Description

Kurbellager für Fahrräder. Die Erfindung betrifft Fahrradkurbellager, die mit zwei Kugellagerungen ausgerüstet werden, von denen die eine rechts und die andere links vom Rahmengestell liegt. Das Neue besteht darin, daß zur genauen Einstellung des Lagers der eine Lagerteller des Zwillingskugellagers als Mutter ausgebildet ist, in welcher sich der andere Lagerteller im Gewinde führt.Crank bearings for bicycles. The invention relates to bicycle crank bearings, which are equipped with two ball bearings, one of which is on the right and the other the other is to the left of the frame. The new thing is that for precise adjustment of the bearing of a bearing plate of the twin ball bearing designed as a nut is in which the other bearing plate leads in the thread.

In der Zeichnung ist die Erfindung in, fünf Abbildungen dargestellt. Abb. z zeigt einen Schnitt durch das Tretkurbellager.In the drawing, the invention is shown in five figures. Fig. Z shows a section through the crank bearing.

Abb. a zeigt eine Ansicht eines Lagereinsatzes nach A-B, Abb.3 die Ansicht eines Zwischenrings, Abb. q. diejenige des inneren Lagertellers und Abb. g die Ansicht eines Verschlußrings. In der Tretkurbellagerhülse a sind zwei doppelte Kugellager paarweise angeordnet. Zu diesem Zwecke trägt die Tretkurbelachse b zwei Konen c und cl, die doppelseitig ausgebildet sind, so daß auf jeden Konus zwei Kugelkränze. d, dl bzw. e, e1 Platz finden. Zu den Kugelkränzen d und e gehören die äußeren Lagerteller f und g, zu den Kugelkränzen dl und e1 die inneren Lagerteller h und i. Diese inneren Lagerkränze sind in die ,äußeren f bzw. g, die einen mit Innengewinde versehenen Kragen k tragen, eingeschraubt und in der richtigen Einstellung für den Kugeldruck in bekannter Weise durchdie gegen Drehung gesicherte Zwischenscheibe l und den Verschlußring m festgeh legt; also jeder der Lagerteller f und g umschließt ein doppeltes Kugellager und ist gegen die Achse durch die Einstellung zu seinem Konus festgelegt. Die äußeren Flächen der Teile 1 und g sind glatt zylindrisch, so daß das fertig eingestellte Tretkurbellager in die Lagerbuchse a eingeschoben und durch die Schraubenbolzen a festgestellt werden kann. Die Ölung des Lagers geschieht durch die Öffnungen, die durch Schraubenbolzen a geschlossen werden. Selbstverständlich muß mindestens eine der Tretkurbeln beim Ausbau des Lagers abgenommen werden.Fig. A shows a view of a bearing insert according to AB, Fig. 3 shows a view of an intermediate ring, Fig. Q. that of the inner bearing plate and Fig. g the view of a locking ring. Two double ball bearings are arranged in pairs in the pedal crank bearing sleeve a. For this purpose, the crank axle b has two cones c and cl, which are designed on both sides, so that two ball races on each cone. d, dl or e, e1 find space. The outer bearing plates f and g belong to the ball races d and e, the inner bearing plates h and i belong to the ball races dl and e1. These inner bearing rims are screwed into the outer f and g, which carry an internally threaded collar k, and fixed in the correct setting for the ball pressure in a known manner by the intermediate disk l secured against rotation and the locking ring m; so each of the bearing plates f and g encloses a double ball bearing and is fixed against the axis by the setting to its cone. The outer surfaces of the parts 1 and g are smoothly cylindrical, so that the fully adjusted pedal crank bearing can be pushed into the bearing bushing a and fixed by the screw bolts a. The bearing is lubricated through the openings which are closed by screw bolts a. Of course, at least one of the cranks must be removed when removing the bearing.
