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, more particularly to a kind of radial-thrust bearing it is adaptable to coastal wind energy, marine tidal-current energy and
Use in the ocean power generating devices such as wave energy.
Background technology
At present, international energy crisis and lasting ecological deterioration make numerous and confused increasing the in various countries that emerging regenerative resource is opened
Degree of having an effect, marine energy is had broad application prospects due to its huge reserves, commercial promise.Bearing group is along Caulis Piperis Kadsurae
Vitals in the ocean power generating devices such as energy, Ocean Tidal Current Energy, wave energy.The rolling that traditional bearing group is manufactured by metal material
Pearl, roller etc. form, and are difficult to reliable work for a long time under the working environments such as sea salt air corrosion, the electrochemical corrosion of sea water immersion
Make, and need oil lubrication and maintenance, and the nonmetallic bearing group such as ceramic bearing is difficult to bear big load impact etc., therefore
Need a kind of new can directly soak, in ocean salt mist environment or sea water, the bearing group that environment is capable of reliably working.
Content of the invention
The purpose of the present invention, is to provide a kind of radial-thrust bearing, structure is simple, bearing capacity is big, corrosion resistance and good.
Employed technical scheme comprise that：
A kind of radial-thrust bearing, including outer annular thrust plate, annular thrust plate, annular retainer and multiple ball,
The diameter of annular retainer is less than outer annular thrust plate diameter, between annular thrust board diameter.It is characterized in that：
On annular retainer, at least string along the circumferential direction arranges, in order to install the hole position of ball, and every string hole
In position, often the distance between two adjacent hole positions are equal.
On annular retainer, when offering multiple row hole position, often the hole heart of the adjacent hole position in adjacent two row hole positions is vertically
Stagger.
It is equiped with POM ball in each hole position on annular retainer.The annular retaining being equiped with POM ball is placed on
Between outer annular thrust plate and annular thrust plate, on annular retainer, the POM ball of installing is supported respectively in outer thrust collar
On the inwall of plate and annular thrust plate, roll cooperation.
Above-mentioned hole position is bellmouth or sphere hole.
Above-mentioned thrust plate is the thrust plate of POM material or stainless steel.
Above-mentioned retainer is nylon cages.
There is gap between above-mentioned ball and corresponding hole position.
The work surface of POM ball guarantees to be on thrust plate.
Above-mentioned retainer is made up of outer annular frame plate and annular frame plate.On outer annular frame plate along the circumferential direction, and equidistantly
From being provided with multiple male-tapered holes.On annular frame plate along the circumferential direction, and equidistant be provided with multiple internal tapered holes.Outer annular frame plate
On multiple male-tapered holes of opening up quantitatively identical with the multiple internal tapered holes opening up on annular frame plate, position is respectively relatively
Should, and shapes and sizes are identical, in opposite direction.Outer annular frame plate is snapped together with annular frame plate, on outer annular frame plate
Male-tapered hole is aligned with the internal tapered hole on annular frame plate, forms one ball of installing in multiple cavitys, each cavity, outward
Annular frame plate is fixedly connected by multiple sunk screws with annular frame plate.
Advantages of the present invention：
Present configuration is simple, easy to assembly, self-lubricating, and corrosion-resistant, wear-resisting and anti-pressure ability is strong, and large carrying capacity is special
It is not applied to and uses under sea water and salt air corrosion environment, as ocean power generating devices such as coastal wind energy, marine tidal-current energy, wave energies
In vitals, be arranged on device needs rotation radial thrust face on, the present invention has obvious economy and social value.
