Abstract
A radial thrust bearing 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 that of the outer annular thrust plate but larger than that of the inner annular thrust plate. The radial thrust bearing is characterized in that the annular holder is at least provided with at least one column of hole sites which are arranged in the circumference direction and used for containing the balls, and the distances between every two adjacent hole sites in each column are equal; when the annular holder is provided with a plurality of columns of hole sites, hole centers of the adjacent hole sites in every two adjacent columns of hole sites are staggered in the axial direction; each hole site of the annular holder is internally provided with the corresponding POM balls, the annular holder provided with the POM balls is arranged between the outer annular thrust plate and the inner annular thrust plate, the POM balls arranged 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, and rolling fit is achieved. The radial thrust bearing is simple in structure, large in bearing force and good in corrosion resistance.
Description
Technical field
The present invention relates to a kind of bearing, particularly relate to a kind of radial-thrust bearing, be 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.The ball that traditional bearing group is manufactured by metallic material, roller etc. form, under the working environments such as electrochemical corrosion of sea salt spray corrosion, sea water immersion, be difficult to long-time reliably working, and need oil lubrication and maintenance, therefore and the nonmetallic bearing groups such as ceramic bearing are difficult to bear large load impact etc., need a kind ofly novel can directly soak the bearing pack that environment can reliably working at ocean salt mist environment or seawater.
Summary of the invention
Object of the present invention, 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 radial-thrust bearing, comprises outer ring thrust plate, interior annular thrust plate, annular retainer and a plurality of 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 comprised of outer ring frame plate and interior annular frame plate.On outer ring frame plate along the circumferential direction, and equidistant a plurality of external conical shape hole that is provided with.On interior annular frame plate, along the circumferential direction, and be equidistantly provided with a plurality of internal tapered holes.A plurality of external conical shape hole of offering on outer ring frame plate is quantitatively identical with a plurality of 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 a plurality of cavitys, a ball of installing in each cavity, outer ring frame plate is fixedly connected with by a plurality of sunk screws with interior annular frame plate.
Advantage of the present invention:
The present invention 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 present invention has obvious economy and social value.
