Machining method for aviation high-precision bearing roller

Abstract

The invention discloses a method for processing aviation high-precision bearing rollers, which is characterized in that a clamping position is set at the end of the roller, a swinging part is set on the workbench, the roller is installed on the swinging part through the clamping position, and the swinging part The rotation makes the roller axially inclined, and the rotation direction of the grinding wheel always coincides with the normal direction at the grinding point of the sinking contour of the roller, ensuring that the grinding wheel and the roller are always in point contact. In the method for processing aviation high-precision bearing rollers described in the present invention, a clamping position is set at the end of the roller, which is convenient for clamping the roller to make it tilt and rotate, and the grinding wheel and the surface of the roller are ground by point contact, and the grinding force And the grinding heat is small, the force of the grinding wheel is consistent, the deformation is consistent, the machining accuracy is effectively improved, and the error distribution on the surface of the roller is evenly distributed to ensure that the roller has a good balance when it rotates at a high speed.

Description

technical field [0001] The invention relates to the technical field of machining grinding methods, in particular to a machining method for aviation high-precision bearing rollers. Background technique [0002] Roller bearings are widely used in aviation equipment. In order to improve the axial bearing capacity of bearings, eliminate stress concentration, reduce wear, and improve the stability of operation, more and more rollers with chamfered sinking at both ends are used. However, the chamfers at both ends of the roller sink into irregular curved surfaces, and the precision required for the roller is high, and the processing is difficult. The traditional method of processing rollers is to use a forming grinding wheel for profiling grinding. The forming grinding wheel is pre-set with the same contour groove as the required roller shape, and then the roller with a straight cylindrical structure is ground on the forming grinding wheel. , so that the surface of the roller form...

Problems solved by technology

[0003] The technical problem to be solved and the technical task proposed by the present invention are to improve the existing technology, provide a kind of aviation high-precision bearing roller processing method, and solve the problem of poor contour shape and precision of the traditional grinding wheel in the current technology. Low, difficult to control the amount of wear, short service life, and the problem that the size deviation of the rollers increases with the use of the forming grinding wheel.
