Abstract
The utility model belongs to sliding-vane motor field, relate to a kind of axial locking device designing technique for sliding-vane motor, the present invention is by providing a kind of axial locking device of rotor, in sliding-vane motor high speed motions, the rotor axial play that elimination may occur, avoids the generation of the problem such as vibration, part injury caused because of rotor axial play in traditional blades motor.
Description
Technical field
The utility model belongs to sliding-vane motor field, relates to a kind of axial locking device for sliding-vane motor rotor.
Background technique
In traditional sliding-vane motor, its rotor one end is connected with housing by bearing, the other end then adopts cantilever type to support, in sliding-vane motor high speed motions, rotor inevitably produces axial float, and cause product to vibrate, part clashes into mutually, thus cause the part injuries such as rotor, greatly reduce operating life and the reliability of sliding-vane motor.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of axial locking device for sliding-vane motor rotor, improves reliability and the life-span of oil hydraulic motor.
For the technical solutions of the utility model that solve the problem provide a kind of axial locking device for sliding-vane motor, comprise locking nut 1, locked spacer 2, wedge 3, pad 4, bearing 5, minipad 6, rotor 7, cover plate 8, it is characterized in that, described rotor 7 is equipped with bearing 5, bearing 5 outer shroud and wedge 3 closely cooperate and to play a supportive role to described rotor 7, rotor 7 is in cylinder table scalariform, screw thread is being processed with by cylndrical surface, end, and a groove, described locked spacer 2 is sleeved on side on rotor 7 and compresses bearing 5, internal tooth is embedded in the groove of rotor 7, described locking nut 1 installs on rotor 7 with the screw-thread fit cover of cylndrical surface, rotor 7 end, described locking nut 1 outer rim has keyway, the external tooth of described locked spacer 2 is embedded in the groove of locking nut 1.
Preferably, rotor 7 can be rectangle by the shape of groove on cylndrical surface, end, also can be U-shaped.
Preferably, the keyway of locking nut 1 can be 2 ~ 8, and it can be parallel bottom two, also simultaneously can have chamfering.
The beneficial effects of the utility model: the utility model is used for the rotor of sliding-vane motor, a kind of axial locking device is adopted to be fixed by rotor axial, avoid in sliding-vane motor high speed motions, the axial float of rotor, and the product caused vibrates, part clashes into mutually equivalent damage problem, effectively improve operating life and the reliability of sliding-vane motor, be applicable in hydraulic pressure, mechanical field the life-span of sliding-vane motor and the higher industry of reliability requirement.

Wherein, 1-locking nut, 2-locked spacer, 3-wedge, 4-pad, 5-bearing, 6-minipad, 7-rotor, 8-cover plate.
Embodiment
For better the utility model being described, illustrate below in conjunction with accompanying drawing.
Refer to accompanying drawing 1, a kind of axial locking device for sliding-vane motor, comprise locking nut 1, locked spacer 2, wedge 3, pad 4, bearing 5, minipad 6, rotor 7, cover plate 8, it is characterized in that, described rotor 7 is equipped with bearing 5, bearing 5 outer shroud, pad 4 and wedge 3, cover plate 8 closely cooperates and to play a supportive role to described rotor 7, bearing 5 inner ring is combined closely by minipad 6 and described rotor 7, rotor 7 is in cylinder table scalariform, screw thread is being processed with by cylndrical surface, end, and a groove, described locked spacer 2 is sleeved on side on rotor 7 and compresses bearing 5, internal tooth is embedded in the groove of rotor 7, described locking nut 1 installs on rotor 7 with the screw-thread fit cover of cylndrical surface, rotor 7 end, described locking nut 1 outer rim has keyway, the external tooth of described locked spacer 2 is embedded in the groove of locking nut 1.
Preferably, rotor 7 can be rectangle by the shape of groove on cylndrical surface, end, also can be U-shaped.
Preferably, the keyway of locking nut 1 can be 2 ~ 8, and it can be parallel bottom two, also simultaneously can have chamfering.
Sliding-vane motor is in high-speed rotation, and rotor 7 easily produces axial float, causes the damage of bearing 5, cover plate 8, and adopt the axial locking device of rotor 7 by rotor 7 axially locating, locking, avoid rotor 7 axial float, bearing 5, cover plate 8 are protected.
Refer to accompanying drawing 2, accompanying drawing 3, locked spacer 2 is contained on the step of rotor 7, locking nut 1 pushes down locked spacer 2, be screwed on the screw thread of rotor 7, the internal tooth of locked spacer 2 is embedded in the rectangle groove of rotor 7, and its external tooth is embedded in the groove of locking nut 1, and rotor 7, locking nut 1 and locked spacer 2 are connected, thus fixing, spacing for rotor 7, finally alleviate the wearing and tearing of part, the operating life improving sliding-vane motor and reliability.
