Offenbart sind ein Verfahren und eine Einrichtung zum Einbringen einer Lagerbuchse (8) in ein Lagerauge (6) sowie eine Werkstück, das nach einem derartigen Verfahren oder mit einer derartigen Einrichtung hergestellt ist. Erfindungsgemäß wird die Lagerbuchse (8) in das Lagerauge (6) eingewalzt.

Herramienta, maquina y metodo para calibrar bujes.

Se describe una herramienta de calibración para calibrar un buje (10). Tiene una barra (1; 101; 201), que comprende un primer segmento de calibración redondeado (2a; 102a) y al menos un segmento de calibración redondeado adicional (2b; 102b), ambos que se extienden radialmente con respecto a la barra. Para formación exacta de una superficie interior cilíndrica del buje, la barra con los segmentos de calibración puede moverse linealmente a través del buje. En este caso, una distancia (d1; D1) entre los dos segmentos de calibración se establece para ser lo suficientemente pequeña para que el primer segmento de calibración pueda llevarse en contacto con una región de círculo completo (13) del buje que está cerrada a lo largo de la circunferencia del buje, mientras al mismo tiempo el segmento de calibración adicional puede llevarse en contacto con una región de círculo parcial (14a) del buje que está parcialmente abierta a lo largo de la circunferencia del buje. También se describen dos variantes de un método para calibrar un buje, que tiene una región de círculo completo cerrada y una o dos regiones de círculo parcial (14a, 14b) parcialmente abiertas. El método utiliza una herramienta de calibración que tiene una barra que comprende un primer segmento de calibración redondeado y que comprende al menos un segundo segmento de calibración redondeado. En este caso, los segmentos de calibración se extienden radialmente con respecto a la barra. Los segmentos de calibración se introducen en las regiones del buje y con ello se soportan mutuamente.

ferramenta, máquina e processo para a calibração de buchas

resumo patente de invenção: "ferramenta, máquina e processo para a calibração de buchas". a presente invenção refere-se a uma ferramenta de calibração para a calibração de uma bucha (10). ela possui uma barra (1; 101; 201) que apresenta um primeiro segmento de calibração (2a; 102a) arredondado e pelo menos mais um outro segmento de calibração (2b; 102b), ambos radialmente ampliados em relação à barra. para uma configuração exata de uma superfície interna cilíndrica da bucha, a barra com os segmentos de calibração pode ser movida linearmente através da bucha. nisso, uma distância (d1; d1) entre os dois segmentos de calibração é tão curta que o primeiro segmento de calibração pode ser colocado em contato com uma região do círculo inteiro (13) fechado ao longo da circunferência da bucha (10), ao passo que ao mesmo tempo o outro segmento de calibração pode ser colocado em contato com uma primeira região de círculo parcial (14a) parcialmente aberto ao longo da circunferência da bucha. também são revelados duas variações de um processo para a calibração de uma bucha que apresenta uma região do círculo inteiro fechada e uma ou duas regiões de círculo parcial, parcialmente abertas (14a, 14b). o processo utiliza uma ferramenta de calibração que possui uma barra com um primeiro segmento de calibração arredondado e com pelo menos um segundo segmento de calibração arredondado. no caso, os segmentos de calibração são radialmente ampliados em comparação com a barra. os segmentos de calibração são introduzidos nas regiões da bucha, apoiando-se um no outro.

Werkzeug, maschine und verfahren zum kalibrieren von buchsen

Offenbart ist eine Kalibrierwerkzeug zum Kalibrieren einer Buchse (10). Es hat eine Stange (1; 101; 201), die ein erstes verrundetes Kalibriersegment (2a; 102a) und zumindest ein weiteres verrundetes Kalibriersegment (2b; 102b) aufweist, die beide gegenüber der Stange radial erweitert sind. Zur genauen Formgebung einer zylindrischen Innenfläche der Buchse ist die Stange mit den Kalibriersegmenten durch die Buchse linear bewegbar. Dabei ist ein Abstand (d1; D1) zwischen den beiden Kalibriersegmenten derart kurz bemessen, dass das erste Kalibriersegment mit einem entlang dem Umfang der Buchse geschlossenen Vollkreisbereich (13) der Buchse in Anlage gebracht werden kann, während gleichzeitig das weitere Kalibriersegment mit einem entlang dem Umfang der Buchse teilweise offen Teilkreisbereich (14a) der Buchse in Anlage gebracht werden kann. Offenbart sind weiterhin zwei Varianten eines Verfahrens zum Kalibrieren einer Buchse, die einen geschlossenen Vollkreisbereich und einen oder zwei teilweise offene Teilkreisbereiche (14a, 14b) hat. Das Verfahren nutzt ein Kalibrierwerkzeug, das einer Stange mit einem ersten verrundeten Kalibriersegment und mit zumindest einem zweiten verrundeten Kalibriersegment hat. Dabei sind die Kalibriersegmente gegenüber der Stange radial erweitert. Die Kalibriersegmente werden in die Bereiche der Buchse eingeführt und stützen sich dabei gegenseitig.

Device and method for fracture-separating workpieces

Rolling tool

Disclosed is a rolling tool which serves for working—in particular rolling smooth—an inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. The at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. The fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication.
