碟形弹簧由于结构紧凑,有较大的弹力,在机床行业得到广泛应用。 通常,在碟形弹簧的零件图上(见图1)除对上下端面标注平行度外,对其余参数基本上都无专门的要求。但是实践表明,为了使碟形弹簧具有均匀稳定的弹性和足够的使用寿命,在制造中除了要保证上下端面平行外,还应对其他一 Disc springs due to the compact structure, a larger stretch, widely used in the machine tool industry. In general, the parts of the disc spring diagram (see Figure 1) in addition to the upper and lower end surface marked parallelism, the rest of the parameters are basically no special requirements. However, practice shows that, in order to make the disc spring with a uniform and stable elasticity and sufficient service life, in addition to ensuring that the upper and lower end faces in parallel, but also to deal with the other one
