Abstract
The invention discloses a tinbased bearing alloy and preparing method, which comprises the following parts: 5.5-6.5 percent copper, 10-13 percent antimony, 0.3-0.8 percent zinc and tin. The preparing method comprises the following steps: putting 50 percent tin, all copper and antimony in the stove to fuse; adding all zinc after fusing at 500-550 deg.c; adding residual tin after the zinc is fused completely; stirring; stewing for 15-30 percent; casting at 360-450 deg.c.
Description
Technical field
The present invention relates to a kind of bearing metal and preparation method thereof, relate in particular to a kind of tinhase bearing metals and preparation method thereof.
Background technology
The high-speed bearing, the heavy lift high speed operation temperature that are applicable to automobile, tractor, steam turbine etc. are lower than 110 ℃ important bearing, for example: above high speed steam engine, the turbo-driven compressor of 360KW and the motor bearing more than the 880KW of 1400KW all adopts tin-based alloy basically, tin-based alloy has good characteristics such as higher antifriction performance, good imbedibility and friction conformability, but its intensity, hardness and fatigue strength are all lower.
Summary of the invention
The object of the present invention is to provide a kind of tinhase bearing metals and preparation method thereof, described tinhase bearing metals and preparation method thereof can solve its intensity of tin-based alloy of the prior art, hardness and all lower technical problem of fatigue strength.
The present invention provides a kind of tinhase bearing metals for solving the problems of the technologies described above, and wherein, described alloy includes copper, antimony, zinc and tin, and the weight percent of copper, antimony, zinc and tin is respectively in the described alloy,
Copper: 5.5%～6.5%,
Antimony: 10%～13%,
Zinc: 0.3%～0.8%,
Tin: surplus.
Further, containing weight percent in the described alloy is 0.05%～0.2% silver.
The present invention also aims to provide a kind of method of making above-mentioned tinhase bearing metals, described method is, earlier 50% weight of portions of tin, whole copper and whole antimony are put into the smelting furnace consolute together, after the fusing, in 500～550 ℃ of stoves, under the temperature, in stove, add the zinc of all wts fully, after melting fully, zinc in stove, adds remaining tin again, after all melting of metal is finished, stir and left standstill 15～30 minutes, be cast into ingot when temperature is between 360～450 ℃ in stove.
Further, in stove fully after the fusing, and before adding zinc, when temperature is between 500～550 ℃ in the stove, the adding weight percent is 0.05%～0.2% silver in stove at 50% weight of portions of tin, whole copper and whole antimony.
The present invention compares with prior art, and effect is actively significantly.Among the present invention, the adding of zinc has improved the intensity and the hardness of alloy, and zinc and copper form compound, and the zinc solid solution is in copper, can improve the intensity and the hardness of alloy, can dwindle solidification temperature range, improve liquidity, reduce dispersed shrinkage, reduce the gas content in the alloy liquid, reduce gas hole defect in the foundry goods.Simultaneously, the adding of silver has significantly improved the corrosion resistance nature and the antioxidant property of alloy, has improved the homogeneity of alloy, has improved the toughness and the intensity of alloy.
Bearing metal of the present invention is specially adapted to the high-speed bearing of automobile, tractor, steam turbine etc., and is applicable to that heavy lift, high speed operation temperature are lower than 110 ℃ important bearing, has improved the work-ing life of bearing greatly.
