精密蜗轮副,是精密设备上分度的重要元件之一,随着机械工业和国防工业的发展,对分度元件的分度精度提出了更高的要求。为适应生产上的需要,在厂党委的的领导下,由技术科和齿轮车间,组成了一个“三结合”班子,共同研究在滚齿机上采用珩磨工艺,制成了如图1、图2所示的“珩磨装置”。经几年实践证明,蜗轮副经珩磨后,齿面光洁度达(?)8以上,精度为5级,接触斑点:齿高和齿长分别稳定在65％和75％。
Precision worm gear, precision equipment is an important component of the indexing, with the development of machinery industry and national defense industry, indexing device indexing accuracy put forward higher requirements. In order to meet the needs of production, under the leadership of the factory party committee, the technical department and the gear workshop formed a “three-in-one” team to jointly study the use of honing machine hobbing technology, made of Figure 1, Figure 2 Honing device shown. After years of practice, it has been proved that after the honing of the worm gear pair, the tooth surface finish (?) Is over 8, the accuracy is 5, and the contact spots are stable at 65% and 75% of tooth height and tooth length respectively.
