| 摘要 |
The invention relates to a method for producing a twin screw cylinder (1) provided with a wear-protective layer, according to which method two bores (11, 12), which run substantially parallel to each other and overlap each other, are made in a cylinder, and then two linings (21, 22) are introduced into the bores (11, 12), said linings being provided with a substantially C-shaped cross section, continuing from each other in the overlap region (10) of the bores (11, 12), forming the inner surface (110, 120) of the bores (11, 12) and acting as a wear-protective layer. The method is characterised in that firstly a first tubular lining (21) is introduced into a first of the bores (11) and is subsequently cut open in accordance with the diameter (D) of the other bore (12) to form the C-shaped cross section, and then a second tubular lining (22) is introduced into the second of the bores (12) and is subsequently cut open in accordance with the diameter (A) of the inner surface (110) of the first bore (11), said surface being formed by the first lining (21), thus forming the C-shaped cross section. |
