Background technique
Gear is generally as acceleration or deceleration effect, existing gear generally all comprises sun gear, bracket, ring gear and planetary pinion, but the engagement place of planetary pinion and sun gear and ring gear can produce back clearance, due to the existence of 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 rotational position of epicyclic gear mechanism arrangement, thus cause output link to 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 above-mentioned defect of prior art, those skilled in the art are devoted to exploitation one can carry out pinpoint gear structure.
Technical problem to be solved by this invention is to provide a kind of high class gear, it is characterized in that: comprise sun gear, ring gear and support body, sun gear is set on input shaft, ring gear is set on output shaft, is provided with first planet gear, the second planetary pinion, third planet gear and fourth planet gear between sun gear and ring gear;
First planet gear, the second planetary pinion, third planet gear and fourth planet gear engage with sun gear and ring gear simultaneously;
Frame comprises the first frame and the second frame;
First planet gear and third planet gear is rotatable is arranged in the first frame, the second planetary pinion and fourth planet gear is rotatable is arranged on the second frame;
Depressed part is provided with between first planet gear supporting portion and the second Supporting Planetary Gears portion.
In order to extend the working life of support body, support body adopts stainless steel to make.
The invention has the beneficial effects as follows: the present invention effectively can solve the problem that output link cannot position accurately to there is transformation simple, long service life, the beneficial effect such as to reduce costs.

Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the A-A sectional structure schematic diagram in Fig. 1 of the present invention.
Fig. 3 is the B-B sectional structure schematic diagram in Fig. 1 of the present invention.
Embodiment
Below in conjunction with drawings and Examples
The invention will be further described:
As shown in Figure 1-Figure 3, a kind of high class gear, comprise sun gear 20, ring gear 30 and support body 50, described sun gear 20 is set on input shaft 2, described ring gear 30 is set on output shaft 4, is provided with first planet gear 41, second planetary pinion 42, third planet gear 43 and fourth planet gear 44 between sun gear 20 and ring gear 30;
First planet gear 41, second planetary pinion 42, third planet gear 43 and fourth planet gear 44 engage with sun gear 20 and ring gear 30 simultaneously;
Frame 50 comprises the first frame 52 and the second frame 56, first frame 52 and comprises first planet gear supporting portion 53, second frame 56 and comprise the second Supporting Planetary Gears portion 54;
First planet gear 41 is arranged on first planet gear supporting portion 53 with third planet gear 43 is rotatable, and the second planetary pinion 42 is arranged on the second Supporting Planetary Gears portion 54 with fourth planet gear 44 is rotatable;
Depressed part 55 is provided with 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 61, second screw 62, the 3rd screw 63 and the 4th screw 64; First screw 61 passes 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 first screw 61, second screw 62, the 3rd screw 63 and the 4th screw 64 is utilized to form an adjusting member in the present invention, utilize this adjusting member to adjust the first frame 52 and the second frame 56, by the first screw 61, second screw 62, the 3rd screw 63 and the 4th screw 64, first frame 52 and the second frame 56 are adjusted, so that the rotational position of output link with the correct control problem of highi degree of accuracy, can be able to be solved.
In the present invention, sun gear 20 and ring gear 30 can peripherally rotate in direction, support body 50 then cannot rotate in circumferential direction, that is, in so-called planetary pinion capable (form that ring gear can not rotate), sun gear (form that can not rotate) and planetary gear (form that bracket can not rotate).Sun gear 20 is relative to a housing, with can peripherally direction rotate mode support, in the present embodiment, input shaft 2 is bonded on sun gear 20, and make its rotation axis coincident.When input shaft 2 rotates, sun gear 20 rotates together with input shaft 2.Ring gear 30 be one radially direction be positioned at the gear outside sun gear 20.This ring gear 30 be relative to this housing can peripherally direction rotate mode support, when ring gear 30 rotates, output shaft 4 rotates together with ring gear 30.First planet gear 41, second planetary pinion 42, between third planet gear 43 and fourth planet gear 44, each spacing is 90 °, and arrange in circumferential direction, the order that peripherally direction is arranged such as its grade is planetary pinion 41, second planetary pinion 42, third planet gear 43 and fourth planet gear 44, this planetary pinion 41, second planetary pinion 42, third planet gear 43 and fourth planet gear 44 engage with sun gear 30, thus the spinning force of the sun gear 20 rotated together with output shaft 2 can be passed on the ring gear 30 that output shaft 4 rotates together via planetary pinion.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
