摘要:

在对盘式钻头齿圈失效机理分析的基础上,提出了齿圈表面堆焊耐磨合金强化方法和镶嵌硬质合金齿圈强化方法,通过试验研究和对比分析,确定了冶金混合烧结固齿法镶嵌硬质合金齿圈强化盘式钻头。进一步的试验研究表明:采用冶金混合烧结固齿法镶嵌硬质合金齿圈来强化盘式钻头齿圈,其结合情况非常好;硬质合金齿圈的硬度、耐磨料磨损的能力和耐冲击磨料磨损的能力在烧结后都有进一步的提高,说明采用冶金混合烧结固齿法镶嵌硬质合金齿圈来强化盘式钻头齿圈是可行的。

Abstract:

Based on analyzing the failure mechanism of the gear-rim of disk bit, the strengthened methods of the antifriction alloy welded on the surface of the gear-rimand hard-alloy gear-rim inlayed. By experimental study and contractive analysis, the disk bit is strengthened through inlaying gear-rim of hard alloy, it was determined to use sintering metallurgy blender to fix teeth for the strengthened disk bit inlaying gear-rim of hard alloy. Because the result of further experimental study show that the combined situation of gear-rim and bit is very good. After being sintered, the hardness of the gear-rim of hard alloy, the ability of antifriction of abrasion and impact attrition of abrasion was improved. It is available that disk bit is strengthened through inlaying gear-rim of hard alloy by means of sintering metallurgy blender to fix teeth.

Key words: disk bit, gear-rim, strengthen, experimental study
