在我厂生产的北京型2700马力液力传动客运内燃机车中,为了提高某些齿轮(如:液力传动箱中的油泵齿轮、换向齿轮、惰性齿轮等)的加工精度、光洁度和疲劳强度,在齿轮精加工过程中用自制的塑料珩磨轮对齿轮进行珩齿精加工。 140多台北京型液力传动内燃机车的长期运用证明,齿轮运转情况良好,使用寿命长。用塑料珩磨轮进行珩齿精加工与磨齿工艺相比,还具有效率高、质量好等优点。为了取得较好的珩磨效果,必须制造优质的塑料珩磨轮。制造塑料珩磨轮的关键在于合理的配料成份和制作工艺。
In our Beijing-based 2700 horsepower hydraulic transmission passenger diesel locomotive, in order to improve the machining accuracy, finish and fatigue strength of some gears (such as oil pump gear, reversing gear, inertia gear, etc.) , In the gear finishing process with homemade plastic honing wheel gear honing finishing. Long-term use of more than 140 Beijing-type hydraulic drive diesel locomotives proved that the gears are in good working condition and long service life. Honing the plastic honing wheel with gear grinding process, compared with high efficiency, good quality and so on. In order to achieve a better honing effect, we must create high-quality plastic honing wheel. The key to making a plastic honing wheel is a reasonable ingredient composition and manufacturing process.
