When the outer ring of the bearing and the outer end surface of the end cap are formed into a cone, the cone tops of the two conical faces must be coincident. When the outer ring of the bearing and the outer end surface of the end cap are made into a hyperbolic conical surface, the structure is complicated in order to meet the requirements of the corresponding point speed of the contact. In the application, we machine the outer ring of the bearing into an oblique angle of 2.50 with the axial direction, which coincides with the conical surface of the end cap. The working principle of the transmission box and the thrust device The working principle of the thrust device.
The screw acts on the roller bearing through the output shaft washer and the end cap, and the bearing acts on the box body through the support shaft, and the internal force balance is formed by the same force generated when the hoop and the material are extruded. The structure of the transmission case and the thrust loading is a structural diagram of the transmission case and the thrust device. The rear ends of the shafts 17 and 18 are provided with end caps 8 and 29, and an adjusting pad is arranged between the inner hole of the end cap and the rear end of the output shaft, which can be used to adjust the position of the end cap, and the front end of the outer end of the end cap respectively corresponds to The outer cylindrical surface of a set of concentric cylindrical roller bearings (1, 2, 3, 5) is in contact. The outer circumference of each set of bearings. The cylinder is machined into a forming surface that conforms to the shape of the outer end surface of the end cap that is in contact. The bearings 1, 2, 3, 5 are all mounted on the support shaft 6. In order to ensure that the outer ring of the bearing and the outer end of the end cap are always in good contact, the outer ring of the bearing should be reworked.
In order to improve the mixing effect, two mixing elements are designed in the screw, one is a pin-shaped reverse threaded element; the other is a toothed disc-shaped mixing element in the extrusion section. Through the production test, the mixing requirements were fully met. Development of counter-rotating twin-screw The counter-rotating twin-screw was developed on the basis of the screw of cM228o-18D counter-rotating twin-screw extruder produced by Cincinnati Company of Austria, and the original length-to-diameter ratio was changed to 21, and The pin-shaped mixing elements are added to significantly improve the quality of the plastic products.
