Definitions

  • the invention relates to a rolling bearing comprising an outer ring and an inner ring with respective running surfaces for arranged between these Wälz- body.
  • roller slip In roller slip, a single or multiple roller does not support the load; in case of cage slippage, which can occur with double bearings, a complete roller ring does not support the load.
  • slippage should be avoided.
  • rolling bearings that require a precise game setting in use, which is technically complicated manufacturing technology and installation. Exists such a bearing, for example, by temperatures prevailing in the operation temperature expansion, this results in a Spielver change, too much strain can lead to high radial biases, leading to a high lubricant stress and thus to a shortening of the service life or a spontaneous failure Hot run can lead.
  • the invention is thus based on the problem to provide a rolling bearing in which a slip largely excluded and the game setting is simplified.
  • two or more clamping elements are provided with particular advantage, which are integrated into the running surface of one of the rings, so ultimately form a part of the tread. These clamping elements are radially movable against a restoring force.
  • the clamping elements are biased radially inwardly by this restoring force
  • the clamping elements are pressed radially outward over the restoring force. In any case, they are biased towards the rolling elements. If, for whatever reason, in principle, one or more rollers would not run on both, but only on one running surface, then it is ensured via these tensioning elements that this or these rolling elements are still in contact with it Running surface stand, as the one or more of the clamping elements in this case out of the tread feathers out in the WälzConsequently Symposium and form the tread for the or the "slipping" rolling elements.
  • the game setting is simplified. Because as a result of the spring travel of the clamping elements in the region of the rolling elements consequently a larger game can be bridged, that is, it is ensured via the exposed from the respective tread clamping elements that the rolling elements always on the opposite tread as well as on the clamping elements to run.
  • the clamping elements themselves are preferably designed as arc segments and received in a formed in the tread, groove.
  • This groove can be radially limited.
  • Trained as arc segments clamping elements complement each other preferably in the circumferential direction to form a ring, so that all rolling elements can be biased on the arc segments.
  • each clamping element is coupled with at least one movably received in a radial recording and acted upon by the restoring force pressure piece in the invention.
  • a pressure piece may be a preferably cylindrical pin, which in a corresponding radial bore, which passes through the outer or inner ring and in the groove in which the arc segments are received, opens, executed.
  • the hole is also cylindrical.
  • an arcuate pressure plate which is quasi designed as a relatively wide ring segment and is inserted in a corresponding slot receiving, which in turn opens in the groove receiving the arc segments.
  • annular spring surrounding the respective outer sides of the respective ring is advantageously provided.
  • a corresponding receiving groove may be provided on the outer ring or on the inner ring on the opposite side of the respective running surface into which the annular spring is snapped.
  • This annular spring loads the plungers, no matter how they are formed, about which thetientvor- tension is set. This ensures that each rolling element is always sufficiently loaded and no cage or roller slip occurs.
  • the bias can also be adjusted accordingly. By an appropriate vote of the spring and the radial play and too much pre-tension can be avoided, the bearing is always free of play, so that the necessary backlash-free guidance is ensured, for example, when used to support a machine tool spindle.
  • hydraulic or pneumatic tensioning means that is to say corresponding elements which are acted upon hydraulically or pneumatically and interact with the pressure pieces.
  • the clamping elements in the depressed in the tread position lie flat and edge-free in the tread. This can be ensured by the fact that after inserting the clamping elements in the tread this surface is again ground, so that the tread including the arc segments is ground again, creating a completely flush integration of the arc segments in the tread without any remaining edges and the like is obtained.
  • corresponding clamping elements or arc segments are integrated at both ends of the tread. If the rolling elements are rollers, they are therefore supported at both ends. In principle, however, it is also conceivable to integrate the clamping elements only in the center of the running surface, seen axially, and thus only to perform a central support.
  • Fig. 1 shows an inventive rolling bearing in section
  • Fig. 1 shows an inventive rolling bearing 1, consisting of an outer ring 2 with a tread 3, an inner ring 4 with a tread 5 and a plurality of arranged between these treads rolling elements 6.
  • the rolling elements 6 are as known in a cage 7 out.
  • clamping elements 9 are integrated here at the two axial ends of the tread.
  • These clamping elements 9 are here designed as arcuate segments 10, so as a metallic arcuate ring sections, wherein at least two such arc segments 10 are provided around the circumference, which complement each other to form a complete ring. It would also be conceivable, in principle, to provide three such arcuate segments 10 120 ° or four arc segments 90 °.
  • the arc segments 10 are received in a respective groove 11 which is incorporated in the tread.
  • the groove is radially bounded so that the arc segments 10 can only spring in until their running surface 12 is completely flush with the running surface 3 of the outer ring 2, that is, they are complemented.
  • the bore 14 widens to a groove 17, in which a clamping device 18, here in the form of an annular spring 19, is added.
  • This annular spring 19 presses on the pins 16, which in turn press on the arc segments 10.
  • the arc segments 10 are stretched against the rolling elements 6, they are, seen radially, pressed inwards and thus pushed out of the tread 3.
  • the rolling elements 6 are thus biased by these spring-loaded clamping elements 9 is biased against the tread 5 of the inner ring 4.
  • roller or cage slip can be avoided by this, even if one or more rolling elements 6 do not run on the running surface 3 of the outer ring 2, but the rolling elements 6 run at least on the running surfaces 12 of the arc segments 10. So there is always a bearing contact in the tread 3 given.
  • the receptacle 13 would then be designed as a radial slot, in which the pressure piece is inserted. This can realize a larger smoother contact zone between the pressure piece 15 and the arc segment 10.
