Technical field
The present invention relates to a kind of gear, particularly relate to one and can carry out pinpoint gear.
Background technology
Gear is generally as acceleration or deceleration effect, existing gear generally all includes central gear, bracket, rim gear wheel and planetary gear, but the engagement place of planetary gear and central gear and rim gear wheel can produce back clearance, existence due to this back clearance, can produce cannot be correct control in conjunction with the output link in epicyclic gear mechanism, or be provided with the problem of the position of rotation of epicyclic gear mechanism arrangement, thus causing that output link cannot position accurately.
Therefore those skilled in the art be devoted to exploitation one can carry out pinpoint gear structure.
Summary of the invention
Because the drawbacks described above of prior art, those skilled in the art are devoted to exploitation one can carry out pinpoint gear structure.
The technical problem to be solved is to provide a kind of new gear structure, including central gear, rim gear wheel and support body, central gear is set on power shaft, described rim gear wheel is set on described output shaft, is provided with first planet gear, the second planetary gear, third planet gear and fourth planet gear between central gear and rim gear wheel; The module of first planet gear is 4;
First planet gear, the second planetary gear, third planet gear and fourth planet gear engage with central gear and rim gear wheel simultaneously;
Frame includes the first frame and the second frame, and the first frame includes first planet gear supporting portion, and the second frame includes the second Supporting Planetary Gears portion;
First planet gear and third planet gear are rotatably arranged on first planet gear supporting portion, and the second planetary gear and fourth planet gear are rotatably arranged on the second Supporting Planetary Gears portion.
In order to extend the service life of support body, support body adopts stainless steel to make.
The invention has the beneficial effects as follows: the present invention can effectively solve the problem that output link cannot position accurately there is transformation simple, long service life, reduces the beneficial effects such as cost.

Detailed description of the invention
Below in conjunction with drawings and Examples
The invention will be further described:
As shown in Figure 1-Figure 3, a kind of new gear structure, including central gear 20, rim gear wheel 30 and support body 50, described central gear 20 is set on power shaft 2, described rim gear wheel 30 is set on output shaft 4, is provided with first planet gear the 41, second planetary gear 42, third planet gear 43 and fourth planet gear 44 between central gear 20 and rim gear wheel 30; The module of first planet gear 41 is 4;
First planet gear the 41, second planetary gear 42, third planet gear 43 and fourth planet gear 44 engage with central gear 20 and rim gear wheel 30 simultaneously;
Frame 50 includes the first frame 52 and the second frame 56, and the first frame 52 includes first planet gear supporting portion 53, and the second frame 56 includes the second Supporting Planetary Gears portion 54;
First planet gear 41 and third planet gear 43 are rotatably arranged on first planet gear supporting portion 53, and the second planetary gear 42 is rotatably arranged on the second Supporting Planetary Gears portion 54 with fourth planet gear 44;
It is provided with depressed part 55 between first planet gear supporting portion 53 and the second Supporting Planetary Gears portion 54; First frame 52 and the second frame 56 are positioned at this depressed part 55, are fixed by depressed part 55, to improve the stable degree of the first frame 52 and the second frame 56.
Frame 50 is provided with the first screw the 61, second screw the 62, the 3rd screw 63 and the 4th screw 64; First screw 61 traverse the first frame 52 and the second frame 56, and between first planet gear 41 second Supporting Planetary Gears portion 54; Second screw 63 is arranged between third planet gear 43 and fourth planet gear 44. Support body 50 adopts stainless steel to make.
The present invention utilize first screw the 61, second screw the 62, the 3rd screw 63 and the 4th screw 64 form an adjustment means, this adjustment means is utilized to adjust the first frame 52 and the second frame 56, by first screw the 61, second screw the 62, the 3rd screw 63 and the 4th screw 64, first frame 52 and the second frame 56 are adjusted, so that the position of rotation of output link can with control problem correct in high precision, it is possible to solve.
In the present invention, central gear 20 and rim gear wheel 30 can peripherally rotate in direction, support body 50 then cannot rotate in circumferential direction, it is to say, in so-called planetary gear row (form that rim gear wheel will not rotate), central gear (form that will not rotate) and planetary gear (form that bracket will not rotate). central gear 20 is relative to a housing, and can peripherally support in the way of rotating in direction, in the present embodiment, power shaft 2 is to combine to central gear 20, and makes its rotation axis coincident. when power shaft 2 rotates, central gear 20 is to rotate together with power shaft 2. rim gear wheel 30 is a gear being positioned at along radial direction outside central gear 20. this rim gear wheel 30 be relative to this housing can peripherally direction rotate mode support, when rim gear wheel 30 rotates, output shaft 4 is to rotate together with rim gear wheel 30. first planet gear 41, second planetary gear 42, between third planet gear 43 and fourth planet gear 44, each spacing is 90 ��, and arrange in circumferential direction, the order that its peripherally direction such as grade is arranged is planetary gear 41, second planetary gear 42, third planet gear 43 and fourth planet gear 44, this planetary gear 41, second planetary gear 42, third planet gear 43 and fourth planet gear 44 engage with central gear 30, thus the spinning force of the central gear 20 rotated together with output shaft 2 can be transferred on the rim gear wheel 30 that output shaft 4 rotates together via planetary gear.
The preferred embodiment of the present invention described in detail above. Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work. Therefore, all technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
