Um eine Werkzeugmaschine mit einer Motorspindel, umfassend einen in eine Arbeitsspindel koaxial zur Spindelachse integrierten Hauptmotor, der seinerseits einen Rotor und einen Stator aufweist, und mit einer Kühlflächen des Hauptmotors gasförmiges Kühlmedium zu führenden Kühleinrichtung, derart zu verbessern, daß eine einfache und effektive Kühlung der Hauptmotoren der Motorspindeln möglich ist, wird vorgeschlagen, daß der Stator aus Statorblechen aufgebaut ist, welche ihrerseits Kühlflächen bilden und daß das gasförmige Kühlmedium unmittelbar längs der Kühlflächen der Statorbleche geführt ist.
摘要:
A multi-spindle lathe comprising a machine frame (12), a spindle drum (14), which is arranged in the machine frame (12), is rotatable about a spindle drum axis (16) and is made up at least partially of segments (80) cut out from flat material in a stacking direction (82) parallel to the spindle drum axis (16) and made to extend in stack planes (88) transversely in relation to the stacking direction (82), which segments have mutually overlapping receiving cutouts (90) and cooling channel cutouts (92, 96, 106), and so the spindle drum (14) has spindle motor receptacles (30) for spindle motors (32) and a cooling channel system (120, 130, 180) that is separated from said spindle motor receptacles by wall webs (98), characterized in that the cooling channel system has a number of subchannel systems (120, 130, 180), fed in parallel, for a liquid cooling medium.

Dispositif d'indexation et d'entrainement des broches d'un tour multibroches comprenant une pluralité de broches (21) montées au sein d'un tambour porte-broches rotatif, ledit dispositif comprenant un ensemble de pignons de broche (10), chacun desdits pignons de broche étant lié cinématiquement en rotation à une desdites broches, des moyens de rotation (4, 13, 14) destinés à faire tourner ledit tambour porte-broches de manière à faire passer les broches d'une station de travail à une autre, une pluralité de moteurs électriques (2) comprenant chacun un pignon de sortie (5) lié cinématiquement en rotation à un pignon de broche (10) au moyen d'un ensemble de pignons intermédiaires (7), des moyens d'indexation destinés à indexer les pignons de broche en face desdits pignons intermédiaires, une plaque d'appui fixe (3) et tel que les moyens d'indexation comprennent une roue (8) dentée intérieurement, fixée sur ladite plaque d'appui et à l'intérieur de laquelle les pignons de broche (10) roulent lorsque les broches passent d'une station de travail à une autre station de travail, ladite roue dentée comportant une pluralité d'espaces libres (9) aptes à recevoir chacun un dit pignon de broche lorsque lesdits pignons de broches (10) sont en prise avec lesdits pignons intermédiaires (7).
摘要:
The invention relates to an easy-to-produce housing for machine tool drives which is subject to none of the restrictions which are associated with the provision of a recess. According to the invention, the housing consists of a plurality of segments which are stacked in a specific stacking direction, cut out of a flat material and which extend on stacking planes perpendicular to the direction of stacking, each segment comprising material web systems which are associated therewith and have a constant thickness, extending in such a way that successive segments in the direction of stacking are disposed adjacent to each other with the material web system thereof, forming overlapping surfaces and are connected to each other in the region of the overlapping surfaces thereof in a flat material fit.
