Description
Technical field
The present invention relates to a kind of bearing more particularly to a kind of bearing spiders of high abrasion.
Background technology
Bearing spider, bearing spider are required in the engineering machinery involved by the industries such as metallurgy, mine, electric power, cement
The component for being used for spring bearing on bearing body is mounted in, bearing spider is generally divided into：Split bearing support, sliding bearing
Bearing, rolling bearing bearing, flanged (FLGD) bearing spider, bearing with spherical outside surface bearing etc..And it is in the engineering of harsh environments
Machinery is higher and higher to the requirement of bearing spider wearability, is easily worn during existing bearing spider use, especially axis
Bearing is held in high-speed and high-temperature environment, as the rise of temperature is with continuing, the bearing spider rate of wear is drastically accelerated, meeting when serious
Bearing spider is caused to be scrapped, influences the normal operation of equipment and the stability of equipment, security, so cooling directly influences axis
Hold the wearability of bearing.
And the steel for manufacturing bearing spider in the prior art are most of without enough obdurability and wear-resisting property.At present,
Melting is difficult again for steel with abrasion-resistant bearing bearing, and needs high temperature water-tenacity treatment, and production cost is higher.
Existing bearing spider inner wall easily causes inter deterioration when rubbing with the regular close connection of bearing, can because
These wear and directly contribute bearing and bearing spider unstable working condition, so as to influence the service life of bearing spider, therefore have
Necessity improves the wearability of bearing spider inner wall.
The content of the invention
To solve the above problems, the present invention provides, a kind of wearability is good, and thermal diffusivity is good, the low abrasion-resistant cast axis of production cost
Hold bearing.
To achieve the above object, the technical solution adopted in the present invention is：A kind of bearing spider of high abrasion, including bearing
Bearing pedestal and the bearing spider retainer ring with bearing spider pedestal integrally connected, bearing spider are fixed collar and are formed into axis hole,
Be provided with graphene layer on the shaft hole inner wall, bearing spider retainer ring is internally provided with circulation pipe, circulation pipe one end be provided with into
Water hole, the other end are provided with apopore, and inlet opening is arranged on the one side lower end of bearing spider retainer ring, and apopore is arranged on into water
The positive upper end of homonymy in hole.
The further graphene layer is arranged on detachable snap ring inner wall, and detachable snap ring is rabbeted by convex block in axis
On the inner wall of hole.
The thickness of the further graphene layer is 17-20 μm.
The further bearing spider pedestal is each side respectively arranged with a circular mounting hole.
The further bearing spider is made of alloy material, and the chemical composition and weight percent of alloy material are：
C：3.0-3.9%, Si：0.4-0.7%, Ni：1.5-1.9%, Mn：0.7-1.0%, Cu：0.5-1.4%, S：0.05-
0.08%, P：0.05-0.08%, Cr：20-22%, surplus Fe.
A kind of bearing spider of high abrasion of the present invention is not easy to be ground during use, and especially bearing spider is at a high speed
In use, circulation pipe annular design can guarantee integrally cools down to bearing spider under hot environment, cooling efficiency is improved, ensure that axis
The wearability of bearing is held, because having cooling system, thermal diffusivity is good, so low wear rate, scraps so as to not easily lead to bearing spider,
It the problem of influencing the normal operation of equipment and stability, security, solves the effect in machine work due to friction and causes
The problem of bearing spider is easily damaged with bearing due to temperature is excessively high improves the wearability of bearing spider, even high temperature is high
Under fast environment, the wear intensity of bearing spider is also smaller；It is simple in structure, it is easy to install, it is not required to increase new facility and material,
It is at low cost, using graphene layer is set on bearing spider inner wall, the wearability of bearing spider is effectively improved, is effectively prolonged
The service life of bearing spider is grown, graphene layer is too thin to be not achieved wear-resisting requirement, too thick increase cost, graphene layer of the present invention
Thickness take into account wear-resisting and cost and make both to be optimal；Pass through the test of many times and excellent to trace element for alloy material
After change, the alloy material matched according to aforementioned proportion effectively reduces production cost, together and ensure that its wearability, extends
Its service life.Graphene layer, which is arranged on detachable snap ring inner wall, can ensure in graphene layer by fast in time when destroying
Graphene layer is replaced in victory, ensure that operation stability, the security of equipment.

Fig. 2 is the main structure diagram of the retainer ring after the detachable snap ring of installation of the embodiment of the present invention.
Specific embodiment
The present invention is described in further details below by embodiment, embodiment is only used for illustrating the present invention, and unlimited
The scope of the present invention processed.
A kind of bearing spider of high abrasion as shown in Figure 1, 2, including bearing block base 2 and with bearing block base 2 integrally
The bearing block retainer ring 1 of connection, the left and right sides of the bearing block base 2 are respectively arranged with a circular mounting hole 6, bearing block
Retainer ring 1 surrounds axis hole 3, is provided with graphene layer 5 on 3 inner wall of axis hole, the graphene layer 5 or is arranged on detachable card
