Abstract
The utility model discloses a universal ball castor, solving the disadvantages of large stress and the inefficacious rotation of a load bearing ball existing in a single-ring ball arrangement rack via changing the single-ring ball arrangement rack of a dynamic and static-adjustable universal castor into a multi-ring ball arrangement rack on the basis of the dynamic and static-adjustable universal castor. The aims of large stress for multi-ring ball arrangement and the flexible rotation of the load bearing ball are obtained.
Description
The utility model belongs to cardan wheel and makes the field.
Prior art in the utility model prior art field is: the application number that this contriver declares is No. 88201978.3 " dynamic-static adjustable universal wheel ", has realized any rotation, the purpose that sound is adjustable though this is taken turns.But, be individual pen cloth pearl type because this pearl shelf structure of taking turns adopts, thereby to cause the relative motion of ball and bearing ball be that unidirectional single pearl is stressed, consequently stressed when excessive when bearing ball, the ball rotation is ineffective.
Design goal of the present utility model is: at weak point of the prior art, be the omnipotent cardan wheel of the stressed or multiway multi-bead stress structure of unidirectional many pearls when designing a kind of ball and bearing ball relative motion.
Design plan of the present utility model is: omnipotent cardan wheel is made up of attaching screw, connecting panel, sheathing, ball rack, housing, ball, bearing ball and retainer.Its ball rack is the half garden shape that is made of odd number pearl band, and pearl is with and is embedded with several balls, and the angle between pearl band and the pearl band is 120 degree or 60 degree.The pearl of ball rack with on the ball hole of bead be open-work or two kinds of structures of blind hole, its objective is: generally speaking, the pearl of ball rack with on ball hole be through hole structure, be used for the omnipotent cardan wheel of steel structure or steel-plastic structure, the blind hole structure is used for the omnipotent cardan wheel of nonmetal structure.Owing to adopt the ball rack of said structure, thereby the stressed drawback of unidirectional single pearl when having solved ball and bearing ball relative motion preferably, thereby realized the purpose of the stressed or multiway multi-bead stress of unidirectional many pearls, make cardan wheel under stressed excessive situation, can rotate flexibly and comfortably.
The utility model compared with prior art, changing individual pen cloth pearl type pearl frame is multi-turn cloth pearl type pearl frame, thereby solved weak point of the prior art preferably, realize the purpose of the stressed or multiway multi-bead stress of unidirectional many pearls, made cardan wheel under stressed excessive situation, can rotate flexibly and comfortably.
Description of drawings:
Fig. 1 and Fig. 2 are the scheme drawings of first kind of embodiment of omnipotent cardan wheel.
Fig. 3 and Fig. 4 are the scheme drawings of second kind of embodiment of omnipotent cardan wheel.
Embodiment:
First kind of enforcement of omnipotent cardan wheel: at first according to the mould of making connecting panel 2 illustrated in figures 1 and 2, sheathing 3, ball rack 4, housing 5, bearing ball 7, treat to carry out punching press or injection moulding after it makes, just can obtain required parts.Ball 6, attaching screw 1 outsourcing.Retainer 8 is by the prior art processing and fabricating.After treating that above-mentioned work is ready, attaching screw 1 is fixed on the bottom of housing 5; Ball 6 is contained in the pearl of ball rack 4 and is with, and the ball rack that will have ball then places in the housing 5, and the bearing ball 7 of packing into closes up; Retainer 8 is spun on the sidepiece of housing 5, and sheathing 4 is enclosed within on the attaching screw 1, screws on nut, screws on connecting panel 2 at last and get final product.
Claims (3)
1, a kind of by attaching screw 1, connecting panel 2, sheathing 3, ball rack 4, the omnipotent cardan wheel that housing 5, ball 6, bearing ball 7 and retainer 8 are formed, it is characterized in that: described ball rack 4 is the half garden shapes that are made of odd number pearl band, and is embedded with several balls 6 on pearl is with.
2, omnipotent cardan wheel according to claim 1 is characterized in that: the angle between pearl band and the pearl band is 120 degree or 60 degree.
3, omnipotent cardan wheel according to claim 1 is characterized in that: the pearl of ball rack 4 with on the ball hole of bead be open-work or blind hole.
