Description

Vor allem bei kleinen elektrischen Maschinen kommen mit Vorteil kalottenförmige Gleitlager zur Anwendung, da diese infolge ihrer Selbsteinstellung in Achsrichtung, auch bei nicht ganz eindeutiger, axialer Ausrichtung der Bohrungen, eine einwandfreie Lagerung der Wellen ermöglichen. Die Lagerkalotten werden dabei mit ihren Außenenden gegen den Lagerdeckel oder gegen einen Lagereinsatzkörper abgestützt, während sie am Innenende durch eine federnde Halterung gehalten werden, welche die Selbsteinstellung der Lagerkalotten nicht behindert, im übrigen aber eine Abstützung in axialer Richtung bildet. Die federnde Halterung ist bei manchen Ausführungsformen hinsichtlich ihrer Federkraft durch Gewinderinge einstellbar.Dome-shaped ones are particularly advantageous for small electrical machines Plain bearings are used because they are self-adjusting in the axial direction, even if the axial alignment of the bores is not entirely clear, a perfect one Enable storage of the shafts. The bearing domes are thereby with their outer ends supported against the bearing cap or against a bearing insert body while they at the inner end are held by a resilient bracket, which allows the self-adjustment the bearing cap is not hindered, but otherwise a support in the axial direction forms. The resilient holder is in some embodiments with regard to their Spring force adjustable by means of threaded rings.

Die Erfindung bezieht sich auf eine Vorrichtung zur federnden Halterung eines Kalottenlagers nach obiger Art. Sie besteht im wesentlichen darin, daß das die Lagerkalotte am Innenende derselben axial abstützende Halteglied seinerseits durch eine verstellbare und feststellbare Haltefeder abgestützt ist.The invention relates to a device for resilient mounting a spherical bearing according to the above type. It consists essentially in the fact that the the bearing cap at the inner end of the same axially supporting retaining member in turn is supported by an adjustable and lockable retaining spring.

Bei der erfindungsgemäßen Ausführung wird das Halteglied nicht als Feder ausgeführt, sondern vorzugsweise als kugliges Halteblech. Die Federkraft wird von einer zusätzlichen Haltefeder aufgebracht. Diese Haltefeder besitzt Lappen, welche vorzugsweise ausgestanzt sind. Die Lappen greifen in einen Bajonettverschluß am Lagerkörper ein, welcher in üblicher Weise mit schräg verlaufenden Schlitzen versehen ist, wobei diese Schlitze Rasten besitzen, durch welche die Feder in jeder Lage einwandfrei festgehalten wird. Die Feinheit der Einstellung ist unbegrenzt und kann durch die Schräge der Schlitze verändert werden. Die Einstellung selbst erfolgt durch Verdrehen der Haltefeder.In the embodiment of the invention, the holding member is not as Spring executed, but preferably as a spherical retaining plate. The spring force will applied by an additional retaining spring. This retaining spring has tabs which are preferably punched out. The tabs engage in a bayonet lock on the bearing body, which in the usual way with inclined slots is provided, these slots having detents through which the spring in each Location is flawlessly recorded. The fineness of the setting is unlimited and can be changed by the incline of the slots. The setting itself takes place by turning the retaining spring.

Der Vorteil gegenüber den bekannten Ausführungen liegt in der Ersparnis von zwei Gewinden, deren Herstellung sehr teuer ist. Der Bajonettverschluß mit seinen Rasten kann dagegen in einem Arbeitsgang gespritzt oder gepreßt werden. Ebenso ist die Herstellung der Feder mit mehreren Lappen ein einfacher Arbeitsvorgang. Weiterhin ist die Federkraft durch die Rasten feststellbar und kann sich von selbst nicht ändern.The advantage over the known designs is the savings of two threads, which are very expensive to manufacture. The bayonet lock with his Latches, on the other hand, can be injected or pressed in one operation. Likewise is making the nib with multiple lobes is a simple operation. Farther the spring force can be determined by the notches and cannot by itself change.

Die Zeichnung zeigt ein erfindungsgemäß ausgeführtes Beispiel. In Fig. i ist die Rückansicht und in Fig. 2 ein Längsschnitt eines Kalottenlagers dargestellt.The drawing shows an example carried out according to the invention. In FIG. 1 shows the rear view and FIG. 2 shows a longitudinal section of a spherical bearing.

Die Welle Io lagert in der Kalotte i i. Diese ruht einerseits in dem Lagerkörper I2, andererseits in dem kugligen Halteblech 13. Auf das Halteblech 13 wirkt die Haltefeder 14, deren Lappen in dem mit Rasten versehenen Bajonettverschluß 15 liegen. 16 und 17 sind Spritzscheiben, welche zusammen mit dem Schmierfilz 18 eine Ölumlaufschmierung bewirken. i9 ist das eigentliche Lagerschild.The shaft Io is stored in the dome i i. This rests on the one hand in the bearing body I2, on the other hand in the spherical retaining plate 13. The retaining spring 14 acts on the retaining plate 13, the tabs of which lie in the bayonet catch 15 provided with notches. 16 and 17 are splash disks which, together with the lubricating felt 18, effect circulating oil lubrication. i9 is the actual end shield.
