Definitions

  • the invention relates to a roller tappet according to the preamble of claim 1.
  • roller tappets are such. B. from US 5,385,124 A.
  • the roller axis is secured there using circlips that are located in grooves within the roller hubs.
  • the invention is therefore concerned with the problem of securing the axle on which the roller is mounted in a simple manner in the hub bores in the case of generic roller tappets.
  • the main body of the plunger can consist of two or more components connected to one another.
  • the flanks of the locking ring no longer act as a contact surface for the roller axis, but rather the radially inner regions of the locking ring.
  • roller axle according to the invention By securing the roller axle according to the invention with retaining rings which are located in grooves which are introduced on the outside diameter of the roller tappet, processing costs are saved and only one - but larger - retaining ring is required. Another advantage is that only one groove has to be pierced.
  • the securing ring according to the invention does not have to lie in a plane that includes the longitudinal axis of the roller axis, as seen in the axial direction of the tappet, but it can also lie above or below this plane. It is sufficient if the roller axis runs against the locking ring from the inside during a shift in the roller hub. Due to the off-center position of the locking ring, the length of the roller axis and thus the load-bearing length can be increased again.
  • Fig. 1 shows a roller tappet according to the invention in cross section, cut in the direction of the roller axis
  • Fig. 2 shows a roller tappet according to the invention in cross section, cut transversely to the roller axis.
  • the roller tappet 1 consists of a base body 2, a roller axis 3 and a roller 4.
  • the base body 2 has hubs 5 in which the roller axis 3 is mounted. At the level of the hub center, a groove is screwed into the base body 2, in which a locking ring 6 is located.
  • the roller axle 3 is freely rotatably supported in the hubs 5. In the event of an axial displacement of the roller axis 3 in the hubs, it runs against the radially inner surface of the retaining ring. The axial displacement of the roller axis 3 is thus limited by the locking ring 6.
