Description
One, affiliated technical field
The utility model is the gearbox that a kind of medial and small construction machinery is used.
Two, background technique
Along with developing rapidly of rural economy, the demand of engineering machinery is also more and more, but the gearbox that uses on the present medial and small construction machinery of producing, majority is the gearbox that adopts tractor with small four wheels, or improve slightly on its basis, therefore exist complex structure, cost height, speed change gear too many (less because of job area, as to there is no need too much gear), complicated operation, characteristics such as dumb.
The gearbox that the purpose of this utility model provides is a kind of suitable medial and small construction machinery, simple in structure, easy to operate, flexible, cost is low.
For achieving the above object, the technological scheme that the utility model is taked is to be made up of casing, power input shaft, servo axis, variable-speed shaft, pto, gear I, gear II, gear III, gear IV, gear VI, gear VII, gear VIII, gear IX, gear controller, advance and retreat Effector etc.Power input shaft, servo axis, variable-speed shaft, pto, gear I, gear II, gear III, gear IV, gear VI, gear VII, gear VIII, gear IX are contained in the casing.One end of power input shaft stretches out casing, connects with the power plant of engineering machinery, provides power by the power plant (as diesel engine) of engineering machinery.Two ends of pto all stretch out casing, connect with the forward and backward ransaxle of engineering machinery respectively, drive the walking of engineering machinery.Gear I, gear VI are fixed on the power input shaft.Gear II, gear VII are fixed on the servo axis.Gear III, gear VIII be installed on the variable-speed shaft, and can slippage on variable-speed shaft.Gear IV, gear IX are fixed on the pto.Gear VI and gear VII engagement.Gear III and gear II or gear I engagement, promptly gear III by the advance and retreat Effector stir with gear II engagement or with gear I engagement, realize advancing or retreating walking of engineering machinery.Gear VIII and gear IX or gear IV engagement in like manner, are meshed or are meshed with gear IV by gear controller handsetting gear VIII and gear IX, realize the high speed or the low speed walking of engineering machinery.The advance and retreat Effector is made up of shift fork I, driving lever I, lever I, operating handle I etc., lever I is contained in the casing, and the end of lever I stretches out casing and operating handle I is housed, and the other end of lever I connects with driving lever I, the other end of driving lever I is equipped with shift fork I, and shift fork I is stuck on the gear III.Gear controller is made up of shift fork II, driving lever II, lever II, operating handle II etc., lever II is contained in the casing, the end of lever II stretches out casing and operating handle II is housed, the other end of lever II connects with driving lever II, the other end of driving lever II is equipped with shift fork II, and shift fork II is stuck on the gear VIII.
Its working principle:
Power input shaft driven gear I, gear VI rotate, gear VI rotates by the gear II that gear VII drives on servo axis and the servo axis, the operating handle I of operation advance and retreat Effector drives shift fork I by lever I, driving lever I, shift fork I handsetting gear III and gear II or gear I engagement.When meshing with gear II, drive variable-speed shaft by gear II by gear III, variable-speed shaft drives pto by gear VIII and gear IV or gear IX, and the forward and backward ransaxle of pto drive engineering machinery makes engineering machinery advance (or retreating).When gear III and gear I engagement, power input shaft directly drives the variable-speed shaft backward rotation by gear I, gear III, drives pto by gear VIII by gear IV or gear IX again, makes engineering machinery retreat (or advancing).Walk at a high speed or low speed when walking when the needs engineering machinery, only need to handle the operating handle II of gear controller,, can realize that just the high speed of engineering machinery or low speed walks by lever II, driving lever II, shift fork II handsetting gear VIII and gear IV or gear IX engagement.
Therefore, the utlity model has characteristics such as simple in structure, easy to operate, that cost is low.
Four, description of drawings

Fig. 2 launches schematic representation for the utility model gear transmission.
Five, specific implementation method
As shown in drawings, the utility model is made up of casing 5, power input shaft 21, servo axis 22, variable-speed shaft 23, pto 24, gear I1, gear II2, gear III3, gear IV4, gear VI6, gear VII7, gear VIII8, gear IX9, gear controller, advance and retreat Effector etc.Gear I1, gear VI6 are fixed on the power input shaft 21.One end of power input shaft 21 stretches out casing 5 and connects with power plant (as diesel engine).Gear II2, gear VII7 are fixed on the servo axis 22, and gear III3, gear VIII8 be installed on the variable-speed shaft 23, and can slippage on variable-speed shaft 23.Gear IV4, gear IX9 are fixed on the pto 24.Two ends of pto 24 stretch out casing 5 and connect with forward and backward ransaxle.The advance and retreat Effector is made up of shift fork I13, driving lever I12, lever I16, operating handle I17 etc., lever I16 is contained in the casing 5, the end of lever I16 stretches out casing 5 and operating handle I17 is housed, the other end of lever I16 connects with driving lever I12, the other end of driving lever I12 is equipped with shift fork I13, and shift fork I13 is stuck on the gear III3.When manipulation bar I17, operating handle I17 drives lever I16, and lever I16 drives driving lever I12, driving lever I12 drives shift fork I13, shift fork I13 handsetting gear III3 moves on variable-speed shaft 23, makes gear III3 and gear II2 or gear I1 engagement, realizes advancing or retreating.In like manner, gear controller is made up of shift fork II15, driving lever II14, lever II18, operating handle II19 etc., shift fork II15 is stuck on the gear VIII8, manipulation bar II19 is by lever II18, driving lever II14, shift fork II15, handsetting gear VIII8 moves on variable-speed shaft 23 and gear IV4 or gear IX9 engagement, realizes the speed change of high, low speed.Therefore, the utlity model has characteristics such as simple in structure, easy to operate, flexible, that cost is low.
