 · The coupling could transmit motor power to the output end via the magnetic field; therefore, if the load in output end is a fixed value, then the output power of motor is a fixed value too. The ratio between them shall be determined by the air gap and rotating-speed difference at that moment.

Shaft coupling | KSB

The shaft coupling is the connecting element between the electric motor and the pump hydraulic system. Slip-free shaft couplings employed in centrifugal pumps are divided into rigid and flexible shaft couplings. Rigid shaft coupling Rigid shaft couplings are mainly used to connect perfectly aligned shafts. The slightest misalignment results in considerable extra stress on shaft couplings and ...

Coupling Types for Different Applications | Pumps & Systems

 · Oversizing a coupling can result in a reduction in needed flexibility or misalignment compensation, and a coupling that is too large can put additional stresses on the pumps and motors being coupled. On the other hand, a coupling with too much misalignment capacity may be too soft or compliant, which can cause vibration or an unbalanced condition in rotation.


coupling with 5 inch shaft separation should be aligned to be within 0.005 inches. (Note that a 5 inch spacer is the minimum allowed by API 610 (1995) for process pumps.) A failure for this type of coupling is usually limited to the flex element and little or

Pump Couplings – A Comparison | Castle Pumps

When a pump is close coupled, a separate coupling is not required as the motor is directly mounted to the pump on a single shaft. Whilst close coupled pumps benefit from a compact, cost effective design, they are less preferable for heavy duty, high power, continuous use as there is more strain put on the common bearings and the size of the motor is usually limited.

Avoiding Coupling Failure

Back to Basics

 · The coupling spacer on horizontal pumps can then be removed to allow sufficient axial clearance to replace a mechanical seal without moving the pump or motor, or to allow room for the pump "back-pull-out" element to be replaced without moving the motor.

What is Coupling? What are main Types of Couplings?

 · It is another type of rigid coupling so all the conditions are also applicable here like proper alignment of both the shafts and connection should not have any kind of vibrations and jerks. Here we use two flanges one is for input shaft and the other is for the output shaft.

The motor and rotor are usually driven by direct coupling. The crusher generally uses feeding material, and the material enters the gap between hammer and screen. Organic fertilizer crusher is strongly hit by the hammer piece running at line speed under suspended state, and becomes a number of fragments.

Tyre Couplings for mechanical power transmission

The coupling is suitable for ambient temperatures of between -40 C and +120 C.The ELPEX-S coupling is frequently used for diesel motor drives or reciprocating compressor drives. Because the different rubber versions enable the torsional stiffness to be adjusted to meet requirements, the coupling is also suitable for drives which require a specific and preferably pre-calculated torsional ...

Induction Heating Coil Design

1. Type of Heating. In static surface heating, in which the part can be rotated but is not moved through the coil, a coupling distance of 0.060 inch (0.15 cm) from part to coil is recommended. For progressive heating or scanning, a coupling distance of 0.075 inch (0.19 cm) is usually necessary to allow for variations in workpiece straightness.

Clearance And Interference Coupling Fits

 · Steel coupling hubs require an increase of 160 F degrees (90 C) for every mil (0.001 in or 0.025 mm) of interference divided by the hub inside diameter. For example, a steel hub with a 2.125 in-bore with an interference of 0.0015 in will require an increase of 1.5/2.125 x 160 = 113 F degrees (63 C).

Torque Magnetic Couplings

A magnetic coupling is a coupling that transfers force, using a magnetic field rather than a physical mechanical connection. Both torque and linear magnetic couplers are very helpful when one assembly needs a separated operating environment. Fixed Gap Magnetic Coupling. -Face to Face: Face to Face coupler is comprised of disc shaped assemblies.

PRACTICES Shaft Couplings
