Definitions

  • the invention relates to a device with a shaft for transmitting torque to a profile tube, of which a longitudinal end region of the shaft surrounds and which is axially displaceable relative to the shaft, wherein a plurality of endless rows of rotating rolling elements are arranged as linear guide elements between the shaft and the profile tube are.
  • a shaft for transmitting torque is known, which is designed as a telescopic steering shaft for motor vehicles. It has an outer, tubular shaft part and an inner, also tubular shaft part, between which balls are arranged as load-bearing rolling elements of ball revolutions. These supporting balls are supported directly on the shaft parts in grooves, so that both shaft parts must be designed as hardened steel parts. Longitudinal grooves are required for the raceways of the supporting balls both in the inner shaft part and in the outer shaft part. The construction is chosen so that corresponding bulges of the shaft parts have arisen in the areas of the grooves. This results in a high cost of materials and manufacturing.
  • the object of the invention is to enable the transmission of torques even from shafts which have lower hardness values than steel shafts, so that light metals, for example, are used as shaft materials or composite materials can be selected.
  • Such a linear guide is intended to enable axial strokes within very wide limits with transmission of the torques without play.
  • This object is achieved in that steel insert bodies are fastened to the shaft, on which raceways for force-transmitting rolling elements of the rotating rows are formed.
  • This solution has the advantage that the shaft can be made lightweight, since only the steel insert body needs to be hardened.
  • the endlessly rotating rolling elements can be balls.
  • a plurality of recirculating ball shoes can be arranged in the longitudinal end area of the shaft, each of which is composed of a hardened insert body made of steel, an outer cage part and an inner cage part, which form a raceway area for force-transmitting balls and two deflection areas and a return channel for returning balls.
  • the steel insert, the outer cage part and the inner cage part can also form two rotations, each with a raceway area for force-transmitting balls and two deflection areas and a return channel for returning balls.
  • two recirculating ball shoes can be arranged diametrically opposite one another.
  • the power transmission from the shaft via the insert body to the profile tube can additionally take place with rollers, for example needle rollers.
  • rollers for example needle rollers.
  • Each insert body can be positively fixed in relation to the shaft with a roller in the circumferential direction, which is inserted into an axially parallel groove of the shaft and a complementary groove formed on the inside of the insert body.
  • each ball race shoe can be axially fixed on the shaft between a molded shoulder of the shaft and a snap ring which is inserted into an annular groove of the shaft.
  • the recirculating ball shoes therefore each consist of a hardened insert body made of steel with ball raceways and two cage parts, which can be made of plastic.
  • the inserted rollers can be used as preload setting elements or as compensation elements for large track tolerances. It is therefore possible to produce the bearing arrangement entirely from non-cutting parts.
  • the resulting tolerances in the ball raceways can be compensated for by sorting the rollers in addition to sorting the balls.
  • angular errors in the raceways can be compensated for, since the steel plates are self-adjusting in the radial direction.
  • FIG. 1 shows a longitudinal section through a longitudinal end region of a shaft surrounded by a profile tube
  • Figure 2 shows a cross section through the shaft according to line ll-ll
  • Figure 3 shows a cross section through the shaft and the profile tube along the line III-III of Figure 1;
  • Figure 4 shows a cross section through the shaft and the profile tube according to line IV-IV of Figure 1;
  • Figure 5 shows the cage parts and the insert body of a recirculating ball shoe, as in a cross section along line V-V of
  • Figure 6 is a view of the outer surface of the recirculating ball shoe
  • Figure 7 shows a partial cross section through the shaft and the profile tube with an insert body in a modified version.
  • a device for the transmission of torques shown in FIGS. 1 to 6 has a shaft 1, the torque of which is to be transmitted to a profile tube 2.
  • the shaft 1 is surrounded by the profile tube 2 in a longitudinal end region.
  • it has grooves 3 which are arranged axially parallel on its outer surface.
  • Two such grooves 3 are arranged diametrically opposite one another on the shaft.
  • Rollers 4 are partially inserted in the grooves 3.
  • Each groove 3 has an arcuate cross-section, the diameter of the arc corresponding to the diameter of the inserted roller 4.
  • the rollers 4 are used for the positive connection of the shaft 1 in the circumferential direction to the profile tube 2.
  • two rollers 4 arranged axially one behind the other are shown in the groove 3.
  • a recirculating ball shoe On each side of the shaft 1, which has a groove 3, there is a recirculating ball shoe. This consists of an insert body 5, an inner cage part 6, an outer cage part 7 and balls arranged between the cage parts. In the assembled state, the recirculating ball shoe contains a track area with force-transmitting balls 8, a return channel with return balls 9 and two deflection areas which connect the force-transmitting track area and the return channel to one another at one end.
  • the insert body 5 of each ball circulation shoe rests with its inner, curved surface on the shaft 1 and here has a groove 10 with which it surrounds the regions of the rollers 4 protruding from the groove 3 of the shaft 1 in a form-fitting manner.
  • the insert body 5 On its side facing away from the shaft 1, the insert body 5 made of steel has two axially parallel raceways 12 for the force-transmitting balls 8. They are the inner raceways of the linear bearing formed by the rotating balls, the outer raceways are formed on the inner surface of the profile tube.
  • the profile tube 2 is thus mounted on the roller 1 so that it can move in the axial direction.
  • FIG. 7 shows an insert body which has an integrally formed driving lug 14 on its inner surface, with which it engages in the groove 3 of the shaft 1 in order to obtain a form-fitting connection of the shaft 1 with the profile tube 2 in the circumferential direction.
  • the driver lug 14 instead of a roller, the driver lug 14 thus engages in the axially parallel groove 3 of the shaft 1.
  • the groove 3 is complementary to the outside of the driving lug 14.

Abstract

Dispositif doté d'un arbre (1) et destiné à la transmission de couples à un tuyau profilé (2) qui entoure une zone longitudinale terminale de l'arbre (1) et peut être déplacé axialement par rapport à l'arbre (1). Plusieurs rangées sans fin de corps de roulement en tant qu'éléments de guidage linéaire sont placées entre l'arbre (1) et le tuyau profilé (2). Selon la présente invention, des pièces rapportées (5) en acier sont fixées sur l'arbre (1). Dans ces pièces sont formées des voies destinées aux corps de roulement des rangées, servant à la transmission de la force. Cette configuration permet d'utiliser une matière présentant une dureté inférieure à celle de l'acier pour produire l'arbre (1).
