Abstract
The invention relates to a high-strength low-torsion lining structure which comprises an inner sleeve, an outer sleeve and a rubber layer. The inner sleeve and the outer sleeve are cylindrical metal barrels. The inner sleeve is arranged in an inner cavity of the outer sleeve. The inner sleeve and the outer sleeve are coaxial. The rubber layer is arranged between the inner sleeve and the outer sleeve. The inner sleeve and the rubber layer are tightly attached and fixed together, and the rubber layer and the outer sleeve are tightly attached and fixed together. The middle of the inner sleeve protrudes outwards to form a protrusion. The two ends of the inner sleeve are cylindrical. The protrusion in the center of the inner sleeve is in arc-shaped butt joint with the cylindrical portions at the two ends. Compared with a traditional straight-cylinder-shaped inner sleeve, the rigidity of a product is greatly improved; for rigidity changes in other directions, the radial rigidity is improved fastest, so that the effect that torsion and deviation are relatively reduced is achieved; and in addition, due to the fact that the portions, at the tow ends of the inner sleeve, of the rubber layer are thick, the high endurance quality is achieved under the endurance working condition of the large torsion angle.
