我们车间600型钢带头上的一个传动齿轮是铸铁的,齿数158,模数3,转速155转/分,传动功率4千瓦。由于钢带被轧进齿轮之间,导致上述齿轮严重破坏,齿圈断裂五处(图1)。当时生产任务很紧,一时又找不到备件,加工新的齿轮,时间又很长。为此,我们对原齿轮进行了修补,仅用半天时间解决了问题。修复方法:1.将三段齿圈的断口(无牙齿的三个面)分别在砂轮机上或用锉刀 One of the transmission gears on the head of the 600-type steel shop in our workshop is cast iron with 158 teeth, a modulus of 3, a rotation speed of 155 rpm and a transmission power of 4 kW. As the strip was rolled into the gear, resulting in serious damage to the gear, ring gear fracture five (Figure 1). At that time, the production task was very tight, and at one time could not find the spare parts and processed the new gear, which took a long time. To this end, we repaired the original gear, only half a day to solve the problem. Repair methods: 1. The three ring gear fracture (three teeth without teeth) were on the grinder or file
