Description
Technical field
The utility model relates to a kind of motor component, especially a kind of internal tooth shell structure.
Background technique
Planetary gear refer in addition to can as fixed axis gear around oneself rotation axis rotation other than, their rotation
The gear train that axis is rotated also as planet carrier around the axis of other gears.Rotation around oneself axis is known as " rotation ", around it
The rotation of its Gear axis referred to as " is revolved ", just as the planet in the solar system, is hence obtained one's name.Planet internal tooth shell is fixed
The device of planet internal-gear, planet internal tooth rotating manner multiplicity, planet internal tooth shell also to cooperate the rotation of planet internal tooth into
The different design of row.
Utility model content
The utility model aiming at the shortcomings in the prior art, provides accurate planet internal tooth shell structure, can adapt to multiple
Miscellaneous internal tooth drive keeps the stabilization of internal tooth in internal tooth transmission process and reduces the noise generated in transmission.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals, accurate planet internal tooth
Shell structure, including pedestal are provided with internal tooth shell on the pedestal, and the internal tooth shell is in cylindrical type, and described is interior
There is placed cavity in tooth housing, annular support wall, setting at the top of the annular support wall are provided in the placed cavity
There is upper supporting surface, lower annular support wall, setting at the top of the lower annular support wall are provided in the upper annular support wall
There is bottom support surface, several wedge type grooves have been uniformly arranged along the circumference on the upper supporting surface, have been arranged on the bottom support surface
There is circular orbit, several moveable balls are embedded in the circular orbit.
In above-mentioned technical proposal, it is preferred that the internal tooth case top uniform circular is provided with several first fixation holes.
In above-mentioned technical proposal, it is preferred that the pedestal quadrangle is respectively arranged with second fixation hole.
In above-mentioned technical proposal, it is preferred that annular track slot is provided on the bottom support surface, in the circular orbit
In the annular track slot, the circular orbit is dismountable in the annular track slot.
In above-mentioned technical proposal, it is preferred that the placement chamber inner sidewall is fitted with cyclic spring pad, the shape elasticity
Upper supporting surface described in rebasing portion landlord.
In above-mentioned technical proposal, it is preferred that be provided with several on the bottom support surface and the circular orbit matches
Oil leaking hole is closed, the inner tooth shell is provided with oil filler point in vitro, and the oil filler point is connected to the oil leaking hole.
The utility model is a kind of shell of the planet internal tooth drive mechanism of precision, for accurate planet internal tooth drive machine
For structure, there is complicated transmission mechanism, the shell for fixing them needs to accomplish accurate fixation between internal tooth, no
Vibration and noise can be then generated during exercise, the precision of whole system will be made to beat greatly once vibration error occurs in some component
Discount.It thus will precision-fit between internal tooth and each shell.It is provided in the shell of the application and the fixation of internal tooth precision
Upper supporting surface, and be provided with and can allow the bottom support surface of internal tooth precise rotation can allow planet by the different role of two supporting surfaces
Internal tooth is kept fixed during operation, will not influence the displacement of error, while also under the action of cyclic spring pad
Reduce noise, increases fixed friction power.
Compared with prior art, the utility model has the beneficial effects that can adapt to complicated internal tooth drive, passed in internal tooth
The stabilization of internal tooth is kept during dynamic and reduces the noise generated in transmission.
