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.

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.
