Description
Technical field
The utility model belongs to liquefaction field of mechanical technique, is specifically related to a kind of transmission device of twin-screw cold pressing expeller.
Background technology
Screw oil expeller is applied to extract grease widely from oil plant, one of liquefaction machinery main in the world today, twin-screw cold pressing expeller is wherein owing to being applicable to cold pressing process, squeeze the oil plant adverse effect of having avoided high temperature to produce, can farthest keep original nutritional labeling and active material, progressively universal coming.
Twin-screw cold pressing expeller is generally comprised of transmission device, drawing-in device, pressing device He Chu cake mechanism, and the power that wherein transmission device is responsible for motor to provide is delivered on two screw rods with certain rotating speed and moment of torsion, guarantees that material is by continuous extruding and propelling.In transmission device, most crucial part is the drive unit of twin-screw, and its function is that the moment of torsion of system input is assigned on two screw rods fifty-fifty, drives two screw rods to make the synchronous counter rotating of constant speed.
At work, two low speed rotation screw rods are in extruding and promote to need to bear huge moment of torsion and axial force in process that oil plant advances, and the spiral on two screw rods needs intermeshing feature determine that between two screw rods, centre-to-centre spacing is less simultaneously.Therefore, low speed, high moment of torsion and centre-to-centre spacing are little is the typical feature of twin-screw cold pressing expeller.This design feature has limited the structure of travelling gear and bearing.The drive unit of screw rod generally adopts two-axis transmission system at present, by a pair of helical gear, the moment of torsion of motor is assigned on two screw rods fifty-fifty, although this can improve the intensity of gear and the size of dwindling gear to a certain extent, but helical gear engagement can produce larger axial force, this axial force and the axial force being produced by screw rod can form larger axially making a concerted effort, thereby make bearing group bear very large axial load, the service life of bearing and the reliability of whole transmission system all can reduce.
Utility model content
The purpose of this utility model is to provide a kind of transmission device of twin-screw cold pressing expeller, to improve reliability and the service life of transmission system.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A twin-screw cold pressing expeller transmission device, comprises belt transmission system, decelerator, the first shaft coupling, spiro driving device and the second shaft coupling; Described spiro driving device comprises intermeshing driving gear shaft and driven gear shaft, and described driving gear shaft and driven gear shaft left end are provided with thrust bearing and radial bearing, and right-hand member is provided with radial bearing and radial thrust bearing; Described driving gear shaft is herringbone gear shaft with driven gear shaft and the number of gears is identical.
Further, described driving gear shaft is identical with the gear width on driven gear shaft.
Driving gear shaft and driven gear shaft in spiro driving device of the present utility model are herringbone bear, its bearing capacity is large, engagement steadily, efficiency is high, the life-span is long, noise is low, can effectively guarantee that gear normally works; During its engagement, owing to not producing extra axial force, can either greatly extend the service life of bearing arrangement; Can make again its helical angle design greatlyr, thereby make the size of whole gear less, meet the less requirement of twin-screw cold pressing expeller two screw rods centre-to-centre spacing; And under given centre-to-centre spacing, can select larger modulus, thereby improve the bearing capacity of gear.Driving and driven gear shaft of the present utility model both sides are provided with the bearing group being comprised of radial bearing, thrust bearing and radial thrust bearing and bear radial and axial power, can be by power and average being assigned on two rooted tooth wheel shafts of moment of torsion, can reduce the fault rate of whole transmission device, promote the operating efficiency of twin-screw cold pressing expeller.
Accompanying drawing explanation
Fig. 1 is transmission sketch of the present utility model.
In figure, 1. motor, 2. belt transmission system, 3. decelerator, 4. the first shaft coupling, 5. spiro driving device (51. driving gear shafts, 52. driven gear shafts, 53. thrust bearings, 54. radial bearings, 55. radial thrust bearings), 6. the second shaft coupling, 7. screw rod.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model is a kind of transmission device of twin-screw cold pressing expeller.This transmission device comprises belt transmission system 2, decelerator 3, the first shaft coupling 4, spiro driving device 5 and the second shaft coupling 6; Described spiro driving device 5 comprises intermeshing driving gear shaft 51 and driven gear shaft 52, described driving gear shaft 51 and driven gear shaft 52 left ends are provided with thrust bearing 53 and radial bearing 54, and right-hand member is provided with radial bearing 54 and radial thrust bearing 55; Described driving gear shaft 51 is herringbone gear shaft with driven gear shaft 52 and the number of gears is identical.Because the gear on driving gear shaft and driven gear shaft bears equal moment of torsion, therefore, when the width design of the two gear is when equating, can more meet economy principle.
The course of work of this transmission device is as follows: motor 1 arrives decelerator 3 through primary speed-down by transmission of power by belt transmission system 2, after the double reduction of decelerator 3, by the first shaft coupling 4, transmission of power is arrived to driving gear shaft 51, because driving gear shaft 51 is intermeshing with driven gear shaft 52 and the number of gears is identical, so driven gear shaft 52 and driving gear shaft 51 constant speed counter rotatings, simultaneously by average being assigned on driving gear shaft 51 and driven gear shaft 52 of moment of torsion, finally respectively by be connected with driven gear shaft 52 with driving gear shaft 51 the second shaft coupling 6 by transmission of power, give two screw rods 7.The bearing group being comprised of thrust bearing 53, radial bearing 54, radial thrust bearing 55 that is arranged on gear shaft two ends is born radial and axial power, can guarantee the normal work of gear shaft and screw rod.
