Abstract
The utility model discloses the gearbox of a harvester. The technical proposal of the gearbox of the harvester is that an input shaft is provided with the third-grade gear of the input shaft, the second-grade gear of the input shaft, the first-grade gear of the input shaft and the reverse gear of the input shaft, wherein, the third-grade gear of the input shaft is connected with the second-grade gear of the input shaft through the gear hub sleeve of the input shaft. An intermediate shaft is provided with the third-grade gear of the intermediate shaft frequently engaged with the third-grade gear of the input shaft, the third-grade gear of the intermediate shaft frequently engaged with the second-grade gear of the input shaft, the first-gear of the intermediate shaft frequently engaged with the first-gear of the input shaft and the reverse gear of the intermediate shaft, wherein, the reverse gear of the intermediate shaft is connected with the first-gear of the intermediate shaft through the gear hub sleeve of the intermediate shaft. The reverse gear of the input shaft is connected with the reverse gear of the intermediate shaft through the reverse gear arranged on a reversing shaft. The gears in the utility model can be provided with the straight teeth or the helical teeth; besides, the gears can be flexibly arranged according to the condition, and the utility model which is economical has the advantages that the strength of the gears is high, and the gears are not easily disengaged.
Description
Technical field
The utility model is a kind of grain header gearbox.
Background technology
Present grain header gearbox is the version that directly meshes between the gear, and this structure causes out of supply easily, and the gear arrangement is comparatively fixing, and flexibility is little.
Summary of the invention
The purpose of this utility model is: design a kind of can effectively prevent out of supply, and the grain header gearbox that cost is low, the strength of gear teeth is high.
The utility model comprises housing and power shaft, jackshaft, reversing shaft mounted thereto and the output shaft of differential mechanism is housed and is installed in gear on each, have on the jackshaft and the normal meshed gears of differential mechanism, technical scheme is: power shaft is provided with power shaft third gear, power shaft intermediate gear, one grade of gear of power shaft, power shaft back gear, wherein is connected by power shaft tooth hub sleeve between power shaft third gear and the power shaft intermediate gear; Jackshaft be provided with the third-speed gear of intermediate shaft of the normal engagement of power shaft third gear, with the secondary gear of intermediate shaft of the normal engagement of power shaft intermediate gear, with the one grade of gear of jackshaft and the countershaft reverse gear of the normal engagement of one grade of gear of power shaft, wherein be connected by jackshaft tooth hub sleeve between one grade of gear of countershaft reverse gear and jackshaft; The power shaft back gear is connected by the back gear that is loaded on the reversing shaft with countershaft reverse gear.Gear in the utility model both can be straight-tooth, also can be helical teeth, and gear can according to circumstances be arranged flexibly, and in addition, it also has strength of gear teeth height, is difficult for taking off tooth and economic characteristics.
Specifically add man-hour, gear on power shaft and the jackshaft can be arranged by following mode: be disposed with power shaft third gear, power shaft intermediate gear, one grade of gear of power shaft, power shaft back gear on the power shaft, be disposed with on the jackshaft third-speed gear of intermediate shaft, with differential mechanism meshed gears, secondary gear of intermediate shaft, one grade of gear of jackshaft, countershaft reverse gear.Wherein can make with power shaft and jackshaft one respectively with the normal meshed gears of differential mechanism on one grade of gear of power shaft and the jackshaft.
Use for convenient, jackshaft can be passed by a side of housing and constitute power take-off.
