Description
Technical field
The utility model relates to a kind of transmission device, relates in particular to a kind of transplanter planetary gear train transmission device, belongs to agricultural machinery technological field.
Background technique
The power transmission of transplanter all is to adopt motor to carry out power output through the association that oil pump drives the oil hydraulic motor composition now; Hereinafter to be referred as the HST unit, its advantage is to have realized stepless speed regulation very easily, is the structural type of approving fully at present; Kubo field, the Jing Guan of Japan; The farm machinery of representative advanced levels such as the world of Korea S, Datong District, Japan all adopts this drive mechanism, and its transmission efficiency is about 65%, and rotating speed is lost in about 8% in the time of at full capacity.The foreign horse of Japan works out a kind of mechanical transmission and hydraulic transmission dual-output device; Automatically convert the output of mechanical transmission power during high rotating speed to; Automatically switch into hydraulic transmission power output during the slow-speed of revolution,, and can bring up to more than 85% because of the complete machine working efficiency because most of time works under high revolution; Can guarantee the stationarity and the flexibility of complete machine during slow speed again, represent the our times advanced level.China is large agricultural country in the world, and large-scale farm machinery demand and yielding capacity are all very big, does not also have the intellectual property of oneself.
Summary of the invention
In order to address the above problem, the purpose of the utility model is to provide a kind of transplanter planetary gear train transmission device.This model utility is a kind of brand-new planetary gear train transmission device; With engine output shaft power through gear, outreach gear, central gear is transferred to planetary pinion; Hydraulic motor output shaft power with the HST unit also is transferred to planetary pinion through the planet external toothing in addition; Unification is at last exported by the planetary wheel carrier transmission in the planetary gear train driving mechanism; Reach the parallelly connected output of mechanical transmission, so promptly guaranteed hydraulicdriven stationarity of slow-speed of revolution small-power and flexibility, high efficiency in the time of can guaranteeing the high-power transmission of high rotating speed again and the problem that does not throw switch with the oil hydraulic motor transmission.
The utility model solves the technological scheme that its technical problem adopted: transplanter planetary gear train transmission device; By HST unit, engine output shaft, driving gear, HST unit output shaft, planet external toothing, planetary wheel carrier, outreach gear, planetary pinion, central gear, output shaft, total clutch is formed; Engine output shaft is in transmission connection to by driving gear through the HST unit and outreaches on the gear; The central gear that outreaches in gear and the planetary gear train driving mechanism is that duplicate gear and sky are enclosed within on the output shaft; Central gear and planetary pinion are in transmission connection, and engine output shaft also is in transmission connection by planet external toothing and the planetary pinion that HST unit output shaft is fixedly connected through the HST unit simultaneously.Planetary pinion is connected with output shaft through the planetary wheel carrier that its center is rotationally connected, and output shaft is through total clutch outputting power.
Working principle is:
One, after the engine start; When under any rotating speed, rotating; Oil hydraulic motor in the HST unit rotates with maximum output; This moment, engine output shaft and HST unit output shaft rotated (HST unit output shaft rotating speed=engine output shaft rotating speed * 94%) with same rotational speed, and planetary gear train is output not.
Transmission process: 1, motor--HST unit (association of oil pump and oil hydraulic motor)--engine output shaft--driving gear----central gear---planetary pinion that outreaches gear;
2, motor--HST unit----HST unit output shaft--planet external toothing---planetary pinion;
Conclusion: because the rotating speed of central gear and planet external toothing just in time drives the planetary pinion rotation, so planetary planetary wheel carrier is motionless, promptly output shaft does not rotate output, and the output shaft rotating speed is zero;
Two, under the constant situation of engine speed, change the output quantity of oil pump oil in the HST unit, dropped to gradually by maximum output and be output as zero, the rotating speed of planetary gear train output shaft is increased to maximum gradually from zero so.
Transmission process: 1, motor--HST unit (association of oil pump and oil hydraulic motor)--engine output shaft--driving gear----central gear---planetary pinion that outreaches gear;
2, motor--HST unit----HST unit output shaft--planet external toothing---planetary pinion;
Conclusion: when the output shaft rotating speed of HST unit reduces gradually; Because when the rotating speed of central gear and planet external toothing drives the planetary pinion rotation; Not only make the planetary pinion rotation, and planetary pinion is revolved round the sun around central gear, this has just driven planetary planetary wheel carrier and has rotated; Output shaft and planetary wheel carrier are rigidly connected, so output shaft rotates; When HST unit output shaft rotating speed drops to after zero from the highest, planetary gear train promptly is converted into mechanical speed change by stepless change, and its efficient more than 60% during by synthetic speed change rises to more than 85%.
Three, under the constant situation of engine speed, change the output quantity of oil pump oil in the HST unit, it is maximum to be increased to output gradually by zero output, and the rotating speed of planetary gear train output shaft drops to zero gradually from maximum so.
Transmission process: 1, motor--HST unit (association of oil pump and oil hydraulic motor)--engine output shaft--driving gear----central gear---planetary pinion that outreaches gear;
2, motor--HST unit----HST unit output shaft--planet external toothing---planetary pinion;
Conclusion: when the HST of HST unit unit output shaft rotating speed when zero increases gradually; Because it is differential that the rotating speed of central gear and planet external toothing drives planetary pinion rotation generation, and the planetary pinion rotation is accelerated, the planetary pinion revolution is slowed down; This just makes planetary planetary wheel carrier rotating speed slow down; Output shaft and planetary wheel carrier are rigidly connected, thus output shaft slow down, until stopping; The output shaft rotating speed also is that planetary gear train is converted into infinite variable speed process by mechanical speed change from the highest process that reduces gradually.
The beneficial effect of the utility model is: the utility model is a kind of new device of double dynamical automatic conversion output of independent research, adopts planetary wheel carrier to rotate as power output, reaches the parallelly connected output with the oil hydraulic motor transmission of mechanical transmission; When making slow speed by the oil hydraulic motor transmission; Can realize stepless speed regulation stably,, simple in structure during the high-power output of high revolution by the transmission of motor direct mechanical; The high, low speed conversion steadily freely; The complete machine working efficiency can reach more than 85%, and energy conservation and consumption reduction effects very significantly reaches world-class levels.
