Abstract

Re-adjustable and adjustable, self-centring and self-locking internal bottom bracket ball bearing unit, especially for use in vehicles with two or more wheels whose drives are muscular force and/or auxiliary motors. Previously used complete internal bottom bracket ball bearings are based on the use of deep groove ball bearings or their systems and therefore require axles - and of course ball bearings or ball bearing races - specially manufactured for them. The construction principle does not permit re-adjustment when required. In the internal bottom bracket ball bearing unit presented, both a previously used bottom bracket ball bearing axle and commercially available ball bearing races are used. By means of an adjustment ring with a thread which can only be used in one direction, the bearing play can be adjusted and re-adjusted as required and is at the same time also secured against loosening. By virtue of overlapping diameters of the bottom bracket ball bearing unit and of the installation housing, and by virtue of the slip phases provided, centring and form fitting matched to the housing occurs during assembly so that the bottom bracket ball bearing unit is both attached centrally and secured against rotation. By maintaining a smaller diameter in the central area of the internal bottom bracket ball bearing unit, space is provided which permits cables to be led through the housing of the bottom bracket ball bearing.

Description

Beschreibungdescription

ein- und nachstellbare, selbstzentrierende und selbsthemmende Innentretlagereinheit zur vornehmlichen Verwendung bei Zwei- und Mehr-Rädern, deren Antriebe Muskelkraft und / oder Hilfsmotoren sind.adjustable, self-centering and self-locking inner bottom bracket unit For the main use with two- and multi-wheelers whose drives are muscle power and / or auxiliary engines.

Die Erfindung bezieht sich auf die Verwendung einer vormontierten Einheit (x) in Verbindung mit einer Feststellmutter (6).The invention relates to the use of a pre-assembled Unit (x) in connection with a locking nut (6).

Die vormontierte Einheit (x) besteht aus einer Trägerhülse (1), einer Tretlagerwelle (2), 2 Lagerschalen (3), 2 Kugellagerringen (4) und einem Nachstellring (5).The pre-assembled unit (x) consists of a carrier sleeve (1), a Bottom bracket shaft (2), 2 bearing shells (3), 2 ball bearing rings (4) and an adjusting ring (5).

Durch eine jeweils unterschiedliche Auslegung der äusseren Dimensionen ist das Innentretlager (x) in dieser Bauart in allen bisher herkömmlichen Tretlagergehäusen (7) einsetzbar.Due to a different interpretation of the outer dimensions is the inner bottom bracket (x) in this design in all conventional bottom bracket housings (7) can be used.

Die Montage erfolgt durch Einführen der vormontierten Einheit (x) in das Tretlagergehäuse (7) einerseits und dem Aufschrauben und Festziehen der Feststellmutter (6) andererseits.The assembly is carried out by inserting the pre-assembled unit (x) into the bottom bracket shell (7) on the one hand and screwing on and tightening the locking nut (6) on the other hand.

Die Besonderheit der Erfindung liegt darin, daß: 1. durch die Schlumpfphasen (A) + (B) an der Trägerhülse (1) und der Feststellmutter (6) eine Selbstzentrierung erfolgt, 2. durch das Verschrauben der Feststellmutter (6) mit der vormontierten Innentretlagereinheit (x) diese Innentretlagereinheit (x) in das Tretlagergehäuse (7) gezogen wird.The special feature of the invention is that: 1. Through the Smurf phases (A) + (B) self-centering on the support sleeve (1) and the locking nut (6) takes place, 2. by screwing the locking nut (6) to the pre-assembled one Inner pedal bearing unit (x) insert this inner pedal bearing unit (x) into the bottom bracket housing (7) is pulled.

Die beiden sich dabei überdeckenden Durchmesser (Außendurchmesser (c) der Innentretlagereinheit (x) / Innendurchmesser (C1) des Tretlagergehäuses (7) ergeben einen Preßsitz und sind somit gegen Verdrehung gesichert. The two overlapping diameters (outer diameter (c) the inner bottom bracket unit (x) / inner diameter (C1) of the bottom bracket shell (7) result in a press fit and are thus secured against rotation.

3. durch Beibehaltung eines geringeren Durchmessers von der Gewindeseite her bis hin zum Beginn der Schlumpfphase (A) an der vormontierten Innentretlagereinheit (X) ein Raum geschaffen ist, durch welchen Kabel (8) durch das Tretlagergehäuse (7) geführt werden können.3. by maintaining a smaller diameter on the thread side up to the beginning of the smurf phase (A) on the pre-assembled inner bottom bracket unit (X) a space is created through which cable (8) through the bottom bracket shell (7) can be performed.

Auch bei nachträglicher Montage der vormontierten Tretlagereinheit (x) werden vorhandene Kabel (8) nicht beschädigt oder zerstört. Even if the pre-assembled bottom bracket unit is retrofitted (x) existing cables (8) are not damaged or destroyed.

4. durch Verwendung eines Nachstellringes (5), der mit einem nur in einer Richtung benutzbaren Gewinde versehen ist, das Lagerspiel ein- und nachstellbar aber gegen Lösen gesichert ist.4. by using an adjusting ring (5), which is only in one direction usable thread is provided, the bearing play can be adjusted and readjusted but is secured against loosening.

5. durch Verwendung der dargestellten Konstruktion bisher im Handel verwendete Tretlagerachsen und Kugelringe verwendet werden können.5. by using the construction shown so far in the trade used bottom bracket axles and ball rings can be used.
