Abstract

The invention provides a self-lubricating material for a joint robot and a preparation method thereof. The self-lubricating material is prepared from, by weight, 12-18 parts of iron powder, 3-8 partsof Al powder, 10-16 parts of copper sulfide powder, 6-11 parts of graphite, 1-6 parts of calcium hydroxide, 5-13 parts of nano molybdenum disulfide, 2-6 parts of silicon oxide, 2-8 parts of halloysitenanotubes and 12-18 parts paraffin. Compared with the prior art, the iron powder, the Al powder, the copper sulfide powder, the graphite, the calcium hydroxide, the nano molybdenum disulfide, the silicon oxide, the halloysite nanotubes and the paraffin are adopted as raw materials. Through interaction and mutual effects of all the components, the strength of the prepared self-lubricating materialis improved, friction damping is small, and the self-lubricating material is suitable for the joint robot.

Description

technical field [0001] The invention relates to the technical field of lubricating materials, in particular to a self-lubricating material for joint robots and a preparation method thereof. Background technique [0002] Jointed robot, also known as jointed arm robot or jointed mechanical arm, is one of the most common forms of industrial robots in today's industrial field, and is suitable for mechanical automation operations in many industrial fields. There are two types of swing directions for articulated robots: vertical and horizontal. Therefore, this type of robot can be divided into vertical robots and horizontal articulated robots. [0003] Joint robots need self-lubricating materials. Traditional self-lubricating materials have large frictional damping and small operating range, which affects the service life of joint robots. In the prior art, self-lubricating materials and their preparation methods have been widely reported. For example, Chinese patent literature wi...
