Abstract
The utility model relates to a feed through acceleration and deceleration mechanism, which mainly consists of a power shaft with an external gear, a plurality of double-layered transmission gears and a ring-shaped fluted disc with an internal gear. The transmission gears are in surrounding arrangement around the power shaft, a first layer of gears of the transmission gears is jointed with the external gear, and the power shaft penetrates through the ring-shaped fluted disc so as to enable a second layer of each transmission gear to be jointed with the internal gear. By aid of the mentioned arrangement, power acceleration and deceleration of the power shaft can be transmitted to the ring-shaped fluted disc to output. The transmission gears are in surrounding arrangement between the power shaft and the ring-shaped fluted disc, thereby being capable of counteracting eccentric force of gear transmission, enabling power transmission to be more direct and quieter, and simultaneously being capable of bearing power of higher torsion force. Secondarily, the power shaft penetrates through the ring-shaped fluted disc, which enables power input and power output to be coaxial and can reduce required space for arranging the acceleration and deceleration mechanism. Besides, an input shaft and an output shaft can be utilized as an accelerator when the input shaft and the output shaft are opposite.

Embodiment
Now sincerely form with regard to the structure of the utility model feedthrough acceleration and deceleration mechanism, and the effect that is produced, cooperate graphicly, the preferred embodiment of lifting a this case is described in detail as follows:
Head sees also Fig. 1 and shown in Figure 2, and this case feedthrough acceleration and deceleration mechanism includes body 1, line shaft 2, driving gear 3, positioning plate 4, annular fluted disc 5 and cover plate 6.Body 1 is the bowl-type housing, is used for ccontaining each parts, and the center has axis hole 11.Line shaft 2 is cylinders, and the outside is provided with external gear 21, and the cylinder axle center is penetrating hollow portion 22.Driving gear 3 is double-layer gears, and it is divided into first layer gear 31 and second layer gear 32, and the diameter of first layer gear 31 is bigger than second layer gear 32.Positioning plate 4 is a plate body, has a central hole 41 and some positioning holes 42 on it.5 of ring gears are a ware shape disk, and its inner concave sidewall has internal gear 51, and there is an opening 52 at the disk center place, are extended with the end 53 of exerting oneself of a hollow tube toward the direction of trying to get to the heart of a matter by opening 52.Cover plate 6 also is a plate body, and the center has an axis hole 61.
Then see also Fig. 3, Fig. 4 and shown in Figure 5, it is above-mentioned each parts combination schematic representation.At first get a body 1, line shaft 2 is penetrated axis hole 11, and external gear 21 is positioned at body 1 inboard.Then get three groups of driving gears 3, with first layer gear 31 inwardly, the outside direction of second layer gear inserts body 1 inboard, and equidistantly is looped around line shaft 2 peripheries, its first layer gear 31 all with external gear 21 engagements.Getting a positioning plate 4 again wears and is bonded on line shaft 2 and the driving gear 3 its central hole 41 involutory line shafts 2, positioning hole 42 involutory driving gears 3.Then, annular fluted disc 5 is incorporated in the body 1, makes line shaft 2 pass opening 52, internal gear 51 and 32 engagements of second layer gear.Get cover plate 6 at last and cover, and make line shaft 2 and the end of exerting oneself 53 passes axis hole 61 at body 1.
See also Fig. 6 and shown in Figure 7 at last, it is the related schematic representation of action of line shaft 2, driving gear 3 and annular fluted disc 5.When line shaft 2 rotates, external gear 21 drives first layer gear 31 earlier and then rotates driving gear 3, and then second layer gear drives internal gear 51 again annular fluted disc 5 is rotated, and it is available that the end 53 of exerting oneself promptly has power.Because first layer gear 31 and the different teeth of second layer gear 32 diameters than different, drive large diameter internal gear 51 again, reduce rotating speed and promote torsion with the power that line shaft 2 is passed to the end 53 of exerting oneself.
