Abstract
The utility model relates to a bearing, in particular to an embedded type self lubricating joint bearing, which comprises an outer sleeve (1) and an inner sleeve (2). Inner surface of the outer sleeve (1) is of concave spherical shape, and a plurality of solid lubricating blocks (4) is embedded in the outer sleeve. Moreover, the inner surface of the outer sleeve is provided with a lubricant coating. A sealing element (3.3) is fixed on check ring (5). Sealing rim (7) of the sealing element (3.3) is a concave spherical surface which meshes with convex spherical surface of the outer surface of the inner sleeve (2). For the roller way of the outer sleeve is provided with a lubricating coating, the utility model cancels slip conjunction and displays function of lubrication. The sealing element is arranged on the check without influencing bearing area. Therefore, the utility model with simple and compact structure can conduct sealing performance and influence no self aligning.
Description
Affiliated technical field
The utility model belongs to a kind of bearing, mainly proposes a kind of mosaic self-lubricating joint shaft bearing.
Background technique
At present, the mosaic self-lubricating joint shaft bearing is mainly used in a hinge portion of water conservancy project industry gate, long-term underwater operation.Its general overcoat adopts the subdivision structure, is concave spherical surface in the overcoat roll sleeve, and several solid sticks are inlayed in overcoat inside, realizes oil-free lubrication, and lining the outer surface of is spherical.Because it does not spray lubricating layer at the overcoat internal surface, must carry out running-in before using, to form lubricant film, to the unconditional running-in of the bearing of large-size.Simultaneously, its sealing configuration has following two kinds basically, and as shown in Figure 1, O RunddichtringO 3-1 is adopted in its sealing, though simple, reliable, reduced loaded area owing to having occupied the raceway space; Seal ring 3-2 shown in the accompanying drawing 2 is positioned at the outside of bearing, though do not influence loaded area, influences the aligning performance of bearing, and structure is complicated, not compact.
Summary of the invention
The purpose of this utility model promptly is the mosaic self-lubricating joint shaft bearing that proposes a kind of simple in structure, reliable performance.
The purpose of this utility model can adopt following technological scheme to realize: it comprises overcoat, interior cover, be inlaid with solid stick in the overcoat, on the overcoat internal surface of inlaid solid lubrication piece, has a lubricant coating, Sealing is installed on the back-up ring, the sealing lip of Sealing is a concave spherical surface, the protruding sphere tight connecting of itself and lining the outer surface of.
From the above mentioned, the utility model since on overcoat internal surface raceway spraying one deck solid lubricant, can make it before use need not running-in, play the effect of supplemental lubrication.Because Sealing of the present utility model is positioned on the back-up ring, does not influence loaded area, not only seals, and does not influence its aligning performance again, and simple in structure, compact.
Description of drawings
Accompanying drawing 1 is the existing joint shaft bearing structural representation that adopts the O RunddichtringO.
Accompanying drawing 3 is the utility model structural representation.
Accompanying drawing 4 is the structural representation of the utility model Sealing.
Among the figure, 1, overcoat, 2, interior cover, 3-1, O RunddichtringO, 3-2, seal ring, 3-3, Sealing 4, solid stick, 5, back-up ring, 6, screw, 7, sealing lip.
Embodiment
In conjunction with the accompanying drawings, further specify mode of execution of the present utility model:
As shown in Figure 3, described joint shaft bearing mainly comprises overcoat 1, interior cover 2, interior cover 2 outer surfaces are spherical in shape, the internal surface of overcoat 2 is concave spherical surface, and a plurality of solid sticks 4 are inlayed in its inside, has a solid lubricant coating at the internal surface of overcoat 1, the Sealing 3-3 of bearing is fixed on the back-up ring 5, back-up ring 5 is fixed on the overcoat 1 by screw 6, and the sealing lip 7 of Sealing 3-3 bottom is a concave spherical surface, the protruding sphere tight connecting of itself and interior cover 2 outer surfaces.
Claims (1)
1, a kind of mosaic self-lubricating joint shaft bearing, have overcoat (1), interior cover (2), overcoat (1) internal surface is concave spherical surface, a plurality of solid sticks (4) are inlayed in inside, it is characterized in that: the internal surface of overcoat (1) has a lubricant coating, Sealing (3-3) is fixed on the back-up ring (5), and the sealing lip (7) of Sealing (3) is a concave spherical surface, the protruding sphere tight connecting of itself and interior cover (2) outer surface.
