A twin-screw gearbox is a gearbox with a twin-screw structure, and this type of gearbox can also be used on the extruder.
A twin-screw gearbox that can be reclassified, such as a parallel twin-screw gearbox, can be used on a parallel forward-reverse twin-screw extruder and used as a transmission component. In addition to the parallel twin-screw gearbox, there are other specific types.
Twin-screw gearboxes, there are many in specific applications, but they are still used in extruders. In the specific types of extruders, there are twin-screw extruders, twin-screw high-low extruders, etc. . And, these extruders have something in common, which is:
(1) The gear and the shaft surface are made of alloy steel, and it is a high-strength alloy steel, and some processes are carried out to obtain good performance and use effect.
(2) The gear box can be selected according to different sizes of bearings or bearing combinations, and imported parts are also used on bearings and oil seals.
(3) The whole machine can be equipped with an oil pump circulation or cooling system to extend the service life of the equipment.
Twin-screw gearboxes are available in different models, and different models have different meanings, so let's take a look at the examples below.
TPS52S: T refers to the same direction, PS refers to the parallel twin screw, 52 refers to the center distance of the two screws, and the upper capital letter S refers to the three-open box structure. If not, it refers to the two open box structures.
YPS140K: Y refers to the opposite direction, PS refers to the parallel twin screw, 140 refers to the center distance of the two screws, and the capital letter K at the back means that this type of gear box is used on the pellet machine, so the twin screw gear The center of the box is relatively large.
