Abstract
The utility model relates to a universal rolling ball, which is composed of a main casing and the rolling ball. The rolling ball is formed by assembling two hollow half balls provided with a reinforcing rib, the central connecting screw thread and a peripheric clamping groove. The top of the main casing forms a concave shape, and an arc-shaped steel ball supporting frame is arranged in the main casing. The steel balls are arranged compactly above the supporting frame, and the outer periphery of the main casing is provided with the screw thread used for connecting and fixing the external objects. The upper edge of the main casing is surrounded with the rolling balls and is covered with a limit ring. The utility model has the advantages of small frictional resistance, high traveling speed, flexible turning, strong bearing power, solidity and durability. The utility model is suitable for various objects, such as the bottom supporting universal rolling balls of tables, chairs and the mechanism devices, and is also suitable for being assembled into a rolling ball supporting platform to support large scale equipment to move on the supporting platform.
Description
The utility model belongs to and is installed in some objects bottom, and the supporting object is made the univesal sphere device of flexible universal movement; Be particularly related to a kind of being installed on the plane of trajectory orbital, supporting space amusement ball is made the Roll device of universal rolling.
At present, existing univesal sphere device, its main casing is a cylindrical shape, and spin circularizes supporting by one group of steel ball, is half rolling, half sliding friction between spin and the main casing, and flexibility is relatively poor.Chinese patent " ZL96216115.2 univesal sphere device " is provided with upper and lower two groups of steel ball ring-shaped bearings between main casing and spin, improved the rolling friction between main casing and the spin, but structure is comparatively complicated.
The purpose of this utility model is, designs and produces a kind of Roll, is provided with arc steel ball supporting frame, and the steel ball that gathers is above made supporting surface, to enlarge the load-bearing rolling surface; Spin makes hollow assembly type, to alleviate the spin deadweight, improves the frictional force of spin and supporting surface, thereby adapts to the bigger rolling requirement that is written into space amusement ball of rolling bearing diameter more.
Roll of the present utility model is made up of main casing and spin, and spin is two hollow hemisphere and assembles, and is provided with stiffening rib, middle part connecting thread and peripheral draw-in groove in the hollow hemisphere; The main casing end face is concave shape, built-in arc steel ball supporting frame, and the steel ball that gathers above the bearing support, the main casing outer periphery is provided with the screw thread that is connected and fixed usefulness with external object, and position limit cycle around spin, has been added a cover in the main casing upper edge.
Using method of the present utility model is: Roll is connected than big article with other with screw thread, promptly can be used as the Roll seat of supporting usefulness, any object face that is placed on it all can roll flexibly; Also Roll can be used screw thread and is connected than small item, then can roll flexibly than small item.
The utility model has the advantages that: surface friction drag is little, and gait of march is fast, and break-in is flexible, and bearing capacity is strong, and is sturdy and durable.Be applicable to various items, as the bottom supporting Roll of table, chair, machinery; Also be applicable to be assembled into the spin cushion cap, on cushion cap, move with the supporting main equipment.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of Roll of the present utility model
Fig. 2 is the organigram of spin
Fig. 3 is the organigram of arc steel ball supporting frame
As seen from Figure 1, Roll of the present utility model, be made up of main casing and spin, spin 1 is placed on main casing central authorities, and main casing 2 end faces are concave shape, built-in arc steel ball supporting frame 3, densely covered steel ball 4 above the bearing support, the main casing outer periphery is provided with the screw thread that is connected and fixed usefulness with external object, the main casing upper edge, around spin, added a cover position limit cycle 5.
As seen from Figure 2, spin 1 is two hollow hemisphere 6,7 and assembles, and is provided with stiffening rib, middle part connecting thread and peripheral draw-in groove in the hollow hemisphere.
As seen from Figure 3, arc steel ball supporting frame 3 peripheries are provided with screw thread, can be connected and fixed with main casing, and the steel ball 4 that gathers above the bearing support forms the steel ball supporting face.
Claims (2)
1, a kind of Roll is made up of main casing and spin, it is characterized in that, spin is two hollow hemisphere and assembles, and is provided with stiffening rib, middle part connecting thread and peripheral draw-in groove in the hollow hemisphere; The main casing end face is concave shape, built-in arc steel ball supporting frame, and steel ball gathers above the bearing support; Position limit cycle around spin, has been added a cover in the main casing upper edge.
