Embodiment Construction

[0031] Fig. 1 is a schematic diagram of the three-dimensional structure of the segmented support roller core of the present invention. Fig. 2 is a schematic view of the longitudinal section of Fig. 1; Fig. 3 is a side view of Fig. 1 . As shown in Fig. 1 and Fig. 2, the present invention segmentally supports the roller core 1, the diameter of the concave platform 10 at both ends of the roller core is smaller than the diameter of the middle part 11 of the segmented roller core, and a concave platform 10 is formed at the two ends of the segmented roller core, so that The segmented support roller core 1 axially runs through a lubricating oil passage 2, and an oil outlet hole 3 is provided outside the segmented roller core, and the oil outlet hole 3 is connected with the lubricating oil passage 2, and the oil outlet hole 3 is arranged on the same side as the roller The bearing connection position where the core phase is socketed, as shown in Figure 3, the concave platform 10 at the...

Abstract

A segmental supporting mandrel for the rolling roller has an axial lubricating oil channel and two eccentrical ends matched with the baking bearings in eccentrical mode for eliminating the non-uniform deformation of rolling roller.

Description

technical field [0001] The invention relates to a backing roll core, in particular to a segmented support roll core used in a rolling mill. Background technique [0002] In the manufacture and use of plate and strip mills, backing bearing rolls are usually used to support the intermediate support rolls. The existing backing bearing rolls use a through shaft, on which bearings are fixed in sections, and the bearing rolls are The seat direction is embedded in the groove of the convex and concave saddle seat, and is fixedly supported with the saddle seat. [0003] In the prior art, as shown in Figure 11, the original through shaft is divided into multiple sections, and a bearing is installed on each section of the shaft. A concave platform 10 is formed, as shown in FIG. 5 , a groove is formed at the junction of adjacent segmental support roller cores, and a bushing 4 is used to socket together. This kind of roller core is easy to install, flexible to use, easy to replace, and...
