High-speed lubrication engineering plastic ball

Abstract

The invention discloses a high-speed lubrication engineering plastic ball, which is good in lubricating property, low in abrasion, simple in structure and long in service life. The high-speed lubrication engineering plastic ball is characterized by being made of engineering plastics; an axle hole with two through ends is formed by passing through the center of the ball; a cavity used for storing lubricating grease is arranged on the ball at the outer circle of the axle hole; and the cavity is communicated with the axle hole by an oil guide groove. When the high-speed lubrication engineering plastic ball is installed, the lubricating grease is injected into the cavity, a shaft moves in the axle hole, lubrication is continuously provided for a kinematic pair by the lubricating grease in the cavity, and the engineering plastics is also good wear-resistant material. Therefore, the high-speed lubrication engineering plastic ball has the advantages of being simple in structure, reliable in lubrication, light in weight and convenient to maintain, does not need to be injected with lubricating agent frequently, and achieves the combination of self-lubrication and continuous lubrication of the outside lubricating grease under the condition of high-speed motion, thus being mainly suitable for the fields such as micromotor industry, instruments and the like.

Description

technical field [0001] The invention relates to a lubricated mechanical component, in particular to a high-speed lubricating engineering plastic sphere. Background technique [0002] In some mechanisms, such as rocker mechanism, crank slider mechanism, etc., in addition to high-speed rotation, some of the above components also require a certain self-aligning function, so higher requirements are put forward for wear reduction, lubrication and mechanism. The current mechanism design is to separately design the two mechanisms of rotation and self-aligning and then combine them together. Such a structure is complicated and the manufacturing cost is high. Contents of the invention [0003] The main purpose of the present invention is to provide a high-speed lubricating engineering plastic sphere with good lubricating performance, small wear, simple structure and long service life. [0004] In order to meet the above-mentioned requirements, the technical solution of the pre...
