Description
Technical field
The utility model relates to a kind of torque amplification, the torque amplification that especially a kind of enclosed exports, and belongs to technical field of hydraulic pressure.
Background technique
Torque amplification is the less moment of torsion of a kind of input and obtains the hydraulic element of larger output torque.Primarily of valve body, valve core housing, turn the composition such as stator, output shaft, its basic structure and working principle can be the Chinese patent literature of 201110073070.6 see application number.After supporting with the agricultural hitching machinery of rice transplanter and so on, when not steering wheel rotation, oil flows through valve core housing and directly flows back to fuel tank.When steering wheel rotation, oil stream is entered by valve core housing and turns stator, hydraulic energy (pressure, flow) is converted to mechanical energy (moment of torsion, rotating speed) to export, output speed is identical with the rotating speed of steering wheel, output torque is manual input torque and the summation turning stator output torque, therefore there is moment of torsion amplification, be widely used in farm machinery steering system.
But according to the applicant understood, the torque amplification of prior art is not owing to having adaptive external link structure, therefore be connected with the speed changer of various agricultural machinery, need separately to join a transition interfacing orchid as one sees fit, it is too fat to move that result not only result in structure, and add leakage link.In addition, the fuel tank of prior art torque amplification and the fuel tank of gearbox are separated from each other, make the structure of steering system not compact, install inconvenient, and add cost, cause waste.
Summary of the invention
The purpose of this utility model is: for above-mentioned prior art Problems existing, by architecture advances, proposes the torque amplification of a kind of compact structure, easy for installation, good seal.
In order to reach above object, torque amplification of the present utility model comprises the housing be fixedly connected with according to the order of sequence, front every dish, stator, after every dish, described housing have filler opening and oil outlet and valve core housing is equipped with in inside, described stator is built with rotor, described rotor inner hole is connected with a joggle with the opposite end exporting couple axle with input couple axle simultaneously, front end and the valve core housing of described input couple axle are in transmission connection, the rear end of described output couple axle stretch out after every the center hole of dish, its improvements are, also comprise the external flange having and export couple axle perforation, described external flange have with after every dish, stator, the front countersunk head perforation corresponding every dish position, penetrate the inner in the perforation of described countersunk head and be screwed in countersunk head clamping bolt in housing tapped hole.
After adopting the utility model, not only without the need to separately joining transition piece, can be connected with agricultural machinery gearbox easily, and structure of the present utility model is conducive to solving sealing problem when connecting, therefore compact structure, easy for installation, favorable sealing property.
Further, the disk body of described external flange extends the installation with mounting hole respectively towards radial two ends protruding, and the cylinder table assigning hole to match with gearbox is axially extended in the exterior edge face of described disk body, and described countersunk head perforation is positioned at the end face of described cylinder table.Like this, external flange with after every coiling, stator, to be frontly all included in cylinder table every coiling all countersunk head clamping bolts be connected, as long as handle the sealing of external flange exterior edge face and cylinder table and gearbox well, namely block the channel that leaks of all countersunk head clamping bolt joints, therefore solve leakage problem easily.
Further, during external gearbox, the fuel tank of described gearbox by connecing the filler opening of described torque amplification housing through the transport pipe of oil pump, thus makes torque amplification and gearbox share fuel tank, makes compact structure further, installs more convenient, minimizing leakage link.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The sectional view of Fig. 1 the utility model embodiment.
Fig. 2 is the external flange structural representation of Fig. 1 embodiment.
Fig. 3 is the sectional view of Fig. 2.
Fig. 4 is Fig. 1 embodiment using state schematic diagram.
Embodiment
Torque amplification of the present utility model as shown in Figure 1, comprise be fixedly connected with according to the order of sequence housing 1, front every dish 6, stator 7, after every dish 8.Housing 2 is built with valve core housing 2, stator 7 is built with the rotor 3 with its formation cycloidal pin wheel set, the endoporus of rotor 3 is connected with a joggle with the opposite end exporting couple axle 4 with input couple axle 9 simultaneously, the front end of input couple axle 9 is in transmission connection by finger 10 and valve core housing 2, the rear end exporting couple axle 5 stretch out after every dish 8 center hole and near after the output couple axle perforation at external flange 5 center outside dish 8.
The concrete structure of external flange 5 as shown in Figures 2 and 3, its disk body 5-1 extends the protruding 5-3 of the installation with mounting hole 5-2 respectively towards radial two ends, the cylinder table 5-4 assigning hole to match with gearbox is axially extended in the exterior edge face of disk body 5-1, cylinder table 5-4 end face border have with after to bore a hole 5-5 every dish 8, stator 7, the front countersunk head corresponding every dish 6 position, penetrate the inner in countersunk head perforation 5-5 and be screwed in countersunk head clamping bolt 5-6 in housing 1 tapped hole.
During external gearbox, as shown in Figure 4, what directly matched by the cylinder table of external flange 5 insertion gearbox 12 assigns in hole, fix with the fastening piece through mounting boss position, very convenient, due to external flange with after every coiling, stator, to be frontly all included in cylinder table, as long as therefore handle the sealing of external flange both ends of the surface and abutment well by end-face seal ring 11 every coiling all countersunk head clamping bolts be connected, namely the sealing problem of all joints has been properly settled, very convenient.In addition, the fuel tank of gearbox 12 by connecing the filler opening of torque amplification housing 1 through the transport pipe of oil pump 13, thus makes torque amplification and gearbox share fuel tank, make further compact structure, easy for installation, decrease leakage link.
During work, when not steering wheel rotation 30, fluid directly flows back to fuel tank after flowing through the valve core housing of torque amplification.When steering wheel rotation 30, fluid is entered by valve core housing and turns stator, hydraulic energy (pressure, flow) is converted to mechanical energy (moment of torsion, rotating speed) to export, output speed is identical with steering wheel rotating speed, moment of torsion is manual input torque and turn the moment of stator output torque summation, thus to there is moment of torsion amplification and order about agricultural running mechanism realize needed for course changing control.Another advantage of the present embodiment is, if damage cannot fuel feeding for oil pump 13, torque amplification as mechanical steering gear, will export the moment of not amplifying, play the manipulation effect of manual steering.
