Problems solved by technology

[0002] On large-scale lifting equipment, if a certain mechanism of the crane is driven by two electric motors respectively, and the two reducers are required to be rigidly synchronized but far apart, it is necessary to use a universal joint to connect the two reducers. A certain output shaft of the reducer is connected; or one end is the driving end and the other end is the driven end. Rigid synchronization is also required, and the use of universal joints is also required. During the use of universal joints, dry grinding and Wear, causing the shaft head to move or skew in the axial and longitudinal directions

Abstract

The invention discloses a wear-resistant coating for a universal joint. The wear-resistant coating is characterized by consisting of the following components in parts by mass: 12-17 parts of a vinyl polyacrylate emulsion, 3-7 parts of antimony-doped tin oxide nanocrystals, 6-10 parts of ethyl acetate, 20-30 parts of zinc borate modified phenolic resin, 1-4 parts of methylbenzene, 2-5 parts of a filler, 10-15 parts of polydimethylsiloxane, 3-7 parts of graphite powder, 2-4 parts of polyacrylic acid, 11-16 parts of diethyl-o-phthalate, 4-8 parts of cellulose hydroxypropyl methyl ether, 2-4 parts of a nano solution, 3-6 parts of adjuvants, 2-4 parts of a coupling agent and 1-3 parts of a curing agent. The wear-resistant coating provided by the invention is high in strength, wear-resistant and long in service life.

Description

technical field [0001] The invention relates to a coating, in particular to a wear-resistant coating for universal joints. Background technique [0002] On large-scale lifting equipment, if a certain mechanism of the crane is driven by two electric motors respectively, and the two reducers are required to be rigidly synchronized but far apart, it is necessary to use a universal joint to connect the two reducers. A certain output shaft of the reducer is connected; or one end is the driving end and the other end is the driven end. Rigid synchronization is also required, and the use of universal joints is also required. During the use of universal joints, dry grinding and Wear, causing the shaft head to move or skew in the axial and longitudinal directions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coating for universal joints with high strength, long service life and wear resistance in view of the above sh...
