The utility model discloses a realize through following technical scheme:
the utility model provides a thrust bearing lubricating structure for twenty roller mills of sendzimir, includes bearing frame, thrust bearing, round pin axle and clamp plate, thrust bearing fixes at the bearing frame, bearing frame and thrust bearing pass through the round pin hub connection, the top of two side arms of bearing frame is equipped with the clamp plate, the clamp plate passes through the screw and is connected with the bearing frame.
Furthermore, the bearing seat comprises a base and two raised side arms which are integrally formed, the cross section of the base is rectangular, 6 through holes are formed in the base, two threaded holes are formed in the upper end face and the lower end face of each side arm respectively, and the threaded holes are used for fixing the pressing plate and correspond to the through holes in the pressing plate.
Furthermore, the clamp plate is equipped with two through-holes for last, the size of clamp plate is the same with the size of bearing frame side arm section.
Furthermore, an oil inlet channel is machined in the center of the axial direction of the pin shaft on one side, an oil outlet channel is machined in the position, corresponding to the center of the thrust bearing, of the radial direction of the pin shaft, and the oil outlet channel is intersected with the oil inlet channel.
Furthermore, the depth of the oil inlet channel is 85-105mm, and the diameter of the oil inlet channel is smaller than the width of the pin shaft.
Furthermore, the diameter of the oil outlet channel is 2-4 mm.
Further, the oil inlet channel is externally connected with an oil-gas lubricating device.
The utility model has the advantages that: through the technical design of the thrust bearing lubricating structure, the long-term stable operation of the thrust bearing stopping of the intermediate transverse moving device of the Sendzimir twenty-high rolling mill is met, meanwhile, the problem that the transverse moving precision of the first intermediate roll is lost due to the damage of the thrust bearing can be solved through the novel lubricating structure, the surface quality defect of the steel strip in the rolling process due to the loss of the transverse moving precision is avoided, and the aims of improving the production efficiency of equipment and reducing the production cost are finally achieved.
