Increasing the Wear Resistance of a Polymer-Coated Radial Bearing Running on a Micropolar Lubricant

The article is devoted to the analysis of a mathematical model lubricant mootion in working gap radial sliding bearing with support profile having fluoroplast-containing composite polymer coating groove on surface, which has micro-polar properties. New models describing motion material groove, micropolar rheological properties laminar mode motion, approximation for “thin layer”, are proposed. A comparative obtained results theoretical experimental study without and existing ones, confirming real practice, performed. novelty work lies development methodology engineering calculations design presence that allows determining value main tribotechnical parameters: hydrodynamic pressure, load capacity, friction force, coefficient. As result study, significant expansion possibilities applying practice operating lubrication non-Newtonian flow mode, allowing assessment operational characteristics - amount capacity coefficient was achieved. fluoroplastic-containing anti-friction width 2 mm ensured stable ascent shaft wedge, experimentally confirmed correctness studies bearings diameter 40 1…8 wide, at speed 1…3 m/s, 4.2…45.5 MPa.
