The aim of the utility model can be achieved by the following technical scheme:
the novel wear-resistant copper sleeve comprises a cylindrical body, and is characterized by also comprising a pin shaft, a cylindrical first cylinder body, a cylindrical second cylinder body and a cylindrical third cylinder body, wherein the first cylinder body is positioned in the body, the second cylinder body is positioned between the first cylinder body and the body, the third cylinder body is tightly pressed between the second cylinder body and the body, the first cylinder body and the second cylinder body are made of metal materials, the third cylinder body is made of flexible materials,
the first cylinder body is provided with a first penetrating connecting hole, the second cylinder body is provided with a second penetrating connecting hole, the inner side of the body is provided with a concave positioning notch,
the pin shaft is sequentially penetrated at the first connecting hole of the first cylinder body and the second connecting hole of the second cylinder body, the inner end of the pin shaft pushes the third cylinder body into the positioning notch, the outer end part of the pin shaft extends out of the inner side of the first cylinder body,
the first connecting hole, the second connecting hole, the positioning notch and the pin shaft form a plurality of connecting units, and the connecting units are circumferentially and uniformly distributed on the inner side of the body.
Because the round pin axle is connected simultaneously on barrel one, barrel two and body in the novel wear-resisting copper sheathing, consequently, can make barrel one, barrel two and body stable connection under the effect of round pin axle.
The flexible cylinder III is positioned between the cylinder I and the cylinder II, and meanwhile, the inner end of the pin shaft pushes the local position of the cylinder III to the positioning notch.
The third cylinder has two functions:
firstly, eliminating a gap between the first cylinder and the second cylinder;
the second pin shaft has elastic acting force on the pin shaft, and the outer end of the pin shaft is ensured to stably extend out of the first cylinder body.
Of course, the main function of the first cylinder body is to position the pin shaft, so that the pin shaft is prevented from deflecting in the stress process.
It can be seen that when the shaft or other mechanical elements are connected in the novel wear-resistant copper sleeve, the pin shafts are in contact with the outer sides of the shaft or other mechanical elements, and due to the adoption of the wear-resistant materials, the arrangement of the plurality of pin shafts avoids the direct contact between the inner sides of the copper sleeve and the shaft or other mechanical elements, so that the wear resistance of the novel wear-resistant copper sleeve is effectively improved.
Typically, the pins are graphite material.
In the novel wear-resistant copper sleeve, the third cylinder is made of rubber materials.
The structure can enable the position of the cylinder body III which is locally pressed by the inner end of the pin shaft to be smoothly embedded into the positioning notch of the body after the local position of the cylinder body III is pressed by the inner end of the pin shaft.
In the novel wear-resistant copper sleeve, the third cylinder is tightly pressed between the first cylinder and the second cylinder.
Thus, the stability of the joint of the first cylinder and the second cylinder can be improved.
In the novel wear-resistant copper sleeve, the thickness dimensions of the body, the first cylinder and the second cylinder are the same.
In the novel wear-resistant copper sleeve, the wall thickness of the cylinder body III is 1/3-1/2 of the wall thickness of the body.
The structure can improve the overall structure and promise, and simultaneously, the pin shaft can obtain proper elastic thrust.
In the novel wear-resistant copper sleeve, the connecting part is arranged on the third cylinder body along the circumferential direction of the third cylinder body, the outer side of the connecting part protrudes out of the third cylinder body, the inner side of the connecting part is recessed into the third inner side of the third cylinder body, the outer side of the connecting part is matched with the positioning notch, and the inner side of the connecting part is matched with the inner end of the pin shaft.
The arrangement of the connecting part can enable the cylinder body III to effectively avoid the pin shaft, and enable the outer side of the cylinder body III to be stably embedded into the positioning notch, and the pin shaft can be stably embedded into the connecting part.
Because the third cylinder is positioned between the first cylinder and the second cylinder, more connecting parts can be coated at the inner end of the pin shaft, and rigid contact between the pin shaft and the second cylinder is avoided.
In the novel wear-resistant copper sleeve, the connecting part and the cylinder body are of an integrated structure.
In the novel wear-resistant copper sleeve, the connecting part and the three side parts of the cylinder body are provided with transition parts in smooth transition.
The transition part can enable the connecting part to be smoothly embedded into the positioning notch.
In the novel wear-resistant copper sleeve, the diameter size of the pin shaft is larger than the length size of the pin shaft.
In the novel wear-resistant copper sleeve, the diameter of the pin shaft is 3-5 times of the wall thickness of the body.
Such a construction reduces the wall thickness dimension of the entire copper sleeve.
Compared with the prior art, the novel wear-resistant copper bush is characterized in that the pin shaft is stably positioned on the inner side of the body under the action of the first cylinder body and the second cylinder body, meanwhile, the inner end of the pin shaft is stably subjected to elastic pushing action under the action of the third cylinder body, the outer end of the pin shaft is ensured to be stably contacted with the shaft or other parts in the copper bush, and the pin shaft is made of graphite material, so that the wear resistance of the whole copper bush is effectively improved.
Meanwhile, the first cylinder, the second cylinder and the third cylinder are stably connected to the inner side of the body, so that the whole copper sleeve is compact in structure and has high practical value.
