Abstract

The invention relates to a composite self-lubricating bearing which comprises a bearing group and a shell, wherein the bearing group is formed by assembling at least one bearing unit, and the bearing unit is provided with an axially-perforative axial hole in which an axial core passes through; the shell is a hollow tube body which is used for sleeving on the outer edge of the bearing group along the axial core direction in a sealing way, and at least one storage tank for storing a lubricating medium is defined by the bearing group and the shell. At least one microgap runner communicated with the axial hole is arranged round the storage tank so as to continuously supply the lubricating medium. The lubricating medium exerts the efficacy of high-quality lubrication between the axial core and the axial hole.

Description

technical field

[0001] The invention relates to a composite self-lubricating bearing, in particular to a composite self-lubricating bearing which can automatically replenish lubricating medium to achieve enhanced grinding effect. Background technique

[0002] In order to make the operation between the bearing and the rotating shaft smooth, and to avoid abnormal friction and heat generation, it is usually necessary to frequently add additional lubricants (lubricant), such as lubricating oil with low viscosity and high viscosity Lubricating grease (gerase) and lubricants containing solid lubricating particles, etc., in order to continuously form a tribology interface (tribology interface) between the inner wall of the shaft hole and the outer wall of the rotating shaft core that is sufficient to carry the load of the shaft core; however, due to frequent Adding additional lubricating medium is not only labor-intensive but also inconvenient. If the lubricating medium is not repl...
