Description
Technical Field
The invention relates to a motor component, in particular to an internal tooth shell structure.
Background
Planetary gears are gear systems whose axes of rotation, in addition to being able to rotate about their own axis of rotation like a fixed axis gear, also rotate with the planet carrier about the axes of the other gears. Rotation about its own axis is called "rotation", and rotation about the other gear axis is called "revolution", just like a planet in the solar system, and hence its name. The planetary internal gear shell is a device for fixing a planetary internal gear, the rotation modes of the planetary internal gear are various, and the planetary internal gear shell is also designed to be matched with the rotation of the planetary internal gear to be different.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a precise planetary internal tooth shell structure which can adapt to complex internal tooth transmission, keep the stability of internal teeth in the internal tooth transmission process and reduce the noise generated in the transmission process.
In order to solve the technical problem, the precise planetary internal tooth shell structure comprises a base, an internal tooth shell is arranged on the base and is cylindrical, a placing cavity is formed in the internal tooth shell, an upper annular supporting wall is arranged in the placing cavity, an upper supporting surface is arranged at the top of the upper annular supporting wall, a lower annular supporting wall is arranged on the upper annular supporting wall, a lower supporting surface is arranged at the top of the lower annular supporting wall, a plurality of wedge-shaped grooves are uniformly formed in the upper supporting surface along the circumference, an annular rail is arranged on the lower supporting surface, and a plurality of movable balls are embedded in the annular rail.
Among the above-mentioned technical scheme, preferred, the even circumference in internal tooth casing top be provided with a plurality of first fixed orifices.
In the above technical solution, preferably, the four corners of the base are respectively provided with a second fixing hole.
In the above technical solution, preferably, the lower supporting surface is provided with an annular rail groove, the annular rail is embedded in the annular rail groove, and the annular rail is removable in the annular rail groove.
In the above technical scheme, preferably, the inner side wall of the placing cavity is attached with an annular elastic pad, and the bottom of the annular elastic pad is abutted against the upper supporting surface.
In the technical scheme, preferably, the lower supporting surface is provided with a plurality of oil leakage holes matched with the annular rail, oil filling holes are formed outside the inner tooth shell, and the oil filling holes are communicated with the oil leakage holes.
The invention relates to a precise planetary internal tooth transmission mechanism shell, which is provided with a complex transmission mechanism, wherein the shell for fixing the precise transmission mechanism needs to be precisely fixed with internal teeth, otherwise, vibration and noise are generated during movement, and once a certain part has vibration error, the precision of the whole system is greatly reduced. For this purpose, a precise fit is required between the internal toothing and each housing. The utility model provides a be provided with in the casing with the accurate fixed last holding surface of internal tooth, be provided with again and let the accurate pivoted under bracing face of internal tooth, through the different functions of two holding surfaces, can let the planet internal tooth keep fixed at the operation in-process, can not take place to influence the displacement of error, still reduced the noise simultaneously under the effect of annular cushion, increased fixed frictional force.
Compared with the prior art, the invention has the beneficial effects that: the internal gear transmission device can adapt to complex internal gear transmission, keep the stability of the internal gear in the internal gear transmission process and reduce noise generated in the transmission process.

Detailed Description
The present invention will be described in further detail with reference to specific embodiments.
Example 1: as shown in fig. 1-2, accurate planet internal tooth shell structure, including base 1, base 1 on be provided with internal tooth casing 2, internal tooth casing 2 be the cylinder type, internal tooth casing 2 in have and place chamber 3, place and be provided with annular support wall 21 in the chamber 3, last annular support wall 21 top be provided with up holding surface 41, last annular support wall 21 on be provided with down annular support wall 22, lower annular support wall 22 top be provided with down holding surface 51, last holding surface 41 on evenly be provided with a plurality of wedge type groove 42 along the circumference, down holding surface 51 on be provided with annular rail groove 52, annular rail 53 embedded annular rail groove 52 in, annular rail 53 be in annular rail groove 52 that can dismantle. A plurality of movable balls 54 are embedded in the circular track 53. The lower supporting surface 51 is provided with a plurality of oil leakage holes 55 matched with the annular rail 53, oil filling holes 23 are arranged outside the internal gear shell 2, and the oil filling holes 23 are communicated with the oil leakage holes 55. The top of the inner gear shell 2 is provided with a plurality of first fixing holes 9 on the uniform circumference. And B fixing holes 8 are respectively formed in four corners of the base 1. The inner side wall of the placing cavity 3 is attached with an annular elastic pad 7, and the bottom of the annular elastic pad 7 is propped against the upper supporting surface 41.
When the planetary internal tooth transmission mechanism is used, the planetary internal tooth transmission mechanism is placed in the placing cavity 3, the fixed part of the planetary internal tooth transmission mechanism is clamped on the wedge-shaped groove 42 of the upper supporting surface 41, and the rotating part is clamped on the annular track 53 on the lower supporting surface 51. Then through bolt and first fixed orifices 9, second fixed orifices 8 with whole casing fixed seal, the operation that planet internal tooth rotating part can be good during operation, fixed part can be firm fixed, the error that appears between big frequency long-time operation back planet internal tooth and internal tooth casing 2 is also very little, does not influence the precision of whole planet internal tooth operation.
