Description
Technical field
The utility model relates to a kind of gearbox, particularly relates to a kind of agricultural machinery gearbox, belongs to mechanical field.
Background technique
Current fluid torque converter is mainly used in the hydraulic automatic gearbox of the construction machinery gear boxes such as transloader and automobile, and does not apply on the farm machineries such as corn harvester, wheat harvester, soybean harvester.
Model utility content
The deficiency that the utility model exists for prior art, a kind of agricultural machinery gearbox with fluid torque converter is provided, the clutch of original Manual mechanical gearbox is substituted with fluid torque converter, identical object is reached by different structures, adopt fluid torque converter as the connection between motor and gearbox, adopt hydraulic pressure to control, connection and the disconnection of power between motor and gearbox can be realized more easily.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of agricultural machinery gearbox with fluid torque converter comprises gearbox and torque-converters, converter cover hexagon head bolt is fixed on gear box casing, and wheel cover hexagon head bolt is fixed on converter cover; Input shaft bearings, on wheel cover, freely can be rotated, input shaft is provided with belt pulley, connects between them with flat key, thus the rotation of belt pulley passes to input shaft; Input shaft is connected with connecting wheel, and connecting wheel is connected with pump impeller; Turbine is arranged on turbine shaft by spline, pump impeller rotarily drive hydraulic oil centrifugal motion, impact the blade of turbine, thus make turbine rotation, the rotation of turbine drives turbine shaft to rotate, thus rotary motion is input to transmission internal; Guide wheel is fixedly mounted on wheel stand, and the blade of guide wheel can change the impact direction of hydraulic oil, thus plays the effect of bending moment.
Further, turbine shaft is provided with gear, the gears meshing of gear and gearbox two axle.
Further, with seam location between input shaft and connecting wheel, and bolton is used.
Further, with seam location between connecting wheel and pump impeller, and bolton is used.
The beneficial effects of the utility model are: adopt fluid torque converter to substitute the clutch of original manual type mechanical gearbox, hydraulic control can be realized, the connection of more convenient power between motor and gearbox and disconnection, automatic control can be realized, eliminate the clutch pedal of operator cabin, operator is operated simpler.

In figure: 1, connecting wheel; 2, wheel cover; 3, turbine; 4, guide wheel; 5, pump impeller; 6, converter cover; 7, turbine shaft; 8, gear; 9, spacer; 10, gear box casing; 11, clutch; 12, bearing cap; 13, bearing; 14, two shaftgears; 16, wheel stand; 17, input shaft; 19, belt pulley.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Agricultural machinery gearbox with fluid torque converter comprises gearbox and a torque-converters, and converter cover 6 hexagon head bolts are fixed on gear box casing 10, and wheel cover 2 hexagon head bolt is fixed on converter cover 6; Input shaft 17 bearing 13 is supported on wheel cover 2, freely can rotate, input shaft be provided with belt pulley 19, connect between them with flat key, thus the rotation of belt pulley 19 passes to input shaft 17; Input shaft 17 is connected with connecting wheel 1, and connecting wheel 1 is connected with pump impeller 5; Turbine 3 is arranged on turbine shaft 7 by spline, pump impeller 5 rotarily drive hydraulic oil centrifugal motion, impact the blade of turbine 3, thus turbine 3 is rotated, the rotation of turbine 3 drives turbine shaft 7 to rotate, thus rotary motion is input to transmission internal; Guide wheel 4 is fixedly mounted on wheel stand 16, and the blade of guide wheel 4 can change the impact direction of hydraulic oil, thus plays the effect of bending moment.
Further, turbine shaft 7 is provided with gear 8, and gear 8 engages with gearbox two shaftgear 14.
Further, locate between input shaft 7 and connecting wheel 1 with seam, and by bolton, seam plays certralizing ability, make them coaxial, bolt is used for carrying driving torque, and such input shaft just can drive connecting wheel to rotate together.
Further, locate with seam between connecting wheel 1 and pump impeller 5, and use bolton.
Fluid torque converter is adopted to substitute the clutch of original manual type mechanical gearbox, can realize hydraulic control, the connection of more convenient power between motor and gearbox and disconnection, can realize automatic control, eliminate the clutch pedal of operator cabin, operator is operated simpler.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
