Summary of the invention
The purpose of the present invention is aiming at disadvantages mentioned above, it is provided that three axle corn threshing machine gearboxes of the corn threshing machine gearbox lateral adjustments gear that a kind of cost is low, simple to operate.
The technical scheme is that and be achieved in that: three axle corn threshing machine gearboxes of lateral adjustments gear, including housing, it is characterized in that: three axles be arrangeding in parallel are installed in housing, it is the first axle respectively, second axle, 3rd axle, first axle and the 3rd axle are power shaft and output shaft respectively, the surface of the first axle has the chute paralleled to the axis, chute is installed a gear assembly, described gear assembly has three gears, it is the first gear from left to right respectively, second gear, 3rd gear, first gear, second gear, the number of teeth of the 3rd gear reduces successively;
Second axle is installed three gears from left to right, is the 4th gear, the 5th gear, the 6th gear respectively, the 4th gear, the 5th gear, the 6th gear the number of teeth increase successively;
3rd axle is installed the 7th gear, the 7th gear and the engagement of the 4th gear;
Being also equipped with action bars on housing, action bars has shift fork, described gear assembly has the position having jurisdiction over shift fork, and shift fork is had jurisdiction in this position;
Moving shift fork, gear assembly is at the first station, and gear assembly only has the 4th gear engagement on the first gear and the second axle;
Moving to the right shift fork, gear assembly does not have meshed gears at the second station, the first axle and the second axle;
Continuing to move to the right shift fork, gear assembly is at the 3rd station, and gear assembly only has the 5th gear engagement on the second gear and the second axle;
Moving to the right shift fork again, gear assembly is at the 4th station, and gear assembly only has the 6th gear engagement on the 3rd gear and the second axle.
The invention has the beneficial effects as follows: such corn threshing machine gearbox-there is the advantage that cost is low, simple to operate.
Accompanying drawing explanation
Fig. 1 is the gear assembly structural representation in the first station present invention.
Fig. 2 is the gear assembly structural representation in the second station present invention.
Fig. 3 is the gear assembly structural representation in the 3rd station present invention.
Fig. 4 is the gear assembly structural representation in the 4th station present invention.
Wherein: 1, housing the 2, first axle the 3, second axle the 4, the 3rd axle 5, gear assembly the 6, first gear the 7, second gear the 8, the 3rd gear the 9, the 4th gear the 10, the 5th gear the 11, the 6th gear the 12, the 7th gear 13, action bars 14, shift fork.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Such as Fig. 1, 2, 3, shown in 4, three axle corn threshing machine gearboxes of lateral adjustments gear, including housing 1, it is characterized in that: three axles be arrangeding in parallel are installed in housing, it is the first axle 2 respectively, second axle 3, 3rd axle 4, first axle and the 3rd axle are power shaft and output shaft respectively, the surface of the first axle has the chute paralleled to the axis, chute is installed a gear assembly 5, described gear assembly has three gears, it is the first gear 6 from left to right respectively, second gear 7, 3rd gear 8, first gear, second gear, the number of teeth of the 3rd gear reduces successively;
On the second axle 3 from left to right install three gears, be the 4th gear the 9, the 5th gear the 10, the 6th gear 11 respectively, the 4th gear, the 5th gear, the 6th gear the number of teeth increase successively;
3rd axle is installed the 7th gear 12, the 7th gear and the engagement of the 4th gear;
Being also equipped with action bars 13 on housing, action bars has shift fork 14, described gear assembly has the position having jurisdiction over shift fork, and shift fork is had jurisdiction in this position;
Moving shift fork, gear assembly is at the first station, and gear assembly only has the 4th gear engagement on the first gear and the second axle;As it is shown in figure 1, so, change speed gear box is with relatively low speed output;
Moving to the right shift fork, gear assembly does not have meshed gears at the second station, the first axle and the second axle;As in figure 2 it is shown, so, change speed gear box exports with the speed of zero;
Continuing to move to the right shift fork, gear assembly is at the 3rd station, and gear assembly only has the 5th gear engagement on the second gear and the second axle;As it is shown on figure 3, so, change speed gear box exports with middling speed;
Moving to the right shift fork again, gear assembly is at the 4th station, and gear assembly only has the 6th gear engagement on the 3rd gear and the second axle, and as shown in Figure 4, so, change speed gear box is with speedy carding process.
I.e. action bars lateral adjustments, has advantages of the present invention.
The foregoing is only specific embodiments of the invention, but the architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and change or the modification made all are encompassed in the scope of the claims of the present invention.
