Abstract
The invention relates to a transmission device, in particular to a transmission device for full-feeding combine harvesters. The transmission device comprises a front drum shaft (1), a variable-speed bevel gear box (2), a tensioning support (3) and a back drum shaft (4) and is characterized in that the front drum shaft (1) is longitudinally arranged in the front of a threshing support of a harvester; the variable-speed bevel gear box (2) comprises a big bevel gear (6), a bevel pinion (5), an output shaft (8) and an output chain wheel (9); the big bevel gear (6) is connected with the front drum shaft (1) through a spline and meshed with the bevel pinion (5); the bevel pinion (5) is connected with one end of the output shaft (8) through the spline; the other end of the output shaft (8) is connected with the output chain wheel (9) through a flat key so as to output the power; and the tensioning support (3) is arranged on the variable-speed bevel gear box (2) through a check ring at one end of the output shaft (8). Compared with a conventional transmission device, the transmission device is compact in structure, simple and convenient for installation, light in weight, low in cost, good in mechanical property and reliable in transmission performance and has the advantages of effectively reducing the noise of whole machine, reducing the vibration of the threshing support and prolonging the service life of the whole machine; and the variable-speed bevel gear box adopts closed lubrication to ensure that high-speed revolution part of the transmission device is sufficiently lubricated and the service life of the transmission structure is prolonged.
Description
Technical field
The present invention relates to a kind of transmission device, the transmission device that a kind of more precisely all feeding-in combine is used.
Background technology
Transmission device is the vitals that combine is realized crop harvesting, and it mainly acts on is the transmission that realizes power, and its reliability and stability directly has influence on the operating efficiency and the service life of grain header.The most threshing forms that adopt twin-roll of present all feeding-in combine; And for twin-roll full feeding rice wheat combine, its drive mechanism is arranged in homonymy, the transmission of this form; Stroke is distant basically; Need multistage transmission could realize that this is increasing manufacturing cost virtually, strengthened the loss of power in the transmission course.When increasing transmission progression, the unreliable coefficient of transmission has also become greatly, when certain transmission link wherein goes wrong, when serious even can have influence on the use of complete machine, the decline that directly causes gathering in the crops efficient.And the drive mechanism of this form is because the transmission stroke is long, progression is many, and noise and vibration all must inevitably strengthen.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of compact conformation, reliable transmission, quality light and handy, easy for installation, have the transmission device that the twin-roll all feeding-in combine of practicality is used.
The present invention is for achieving the above object; Adopt following technical scheme: the transmission device that a kind of all feeding-in combine is used; It comprises front roll axle, speed change umbrella gear box, tensioning support and back roll axle, and it is anterior that said front roll axle is installed in the harvester threshing support, is vertical layout; When realizing the input of front roll axle power, power is transported to the speed change umbrella gear box; Said speed change umbrella gear box comprises large bevel gear, cone pinion, output shaft and output chain gear; Wherein large bevel gear is connected with the front roll axle through spline; Realize the input of power, with cone pinion for being connected with a joggle, cone pinion is connected through spline with an end of output shaft; The other end of output shaft is connected with output chain gear through flat key, and power is exported; Said tensioning support is installed on the speed change umbrella gear box through the back-up ring of output shaft one end, and the chain between tensioning speed change umbrella gear box and the back roll axle makes driving chain be in suitable tensioning state, steadily transmission reliably.
Said speed change umbrella gear box connects through bolt, is fixedly mounted on the gearbox installing plate.
Said back roll axle is installed in the Frame for thresher rear portion, is lateral arrangement, is connected with input sprocket through flat key, and then drives whole back roll threshing.
Said output gear is connected through chain with the input gear.
Beneficial effect of the present invention: than existing drive mechanism, compact conformation not only, simple installation; Light weight, low, the good mechanical property of cost, transmission performance is reliable, and has effectively reduced the noise of complete machine; Reduced the vibration of Frame for thresher, the life-span of complete machine is improved; Speed change umbrella tooth case adopts enclosed lubricated, guarantees the high speed rotating position sufficient lubrication of transmission device, makes be improved the service life of drive mechanism.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further elaboration.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of speed change umbrella gear box of the present invention.
Among the figure 1, front roll axle 2, speed change umbrella gear box 3, tensioning support 4, back roll axle 5, cone pinion 6, large bevel gear 7, gearbox installing plate 8, output shaft 9, output chain gear 10, input sprocket
Embodiment
The transmission device of using like Fig. 1, a kind of all feeding-in combine shown in Figure 2; It comprises front roll axle 1, speed change umbrella gear box 2, tensioning support 3 and back roll axle 4; It is anterior that said front roll axle 1 is installed in the harvester threshing support; Be vertical layout, when realizing the input of front roll axle 1 power, power be transported to speed change umbrella gear box 2; Said speed change umbrella gear box 2 comprises large bevel gear 6, cone pinion 5, output shaft 8 and output chain gear 9; Wherein large bevel gear 6 is connected with front roll axle 1 through spline; Realize the input of power, with cone pinion 5 for being connected with a joggle, cone pinion 5 is connected through spline with an end of output shaft 8; The other end of output shaft 8 is connected with output chain gear 9 through flat key, and power is exported; Said tensioning support 3 is installed on the speed change umbrella gear box 2 through the back-up ring of output shaft 8 one ends, and the chain between tensioning speed change umbrella gear box 2 and the back roll axle 4 makes driving chain be in suitable tensioning state, steadily transmission reliably.
The present invention can be used for the transmission of twin-roll grain header, and power is a side of drum shaft 1 in the past, through belt or chain input; The opposite side of the past drum shaft 1; Through utilizing being connected of large bevel gears 6 in spline and the speed change umbrella gear box 2 on the front roll axle 1, drive cone pinions 5 by large bevel gear 6, cone pinion 5 drives output chain gears 9 through output shaft 8 and realizes power output; At last; Drive input sprocket 10 by output chain gear 9 through chain, thereby further drive the rotation of back roll axle 4, realize the transmission process of whole transmission device.
