Abstract
The utility model relates to a gear box steering mechanism of a crawler type harvester, comprising a braking shaft, a main drive gear with clutch teeth, a steering gear, a steering shifting fork, a return spring and a friction piece, wherein the main drive gear and the steering gear are connected with meshed teeth in a clutch way, the main drive gear is vertically assembled on the whole braking shaft, the steering shifting fork is installed in a shifting fork slot of the steering gear, the return spring is arranged between the braking shaft and the steering gear, the friction piece is sheathed on the steering gear, an inclined angle of 88 degrees is formed at a part where the main drive gear is combined with the clutch teeth of the steering gear, and the clutch teeth of the main drive gear has a digging angle of 30 degrees. The gear box steering mechanism of the crawler type harvester has the advantages that the structure is novel, the rigidity of the braking shaft is high, the clutching property is good, and the service life is long.
Description
Technical field
The utility model relates to crawler type grain header gearbox steering mechanism, especially adopts the crawler type grain header gearbox steering mechanism of jaw clutch formula structure.
Background technology
The steering mechanism of crawler type grain header gearbox mainly adopts jaw clutch formula, differential type and steering cluth formula several at present.Adopt the form of jaw clutch mostly in the steering mechanism of the crawler type grain header gearbox of 130～228cm for swath, the steering mechanism of the form of existing employing jaw clutch is as follows: two splined shaft together support work the central driver gear that has the clutch tooth, left and right both sides are tooth sectors that the clutch tooth is arranged, central driver gear and tooth sector are by tooth embedding clutch, the problem of its existence is because the splined shaft cantilever is longer, rigidity is relatively poor, centering precision is poor, thereby influences the life-span and the clutch reliability of central driver gear gear and tooth sector; The angle angle of the clutch tooth junction of existing central driver gear and tooth sector is 90 °, because it is very frequent that the steering mechanism of grain header uses, the clutch tooth frequent in conjunction with separate, make the surface wear of junction of clutch tooth be exceedingly fast, and the clutch tooth side wearing and tearing near the end are faster, form an inclined-plane, central driver gear and tooth sector clutch tooth are thrown off, influenced walking performance; The entrance angle angle of central driver gear two ends clutch tooth is 20 °, and the problem of existence is that the entrance angle angle is less than normal, and the incision of clutch tooth has some setbacks, thereby influences the disengaging performance of steering mechanism.
Summary of the invention
Goal of the invention of the present utility model is in order to solve existing crawler type grain header gearbox steering mechanism above shortcomings, a kind of novel structure is provided, the rigidity of axle and the centering precision height of gear, the difficult disengagement of central driver gear and tooth sector clutch tooth, the crawler type grain header gearbox steering mechanism that disengaging performance is good.
In order to realize above-mentioned goal of the invention, the utility model has adopted following technical scheme:
Crawler type grain header gearbox steering mechanism, comprise brake axle, band clutch tooth central driver gear, tooth sector, turn to shift fork, return spring and friction plate, central driver gear is connected with tooth sector tooth embedding clutch, and central driver gear vertically is assemblied on the one whole brake axle; Turn to shift fork to be installed in the fork slot of tooth sector, return spring is installed between brake axle and the tooth sector, and friction plate is sleeved on the tooth sector; The angle angle of the clutch tooth junction of described central driver gear and tooth sector is 88 °, and the clutch tooth entrance angle angle of central driver gear is 30 °.
Adopted a kind of crawler type grain header gearbox steering mechanism of technique scheme, central driver gear vertically is assemblied on the one whole brake axle, has improved the rigidity of brake axle, the centering precision height of central driver gear gear and tooth sector.The angle angle of the clutch tooth junction of central driver gear and tooth sector is 88 °, makes central driver gear and tooth sector clutch tooth be difficult for disengagement and wear-resisting, thereby has prolonged the service life of gearbox.The clutch tooth entrance angle angle of central driver gear is 30 °, and the entrance angle angle is big, and the engagement of clutch tooth easily.In sum, the advantage of this crawler type grain header gearbox steering mechanism is a novel structure, the rigidity height of brake axle, and disengaging performance is good, long service life.

Embodiment
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4 the utility model is described further.
Crawler type grain header gearbox steering mechanism as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprise brake axle 1, band clutch tooth central driver gear 2, tooth sector 3, turn to shift fork 4, return spring 6 and friction plate 5.3 tooth embedding clutches are connected central driver gear 2 with tooth sector, central driver gear 2 vertical thermal fit on the one whole brake axle 1, be about to two original splined shafts and make single brake axle 1 into, improved the rigidity of brake axle 1, the centering precision height of central driver gear gear 2 and tooth sector 3.Turn to shift fork 4 to be installed in the fork slot of tooth sector 3, return spring 6 is installed between brake axle 1 and the tooth sector 3, and friction plate 5 is sleeved on the tooth sector 3.
The clutch tooth entrance angle B angle of central driver gear 2 is 30 °, with the entrance angle angle of existing central driver gear 2 clutch teeth is to change 30 ° into by 20 °, the entrance angle angle is big, the engagement of clutch tooth makes the clutch tooth incision of central driver gear 2 and tooth sector 3 be more prone to smooth and easy easily, thereby has improved the disengaging performance of steering mechanism.
