Abstract
The utility model discloses a self-lubrication high temperature resistance shafting bearing including a shaft block with an axle hole, a bearing outer ring arranged in the axle hole of the shaft block, and a bearing inner ring the outer surface of which is in a sliding cooperation with the inner surface of the bearing outer ring. The bearing out ring and inner ring are formed from high temperature resistance material with a self-lubrication function. The bearing does not need injecting lubricating oil or other lubricating materials. The bearing has a simple structure and a low cost which is very suitable to work in a high temperature zone and the service life of the bearing is 3-7 times as long as a traditional bearing.
Description
Technical field:
The utility model relates to a kind of high temperature resistant bearing of selflubricating that is used for supporting movement spare.
Background technique:
Traditional bearing generally includes bearing outer ring and is arranged on the interior bearing inner race of bearing outer ring, in order to alleviate friction, with steel ball or roller it is separated between two surfaces of bearing outer ring and bearing inner race relative movement.Because bearing is a kind ofly to be used to support radially or the member of the movement parts such as rotating shaft of axial load, even and if the bearing of said structure adopts the less relatively rolling friction mode of friction factor also can produce bigger frictional force in rotation process, its method that reduces surface friction drag can only adopt less lubricant oil of friction factor or graphite.But, lubricant oil or graphite can consume gradually along with the continuity of its working time in bearing, a kind of mode at make-up oil in bearing is to adopt independent pump group supply shaft bearing capacity oil, and another kind of mode is by the special supply shaft bearing lubrication oil of the fuel tank of splendid attire lubricant oil; And adopt graphite is to be inlaid with the graphite post on bearing inner race, when consuming, the graphite post also needs constantly it to be replenished, so, no matter the bearing of said structure adopts oil lubrication, still adopt graphite lubrication all to need to consume lubriation material, and need be, and then cause its user cost to improve to its operating process that replenishes.Another problem is, in some occasion, bearing need be worked under the environment of very severe, as the roller bed bearing working in the environment of 800 ℃ of left and right sides high temperature, and the bearing of this occasion operation need carry out water cooling, simultaneously it is carried out all unusual difficulties of oiling or additional graphite, make the bearing of its working life far below the following use of normal temperature.
For this reason, the name of No. 2791340, Chinese patent bulletin is called " self-lubricating oil-containing sliding bearing " and provides a solution.The inner ring of the bearing that this patent proposed is to contain the sintered powder of pore and cooperate with the outer ring sphere, and inner ring is installed in the outer ring by fixing frame.Its meaning is that the lubricant oil that utilizes pore to provide can reduce the frictional force between the surface of contact of inner ring and outer ring, and then makes bearing realize selflubricating.With regard to bearing, must smoothly contact between the surface of contact of its inner ring and outer ring, otherwise can seriously influence working life of bearing.And the inner ring of this bearing will make inner peripheral surface smoothly bring many difficulties to processing because of adopting the structure of pore.
In addition, the name of No. 2606821, Chinese patent bulletin is called " the box-like sliding bearing of linner ball type three-layered node " and provides another kind of solution.The middle cover that this patent adopts an overcoat and is slidingly matched with this overcoat sphere, and the interior cover that cooperates with the middle cover rolling, and adopt the cylndrical surface between middle cover and the interior cover, its meaning is to want to utilize the little cylndrical surface of area of contact to reduce surface friction drag, and utilizes the bigger sphere of surface of contact to increase surface friction drag between overcoat and the middle cover.But this kind bearing needs problems such as oiling and processing difficulties too.
Summary of the invention:
The purpose of this utility model provides the never easily high temperature resistant bearing of selflubricating of problem such as supplemental lubrication material and processing difficulties in bearing of a kind of characterisitic solution of utilizing material itself.
The high temperature resistant bearing of selflubricating that the utility model proposes comprises the bearing support in a tape spool hole and is arranged on the interior bearing outer ring of axis hole of this bearing support, and the bearing inner race that is slidingly matched of the internal surface of outer surface and described bearing outer ring, and bearing outer ring and bearing inner race are made by material high temperature resistant and that have a self-lubricating function.
The internal surface of described bearing outer ring is the inside concave arc surface of level and smooth depression radially, and the outer surface of bearing inner race be the radially outward projection and with the corresponding convex globoidal of radian of the concave arc surface of bearing outer ring.But the annulus that described bearing outer ring is a length to be less than or equal to axis hole length and to be made by high temperature resistant and self lubricating material, the internal surface of this annulus is the segment shape face that caves inward.
The annulus that described bearing inner race is made by high temperature resistant and self lubricating material, the internal surface of this annulus is cylindrical, its outer surface is the corresponding arc-shaped surface of segment shape face with bearing outer ring.
Described bearing support comprises main body and is arranged on the connecting plate of lower body part that the axis hole periphery on the main body is provided for holding the circular groove chamber of bearing outer ring.
The selflubricating that the utility model proposed is high temperature resistant, and bearing adopts little material bearing outer ring and the bearing inner race of friction factor, as adopt high temperature resistant selflubricating high-sulfur alloy steel, so, the bearing of this kind structure does not need to annotate lubricant oil or other lubriation material, cause its structure very simple, fabricating cost is very low, and can omit lubriation material; Simultaneously, the bearing of this kind structure is very suitable in high-temperature zone work, as is applied in occasion such as roller bed, its working life be traditional bearing 3-7 doubly.
Description of drawings:
Accompanying drawing 1 is the embodiment's of the high temperature resistant bearing of selflubricating that proposes of the utility model a surface structure schematic representation.
Embodiment:
Referring to Fig. 1, this figure provides the embodiment's of the high temperature resistant bearing of selflubricating that the utility model proposes overall appearance structure.This bearing is by bearing support 1 and bearing outer ring 2 basically, and bearing inner race 3 these three parts constitute.Wherein, bearing support 1 comprises main body 12 that has axis hole 11 and the connecting plate 13 that is arranged on main body 12 bottoms, and axis hole 11 peripheries on main body 12 are provided for holding the circular groove chamber 14 of bearing outer ring 2; Bearing outer ring 2 is to be made of an annulus, its outer surface 21 is connected with the fixedly connected or tight contact-type of the internal surface of axis hole 11, its internal surface 22 is provided with the concave arc surface or the segment shape face of radially inside and level and smooth depression, and the length of bearing outer ring 2 is less than or equal to axis hole 11 length; And bearing inner race 3 also is made of an annulus, its outer surface 31 be radially outward projection and with the corresponding convex globoidal of radian or the arc-shaped surface of the concave arc surface of bearing outer ring 2, its internal surface 32 is cylindrical.But bearing outer ring 2 can be made by high temperature resistant and self lubricating material with bearing inner race 3, as adopts material such as high temperature resistant selflubricating high-sulfur alloy steel, adopts between the two to be slidingly matched.
