One end reach the other end, carry out the special installation by motor mesopore such as arrangement brake device, velometer, general standard motor is difficult
To realize the these requirements of user.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of hydraulic motor with inner curved piston through hole device, with using
Scope is wide, facilitates client to be configured according to demand to motor, greatly simplify requirement of the user to main machine structure, greatly facilitates
The design of system, the features such as cost-effective.
The utility model solves the technical scheme that its technical problem used：A kind of hydraulic motor with inner curved piston through hole is provided
Device, including ring-type rear end cap and rotor rear end cap, the lower end of described rotor rear end cap are inserted into the inner ring of ring-type rear end cap
It is interior, it is disposed with circular hollow in the middle part of described rotor rear end cap, insertion is provided with the second O-ring on circular hollow side wall, described
Rotor rear end cap upper surface be arranged symmetrically two oilholes close to circular hollow place, two oilhole lower ends pass through runner with it is circular
Hollow lower sidewall connection.
The annular groove that a circle matches with rotor rear end cap top, rotor are disposed with the middle part of described ring-type rear end cap upper surface
V-type dust ring is installed between rear end cap outer ring and annular groove.
Described ring-type rear end cap upper surface is disposed with a circle inserting groove at annular groove, and described rotor rear end cap is leaned on
The annular grafting matched with inserting groove is disposed with the lower surface of nearly outer ring raised.
It is embedded in the middle part of described rotor rear end cap lower surface that the first O-ring is installed.
The device sealing dust-proof device meets demand of the motor in particular application, extends hydraulic motor with inner curved piston
Application field, by using the device, realize the structure of motor mesopore, facilitate user to configure various special set as requested
It is standby, by using the device, requirement of the user to main machine structure can be greatly simplified, the design of system is greatly facilitated, saved
About cost.
The end cap central of script does not arrange through hole, and the main shaft of hydraulic motor can not stretch out at rear end cap, this structure
So that, other optional equipments, which need with the main shaft of hydraulic motor to be connected with more parts, considerably increases installation cost, increase
Installation difficulty.
Beneficial effect：The utility model is related to a kind of hydraulic motor with inner curved piston through hole device, with use scope extensively, conveniently
Client is configured to motor, greatly simplifies requirement of the user to main machine structure according to demand, greatly facilitates setting for system
Meter, the features such as cost-effective.
