Description
Die vorliegende Erfindung betrifft ein stossdämpfendes Lager für Uhren und feinmechanische Geräte.The present invention relates to a shock absorbing device Warehouses for watches and precision mechanical devices.
Erfindungsgeraäss wird bei einem solchen Lager vorgeschlagen, daß ein Lagerkörper aus Kunststoff in Forin einer mit ihrem Aussenurafang an einem Lagerhalter befestigten dünnen Ringscheibe vorgesehen ist, die eine zentrale Verdickung aufweist, in welcher ein Sackloch zur Aufnahme des Endes der Welle ausgebildet ist, wobei die axialen Stösse, denen die Welle ausgesetzt ist, durch elastische Verformung des den zentralen Teil des Lagerkörpers umgebenden dünnen ringförmigen Teiles aufgenommen werden, während die seitlichen Stösse durch elastische Verformung der Masse des zentralen dicken Teiles des Lagerkörpers selbst aufgenommen werden.According to the invention, such a bearing is proposed that a bearing body made of plastic in the form of a thin washer attached to a bearing holder with its outer surface is provided, which has a central thickening in which a blind hole for receiving the end of the Shaft is formed, the axial shocks to which the shaft is exposed, by elastic deformation of the the central part of the bearing body surrounding thin ring-shaped part, while the lateral impacts by elastic deformation of the mass of the central thick part of the bearing body itself.

Weitere Einzelheiten und Vorteile der Erfindung sind nachstehend anhand eines in der Zeichnung dargestellten bevorzugten Ausf iihrungsbeispiels näher beschrieben.Further details and advantages of the invention are shown below with reference to one in the drawing preferred embodiment described in more detail.
Die einzige Figur der Zeichnung ist ein axialer Schnitt durch ein Lager für die Unruhwelle einer Uhr.The only figure in the drawing is an axial section through a bearing for the balance shaft of a watch.
Das dargestellte Lager weist einen Halter 1 aus Messing auf, in welchem eine zentrale Öffnung 2 für den Durchtritt der mit 3 bezeichneten Welle vorgesehen ist. Der Lagerkörper besteht dabei aus einer dünnen Ringscheibe 4 aus Kunststoff, die mit ihrem Aussenumfang bei 4a an dem Halter 1 befestigt ist und einen massiven zentralen Teil 4b aufweist, in dem ein das Ende der Welle 3 aufnehmendes Sackloch 5 ausgebildet ist.The bearing shown has a holder 1 made of brass, in which a central opening 2 for the passage of the with 3 designated shaft is provided. The bearing body consists of a thin washer 4 made of plastic, which is attached to the holder 1 with its outer circumference at 4a is and has a massive central part 4b in which a blind hole 5 receiving the end of the shaft 3 is formed.
Der zentrale dicke Teil 4b des Lagerkörpers weist eine kegelstumpf förmige Auflagefläche 6 auf, die mit einem Sitz 7 des Halters i von entsprechender Form in der Weise zusammenwirkt, daß sie die Zentrierung des Lagerkörpers gegenüber dem Halter gewährleistet.The central thick part 4b of the bearing body has a truncated cone-shaped bearing surface 6, which is connected to a seat 7 of the Holder i of a corresponding shape cooperates in such a way that it centers the bearing body relative to the holder guaranteed.
Der Lagerkörper 4 ist an Ort und Stelle in dem Halter 1 geformt.The bearing body 4 is molded in place in the holder 1.
Bei axialen Stössen, die die Welle 3 erfährt, verformt sich der ringförmige dünne Teil des Lagerkörpers 4 und sein zentraler Tei} 4b trennt sich von dem Halter 1, wodurch diese Stösse elastisch gedämpft werden. Was die seitlichen Stösse, die die Welle 3 erfährt, anlangt, so werden sie durch die Eigenelastizität des massiven Teiles 4b des Lagerkörpers 4 aufgenommen.In the event of axial impacts experienced by the shaft 3, the thin annular part of the bearing body 4 and its deformed central part 4b separates from the holder 1, whereby this Shocks are cushioned elastically. As for the side shocks experienced by the shaft 3, they are caused by the Intrinsic elasticity of the massive part 4b of the bearing body 4 was added.
