Abstract
The invention relates to a two-point support device of a combined driving input gear, and belongs to the technical field of a driving device of a plate bending machine, aiming at providing a two-point support device of a combined driving input gear. The two-point support device has the advantages that the working condition of a speed reducer is improved, the service life of the speed reducer is prolonged, the rigidity of a transmission case body is improved, the shaking of the machine during work is reduced, and the service life of each driving gear is prolonged. The two-point support device adopts the technical scheme that the case body is sheathed on a working roll of the plate bending machine by a bearing, a plurality of driving gears and driven gears are respectively arranged in the case body, the driven gears are fixedly connected with the working roll of the plate bending machine by splines, a plurality of gear shafts which have the same number with the driving gears penetrate and are installed on the two side walls of the case body by bearings, each driving gear is fixedly connected with the corresponding gear shaft by a spline, and all driving gears are respectively engaged with the driven gears. The two-point support device is mainly applied to the plate bending machine.
Description
Technical field
A kind of two point support device that collaborates to drive input gear of the present invention belongs to the plate bending rolls technical field of driving.
Background technique
At present to drive the structural type that plate bending rolls adopts be to drive respectively separately planetary reducer by a plurality of motors or motor at general interflow, on the output shaft of each planetary reducer, a small gear all is installed, by gearwheel of the common driving of a plurality of small gears moment of torsion is passed to top working roll.The shortcoming of this kind driving is: small gear belongs to cantilever and installs, roll in the process at steel plate, the axial force that produces and radial force are born by the output shaft of retarder, the force-bearing situation of retarder is bad, retarder impacts large when work, noise is large, and impact in working life of retarder is caused more greatly and easily becoming flexible of retarder and support body attachment screw, has more aggravated the generation of this kind harm; And because structural limitations, this moment, the output shaft of retarder was often long than standard retarder, again the transmission of gear was brought harm in stressed rear distortion, had a strong impact on the working life of gear.
Summary of the invention
A kind of two point support device that collaborates to drive input gear of the present invention, overcome the deficiency that prior art exists, a kind of retarder operating mode of improving is provided, prolonged deceleration device working life, strengthen the transmission case body rigidity, vibrations when reducing machine works, the interflow that prolongs driving gear working life drives the two point support device of input gear.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of two point support device that collaborates to drive input gear, comprise casing, driving gear, gear shaft, driven gear, retarder and motor, casing is contained on the plate bending rolls top working roll by bearing housing, a plurality of driving gears and driven gear all are positioned at box house, driven gear is fastened on the described plate bending rolls top working roll by key, the a plurality of gear shafts identical with described driving gear quantity all run through on two sidewalls that are installed in casing by bearing, each driving gear all is fastened on the corresponding gear shaft by key, and all driving gears all mesh with described driven gear;
The external part of each gear shaft all is connected with the output terminal of a retarder separately, and the input end of each retarder all is connected with a motor separately, and described retarder is fixed by screws on the described casing.
The external part of described gear shaft is connected with the Placement of the output terminal of retarder by interior external splines, is provided with external splines on the external part of gear shaft, is provided with internal spline on the output terminal of retarder.
A sidewall of described casing is to install by bolt is movable.
Described retarder is planetary reducer.
The beneficial effect that the present invention compared with prior art has is: among the present invention, the gear shaft that driving gear is installed adopts two point to support, like this in the roll bending process, the axial force that driving gear bears and radial force have passed on the casing, retarder only bears moment of torsion in the course of the work, so that the rigidity of whole drive part has strengthened the more reasonable stress of structure greatly, machine vibrations in the course of the work are little, noise is little, and the life-span of retarder and driving gear has prolonged greatly; Planetary reducer and gear shaft direct connection have improved assembling and the maintainability of planetary reducer.
