Abstract
The utility model is related to a kind of compound scroll wheels of multi-directional ball, belong to General Mechanical Parts field.To overcome the compound scroll wheel installation of general Universal wheel type complex, diameter adjustment range is small, the short disadvantage of service life.The utility model discloses a kind of compound scroll wheel of multi-directional ball for combining multi-directional ball and common idler wheel, realizes and is keeping flexibly turning to and obstacle crossing function, simplifies the structure of compound scroll wheel and extend the service life of combined wheels.Realizing the technical solution of foregoing invention is：Multi-directional ball is evenly distributed on the circumference for being attached to scroll wheel, in this way in normal flat overground locomotion, is carried out rolling Forward and steering by multi-directional ball, then wheel disc rolls obstacle detouring when encountering obstacle.Compound scroll wheel disclosed by the utility model has the advantage that：（1）Structure can be simplified and convenient for assembling;（2）Improve service life.
Description
Technical field
The utility model is related to a kind of scroll wheels, belong to machine component field, and it is compound to relate in particular to a kind of multi-directional ball
Scroll wheel.
Background technology
General compound scroll wheel has direction flexibility and obstacle crossing function, but the installation of universal wheel is complex, and
And since general universal wheel diameter can not be made small, so that the diameter of the compound scroll wheel assembled is very big,
Limit the use scope of compound scroll wheel.
It can either possess flexibly commutation and obstacle crossing function to realize, and the diameter adjustment range and just of bigger can be obtained
In installation and adjustment.The utility model discloses a kind of compound scroll wheel for combining multi-directional ball and common wheel, set
The advantages of the two, realization can either flexibly turn to have prodigious diameter adjustment range again with obstacle detouring and be easily installed tune
It is whole.
Invention content
Realizing the technical solution of above-mentioned utility model is：Multi-directional ball is evenly distributed on the circumference for being attached to scroll wheel, is existed in this way
When normal flat overground locomotion, carried out rolling Forward and steering by multi-directional ball, when encountering obstacle, then wheel disc rolls obstacle detouring.This practicality
Novel particular content is：
A kind of compound scroll wheel of multi-directional ball, by one group of multi-directional ball [1], a wheel disc [2], one group of circlip [3], one
A bearing [4], a fixing piece [5] are constituted, it is characterized in that：The multi-directional ball [1] is distributed on wheel disc [2], wheel disc [2] and
Circlip [3] is coupled by bearing [4] with fixing piece [5]；
The ratio between maximum outside diameter is not more than 1 when wheel disc [2] outside diameter and multi-directional ball [1] are installed to wheel disc [2]:1.5；
The ratio between thickness of multi-directional ball [1] screw top diameter and wheel disc [2] is not more than 1:2；
Multi-directional ball [1] can be mounted directly on the threaded hole of wheel disc [2] by main thread；
Bearing [4] uses Desing of Interference Joint with wheel disc [2]；
The number of multi-directional ball [1] on wheel disc [2] is 6 or more.
Compound scroll wheel disclosed by the utility model has the advantage that：
（1）Structure can be simplified and convenient for assembling；
（2）The diameter adjustment range of bigger can be possessed；
（3）Improve the service life of combined wheels.
Description of the drawings
Fig. 1 is the compound scroll wheel installation diagram of multi-directional ball；
The meaning that each legend label indicates respectively in attached drawing is as follows：
1-multi-directional ball, 2-wheel discs, 3-circlips, 4-bearings, 5-fixing pieces.
Specific implementation mode
1 provide specific embodiment below in conjunction with the accompanying drawings.
One embodiment of the utility model is that eight small multi-directional balls 1 are distributed on wheel disc 2, and bind mode is connected with screw thread
It is connected on the shape wheel disc of all directions.
Another embodiment of the utility model is that ten small multi-directional balls 1 are distributed on ten rectangular wheel discs 2, wheel disc
Ten square structures, the bind modes such as 2 uses are threadedly coupled.
These principles are identical, change the other embodiment that can constitute the utility model on concrete structure.
