Abstract
The utility model relates to a joint bearing which comprises an outer ring with an inner sphere and an inner ring with an outer sphere. The inner wing is arranged in the outer ring. The joint bearing is characterized in that: an assembling groove is arranged on the inner wall of the outer ring, the inner ring is suitable for being arranged in the outer ring by the assembling groove, a ring-shaped outer oil groove is arranged on the contact face between the outer ring and the inner ring, and an oil nozzle which is communicated with the outer oil groove is arranged on the side wall of the outer ring; wherein the inner ring is suitable for being arranged in the outer ring by the assembling groove, so as to be convenient for the assembling and disassembling of the inner ring and the outer ring; in the actual using, the inner ring can be replaced according to the wear condition, and the entire bearing does not need to be replaced; as the replacing of the inner ring is convenient, the labor cost is saved. Moreover, the oil nozzle which is communicated with the outer oil groove is arranged on the side wall of the outer ring, so that oil needs to be added only by the oil nozzle on the side wall of the outer ring when auxiliary lubricating oil is added, thereby realizing the auxiliary lubrication at the side face and being convenient for oil adding. Oil seals are arranged at the two sides of the inner sphere of the outer ring, and can exert the function of dust prevention.
Description
Technical field
The utility model relates to a kind of joint shaft bearing, is specifically related to a kind of compound plain radial bearing.
Background technique
Chinese patent literature ZL01274554.5 discloses a kind of plain radial bearing, form by outer ring and inner ring, the inner ring outer spherical surface has an annular lubrication groove and intersects lubrication groove, this intersection lubrication groove has oilhole at the intersection lubrication groove with the intersection point place that encircles inner ring outer spherical surface lubrication groove for being crossed as mutually greater than 0 ° of lubrication groove.
Above-mentioned the deficiencies in the prior art part is: inner ring is more easy to wear in actual the use, when the inner ring wearing and tearing are serious, just needs to change bearing, and when changing bearing, need the dismounting jump ring, the program complexity, and a whole set of bearing must be scrapped after dismounting repeatedly, and user cost is higher.In addition, the tank filler sleeve of existing joint shaft bearing has brought inconvenience for oiling work on the cambered surface of outer ring.
The model utility content
Technical problem to be solved in the utility model provides the joint shaft bearing that a kind of inner ring is changed and oiling is all more convenient.
For solving the problems of the technologies described above, joint shaft bearing of the present utility model comprises: have the outer ring and the inner ring of being located in the outer ring with outer spherical surface of inner ball surface, be characterized in: the inwall of outer ring is provided with fitting recess, and inner ring is suitable for being located in the outer ring by this fitting recess; Have the outer oil sump of annular on the surface of contact of outer ring and inner ring, the sidewall of outer ring is provided with the oil nozzle that communicates with described outer oil sump.
Further, the both sides of the inner ball surface of described outer ring are provided with oil sealing.
Further, described fitting recess has a pair of, and is symmetrically set on the inwall of outer ring; With respect to adopt the scheme that a fitting recess is only arranged on the inwall of outer ring, adopt the scheme of a pair of fitting recess, its fitting recess can be more shallow, be convenient to process and do not influence the integrity and the reliability of outer ring.
Further, stud with self lubricating material on the outer spherical surface of described inner ring.
Further, the inner circle wall central authorities of described inner ring are provided with the inner oil sump of annular, and inner oil sump communicates with described outer oil sump.
The utlity model has positive effect: in (1) joint shaft bearing of the present utility model, the inwall of outer ring is provided with fitting recess, and inner ring is suitable for being located in the outer ring by this fitting recess, thereby has made things convenient for the Assembly And Disassembly of inner ring and outer ring, be convenient to change inner ring, saved labour cost.In addition, the sidewall of outer ring is provided with the oil nozzle that communicates with described outer oil sump, so when adding auxiliary lube oil, only need to refuel by the oil nozzle on the sidewall of outer ring, has realized the side lubrication assistant, has made things convenient for oiling.(2) in the joint shaft bearing of the present utility model, the inner ball surface both sides of outer ring are provided with oil sealing, play the dust-tight effect.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of joint shaft bearing of the present utility model;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
