To this end, the spindle (1) has a connecting plate (100) for connecting the spindle (1) to a compressed air unit and a lubricant supply of a machine tool, a shank element (110) that can be displaced in the longitudinal direction (L) of the spindle (1) and is mounted in the connecting plate (100) of the spindle (1), as well as a spindle shank (121) that can be rotated in the circumferential direction (U) of the spindle (1), with a connecting piece (124) for connecting a connecting element (202) of a collet chuck (200) set up to receive a processing tool or a maintenance tool (300) to the spindle.

Abstract: The aim of the invention is to provide an electrochemical cell which can be produced as simply as possible and with which fluid can flow out of the interior in the event of an overpressure in the interior of the electrochemical cell. This is achieved by an electrochemical cell that comprises a housing, which surrounds the interior of the electrochemical cell, and a rupture device, which is arranged on a wall of the housing and is in particular formed integrally with the wall, wherein the rupture device comprises at least one rupture web, wherein the at least one rupture web has a thickness varying in the longitudinal direction, and/or wherein the at least one rupture web is formed by at least one first depression, which is arranged on an inner side, facing the interior, of the wall, and by at least one second depression, which is arranged on an outer side, facing away from the interior, of the wall.

Abstract: In order to provide a rupture device which can be produced as simply as possible and which enables a controlled opening of a container in the event of an overpressure, it is proposed that the rupture device comprise a wall component which has at least one rupture web, wherein the at least one rupture web has a thickness varying in the longitudinal direction, and/or wherein the at least one rupture web is formed by at least one first depression, which is arranged on a first side of the wall component, and at least one second depression, which is arranged on a second side, facing away from the first side, of the wall component.

Abstract: The aim of the invention is to provide an electrochemical cell that can be produced as simply as possible and has a long service life. This is achieved in that the electrochemical cell comprises a first contact element that connects a first cell terminal to a first connection conductor and that is fixed to a cover element of the electrochemical cell by means of a first potting element in a first connection region, said first potting element being made of a first polymer material that comprises or is made of a first resin material, and/or the electrochemical cell comprises a second contact element that connects a second cell terminal to a second connection conductor and that is fixed to the cover element by means of a second potting element in a second connection region, said second potting element being made of a second polymer material that comprises or is made of a second resin material.

Abstract: The invention relates to an electrical machine (1) comprising a rotor (4) which is rotatably mounted around a rotation axis (5) extending in the axial direction (3) in bearing devices (16, 17), a stator (7) having two axial ends, an air gap between rotor and stator, an interior chamber (10) encompassing the stator (7) and rotor (4), a sleeve (11) encompassing a first part (111) which encloses the interior chamber (10), a frame (12) having a first (123) and a second (121) longitudinal support (123), a first (122) and a second (124) cross-support, and a dividing device (2) on the frame (12). The stator (7) comprises a fastening device (15) for connection to the frame (12) and the dividing device (2) can make the interior chamber accessible from the outside in a plane parallel to the frame (12). The invention further relates to a collection, to a frame (12), to a sleeve (11), or to a service or production method of such an electrical machine (1).
