Embodiment Construction

[0070] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0071] Such as Figure 1 to Figure 12 As shown, the four-point contact ball bearing peach-shaped groove trimming processing method, such as Figure 1 to Figure 4 As shown, the four-point contact ball bearing includes an outer ring 1, an inner ring 2 and several steel balls 3, and several steel balls 3 are evenly arranged and arranged in the channel formed by the outer ring 1 and the inner ring 2. Both ends of the contact ball bearing are provided with a sealing ring 4; the outer ring 1 is an integral structure, the channel of the outer ring 1 is a peach-shaped channel, the radius of curvature of the peach-shaped channel is R, and the steel ball 3 The contact angle α with the groove is 25°, the contact angle is the angle between the normal line of the contact point of the steel ball 3 and the in...

Abstract

The invention relates to a finishing machining method for a peach-shaped groove of a four-point contact ball bearing, and belongs to the technical field of bearing machining. A lathe bed, a grinding wheel axial moving device, a grinding wheel dresser, a product clamping device and a PLC touch screen are included. The finishing machining method comprises the steps of carrying out primary finishing on a common grinding wheel by using a diamond pen of the grinding wheel dresser, and determining that the curvature radius of the grinding wheel is completely matched with the design requirement; according to the curvature radius of a peach-shaped groove, calculating the curvature center distance of groove arcs on the two sides of the peach-shaped groove, and then determining a point Oa and a point Ob at the curvature center positions of the groove arcs on the two sides of the peach-shaped groove on the PLC touch screen; and through horizontal movement of a servo mechanism, accurately controlling the axial movement distance of the grinding wheel, and according to the equipment adjusting requirement in the primary finishing process of the grinding wheel dresser, carrying out continuous secondary segmented finishing on the shapes of the two sides of the grinding wheel to form a peach-shaped structure. The finishing machining method for the peach-shaped groove of the four-point contact ball bearing has the beneficial effects of being simple, convenient, high in precision and high in applicability.

Description

technical field [0001] The invention relates to a repairing and processing method for a four-point contact ball bearing, in particular to a repairing and processing method for a peach-shaped groove of a four-point contact ball bearing, and belongs to the technical field of bearing processing. Background technique [0002] At present, the grinding of peach-shaped grooves of four-point contact ball bearings mainly relies on diamond rollers to repair the peach-shaped grooves of the grinding wheel. For example, the publication number is CN 103522189 A, and the application number is 2012104067815. The patent application for the method discloses such a technical solution: the circular arc dresser adopts a simply supported beam structure supported at both ends, and the straight line The movement is converted into a rotary motion, which drives the rotating bracket to swing back and forth regularly, and at the same time makes the diamond pen fixed on the rotating bracket swing recipr...
