Abstract
The invention aims to provide a special gearbox steering clutch for a crawler self-propelled rotary cultivator. The special gearbox steering clutch is simpler in structure, low in manufacturing and use cost, and convenient in assembly and maintenance and is applied to a special gearbox for the crawler self-propelled rotary cultivator. The special gearbox steering clutch for the crawler self-propelled rotary cultivator has the benefits that as the special gearbox steering clutch for the rotary cultivator adopts six equal steering jaws, the diameter of each steering jaw is increased, and each steering jaw is also heightened; the jaw working surface and the end surface adopt an inclined angle of 87 degrees, and the pressure of a steering spring is increased, thereby the working loads of the steering jaws are doubly reduced, and the automatic separating force when the steering jaws work is reduced; after improvement, the fault rate of the gearbox is greatly reduced, and the maintenance expense is reduced.
Description
Technical field
The invention belongs to agricultural machinery, specifically a kind of caterpillar band self-propelled rotovator special gear box steering cluth.
Background technology
Due to the destruction of wheel tractor when paddy-field-working to tillage pan, namely the caterpillar band self-propelled rotovator of the ecological agriculture arises at the historic moment, so far existing history more than 5 years.At present, the caterpillar band self-propelled rotovator special gear box of China does not also have appropriate products, be mostly the transformation of the way of self-propelled combine special gear box to form, because caterpillar band self-propelled rotovator special gear box is much larger compared with self-propelled combine special gear box live load, particularly self-propelled combine special gear box adopts 4 grades to divide 4 to turn to dental inlay, turn to dental inlay diameter little, it is extremely unreliable that self-propelled rotary cultivator special gear box uses, and fault is many.The improvement of this caterpillar band self-propelled rotovator special gear box steering cluth, at home and abroad have not been reported at present.
?
Summary of the invention
The object of the present invention is to provide a kind of structure simpler, manufacture, use cost is low, assembling and maintenance more easily caterpillar band self-propelled rotovator special gear box steering cluth are applied to caterpillar band self-propelled rotovator special gear box.
For solving the problems of the technologies described above, the invention provides following technical scheme:
A kind of caterpillar band self-propelled rotovator special gear box steering cluth, it is characterized in that it comprises gearbox body, braking in a turn axle is provided with in gearbox body, the middle part of braking in a turn axle is provided with central driver gear, the both sides of central driver gear are respectively arranged with tooth sector, central driver gear and tooth sector are respectively arranged with the dental inlay for turning to, and described dental inlay has 6 respectively, are 6 etc. divide setting at central driver gear and tooth sector.
Described one caterpillar band self-propelled rotovator special gear box steering cluth, is characterized in that described dental inlay working face and end face are 87 ° of oblique angles.
Described one caterpillar band self-propelled rotovator special gear box steering cluth, is characterized in that the vacant angle of described dental inlay is 10 °.
Described one caterpillar band self-propelled rotovator special gear box steering cluth, is characterized in that the external diameter of described dental inlay is 78mm, and the height of described dental inlay is 7mm.
One of the present invention caterpillar band self-propelled rotovator special gear box steering cluth, 6 are divided to turn to dental inlay because rotovator special gear box steering cluth have employed 6 grades, increase the diameter turning to dental inlay, also increase and turned to dental inlay, dental inlay working face and end face adopt 87 ° of oblique angles, and increase and turn to spring pressure, thus reduce at double and turn to dental inlay live load, decrease and turn to dental inlay automatic separating force operationally.After improving, greatly reduce Gearbox Fault rate, decrease maintenance cost.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, the present invention is the improvement based on former self-propelled combine special gear box steering cluth, its gearbox body 8 structure remains unchanged, the left and right sides is provided with braking in a turn bearing block 1, bearing 7, brake 2, turn to spring 6, tooth sector 3, intermediate arrangement central driver gear 4, power by gearbox through input idler gear (not shown in FIG.) transmission central driver gear 4; The dental inlay for turning to is had between central driver gear 4 and both sides tooth sector 3, by turning to shift fork (not shown in FIG.), can to be separated or in conjunction with dental inlay, namely cut off or connect the driving force from central driver gear, be rotated further and turn to shift fork, the outside mobile urges brake device 2 of tooth sector, makes tooth sector 3 brake, the reduction gearing that tooth sector often engages with reduction gearing (not shown in FIG.) is braked, and by travelling gear transmission, unit is braked; Unclamp and turn to declutch control lever, tooth sector, under the pushing effect turning to spring, makes to turn to dental inlay to recombine, unit straight-line travelling.Braking in a turn axle 5 is left and right all has a bearing to be bearing on braking in a turn bearing block 1, and the left and right symmetry of two braking in a turn bearing blocks 1 is bolted on gearbox body 8.Left and rightly turn to shift fork by rotating, supporting facility just can realize left and right having turned to easily and flexibly.Tooth sector dental inlay structure is shown in Fig. 2, central driver gear dental inlay structure is shown in Fig. 3; Being known by Fig. 2, Fig. 3 turns to the bossing angle of dental inlay to be β, and negative area angle is α, alpha-beta=vacant angle.
Central driver gear and tooth sector dental inlay change 6 into by 4, comparatively conventional types adds two, but 4 dental inlays in vacant angle and traditional facility are identical, dental inlay working face and end face adopt 87 ° of oblique angles (see Fig. 2, Fig. 3), dental inlay diameter increases, also increase and turned to dental inlay, remained the meshing characteristic that tradition 4 turns to dental inlay.Spring pressure is turned to strengthen.Braking in a turn bearing block improves sees Fig. 1.By above-mentioned improvement, turn to dental inlay unit are live load to reduce, stopped to turn to the automatic slip phenomenon of dental inlay, transmission efficiency is improved.After braking in a turn bearing block improves, metalworking technology difficulty is little, and machining accuracy easily ensures, also eliminates braking in a turn bearing cap.In a word, make assembling after improvement and keep in repair more convenient; Reduce manufacturing cost; Reduce fault rate, decrease maintenance cost, improve the overall performance of gearbox.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., be all included within protection scope of the present invention.
