Technical Field
[0001] The utility model relates to the technical field of continuous casting machines, in particular to a spiral roller bearing for continuous casting machines. Background Art
[0002] The rolling system of spiral roller bearings uses spiral rollers wound with steel strips. Therefore, they are called spiral roller bearings. This type of bearing has greater elasticity and radial clearance, can withstand greater impact radial loads, cannot withstand axial loads, and has a low limit speed. It is only suitable for components with low rotation accuracy and often have greater impact loads. When the bearing is installed, the inner ring axis and the outer ring axis are allowed to be tilted by 0.5°. Due to the elastic deformation of this type of bearing, the accuracy cannot be guaranteed during operation, so the accuracy of spiral roller bearings is only ordinary grade, and there is no other precision grade. The inner and outer rings of the bearings are rolled from alloy steel strips and assembled through special processing. The spiral gaps on the surfaces of the inner and outer rings of the bearings can allow the lubricating oil to be continuously and evenly distributed on the working surface of the bearing. When the bearing works under working conditions with a large temperature difference, the bearing matching size can be automatically compensated. The inner and outer rings of the bearings are rolled from alloy steel strips and assembled through special processing. The spiral gaps on the surfaces of the inner and outer rings of the bearings can allow the lubricating oil to be continuously and evenly distributed on the working surface of the bearing. When the bearing works under working conditions with a large temperature difference, the bearing matching size can be automatically compensated. P&N is mainly engaged in the design and production of bearings for plate guide rollers, and each part of the arc casting machinery requires bearing design.
