Description
Technical field
The present invention relates to a kind of gear-box for baling press, relate in particular to a kind of gear-box of the baling press for herbage, belong to agricultural machinery technical field.
Background technique
The gear-box of conventional herbage baling press is to adopt tractor to drive, and power, from the diesel engine output of tractor, passes to the input shaft of baling press through transmission shaft, then through a pair of spiral bevel gear or a pair of spiral bevel gear, adds primary cylinder gear and sends power to baling press.When baling press need to be worked, transmission shaft and baling press need be connected; When baling press is not worked or vacant lot when walking, need the disconnection that connects with baling press by transmission shaft.This mode operates comparatively complicated, cannot realize continuous control; During baling press conversion working state, need to change the coupled situation of transmission shaft and baling press, inconvenient operation, inefficiency.
For solving above-mentioned technological deficiency, this case produces thus.
Summary of the invention
The object of this invention is to provide a kind of structural configuration compactness, beautiful shape, good reliability, volume is little, transmission efficiency is high, the easy to operate high class gear case for herbage baling press.
For achieving the above object, the technological scheme that the present invention takes is as follows:
A kind of gear-box for baling press, comprise casing, case lid, input gear axle, jack shaft and output shaft, described input gear axle consists of input shaft and the input gear that is positioned at input shaft end, input shaft and input gear are integral type structure, and input gear axle is inserted on casing by clutch shaft bearing and the second bearing; On jack shaft, be provided with jack shaft is the jack shaft spline of integral type structure, on jack shaft, hot jacket has intermediate gear, on jack shaft, be also set with regulation and control gear one and regulation and control gear two, between regulation and control gear one and regulation and control gear two, flip sleeve is equipped with tooth cover, tooth cover can move left and right on the jack shaft spline of jack shaft, to adjust the different working state of gear-box, realize two working staties of baling press and a halted state, regulation and control gear is bearing on jack shaft by the 7th bearing, and jack shaft is fixed between casing and case lid by the 3rd bearing and the 4th bearing; On output shaft, be set with output gear, output gear is fixedly installed between casing and case lid by the 5th bearing and the 6th bearing; Input gear axle one end is connected with power system, and the other end meshes by input gear and intermediate gear, between regulation and control gear and jack shaft, by tooth cover, realizes power transmission, and regulation and control gear and output gear are used in conjunction with.
For realizing using effect better, further arranging of technique scheme is as follows:
The number of teeth of two described regulation and control gears is different.
Described tooth cover is to be realized and being moved left and right by shift fork, and shift fork is installed on casing, by power system, is controlled, and the control of this power system can be controlled or manual mode for air cylinder driven.
Described tooth cover is realized and being moved left and right by manual or air cylinder driven, and cylinder is controlled by power system.
Described input gear is input spiral bevel gear, and clutch shaft bearing and the second bearing are tapered roller bearing.
Described intermediate gear is spiral bevel gear, and regulation and control gear is cylindrical gears, and the 3rd bearing and the 4th bearing are tapered roller bearing.
Described output gear is cylindrical gears, and the 5th bearing and the 6th bearing are tapered roller bearing.
In using process, when the slippage of tooth cover is to the left time, the regulation and control gear that is positioned at left side connects with tooth cover, jack shaft, jack shaft spline, intermediate gear and left side regulation and control gear be rotating in same direction simultaneously, power imports into by input bevel gear shaft, through intermediate gear, jack shaft, jack shaft spline, tooth cover, left side regulation and control gear, left side output gear, finally by output shaft, spread out of; When the slippage of tooth cover is to the right time, the regulation and control gear that is positioned at right side connects with tooth cover, jack shaft, jack shaft spline, intermediate gear and right side regulation and control gear be rotating in same direction simultaneously, power imports into by input bevel gear shaft, through intermediate gear, jack shaft, jack shaft spline, tooth cover, right side regulation and control gear, right side output gear, finally by output shaft, spread out of; In the middle of tooth cover is positioned at two regulation and control gears and during not with arbitrary regulation and control Gear Contact, jack shaft and intermediate gear dally, owing to not having power to be transported to output shaft, output shaft does not rotate.
Because regulation and control gear in left side in the present invention is different from the number of teeth of right side regulation and control gear, when tooth overlaps the regulation and control gear couplings less with the number of teeth, output speed is lower, and it is slower that baling press is picked up the speed of careless speed and baling grass, is applicable to careless fewer general mode; When tooth overlaps the regulation and control gear couplings more with the number of teeth, output shaft rotating speed is higher, and baling press is picked up the speed of careless speed and baling grass, is applicable to the many fine patterns of grass; When there is idle running in jack shaft, owing to there is no power output, thereby can meet the demand of vacant lot walking or off working state, the cooperating of tooth cover, regulation and control gear can be realized the regulation and control of two kinds of rotating speeds, three gears, thereby more convenient operation, and working efficiency is higher; Input gear and input shaft adopt integral structure to form input gear axle, compare with conventional split-type structural, and its stability and reliability improve, transmission performance also improves, and this modular design has improved efficiency of assembling greatly, be convenient to maintenance and maintenance.
The present invention is by the structure of appropriate design gear-box, meeting under reliability prerequisite, by the input block of gear-box (input gear, input shaft etc.), intermediate member (jack shaft, jack shaft spline, intermediate gear, regulation and control gear, tooth cover etc.) and three function part integrations of output block (output shaft, output gear etc.), modularization, be convenient to assembling, maintenance and maintenance, meet better baling press operating mode, compared with prior art, there is structural configuration compactness, beautiful shape, good reliability, the advantage such as easy to operate.
