Abstract

The bearing ring is for the guidance of a shaft, esp. a selector- or cam shaft, in a valve block. The block consists of a metal material, e.g. bronze, and is sealed with profiled rings on either side, relative to shaft and bearing. The ring is pressed into a housing bore, and consists of a plastic e.g. low pressure polyethylene.

Description

Lagerring Bearing ring

Die Erfindung betrifft einen Lagerring zur Führung und Lagerung einer Welle, insbesondere einer Schalt- und Nockenwelle in einem Ventilblock, der aus einem metallenen Werkstoff, beispielsweise Bronze hergestellt ist und beidseitig gegenüber der Welle und dem Lager mit Profilringen abgedichtet ist.The invention relates to a bearing ring for guiding and storing a Shaft, in particular a shift and camshaft in a valve block that consists of a metallic material, for example bronze, and is made on both sides is sealed against the shaft and the bearing with profile rings.

Die Lagerringe der eingangs genannten Gattung weisen insbesondere bei Verwendung in zentralen Steuergeräten in der Verbindung mit einer Hydraulikflüssigkeit, d. h. einer Öl-Wasser-Emulsion den Nachteil auf, daß durch die Verwendung von Werkstoffen verschiedener elektrischer Spannungsreihen im Bereich des Formringes durch elektrolytische Abtragungen Schäden auftreten, die zu Undichtigkeiten im Lagerbereich führen. Die Reparaturen und insbesondere die durch die Reparaturen erforderlichen Stillstandzeiten sind mit überaus hohen Kosten verbunden.The bearing rings of the type mentioned have in particular when used in central control units in connection with a hydraulic fluid, d. H. an oil-water emulsion has the disadvantage that due to the use of materials different electrical voltage series in the area of the mold ring by electrolytic Removal of damage occurs, which leads to leaks in the storage area. the Repairs and in particular the downtime required by the repairs are associated with extremely high costs.

Demgegenüber hat sich die Erfindung die Aufgabe gestellt, einen Lagerring zur Führung und Lagerung einer Welle, insbesondere einer Schalt- und Nockenwelle, in einem Ventilblock zu schaffen, der eine konstruktive Vereinfachung darstellt, der elektrisch neutral ist und der die obengenannten Nachteile auf einfache Weise vermeidet.In contrast, the invention has the task of creating a bearing ring for guiding and mounting a shaft, especially a gearshift and camshaft, to create in a valve block, which represents a structural simplification, which is electrically neutral and which has the above-mentioned disadvantages in a simple manner avoids.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur Lagerung und Abdichtung ein in die Bohrung des Gehäuses eingepreßter Ring aus Kunststoff, beispielsweise Niederdruck-Polyäthylen, vorgesehen ist.This object is achieved according to the invention in that for storage and sealing a ring made of plastic pressed into the bore of the housing, for example, low pressure polyethylene is provided.

Der technische Fortschritt der Erfindung ist im wesentlichen darin begründet, daß durch die Wahl des Werkstoffes unter Fortlassen der üblichen Profilringe eine Abdichtung gegen Austritt der Hydraulikflüssigkeit erzielt werden konnte und daß keine Verschleißerscheinungen sich im Bereich des Lagerringes bemerkbar machen.The technical progress of the invention is essentially therein justifies that by choosing the material, omitting the usual profile rings a seal against leakage of the hydraulic fluid could be achieved and that no signs of wear are noticeable in the area of the bearing ring.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung anhand einer teilweisen Darstellung eines Schnitts durch ein Ventilblock wiedergegeben und wird im folgenden näher erläutert.An embodiment of the invention is based on the drawing a partial representation of a section through a valve block and is explained in more detail below.

Die Zeichnung zeigt teilweise und geschnitten den Bereich eines Ventilblockgehäuses 1. Auf der mit 5 bezeichneten Hohlwelle sitzt in dem Steuergerät die Nockenhohlwelle 6. Die Handhebel 2 sind auf der Welle mit Hilfe einer Sicherungsschraube 3 befestigt.The drawing shows partially and in section the area of a valve block housing 1. The hollow cam shaft is seated in the control unit on the hollow shaft labeled 5 6. The hand levers 2 are attached to the shaft with the aid of a locking screw 3.

Zwischen der Nockenhohlwelle 6 und dem Gehäuse 1 ist zur Lagerung und zur Abdichtung ein Lagerring 7 aus Niederdruck-Polyäthylen eingepreßt. Der Werkstoff hat einen geringen Reibungswert, wodurch der hohe Anpreßdruck leichter zu überwinden ist. Darüber hinaus ist der verwendete Werkstoff ausreichend zäh und besitzt eine hohe Gleitfähigkeit. Da in dem vorliegenden Fall nur geringe Radialbewegungen auftreten, sind die Erwärmungen hinsichtlich einer Materialbeeinflussung zu vernachlässigen. Der Lagerring 7 steht einseitig in Berührung mit der Hydraulikflüssigkeit 9. Nach außen hin ist der Lagerring 7 durch einen Sicherungsring 8 in seiner Position gehalten.Between the cam hollow shaft 6 and the housing 1 is for storage and a bearing ring 7 made of low-pressure polyethylene is pressed in for sealing. The material has a low coefficient of friction, which makes the high contact pressure easier to overcome is. In addition, the material used is sufficiently tough and has a high lubricity. Since only slight radial movements occur in the present case, are the warming in terms of a Material influence too to neglect. The bearing ring 7 is in contact with the hydraulic fluid on one side 9. To the outside, the bearing ring 7 is in its position by a locking ring 8 held.
