Abstract
The utility model relates to a wheeled self-propelled harvester gearbox, which is characterized in that a second-gear driving gear (6) on an input shaft and a reverse-gear duplicate gear (8) are constant mesh gears, and the reverse-gear duplicate gear and one first-gear reverse-gear driven gear (15) on a middle shaft are long mesh gears. Second-gear and third-gear spline housings (12) for connecting all driven gears and a first-gear spline housing (17) are respectively provided with anti-gear-stripping grooves. On the basis of the advantages of compact structure, small size, light weight and low cost of the original gearbox, the wheeled self-propelled harvester gearbox additionally has the characteristics of flexible gear changing, difficult gear stripping, good bearing lubrication effect, difficult bearing damage, long service life of equipment, strong reliability, and the like.
Description
Technical field
The utility model relates to a kind of grain header gearbox, particularly a kind of self-propelled wheel-type grain header gearbox.
Background technology
At present, be mainly used in the walking gearbox on the self-propelled wheel-type grain header, its compact conformation, characteristics such as volume is little, in light weight, gear shift is flexible, cost is low are used on the self-propelled grain cbmbine harvester at home.This speed changer be one by clutch, differential mechanism, the uni-drive gear box that hand brake etc. are formed, have three forward gears and a backward gear, by input belt wheel input power, be input to by the clutch assembly on the power shaft on the power shaft of speed changer, power shaft is provided with the driving gear of three drive shifts, one one reverse gear balladeur train and two third gear balladeur trains are housed on the jackshaft, again by intermediate drive gear through-drive to the large straight gear that is contained on the differential mechanism, be transferred to the walking movement that differential box and semiaxis outputting power drive self-propelled grain cbmbine harvester at last.But in use have following shortcoming: 1 when gear shift complete machine must stop or speed is dropped to low especially speed, just can shift gears, have abnormal sound easily to beat tooth when shifting gears dumb, gear shift, and out of supply easily.Bearing on the 2 input gear shafts is when neutral gear, and lubricated insufficient, bearing damages easily.
Summary of the invention
The purpose of this utility model is for the self-propelled wheel-type grain header provides a kind of novel gearbox, by input belt wheel (1), clutch assembly (2), differential mechanism large straight gear (3), intermediate drive gear axle (4), third speed drive gear (5), second gear driving gear (6), input gear shaft (7), reverse dual-linked gear (8), hand-made driving wheel (9), third gear driven gear (10), two third gear connect gear (11), two third gear spline housings (12), differential assembly (13), second gear driven gear (14), one reverse gear driven gear (15), one reverse gear connects gear (16), one reverse gear spline housing (17) is formed.It is characterized in that the second gear driving gear (6) on the power shaft is a constant mesh gear with reverse dual-linked gear (8), one of them the reverse gear driven gear (15) on reverse dual-linked gear and the jackshaft is long meshing gear.Be used to connect on the two third gear spline housings (12), a reverse gear spline housing (17) of each driven gear and be respectively equipped with anti-groove out of supply.
The utility model is based on the basis that compact conformation, volume are little, in light weight, cost is low of former gearbox, other have gear shift flexibly, be difficult for out of supply, bearing lubrication is effective, not fragile bearing, service life of equipment is long and characteristics such as good reliability.For reaching above purpose, the technical scheme that the utility model is taked is: power shaft is provided with third speed drive gear, the second gear driving gear, one grade of driving gear of power shaft, wherein the reverse dual-linked gear on second gear driving gear and the reversing shaft often meshes, jackshaft is provided with the third gear driven gear, the second gear driven gear, two of one reverse gear driven gears, wherein third gear driven gear and third speed drive gear often mesh, second gear driven gear and second gear driving gear are engagement, third gear driven gear and second gear driven gear, connecting gear by two third gear is connected with two third gear spline housings, one grade of driving gear of one reverse gear driven gear and power shaft often meshes, another reverse gear driven gear and reverse dual-linked gear often mesh, two one reverse gear driven gears, connect gear by a reverse gear and be connected, on a reverse gear spline housing and two third gear spline housings, be respectively equipped with the anticreep retaining groove with a reverse gear spline housing.Gear in the utility model speed changer is the flexible arrangement position according to circumstances, in addition, the anticreep retaining groove is arranged on spline housing, is difficult for the characteristics of out of supply and economic use.Be mainly used in the walking gearbox on the self-propelled wheel-type grain header, have characteristics such as compact conformation, volume is little, in light weight, gear shift is flexible, cost is low, wheeledly on self-propelled grain cbmbine harvester, use.
