Abstract
The utility model discloses an upright universal caster. The aim of the upright universal caster is to provide a caster which has the advantages of simple structure, convenient manufacture, big bearing capacity, and uneasy breakup. The upright universal caster comprises a wheel ball, a wheel carrier covered on the outside of the wheel ball, and bearing balls. A round concave pit is arranged on the top surface of the wheel carrier arranged between the wheel carrier and the wheel ball, the circumference of the pit is overspread with the bearing balls, and the wheel ball is connected with the bearing ball. The inner surface circumference of the wheel carrier undercut is adequately distributed at least three deep-pits, every deep-pit is provided with a positioning ball, the position of the wheel ball is fixed, and the wheel ball is rotated flexibly by the positioning bowl. The inner surface of the wheel carrier forms a cylindrical shape, and the orifice of the wheel carrier inner surface is connected with a positioning ring through the screw thread. The minimum inner diameter of the positioning ring is smaller than the diameter of the wheel ball, the abscission of the wheel ball is prevented. The top of the wheel carrier is provided with a fixed plate, the circumference of the fixed plate are providedwith fixed holes, the fixed holes are used for the installation of the upright universal caster. The upright universal caster is applied to the moving balls of a chair, a travel bag, a car frame, etc.
Description
Technical field
The utility model relates to a kind of cardan wheel.
Background technology
Existing cardan wheel is various informative, but groundwork is similar, all is to be formed by combining by cardan wheel, wheel shaft, the eccentric frame of cardan wheel and main shaft.Its weak point: the object that cardan wheel is housed when mobile, break-in at once, cardan wheel must first be done eccentric motion around main shaft, can be after reaching straight direction by change direction motion, it is not only required great effort, and movement locus of object is inaccurate, makes the object wigwag motion.In addition, because cardan wheel acting point and main shaft be not on same straight line, make eccentric frame except bearing axial force, also bear an additional eccentric moment, the cardan wheel pressure-bearing is big more, eccentric distance is big more, the additional eccentric moment that cardan wheel bears is also big more, and eccentric frame of the cardan wheel that makes and main shaft etc. are fail in bending easily.
Summary of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, and a kind of vertical type cardan wheel that moves steadily, do not have additional eccentric moment is provided.
In order to address the above problem, the technical scheme of vertical type cardan wheel: comprise the wheel ball, cover on outer wheel carrier, the load-bearing spin of wheel ball, wheel top of support between wheel carrier and wheel ball is shaped on circular pit, is covered with the load-bearing spin on the circumference of pit, and the wheel ball contacts with the load-bearing spin.Be evenly distributed with at least three heavy holes on the inside face circumference of wheel carrier end opening, be placed with the location spin in each heavy hole, with the tight pulley ball position and the wheel ball is rotated flexibly.The wheel carrier inside face is cylindrical its aperture with the nest that has been threaded, and the minimum diameter of nest is less than the wheel ball diameter, to prevent that taking turns ball comes off.Wheel carrier is shaped on adapter plate on the top, around the adapter plate fixed orifice is arranged, and is used for the installation of vertical type cardan wheel.
That the vertical type cardan wheel of making according to such scheme has is simple in structure, easily manufactured, load-carrying capacity is big, non-damageable advantage.
Description of drawings
Fig. 1 is the structural representation of vertical type cardan wheel;
Fig. 2 is the Pareto diagram of load-bearing spin in wheel top of support circular pit;
Fig. 3 is the A-A cutaway view of Fig. 1.
Wherein: 1, wheel ball; 2, wheel carrier; 3, pit; 4, load-bearing spin; 5, location spin; 6, nest; 7, adapter plate; 8 fixed orifices.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the structural representation of vertical type cardan wheel.The vertical type cardan wheel has the wheel ball 1 that contacts to earth, cover on the outer wheel carrier 2 of wheel ball 1, wheel carrier 2 end faces between wheel carrier 2 and wheel ball 1 are shaped on round pit 3, the full load-bearing spin 4 of the circumferential upper part of pit 3, as shown in Figure 2, load-bearing spin 4 is a steel ball, and wheel ball 1 contacts with load-bearing spin 4.Be evenly distributed with six heavy holes on the inside face circumference of wheel carrier 2 end openings, be placed with a location spin 5 in each heavy hole, with the position of tight pulley ball 1 and wheel ball 1 is rotated flexibly as shown in Figure 3, location spin 5 is a steel ball.Wheel carrier 2 inside faces are cylindrical its aperture with the nest 6 that has been threaded, and the minimum diameter of nest 6 prevents to take turns ball 1 and comes off less than the diameter of wheel ball 1.Wheel carrier is shaped on adapter plate 7 on 2 tops, around the adapter plate 7 fixed orifice 8 is arranged, and is used for the fixing of vertical type cardan wheel.
Claims (7)
1, a kind of vertical type cardan wheel comprises the wheel ball, covers on outer wheel carrier, the load-bearing spin of wheel ball, it is characterized in that the wheel top of support between wheel carrier and wheel ball is shaped on circular pit, is covered with the load-bearing spin on the circumference of pit, and the wheel ball contacts with the load-bearing spin.
2, vertical type cardan wheel according to claim 1 is characterized in that described wheel carrier inside face is cylindrical.
3, vertical type cardan wheel according to claim 1 is characterized in that being evenly distributed with on the inside face circumference of described wheel carrier end opening at least three heavy holes, is placed with the location spin in each heavy hole.
4, vertical type cardan wheel according to claim 1 is characterized in that described wheel carrier aperture with the nest that has been threaded, and the minimum diameter of nest prevents to take turns ball and comes off less than the wheel ball diameter.
