The shaft is made of alloy steel, flanges out of cast iron and bolts out of steel. Rigid coupling is a type of shaft coupling that is used to connect two shafts together at their ends for the purpose of transmitting power. These couplings are used to connect two aligned shafts at their ends to transmit power. transmit power (torque) from one shaft to the other causing both to rotate in unison at same RPM, & to compensate for minor amounts of misalignment and random movement between the two . The coupling is keyed to both shafts with bolts. The History of Rigid Pipe Couplings. Flange couplings used to connect shafts of the same or different diameters. ⦁ It should be easy to assemble or disassemble.⦁ Flange coupling should transmit torque and power.⦁ Maintain proper alignment.⦁ Minimize the shock loads transmission. Over 50% of electric motor failures are bearing related and the majority of those are due to improper lubrication. #2 Sleeve or Muff Coupling. In contrast to rigid couplings, flexible couplings (the focus of this article) have an integrated flexing element or design component that allows for some degree of misalignment handling & management.

The Bauer AsepticDrive is a combination of a motor with a smooth surface (without cooling ribs and fan) and a gearbox from the renowned Bauer 2000 range. Cast iron experiences less solidification shrinkage. Shaft couplings are available in different sizes and material finishes. The grooved pipe couplings joining the riser piping sections are rigid, while those at the top on the first horizontal pipe are flexible, as shown in Figure 2. The right choice of the bearing depends on some essential factors such as frictional resistance, load-carrying capacity, mounting complexity, or the rotational speed. Example 10 - Example of rotor connected by a rigid mechanical coupling with parallel misalignment.¶ In this example, we use a finite element (FE) model to represent the rotor that is available as a test rig in LMest - UFU for demonstrating the results obtained when we have a misalignment defect present in the system. Compact & Low Moment of Inertia The axial length is maximally reduced, allowing for more compact design. It does not absorb vibrations leading to the replacement of the parts.

Easy assembling and dismantling without changing the position of the shafts.It can be used to connect two shafts of heavy transmission at moderate speed. For high power transmission or high speeds, these sleeves coupling are not recommended. Just a short overview for our customers. Browse Victaulic rigid couplings product listings for pipe joining & fire protection. Compared to other types of rigid couplings, set screw couplings are the most cost-effective option. These can transmit the highest amount of torque from one end to the other end. There are several characteristics that you need to pay attention to when selecting a motor: voltage, current, torque, and velocity (RPM). roller chain coupling. Because of the nature of flexible pipe couplings, systems that utilize a large number of them will need additional supports and ways to accommodate or prevent the linear expansion of the system when pressurized. Set screws can leave dents or dimples in the shaft or keyway, Equally distributed load along the circumference, A little Angular misalignments accommodation, Can allow for radial misalignment accommodation, So, there you have every fact about the different, . To positively transmit torque, the coupling incorporates axially fitted keys and split circular key rings or dowels, which eliminate frictional dependency for transmission. These couplings are used to connect two aligned shafts at their ends to transmit power. The outer diameter of the sleeve should be 2 times the diameter of the shaft + 13mm additional on diameter and the length of the sleeve should be 3.5 times the shaft diameter. The rest is easy. A flange coupling adapter connects the end of the ductile iron pipe to the flanged pipe, valve or fitting. Shaft keys transmit torque from the shaft to the coupling hubs, and set screws keep the coupling from sliding along the shaft. Generally, the shaft orientation, efficiency, speed and torque determine which type should be used for a specific application. . There are three main types of rigid couplings: sleeve, flanged and clamped.
