Alignment Requirements: Flexible couplings can handle slightly misaligned shafts. Rigid couplings are torsionally stiff and can't tolerate 

When using short-flex coupling tolerances, the centerline of rotation of each machine is aligned at the coupling center, which is the center 

Precise alignment of the coupling halves contributes to a long service life of the flexible coupling elements. Please see the table below for the 'Max- imum 

FLEXIBLE COUPLING > Made in steel fully turned with standard treatment of phosphating. > Simple manufacturing. > High angular misalignments possible. > Elastic element with an internal nylon weave for high reliability. > Possible to maintain without the need to move the hubs.

17/04/  · Coupling Tolerances. By Brian Shanovich. There is an ongoing debate on what tolerances are acceptable when aligning your rotating equipment. The debate falls on the

Flexible Shaft Couplings. In many cases machine designers give limited thought to flexible shaft couplings. They devote their time to the more expensive components, overlooking the fact that the performance of a machine is only as good as the connections of its shafts. Reliance is fully aware of the importance of the shaft coupling and that

Several factors should always be taken into consideration when looking to specify flexible shaft couplings. These are torsional stiffness, backlash, torque, life and attachment system. All of these have bearing on coupling selection.

Flexible coupling, The term Flexible Coupling is often interpreted in different ways. We believe this term is used to describe the couplings elastomeric properties, i.e. having an elastomer or elastic type element. Typically this element is made of a rubber or urethane compound or derivative.

Flexible couplings transmit torque from one shaft to another and are particularly useful in cases where a limited amount of misalignment of the shaft is unavoidable. Elflex flexible couplings are cushioned drive type couplings that transmit the torque through rubber bushes which have an excellent capacity to absorb shocks. Cone Ring couplings,

Sometimes one flex-rigid coupling is used in series with another flex-rigid coupling at a distance to allow much more parallel misalignment. While gear couplings will normally provide from ½°

Rexnord® Thomas® Flexible Disc Couplings Overview A flexible coupling is a device used to connect the ends of two shafts, transmit torque, and at the same time, accommodate slight misalignments which develop in service . The primary functions of all flexible couplings are: 1 . To transmit power from one shaft to another, efficiently and

Flexible couplings are designed to protect shaft support bearings from destructive radial and thrust loads arising from misalignment and axial motion. In effect

Flexible couplings couple or connect rotating members such as motors and drive shafts while allowing misalignment in either angular or parallel offset orientation. Flexible coupling types include: Sliding block, Metal contoured diaphragm, Roller or silent chain, Steel grid, Coil spring, Wafer or flexible disc, Schmidt, Beam or flexured (helical)

The primary torsional coupling uses a resilient elastomer as the flexing medium. All of the couplings described in the elastomeric section of the handbook have been used on torsional service with varying degrees of success. The elastomeric types described in the following section are the couplings with the best attributes for torsional service.

Couplings can take misalignment? An often quoted comment is “why bother to align the machine when it is fitted with a flexible coupling designed
