Oil hydraulic motor is made the hydraulic actuator of continuous rotary motion and output torque.Oil hydraulic motor refers to traditionally to export and rotatablely moves, and the hydraulic energy that oil hydraulic pump is provided changes the energy conversion device of mechanical energy into.Oil hydraulic motor also is called oil motor, is mainly used in injection machine, boats and ships, rises and raise machine, engineering machinery, building machinery, coal mine machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, harbour machinery etc.Oil hydraulic motor has the final stage planet carrier, this planet carrier comprises support body, axial centre is provided with center hole, and there is following defective in existing these planet carriers: structure is complicated, is difficult for making, manufacturing efficiency is lower, in addition, the structural strength of this flange is lower, that is to say that non-deformability is relatively poor, working life is short, has virtually increased user cost.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of hoist cylinder actuating device [application number: 200620027262.8], comprise that left and right sidesing supporting frame is equipped with cylindrical shell by bearing, a side is installed connecting sleeve in the cylindrical shell, the other end of connecting sleeve is installed two ring gears and end cap by the convex shoulder connecting sleeve, oil hydraulic motor and the hydraulic brake coaxial with cylindrical shell are installed on the supporting frame, the sun gear of mounting strap axostylus axostyle on end cap the inner and hydraulic motor output shaft, intermeshing planet wheel and planet carrier thereof are installed between sun gear and the ring gear, at the shaft rod upper sleeve of sun gear sun gear with the planet carrier spline coupling is housed, intermeshing planet wheel and planet carrier thereof are installed between sun gear and ring gear, on the axostylus axostyle of sun gear, also are set with the spline housing with planet carrier and supporting frame spline coupling.Above-mentioned scheme has been improved prior art to a certain extent, but at least also there is following defective in this scheme: the structure of flange is complicated, so not only reduced manufacturing efficiency, and processing cost is also higher, and in addition, its structural strength is low, and working life is short.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of simple in structure, is easy to make the final stage planet carrier that be applicable to oil hydraulic motor high with structural strength.
For achieving the above object, the utility model has adopted following technical proposal: the final stage planet carrier that originally is applicable to oil hydraulic motor comprises support body in the form of annular discs, be provided with center hole and some through holes that is arranged on the center hole periphery in the support body axial centre, it is characterized in that, be provided with the ring-shaped step and the annular boss that lay respectively at its place, aperture, two ends in the described center hole, be provided with internal spline and the annular slot to make way that is arranged on this internal spline the inner at ring-shaped step.Obviously, the utility model design is more reasonable, simple in structure and easy manufacturing, and easily installation and removal, and in addition, structural strength is very high, and working life is longer, can reduce user cost.
In the above-mentioned final stage planet carrier that is applicable to oil hydraulic motor, the described support body outside be provided with some respectively with described through hole screw corresponding and that be communicated with through hole one by one.
In the above-mentioned final stage planet carrier that is applicable to oil hydraulic motor, described support body is provided with counterbore near an end of internal spline, and described counter bore hole diameters is greater than described inner spline gear Root diameter.
In the above-mentioned final stage planet carrier that is applicable to oil hydraulic motor, described support body is included in the first subrack and the second subrack, and the connecting tendon that distributes by some even circumferentials between described the first subrack and the second subrack is connected.
Compared with prior art, the advantage that originally is applicable to the final stage planet carrier of oil hydraulic motor is: it is more reasonable to design, simple in structure and easy manufacturing, and easily installation and removal, and in addition, structural strength is very high, and working life is longer, can reduce user cost.
