Abstract
The invention discloses a high-bearing-capacity trundle. The high-bearing-capacity trundle comprises a fixing plate, a fixed seat and a rotating seat. The fixed seat is arranged on the lower surface of the fixing plate. A first bearing is arranged between the rotating seat and the fixed seat and used for connection. A cylinder perpendicularly extending to the upper portion of the fixed seat is arranged in the middle of the rotating seat. An inner stepped hole is formed in the middle of the fixed seat, and the cylinder can penetrate the inner stepped hole. A second bearing which is arranged on the outer portion of the cylinder in a sleeving manner is arranged in the inner stepped hole. Two symmetrical vertical supporting plates are arranged on the lower portion of the rotating seat. A rolling wheel is arranged between the vertical supporting plates. In this way, the high-bearing-capacity trundle achieves steering especially by means of cooperation of the first bearing and the second bearing, so that the rotating flexibility and the torsion strength are improved, and the bearing capacity can be improved. The manufactured high-bearing-capacity trundle is higher in durability and not prone to breakage in use.
Description
Technical field
The present invention relates to castor field, particularly relate to a kind of high-mechanic castor.
Background technology
In order to conveniently moving, part furniture, household electrical appliances or seat bottom have been installed castor and have been promoted.Castor is mainly divided into directional wheel and cardan wheel, and directional wheel load-carrying capacity is strong, but can not at will turn, and the turning rate of cardan wheel is more flexible.
Because cardan wheel can realize turning to, Application comparison is extensive.Roll structure is enclosed in the many employings one of common cardan wheel, and friction is large, and load-carrying capacity is limited, and the anti-twisting property of rotational structure is poor, easily in use ruptures.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of high-mechanic castor, improves load-carrying capacity and torsional strength.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high-mechanic castor, comprise: adapter plate, permanent seat and rotation seat, described permanent seat is arranged on the lower surface of adapter plate, described rotation seat is arranged on the below of permanent seat with one heart, described rotation seat be provided with clutch shaft bearing between permanent seat and be connected, the cylinder extended perpendicularly to above permanent seat is provided with in the middle part of described rotation seat, the ladder endoporus passed through for cylinder is provided with in the middle part of described permanent seat, the second bearing being set in cylindrical outer is provided with in described ladder endoporus, two symmetrical support risers are provided with below described rotation seat, a roller is provided with between described support riser, described roller comprises irony wheel hub and is coated on the polyurethane wear resistant layer on irony wheel hub cylindrical.
In a preferred embodiment of the present invention, described rotation seat with permanent seat is respectively arranged with the groove corresponding with clutch shaft bearing.
In a preferred embodiment of the present invention, described clutch shaft bearing is thrust ball bearing, and described second bearing is tapered roller bearing.
In a preferred embodiment of the present invention, described cylinder and rotation seat are punching press integral structure.
In a preferred embodiment of the present invention, described cylinder cylindrical top is provided with screw thread, described cylinder is provided with a clamp nut.
The invention has the beneficial effects as follows: a kind of high-mechanic castor that the present invention points out, the cooperation that have employed clutch shaft bearing and the second bearing especially realizes turning to, both the alerting ability of rotation and antitorque intensity had been improve, load-carrying capacity can be improved again, the castor durability made is better, not easily in use ruptures.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of high-mechanic castor one of the present invention preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
