The technical solution of the utility model is as follows:
A kind of planet differential braking device, it comprises the differential planetary speed-change gear box, be used on the retarder that hoists, same motor, reel and planetary gear train are connected, each is connected two ends of the inner input shaft of described differential planetary speed-change gear box with a cover planetary gear train, and planet carrier, the sun gear of two cover planetary gear train are connected by axle, and the output shaft of each planet carrier is connected with the intergrade gear pair, connect the slow speed turbine stage gear pair again, connect two reels that are positioned at two sides by output shaft then; Described motor is provided with two, is connected with the sun gear of planetary gear train respectively, and installing differential braking device between the main shaft of every cover planetary gear train and motor shaft, the external toothing of every cover planetary gear train then links with the differential braking device.
Planet differential braking device of the present utility model is exactly the retarder that hoists that is used for container crane, realize the output of retarder different modes, realize and can hoist synchronously by two 40 forty equivalent unit 40s guaranteeing, again can single 40 forty equivalent unit 40s or 45 forty equivalent unit 40s hoist separately.
The utility model adopts a differential or pan of a steelyard formula break, utilize the closed of electromechanical integration control brake device or open, the one degree of freedom of restriction or release planetary gear train, control the outbound course of power and the distribution of torque quickly and easily, thereby make hoist two 40 forty equivalent unit 40s of can slinging hoist synchronously, descend, again can be with the independent suspender of all torsion torque, the operation that hoists at a high speed, descends of sling separately single 40 forty equivalent unit 40s or 45 forty equivalent unit 40s, realized following operating mode:
1, one or two motor inputs;
2, whole output shafts output torques simultaneously, but also half output shaft output torque;
3, two power input to machines can be dispensed to whole output shafts automatically according to outer difference of carrying;
4, two power of motor can be synthesized and output to certain half output shaft, realize single suspender operation.
Description of drawings
Accompanying drawing is the structural representation of a kind of planet differential braking device of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of planet differential braking device of the present utility model is used to the retarder that hoists, and it is gearbox that this device is equipped with differential planetary speed-change gear box 1, and same motor, reel and planetary gear train are connected.
Each is connected two ends of differential planetary speed-change gear box 1 inner input shaft with a cover planetary gear train 2.Every cover planetary gear train 2 is made up of planet carrier 21, sun gear 22, planetary pinion 23, interior external toothing 24 4 big component, and the planet carrier 21, sun gear of two cover planetary gear train 2 22 are connected by axle.The output shaft of each planet carrier 21 is connected with intergrade gear pair 3, connects slow speed turbine stage gear pair 4 again, connects two reels that are positioned at two sides by output shaft 5 then.
Reel has four, and they are separately positioned on two ends of the output shaft 5 of two slow speed turbine stage gear pairs 4, i.e. a cover planetary gear train 2 final two reels 7, other two reels 8 of another set of planetary gear train 2 final connections of connecting.
Motor 6 is set to two, is connected with the sun gear 22 of planetary gear train 2 respectively.Power of motor exports intergrade gear pair 3, slow speed turbine stage gear pair 4, output shaft 5 outputs to by sun gear 22 inputs, the planet carrier 21 of planetary gear train 2 successively.
Two cover planetary gear train 2 are the planetary mechanisms with two degrees of freedom, and when one of them degrees of freedom was limited, power just can be exported from the transmission of another one degrees of freedom; When two degrees of freedom all are released, this moment, power can't be exported.
Installing differential braking device 9 between the main shaft of every cover planetary gear train 2 and motor shaft, the external toothing of every cover planetary gear train 2 then links with differential braking device 9.According to the different operating combination of motor 6 and differential braking device 9, by changing the mode of the degrees of freedom that limits planetary mechanism, two input motions are carried out different distribution, output is gone again, thereby realizes each output shaft output different rotating speeds.Adopt planet differential braking device of the present utility model, the moment of torsion that hoists synchronously and needed separately of both practicable two cover suspenders, an also practicable cover operation operating mode that suspender hoists, another set of suspender is motionless.
According to the utility model, by closed or open the differential braking device, restriction or discharge the one degree of freedom of planetary gear train with the outbound course of control power, thereby realizes powershift.Working state by control differential braking device, change or limit the mode of the degrees of freedom of planetary mechanism, make the differential planetary speed-change gear box realize each output shaft output different rotating speeds, turn to and moment of torsion,, realize two planetary mechanisms or the more combination of multirow star mechanism by this class gearbox.
When needs originally install all when exporting all output torque, when promptly two cover suspenders hoisted operation simultaneously, gearbox can be realized the decomposition of power, and it can distribute to whole output shafts with the output power of motor, realizes two cover suspender operations.Its groundwork characteristics are: brake simultaneously with two differential braking devices that the external toothing of planetary gear train links, the gear ring that is equivalent to two cover planetary gear train of gearbox inside this moment is fixed, power input to a machine is distributed to four reels after by the output of sun gear input planet carrier, makes two reels 7 and two reels 8 obtain the moment of torsion of same rotating speed, different needs.
When needs originally install an end output torque (two reels 7 as shown in FIG.), and the other end is not during output torque (two reels 8 as shown in FIG.), when promptly needing a cover suspender to hoist operation separately, gearbox can be realized the stack of power, it can be superimposed the output power of motor, be defeated by one group of output shaft (two reels 7 as shown in FIG.), realize a cover suspender operation.Only so, just can make hoist when using a cover suspender, realize high-speed and high-efficiency.Otherwise, also can.Its groundwork characteristics are: a differential braking device braking that will link with the external toothing of planetary gear train, another differential braking device is opened, and then with the braking of two reels (two reels 8 as shown in FIG.) break of a corresponding side, the planet carrier that is equivalent to a cover planetary gear train of gearbox inside this moment is fixed, the gear ring freedom, and the gear ring of another set of planetary gear train is fixed, power input to a machine stacks up by only driving a reel (reel 7 as shown in FIG.) after revocable planet carrier output by planetary mechanism, make the suspender work that interrelates with it, realize overweight high speed operation.Otherwise, as the same.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim variation, the modification of the foregoing description.
