Influence of the splash and air-side environment on the sealing effect of radial shaft seals Influence of the splash and air-side environment on the sealing effect of radial shaft seals Sealing environment Project No. 236 The sealing reliability and service life of radial shaft seals is strongly influenced by the direct environment of the sealing element. The aim was to systematically investigate the influences of both the inside and the outside of radial shaft seals. This should result in a catalog of recommendations for favorable environmental design variants. To this end, test equipment and procedures were developed and functional and service life tests were carried out. Final report The temperature of the elastomer material and thus of the sealing element has a decisive influence on its service life. Rule of thumb: a 10 K reduction in temperature can be expected to double the service life. Various bearing types were investigated in the area of the inner environment Connection with baffle and flinger disks at different oil levels, oil supply and bypass channels. and lubrication are influenced by the conveying characteristics of the bearings. The oil level is of secondary importance, bypass channels only have an effect on the operating temperature. Temperature reductions of up to 25% could be achieved. The long-term tests confirmed the results of the short-term tests. Protective measures in the external sealing environment should keep dirt particles and fluids away from the sealing element. Of the measures investigated (protective lip and centrifugal disk), the rotating centrifugal disk proved to be by far the most effective precaution. The other measures are less effective. The evaluation and systematic presentation of the variants now enables the designer to find the most favorable design of the sealing environment for a given type of bearing. The objective of the research project was achieved.
