it was proved by theories and experiments that the load capacity of double circular arc spiral bevel gearing is higher than involute gearing「s.
实践证明,双圆弧弧齿锥齿轮传动具有比渐开线齿轮传动高得多的承载能力。
efficient, long-life helical and helical bevel gearing means these units use less energy, run cooler and last longer than typical single-worm gear units.
