Self-lubricating high-thrust bearing

Abstract

The invention provides a self-lubricating high-thrust bearing which is composed of an upper round thrust plate, a lower round thrust plate and a retainer clamped between the upper thrust plate and the lower thrust plate, wherein the retainer is provided with balls; the retainer is formed by buckling an upper round rack plate and a lower round rack plate and connecting the upper round rack plate and the lower rack plate into a whole by virtue of multiple sunk screws; multiple single-row or multi-row conical holes are formed in the upper round rack plate and lower round rack plate of the retainer along the circumferential direction at equal intervals, so that multiple cavities are formed along the circumferential direction; each cavity is internally provided with one ball; the balls are contacted with the upper round thrust plate and the lower round thrust plate; the thrust plates are made of a POM (Polyoxymethylene) material or a stainless steel material; the retainer is made of a nylon material; the balls are made of the POM material; a clearance is reserved between each ball and the corresponding cavity. The self-lubricating high-thrust bearing is simple in structure, convenient to assemble, high in compression resistance, high in carrying capacity and especially applicable to seawater and salt mist corrosive environments, and has the self-lubricating, corrosion-resistant, and wear-proof effects.

Description

technical field [0001] The invention relates to a bearing, in particular to a large-thrust bearing with light weight, good corrosion resistance and self-lubrication, which is suitable for use in marine energy generating devices such as coastal wind energy, tidal current energy, and wave energy. Background technique [0002] At present, the international energy crisis and continuous environmental deterioration have made countries intensify their efforts to develop new renewable energy sources. Ocean energy has broad application prospects and commercial prospects due to its huge reserves. The bearing group is an important part of ocean energy power generation devices such as coastal wind energy, ocean tidal energy, and wave energy. The traditional bearing set is composed of balls and rollers made of metal materials. It is difficult to work reliably for a long time in working environments such as sea salt spray corrosion and seawater immersion electrochemical corrosion, and req...

AI Technical Summary

Problems solved by technology

The traditional bearing set is composed of balls and rollers made of metal materials. It is difficult to work reliably for a long time in working environments such as sea salt spray corrosion and seawater immersion electrochemical corrosion, and requires lubricating oil lubrication and maintenance. Ceramic bearings and other non-woven bearings Metal bearing groups are difficult to withstand large load impacts, etc., so a new type of bearing group that can work reliably in marine salt spray environments or direct seawater immersion environments is needed
