Abstract

The invention relates to a distribution box for gear staggered engagement of a co-rotating twin-screw extruder, wherein the distribution box belongs to a part in the co-rotating twin-screw extrude, is particularly applicable to a conical co-rotating twin-screw extruder and can also be used for a parallel co-rotating twin-screw extruder. The distribution box for gear staggered engagement of the co-rotating twin-screw extruder comprises a box body, a driving shaft on which a driving gear is installed, an intermediate shaft on which an intermediate gear is installed and a driven shaft on which a driven shaft is installed, wherein the driving shaft, the intermediate shaft and the driven shaft are installed in the box body through bearings, the number of the intermediate gear is only one, the driving gear is engaged with one portion of the intermediate gear, the other portion of the intermediate gear is engaged with the driven gear, and the axial position of the driving gear in engagement with the intermediate gear and the axial position of the intermediate gear in engagement with the driven gear are staggered. The distribution box for gear staggered engagement of the co-rotating twin-screw extruder has the advantages that the structure is simple, the use is facilitated and the performance is reliable. The co-rotating twin-screw extruder using the distribution box provided by the invention has the advantages of great bearing capacity, high yield, good energy saving effect, high plasticization performance and low noise.

Description

technical field [0001] The invention relates to a distribution box, which is used for a co-rotating twin-screw extruder, and belongs to a part of the co-rotating twin-screw extruder, and is especially suitable for conical co-rotating twin-screw extruders, and can also be used for parallel co-rotating twin-screw extruders. Twin-screw extruder. Background technique [0002] The distribution box is an important component of the twin-screw extruder, which plays a vital role in the transmission and distribution of torque, and its structural design directly affects the normal operation of the twin-screw extruder. The distribution box of the twin-screw extruder is limited by the center distance of the screws, especially the distribution box of the co-rotating twin-screw extruder. , large torque, large axial bearing capacity and other requirements, the design is more difficult. [0003] At present, the basic structure of the distribution box of the commonly used parallel twin-scre...
