Embodiment Construction
[0013] like figure 1 As shown, the present invention provides a straightening machine supporting roller combination structure, which is mainly composed of a needle bearing assembly, a thrust bearing assembly and a lubrication system, and the thrust bearing assembly, an end cover, and a needle bearing assembly form a multiple sealing structure. Its needle roller bearing assembly is composed of shaft 1, shaft sleeve 2, needle roller cage 3 and needle roller. The needle roller is installed between shaft 1 and shaft sleeve 2 through needle roller cage 3; its thrust bearing assembly is composed of thrust ring I4, Thrust ring II6, steel ball cage 5 and steel balls are composed. Thrust ring I4 is fixedly installed in the slot on the shaft sleeve 2 of the needle roller bearing assembly through tight fit, and thrust ring II6 is installed on shaft 1 of the needle roller bearing assembly. , the steel ball is installed between the thrust ring I4 and the thrust ring II6 through the steel b...

The invention relates to the technical field for the design and manufacturing of a supporting bearing for a straightener, in particular to a combined structure of supporting trolleys for a straightener, which is essentially composed of a needle roller bearing component, a thrust bearing component and a lubricating system. The needle roller component is composed of a shaft (1), a sleeve (2), a needle roller retainer (3) and a quill roller; the thrust bearing component is composed of a thrust ring I (4), a thrust ring II (6), a steel ball retainer (5) and steel balls; the lubricating system comprises a central blind hole which is made at one end of the shaft of the needle roller bearing component and is communicated with a radial hole corresponding to the quill roller, a multi-sealed structure consisting of a press-fit type forced filling oil cup (9) thrust bearing component, an end cover and the needle roller bearing component is fixedly connected at the end of the central blind hole; by optimizing, self lubrication through multiplex sealing and axial / radial oil passage are adopted, thereby the revolution accuracy and the technical requirements are guaranteed, and the accurate supporting requirements of a high precision aluminum strip / foil bending straightening unit are met.
Description
technical field [0001] The invention relates to the technical field of support bearings for straightening machines, in particular to a combined structure of support rollers for straightening machines. Background technique [0002] The high-precision aluminum strip and foil stretch bending straightening unit is the key equipment for strip finishing and straightening, and is also the most effective equipment for improving the shape and surface quality of the strip. It was developed rapidly abroad in the 1960s and is now more popular. . At present, the combined structure of supporting rollers for domestic high-precision aluminum strip and foil stretch-bending straightening machines is mainly produced by the German company INA. In order to reduce costs, all enterprises are looking for localized equipment. The combined structure of supporting rollers for high-precision aluminum strip and foil stretch-bending straightening machines developed by this project has high requirements ...
