Rolling bearing housing

The invention relates to a ViäIzlagergehäuse, set up for Kessen the radial force acting on the roller bearing by means of elastically deformable links and an electrical signal transmitter, wherein the elastically deformable member is a perpendicular to the direction of force extending short radial star, which the outer, fastening purposes serving flange with the inner, the roller bearing-bearing holder firmly connects and to the two the sides of the padial bar that are subject to bending stress Strain gauge is occupied.

According to an earlier proposal (G 77 356.5) are two concentric rings linked together over a single one Radial web connected, the outer ring being designed as a mounting flange with mounting holes, while the inner ring as the cold of the rolling bearing under the action of the force to be measured executes a swivel movement and in this way an electrical one Signal transmitter affected.

The roller bearing housing constructed in this way does not give rise to any complaints, provided that there is a sliding or sliding fit between the shaft and the roller bearing, thanks to which the housing can be easily removed from the shaft at any time.

In the case of more firm seats (adhesive seat, driving seat) , pulling off is

made difficult with regard to the fact that yes on the outer ring resp. Splashing is pulled, while the inner ring or holder carrying the roller bearing and resiliently held on the web is already through the slightest Axial pivoting is able to produce a jamming.

Additional construction elements are used to remedy this inconvenience conceivable, such as conical pins or wedges, which are inserted into the device before the removal process for the purpose of blocking the inner ring would have to be used. Such solutions would make the structure more expensive and imply handling.

The invention is therefore based on the object of a roller bearing housing of the type mentioned in the simplest possible way so that the holder is blocked on the shaft when the Bearing or bearing housing is prevented.

The solution to this problem is formed by a erfindungsjremäß second radial web which connects the flange to the holder and which is arranged diametrically opposite the first radial star. The inner ring is then on opposite sides of the outer ring supported, so when the bearing is withdrawn it is lent to sleep The direction of the Larer axis is claimed without a tendency to tilt, which can otherwise lead to jamming on the shaft. There are practically no additional costs associated with this training, as there is only one other processing of a single, internal and outer ring forming disc goes.

In principle, expansion strips can be attached to both radial webs, which interconnect to form an electrical measuring bridge leave.

Furthermore, it can be advantageous for the two radial webs to be different form strong, with at least the weaker radial web is provided with strain gauges.

An exemplary embodiment of the invention is shown in cross section in the drawing.

This drawing corresponds globally to that of the filter proposal. One recognizes again: outer ring or flange 1, inner ring or Balter 2 and radial web 3 with the strain gauges 7, as well as the fixing holes 4, the roller bearing 5 and the stop bolts 6

A new addition is a second radial web 3a, diametrically opposite the web 3. The two webs lie in the same plane 3 - 3a indicated by the reference lines.

The second radial web does not need a strain gauge 7a, however, would be well suited for this. This can be used, for example, to have two measuring strips each 7 and 7a to be connected together to form a full bridge. So this could four measuring strips are all in the middle cross-sectional plane, which has certain application advantages.

If one could speak of a "bending system with Freltrager" in the older proposal, it is now a "clamped beam" which, with the same width, has to be considerably weaker in order to have the same spring constant C = F / f in both cases (fs deflection of the inner ring 2), The drawing shows the two radial webs 3 and 3a in the same thickness, but it makes sense to make them unequal and to attach the strain gauges only to the weaker web (e.g. 3a) in order to increase the measuring sensitivity of the System to increase .

The shape and course of the radial webs do not necessarily have to correspond to the drawing. The shape shown results from the method of manufacture, which is regarded as advantageous, cheap and space-saving, namely the two bores, the distance between which is clearly determined by the strength of the web. The load concentration in the thinnest and easily accessible cross-section is also favorable, because the strain gauges can be used to correctly detect the notch stress. However, other shapes of the radial webs are entirely within the scope of the invention.
