Detailed description of the invention
For the benefit of the understanding to structure of the present utility model, illustrates below in conjunction with drawings and Examples。
The structural representation of the rotary tillage boat main-gear box that Fig. 1 provides for this utility model, the structural representation that in the rotary tillage boat main-gear box that Fig. 2 provides for this utility model, meshing ring and meshing part coordinate。In conjunction with shown in Fig. 1 and Fig. 2, this utility model provides a kind of rotary tillage boat main-gear box, including: there is the housing 10 installing cavity 11, described installation cavity 11 bridges reverse gear output shaft the 20, first axle the 30, second axle 40 and the 3rd axle 50 from top to bottom successively, and the two ends of described first axle 30 and the 3rd axle 50 are all extended described housing 10 and arranged。
It is positioned at the first axle 30 installing cavity 11 and is provided with meshing assembly 31, the axle two third gear assembly 32 of one grade of an axle and an axle power output gear seaming element 33。
It is positioned at the output shaft 20 that reverses gear installing cavity 11 and is provided with slide with the meshing assembly of one grade of an axle 31 and an axle power output gear seaming element 33 respectively reverse gear meshing assembly 21 and the output gear seaming element 22 of reversing gear that suit。
The second axle 40 being positioned at installation cavity body is provided with the meshing assembly 41 of one grade of two axle suited with the slip of one grade of an axle meshing assembly 31, the meshing assembly 42 of two grades of two axle suited with axle two third gear assembly 32 1 Slideslip, and slide the two meshing assemblies 43 of axle third gear that suit with axle two third gear assembly 32 opposite side, the 3rd axle 50 is provided with the three meshing assemblies 51 of through-drive suited with the two meshing assemblies of axle third gear 43。
In the present embodiment, the diameter of described one grade of meshing assembly 31 of an axle is arranged less than the diameter of described reverse gear meshing assembly 21 and the meshing assembly 41 of one grade of two axles。Further, a described axle two third gear assembly 32 includes axle intermediate gear assembly 321 and an axle third gear assembly 322 of integral type, the diameter of a described axle intermediate gear assembly 321 is arranged less than the diameter of described two grades of meshing assemblies 42 of two axles, and the diameter of a described axle third gear assembly 322 is arranged more than the diameter of the two meshing assemblies 43 of axle third gear。
Further, the one meshing assembly 31 of one grade of axle, one axle two third gear assembly 32, one axle power output gear seaming element 33, reverse gear meshing assembly 21, reverse gear output gear seaming element 22, the two meshing assemblies 41 of one grade of axle, the two meshing assemblies 42 of two grades of axle, the two meshing assemblies of axle third gear 43 and the meshing assembly of three through-drive 51 all include meshing ring 61, it is located on meshing ring two and encloses spaced meshing part installing spaces 62 and meshing part 63 that multiple spacer rings of being located on two circles meshing part installing space 62 set, and two the meshing part 63 enclosed on meshing part installing space 62 mutually stagger setting。Further, described meshing ring 61 and described meshing part 63 are detachably connected with, when damaging for indivedual meshing parts 63, can the meshing part 63 of this damage of quick replacement, save cost and fast and easy, in the present embodiment, described meshing ring 61 is disk ring, and meshing part 63 is meshing cube of bar。Two enclose meshing cube of bar spaced set on the first lap in described meshing part installing space 62, the interval region of meshing cube of adjacent bar is arranged with described meshing cube of bar equal in width, and the sidepiece of the interval region position of the corresponding described first lap of meshing cube of bar on the second circle is arranged。This setting makes can be seamless meshing between the meshing unit of each correspondence, improves meshing effect。And when there is gap in the meshing cube of bar suiting two meshing unit of setting, the noise that the meshing collision of high speed sends is big, long-time collision makes malformation, shortens the service life of change speed gear box, and therefore, this setting also reduces the running noise of change speed gear box, longer service life。
The rotary tillage boat main-gear box that this utility model provides, control the first axle by shifting fork bar to move, the one meshing assembly of one grade of axle meshing realization corresponding to the meshing assembly that reverses gear is reversed gear operation, the corresponding meshing realization one grade of operation of advance of one grade of meshing assembly of the one meshing assembly of one grade of axle and two axles, the two grades of meshing assemblies in two grades of sides of one axle two third gear assembly and two axles corresponding meshing realize advance two grades of operations, and one axle two third gear assembly third gear side and the two meshing assembly of axle third gear corresponding meshing realization advance third gear operations, this arranges and can meet most of rotary tillage requirement, additionally, circle two in each meshing assembly arranges the meshing part on meshing ring and mutually staggers setting, while improve the meshing effect of main-gear box, also extend the service life of decelerator。
Above in association with accompanying drawing embodiment, this utility model being described in detail, this utility model can be made many variations example by those skilled in the art according to the above description。Thus, some details in embodiment should not constitute restriction of the present utility model, this utility model by the scope that defines using appended claims as protection domain。
