钢的性能及生产工艺技术。结构钢包括碳素结构钢和合金结构钢,用于制造金属结构及机器设备。韧性和良好的加工性。合金结构钢约含5%以下的合金元素和0.6%以下的碳。近30年来,金钢(HSLA或微合金化钢)性能和产量得到了很大的发展,代替结构钢用于焊接、铆接和螺栓结构上,还用来做调质和非调质机器零件。美国将高强度低合金钢列入合金结构钢。合金结构钢是合产量高、牌号多的钢类,中国标准为GB/T3077—1999。艺特点和使用性能,钢、超高强度钢、弹簧钢和轴承钢。由于后两者具有各自的独特的性能,通常作为独立钢类,类钢称为合金结构钢。近年来,用以制造齿轮的结构钢被特殊冠名为齿轮钢(特别是合金结构钢,Cr-Mo系列、Mn-Cr系列、Cr-Ni-Mo系列等钢种)。

橡胶是通用的密封材料,它是由和丁二烯合成的橡胶,对以下介质有良好的抵受能力。一般的燃料,橡胶密封件还允许轴承在无油的情况下短时间运行。允许的工作温度范围为-40至100℃。短时间内可以承受高达120℃的温度。但不宜在更高的温度下运行,因为橡胶将会硬化。氢化橡胶比橡胶有更加的耐磨特性,因此用这种材料制成的密封件具有更长的工作寿命。此外,氢化橡胶在热油或臭氧中有更强的抗热、抗老化和抗硬化的能力。氢化橡胶允许高的工作温度为150℃,比橡胶的工作温度高出很多。氟橡胶主要的特性是耐高温和耐化学腐蚀,并有很好的抗老化和抗臭氧的性能,而且渗气度也非常低。即使在非常恶劣的工作条件下,氟橡胶仍然有优异的耐磨性。它能承受200℃或以下的工作温度。约达到90~100万t。20Cr、40Cr、28MnCr5(德国牌号Mn-Cr系列钢种)、SAE8620H(美国牌号Cr-Ni-Mo系列钢种)。标准执行GB/TGB/T。我国车辆齿轮用钢采购技术标准已出台。(协议)提出下列必须满足的6项条件:1)末端淬透性:淬透性带宽(上限减下限)不能超过7HRC。氧含量≤0.0030%。3)非金属夹杂物:A类细系、粗系≤2.5级;B类细系、粗系≤2.5级;粗系≤2.0级;D类细系、粗系≤2.5级。4)奥氏体晶粒度细于或等于5级。5)表面质量符合GB/T《合金结构钢》的规定。的规定。汽车齿轮钢属结构钢,其中以合金结构钢为主,渗碳齿轮钢比例在不断扩大,种类型的齿轮钢。
