Abstract
The utility model discloses an intermediate gearing box of a large rotavator matched with a large tractor, which comprises an intermediate box body, and is characterized in that the intermediate box body is internally provided with a bevel gear shaft; a second shaft, a third shaft and a transition shaft are arranged in the intermediate box body in order; the bevel gear shaft is provided with a small bevel gear; the second shaft and the third shaft are respectively provided with a big bevel gear of a second shaft horizontal gear, and a third shaft horizontal gear; the transition shaft is provided with a transition gear; the lower part of the intermediate box body is provided with a cutter shaft spline shaft which is provided with a cutter shaft gear and a cutter shaft connecting disc. The utility model realizes the working requirement for matching with the large rotavator, has the advantages of reasonable structure, convenient assemble and maintenance, long service life and the like, and is applicable to the large rotavator with 120 to 240 HP.
Description
Technical field
The utility model relates to a kind of transmission case, particularly a kind of with drag supporting large-scale rotovator middle driving box greatly.
Background technology
Also do not drag supporting large-scale rotovator middle driving box in the prior art specially and greatly.Then replace when needed, thereby have following defective with middle-size and small-size rotovator middle driving box: the one, the rotovator centre-height is unreasonable, and the inter-axle shaft angle is excessive, can't guarantee normal use; The 2nd, the cutter shaft that on medium and small rotovator basic component, extends, the lengthening framework realizes cooperating large sized tractor to use, and casing and gear equal strength are low, mechanical failure rate height.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provide a kind of simple and reasonable, fault rate is low with drag supporting large-scale rotovator middle driving box greatly.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of and drags supporting large-scale rotovator middle driving box greatly, comprise middle housing, be characterized in, be provided with bevel gear shaft in the middle housing, and in middle housing, laterally be provided with two, three and transition axis successively, bevel gear shaft is provided with bevel pinion, two are provided with bevel gear wheel, two horizontal gears, three are provided with three horizontal gears, transition axis is provided with transition gear, the bottom of middle housing is provided with the cutter shaft splined shaft, and the cutter shaft splined shaft is provided with knife shaft gear and cutter shaft terminal pad.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described with drag supporting large-scale rotovator middle driving box greatly, be characterized in, described bevel gear shaft and with the power transmission shaft angle of the supporting tractor of middle driving box be 0 °-8 °.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described with drag supporting large-scale rotovator middle driving box greatly, be characterized in that described bevel gear shaft is with parallel with the power transmission shaft of the supporting tractor of middle driving box.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described with drag supporting large-scale rotovator middle driving box greatly, be characterized in that the centre distance of described cutter shaft splined shaft and bevel gear shaft is the 550-720 millimeter, preferred 573 millimeters.
During use, tractor motive power output shaft reaches bevel gear shaft by power transmission shaft with power, after bevel gear wheel reaches two horizontal gears, three horizontal gears, transition gear, knife shaft gear and cutter shaft splined shafts successively, reach the cutter shaft terminal pad again, drive rotary blade on the rotary tiller shaft by the cutter shaft terminal pad and realize that rotary tillage cuts soil.Compared with prior art, the utility model can be realized the job requirement used with big tractor, has that structure is more reasonable, advantages such as assembling and easy to maintenance, long service life, is fit to and 120 to 240 horsepowers of supporting uses of large sized tractor.
