TRANSDUCING AND COMPENSATING DEVICE FOR ANGLE VARIATIONS IN PIPELINES |
摘要 |
Two rigid cylindrical sleeves are interconnected by a spring bellows. Each cylindrical sleeve carries a flange section. Such flange section is provided with joint plates. The joint plates are a forklike interconnecting structure. A rolling contact wedge member is located in a first number of joint plates and a rolling contact prism member is located in a second number of joint plates. This provides for a hinge-like joint of a rolling contact rocker structure having a line contact only of the parts moving relative to each other. Because no friction exists in such hinge joint, a cold welding is not possible. Accordingly, no additional stresses due to such cold welding will be able to exist in the pipe conduit sections interconnected by this apparatus. |
