Abstract
The utility model discloses a radial thrust bearing which comprises an outer annular thrust plate, an inner annular thrust plate, an annular holder and a plurality of balls. The diameter of the annular holder is smaller than the diameter of the outer annular thrust plate and larger than the diameter of the inner annular thrust plate. The radial thrust bearing is characterized in that at least a line of hole positions formed in the circumferential direction and used for containing the balls are formed in the annular holder, and the distances between the adjacent hole positions in each line of hole positions are equal; when multiple lines of hole positions are formed in the annular holder, the hole centers of the adjacent hole positions in the adjacent lines of hole positions are axially stagger; the POM balls are installed in the hole positions of the annular holder respectively, the annular holder provided with the POM balls is arranged between the outer annular thrust plate and the inner annular thrust plate, and the POM balls installed on the annular holder abut against the inner wall of the outer annular thrust plate and the inner wall of the inner annular thrust plate in a rolling fit mode respectively. The radial thrust bearing is simple in structure, large in bearing force and good in corrosion resistance.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of radial-thrust bearing, is applicable to use in the ocean power generating devices such as coastal wind energy, marine tidal-current energy and wave energy.
Background technique
At present, international energy crisis and lasting environmental deterioration make various countries strengthen one after another the exploitation dynamics to emerging renewable energy sources, and marine energy is because its huge reserves have broad application prospects, commercial promise.Bearing pack is the vitals in the ocean power generating devices such as coastal wind energy, Ocean Tidal Current Energy, wave energy.Ball, roller etc. that traditional bearing group is manufactured by metallic material form, under the working environments such as the electrochemical corrosion of sea salt spray corrosion, sea water immersion, be difficult to long-time reliably working, and need oil lubrication and maintenance, and the nonmetallic bearing groups such as ceramic bearing are difficult to bear large load impact etc., therefore need a kind ofly novel can directly soak the bearing pack that environment can reliably working at ocean salt mist environment or seawater.
Model utility content
The purpose of this utility model, is to provide a kind of radial-thrust bearing, and simple in structure, bearing capacity is large, corrosion resistance and good.
The technological scheme adopting is:
A kind of radial-thrust bearing, comprises outer ring thrust plate, interior annular thrust plate, annular retainer and multiple ball, and the diameter of annular retainer is less than outer ring thrust plate diameter, is greater than between interior annular thrust plate diameter.It is characterized in that:
On annular retainer, have at least row along the circumferential direction to arrange, in order to install the position, hole of ball, and each row Kong Weizhong, the distance between every adjacent position, two holes equates.
On annular retainer, while offering position, multiple row hole, the hole heart of the adjacent holes position of every adjacent two row Kong Weizhong staggers vertically.
In each position, hole on annular retainer, be equiped with POM ball.The annular retaining that is equiped with POM ball is placed between outer ring thrust plate and interior annular thrust plate, and the POM ball of installing on annular retainer is supported respectively on the inwall of outer ring thrust plate and interior annular thrust plate, rolls and coordinates.
Above-mentioned Kong Weiwei cone shape hole or sphere hole.
Above-mentioned thrust plate is the thrust plate of POM material or stainless steel.
Above-mentioned retainer is nylon cages.
Gapped between above-mentioned ball and corresponding position, hole.
The working surface of POM ball is guaranteed on thrust plate.
Above-mentioned retainer is made up of outer ring frame plate and interior annular frame plate.On outer ring frame plate along the circumferential direction, and equidistant multiple external conical shape hole that is provided with.On interior annular frame plate, along the circumferential direction, and be equidistantly provided with multiple internal tapered holes.Multiple external conical shape hole of offering on outer ring frame plate is quantitatively identical with multiple internal tapered holes of offering on interior annular frame plate, and position is corresponding respectively, and shape is identical with size, opposite direction.Outer ring frame plate and interior annular frame plate snap together, internal tapered hole on external conical shape hole on outer ring frame plate and interior annular frame plate aligns, form multiple cavitys, a ball of installing in each cavity, outer ring frame plate is fixedly connected with by multiple sunk screws with interior annular frame plate.
Advantage of the present utility model:
The utility model is simple in structure, easy to assembly, selflubricating, corrosion-resistant, wear-resisting and anti-pressure ability is strong, bearing capacity is large, be specially adapted to use under seawater and salt spray corrosion environment, as the vitals in the ocean power generating devices such as coastal wind energy, marine tidal-current energy, wave energy, be arranged on the rotation radial thrust face of device needs, the utlity model has obvious economy and social value.
