为了使高铝锌基合金更加广泛地应用到生产实际从而转化为生产力，本论文致力于将本课题组研制出的PZA27新型高铝锌基合金在齿轮传动方面的应用研究。其主要内容包括：可行性预测，齿轮试件的制作。试验台的设计与制造，试件的跑合和磨损试验以及结果分析等五大部分。自行设计的试验台操作简单、测试手段方便，适用于不同转速、不同载荷条件下的齿轮运转试验，其性能优良，符合本试验的使用要求。作者在对铸态下的PZA27、ZA27合金的机械性能、减摩耐磨性能、机加工性能、经济效益等各个方面进行充分地分析论证，同时将其与常用作高、中等负荷下齿轮的ZQSn6-6-3、ZQA19-4和ZHMn58-2-2等铜合金材料在这些方面进行比较之后，发现PZA27合金的各方面性能比上述铜合金优越，有望代替这些钢合金用于齿轮传动，然后对PZA27、ZA27合金进行低、中速逐级加载条件下的齿轮传动运转试验。实验结果表明：在低速重载条件下，PZA27合金齿轮试件的磨损量基本上在标准规定的范围之内，轮齿表面的磨损形式也为齿轮运转过程中出现的表面擦伤，是一种良好的低速重载下的齿轮材料；PZA27合金的耐磨性高于ZA27合金，机加工性能好，可以代替上述铜合金用作相同工作条件下的齿轮传动；PZA27合金不同材质齿轮副（45钢／PZA27合金）?
In order to make the high-Al-Zn-based alloy more widely applied to the production and thus to the productivity, this thesis is devoted to the research on the application of PZA27 new high-Al-Zn-based alloy in gear transmission. The main contents include: feasibility prediction, gear test pieces. Test-bed design and manufacturing, running the specimen and wear test and analysis of the results of five major parts. The self-designed test rig has the advantages of simple operation, convenient testing means, suitable for gear running test under different rotational speed and different load conditions, and has excellent performance and meets the requirements of the test. The authors fully analyze and demonstrate the mechanical properties, friction and wear resistance, machinability and economic benefits of PZA27 and ZA27 alloys under the condition of as-cast, and compare them with those of ZQSn6 -6-3, ZQA19-4 and ZHMn58-2-2 and other copper alloy materials in these areas were compared after the PZA27 alloy found in all aspects of performance superior to the above copper alloy is expected to replace these steel alloys for gear drive, and then PZA27, ZA27 alloy for low, medium-speed loading condition of the gear drive running test. The experimental results show that under the conditions of low speed and heavy load, the wear amount of PZA27 alloy gear specimen is basically within the standard range, and the wear form of gear tooth surface is also a surface abrasion occurring during gear running Good low-speed heavy-duty gear material; PZA27 alloy wear resistance is higher than the ZA27 alloy, machinability, can replace the above copper alloy for the same working conditions of the gear drive; PZA27 alloy gear of different materials (45 steel / PZA27 alloy)?
