Development of Low-generated Heat Plastic Materials for Gears

塑料材料广泛用于齿轮和机械零件。当塑性材料受到水平载荷作用时，预计很快就会恢复一个小时以上的应力。这是这些应力能在塑料材料内部的积累。这种应力能被转化为热能。这是基于磁滞损耗产生的热。描述了应变与热能之间的关系，建立了基于模拟的合金塑料磨损模型。根据滞回损失计算了8种塑料材料产生的热量。在干燥条件下，将计算值与实验值进行了比较。在模拟结果的基础上，开发了几种新材料，即小时合金塑料、油的聚缩醛含量、聚丙交酯、聚酰胺-66和玻璃纤维的聚缩醛含量。注塑齿轮就是用这些塑料材料制造的。这些齿轮是超级齿轮(模数：1，齿数：30/60，压力角：20齿宽：5 mm)。在实验中，对吸收和循环两种系统运行试验台进行了改造，并进行了运行试验。试验项目包括磨损试验、误差试验、温度试验和噪声试验。试验结果导致了一些低产生热量的塑料材料、开发和一些设计所需的数据，预计将有广泛的应用，特别是在齿轮上。

The plastic materials are lot of used for gears and mechanical elements. When the plastic materials are given by action of horizontal load, stress is expected to be resumed shortly taken an hour over. This is accumulation of these stress energes inside the plastic materials. This stress energy is changed the thermal energy. This is the generated heat that based on hysteresis loss. This paper described the relation between strain and thermal energy.The alloy plastics wear based on simulations, were developed. The eight plastic materials were calculated regarding heat generated based on the hysteresis loss. The calculated values were compared with experimental in dry. The results led to a low-generated heat plastic material in dry.Those new materials based on results of simulation were developed, this is to say, hour kinds of alloy plastics, Polyacetal content of oil, Polyaceta, Polyamid-66 and Polyacetal content of glass fiber. Injection molded gears were produced by those plastic materials. Those gears are super gears (module ; 1, number of teeth : 30/60, pressure angle : 20 tooth width : 5mm). In the experiment, the two system running test machines of absobed and circulated were remodeled and running test is experimented. The items of test are wear, error, temperature and noise tests in the total revolutions 10.The results lead to some low generated heat plastic materials, development and some necessary data for the design and are expected to have a wide range of applications especially for gears.
