Abstract
The utility model discloses a super-heavy-duty universal wheel carrier which comprises a top plate, a rotary disk, a first supporting plate and a second supporting plate. The first supporting plate and the second supporting plate are respectively fixedly connected with the rotary disk. The super-heavy-duty universal wheel carrier is characterized in that a regular polygonal hole is formed in the center of the top plate over the rotary disk. One end of a central bolt is located in the regular polygonal hole, and the cross section of the end of the central bolt is matched with the regular polygonal hole in shape. The other end of the central bolt penetrates through the rotary disk and is connected with a nut in a threaded mode. A tapered roller bearing is arranged between the rotary disk and the central bolt. A thrust ball bearing is arranged between the top plate and the rotary disk. The super-heavy-duty universal wheel carrier improves load capacity of trundles and is simple in structure, fewer in manufacturing procedures and flexible in steering.
Description
Technical field
The utility model relates to a kind of industrial castor, is specifically related to a kind of super-heavy load Universal castor.
Background technology
Castor is divided into direction-caster and universal caster wheel, the structure of universal caster wheel allows 360 degree rotations, because it moves lightly, turns to flexible characteristics extensively to be applied in the fields such as medicine equipment, industrial apparatus, supermarket trolleys, furniture, the universal caster wheel supporting construction complexity of prior art, Fabrication procedure is many, and in order not influence the alerting ability that it turns to, bearing load and shock resistance are limited; Especially in super-heavy load castor field, the load of castor and the service life of castor and stability in use, safety, impact resistance are seldom taken into account especially.
Summary of the invention
In order to solve the problem that prior art exists, the utility model provides that a kind of bearing load is big, impact resistance is strong, does not also influence castor simultaneously and turns to super-heavy load Universal castor flexibly.
The utility model is achieved through the following technical solutions: it comprises top board, rotating disk, first stay bearing plate and second stay bearing plate, described first stay bearing plate, second stay bearing plate are captiveed joint with rotating disk respectively, it is characterized in that: the top board center of described rotating disk top is provided with the equilateral polygon hole, center bolt one end is positioned at the equilateral polygon hole, and this end cross-sectional plane of center bolt and equilateral polygon hole shape coupling, the center bolt other end passes rotating disk and is connected with nut thread, also is provided with tapered roller bearing between rotating disk and the center bolt; Be provided with thrust ball bearing between described top board and the rotating disk.
Be provided with dust ring between the top board of described castor bracing frame and the rotating disk, be provided with cover of dust between nut and the tapered roller bearing.
Also be provided with the oil nozzle of carrying lubricating oil on the rotating disk of described castor bracing frame.
The beneficial effects of the utility model are: simple in structure with respect to traditional bracing frame, owing to increased thrust ball bearing, tapered roller bearing makes that the castor bracing frame turns to flexibly, bearing load is big.The center bolt top is the equilateral polygon structure, with respect to traditional cylindrical structural, has reduced relatively moving between top board and the center bolt, makes top board more steady.
Description of drawings
Fig. 1 is left view of the present utility model.
Fig. 2 is front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is explained in detail.
A kind of super-heavy load Universal castor comprises top board 4 as shown in Figure 1, rotating disk 3, the first stay bearing plates 1 and second stay bearing plate 2, described first stay bearing plate 1, second stay bearing plate 2 respectively with rotating disk 3 weld togethers, between described top board 4 and rotating disk 2, be provided with thrust ball bearing 10.
As shown in Figure 2, top board 4 centers of described rotating disk 3 tops are provided with the equilateral polygon hole, center bolt 5 one ends are positioned at the equilateral polygon hole, and center bolt 5 these end cross-sectional planes and equilateral polygon hole shape coupling, center bolt 5 other ends pass rotating disk 3 and are threaded with nut 11, also are provided with tapered roller bearing 6 between rotating disk 3 and the center bolt 5; Be provided with thrust ball bearing 10 between described top board 4 and the rotating disk 3.
Described center bolt 5 and nut 11 be through gluings processing, and ageing treatment after assembling is used for reinforcing being threaded of center bolt 5 and nut 11.
Be provided with dust ring 7 between the top board 4 of described castor bracing frame and the rotating disk 3, be provided with cover of dust 9 between nut 11 and the tapered roller bearing 6, avoid dust rubbish to enter bearing, influence its service life.
Also be provided with the oil nozzle 8 of carrying lubricating oil on the rotating disk 3 of described super-heavy load Universal castor, relatively the periodical maintenance of castor.
The principle that the utility model improves load is: described tapered roller bearing 6 can be decomposed into suffered power along the power of taper roller side with perpendicular to the power of taper roller side, in tapered roller bearing 6 inside, power perpendicular to the taper roller side can be cancelled out each other, and therefore supporting the power of bearing is a component of 4 holding capacity of top board.
Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from essence and the scope of technical solutions of the utility model.
