Production process of paraffin-based self-lubricating bearing

Abstract

The invention discloses a production process of a paraffin-based self-lubricating bearing. The production process comprises the following steps: S1, processing a plurality of lubricant holes along theradial direction of the self-lubricating bearing, wherein the ends, facing the axis of the self-lubricating bearing, of the lubricant holes are opened and the ends, opposite to the axis of the self-lubricating bearing, of the lubricant holes are closed; S2, preparing a paraffin solid lubricant and heating the paraffin solid lubricant till the paraffin solid lubricant is of flowability; S3, heating the self-lubricating bearing, and filling the lubricant holes with the paraffin solid lubricant with flowability from the lubricant holes to the end of the axis of the self-lubricating bearing through a pressure conveying pipeline; and S4, cooling the self-lubricating bearing and the paraffin solid lubricant, wherein the paraffin solid lubricant is solidified. According to the production process, the solid lubricant can fill the holes of the bearing through a mechanical operation, so that the production efficiency is high and the labor intensity is low. The degree of packing and the fillingamount of the solid lubricant in each hole can be controlled accurately.

Description

Technical field [0001] The invention relates to the technical field of a self-lubricating bearing processing technology, in particular to a paraffin-based self-lubricating bearing production technology. Background technique [0002] Solid lubricants for bearings are a composite material used in self-lubricating bearings. Usually, solid lubricants are filled in the cavities of the bearing. During the operation of the bearing, the solid lubricant can slowly migrate from the cavities to the bearing and the rotating shaft. Or it is the contact surface of the bearing and the bearing seat, thereby forming a lubrication effect, reducing the wear and running resistance of the bearing. [0003] A kind of PTFE self-lubricating axial limit alloy bearing described in Chinese Patent Document CN 106545582 A is a kind of self-lubricating bearing that can be used in water environment provided earlier by the applicant of the present invention. A solid lubricant includes the following components in...

Problems solved by technology

The above-mentioned solid lubricant is mainly filled into the holes of the bearing by manual means. The above-mentioned operation method is not only low in production efficiency and labor-intensive, but also difficult to accurately control the filling compactness and filling amount of the solid lubricant in each hole, thus As a result, there are large inter-individual differences in the use of self-lubricating bearing products, which is not conducive to making full use of self-lubricating bearings on the premise of ensuring safe operation
