Abstract
The utility model relates to a rotating member connecting structure of a connecting rod. The rotating member connecting structure of the connecting rod comprises a cast iron connecting member and hinge supporting bases. The cast iron connecting member is provided with a tightly-ejecting screw. The hinge supporting bases are arranged at two ends of the cast iron connecting member. The hinge supporting bases are connected together through the tightly-ejecting screw. A steel inner ring is arranged on the tightly-ejecting screw between the hinge supporting bases. A rubber ring is arranged on the outer surface of the steel inner ring. A steel outer ring is arranged on the outer surface of the rubber ring, and the cast iron connecting member is arranged on the outer surface of the steel outer ring. The rotating member connecting structure of the connecting rod is simple in structure and low in cost. The rotating member connecting structure of the connecting rod can achieve the purpose of ensuring smaller bearing force and higher moving frequency.
Description
Technical field
The utility model relates to bar linkage motion mechanism, relates in particular to a kind of revolving meber linkage structure of connecting rod.
Background technique
At present, although the linkage mechanism application is very extensive, mostly all adopt rolling bearing or sliding bearing, this structure is only suitable in the less equipment of motion frequency, will cause the irregular damage of bearing if the motion frequency of equipment strengthens.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of revolving meber linkage structure that can guarantee less bearing capacity and the higher connecting rod of motion frequency.
For addressing the above problem, the revolving meber linkage structure of a kind of connecting rod described in the utility model is characterized in that: it comprises and is provided with cast iron link and the rocker bar bearing that presses closer screw rod; The two ends of described cast iron link are respectively equipped with described rocker bar bearing, link together by the described screw rod that presses closer between this rocker bar bearing; The described screw rod that presses closer between described rocker bar bearing is provided with the steel inner ring, and the outer surface of this steel inner ring is provided with rubber ring; The outer surface of described rubber ring is provided with the steel outer ring, and the outer surface of this steel outer ring is provided with described cast iron link.
The utility model compared with prior art has the following advantages:
1, owing to being provided with built-in rubber ring in the utility model, therefore, the impact force buffering of cast iron link can be protected cast iron link and the effect that presses closer screw rod thereby play in use, reach the purpose of the less bearing capacity of assurance and higher motion frequency; Simultaneously, rubber ring can guarantee that steel inner ring and steel outer ring are not worn and adhesion because of rotation.
2, the utility model is simple in structure, with low cost.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1-press closer screw rod 2-rocker bar bearing 3-steel inner ring 4-rubber ring, 5-steel outer ring 6-cast iron link.
Embodiment
As shown in Figure 1, a kind of revolving meber linkage structure of connecting rod, it comprises and is provided with cast iron link 6 and the rocker bar bearing 2 that presses closer screw rod 1.The two ends of cast iron link 6 are respectively equipped with rocker bar bearing 2, link together by pressing closer screw rod 1 between this rocker bar bearing 2; The screw rod 1 that presses closer between rocker bar bearing 2 is provided with steel inner ring 3, and the outer surface of this steel inner ring 3 is provided with rubber ring 4; The outer surface of rubber ring 4 is provided with steel outer ring 5, and the outer surface of this steel outer ring 5 is provided with cast iron link 6.
Cast iron link 6 is by being driven by external force to make this structure to do plane motion under ordering about small angle is rotating.
