Definitions

  • the invention is based on a bearing seat according to the preamble of the main claim. It is known to insert an intermediate bushing into the bearing recesses of a housing, for example if it is made of aluminum or the like in the region comprising the bearing recess, which is seated with its outer wall in the bearing recess and receives the outer surface of the bearing with its inner wall , for example a roller bearing outer ring. Such intermediate bushings are also known as fitting rings and are mainly used to ensure a good bearing seat life due to their dimensional accuracy and above all to compensate for tolerance differences, even if significant temperature shifts must be expected during operation. Since the invention is preferred for the bearing seat design in three-phase generators for motor vehicles and.

  • the invention solves this problem with the characterizing features of the main claim and has the advantage that, due to the at least one thinning of the material in the axial direction of the fitting ring, i.e. in the longitudinal direction, the bushing or fitting ring material can evade in the radial direction, so that the fit ratio se more precise and the press-in forces become smaller; Furthermore, immediately in the area of the relevant bearing hub, i.e. during the assembly, calibration or work was carried out and, under certain circumstances, there was even no prior pressing operation (i.e. a corresponding calibration step), and the intermediate bushing was simply inserted during the rotor assembly Forces of rotor assembly can be significantly reduced.
  • the two embodiments of the invention represent in each case approximately end regions of solutions characterizing the invention, intermediate solutions being of course possible; while one can or should calibrate in the bearing hub during assembly when arranging grooves and depressions in at least one Prust barnmes water of the socket, when arranging a longitudinal slot in the socket is only that. Wall thickness crucial; The inner and outer diameter of the bushing are obtained during final assembly by contacting the recess in the bearing hub, ie the end shield or. on the outer ring of the ball bearing.
  • the press-in forces for the ball bearing to be used are also reduced ger.
  • the reduction of the press-in forces. is generally to be attributed in an advantageous manner to the fact that the material of the bushing or the fitting ring can flow radially in a shorter way for deformation, whereas with smooth fitting diameters, particularly high radial pressures in the hub area necessarily occur on both sides, so that the material of the bushing then deviates approximately axially can.

  • Fig. 1 the area of the B-bearing plate 10 of a three-phase generator 11 is shown in more detail; Usually, this end shield is made of aluminum, the bearing seat bushing is designated 12 and sits in a bearing recess 13 (aluminum bearing hub) of the B-end shield 10.

  • FIG. 4 shows a detail of an area designated by Y in FIG. 2, and it can be seen that, taking into account an already relatively exact dimensional accuracy already during bushing production, preferably in the injection molding process, the grooving is not very profound and, um to be able to make a numerical specification, the distance between the depressions and the outer diameter of the bushing can be, for example, between 15-30% of the bushing wall thickness.
  • an average fitting diameter that is to say averaged between a respective increase and a respective depression of the grooving, can also be envisaged in the manufacture of the bushing. This ensures that deformation work is performed in any case, which benefits a secure fit. Such a grooving will definitely make the fit conditions much more precise; one avoids the deformation of the hub directly when carrying out the calibration process in the respectively assigned bearing hub and achieves considerably lower press-in forces on the one hand into the bearing hub and on the other hand of the ball bearing outer ring into the bush.
  • plastic bushing that forms the bearing seat to use the plastic bushing completely without calibration process, by inserting it - with wall thickness that is as precisely as possible - during final assembly between the outer race of the ball bearing and the bearing hub of the housing, for example by first moving the bushing pulls over the outer ring of the ball bearing and then presses the whole into the bearing hub (bore 13) of the housing.
  • the larger expansion coefficient of the plastic used in each case is able to match the play conditions between the aluminum bearing hub and the roller bearing.

Abstract

Dans le montage (15) d'un roulement, en particulier pour des alternateurs à courant triphasé, un coussinet (12, 12', 12''), de préférence en plastique, aminci dans le sens axial, ou longitudinal, est introduit entre l'évidement (13) formé dans le carter (10) pour le roulement (coquille B de coussinet) et la surface extérieure (18) du roulement à bille (16) à monter dans l'évidement pour le roulement. L'amincissiment peut prendre la forme d'une crénelure (Fig. 4) à arêtes et creux s'étendant sur au moins un diamètre d'ajustement du coussinet, ou d'une fente longitudinale (25) coupant la forme annulaire du coussinet. Cela rend le calibrage plus facile, étant donné que le matériau déplacé peut pénétrer dans le creux, ou permet de renoncer à tout procédé de calibrage.
