Embodiment Construction
[0029] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations therein are illustrative in nature and not intended to limit the present invention. invention.
[0030] Such as Figure 1 to Figure 4 As shown, an embodiment of the oil film bearing removal tool proposed by the present invention, the oil film bearing removal tool can be used to install or remove the oil film bearing on the roll neck 13 of the roll. In this embodiment, the removal tool mainly includes a cylinder-piston mechanism, a nut 4 and four screw rods 9 . It should be noted that, for ease of understanding, based on the structural basis that the rolls are usually placed horizontally, the direction of the oil film bearing dism...

The invention provides an oil film bearing replacer. The replacer comprises an oil cylinder piston mechanism, a nut and at least one screw, wherein the oil cylinder piston mechanism comprises a cylinder sleeve and a cylinder body, and the cylinder body is provided with a first end part and a second end part; the first end part is arranged in the cylinder sleeve in a scalable way, and the second end part extends out of the cylinder sleeve and can be detachably fixed to the end part of a roll neck; the cylinder body and the cylinder sleeve can do piston motion; the nut is screwed to the periphery of the cylinder sleeve, and the screw is provided with a first end part and a second end part; the first end part is adjustably screwed to the nut, and the second end part is detachably screwed to a bearing box assembly of an oil film bearing. The designed structure of the oil film bearing replacer is used as a device for replacing the oil film bearing but is not the component of an oil film bearing assembly, so that the oil film bearing replacer can be used only in the replacing process. The oil film bearing replacer has the advantages of being compact in structure, convenient to operate, precise in replacing, efficient and safe and low in using cost.
Description
technical field [0001] The invention relates to the technical field of oil film bearings, in particular to an oil film bearing dismounting tool for pushing and pulling an oil film bearing assembly to attach or detach from a roll neck. Background technique [0002] Existing strip rolling mills use screw drive or hydraulic drive devices to fit the oil film bearings and bearing housings together or separate them from the installation position of the roll neck. Usually, threaded or hydraulic driving device is used as an important part of the oil film bearing assembly to realize the disassembly and assembly of the oil film bearing. [0003] When using the screw drive device for disassembly and assembly, it is necessary to use the driving to pull the steel wire rope to push the oil film bearing assembly and the bearing seat to fit or separate from the roll. The safety of the steel wire rope must be checked before operation, and there are certain safety hazards. The operation proce...
