Abstract
The utility model relates to a differential planet driving gear box with four distributary centers, which adopts two groups of epicyclic gearing with the same structure; each of the groups of epicyclic gearing respectively comprises a sun gear, a planet gear, a revolving rack and a gear ring; when the sun wheel rotates, two transmission routes are formed; one of the transmission routes is the sun gear, the planet gear, a ring gear, an external tooth ring, a gear 5, a gear 7 are transferred to a gear 11; the other transmission route is the sun gear, the planet gear, the revolving rack, a gear 8 are transferred to the gear 11. Therefore, the two same epicyclic gearing are formed into four transmission routes to drive the gear 11 together. The utility model increases the transmission power of the gear box and the load bearing capability of an output gear in duplication; the service life of the utility model is prolonged.
Description
The utility model relates to a kind of improvement of speed-changing gear box, and the squeezer and the cement mill (pipe mill) that are particularly suitable for sugar industry drive supporting use.
The patentee has applied for patent (patent No. 92224523.1) on June 11st, 1992 to Patent Office of the People's Republic of China.In this patent, adopted one group of epicyclic gear train to replace two speed-changing gear boxs in the past.Thereby not only obtained bigger transmission speed ratio, make the more compact structure of gear-box; Realize power bi-shunting again, satisfied technological requirement; Also improve the bearing capacity and the working life of output gear, improved the technology capability of gear-box.Along with the continuous development of modern technologies, the technical requirements of speed-changing gear box is further improved.Therefore, aspects such as the transmission power of this gear-box, bearing capacity have just seemed some gap.
Task of the present utility model provides a kind of improvement of gear-box, and this kind gear-box compared with prior art should have bigger transmission power, higher bearing capacity and longer working life.
The utility model has adopted following technological scheme:
This gear-box has an input shaft, three output shafts.Input shaft is gone up the epicyclic gear train that two affixed gears drive two groups of same structures that comprise sun gear, planet wheel, pivoted frame and gear ring respectively by it, in each epicyclic gear train: input shaft drives sun gear 2,6 output shafts that are connected with gear 11 by gear 8 drivings of pivoted frame, gear ring also drives the output shaft that is connected with gear 11 by gear 5, gear 7, and this output shaft drives the output shaft that is connected with gear 12 with gear 9 respectively by the gear 10 on it again.Constitute the mode of four common actuation gears 11 of drive path.
The utility model by four route transferring power, makes that the transmission power of gear-box and the bearing capacity of output gear are significantly improved owing to adopted two groups of epicyclic gear trains, working life significant prolongation.In addition, the herringbone tooth structure that the gear 15 on this gearbox input shaft, gear 17 are formed has the function in looking for automatically, and two groups of epicyclic gear trains have the effect of all carrying about making.Adopt epicyclic gear train (differential planetary device) to make simultaneously and reach the effect that power all carries between the gear 7 in the epicyclic gear train, gear 8 (or gear 13, gear 14).In addition because gear-box is a symplex structure, and all transmission shafts (except that planet pin) counterpoise is combined on five axis, makes the manufacturing procedure simplification, and technology capability is improved.
Further specify below in conjunction with embodiment shown in the drawings.
Fig. 1 is the expansion schematic representation of transmission system of the present utility model.
Fig. 2 is an operative gear meshing relation schematic representation of the present utility model.
As shown in Figure 1, input shaft 16 is by its epicyclic gear train that goes up affixed two groups of same structures of two gear drive, and every group of epicyclic gear train includes sun gear, planet wheel, pivoted frame and gear ring.Sun gear 2 circumferentially is the gear ring that is positioned the rotating planet wheel 1 on the pivoted frame 6 and can rotates around the sun gear axis.Be shaped on ring gear 8 and external toothing 4 on the gear ring, planet wheel meshes with ring gear and sun gear simultaneously, and pivoted frame also can rotate around the sun gear axis.Because 5 engagements of external toothing and gear, and by gear 7 and gear 11 engagements, so just form two drive paths during the sun gear rotation: one is sun gear, planet wheel, ring gear, external toothing, gear 5, gear 7, gear 11; Another is sun gear, planet wheel, pivoted frame, gear 8 (gear 8 is affixed with turret shaft), gear 11.Like this, two epicyclic gear trains just form four common actuation gears 11 of drive path.And backgear 11 drives output shaft that is connected with gear 9 and the output shaft that is connected with gear 12 respectively by the gear on the output shaft that it connected 10, carries out power output.
Fig. 2 has represented the relevant gear meshing relation in this gear-box.As we know from the figure: gear 7, gear 8, gear 13 and 14 whiles of gear and gear 11 mesh and are distributed in around the gear 11, form the common structure that drives a gear of four gears.
Claims (2)
