Definitions
- the invention relates to a roller tappet according to the preamble of claim 1.
- roller tappets are z. B. from US 5,385,124 A known.
- the backup of the roller axle takes place there over Retaining rings, which are inside the roller hubs in grooves lie.
- the invention therefore deals with the problem in generic roller tappets the axis on which the role stored in a simple manner in the hub bores too to back up.
- the main body of the plunger may well from two or more interconnected components.
- roller axle according to the invention By securing the roller axle according to the invention with Circlips lying in grooves on the outer diameter the roller tappet are introduced, processing costs saved and it is only one - but larger - circlip needed. Another advantage can be seen in the fact that only one groove stung must become.
- the circlip according to the invention does not have in axial Direction of the pestle are seen lying in a plane that the Longitudinal axis of the roller axis includes, but he can also lie above or below this level. It is sufficient, when the roller axis in a shift in the roller hub starts from the inside against the circlip. By the eccentric position of the locking ring, the length of Roll axis and thus the bearing length increased again become.
- the roller tappet 1 consists of a base body 2, a Roller axis 3 and a roller 4.
- the main body 2 has Hubs 5, in which the roller axle 3 is mounted.
- On Height of the hub center is in the main body 2 a groove screwed, in which a locking ring 6 is located.
- the Roller axle 3 is freely rotatably mounted in the hubs 5. at an axial displacement of the roller axle 3 in the hubs this runs to the radially inner surface of the locking ring on. The axial displacement of the roller axis 3 is therefore limited by the retaining ring 6.
