Abstract
The utility model relates to an alloy bearing block compensated with gray cast iron, which is characterized in that the alloy bearing block compensated with gray cast iron is formed by that the inner diameter of the bearing seat 1 of grey cast iron whose roughcast is cut is compensated with is an alloy layer 2. The alloy bearing block compensated with gray cast iron has easy manufacture, stable and reliable mechanical property, strong stiffness, abrasion resistance and duration.
Description
The utility model relates to a kind of parts, particularly grey cast iron compensator alloy bearing support that keep the engineering machinery operation.It mainly is that grey cast iron bearing support internal diameter sealing weld compensator alloy layer is realized.
As everyone knows, the parts grey cast iron bearing support that keeps dynamo-electric body operation both at home and abroad, when operation, the temperature variation that its internal diameter is produced is expanded with heat and contract with cold and the influence of mechanical vibration, cause ball bearing or roller bearing and bearing support surface of contact pine to become, make bearing walk the outer ring, bearing and axostylus axostyle string axle heating overtemperature liter, accelerate damage of bearings, cause complete machine and can not use and the shortening spreadable life.
Task of the present utility model just provides grey cast iron compensator alloy bearing support, can overcome above-mentioned deficiency, and the bearing support through this sealing weld compensator alloy reaches hardness, and is wear-resisting, and is good with bearing surface of contact tightness, the body stable and reliable operation, and the spreadable life is long.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a sectional view of the present utility model, and its structure such as Fig. 1 represent: 1, the dynamo-electric mechanical grey cast iron bearing support of various models, 2, ferronickel or low carbon steel sealing weld compensator alloy layer, 3, ball bearing or roller bearing, 4, bearing support (bearing) lid, 5, arbor;
Embodiment: when producing bearing support,, compensate 1～3 millimeter alloy-layer 2 with nife or low carbon steel sealing weld with the bad thickness that equals to want the sealing weld compensator alloy of grey cast iron bearing support 1 internal diameter cutting unhairing, grey cast iron compensator alloy bearing support.
The advantage of this alloy bearing seat: the hardness height, wearability is strong, and mechanical performance, tight ness rating are stablized, and the impact that not expanded with heat and contract with cold by variations in temperature is durable.
Claims (2)
1, a kind of grey cast iron compensator alloy bearing support is characterized in that bearing support 1 internal diameter has one deck ferronickel or low carbon steel compensator alloy layer 2.
2, by the alloy bearing seat of claim 1, the thickness that it is characterized in that compensator alloy layer 2 is 1～3 millimeter.
