Abstract

The utility model provides a plane limitless wheel, comprising a frame wheel, a frame wheel shaft and a sag shaft wheel which is arranged on the frame wheel. The frame wheel is arranged on the frame wheel shaft, and a shaft hole of the sag shaft wheel is matched with a short shaft on the frame wheel in a rotary mode. The shaft line of the sag shaft wheel is perpendicular to the frame wheel shaft, and the outer circular arc of the sag shaft wheel which is arranged on the frame wheel and the projection on the projection surface which is perpendicular to the frame wheel shaft are mutually connected to form a round. The center of the circle and the projection coincide, and the projection of the shaft line of the frame wheel shaft is perpendicular to the projection surface of the frame wheel shaft. With novel structure, the utility model has flexibility and smoothness in moving on a plane. So the utility model can support an object to freely move and can also help students to understand the synthesis and the decomposition of the movement.

Description

Infinitely take turns on the plane

The utility model belongs to cardan wheel, relates in particular to the wheel that the supporting object moves freely in the plane.

At present cardan wheel mostly is the monocycly universal caster wheel, and this wheel is used to support object and moves in the plane, as seat, hand barrow, sofa etc. because cardan wheel commonly used is the single-wheel structure, when moving as the plane underaction freely, stationarity is poor.

The purpose of this utility model provides a kind of plane of novel structure and infinitely takes turns, and it moves in the plane is freely, has alerting ability and stationarity when mobile.This wheel had both supported object and had moved freely in the plane, also can be used as a kind of instruments used for education, helped the student to understand the synthetic of motion and decompose.

For achieving the above object, take following technical scheme: the unlimited wheel in plane comprises the frame wheel, frame wheel shaft and the vertical arbor wheel that is contained on the frame wheel, the frame wheel is assembled by framework and stub member, there is axis hole at the middle part of framework, the axis hole outer wall has the supporting that connects with stub member, have two vertical arbor wheels at least on the unlimited wheel, there is axis hole at the center that the wheel that hangs down is taken turns, this takes turns the minor axis normal-running fit on hole and the frame wheel, and the axle that is contained in the vertical arbor wheel on the frame wheel is perpendicular to the frame wheel shaft, for a complete unlimited wheel, the external arc of vertical arbor wheel is being interconnected to a circle perpendicular to the projection on the projecting plane of frame wheel shaft, its center of circle is overlapping perpendicular to the projection on the projecting plane of frame wheel shaft with the axis of frame wheel shaft.

The hang down cydariform that is shaped as of arbor wheel, broad in the middle, small in ends, the external arc of its axial cross section such as is at a radius arc.

The wheel because the utility model frames up on the frame wheel shaft, the frame wheel is gone up the vertical arbor wheel of dress, the axle of vertical arbor wheel is perpendicular to the frame wheel shaft, radius arc such as each vertical arbor wheel external arc is, the external arc that is contained in the vertical arbor wheel on the frame wheel is being interconnected to a circle perpendicular to the projection on the projecting plane of frame wheel shaft, its center of circle is overlapping perpendicular to the projection on the projecting plane of frame wheel shaft with the axis of frame wheel shaft, this apparatus structure novelty, its motion in the plane is freely, and therefore unlimited wheel has alerting ability and stationarity when mobile in the plane.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the axonometric drawing of the utility model embodiment:

Fig. 2 is the front view of Fig. 1;

Fig. 3 is the axonometric drawing of the utility model embodiment frame wheel construction.

Embodiment: the unlimited wheel in plane is made up of frame wheel 7, frame wheel shaft 4 and the vertical arbor wheel 3 that is contained on the frame wheel 7, frame wheel 7 is assembled by framework 8 and stub member 1, there is frame axle hole 5 at the middle part of framework 8, axis hole 5 outer walls have the supporting 9 that connects with stub member 1, there is keyway at wheel 7 the position that frames up on the frame wheel shaft 4, guarantee on axle 4, to be equipped with two or more frames and took turns 7 o'clock, do not have between the frame wheel and relatively rotate.Frame wheel 7 on the frame wheel shaft 4 has two vertical arbor wheels 3 at least, the cydariform that is shaped as of arbor wheel 3 hangs down, broad in the middle, small in ends, radius arc such as the external arc 2 of its axial cross section is, both ends of the surface are circular flat, there is axis hole 6 at the center of vertical arbor wheel 3, minor axis 10 normal-running fiies on axis hole 6 and the frame wheel 7, the axis normal that is contained in the vertical arbor wheel 3 on the frame wheel 7 is in frame wheel shaft 4, the external arc 2 of vertical arbor wheel 3 is being interconnected to a circle perpendicular to the projection on the projecting plane of frame wheel shaft 4, its center of circle is overlapping perpendicular to the projection on the projecting plane of frame wheel shaft 4 with the axis of frame wheel shaft 4.
