Abstract

The invention discloses a high-precision and high-rigidity radial-axial combined bearing which mainly consists of a housing washer, a first shaft washer, a second shaft washer, lower-row axial rollers, upper-row axial rollers, a self-locking screw, a lower-row retainer, an upper-row retainer and radial rollers; the first shaft washer and the second shaft washer are connected into a whole body by the self-locking screw to form two axial race surfaces and a radial race surface; the housing washer is provided with three race surfaces, an axial lower race surface is connected with the first shaft washer by the lower-row axial rollers, an axial upper race surface is connected with the second shaft washer by the upper-row axial rollers, and a radial race surface of the housing washer is connected with the first shaft washer by the radial rollers; the lower-row axial rollers are connected with the lower-row retainer, and the upper-row axial rollers are connected with the upper-row retainer. The radial-axial combined bearing has the beneficial effects of meeting the axial and radial high-rigidity requirements of the bearing, and meeting the requirements of the product for low friction and high lubrication.

Description

technical field [0001] The invention relates to the field of machine tools such as precision numerical control milling machines, boring machines, and machining centers, and in particular to high-precision, high-rigidity shaft-radial combination bearings. Background technique [0002] With the continuous development of my country's machine tool industry, especially the continuous update of the machine tool structure, the accuracy requirements of some precision CNC milling machines, boring machines, machining centers and other workbenches are getting higher and higher, and the old structure bearings supporting the precision workbench are difficult to meet the machine tool requirements High precision, low friction, high rigidity requirements. [0003] Aiming at the requirements of precision workbenches, it is urgent to provide a new type of combined bearing, which can overcome the shortcomings of the old structure products and meet the needs of the field of precision machine too...
