Study on the transmission system of twin-screw extruderStudy on the transmission system of twin-screw extruder
In this paper, the role of the transmission system of the twin-screw extruder is described, and the two new transmission schemes to achieve the design goals of the transmission system are analyzed, and the selection principle of the drive mode of the transmission system is discussed.
The transmission system of the twin-screw extruder is one of the key parts of the twin-screw extruder. Its role is to provide the two screws with a suitable speed range, stable and uniform speed under the set process conditions, and it is sufficient and Uniform and equal torque (power), and can withstand the huge axial force of the screw produced by the completion of the extrusion process. To achieve the goals of prescribed screw speed, screw rotation direction, even torque distribution, and reasonable bearing arrangement, it is necessary to determine a reasonable transmission scheme and structural design in the design of the transmission system.
1 Analysis of new transmission scheme of twin-screw extruder
Twin screw extruder transmission system design is a comprehensive design, its design represents the level and working performance of the entire model. The new transmission system of the twin-screw extruder enables the twin-screw extruder to increase the service life and greatly enhance the torque of the twin-screw drive, and truly achieve the "three high" "optimization. The following is an analysis of two new transmission systems for twin-screw extruders.
1.1 Drive system for twin-screw extruder with high torque and co-rotation
In recent years, the co-rotating twin-screw extruder has developed rapidly, its output, torque and speed have been greatly improved, and its application has become increasingly widespread.
