Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Shown in Fig. 1-3, farm work machine special-purpose gearbox in a kind of salt pan is provided with a power input shaft 11, and stirs variable-speed shaft 5, a rotating speed output shaft 3 and an idler shaft 10 in casing; These power input shaft 11 left ends are provided with the belt pulley 6 that is connected with farm work mechanomotive force source, and the middle part is provided with by the 4th gear 7 of power input shaft 11 driven rotary and the 6th gear 9; Stir variable-speed shaft 5 and be provided with the 3rd gear 4 and the triple gear 12 that is used for 9 engagements of the 6th gear; Rotating speed output shaft 3 be provided be used for triple gear 12 engagement the 7th gear 13, octadentate wheel the 14, the 9th gear 15 and with second gear 2 of first gear, 1 engagement; Idler shaft 10 is provided with the 5th gear 8 that is used for 7 engagements of the 4th gear.
The said variable-speed shaft 5 of stirring is splined shaft.
Described variable-speed shaft 5 tops of stirring are provided with two shift forks 17,18, are installed on the declutch shift shaft 16 of stirring variable-speed shaft 5 tops.
Four axles in the utility model gearbox; Its power input shaft 11 act as input power; Stirring variable-speed shaft 5 effects is to realize speed change; Realize that through the spline on the axle its axial slip that cogs carries out speed change, can export three differences rotating speed that advances, realize three different forward velocity; 3 effects of playing outputting power of rotating speed output shaft; 10 of idler shafts are realized gear reversing function, and the gear of stirring on the variable-speed shaft 54 is not then realized neutral with any gear engagement.
The speed change of the utility model gearbox is to rely on the action of said two shift forks so that thereby described gear meshes by different modes is achieved.
The working principle of the utility model is following:
At first, outputting power is given belt pulley 6 from farm work mechanomotive force source, passes to power input shaft 11 by belt pulley 6 and makes it drive the 4th gear 7 and 9 rotations of the 6th gear, and the gear of stirring on the variable-speed shaft 54 meshes itself and the 6th gear 9;
Make the 9th gear 15 engagements on itself and the rotating speed output shaft 3 if stir triple gear 12 on the variable-speed shaft 5; Output speed is realized low speed one retaining to second gear 2 on the rotating speed output shaft 3 with 1 engagement of first gear again, and its rotating speed is 33r/min, and body speed of vehicle is 5km/h;
Make the 7th gear 13 engagements on itself and the rotating speed output shaft 3 realize middling speeds two retainings if stir triple gear 12 on the variable-speed shaft 5;
Make octadentate wheel 14 engagements on itself and the rotating speed output shaft 3 if stir triple gear 12 on the variable-speed shaft 5, then output three retainings at a high speed;
If in the working procedure of an above-mentioned retaining, change the engagement of the 3rd gear 4 and the 6th gear 9 into the 3rd gear 4 and mesh with the 5th gear 8 on the idler shaft 10, then realized reversing gear;
If in the said process, the gear of stirring on the variable-speed shaft 54 is not then realized neutral with any gear engagement.
Stirring the 9th gear 15 on triple gear 12 and the rotating speed output shaft 3 on the variable-speed shaft 5, the 7th gear 13, octadentate wheel 14, to carry out different engagements be to realize through described shift fork 17,18.
To sum up, the special-purpose gearbox of this salt pan farm work machine is totally 5 retainings, comprises that three forward gears, one reverse gear and neutral.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
