Abstract
The utility model discloses a centrifugally rotating caster which comprises a wheel axle assembly and a wheel installed on the wheel axle assembly. The centrifugally rotating caster is characterized in that the diameter of the portion, contacted with the wheel, of the wheel axle assembly is smaller than the diameter of the portion, contacted with the wheel axle assembly, of the wheel. The wheel rotates centrifugally around the wheel axle assembly. According to the centrifugally rotating caster, the wheel rotates centrifugally around the wheel axle assembly, when the wheel encounters an uneven ground, vibration can be reduced, and meanwhile noise can be reduced due to the structure.

The specific embodiment
Referring to Fig. 1 to Fig. 5, the embodiment of the castor of a kind of centrifugal rotation that provides at the utility model, comprise axle assembly 1 and the wheel 2 that is arranged on described axle assembly 1, described axle assembly 1 contact with described axle assembly 1 less than described wheel 2 partly the diameter D2 of the diameter D1 of part that contacts with described wheel 2, described wheel 2 is around the centrifugal rotation of described axle assembly 1.The utility model is arranged to the decentraction structure with center of rotation and the axle assembly 1 of wheel 2, makes the centrifugal running of wheel 2.When running into the situation of ground injustice, this free-running fit structure can reduce vibrations, thereby eliminates the part noise.
Referring to Fig. 3 to Fig. 9, in above-described embodiment that the utility model provides, described axle assembly 1 comprises a wheel shaft 11 and the two bearings 12,13 that is arranged on described wheel shaft 11, form grasping part 14 between two described bearings 12,13, the part-structure of described wheel 2 is arranged in described grasping part 14.Described bearing 12,13 is used for the part-structure of the described wheel 2 of clamping, makes it when centrifugal rotation, can not be offset.Described grasping part 14 refers to the cavity between two bearings 12,13, and two bearings 12,13 are as two sidewalls, and bearing 12,13 central structure are as diapire.When wheel 2 rotated, bearing 12,13 outer wall contacted with the inwall of described wheel 2, or the part that wheel 2 stretches in described grasping part 14 contacts with the diapire of described grasping part 14.These two kinds of supporting way all can, need and can adjust according to design.
Referring to Fig. 3, Fig. 4 and Figure 10 to Figure 13, in above-described embodiment that the utility model provides, described wheel 2 comprises a hard inner core 21 and the soft outer ring 22 that is wrapped on described inner core 21, the part of described inner core 21 is positioned at described grasping part 14, and the external diameter of described grasping part 14 is less than the internal diameter of described inner core 21.The external diameter of the described grasping part 14 here refers to the external diameter of its diapire, be described axle assembly 1 contact with described wheel 2 part diameter D1.The internal diameter of described inner core 21 be described wheel 2 contact with described axle assembly 1 part diameter D2.Described inner core 21 plays the effect of support, and makes wheel 2 to fit together with axle assembly 1.
