汽车后桥从动齿轮(即盘形齿轮)由于形状不对称,热处理时变形较大,对于大型从动齿轮,即使使用淬火压床也难达到百分之百的合格,笔者在长期的生产实践中采用火焰校正法校正变形超差的齿轮获得成功,可以使全部超差齿轮校正合格。这就使没有淬火压床的非专业齿轮生产厂,同样可以生产螺旋伞齿轮,得到合格产品。一、变形规律及要求影响螺旋伞齿轮变形的因素是很多的,如原始组织、正火情况、渗碳的
The rear axle driven gears (ie, disc gears) of the rear axle of the automobile are greatly deformed due to the asymmetric shape and heat treatment. For large driven gears, it is difficult to achieve 100% pass even if the quenching press is used. The author adopts flame in long-term production practice Correction method to correct deformation tolerance gear success, you can make all the tolerance correction gear. This enables non-specialized gear manufacturers without a quench press to produce a helical bevel gear as well, resulting in a qualified product. First, the law of deformation and requirements Helical bevel gear deformation is a lot of factors, such as the original organization, normalizing conditions, carburizing
