End-To-End Coupling Solutions for Cranes and Hoists

By Ross Rivard on Aug 30, 2017

When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some of your options specifically for cranes and hoists.

Balancing of Shaft Couplings

By Frank Richert on Aug 16, 2017

A virtually rotational-symmetrical component may have an unbalance caused by production tolerances or non-homogeneous structure in the material. Such unbalances in a drive system can not only lead to considerable vibrations during operation, but, in the long run, can also lead to failures of individual components or even of the entire drive system. As speed constitutes one of the decisive influences here, balancing is always performed for a certain speed. As a general rule, this is the nominal speed of the drive system.

Couplings in Aeroderivative Gas Turbines

By Thomas Marterer on Jun 07, 2017

Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 rpm to 15,000 rpm. Please see below which couplings are typically used and which are the selection criteria.

How to Specify Couplings for Servo Applications

By Ringfeder News on Mar 15, 2016

Choosing the right coupling style for a servo application can be confusing, but it doesn’t have to be. A better understanding of application requirements such as torque, stiffness, rpm values and shaft misalignment details can help narrow your selection.

Selectively Compliant Coupling Protects Gearboxes

By Ringfeder News on Jun 17, 2015

The big gearboxes that drive cable drums do not come cheap. Yet engineers often
make a design mistake that can shorten the gearbox’s working life. This mistake
involves the use of a rigid, direct coupling between the gearbox output shaft and the cable drum.

New White Paper: Heavy Duty Shaft Coupling Strategies

By Ringfeder News on May 15, 2015

 Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be overengineered with regard to stiffness.
