Abstract
The utility model provides a plasticator gearbox structure which comprises a box body and a shaft. The shaft comprises a main shaft, an auxiliary shaft and an output shaft. The main shaft is connected with a motor. The auxiliary shaft is a middle shaft transmitting with the main shaft. The output shaft is connected with a screw of the plasticator. A thrust bearing is arranged on the main shaft. The thrust bearing is used for resisting extrusion force to the screw from materials in the process of screw extruding. A bearing at the output shaft end of the main shaft is a tapered roller bearing. A bearing at the shaft end of the auxiliary shaft is a tapered roller bearing. According to the plasticator gearbox structure, force to each component in a gearbox is even so that damage of deserved service life of the gearbox is avoided.
Description
Technical field
The utility model relates to plasticizing machine gear box structure.
Background technique
Existing plasticizing machine gear box structure is also installed thrust bearing, and for opposing comes from screw rod in the pressing materials process, material is to the extruding counter-force of screw rod, and the mounting point of thrust bearing is the axle head of output shaft.Push counter-force to the injury of gear-box with this material of offsetting in the During Screw Extrusion.But the harm that this structure is brought is that discontinuity reduces the life-span of gear-box.
The model utility content
In order to overcome above defective, the utility model provides a kind of plasticizing machine gear box structure, and this structure makes each element in the gear-box stressed evenly, the due life-span of not damaging gear-box.
For solving above technical problem, the technological scheme that the utility model provides is as follows: described gear box structure comprises casing and axle, and axle comprises main shaft, secondary axes and output shaft, and main shaft connects motor, and secondary axes are the jack shaft with spindle; Output shaft links to each other with plasticizing machine screw rod; Described main shaft is provided with thrust bearing, and this thrust bearing opposing is from the extruding force of material in the Screw Extrusion to screw rod.
Further, the bearing of described output shaft end is tapered roller bearing.
Further, the axle end bearing of described secondary axes is roller bearing.
This plasticizing machine gear box structure that the utility model relates to has practicability, need not the large-scale transformation to existing equipment, and only need carry out less change can solve the above problem.
Description of drawings
Fig. 1 is the utility model plasticizing machine gear box structure structural representation;
The 1-casing; The 2-thrust bearing; The 3-roller bearing; The 4-roller bearing; The 5-circular cone rolls down bearing; The 6-main shaft; The 7-output shaft.
Embodiment
As shown in Figure 1, described gear box structure comprises casing 1 and axle, and axle comprises main shaft 6, secondary axes and output shaft 7, and main shaft 6 connects motor, and secondary axes are the jack shaft with spindle; Output shaft 7 links to each other with plasticizing machine screw rod; Described main shaft 6 is provided with thrust bearing 2, and these thrust bearing 2 opposings are from the extruding force of material in the Screw Extrusion to screw rod.
The bearing of output shaft 7 ends is tapered roller bearing 5.
The axle end bearing of secondary axes is roller bearing 3.
The output terminal of main shaft 6 is roller bearing 4.
This gear box structure that the utility model relates to is simple, easily manufactured, is the stronger a kind of structure of practicability.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
