Abstract
The utility model relates to a self-lubricating wear-resistant roller structure of a sintering pallet, which comprises a bushing mounted on an axle of the sintering pallet, a roller collar and a roller assembled with the bushing. The self-lubricating wear-resistant roller structure is characterized in that the bushing comprises a bushing body made of 45# steel, an embedding hole is arranged on the bushing body axially, a self-lubricating solid material capable of realizing lubricating effect is embedded in the embedding hole, the roller collar comprises an annular body made of 45# steel, a plurality of embedding holes are disposed on the annular body axially, and self-lubricating solid materials capable of realizing lubricating effect are embedded in the embedding holes. The self-lubricating wear-resistant roller structure has the advantages that the self-lubricating wear-resistant roller structure can bear load as steel has high mechanical strength and fine heat conduction, the lubricating solid materials are easy to be shorn, slipped, condensed and attached, and the lubricating materials can be uniformly coated on a sliding work surface by utilizing obvious difference of elastic aftereffect of rigid substances and plastic substances and different thermal expansion coefficients of the rigid substances and the plastic substances so as to lubricate the roller, the bushing and the roller collar, thereby prolonging service life of the roller of the sintering pallet.
Description
Technical field
The utility model belongs to iron and steel metallurgical industry agglomerating plant field, particularly relates to a kind of pallet self-lubricating abrasion-resistant roll structure.
Background technology
Pallet not only will bear the weight of self, the weight of grid section and the weight of sintering deposit in whole sintering process, also will stand the effect of long-term alternating thermal stress, and condition of work is very abominable.The motion of pallet promotes the chassis roller by the active star-wheel and realizes, every chassis all has 4 rollers, be installed in the inboard of wheel, when stirring roller, roller not only will bear the weight all on the chassis and the effect of alternating thermal stress, but also will bear in the impulsive force at bend place end to end, cause the axial float of roller and axle bush, cause the axle bush distortion in the chassis roller when serious.The collars 3 of chassis roller in the prior art, axle bush 5 and collars 6 are made for ZCuAl10Fe3 cast copper alloy material, see also Fig. 1.ZCuAl10Fe3 cast copper alloy wearability and corrosion resisting property are good, but it is relatively poor to be hit, and easily cause the chassis roller often to damage.Because the mode of the lubricated employing filling calcium-base grease between roller and axle bush, the heat of trolley body can be by conduction and radiation delivery to wheel in the sintering process, makes the temperature of wheel be much higher than the normal serviceability temperature of plain oil.Lubricating grease will evaporate, oxidation, cracking and lose lubrication with this understanding, thereby influence the normal operation of roller, shorten the service life of axle bush.Because pallet work is in the reciprocating motion all the time the time, under halt condition not, wheel is refueled very difficulty, not allow pallet often to stop be that wheel refuels and produce, so cause the insufficient lubrication of roller.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of have wear-resisting, support strength is high and the pallet self-lubricating abrasion-resistant roll structure that can prolong its service life.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: pallet self-lubricating abrasion-resistant roll structure, comprise axle bush, collars that is installed on the pallet axletree and the roller that assembles with axle bush, it is characterized in that: described axle bush comprise adopt the 45# steel to make the axle bush body it is shaped on inlaid hole on axially, in inlaid hole, be embedded with the self-lubricating solid material that can play lubrication; Described collars comprises the ring bodies that adopts the 45# steel to make, and has several inlaid holes on ring bodies is axial, is embedded with the self-lubricating solid material that can play lubrication in its inlaid hole.
The utility model can also adopt following technical scheme:
Described self-lubricating solid material is a wm alloy solid self-lubricating material.
Inlaid hole diameter on described axle bush body and the ring bodies is 5-15mm.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly on metal base with certain physics, chemical attribute, certain proportion by projected area, along the mode of the direction of motion with overlapping covering, inlay through special kollag, and a kind of composite solid self-lubricating material parts that form.Relative motion and friction process in taking place in the friction pair of this parts, because the mechanical strength height of base material (as iron, steel etc.), heat conductivity is good, thereby plays a part bearing load; And the characteristic that the lubricated solid material that embeds has the shearing of being easy to generate, slippage, condenses, adheres to, and can utilize the significant difference and the different characteristics of the two thermal coefficient of expansion of rigidity material and ductile material elastic after effect, thereby can make friction pair in the relative motion process, its lubriation material can be coated on the working surface of slip equably.Through repairing change, more living repeatedly, generate solid lubricant film, thereby reach antifriction, wear-resisting, effect that bearing strength is high, prolonged the service life of chassis roller.
