Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] The invention provides a device for coating the surface of a ball, wherein the device is in a vacuum chamber.

[0021] see figure 1 , the ball surface coating device of a preferred embodiment of the present invention includes a rotating shaft 4, a tooling frame 11, a target source 7, an ion source 8 and a transmission device 9;

[0022] The tooling frame is composed of a fixed plate 5, a fixed rod 6, a rotating shaft 4 and a plurality of rotating assemblies; wherein, each rotating assembly is composed of an upper rotating disk 3 and a lower rotating disk 1, and the upper rotating disk 3 and the lower rotating disk 1 are on the opposite surfaces. A circle of annular groove is processed; the structure of the annular groove can not only play a limiting role, but also reduce the probability of adhesion between the ball and large particles due to the re...

Abstract

The invention discloses a device for ball surface coating. The device adopts the scheme that an upper rotating disc is fixed with a fixed bracket through a spacing hole, and a lower rotating disc is connected with a rotating shaft, namely, the lower rotating disc rotates, and the upper rotating disc is fixed, so that the distances from the surfaces of balls to the rotating center of the rotating shaft are different, the balls can rotate automatically, a coating material in rectilinear propagation can be uniformly deposited on the surfaces of the balls, and the films of the surfaces of the balls are more uniform.

Description

technical field [0001] The invention relates to the field of ball coating, in particular to a device for coating the surface of a ball. Background technique [0002] The development of bearings in the direction of high precision and long life has put forward higher requirements for the wear resistance of balls and grooves, especially oil-free bearings and low-speed oil-lubricated bearings have more obvious requirements for wear resistance, which requires preparation Features high hardness bearing tracks and balls. [0003] When coating the surface of the ball, due to the shadow effect, the uniformity of the film layer on the surface of the ball has always been an engineering problem. At present, some coating methods have been proposed in China, such as placing the ball in a tray. During the coating process, the two ends of the tray are made High and low relative motion, the ball rolls in the tray through the action of gravity, so as to achieve uniform coating. However, dur...
