3, connecting component is more between motor and small tooth shaft, and dismounting, maintenance are inconvenient；
4, the transmission ratio between empty axis and small tooth shaft is excessive, and energy loss is big；
5, the transmission arm of force between empty axis and small tooth shaft is short, and torsion loss is big.
Utility model content
The utility model discloses a kind of granulator compound gearings, it is intended to improve traditional granulator sky axis driving methodExisting drawbacks described above.
The utility model adopts the technical scheme that
A kind of granulator compound gearing, including empty axis further include a small tooth shaft and two motors；It is set on the sky axisThere is gear wheel, the small tooth shaft is equipped with the pinion gear being meshed with the gear wheel, so that the small tooth shaft is sequentially connectedIn the empty axis；Small pulley is equipped on the output shaft of two motors, two small pulleys pass through one group of belt respectivelyIt is connected in big belt wheel set in the small tooth shaft, so that two motor drives are connected to the small tooth shaft.
Preferably, rotation is installed on same cabinet in parallel to each other for the empty axis and small tooth shaft, described smallGear and gear wheel are mounted in the cabinet；
Two equal output shafts of motor are fixedly installed in parallelly with the small tooth shaft on same motor chassis, and twoThe small pulley is divided into two wheel carriers set on the motor chassis and with the big belt wheel in the motor chassisRealize connection；
It apart is set on same pedestal before and after the cabinet and motor chassis.
Preferably, two motors are divided into the left and right sides oblique upper of the small tooth shaft.
Preferably, it closely pushes up the left and right sides that two wheel carriers are divided into the motor chassis in tandemPortion.
Preferably, the bearing block for assisting the cabinet to support the small tooth shaft is additionally provided on the pedestal.
Preferably, the bearing block is set to the tail end of the small tooth shaft.
Preferably, the bearing block is set to the middle part of the small tooth shaft.
The utility model is set there are two driving motor, and two driving motors pass through wheel belt device and small tooth shaft is flexibly connectedSmall tooth shaft rotation is driven with synchronous, which has the following beneficial effects:
1, empty axis and small tooth shaft can get rotary inertia, reduce motor load, the loss of electric machine is smaller, and service life is moreIt is long；
2, flexible connection can provide effectively buffering and reduce noise and failure rate to protect machinery between motor and small tooth shaft；
3, the connection structure between each transmission parts is simpler, is more convenient for dismounting and repair；
4, the transmission ratio between small tooth shaft and empty axis can be improved, improve energy transfer efficiency, efficiency is higher；
5, the effective arm between small tooth shaft and empty axis can be increased, increase torsion output, improve energy utilization rate, furtherEnergy conservation；
6, bi-motor is conducive to provide driving stability that is higher, more balancing and stronger torsion.
7, by changing belt pulley size, revolving speed and torque suitable for different operating conditions be can get.

Fig. 1 is the general structure schematic diagram of the utility model embodiment；
Fig. 2 is the partial structural diagram of the utility model embodiment.
Specific embodiment
The utility model is illustrated in the following with reference to the drawings and specific embodiments.
Referring to Figures 1 and 2:
A kind of granulator compound gearing, including pedestal 1, front and back is apart equipped with cabinet 2 and motor chassis on pedestal 13。
Rotation is equipped with the empty axis 4 and small tooth shaft 5 of front and back trend in parallel to each other on cabinet 2.
Empty axis 4 is set to the underface of small tooth shaft 5, and front end is exposed except cabinet 2, and front end exposed division is equipped with granulation moldComponent 6.
The rear end of small tooth shaft 5 is exposed except cabinet 2 and is probeed into motor chassis 3, and its rear end is equipped with big belt wheel 7.
Gear wheel 8 and pinion gear 9 are respectively equipped on empty axis 4 and small tooth shaft 5, the diameter of gear wheel 8 is greater than the straight of pinion gear 9Diameter, gear wheel 8 and pinion gear 9 are set in cabinet 2 and are intermeshed, and empty axis 4 is sequentially connected in small tooth shaft 5.
The left and right sides proximal portion of motor chassis 3 is not equipped with a motor 10, and two motors 10 are located at a left side for sky axis 4Right two sides oblique upper and output shaft is parallel with empty axis 4.
Small pulley 11 is equipped on the output shaft of two motors 10, two belt pulleys 11 are respectively arranged on motor chassis 3 or soIn the wheel carrier 12 that the nearly top in two sides is one in front and one in back arranged.
Two wheel carriers 12 are communicated with motor chassis 3, so that two small pulleys 11 can be respectively by one group of belt 13 in electricityBig belt wheel 7 is connected to inside machine chassis 3, thus by two transmission connections of motor 10 in small tooth shaft 5.
Bearing block 14 is additionally provided on pedestal 1 between cabinet 2 and motor chassis 3, the rotating middle part of small tooth shaft 5 is set to the axisIt holds in seat 14 to be supported on pedestal 1 by 14 auxiliary chamber 2 of bearing block.
When work, two motors 10 drive small tooth shaft 5 to rotate by the way that respective belt 13 is synchronous, and small tooth shaft 5 passes through gearDevice drives empty axis 4 to rotate, so that the granulation die assembly 6 on empty axis 4 be driven to rotate.
