Abstract
The invention discloses a kind of iso-curvature door leaf ball bearing wheels, including door leaf and fixed backing, the bottom end both sides of the door leaf are respectively equipped with fixed plate, the lower end of the fixed plate and the top of housing connect, the housing is internally provided with fixed backing, and the fixed backing is internally provided with arc groove, and the inside engaging of the arc groove has steel ball, the lower end of the steel ball is equipped with spin, and the bottom end of the spin is placed in the outside of housing.This kind of iso-curvature door leaf ball bearing wheel, using the design of " iso-curvature ", solve the problems, such as that ball bearing axial load scarce capacity and ball bearing radial capacity are insufficient simultaneously, be conducive to make object it is straight on spin, rotation flexibly, its is simple in structure, manufacture is easy, easy to use.
Description
Technical field
The present invention relates to rolling equipment technical field, specially a kind of iso-curvature door leaf ball bearing wheel.
Background technology
Ball bearing wheel is widely used, but the ball bearing wheel having is being held in the industry-by-industry in society now
When wheel load weight is bigger, bearing wheel is easily damaged, so as to affect the rotation of ball bearing wheel, some ball bearing wheels
In use, sundries is easily accessible in bearing wheel, be easy to cause bearing wheel blocking phenomenon.
Invention content
The purpose of the present invention is to provide a kind of iso-curvature door leaf ball bearing wheel, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the present invention provides following technical solution：A kind of iso-curvature door leaf ball bearing wheel, including door
Fan and fixed backing, the bottom end both sides of the door leaf are respectively equipped with fixed plate, and the lower end of the fixed plate and the top of housing connect
It connects, the housing is internally provided with fixed backing, and the fixed backing is internally provided with arc groove, the inside card of the arc groove
Conjunction has steel ball, and the lower end of the steel ball is equipped with spin, and the bottom end of the spin is placed in the outside of housing.
Further, the housing is fixedly connected with fixed backing by fixing bolt, and the door leaf passes through with fixed plate
Pin is fixedly connected.
Further, the radius of curvature of raceway is formed when the spin is contacted with steel ball rolling as R, the steel ball it is straight
Diameter is Dw, and the condition that when spin is contacted with steel ball rolling meets is 0.510Dw>R>0.5Dw.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of iso-curvature door leaf ball bearing wheel, using " waiting songs
The design of rate ", while solve the problems, such as that ball bearing axial load scarce capacity and ball bearing radial capacity are insufficient, have
Conducive to make object it is straight on spin, rotation flexibly, its is simple in structure, manufacture is easy, easy to use.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
In reference numeral：1- fixing bolts；2- fixes backing；3- housings；4- steel balls；5- spin；6- pins；7- is fixed

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：A kind of iso-curvature door leaf ball bearing wheel, including 9 He of door leaf
Fixed backing 2, the bottom end both sides of the door leaf 9 are respectively equipped with fixed plate 7, and the lower end of the fixed plate 7 connects with the top of housing 3
It connects, the housing 3 is internally provided with fixed backing 2, and the fixed backing 2 is internally provided with arc groove 8, the arc groove 8
Inside engaging has steel ball 4, and the lower end of the steel ball 4 is equipped with spin 5, and the bottom end of the spin 5 is placed in the outside of housing 3.
Further, the housing 3 is fixedly connected with fixed backing 2 by fixing bolt 1, the door leaf 9 and fixed plate 7
It is fixedly connected by pin 6.
Further, the radius of curvature that raceway is formed when the spin 5 and steel ball 4 are in rolling contact is R, the steel ball 4
A diameter of Dw, and the condition that when spin 5 and steel ball 4 are in rolling contact meets is 0.510Dw>R>0.5Dw.
Operation principle：First by fixed plate 7 by pin 6 be fixed on 9 bottom of door leaf, then by housing 3 by passing through
Fixing bolt 1 is fixed with fixed plate 7, and when turning door leaf 9, with steel ball 4 rolling friction, spin 5 can occur for spin 5
The radius of curvature of raceway is formed when being in rolling contact with steel ball 4 as R, a diameter of Dw of steel ball 4, spin 5 is in rolling contact with steel ball 4
When the condition that meets be 0.510Dw>R>0.5Dw, just realizes the design of " iso-curvature " in this way, while solves 5 bearing of spin
The problem of axial load scarce capacity and insufficient ball bearing radial capacity, is conducive to make object straight on spin 5, turns
It is dynamic flexible.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
