Abstract
The invention concerns a bearing mounting for rotating shafts, in which the main bearings are roller bearings and the shafts turn at more than ca. 3000 r.p.m. With the aid of auxiliary bearings, these main bearings are loaded radially according to the invention in order to prevent the rollers and roller cages of the main bearings from rotating with only a reduced r.p.m. in the case of nonloaded rotating shaft and being suddenly accelerated with a sudden loading of the shaft and thus wearing prematurely. This radial load results from the fact that the auxiliary bearings are maintained eccentrically shifted.
Claims10
A bearing assembly for a revolving shaft, especially for a roller shaft, comprising a bearing housing, at least two main bearings that transfer radial and possibly axial operating forces mounted in said bearing housing and spaced apart axially along said shaft, at least one auxiliary bearing in said housing shifted in the radial direction eccentrically to the main bearings or held in a displaceable manner, characterized in that the main bearings of the shaft, rotating at more than about 3000 r.p.m., are designed as roller bearings and that the eccentric auxiliary bearing or bearings load the main bearings with a radial pressure that eliminates only the backlash of the main bearing roller bodies and cages during the idling of the shaft.
