A body shell of the axial allocation cycloid hydraulic motor is of an integral structure, a casting hole channel is formed in the body shell and communicated with a check valve structure, and a check valve is isolated from the outside through an end cap and sealed through a single O-shaped ring. Due to the improvement, the structure of the check valve is simplified and the sealing reliability of a check valve body is improved; and since one end, located at an oil port face, of the body shell is arranged to be in a right-angle shape, an inclined oil port or an oil port perpendicular to the axial direction can be machined in the oil port face, and a plug-in overflow valve can be installed.
Description
Technical field
The present invention relates to a kind of oil motor, especially a kind of integral type flange axle distributing cycloid hydraulic motor, belongs to hydraulic transmission technology field.
Background technology
Cycloid hydraulic motor is conventional fluid pressure drive device, is also realize the conventional hydraulic pressure execution device that hydraulic pressure can convert function to. Cycloid hydraulic motor is a kind of low-speed big torque motor, has the advantages such as volume is little, unit power density big, efficiency height, speed range width, is thus widely applied.
The flow-distribution mechanism of axle distributing cycloid hydraulic motor is positioned at the radial distribution different quantities flow duct of the pintle of the output shaft cooperatively interacted and the assignment hole of body shell, during motor operations, flow-distribution mechanism makes fluid inlet engage chamber connection with the expansion of cycloidal pin wheel set, and the contraction chamber making cycloidal pin wheel set is connected with refluxing opening. As a result, after pressure fluid enters body shell or bonnet from fluid inlet, entering the expansion engagement chamber that cycloidal pinion engaged pair is formed so that it is volume constantly expands, in the contraction engagement chamber that cycloidal pinion engaged pair is formed simultaneously, liquid then refluxes from refluxing opening; In the process, the rotor of cycloidal pinion engaged pair be expanded engagement chamber with shrinking pressure difference engage chamber order about rotation, and this is rotated through the axle that links and is delivered to output shaft output, thus realize hydraulic pressure can to the conversion of mechanical energy. Meanwhile, flow-distribution mechanism (axle valve) is also by linkage axle driven rotary, and the continuous switching connected state gone round and begun again, makes switching process be continued. Like this, motor just can continuous print output torque.
According to the applicant understood, the check valve of existing axle distributing cycloid hydraulic motor is arranged at the one end installing only mouth usually, it is arranged between protecgulum and body shell, screw is adopted to be fastened on by protecgulum on body shell, check valve adopts valve body, 2 sealing-rings, valve ball compositions usually, or increase elastomerics and valve ball composition one, as shown in " CN201120554913.X axle flow-distribution cycloid hydraulic motor for rear shaft output " utility model patent. But it is the molectron adopting screw to be connected between the body shell of this structure and protecgulum, tolerance on fit between mating surface and each finish size of increase and form and position tolerance thereof, all can affect the connection precision of motor, need the requirement that the precision improving each cooperation and size and morpheme reaches theoretical, cost can be increased and reduce production efficiency, especially existing one-way valve structures, what adopt is the oil through having an oblique leakage fluid between the open holes between 2 O, easily cut circle during installation, O RunddichtringO sealing effect can be affected.
Summary of the invention
The object of the invention is: the deficiency existed for above prior art, it is proposed to a kind of novel one-way valve structures motor, and this structure is monoblock type body shell, installs only mouth and mounting flange set and is integrated, and this structure is applicable to monoblock type and edge pillar cycloid turns stator pair.
In order to achieve the above object, applicant is by the analysis of Integral Structure to axle distributing cycloid hydraulic motor, especially flow-distribution mechanism, the relation of You Kou position and check valve passage and installation position and characteristic, the technical scheme proposing following the present invention is: a kind of integral type flange axle distributing cycloid hydraulic motor mainly comprise output shaft, body shell, linkage axle, every dish, turn stator pinwheel secondary, bonnet etc., stator be jointly fixed on body shell every dish and bonnet by bolt, described body shell adopts one-piece construction, its improvements are, in described body shell, there is casting duct, described casting duct is connected with one-way valve structures, described check valve is by valve body, valve ball and sealing-ring composition, valve ball is arranged at the inner chamber of valve body, one end of described inner chamber is communicated with casting duct by aperture, the other end is by 3 extruding spacing valve balls of distortion, described one-way valve structures has the sealing of single sealing-ring.
Described check valve is resisted against that to carry out spacing, described stifled head on stifled head be that ball rises formula high-pressure drain plug.
The casting duct that described body shell has is arranged at front end, and described casting duct is local one-way channel, and skew is arranged at one end of oil actinal surface.
Described casting duct is linked up by the oil passage in output shaft and check valve as the Leakage Energy of motor.
Further perfect of above technical scheme: square is arranged in the oily actinal surface one end on described body shell, oil actinal surface arranges the boss that two are installed screws.
Compared with the axle distributing cycloid motor of prior art, the such scheme of the present invention well eliminates the oblique pore structure of existing check valve oil duct, simplify the structure of check valve, improve the sealing reliability of check valve body, oil actinal surface can process the oily mouth of oblique oil mouth or vertical axial, and installs plug-in overflow valve.
