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
The present invention relates to plant equipment manufacturing technology field, especially a kind of support for supporting heavy duty machine tools uni-drive gear box.
Background technology
Rack pinion is a kind of type of belt drive that heavy duty machine tools are mainly selected, and it is simple that rack pinion has structure, the advantages such as easy mounting and adjusting, but adopts during its transmission and have backlass, affects the machining accuracy of lathe; Usually select machinery to disappear gap or double-motor anti-backlash structure when eliminating backlass, double-motor anti-backlash structure has that to transmit power large, and the gap that disappears is reliable, stable accuracy and being widely adopted.But the double-motor anti-backlash structure in prior art is employing two overlaps independently gear reduction box formation, two overlap independently gear reduction box adopts independently gear reduction box bracket to support respectively, usually exposing the shortcoming of gear reduction box bracket rigidity deficiency when transmitting larger power, thereby producing series of problems:
1, because gear reduction box bracket rigidity is not enough, the dystopy between two casings can be caused, cause the centre-to-centre spacing between the wheel and rack on gear-box to change, the wearing and tearing of gear and tooth bar are strengthened, has damaged the precision of driving-chain thus affected whole machine tool accuracy.
2, due to the dystopy between two casings, also can cause the improper engagement between driving cog wheel and rack, the transmission efficiency between wheel and rack is affected, and bi-motor reverse anti-backlash precision reduces, and also causes driving motor consumed power to strengthen simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of heavy duty machine tools travelling gear box bracket, it can solve because travelling gear box bracket rigidity is not enough, causes dystopy between two gear housings and causes the problem that bi-motor reverse anti-backlash precision and whole machine tool accuracy reduce.
In order to solve the problem, technical scheme of the present invention is: this heavy duty machine tools travelling gear box bracket, include casing, two cavitys are provided with in described casing, an end face of described casing offers respectively with two openings of described two cavity connects, the side opening of described casing be provided with two other respectively with the opening of described two cavity connects; Described casing arranged outside has reinforcement.
In technique scheme, more specifically scheme can also be: described casing is made up of Unitary ductile iron.
Further, described reinforcement is arranged in the corresponding position outside described casing between described two cavitys.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, the present invention can not cause the dystopy between two travelling gear box bodies when transmitting very large power, effectively maintain the positional precision had when unpowered input, thus make it that the centre-to-centre spacing between rack-and-pinion can not be made in transmission process to change, can effectively improve its transmission efficiency, make bi-motor reverse anti-backlash reach full accuracy, thus ensure and improve whole machine tool accuracy.
2, The present invention reduces the wearing and tearing of gear and tooth bar, improve the life-span of equipment, also reduce the consumption of driving motor electric energy simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Heavy duty machine tools travelling gear box bracket shown in Fig. 1, Fig. 2 and Fig. 3 includes casing 1, is provided with left and right two cavitys, i.e. left cavity 3 and right cavity 4 in casing 1; Left cavity 3 offers opening on the left of the end face of casing 1, and for installing the left side epicyclic gearbox 6 being connected with motor 5, left cavity 3 is provided with opening in left end one side of casing 1 bottom, engages with Left Drive tooth bar for allowing Left Drive gear 7; Right cavity 4 is provided with opening at the end face right side opening of casing 1, and for installing the right side epicyclic gearbox 9 being connected with motor 10, right cavity 4 is provided with opening in left end one side of casing 1 bottom, engages with right driving rack for allowing right travelling gear 8; As shown in Figure 4, Figure 5 and Figure 6.The arranged outside of the casing 1 between left cavity 3 and right cavity 4 has reinforcement 2, strengthens the intensity of whole casing 1; After whole casing 1 adopts Unitary ductile iron, machining is made.
