Detailed Description
Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 to 3 are schematic structural views of a novel flange joint bearing according to a first embodiment of the present utility model. The novel flange joint bearing comprises a bearing seat 10, a spherical joint 20 arranged in the bearing seat 10 and a bushing 30 inserted in the spherical joint 20. It is conceivable that the new flange joint bearing further comprises other functional modules, such as locking rings, lubricants, etc., which are known to the person skilled in the art and will not be described in detail here.
The bearing seat 10 may be made of a common nonmetallic material, and includes a bearing seat body 11 and an assembly through hole 12 provided on the bearing seat body 11 for assembling the spherical joint 20, wherein the assembly through hole 12 has a spherical structure. The shape and structure of the bearing housing body 11 may be designed according to practical needs, and in the first embodiment, the bearing housing body 11 is a rectangular plate structure. The assembly through hole 12 is formed in the center of the rectangular plate-like structure. It is contemplated that the axial length of the assembly throughbore 12 may be greater than the thickness of the rectangular plate-like structure in order to accommodate the axial length of the spherical joint 20. In the first embodiment, the bearing housing 10 further includes at least two fixing through holes 13 provided at equal intervals on the housing body 11, and the fixing through holes 13 are used for mounting screws.
The spherical joint 20 may be made of a common nonmetallic material, and is accommodated in the assembly through hole 12, and the radial outer side of the spherical joint 20 is also in a spherical structure, and the outer diameter of the spherical structure of the spherical joint 20 is equal to the inner diameter of the spherical structure of the assembly through hole 12. The spherical joint 20 has a central hole 21, and a chamfer 22 is formed on a side of the central hole 21 away from the bearing seat 10. The chamfer 22 may facilitate the entry of the bushing 30 into the spherical joint 20. The spherical joint 20 and the bearing housing 10 may be manufactured by a two-shot injection molding process. The secondary injection molding process is the prior art, and is not repeated here. In the present utility model, the spherical joint 20 may be injection molded, and then the bearing seat 10 may be injection molded outside the spherical joint 20, thereby completing the manufacture and assembly of the bearing seat 10 and the spherical joint 20.
The second to sixth embodiments are different only in the structure and shape of the bearing housing 11 to adapt to different applications. In the second embodiment, the bearing housing body 11 is a circular ring concentric with the assembly through hole 10. In the third and fourth embodiments, the bearing housing body 11 is a rod-shaped structure, which may be circular or polygonal in cross section. The assembly through hole 12 is provided at one end of the bearing housing body 11. It is contemplated that the outer diameter of the assembly throughbore 12 may be greater than or less than the maximum diameter of the rod-like structure, depending on the actual needs. In the fifth embodiment, the bearing housing 11 is an arch bridge structure. The assembly through hole 12 is provided in the center of the arch bridge structure. It is of course also conceivable that the dimensions of the assembly through-hole 12 and the arch bridge structure may be designed according to practical requirements. In the sixth embodiment, the bearing housing 11 has a parallelogram structure, which is similar to that of the first embodiment, and will not be described herein.
The bushing 30 is inserted into the spherical joint 20 from a side of the spherical joint 20 having the chamfer 22. The bushing 30 is hollow and cylindrical, and the outer diameter of the bushing 30 is equal to the inner diameter of the central hole 21 of the spherical joint 20 and is in interference fit, so that the bushing 30 is inserted into the spherical joint 20 in a press-fit manner, thereby assembling the bushing 30 and the spherical joint 20 together, and further preventing the bushing 30 from being separated from the spherical joint 20 when the bushing 30 is not subjected to external force. The bush 30 can prevent the abrasion between the spherical joint 20 and the shaft, thereby ensuring the accuracy and dimensional stability of the bearing inner bore, and the bush 30 is replaceable, thereby reducing the cost of the whole flange joint bearing. Specifically, when the bearing housing 10 is used for a period of time, due to the existence of abrasion, only the bushing 30 can be directly replaced when the precision is reduced, and the spherical joint 20 and the bearing housing 10 are not required to be replaced, so that waste is avoided, and the cost is reduced. Meanwhile, since only the bushing 30 can be made of a wear-resistant material, and the spherical joint 20 does not need to be made of a wear-resistant material, but can be made of a general material, a relatively expensive wear-resistant material can be saved, and the cost can be further reduced.
The bushing 30 prevents the wear between the spherical joint 20 and the shaft, thereby ensuring accuracy and dimensional stability of the bore. In this embodiment, the bushing 30 is an aluminum bushing using a PTFE composite. The PTFE composite itself is prior art and will not be described in detail herein, it has good wear resistance. Because of the good high and low temperature resistance and steam corrosion resistance of the PTFE composite material, the novel flange joint bearing can operate in a low temperature range of 180 ℃ and a low temperature range of minus 40 ℃ and in a humid environment without reducing the precision and the dimensional stability of an inner hole.
Compared with the prior art, in the novel flange joint bearing provided by the utility model, the bushing 30 is inserted into the spherical joint 20 and is in interference fit with the spherical joint 20, and the bushing can avoid abrasion between the spherical joint 20 and a shaft, so that the precision and the dimensional stability of an inner hole of the bearing are ensured, and meanwhile, the bushing 30 has replaceability, so that the cost of the whole flange joint bearing can be reduced. Specifically, when the bearing housing 10 is used for a period of time, only the bushing 30 can be directly replaced when the precision is reduced due to the existence of abrasion, and the spherical joint 20 and the bearing housing 10 are not required to be replaced, so that the waste is avoided, and the cost is reduced. Meanwhile, since only the bushing 30 can be made of a wear-resistant material, and the spherical joint 20 does not need to be made of a wear-resistant material, but can be made of a general material, a relatively expensive wear-resistant material can be saved, and further, the cost can be reduced. .
The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
