Abstract
The utility model relates to a universal wheel comprising a universal wheel body. The universal wheel is characterized in that the outer surface of the universal wheel body is provided with a wear-resistant coating. The universal wheel body is provided with a central hole (1) at the center. The universal wheel body is provided with seven trapezoidal openings (2) on the periphery of the central hole (1) in the annular direction. The distance between every two adjacent trapezoidal openings (2) is 3-5mm. The four corners of each trapezoidal opening (2) are provided with chamfers with the radius of 2-5mm. The universal wheel has the advantages of lightness, high strength and long service life.
Description
Technical field
The utility model relates to a kind of cardan wheel.
Background technology
Cardan wheel is exactly so-called movable castor, and its structure allows horizontal 360-degree rotation.Castor is a general designation, comprises movable castor and rigid castors.Rigid castors does not have rotational structure, and can not horizontally rotate can only vertical rotation.These two kinds of castors are all generally collocation use, and such as the structure of hand barrow is two, front tight pulley, back is two movable cardan wheels near what promote handrail.Traditional cardan wheel has the shortcoming that weight is large, intensity is lower, service life is lower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of lightweight, high strength, high service life cardan wheel.
The purpose of this utility model is achieved in that
A kind of cardan wheel, it comprises cardan wheel body, described this external surface of cardan wheel is provided with wear-resistant coating, the center of described cardan wheel body is also provided with centre hole, on the cardan wheel body of described centre hole periphery, offer seven trapezoid-shaped openings that hoop is arranged, spacing between adjacent two trapezoid-shaped openings is 3 ~ 5mm, and four jiaos of described trapezoid-shaped openings are provided with the chamfering that radius is 2 ~ 5mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model cardan wheel has advantages of lightweight, high strength, high service life.
Accompanying drawing explanation
Fig. 1 is the utility model Universal wheel structure schematic diagram.
Wherein:
Centre hole 1
Trapezoid-shaped openings 2.
The specific embodiment
Referring to Fig. 1, a kind of cardan wheel that the utility model relates to, it comprises cardan wheel body, the material of described cardan wheel body is aluminium or aluminum alloy, described this external surface of cardan wheel is provided with wear-resistant coating, the center of described cardan wheel body is also provided with centre hole 1, on the cardan wheel body of described centre hole 1 periphery, offer seven trapezoid-shaped openings 2 that hoop is arranged, the external diameter of described cardan wheel body is 72mm, the diameter of described centre hole 1 is 39mm, the trapezoidal height of described trapezoid-shaped openings 2 is 24mm, spacing between adjacent two trapezoid-shaped openings 2 is 3 ~ 5mm, four jiaos of described trapezoid-shaped openings 2 are provided with the chamfering that radius is 2 ~ 5mm, the severe of described cardan wheel body is 4.5 ~ 5kg/m.
