Simplex Bearings
| The functional efficiency of a machine or plant is determined by, above all, the bearing quality on all rotating components. This applies in particular to the ship propulsion line-shafting. For this reason the Simplex bearings were developed especially for this application as short, plain bearings. More than 21,000 of these bearings have left our works to date under the "Simplex" mark of quality. Following consequent further development a range of modern radial plain bearings is available today for a variety of applications. The Simplex bearings have been designed to offer a maximum in functional reliability. This has been achieved by means of a number of design measures; in particular by a short shell length combined with a set screw located at the bearing centre. This set screw allows exact alignment during the installation. By this method it is possible to reduce the danger of edge loading, normally occurring in plain bearings. A spherical centering of the shells with all the known disadvantages is therefore not necessary. As the quality of bearings depends to a large extent on the bearing metal, a material with optimum running properties under emergency conditions has been chosen for metalling the removable shells. Of particular importance hereby is the perfect bonding of the bearing metal with the shell base. This bond is achieved by means of a special metalling process which additionally makes a technically advantageous thin-walled lining possible. Apart from this, the running surface of the bearing must be adequately supplied with lubricating oil to ensure that the bearing functions reliably. The oil is supplied, therefore, via a lubricating ring clamped tight on the shaft and a scraping device fixed loosely in the upper half of the bearing. This device, together with the oil pockets in the bearings shells, ensures that, in the Simplex bearings, the oil supply is maintained at all times, even under low shaft rpm. An effective sealing system at the bearing ends prevents the oil from flowing out and increases the reliability. In special cases we provide our bearings with external lubricating systems which are also suitable for forming hydrostatic lubricating films. If required, we also supply the bearings with additional cooling by means of a water connection. As a standard, Simplex bearings are supplied with a Pt-100 temperature sensor for remote monitoring as well as a local thermometer. The hydrodynamic operation reliability of the bearing is calculated by computer to determine various technical parameters, e.g. lower rpm limit at liquid friction, transition rpm, etc.. For this, the following technical data is needed:
