摘要:

本文介绍了一套测试装置,用以测试钻头在大钻压下任意转速的牙齿受力经过试验,证明该装置的设计是成功的。我们在钻头试验架上,按规定钻头转速,变动钻头钻压,作了多种工况下的牙齿受力测试。通过对大量的实验数据的处理与分析,获得了在大小钻压下钻头牙齿上的载荷变化规律。

Abstract:

This paper has introduced a set of test device to examine the loads on teeth of the bit at different rotary speed and under high bit-weight, The design of the test device has been proved to be successful through testing. The writer has completed many kinds of tests of loads on teeth of the bit at proper rotary speed and under different bit-weight. Some laws of change in load on bit teeth under low to high bit-weight have been found by processing and analyzing a great many test data.

Key words: Cone bit, Load on teeth of the bit, Test device, Test
