Abstract

Proposed is a two-stage machine tool gearing, in particular spindle gearing, comprising a planetary gear set (16), in which the spindle (7) or a spindle insert can be connected in a form-fitting or force-fitting manner to the drive output (2, 3) of the gearing (17), which gearing (17) has a first drive output shaft (2) and a second drive output shaft (3), wherein the first drive output shaft (2) is rotationally fixedly connected to the drive input shaft (1) and can be detachably connected by means of a first switching element (5) to the sun gear (4) of the planetary gear set (17), wherein the second drive output shaft (3) is rotationally fixedly connected to the web (19) of the planetary gear set (17) and the ring gear (8) of the planetary gear set (17) is rotationally fixedly connected to the housing (18) of the gearing, and wherein a second switching element (6) is provided which produces a detachable connection between the spindle (7) or a spindle insert and, selectively, the first or the second drive output shaft (2) or (3).

Description

technical field [0001] The invention relates to a two-stage machine tool drive according to the preamble of claim 1, in particular for tool feeders at high torques and high rotational speeds. Background technique [0002] Machine tool drives, in particular tool boxes, are well known in the prior art and generally include planetary gear sets as well as switching devices for switching the desired gear stages. [0003] For example, in the applicant's DE 10 2004 003 684 A1, a machine tool transmission, especially a tool box, is disclosed, wherein the transmission of force or torque from the driven shaft to the main shaft of the transmission is carried out directly, and the main shaft is relative to the The driven shaft is arranged coaxially. [0004] In addition, DE 10 2004 003 685 A1 of the applicant also discloses a machine tool transmission mechanism, especially a tool box, wherein the transmission of force or moment from the driven shaft of the transmission mechanism to the...
