Abstract
The invention provides a rod end spherical plain bearing structure. Through the use of the structure, external dimensions of the whole rod end spherical plain bearing and wall thickness of an outer ring are ensured at the same time, the bearing capacity of the rod end spherical plain bearing is improved, the separation of an inner ring and the outer ring is conveniently realized, the convenient replacement of the inner ring or the outer ring is realized, and the production cost is effectively reduced. The structure comprises the outer ring with a pull rod, and the inner ring is arranged in the outer ring; and the structure is characterized in that breaches are respectively formed in the inner sides of the both ends of the outer ring, the length of the breaches and the outer diameter of the inner ring are corresponding, the width of the breaches and the thickness of the inner ring are corresponding, the inner ring is put into the outer ring through the breaches, and anastomotic spherical contact is formed between the outer ring and the inner ring.
Description
Technical field
The present invention relates to the technical field of bearing mnanufacture, be specially a kind of spherical plain bearing rod end structure.
Background technique
Joint shaft bearing is spherical bearing, basic model is by having in spherical slip sphere contact surface, outer ring forms, inner ring and outer ring time processing shaping, spherical plain bearing rod end is that the outer ring of joint shaft bearing is provided with stayed pole, existingly see Fig. 1, spherical plain bearing rod end structure is made up of with the inner ring 2 by outer spherical surface an outer ring 1 with inner ball surface and stayed pole and one, because spherical plain bearing rod end structure is with pull bar, inner ring and outer ring cannot time processing shaping, existing spherical plain bearing rod end structure normally adopts the joint shaft bearing of basic model to embed one with in the overcoat 3 of pull bar, or on outer ring, flange is set, flange is being closed up after inner ring is put into outer ring, realize inner ring and put into outer ring, because spherical plain bearing rod end needs to bear larger load, the joint shaft bearing of basic model is adopted to embed one with in the overcoat of pull bar, while the boundary dimension ensureing whole spherical plain bearing rod end, the wall thickness of thinning outer ring certainly will be wanted, this reduces the radial bearing capacity of spherical plain bearing rod end, adopt on outer ring and flange is set, close up flange again after inner ring is put into outer ring, realize inner ring and put into outer ring, radial force is less, and inner ring shaping with outer ring after cannot be separated, inner ring or outer ring cannot be changed after damaging, get only entirety scrap, add cost of production.
Summary of the invention
For the problems referred to above, the invention provides a kind of spherical plain bearing rod end structure, while the boundary dimension ensureing whole spherical plain bearing rod end, ensure that the wall thickness of outer ring, add the radial bearing capacity of spherical plain bearing rod end, improve the axial strength of spherical plain bearing rod end simultaneously, and realize being separated of inner ring and outer ring easily, realize being convenient for changing of inner ring or outer ring, effectively reduce cost of production.
Its technological scheme is such: a kind of spherical plain bearing rod end structure, it comprises the outer ring of band pull bar, inner ring is provided with in described outer ring, it is characterized in that: described outer ring is respectively arranged with gap inside two ends, the length of described gap is corresponding with the external diameter of described inner ring, the width of described gap is corresponding with the thickness of described inner ring, and described inner ring puts into described outer ring by described gap, and described outer ring and described inner ring form identical sphere-contact.
It is further characterized in that: arrange groove inside described inner ring, is provided with self lubricating material in described groove; Described self lubricating material comprises nylon, fiberglass reinforcement, teflon, MoS
2, graphite is mixed and processed.
In said structure of the present invention, outer ring is respectively arranged with gap inside two ends, the length of gap is corresponding with the external diameter of inner ring, the width of gap is corresponding with the thickness of inner ring, inner ring laterally puts into gap, rotated by inner ring and put into outer ring, outer ring and inner ring form identical sphere-contact, outer ring is put into because inner ring rotates, realize being separated of inner ring and outer ring easily, realize being convenient for changing of inner ring or outer ring, effectively reduce cost of production, while the boundary dimension ensureing whole spherical plain bearing rod end, ensure that the wall thickness of outer ring, add the radial bearing capacity of spherical plain bearing rod end, and do not need flange due to outer ring, outer ring can adopt high-strength material, inner ring can not axially be escaped, add the axial bearing capacity of spherical plain bearing rod end.

Fig. 1 is existing spherical plain bearing rod end structural representation;
Fig. 2 is spherical plain bearing rod end structural representation of the present invention;
Fig. 3 is the sectional view of bowing of Fig. 2.
Embodiment
See Fig. 2, a kind of spherical plain bearing rod end structure, it comprises the outer ring 1 of band pull bar, and be provided with inner ring 2 in outer ring 1, outer ring 1 is provided with gap 3 inside two ends, the length of gap 3 is corresponding with the external diameter of inner ring 2, the width of gap 3 is corresponding with the thickness of inner ring 2, and inner ring 2 puts into outer ring 1 by gap 3, inside outer ring 1 spherically, spherically, outer ring 1 and inner ring 2 form the sphere-contact coincide in the outside of inner ring 2, outer ring 1 is provided with gap 3 inside two ends, rotate after the laterally inserted gap 3 of inner ring 2, realize the outside mating spherical surfaces of sphere and inner ring 2 inside outer ring 1, define complete spherical plain bearing rod end, while the boundary dimension ensureing whole spherical plain bearing rod end, ensure that the wall thickness of outer ring, add the radial bearing capacity of spherical plain bearing rod end, and realize being separated of inner ring and outer ring easily, realize being convenient for changing of inner ring or outer ring, effectively reduce cost of production, and do not need flange due to outer ring, outer ring can adopt high-strength material, inner ring can not axially be escaped, add the axial bearing capacity of spherical plain bearing rod end.
Arrange groove 5 inside inner ring 2, be provided with self lubricating material 4 in groove 5, self lubricating material 6 injects in groove 5 by the mode of injection moulding from gap 3, and molding and forming self lubricating material in groove 5, achieves the selflubricating of bearing inner race simply, easily.
Self lubricating material comprises nylon, fiberglass reinforcement, teflon, MoS
2, graphite etc. is mixed and processed.
