Permanent high stress levels and sub-standard components can lead to reduced equipment performance and reliability as a result of wear and failure of components. No one knows this better than the engineers of drivelines for heavy duty applications like steel mills, cement plants, and mining operations. Heavy shock loads, arduous working conditions and non-stop loading are all factors that can affect the performance of a product in these types of applications. These issues are not only issues for the driven equipment such as table roller drives, conveyors etc., but can create problems in the driving equipment itself, such as the engine or motor. To protect the whole driveline from these factors a coupling is typically used between the driving and driven equipment. The same goes for diesel/gas driven equipment, where a coupling is often used to protect the driven equipment from the harmful effects of torsional vibrations that occur as a result of the reciprocating motion of the diesel/gas engine. Gear, grid and disc pack type coupling are commonly used in these types applications, but a great substitute can be compression type Highly Flexible Couplings. The main advantage being that compression type Highly Flexible Couplings need no lubrication at all in operation. In fact, once installed, there is nothing to worry about for several years in the vast majority of applications. The only replacement part, the rubber elements, can be switched in very short periods of time in most cases (space allowing), and without moving either the driving or driven equipment. In addition the metal components almost never need replacing at all. The CT (compression type) coupling is the latest addition to the large product range of the German-based Voith Company. It is especially designed for industrial applications, e.g. metal manufacturing, mining, cement and Power generating set applications.
