Definitions

  • the invention relates to a rolling bearing arrangement with a two bearing rings exhibiting the double row rolling bearing.
  • Such rolling bearing arrangements are used for different applications. In many cases, it is necessary to set the bearing clearance, which should be within specified limits.
  • the bearing clearance can be adjusted only after the assembly of the rolling bearing assembly. In practice so-called shims are used, these are very thin foil-like intermediate layers, which have a certain thickness. Alternatively, a specific bearing clearance can be set by grinding operations (adjustment loops). In certain rolling bearing arrangements, the play can also be adjusted by adjusting an axial force acting on an inner ring or an outer ring of a roller bearing.
  • the invention is therefore an object of the invention to provide a rolling bearing assembly that allows easy adjustment of the bearing clearance by the user.
  • a rolling bearing assembly of the type mentioned that between the bearing rings a different width in the radial direction exhibiting adjustment ring is arranged with an adjustable diameter.
  • the invention is based on the recognition that a simple and user-friendly adjustment of the bearing clearance is possible if the rolling bearing arrangement has an adjusting ring whose diameter is adjustable.
  • the adjusting ring is between arranged the bearing rings, which in turn have raceways for rolling elements, so that the bearing clearance can be set and adjusted by adjusting the diameter of the adjusting ring. This eliminates the need to install shims, which usually had to be made stepwise or iteratively.
  • the setting of the bearing clearance is most easily done by a diameter adjustment made on the adjusting ring. Since the adjusting ring contacts the bearing rings and has a width changing in the radial direction, by adjusting the diameter of the adjusting ring, the distance between the two rows of rolling bearings can be influenced in the tangential direction or in the axial direction to adjust the bearing clearance.
  • a development of the invention provides that the adjusting ring is formed slotted and comprises a screw having a through opening of one end of the setting
  • one end of the adjusting ring could be provided with an external thread which is screwed to a sleeve having an internal thread, which is pushed through the through hole at the other end of the adjusting ring.
  • the adjusting ring has a radially inwardly decreasing width.
  • the cross section of the adjusting ring thus decreases in the direction of the center and increases radially outward.
  • the adjusting ring has one or preferably two opposite axial surfaces which form an angle with the radial direction.
  • the term width refers to the extension in the axial direction. Since surfaces of the adjusting ring contact the two axially adjacent bearing rings, by adjusting the diameter of the adjusting ring due to the radially inwardly reducing width of the adjusting ring the desired setting of the bearing clearance are made. The bearing clearance can thus be easily adjusted by moving the screw of the adjusting ring. In this context, it is particularly preferred that the screw and the threaded bore of the adjusting ring have a self-locking thread, whereby an automatic adjustment is prevented.
  • the adjusting ring of the rolling bearing arrangement it is particularly preferred that it has a trapezoidal or triangular cross-section.
  • the cross section is trapezoidal, so that sufficient space for the threaded hole is present.
  • the threaded bore of the slotted adjusting ring is arranged on the outside of the adjusting ring, the same applies to the through hole on which the screw is supported.
  • the cross section of the adjusting ring can also be triangular.
  • the rolling bearing may be formed as a radial bearing or as an axial bearing.
  • the bearing clearance in the axial direction can be influenced and adjusted by a radial adjustment of the adjusting ring.
  • the bearing rings are preferably formed as outer rings, which are axially spaced from each other and between which the adjusting ring is arranged.
  • the rolling bearing is a thrust bearing, the bearing rings are also axially spaced apart and receive the adjusting ring between them.
  • An axial bearing can z. B. as axial spherical roller bearings, thrust ball bearings, axial taper roller bearings or be designed as an axial needle bearing.
  • the bearing rings each have a running surface formed opposite to the rolling elements.
  • the running surface can be designed, for example, as a segment of a circle or as a spherical cap.
  • the rolling bearing arrangement it is preferred that it has an inner ring on which roll the rolling elements.
  • the rolling bearing is designed as a radial bearing, the inner ring and two as outer rings having trained bearing rings.
  • the inner ring has at its opposite axial ends an enlarged diameter or a board or the like, on which the rolling elements are supported in the axial direction.
  • the rolling elements are preferably designed as balls, rollers, tapered rollers, cylindrical rollers, spherical rollers or needles.
  • the two rows of rolling elements are configured as X-arrangement or as O-arrangement.
  • Figure 1 shows a detail of a rolling bearing assembly according to the invention in a sectional view
  • Figure 2 is a partially sectioned view of an adjusting ring of the rolling bearing assembly according to the invention shown in Figure 1;
  • Figure 3 shows another embodiment of a rolling bearing arrangement according to the invention in a sectional view.
  • Figure 1 is a sectional view showing a rolling bearing assembly 1 comprising a two-row designed as a radial bearing roller bearing with two spaced-apart, designed as outer rings bearing rings 2, 3, between which an adjusting ring 4 is arranged, two rows of rolling elements 5, 6 and an inner ring. 7
  • the two symmetrically shaped bearing rings 2, 3 have concave running surfaces 8, 9, which approximately in the cut view shown in Figure 1 on extend a quarter circle.
  • the bearing rings 2, 3 facing each other inclined surfaces 10, 1 1, which bear against mating surfaces of the adjusting ring 4.
  • the inner ring 7 has on its axial sides 12, 13 running surfaces for the Wälz Eiseni- hen 5, 6 with an enlarged diameter.
  • the rolling elements are designed as balls. In other embodiments, the rolling elements can also be designed as cylindrical rollers, tapered rollers, needles or spherical rollers.
  • the adjusting ring 4 has a trapezoidal cross-section, so that it is arranged like a wedge between the spaced outer rings 2, 3.
  • the adjusting ring 4 allows adjustment of its diameter. As shown in the partially sectioned view of Figure 2, the adjusting ring 4 is slotted, in the region of a gap 16 formed between the two ends 14, 15 is a screw 17 whose shaft passes through a through hole 18 of the end 15 and the thread is screwed into a blind hole 19 of the end 14 of the adjusting ring 4.
  • the adjusting ring 4 has a certain elasticity, by turning the screw 17, its diameter can be adjusted. When screwing the screw 17 into the thread of the blind hole 19, the diameter of the adjusting ring 4 is reduced, by unscrewing the screw 17, the diameter is increased.
  • the adjusting ring 4 acts like an adjustable spring.
  • the rolling bearing assembly 1 shown in Figures 1 and 2 is part of a Radnabentriebs, in which the bearing clearance can be adjusted by simply moving the screw 17.
  • FIG. 3 is a sectional view showing another embodiment of a rolling bearing assembly 20 including a rolling bearing configured as a thrust bearing.
  • the thrust bearing is supported by bearing rings 21, 22, between which there is a row of rolling elements
  • the rolling elements are designed as cylindrical rollers.
  • the adjusting ring 4 has at its axial sides wedge surfaces 27, 28 which abut against outer surfaces of the bearing rings 22, 24, each having the same wedge angle.
  • the first embodiment can be changed by turning the screw 17, the diameter of the adjusting ring 4.
  • the adjusting ring 4 moves radially outward or inward, so that the bearing rings 22, 24 are moved axially apart or towards each other. Accordingly, the adjustment ring in the thrust bearing shown in Figure 3 allows easy adjustment of the bearing clearance.
