Abstract
The utility model relates to a differential planet double-divided flow centre driving gear box for driving a presser. The utility model is provided with an input shaft and three output shafts with constant specific speed, and the utility model is also provided with an epicyclic wheel train which comprises a sun wheel, a planet wheel, a rotating frame and a gear ring, wherein, the sun wheel is driven by the input shaft through a gear, a gear 11 is driven by the rotating frame through a gear, the gear 11 is also driven by the gear ring through a gear, and a gear 6 and a gear 8 are driven by the gear 11. The utility model has the advantages of high transmission speed ratio, compact structure and enhanced operational reliability, and furthermore, processing manufacturability is obviously improved.
Description
The utility model relates to a kind of speed-changing gear box, especially for the gear-box of drive pressure crusher.
The structure of the existing speed-changing gear box that is used for the drive pressure crusher as shown in Figure 2.Its power by grade III Standard gear-box 14 speed changes, then drives the gear in the composite teeth roller box 13 after being imported by input shaft, is become the rotating speed output of constant proportion example by three output shafts.The speed ratio of this gear generally all is restricted (all being less than or equal to 75); And adopted two gear box combination to form, and floor space is bigger, and its lengthwise position often is subjected to spatial constraints again easily.In addition, the reliability of this kind mechanism is also relatively poor.
Task of the present utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of gear-box is provided, and it is bigger that this kind gear-box should have a speed ratio, compact structure, the characteristics that reliability is higher.
The utility model provides following technological scheme:
This gear-box still adopts an input shaft, three output shafts that become constant than speed, has adopted the epicyclic gear train that comprises sun gear, planet wheel, pivoted frame and gear ring again.Said input shaft drives sun gear, pivoted frame then drives the output shaft that is connected with gear 11 by gear 5, gear ring also drives the output shaft that is connected with gear 11 by gear 10, gear 9, and gear 5 drives output shaft that is connected with gear 6 and the output shaft that is connected with gear 8 by gear 11 respectively with gear 7 again with gear 9.
Further specify below in conjunction with embodiment shown in the drawings.
Fig. 1 is the expansion schematic representation of the transmission system of present embodiment.
Fig. 2 is the expansion schematic representation of prior art.
As shown in Figure 1, input shaft 12 rotates by gear drive sun gear 1.Sun gear circumferentially is the gear ring that is positioned the rotating planet wheel (planet wheel does not draw) on the pivoted frame 4 and can rotates around the sun gear axis successively.Be shaped on ring gear 2 and external toothing 3 on the gear ring.Because external toothing and gear 10 engagements, and by gear 9 and gear 11 engagements, when therefore sun gear rotates, planet wheel is subjected to sun gear to drive rotation on the one hand, revolve round the sun around sun gear with pivoted frame 4 on the other hand, make gear ring (sense of rotation opposite) rotate (planet wheel while and ring gear 2 and sun gear engagement) by the ring gear that it meshed in addition with sun gear.Thereby gear 5 also actuation gear 11 rotations affixed (rotating) with gear 9 common actuation gears 11 with pivoted frame.Final gear 11 carries out power output by the output shaft (also being the rotatingshaft of self) that it connected; And drive the output shaft that is connected with gear 6 respectively and carry out power output the output shaft that is connected with gear 8 (being the rotatingshaft of self) by gear 11 and gear 7.
The utility model adopts the epicyclic gear train structure, has not only obtained bigger transmission speed ratio, makes gear box structure compacter, can carry out synchronous drive to gear 9 and gear 5 again, has realized power bi-shunting, has satisfied technological requirement.And gear 5 and 9 while of gear actuation gear 11, the bearing capacity and the working life of having improved output gear, the functional reliability of gear-box also has raising.In addition, in the whole gear-box, except the axis hole of input shaft 12, the axis of all the other institute's sprocket drive spindles respectively with the dead in line of three output shafts, the manufacturability that this has just significantly improved the gear-box bore hole makes manufacturing procedure simplify, quality of processing improves.This gear-box also satisfies the requirement of squeezer fully.
Claims (3)
1, a kind of differential planetary double split flow centre-driven gear-box that is used for the drive pressure crusher, has an input shaft, three output shafts that become constant than speed, it is characterized in that this gear-box has also adopted comprises sun gear, planet wheel, pivoted frame and gear ring are in interior epicyclic gear train, said input shaft drives sun gear, pivoted frame then drives the output shaft that is connected with gear 11 by gear 5, gear ring is also by gear 10, gear 9 drives the output shaft that is connected with gear 11, and gear 5 drives the output shaft that is connected with gear 8 with gear 6 by gear 11 respectively with gear 7 respectively again with gear 9.
2, by the said differential planetary double split flow of claim 1 centre-driven gear-box, it is characterized in that in the said epicyclic gear train, planet wheel is rotatably positioned on pivoted frame, and respectively with sun gear engagement and with gear ring in the ring gear engagement, the external toothing in the gear ring then with gear 10 engagements.
3, by claim 1 or 2 said differential planetary double split flow centre-driven gear-boxes, it is characterized in that in this gear-box, except that input shaft 12 and planet wheel, the axis of all the other gear shafts all with the dead in line of three output shafts.
