Definitions

  • the present invention relates to a shaft bearing assembly for a wind power transmission and a method for mounting rolling bearings on a shaft of a wind power transmission.
  • shafts are supported by bearings so that the shafts can rotate.
  • a movement of the bearing must be prevented axially to the shaft. Another important requirement is that the bearing clearance can be set accurately.
  • a pair of bearings e.g. 1 shows a first mechanism for adjusting a bearing arrangement with tapered roller bearings in a mirror-image back-to-back arrangement (O arrangement), in which case a first tapered roller bearing 1 is shown at one end of a shaft 2 and a second tapered roller bearing 3 at the other end of the shaft 2.

  • a regrinding of the spacer 6 to the correct width can lead to a precise and repeatable bearing clearance adjustment.
  • the position of the inner ring 5 of the bearing 3 is defined by the collar 7 of the shaft 2 and the spacer 6.
  • the bearing 3 To correct the width of the spacer by regrinding, the bearing 3 must be dismantled to get to the spacer 6. This makes the process time consuming and therefore more expensive.

  • the securing of the second roller bearing by the lock preferably causes an axial fixation of the second rolling bearing, wherein an inner ring of the second bearing is secured on the shaft against displacement in an axial direction facing away from the first rolling bearing.
  • An outer ring of the second rolling bearing is secured against displacement in a direction facing the first bearing in the above-mentioned component of the wind power transmission.
  • the rolling elements of the second rolling bearing then secure the inner ring of the second rolling bearing against displacement in the direction facing the first bearing and the outer ring of the second rolling bearing against displacement in the direction away from the first rolling bearing.

In addition, you can adjust the bearing clearance from the side of the second rolling bearing, which is furthest away from the first rolling bearing.
  • the fixing device e.g. an end plate or a circlip, which fixes the first rolling bearing, must not be accessible for mounting or dismounting the locking member.

  • the lock is applied as far as the shaft, as in the Arreit ist is screwed onto the shaft until the second contact surface comes into contact with the abutment.
  • the lock is initially selected so that the shaft has a large axial play after the lock has been applied. According to the invention this axial clearance is measured. Then the lock is removed. In order to achieve a desired axial play of the shaft or a defined preload of the bearings, the lock is now modified or replaced.
  • the measured axial play of the shaft is used. It is thus possible to determine, based on the measured axial play of the shaft, a geometry of the lock which leads to the desired preload or the desired axial clearance.
  • the second rolling bearing is secured with the modified or replaced Arreit ist so that sets the desired preload or the desired axial play.
  • the procedure described has the advantage that the desired preload or the desired axial play can be adjusted independently of dimensional deviations of the components used.
  • the existing dimensional deviations instead flow into the measured axial play of the shaft. This in turn forms the basis for determining the desired geometry of the lock. A compensation of the deviations takes place automatically in this way. Specific measures to take account of the deviations are not required.

  • the spacer 23 and the locking member 24 are designed as a single component, while in the embodiment in Fig. 5, the spacer 23 and the locking member 24 are designed as two separate parts.
  • the detent 16 can be mounted in a manner similar to that described for the previous embodiment, except that in the present embodiment, the spacer 23 and the detent member 24 are mounted and dismounted together because they are made of a single component. If the bearing clearance setting is poor, the lock 1 6 is also degraded in a similar manner and replaced by another lock 1 6 with the correct width.
  • FIG. 7 schematically illustrates another embodiment of the invention. Similar to the embodiments described above, the detent 16 according to this embodiment also includes a spacer 23 and a locking member 24.
  • the spacer 23 and the locking member 24 are designed as two separate parts, and the spacer 23 is located between the bearing 14, more precisely the inner ring 18 of the bearing 14, and the locking member 24.
  • the spacer 23 may have an inverted L-shape.
  • the spacer 23 consists of a first part having a first width and a second part having a second width, wherein the second width is narrower than the first width.
  • the locking member 24 may, for. Example, a lock nut or an end plate or another, a person skilled in the known suitable locking member.
  • the spacer 23 has double contact, namely a contact with the inner ring 18 of the bearing 14 and the other contact with the collar 20 on the shaft 1 1.
  • the lock 1 6 has a first contact surface 17 which is formed by a part of the spacer 23, that is, the widest part or the part with the highest width, and touches the inner ring 18 of the bearing 14.
  • the lock 1 6 also has a second contact surface 19 which is formed by another part of the spacer 23, ie the smallest part or by the part with the smallest width, and an abutment 20, in the present embodiment, a collar 20, on the shaft 1 1 touched.
  • the first contact surface 17 and the second contact surface 19 are both on the same side of the lock 1 6, ie on the side of the lock 1 6, which faces the tapered roller bearing 14.
  • an advantage of a lock 1 6 according to embodiments of the invention is that the bearing clearance can be easily and accurately adjusted.
  • a detent 16 is mounted as described with reference to FIG.
  • that side of the spacer 23, which the second contact surface 19 of the lock 1 6 forms, are reground to optimize the bearing clearance adjustment.
  • An advantage of a shaft bearing assembly 10 according to embodiments of the present invention is that the bearing clearance can be repeatedly accurately adjusted.
  • the shaft 1 1 may be a high-speed shaft, a low-speed shaft and / or an intermediate shaft 1 1 of a parallel transmission stage of a wind turbine transmission.

Abstract

Ensemble arbre-palier (10) comprenant au moins un arbre (11) monté au moyen d'au moins deux paliers à roulement (13, 14). Les paliers à roulement (13, 14) sont montés axialement avec un espace intermédiaire sur l'arbre (11). Le palier à roulement (13) est fixé axialement et l'autre palier à roulements (14) est bloqué au moyen d'un élément d'arrêt (16). L'élément d'arrêt (16) se trouve sur le côté du palier à roulement (14) qui est le plus éloigné de l'autre palier à roulements (13) et présente une première surface de contact (17) qui limite le mouvement d'une bague intérieure (18) du palier à roulement (14) dans au moins un sens, et une seconde surface de contact (19) qui est en contact avec un contre-palier (20) sur l'arbre (11).
