And user need not again be processed and buy some installation annexes etc., and difficulty and cost are used so as to reduce user, it is ensured that
System is more reliable and more stable.
The technical solution of the utility model is：
A kind of square petroleum machinery bearing-free cycloid hydraulic motor, including adpting flange, stator-rotator pair, linkage output shaft,
Valve disc, back casing, oil distribution casing, it is characterised in that described back casing is fixedly connected with valve disc, and valve disc is connected with stator-rotator pair,
Stator-rotator pair is fixedly connected with adpting flange；Described back casing, valve disc, stator-rotator pair and adpting flange are exported with linkage
The vertical section of axle axis is square；Stud is provided with back casing rear end.
The characteristics of the utility model, also has：
Studs is provided with back casing rear end, client's special mounting demand is met.

Specific embodiment
For the technical characterstic for illustrating this programme can be understood, below by a specific embodiment, and it is combined
Accompanying drawing, is illustrated to this programme.
A kind of square petroleum machinery bearing-free cycloid hydraulic motor, including adpting flange 2, stator-rotator pair 3, linkage output shaft
1st, valve disc 4, back casing 5, oil distribution casing 6, described back casing 5 are fixedly connected with valve disc 4, and valve disc 4 is connected with stator-rotator pair 3, fixed
Rotor secondary 3 is fixedly connected with adpting flange 2；Described back casing 5, valve disc 4, stator-rotator pair 3 and adpting flange 2 with linkage
The vertical section of the axis of output shaft 1 is equalFor square；Stud 7 is provided with the rear end of back casing 5.
Stud is provided with the rear end of back casing 5, client's special mounting demand is met.
Described square petroleum machinery bearing-free cycloid hydraulic motor is exclusively used in the connection of petroleum machinery coordinative composition of equipments.
Also include the small universal driving shaft 8 coordinated with stator-rotator pair 3, described small universal driving shaft 8 is connected with oil distribution casing 6.
Described linkage output shaft be used for the supporting connection of deep groove ball bearing, load capacity is big.
Specific works mode is that, because petroleum machinery is to the particular/special requirement in space, profile meets installation requirements, by connection
Flange upper bolt hole is fixed with the stud of rear end, using the zanjon that load capacity is larger when supporting output shaft is connected with motor
Ball bearing, flange coordinates skeleton oil seal when connecting, inner volume forms confined space, and the fluid inside let out passes through built-in emptying
Passage enters fuel tank through unloading port, do not result in internal back pressure it is too high so as to influence motor life and efficiency the problems such as, motor sheet
Body is not related to bearing, largely reduces axial dimension, saves space, simplifies structure.
The utility model designs a kind of square petroleum machinery bearing-free cycloid hydraulic motor structure, in original cycloid hydraulic pressure horse
On the basis of reaching, external motors structure and connection pattern are changed, it is special that rational deployment motor configuration and size for connection meet petroleum machinery
Determine operating mode installation requirement, accomplish to meet client using the studs connected mode installed, axial dimension and radial dimension pressure
Minimum is reduced to, the small-sized bearingless motors that the small space connection of petroleum machinery Special square is used are realized.
Technical characteristic of the utility model without description can be achieved by the prior art, and will not be repeated here.Certainly, on
It is not that, to limitation of the present utility model, the utility model is also not limited to the example above to state bright, the art it is general
Change, remodeling, addition or replacement that logical technical staff is made in essential scope of the present utility model, should also belong to this practicality
New protection domain.
