Application of Crossed Roller Bearing on Rotary Table of Machine Tool
As an important part of the machinery equipment industry, the machine tool industry plays a pivotal role in the development of the entire national economy. Therefore, the development level of the machine tool industry is usually a sign of the overall industrial development level. With the increasing development of modern manufacturing, modern machine tools are developing in the direction of "high speed, precision, compound and intelligence". The proportion of CNC machine tools is gradually increasing. In the field of CNC, the proportion of high-end CNC machine tools (such as heavy-duty machine tools, intelligent machine tools, etc.) is also increasing. Rotary tables are widely used in various CNC milling machines, boring machines, various vertical turning machines, milling and other machine tools. In addition to the requirement that the rotary table can bear the weight of the workpiece well, it is also necessary to ensure its rotation accuracy under load.
As the core component of the rotary table, the crossed roller bearing must not only have a high load-bearing capacity during the operation of the rotary table, but also have high rotation accuracy, high anti-overturning ability, and high speed capability. The characteristic of the crossed roller bearing is that there are two raceways in the bearing and the rollers arranged in a cross. Compared with the traditional thrust bearing + radial centering bearing combination, the crossed roller bearing has a compact structure, a small volume, and simplifies the design of the table, thereby reducing the cost of the rotary table. TEDIN accumulated rich experience in the application of crossed roller bearings on the rotary table of machine tools. With reference to similar foreign products and combined with its own characteristics, it has developed a series of crossed rollers suitable for application in the rotary table of machine tools.
Due to the use of optimized pre-tightening force, our crossed roller bearing has a high rigidity, so the rigidity and accuracy of the rotary table are also guaranteed. Our company's crossed roller bearings have: high operating accuracy; strong anti-overturning ability; reduced axial length and processing costs, limited changes in geometric dimensions caused by thermal expansion; nylon separator, low moment of inertia, low starting torque; optimized preload, High rigidity, small runout; line contact, high rigidity, high guide roller running accuracy; carburized steel provides excellent impact resistance and surface wear resistance; simple but sufficient lubrication.
When the bearing is installed, the crossed roller bearing has already applied the pre-tightening force at the factory, and there is no need to have a complicated installation and adjustment process like a hydrostatic bearing. The installation of crossed roller bearings is simple, and it is easy to adjust the original installation form or maintenance method. Crossed roller bearings are suitable for various types of vertical or horizontal boring machines, as well as vertical grinding, vertical turning and large gear milling machines.
