping or plumbing, it usually refers to the socket weld or a threaded on one or both ends that allows two tubes connected together. Jaw Type Couplings Digital Catalog & 3D CAD.
Flanged rigid couplings are designed for heavy loads or industrial equipment.
Lovejoy’s Jaw Type couplings are available in 24 sizes from a minimum torque rating of 3.5 in–lbs (0.4 Nm) to a maximum torque rating of 170,004 in–lbs (19209 Nm) and a bore range of .125 inches (4.45mm) to 7 inches (178mm). Types of Couplings. A shaft coupling is a device that is used to connect two ends together for the goal of transmitting power. This article describes what is a coupling, types of couplings, rigid couplings, flexible couplings, universal couplings, Hookes coupling, Pin Bush Coupling, Flanged Coupling etc. Figure 1: The four types of misalignment that couplings can accomodate. We will reply you in 2 hours during support time!
For stainless steel coupling material standard is ASTM A182, grades in F304/L or 316/L, Socket weld couplingThreaded couplingOne end in socket weld another end in threaded.
