Definitions

  • the present invention relates to a device for producing a releasable release from play in a roller bearing, with a roller bearing which has an outer ring, an inner ring mounted on a shaft and a plurality of rolling elements arranged between the inner ring and the outer ring, and with a clamping device mounted on the circumference of the outer ring of the roller bearing for Generating a radial prestressing between the clamping device and the outer ring of the roller bearing that is uniform over the outer circumference of the roller bearing, the clamping device having an axially adjustable clamping element which can be brought into a first orientation, in which the roller bearing has play, and which can be brought into a second orientation, in which the roller bearing is free of play.
  • the invention also relates to a method for adjusting the preload of a roller bearing mounted on a shaft.
  • a hydraulic clamping bush is known from DE 102018123980 Ai. However, this is not disclosed in connection with a roller bearing, but in use with a hub and for producing a non-positive connection between an internal shaft and the external hub.
  • Another clamping bush is known from DE 2639320 Ai. This is used for the non-positive connection of a shaft with a part to be clamped, such as a sprocket, a V-belt pulley or a pinion.
  • a connection between the clamping bush and a roller bearing is not disclosed, in particular not for generating a defined bearing preload.
  • conical roller bearings such as tapered roller bearings, which are installed, for example, in wheel bearings on automobiles
  • the conical or conical running surfaces can only be installed together as a functional unit in the bearing. This always results in an additional summand when calculating the total tolerance.
  • the concentricity on the one hand and the adjustment of the roller bearing play on the other hand can actually be carried out separately from one another.
  • all rotary parts on spindles, shafts, rollers, rotors, etc., together with the inner ring of the bearing can be finally cylindrically machined or calibrated.
  • the invention therefore has the advantage of enabling high concentricity with the simultaneous absorption of high loads. This is also achieved, among other things, by the fact that the bearing preload is not only generated in a two-dimensional bracing plane, but completely around the outer ring of the bearing. As a result, roller arrangements with a backlash-free rotation function are possible on all levels.
  • a defined preload is generated in the roller bearings to be preloaded by infeeding the outside diameter of the bearing outer rings. This achieves a circular, partial or full-circumference contact via the rolling bodies from the static assembly to the rotating assembly.
  • the present invention also enables the operating status to be monitored during operation of the bearing, so that bearing damage or other wear-related failure phenomena can be identified at an early stage.
  • the bearing preload can be adjusted during operation, so that if a change in the bearing preload is detected, for example due to thermal changes, the preload can be continuously readjusted to an optimal value, so that on the one hand optimal operating conditions, for example in the form of very precise concentricity properties, and on the other hand bearing wear can be minimized.
  • a device for producing a releasable clearance clearance of a roller bearing with a roller bearing that has an outer ring, an inner ring mounted on a shaft and a plurality of rolling elements arranged between the inner ring and the outer ring, and with a clamping device mounted on the circumference of the outer ring of the roller bearing for generating a radial preload between the clamping device and the outer ring of the roller bearing which is uniform over the outer circumference of the roller bearing, the clamping device having an axially adjustable clamping element which can be brought into a first orientation in which the roller bearing has play and which can be brought into a second orientation in which the roller bearing is free of play.
  • the device can be used in the field of roller bearings, in roller arrangements such as in a rolling mill or a roll profiling system, in printing presses, rotary process machines, or for grooving, embossing or punching.
  • spindle bearings on machine tools for both tool spindles and workpiece spindles, for example in machining systems, for roll hardening or for knurling. It is also conceivable that the invention is used in spindle bearings for rotators, for example in the field of turbomachinery. Use in the area of wheel bearings is also conceivable.
  • the roller bearing inner rings on the roller are mounted separately from the rolling element with a race on the roller.
  • the surface of the roller with the inner ring of the roller bearing is produced with maximum concentricity in one clamping during production.
  • a tolerance that is as "free of lag" as possible between Bearing race and roller surface required.
  • the conical "shrinkage" of the bearing outer ring with a conical clamping set proposed in the present invention a very precise circular feed is achieved. This is achieved because the individual parts are in direct ground contact and the individual parts can be manufactured very precisely for a specific tolerance range by means of turning and grinding. This is not possible when using conical bearings, since these consist of separately manufactured rolling elements, the manufacture of which is subject to greater tolerance fluctuations.
  • the clamping device can be designed in such a way that it can be pushed onto the outer ring of the roller bearing in the axial direction.
  • the clamping device can enclose the outer ring of the roller bearing in a ring-shaped manner.
  • the clamping device can have a width in the axial direction which is greater than the axial width of the roller bearing.
  • the tensioning element is oversized relative to the tensioning device and/or that there is a state of tension between the two elements.
  • the clamping element can have an axial width which is greater than the axial width of the roller bearing. As a result, the clamping element can be adjusted axially within the clamping device without the clamping element no longer covering the roller bearing.
  • the clamping device has a cavity that extends axially and at least in sections, preferably over the entire circumference of the clamping device, in which the clamping element in the form of a sleeve is accommodated in an axially displaceable manner, with the cavity being able to taper in the axial direction.
  • the cavity can in particular taper linearly.
  • the cavity can have a greater axial width than the clamping element, so that the clamping element can be adjusted axially within the cavity. Provision can be made for the lowest cavity height to be less than the lowest clamping element height. It can also be provided that the maximum height of the cavity is greater than or equal to the maximum height of the clamping element.
  • the sleeve can have two opposite end faces. It can be provided that the sleeve is only adjustable or designed in such a way that a pressure chamber in each case remains between the respective end face and the cavity wall lying opposite it.
  • the sleeve has a sleeve outer surface that is at least partially conical in the axial direction and the cavity has a cavity outer surface that is at least partially conical in the axial direction and points inwards in the radial direction, which interacts with the sleeve outer surface, the conical section of the sleeve surface and the conical portion of the cavity outer surface are aligned parallel to each other.
  • the sleeve can accordingly have a sleeve outer surface which is wedge-shaped in cross-section and the cavity can have a correspondingly shaped cavity outer surface.
  • the sleeve has a sleeve inner surface and the cavity has a radially outwardly facing cavity inner surface abutting the sleeve inner surface, the sleeve inner surface and the cavity inner surface being aligned parallel to the axial direction of the roller bearing.
  • the inner surface of the sleeve and the inner surface of the cavity can lie flat against one another.

  • the device can also have an electrically controllable valve, by means of which the direction of the pressure to be generated and thus the direction of movement of the tensioning element can be controlled.
