Definitions

the invention relates to a copper alloy based on copper-tin for the production of semi-finished or finished components by continuous casting and subsequent mechanical processing. Moreover, the invention relates to a method for producing a semifinished product or component from a copper-tin-based copper alloy, wherein the copper alloy is continuously cast, then the strand sawn and made of the strand pieces by machining a semifinished product or a finished component.
the worm wheel is often made of copper-tin-based copper alloy, that is, a bronze alloy, in order to achieve good sliding properties of the worm wheel and thus to provide a low-noise worm gear.
Low noise results from a high proportion of Gleit stiilzambaen, with high sliding velocities with relatively high flank pressure presupposing material combinations suitable for use. This is achieved for example by a hard-soft combination of materials.
the present invention to provide a copper-tin-based copper alloy, which enables the production of components, such as worm wheels, with a longer service life with simultaneous low-noise of the transmission.
the invention has the object to provide a method for producing semi-finished or finished components of a corresponding copper alloy.
the Sn content of the copper alloy according to the invention leads to finely divided, very hard and Sn-rich microstructural constituents, which contribute significantly to increasing the wear resistance.
the Sn content enables an improvement in the toughness properties of the copper alloy according to the invention to be achieved via a heat treatment.
a strength and hardness increase is achieved via the nickel content of 1.5 to 2.5% by weight, without adversely affecting the machinability.
the relatively low lead content of less than 0.3 wt .-% ensures that only small amounts of lead are released in the abrasion.
the phosphorus content of 0.05% by weight to 0.40% by weight improves the castability of the copper alloy according to the invention in the continuous casting process.
the copper alloy according to the invention comprises 84.5% to 87.5% copper. Limiting the levels of antimony, sulfur and zinc to a total of no more than total 0.5 wt.%, The upper limits for antimony being 0.10 wt.%, For sulfur being 0.05 wt.% And for zinc being 0.40 wt.%, Ensures that the improved wear properties of the Copper alloy according to the invention are not deteriorated.
the above-described object is achieved by a generic method for producing a component from a copper alloy according to the invention in that before casting the content of the copper melt of phosphorus and zirconium by alloying zirconium-copper and phosphorus-copper Pre-alloys is set, the The zirconium is alloyed with a Zr-Cu master alloy with 67% Cu and 33% Zr content and the alloying of phosphorus with a P-Cu master alloy with 90% Cu and 10% P content.
the specified master alloys allow a particularly accurate adjustment of the contents of zirconium and phosphorus in the copper alloy according to the invention and thus allow precise control of the microstructure.
a particularly economical method for producing a component from a copper alloy according to the invention results according to a next embodiment of the method according to the invention in that the removal speed during continuous casting is greater than 50 mm / min, preferably greater than 80 mm / min.
the peel rate depends on the diameter of the strand and therefore the amount of metal to be cooled, with the copper alloy according to the invention, however, an increase in the peel rates of copper-tin-based copper alloy could be achieved without having to compromise on the structural quality.
a microstructure with a grain size of around 60 ⁇ m is achieved.
solid rods or tubes up to a diameter of 200 mm, preferably 180 mm are produced by the continuous casting. These dimensions allow for sufficient peel-off speed and allow the production of finished blanks from sawn blanks without the need for very large amounts of waste.
the tubes can have both a circular cross section and a square, hexagon or a polygonal cross section.
worm wheels of a worm gear or semifinished products for the production of worm wheels are produced by worm gears.
Worm wheels of a worm gear made from the copper alloy according to the invention are not only quiet in their use in drive technology, but also have a particularly good wear resistance. This leads directly to an extension of the life of the equipped with the corresponding worm gears drives.
the copper alloy was continuously cast at a casting temperature of 1150 ° C to 1250 ° C in a graphite mold. With a peel rate of about 85 mm / min. a pipe was drawn with an outer diameter of 120 mm and an inner diameter of 70 mm. Subsequently, the continuously cast pipe was sawed into pieces of strands and further processed into semi-finished products for the production of worm wheels. It was found that the worm wheels produced from the copper-tin-based copper alloy according to the invention were particularly wear-resistant and nevertheless have the good running-in properties of conventional worm wheels made of conventional copper-tin-based copper alloys.
the grain sizes were in the range of 60 microns and are similar to the centrifugal casting evenly from ⁇ -substitution crystals together with ⁇ phases embedded in the grain boundaries. It is assumed that this microstructure is responsible for the good shrinkage properties and wear properties.
the copper alloy according to the invention compared with the known copper alloy CuSn12Ni according to DIN standard DIN EN 1982, approximately 15% improved values with regard to the tensile strength RP0.2 and the elongation A 5 were achieved. This improvement in mechanical properties is due in particular to the optimized microstructure. As a result, a significantly extended life, for example, a worm wheel sets.
