Sophisticated Technology in the Mars Rover Curiosity: Mission damping accomplished

By Lars Jahnel on Jul 04, 2016

The robust drill on the robot arm of the Mars Rover Curiosity helps scoop rock dust on Mars – a milestone for researchers. A friction spring made of stainless steel dampens the forces generated during the drilling process and prevents any resonance phenomena.

Economical Hollow Shaft Connections

By Ringfeder News on Apr 29, 2016

Many power transmission applications, including gearboxes, require a reliable connection between a solid and hollow shaft. This type of connection, however, only works well if the solid shaft outside diameter and hollow shaft inside diameter have been properly machined to exact dimensional tolerances and finishes. These precision machining factors drive up costs and limit the design freedom of solid-to-hollow shaft connections.

Locking Assembly Eliminates Bending Moment Failures

By Ringfeder News on Mar 18, 2016

Bending moments are an unfortunate fact of life in many power transmission applications. But pulley-and-drum systems have an especially high risk of failure when exposed to these moment loads.

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.

Ringfeder Shrink Discs Help Wind Turbines Transmit High Torques

By Ringfeder News on Feb 18, 2016

Northern Power Systems, a large United States manufacturer of wind turbines, needed a reliable, economical locking device for their systems. In the past, they tried different splined or keyed shafts, but found that these connection methods were too expensive and created a weak point in the shaft connection.

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.

Flange Coupling Sent To The Mines

By Ringfeder News on Mar 20, 2015

Keyways aren’t the only way to couple heavy-duty motor and gearbox shafts. In fact, keyways aren’t even the best way when you consider the alignment and installation difficulties you’ll encounter when installing keyed shaft couplings that may weigh thousands of pounds. A better alternative is to use couplings that employ a mechanical shrink fit around the shafts.
