Abstract
The invention relates to a transmission gear, in particular to a novel transmission gear for a full-feeding harvester. The novel transmission gear for the full-feeding harvester comprises a front drum shaft (1), a variable speed bevel gear box (2), a tensioning support (3) and a rear drum shaft (4). The novel transmission gear for the full-feeding harvester is characterized in that the front drum shaft (1) is mounted on the front portion of a harvester threshing support and is longitudinally arranged; the variable speed bevel gear box (2) comprises a big bevel gear (6), a small bevel gear (5), an output shaft (8) and an output chain wheel (9); the tensioning support (3) is mounted on the variable speed bevel gear box (2) through a check ring at one end of the output shaft (8). Compared with an existing transmission structure, the structure is compact, mounting is simple and convenient, weight is low, cost is low, the mechanical property is good, the transmission performance is reliable, noise of the complete machine is effectively lowered, vibration of the threshing support is reduced, and the service life of the complete machine is prolonged.
Description
Technical field
The present invention relates to a kind of transmission device, the new drive device that a kind of full feeding harvester is used more precisely.
Background technology
Transmission device is the vitals that combine is realized crop harvesting, and its Main Function is the transmission that realizes power, and its reliability and stability directly has influence on operating efficiency and the service life of grain header.The most threshing forms that adopt twin-roll of current 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 substantially distant, need Multi-stage transmission to realize, this is increasing manufacturing cost virtually, has strengthened the loss of power in transmitting procedure.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, directly causes the decline of efficiency of crop.And the drive mechanism of this form is because transmission stroke is long, progression is many, noise and vibration all must inevitably strengthen.
Summary of the invention
The object 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, there is the transmission device that the twin-roll all feeding-in combine of practicality is used.
The present invention is for achieving the above object, by the following technical solutions: the new drive device that a kind of full feeding harvester is used, it comprises front roll axle, speed change umbrella gear box, tensioning support and back roll axle, it is anterior that described front roll axle is arranged on harvester threshing support, be longitudinal layout, when realizing the input of front roll axle power, power is transported to speed change umbrella gear box; Described speed change umbrella gear box comprises large bevel gear, cone pinion, output shaft and output chain gear, wherein large bevel gear is connected with front roll axle by spline, realize the input of power, with cone pinion for being connected with a joggle, spline joint is passed through in one end of cone pinion and output shaft, the other end of output shaft is connected with output chain gear by flat key, and power is exported; Described tensioning support is arranged on speed change umbrella gear box by the back-up ring of output shaft one end, and the chain between tensioning speed change umbrella gear box and back roll axle makes driving chain in suitable tensioning state, steadily transmission reliably.
Described speed change umbrella gear box is bolted, and is fixedly mounted on gearbox installing plate.
Described back roll axle is arranged on Frame for thresher rear portion, is lateral arrangement, is connected, and then drives whole back roll threshing by flat key with input sprocket.
Described output gear is connected by chain with input gear.
Beneficial effect of the present invention: than existing drive mechanism, compact conformation not only, simple installation, quality is light, cost is low, good mechanical property, and transmission performance is reliable, and effectively reduces 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 Rotation Speed position sufficient lubrication of transmission device, and is improved the service life of drive mechanism.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further elaborated.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of speed change umbrella gear box of the present invention.
In 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 new drive device that a kind of full feeding harvester is as shown in Figure 1 and Figure 2 used, it comprises front roll axle 1, speed change umbrella gear box 2, tensioning support 3 and back roll axle 4, it is anterior that described front roll axle 1 is arranged on harvester threshing support, be longitudinal layout, when realizing the 1 power input of front roll axle, power is transported to speed change umbrella gear box 2; Described 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 by spline, realize the input of power, with cone pinion 5 for being connected with a joggle, cone pinion 5 passes through spline joint with one end of output shaft 8, the other end of output shaft 8 is connected with output chain gear 9 by flat key, and power is exported; Described tensioning support 3 is arranged on speed change umbrella gear box 2 by the back-up ring of output shaft 8 one end, and the chain between tensioning speed change umbrella gear box 2 and back roll axle 4 makes driving chain in suitable tensioning state, steadily transmission reliably.
The present invention can be used for the transmission of twin-roll grain header, power is a side of drum shaft 1 in the past, by belt or chain, input, the opposite side of the past drum shaft 1, by utilizing being connected of spline on front roll axle 1 and the interior large bevel gear 6 of speed change umbrella gear box 2, by large bevel gear 6, drive cone pinion 5, cone pinion 5 drives output chain gear 9 to realize power by output shaft 8 and exports, finally, by output chain gear 9, pass through chain-driving input sprocket 10, thereby further drive the rotation of back roll axle 4, realize the transmission process of whole transmission device.
