Abstract
The invention discloses a multifunctional internal gear. The multifunctional internal gear comprises a gear body, wherein external teeth and internal teeth are arranged on the gear body; a central shaft hole is formed in the center of the gear body; a plurality of shaft installing holes are formed at the periphery of the central shaft hole; a plurality of positioning holes are formed in the gear body; fasteners are arranged on the positioning holes; a demountable gear cover plate is arranged on the gear body; and the gear cover plate is connected with the gear body through the fasteners. Therefore, the bearing capacity of the gear can be improved, vibration and noise are reduced and the service life of the gear is prolonged.
Description
Technical field
The present invention relates to the gear product technical field, particularly relate to a kind of multifunctional gear.
Background technique
The planetary pinion transmission is compared with the ordinary gear transmission; Have that volume is little, quality is little, compact structure, bearing capacity is big, transmission efficiency is high and velocity ratio is bigger advantage; Simultaneously, planetary pinion can carry out power dividing when transferring power, and its input shaft and output shaft have alignment.Therefore, the planetary pinion transmission is used to replace the ordinary gear transmission, and as the retarder in the various machine driven systems, speed increaser and speed change gear; Especially the gear drive that cube is little, quality is little for wanting, compact structure and transmission efficiency are high and need to be widely used especially in the gear drive of differential mechanism.The inside engaged gear transmission is planetary necessary engagement system, and one of planetary pinion transmission key technology is the especially precision machining of internal gear of gear.And along with the high speed development of science and technology, for the standardization of internal gear, the hard flank of tooth, high-precision require increasingly high.In the existing technology; Because the restriction in space; Methods such as internal gear processing is usually adopted gear shaping, drawn tooth, moulding are difficult to realize the highi degree of accuracy and the hard flank of tooth cause interior engagement driving (mainly being Gear Planet Transmission) vibration, noise, additional dynamic load etc.; Reduced its bearing capacity, life-span and reliability, therefore big limitations planetary development and application.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of reasonable in design, simple in structure, using scope is extensive, cost of production is low multi-functional internal gear, can improve bearing capacity, reduces vibration and noise, increases the service life.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of multi-functional internal gear is provided, comprises the gear body, said gear body is provided with outer teeth and interior teeth; Said gear body center is provided with central shaft hole; Said central shaft hole periphery is provided with a plurality of installation axle hole, and said gear body is provided with a plurality of positioning holes, cooperates on the said positioning hole fastening piece is installed; Also be provided with dismountable gear cover plate on the said gear body, said gear cover plate is connected with the gear body through fastening piece.。
In preferred embodiment of the present invention, the diameter of said installation axle hole is less than the diameter of central shaft hole.
In preferred embodiment of the present invention, said a plurality of installation axle hole are circular distribution, and the center of circle of said annulus overlaps with the center of installation axle hole.
In preferred embodiment of the present invention, said gear body is cylindrical.
In preferred embodiment of the present invention, be connected with small gear on the said installation axle hole.
The invention has the beneficial effects as follows: the multi-functional internal gear of the present invention is reasonable in design, simple in structure, using scope is extensive, cost of production is low, can improve bearing capacity, reduces vibration and noise, increases the service life.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, a kind of multi-functional internal gear comprises gear body 1; Said gear body 1 is provided with outer teeth 2 and interior teeth 3, and said gear body 1 center is provided with central shaft hole 4, and said central shaft hole 4 peripheries are provided with a plurality of installation axle hole 5; Said gear body 1 is provided with a plurality of positioning holes 6, cooperates on the said positioning hole 6 fastening piece 7 is installed, and also is provided with dismountable gear cover plate 8 on the said gear body 1; Said gear cover plate 8 is connected with gear body 1 through fastening piece 7, after gear cover plate 8 is installed, can be used as common gear and uses; After the disengage gear cover plate 8, can be used as internal gear and use.
In addition, the diameter of said installation axle hole 5 is less than the diameter of central shaft hole 4.
In addition, said a plurality of installation axle hole 5 are circular distribution, and the center of circle of said annulus overlaps with the center of installation axle hole 4.
In addition, said interior teeth 3 have nickeling layer with outer teeth 2 surface coverage, and nickeling layer can be antirust, greatly protected gear.
In addition, said gear body 1 is cylindrical.
In addition, be connected with small gear 9 on the said installation axle hole 5, the small gear of selecting to be fit to according to the needs that use 9 attaches it to use on the installation axle hole 5.
After the multi-functional internal gear of the present invention is installed gear cover plate 8; Can be used as common gear uses; After the disengage gear cover plate 8, can be used as internal gear and use, the small gear of selecting to be fit to according to the needs that use 9 attaches it to use on the installation axle hole 5.
Be different from existing technology, the multi-functional internal gear of the present invention is reasonable in design, simple in structure, using scope is extensive, cost of production is low, can improve bearing capacity, reduces vibration and noise, increases the service life.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
