Abstract
A tool head includes a working slide which can be adjusted relative to a basic body, and an electric adjusting motor which acts on the working slide via gears. The motor includes a stator and a rotor which runs round in the stator, bears an output shaft and is mounted in two pivot bearings arranged at a distance from one another, wherein one of the pivot bearings is arranged with an outer ring in a basic body-mounted stator housing and with an inner ring directly or indirectly on the output shaft.
Claims9
A tool head for use in machine tools comprising a base body, at least one working slide which can be adjusted in relation to the base body and an adjustment motor arranged in the base body and acting on the working slide via a transmission member, wherein the adjustment motor has a stator arranged in the base body and a rotor which rotates in the stator, is fitted with an output shaft and is mounted in two rotary bearings which are arranged at a distance from one another, one of the rotary bearings is arranged with an outer ring in a stator housing which is fixed to the base body and with an inner ring directly or indirectly on the output shaft, and the stator housing has a sleeve part which partially engages over the stator axially on the outside and is fixedly connected to the stator in terms of rotation and displacement, and a bearing cover which closes off the sleeve part on a gear side and is fitted with the outer ring of a first rotary bearing.
