Description

Patent and auxiliary use austerameldun ^ Bearing bush for plain bearings. '

Me present invention relates to a bearing bush for plain bearings, which may also be designed as a one-sided thrust bearing against mutual axial displacement, as well as against mutual radial rotation, is secured.

To achieve this effect with plain bearings, a & n eich uses Most extensive bearing bushings that have a one-sided collar that serves as a stop when it is pressed into the bore of a bearing bracket and the axial pressure τοη absorbs the flange side. Ub also axial Bridge can accommodate bu is from the opposite direction it is necessary here that on the opposite side of the federal government The bushing is locked, which at the same time also secures the tie against radial rotation, in both directions, intensified will.

The condition for this is in any case that the pressed-in bearing τοη is accessible on both sides, d # The same applies if a bearing to be replaced nut · Is there such a thing, for example Storage at a location that is only accessible from one side, euss a constructive solution must be selected from the outset that makes it possible to when replacing the bearing on both sides of this ■ to be able to ontieren, which often with considerable additional costs production and the amount of work involved in repairs

Finding an effective remedy is the subject of the finding. For example, if the bearing is located in a sheet metal construction, e.g. in a roller, it is the most economical to manufacture AusfUhrungsform that in one forming the outer roller Blochaantel two discs or webs that hold the bearings, are bofeatigt by spot welding aa jacket. During the initial assembly you can Before this spot welding process, the bearings are used against mutual axial displacement, but because of later Renewal of the bearings without a considerably expensive construction will.

The embodiment of the bearing bush according to the invention is designed in such a way that it is pressed into the bore of the bearing bracket from one side, in the roller example cited above, from the respective outside, engages there and is secured against ketal and radial displacement on both sides. can "replacing the used book, by _destroying} derselbcn of the carried one side, then also the injection of the new warehouse book · performed by the ·

The bearing bush / has an abutment collar 2 ", which is provided with at least one recess 2b, in which the pressed-in state" engages the locking cams Ib or Ic and blocks the radial movement. On the side of the bearing bush opposite the collar 2e there is a bevel 2d running around the entire circumference, the smallest diameter of which is smaller than the bearing diameter "D ^H" and the largest diameter of which is greater than the "aß" D " The largest diameter forms the entire circumference of the bush at point 2a.

To install the bushing 2 in the bearing bracket i, the bushing 2 with its annular bevel 2d is brought into contact with the bore 3, Pig.3, and is pressed into it with pressure in the direction of arrow ¹¹ Z ".

The annular bevel 2d hereby presses the segments created by the slots 2c together until the largest diameter, at 2a, can also be introduced into the bearing bore 3, FIG. 4.
