Abstract
The utility model discloses a wear-resistant, high temperature-resistant sliding bearing, which comprises an outer race and an inner race, the outer race is made of two layers of materials by a centrifugal casting technique, the outer layer of the outer race is ordinary carbon-structured steel, the inner layer of the outer race is manganese-molybdenum alloy, and is provided with two square grooves along the axial direction of the bearing, moreover, the two square grooves are symmetric relative to the axial line of the bearing, the groove width is not less than the width of the bearing, the inner race is made of two layers of materials by the centrifugal casting technique, the inner layer of the inner race is ordinary carbon-structured steel, and the outer layer of the inner race is manganese-molybdenum alloy. The sliding bearing is applicable to harsh working environments without oil and water and with high temperature, a great deal of dust, a large quantity of litters and the like, and has the advantages of high bearing capability, material saving and low cost.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of Wear-resistant, high-temperature resistant sliding bearing.
Background technique
The existing useful graphite of bearing that is applicable to the work under the rugged environment such as do not have oily, anhydrous, high temperature, dust is big, foreign material are many is done lubriation material, stud with the graphite post on the skin of design upper bearing (metal) inner ring, there are shortcomings such as complex structure, non-refractory in the type bearing; The employing specific alloy material monolithic manufacturing that also has forms, the disclosed high-sulfur alloy of Chinese patent ZL01208617.7 self-lubricating abrasion-resistant high temperature spherical bearing for example, the bearing of the type integral manufacturing can not make full use of material, cause the significant wastage of material, the cost height.
The model utility content
Technical assignment of the present utility model is at the deficiency in the above-mentioned technology, and a kind of Wear-resistant, high-temperature resistant sliding bearing is provided.
The technological scheme that the utility model technical solution problem is adopted is: a kind of Wear-resistant, high-temperature resistant sliding bearing, comprise outer ring and inner ring, and described outer ring is made by centrifugal casting technology by two layers of material, and the outer ring internal layer has two square grooves; Described inner ring is made by centrifugal casting technology by two layers of material.
The two layers of material of described outer ring, its skin is a carbon structural steel, internal layer is the manganese molybdenum alloy.
The two layers of material of described inner ring, its internal layer is a carbon structural steel, skin is the manganese molybdenum alloy.
The internal layer square groove of described outer ring is along the bearing axial direction, and two square grooves are about the bearing axis symmetry, and groove width is not less than bearing width.
The beneficial effect that the utility model can bring is:
One, bearing capacity is big, and it improves more than 20% than the bearing capacity of common rolling bearing;
Two, outstanding resistance to high temperature is arranged, can under 750 ℃ of high temperature, need not lubricate and reliably working;
Three, friction factor is little, is generally f=1.1～0.05 according to its friction factor of use condition;
Four, operating rate is higher, can be under the situation of V＜6m/s stable operation;
Five, traditional lubricated, cooling system be can omit, equipment investment and repair and maintenance work reduced;
Six, save material, cost is low.
