Definitions

  • the invention relates to a single-sided loadable double angular contact ball bearing with the balls of the bearing between them, including races, on the shoulders of which the balls are supported when force is applied.
  • Double angular contact ball bearings are applicable.
  • the object of the invention is to develop a new tandem double angular contact ball bearing which simplifies the production and assembly of the bearings and which improves the relationship between the bearing volume and the load carrying capacity.
  • the invention achieves this by combining several features which are known per se in other types of bearings.
  • the basic feature is that both races are in one piece, a fact that is the case with bearings with filling grooves or the like. is known. This measure therefore enables a very narrow and low construction, especially when the diameters of the ball raceways are different; because then the ball raceways can move closer together, a feature that is also known in other bearings - also with balls of different sizes - but which is particularly important in tandem bearings.
  • These one-piece races not only bring a compact design, but they also have the particular advantage that both races can be ground in with one another so that their apex lines run absolutely parallel and are precisely coordinated with one another. This applies to both raceways of both races. To be able to do this, two further features are required, which are also known for other bearing types, but are particularly useful in combination with the one-piece races.
  • tandem bearing has to absorb particularly large radial and axial forces, particularly high shoulders are required in the direction of force, which in these bearings are applied on one side or are aligned.
  • the shoulders follow the second characteristic
  • At least one of the raceway ends opposite these load-bearing shoulders runs approximately parallel to the raceway outer edge 20 from the apex of the balls assigned to them or it ends in the region of this apex.
  • one of the races with the balls of both or both races with the balls can or can each be fitted with a ball raceway and then the races can be pushed into one another.
  • a one-piece tandem bearing can therefore be produced which can be fully equipped and does not require 30 filling grooves or other auxiliary means.
  • raceway ends can run completely parallel to the bearing outer contour, but they can also be designed to slope slightly or end in the region of the ball vertex 35.
  • the outer race 1 has two shoulders 10, 11, which extend almost to the center of the balls 30, 40, so that they overlap their circumference by approximately 45% of the perpendicular diameter, i.e. almost to the horizontally running ball diameter, that is achieve the optimum shoulder height to be demanded; because 50% or more would be possible with the construction according to the invention, but would not bring any additional advantages.
  • the shoulders 10, 11 can be larger than they are shown, they can also, depending on the application be lower. In this respect, the 45% is only a guideline for optimal louse recordings; Shoulder heights of up to 25% or slightly less are therefore possible within the scope of the invention.
  • the inner contour of the free end 12 of the race 1 runs parallel to the outer contour 13 of this race 1 and starts at the point 41 of the balls 40, so that the race 1 can be pushed over the balls 40 from the left.
  • the race 2 can be mirrored identical to the race
  • the inner contour 22 slopes downward from the apex 31 of the balls 30, that is to say not completely parallel to the outer contour 23 .
  • FIG. 2 shows a variant of the embodiment according to FIG. 1.
  • the races 1, 2 are no longer completely identical or congruent in mirror image as far as the course of the inner contours are concerned.
  • the shoulders 10, 11 and 20, 21 are also present, but designed differently; the reason for this is explained with reference to FIG. 5.
  • the inner contour at 12 also runs parallel to the outer contour 13, but it starts below the apex 41 of the balls 40; this is also explained further in the explanation of FIG. 5.
  • the race 2 is designed differently than the race 1. Its free end 22 is not led to the end of the bearing, but shorter, which saves material and weight. 1 is that the diameter of the two ball tracks 3, 4 is of different sizes. This ensures that the bearing is more compact, the ball races 3, 4 can be closer together. Since the shoulders 10, 11 and 20, 21 are unequally high in this embodiment, the load-bearing capacity of the bearing is somewhat different than in the embodiment according to FIG. 1, but it is also larger here than in the known double-angular contact ball bearings which can be loaded on one side , the relationship between size and load capacity is taken into account.
  • FIG. 3 shows a variant in which the diameters of both the ball tracks 3, 4 and that of the balls 30, 40 are different in size; the ball raceway 4 has a larger diameter than the other and its balls 40 have a smaller diameter than the balls 30.
  • This is one of the optimal designs of the double angular contact ball bearing according to the invention, other variants are possible.
  • the two races 1, 2 are congruent in mirror image, the race diameter is not the same, the ball diameter is the same size.
  • the inner contours of 12 and 22 must run from the apex 31, 41 of the balls 30, 40 parallel to the outer contour or slightly sloping so that the races of one ball raceway are pushed over the balls of the other can be.
  • the ball races 1, 2 are equipped with the balls 30, 40, they can either be pushed together outside the machine parts so that a bearing unit is created, which can either be placed on a shaft and inserted into a housing with it, or into a housing is insertable.
  • both ball rings 30, 40 are inserted into one of the race rings 1 or 2, whereby they are held in the race ring by the somewhat overlapping inner contour of the race ring end 12. Then the other race is inserted.
  • all the types of installation already indicated are possible.

Abstract

Roulement à billes en chevron à capacité portante unilatérale, caractérisé par le fait que le rapport entre la grandeur de construction et l'importance de la capacité portante est plus favorable que celui des roulements à billes connus dont la capacité portante est moindre pour les mêmes dimensions ou qui sont plus grands et plus lourds pour une capacité portante similaire; en outre, la présente invention facilite la fabrication et le montage des roulements à billes en chevron. L'invention permet cela grâce à plusieurs mesures indépendantes en partie les unes des autres, c'est-à-dire grâce au fait que les épaulements (10, 11, 20, 21) des anneaux de roulement à billes (1, 2) peuvent être relevés dans la direction de la force (K) jusqu'à l'optimun et que le profil intérieur (12, 22) d'au moins l'un des anneaux de roulement (1, 2) sorte à partir du point culminant (41) des billes (30, 40) qui leur sont adjointes, presque parallèlement au profil extérieur (13) des anneaux de roulement. Les deux anneaux de roulement (1, 2) peuvent ainsi être équipés entièrement chacun de billes (30, 40) pouvant être ensuite poussées les unes contre les autres. Caractéristiques indépendantes de ce qui précède mais conduisant aux mêmes buts, les diamètres des voies de roulement des billes et/ou des billes peuvent être différents; ces mesures permettent une compacité encore plus grande du roulement à billes en chevron à compacité portante unilatérale.
