Abstract
The utility model discloses a universal caster with a completely arc-shaped wheel face, and belongs to the technical field of common casters. The universal caster comprises an upper cover plate, a plane bearing, a support and a wheel, the upper cover plate is rotatably connected with the support through the plane bearing, and the support is connected with the wheel through a bolt and a nut. The wheel is provided with the arc-shaped wheel face comprising a center arc-shaped wheel face A and arc-shaped wheel faces B on two sides, and the radius of the center arc-shaped wheel face A is larger than that of each of the arc-shaped wheel faces B on the two sides. As the universal caster is in rolling friction with the ground and the friction force is related to resisting moment, when gas in a tire is insufficient in the use process of the universal caster, only low resisting moment is generated, and increase of the friction force is unobvious. Compared with the prior art, the universal caster has the advantages that a cart, a case, a chair and the like with the universal caster are easy to use and can carry more articles, labor intensity is relieved, and working efficiency is improved.
Description
Technical field
The utility model is a kind of universal caster wheel, and particularly the universal caster wheel of the complete arc wheel face of a kind of tool belongs to general castor technical field.
Background technology
Universal caster wheel is a kind of object bottom of being installed in, and makes it to be convenient to mobile parts, is widely used in the products such as go-cart, casing, seat, for people at home, the fields such as travelling, medical treatment are indispensable.Existing universal caster wheel generally has two kinds, and a kind of is universal caster wheel with upper cover plate, during installation, is to be fixed on the object with the upper cover plate of 2-4 bolt with universal caster wheel; Another kind during installation, is in the screw rod insertion go-cart base plate mounting hole with main shaft with the universal caster wheel of main shaft, uses nut screwing clamping.But the sort of universal caster wheel no matter, the wheel face that adopts all is the plane, shown in Fig. 1-1, Fig. 1-2, because universal caster wheel and ground produce friction of rolling, when the gas in the use procedure, in the tire is not enough, produce easily larger resisting moment, coefficient of rolling friction is increased, the friction force that produces increases, the usage comparison effort.
The utility model content
The purpose of this utility model is in the above-mentioned prior art, when the gas in the universal caster wheel use procedure, in the tire is not enough, produce easily larger resisting moment, coefficient of rolling friction is increased, the friction force that produces increases, the defective of usage comparison effort, the universal caster wheel of the complete arc wheel face of a kind of tool is provided, when the gas of can reach in the universal caster wheel use procedure, tire is interior is not enough, only produce less resisting moment, it is little that coefficient of rolling friction is changed, and friction force increases not obvious, and usage comparison is purpose easily.
The technical scheme taked of the utility model is to achieve these goals: the universal caster wheel of the complete arc wheel face of a kind of tool, comprise upper cover plate, surface bearing, support and wheel, and described upper cover plate is rotationally connected by surface bearing and support; Described support is connected by bolt, nut with wheel; The wheel face of described wheel is the arc wheel face, and described arc wheel face comprises the arc wheel face B of central part arc wheel face A and both sides, and the radius of described central part arc wheel face A is greater than the radius of the arc wheel face B of both sides.
The radius of described central part arc wheel face A is 25.4mm.
The radius of the arc wheel face B of described both sides is 10.0mm.
Action principle: because universal caster wheel and ground produce friction of rolling, the size of its friction force is relevant with the size of resisting moment.The universal caster wheel of the complete arc wheel face of tool, in use, when the gas in the tire is not enough, only produce less resisting moment, it is little that coefficient of rolling friction is changed, and friction force increases not obvious, and usage comparison is light.Analyzing in addition, although friction force and area have nothing to do, is relevant with the concrete interlock situation on wheel face and earth's surface.In the actual use procedure of universal caster wheel, the road conditions more complicated of contact, AT STATION, the places such as harbour, market, hospital, it is very smooth that ground seems, and in fact because the people of process is many, the earth's surface can produce many rough defectives, the universal caster wheel wheel face is wider, larger with contact area of ground, run into more serious earth's surface defective with regard to easier, thereby friction coefficient is increased, it is large that friction force also just becomes.So universal caster wheel and the earth's surface area of contact of the complete arc wheel face of tool are little, in actual use, the friction force that produces is also just less.
Compared with prior art, the beneficial effects of the utility model are: the products such as the go-cart of employing the utility model structure, casing, seat are in use lighter, can load more thing, reduce labor intensity, and increase work efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to restriction of the present utility model.
To shown in Figure 3, the universal caster wheel of the complete arc wheel face of a kind of tool comprises upper cover plate 1, surface bearing 2, support 3 and wheel 4 such as Fig. 2-1, and described upper cover plate 1 is rotationally connected by surface bearing 2 and support 3; Described support 3 is connected by bolt, nut with wheel 4; The wheel face of described wheel 4 is the arc wheel face, and described arc wheel face comprises the arc wheel face B42 of central part arc wheel face A41 and both sides.
The radius of described central part arc wheel face A41 is 25.4mm, and the radius of the arc wheel face B42 of described both sides is 10.0mm.
Above described be the situation of universal caster wheel product of the complete arc wheel face of tool of upper cover plate 1, certainly, in universal caster wheel product main shaft, the complete arc wheel face of tool, its assembling and action principle are identical, repeat no more.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
