Description
Technical field
The utility model relates to steel rolling equipment ancillary technique field, relates in particular to a kind of oven charging and discharging machine trailing arm roller.
Background technique
Charging and discharging machine is positioned at outside oven at present, oven is sent steel plate into, held out to main being responsible for, the interior temperature of stove is in 850 degree left and right under normal circumstances, temperature is higher, steel plate adopts driving handling to realize to the transfer of charging and discharging machine conventionally, put into the deadweight of steel plate on trailing arm generally all in 5000KG left and right, add the impact force of steel plate, very huge to the injury of trailing arm roller; Traditional bearing copper sleeve formula trailing arm roller is in the time being subject to high temperature and powerful impact force action, the as easy as rolling off a log damage that causes bearing and copper sheathing, seriously reduce the working life of trailing arm roller, cause charging and discharging machine trailing arm to change frequent, delaying normal steel plate heat-treated stream turns, and there is the problem that it is difficult that hot environment is bought oil in traditional trailing arm roller bearing, the operational maintenance frequency is high and difficulty is large.
CN2888166Y discloses a kind of axle sleeve of solid lubricant inlaid, its axle sleeve is made up of steel, on the circumferential surface of axle sleeve, be shaped with equally distributed and with axle sleeve inside and outside wall connect hole, in hole, be inlaid with solid lubricant, this structure one is that bearing capacity is large, the 2nd, in the time of work, can make to produce one deck isolating film between axle and cover, play effect more anti-bonding than alone lubricant oil and that friction factor is little.But in actual using process, just bring into play above-mentioned effect at the initialization phase of operation, and the solid lubricant that it is inlayed only exposes one deck and the axle friction generation lubricated granules of axle sleeve internal surface, after its surface is very fast and axle sleeve inner circle polishes, can cause the phenomenon of steel axle sleeve and axle journal dry grinding, produce thus worse phenomenon, axle journal and axle sleeve gummed and wearing and tearing are more serious, damage faster.
Model utility content
The utility model provides a kind of oven charging and discharging machine trailing arm roller, can effectively and reliably improve bearing lubrication situation, thereby overcomes gummed and premature wear between axle journal and axle sleeve, the working life of extending shaft and axle sleeve and service cycle.
Realizing the technological scheme that above-mentioned purpose takes is: a kind of oven charging and discharging machine trailing arm roller, comprise trailing arm roll shaft, axle sleeve and bearing support, and described axle sleeve circumference is laid with radial blind holes or through hole, and graphite column and Compress Spring are set in described blind hole or through hole.
Described axle sleeve is Cuprum alloy product.
Described graphite column and described blind hole or through hole transition fit.
Described bearing support arranges cooling mechanism.
Described cooling mechanism comprises the cooling liquid flow channel, input duct, the fluid pipeline that are arranged in described bearing support, and described input duct and fluid pipeline are communicated with described cooling liquid flow channel respectively, and described input duct arranges recycle liquid pump and liquid storage tank.
Described axle sleeve and described bearing support interference fit.
Described cooling liquid flow channel is the some circular grooves that are arranged on described bearing support inwall and are parallel to each other, and between adjacent two circular grooves, liquid chunnel hole is set.
Oven charging and discharging machine trailing arm roller of the present utility model, is laid with radial blind holes or through hole at axle sleeve circumference, and graphite column and Compress Spring are set in described blind hole or through hole, forms self oiling bearing.And, under the effect of Compress Spring, can remain the pressure contact of graphite column and trailing arm roll shaft, axle sleeve and trailing arm roll shaft are all the time in selflubricating state, and be only used in the graphite column more having renewed again after graphite column has all worn away, can save a large amount of graphite materials, also greatly extend the replacement cycle, the corresponding steel rolling manufacturing efficiency that improved.Described axle sleeve adopts Cuprum alloy product, can effectively reduce the wearing and tearing of trailing arm roll shaft, avoids the scuffing of axle sleeve and trailing arm roll shaft surface of contact, extends working life and the service cycle of trailing arm roll shaft.Secondly; by the setting of cooling mechanism; trailing arm roll shaft, axle sleeve and bearing support operational temperature conditions are effectively improved; greatly reduce thus the hot strength requirement to axle sleeve and even trailing arm roll shaft; working life and the service cycle of trailing arm roll shaft and axle sleeve have been extended simultaneously; manufacture and the operating cost of having saved oven charging and discharging machine, reduced dead time, improved manufacturing efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, oven charging and discharging machine trailing arm roller of the present utility model, comprises some groups of trailing arm roll shafts 1, axle sleeve 3 and bearing support 2.Described axle sleeve 3 circumference are laid with radial blind holes or through hole 4, and interior graphite column 6 and the Compress Spring 5 of arranging of described blind hole or through hole 4, forms self oiling bearing thus.Described graphite column 6 and described blind hole or through hole 4 transition fit, like this, under the effect of Compress Spring 5, can remain the pressure contact of graphite column 6 and trailing arm roll shaft 1, axle sleeve 3 all the time in selflubricating state, and is only used in the graphite column more having renewed again after graphite column 6 has all worn away with trailing arm roll shaft 1, can save a large amount of graphite materials, also greatly extended the replacement cycle, the corresponding steel rolling manufacturing efficiency that improved.Described axle sleeve 3 adopts Cuprum alloy product, can effectively reduce the wearing and tearing of trailing arm roll shaft 1, avoids the scuffing of axle sleeve 3 and trailing arm roll shaft 1 surface of contact, extends working life and the service cycle of trailing arm roll shaft 1.Described graphite column 6 adopts transition fit with described blind hole or through hole 4, both axle sleeve 3 and the assembling with trailing arm roll shaft 1 thereof be convenient to, can guarantee that again graphite column 6 is constantly pushed out under the pressure of Compress Spring 5, and keep pressure contact between trailing arm roll shaft 1, guarantee the reliability of self-lubricating property.On described axle sleeve 3, blind hole can be set, also can be set to through hole 4, in the time being set to blind hole, be on axle sleeve, first to get out through hole, then the outer end in hole stopped up by closeouts, like this, can first complete the assembling of axle sleeve 3 and graphite column 6, Compress Spring 5, then integral press mounting enters bearing support 2; In the time adopting through hole 4, can now axle sleeve 3 be pressed fit into bearing support 2, then assemble again graphite column 6 and Compress Spring 5, using bearing support 3 internal circular surfaces as spring supporting.
