Abstract
The utility model provides a thin-wall oil film bearing for a high-speed wire mill. The thin-wall oil film bearing comprises bearing bushes and a linings and includes two uniform semicircular structures. Each semicircular structure comprises the bearing bush and the lining, with the inner surface being provided with a groove. One of the semicircular structures is provided with an oil inlet and an oil outlet. Two ends of the oil film bearing are sintered, so as to prevent the bearing bushes from coming off. The bearing bushes are made of special alloy pipe materials mainly comprising mixtures of steel, copper-lead alloys and babbit metals, and the linings are made of low-carbon steels. The thin-wall oil film bearing of the utility model has the beneficial effects that through combination of different materials, the thin-wall oil film bearing maintains the characteristics of high bearing capacity, wear resistance, erosion resistance and long service lifetime and also the manufacture cost is reduced.
Description
Technical field
The utility model belongs to high-speed rod and produces the element part field, is specifically related to a kind of high-speed wire mill thin-walled filmatic bearing.
Background technology
Filmatic bearing is the important spare part of high-speed rod-rolling mill, and high-speed rod-rolling mill manufacturing machine transmission complicacy, processing and assembly precision are high, speed is fast, require filmatic bearing to have good bearing capacity and thermal diffusivity.As the major part of milling train, many steel mills can't carry out activity in production in continuous high-efficient ground because of the damage of filmatic bearing.Filmatic bearing in the past adopts whole heavy wall type filmatic bearing usually, and the alloy-layer of being poured into a mould is easy to generate the aciculiform pore, and blank is generally other unit and provides, and purchase cost is high, and passing rate of processing is low.
Summary of the invention
The purpose of the utility model provides a kind of high-speed wire mill thin-walled filmatic bearing, keeping the high performance while, reduces production costs.
The technical scheme of the utility model is: a kind of high-speed wire mill thin-walled filmatic bearing comprises bearing shell and lining.
High-speed wire mill thin-walled filmatic bearing is divided into uniform two semicircular structures, and each semi-circular structure all comprises bearing shell and lining, and inner surface also is provided with a groove, and one of them semi-circular structure parts is provided with fuel feed hole and oil outlet.
Bearing shell is positioned in the lining, is made by special metals pipe material, and main material is the mixture of steel, Pot metal and babbit; Lining is that mild steel is made.
The two ends bearing shell of filmatic bearing and lining are bonding through sintering processes, prevent that bearing shell from deviating from.
The benefit of the utility model is: this filmatic bearing has adopted the branch body structure, adopts the conventional thin sheet alloy, through the punch process moulding.Bearing is pressed in the lining, and the both ends of the surface welding is integrally formed with steel backing.The alloy plate is to form through the sintering compacting, the no any defective in surface, and no aciculiform pore behind the processed finished products, reaching the standard grade to use meets the requirements.The utility model has reduced the wall thickness of filmatic bearing, is keeping bearing capacity high simultaneously again, the characteristics of wear resistant corrosion resistant and long service life, and because the change of material, cost can reduce by 70%.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Fig. 2 is the cutaway view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, high-speed wire mill thin-walled filmatic bearing comprises bearing shell (1) and lining (2), and bearing shell (1) is positioned at lining (2) lining, and material is for being the mixture of steel, Pot metal and babbit; The material of lining (2) is a mild steel; Bearing shell at filmatic bearing two ends (1) and lining (2) sintering prevent that bearing shell (1) from coming off.
As shown in Figure 1, high-speed wire mill thin-walled filmatic bearing is divided into two semicircular structures, and one of them semicircular structure is provided with fuel feed hole (4) and oil outlet (5), in the inboard of filmatic bearing, is provided with a groove (3), for linking up the usefulness of lubricating oil.
As shown in Figure 1, when roll shaft when the direction of arrow is rotated, lubricating oil gets into from fuel feed hole (4); Link up along groove (3); Form one deck oil film at bearing shell (2) inner surface, play lubrication, lubricating oil unnecessary or that used is then discharged from oil outlet (5).
Through above enforcement, utilize mild steel to replace alloy and make lining (2), when keeping bearing performance, also reduced production cost.
More than specifying is the preferred embodiment of the utility model; This embodiment is not the claim in order to restriction the utility model; Allly do not break away from equivalence enforcement or distortion, the improvement etc. that the utility model is done, all should be included within the protection domain of the utility model.
Claims (2)
1. high-speed wire mill thin-walled filmatic bearing comprises bearing shell and lining, it is characterized in that: high-speed wire mill thin-walled filmatic bearing is divided into uniform two semicircular structures, and each semi-circular structure all comprises bearing shell and lining, and inner surface also is provided with a groove.
2. high-speed wire mill thin-walled filmatic bearing according to claim 1 is characterized in that: the two ends bearing shell of said filmatic bearing and lining are bonding through sintering processes.
