Abstract

The invention discloses a support for a large machine tool transmission gear box and relates to the technical field of mechanical equipment manufacture. The support comprises a box body which is provided with two cavities. Two openings communicated with the two cavities respectively are opened on one end face of the box body, and two other openings communicated with the two cavities respectively are opened on the side faces of the box body; and reinforcing ribs are arranged on the outsides of the box body. By means of the support, the problems that the reverse backlash accuracy of two motors and the accuracy of the whole machine tool are reduced caused by the displacement between two gear boxes due to the insufficient rigidity of the transmission gear box support can be solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a bracket for supporting a transmission gearbox of a large machine tool. Background technique [0002] Rack and pinion transmission is a transmission form mainly selected by large machine tools. Rack and pinion transmission has the advantages of simple structure, easy installation and adjustment, etc., but there will be backlash when using its transmission, which will affect the machining accuracy of the machine tool; For clearance, mechanical anti-backlash or dual-motor anti-backlash structure is usually used. The double-motor anti-backlash structure has large transmission power, reliable anti-backlash, and stable precision, so it is widely used. However, the dual-motor anti-backlash structure in the prior art is composed of two sets of independent gear reduction boxes, and the two sets of independent gear reduction boxes are supported by independent g...
