KRW as a strong development partner in engineering
KRW accompanies you with well-founded know-how in the development of customized special solutions according to individual requirements. In direct cooperation between our application engineering department and the customer, technical possibilities are checked, coordinated and realized. Our engineering expertise has already helped to conserve resources and realized cost savings in numerous projects without considering only the bearings, but rather the complete machine.
Fig.1 - Bearing concepts for a 3 cylinder crankshaft bearing
How comprehensive this cooperation can be, is shown by the calculation example of a crankshaft bearing in a MULTISAFE® pump of the German pump manufacturer FELUWA. Fig. 1 presents the three possible bearing concepts on the basis of which the investigation was carried out. The aim was to check the number of central bearing positions that were actually required.
Shaft calculcation for bearing concept
The original crankshaft bearing could be optimized so that in the future there is no need for the use of the previously used center bearings. This not only achieves a significant shortening of the costly crankshaft and housing, but also our customer benefits from savings in terms of material usage and assembly costs of the bearings.
Shaft calculation for bearing concept (example for bending line)
In addition to project-related calculations, our engineering portfolio also includes FE analyzes, rolling bearing vibration analyzes in accordance with VDI 3832, as well as bearing reports and trials of rolling bearing components. We support our customers from bearing development to implementation.
