A hollow rotor penetrates through the middle of the gear reduction box, the front end and the rear end of a shaft of the hollow rotor are installed on the reduction box through bearings, a spindle disc is arranged on the axis inside the hollow rotor, a driven large gear is fixedly sleeved on the periphery of the hollow rotor, and two driving small gears are arranged below the driven large gear and rotatably installed on the gear reduction box through bearings. The two driving small gears are in meshed connection with the driven large gear and are driven through two driving motors. The two driving small gears are driven through the two driving motors to drive the large gear to rotate, so that the granulator is compact in structure, high in efficiency, low in noise and long in service life, and the double-shaft driving gear transmission system can be used for the high-power ring die granulator.
Description
Technical field
The utility model relates to a kind of ring die pelleter, and particularly a kind of ring die pelleter transmission system belongs to the feed manufacturing machine field.
Background technique
Mostly the gear train assembly that existing ring die pelleter adopts in the feed manufacturing machine field is the single shaft drive system; As disclosing a kind of ring die pelleter in the existing technology, comprise a gear reduction box, in gear reduction box, be provided with gear train and sleeve rotor through the driving gear auxiliary driving; Main shaft disk is installed in sleeve rotor; Be separately installed with pressure roller assembly and ring mould at main shaft disk and sleeve rotor one end, be fixed with ring mould cover, on gear reduction box, be positioned at ring mould one side and be hinged with cover in the ring mould outside; The feeding auger is installed on cover, on the gear reduction box support, is provided with the main motor that is connected with gear train.Continuous development along with feed industry; Demand to high-power ring die pelleter on the market improves constantly; For the high-power ring die pelleter more than 160 kilowatts, the gear train assembly that single shaft drives exists many shortcomings such as single input shaft power is high, the requirement of speed reducing gear pair design contact strength is high, module is big, gear pair engagement contact ratio is low, noise is high, the pinion shaft life-span is low, the gear reduction box cost high, the body longitudinal size is big; In addition; For single shaft actuation gear transmission system because system performance place; When input shaft power is too high; Can be on rotor shaft produce very high monolateral lateral bending power, because pelletization itself is infiltrated impact and the vibration that impurity, foreign matter cause transmission system through regular meeting in the inhomogeneous or material because of feed, the monolateral lateral bending power that at this moment is superimposed upon on the rotor shaft can be very high; The life-span of transmitting assemblies and granulation assembly is reduced, cause adverse effect also for granulation product yield and quality.
The model utility content
The purpose of the utility model provides a kind of ring die pelleter twin shaft actuation gear transmission system, makes that the granulator structure is compact more, efficient is higher, noise is low, long service life.
The purpose of the utility model is achieved in that a kind of ring die pelleter twin shaft actuation gear transmission system, comprises the drive motor and the gear reduction box that are installed on the support, and the middle part of said gear reduction box is run through and is provided with sleeve rotor; Said sleeve rotor the axle front end and back end all through Bearing Installation on speed reducer; The sleeve rotor internal axis is provided with main shaft disk, and the periphery fixed cover of sleeve rotor is equipped with driven gearwheel, and the below of said driven gearwheel is provided with driver pinion; Said driver pinion is installed in rotation on the gear reduction box through bearing; Driver pinion and driven gearwheel are connected with a joggle togather, and an end of said driver pinion is in transmission connection through the output shaft of coupling and said drive motor, and said driver pinion is provided with two; Be symmetrically distributed in the both sides of driven gearwheel; And all be meshed with driven gearwheel, said drive motor also is provided with two, and the output shaft of two drive motor all is in transmission connection through coupling and two driver pinions.
Compared with prior art; The beneficial effect of the utility model is: this device is through adopting two the driving; Make that the power p of monolateral small gear transmission is the half the of the required transmitted power of sleeve rotor; It is original half that the moment of torsion of corresponding transmission
reduces under the constant situation of gear rotational speed r; The suffered normal load
of small gear also is original half the; And then the modulus of small gear can be selected for use littler; The number of teeth can be selected for use more; Thereby in design, can significantly improve gear pair contact ratio and mesh stiffness, make the small gear operation more steadily reliable, longer service life; Simultaneously, through adopting two the driving, gearwheel and sleeve rotor are stressed balanced more; Dynamic characteristic is good, and for single gear train assembly that drives, gearwheel and sleeve rotor had not only received warping force but also power by bending; When sleeve rotor received big torsional load and bending force, the limit bending resistance of sleeve rotor and anti-twisting property can obviously descend, and can make transmission system be easy to vibration; And two actuation gear transmission systems are mainly born torsional load between gearwheel and the sleeve rotor, and two driver pinion symmetries have been offset the most bending force of sleeve rotor; Can improve the stability of pelletization and the life-span of transmitting assemblies effectively; When granulator will take place to block up machine, two drivings can provide the locked-rotor torque of two motors, helped improving the anti-stifled capabilities of granulator; And when starting, can successively start two drive motor respectively, to reduce impact to electrical network.The utility model can be used in the high-power ring die pelleter.
In order to strengthen the stability of this apparatus structure, the reliability when improving operation, the tail end of said main shaft disk is provided with the safety pin dish, and said safety pin dish is fixed on the speed reducer through three safety pins, and three safety pins phase difference each other are 120 °.
