电度表上的传动件——蜗杆,表面质量要求很高。齿面有较小的毛刺或光洁度不好时,会导致运转中发生齿跳或轻载不转等疵病。机械去毛刺和机械抛光,既费工而且齿面上的小毛刺不易去净,光洁度也达不到要求。用电解法去毛刺并抛光,工效高、去毛刺的效果好,表面光洁度能提高1～2级。 Transmission on the meter - worm, the surface quality requirements are high. Tooth surface with a small burr or poor finish, it will lead to the operation of tooth jump or light load does not turn and other flaws. Mechanical deburring and mechanical polishing, both labor-intensive and small burr on the tooth surface is not easy to go to the net, the finish does not meet the requirements. Burr and electrolytic polishing method, high efficiency, deburring effect, the surface finish can improve 1 to 2.
