摘要
为改进现有牙轮钻机要用链条加压的结构，解决链条加压钻机在工作中经常发生跳链的问题，提高国产牙轮钻机的技术水平，应用国外先进的无链加压牙轮钻机的技术，研制了适合我国国产牙轮钻机特点的无链加压装置。
To improve the structure of the existing chain pressurized rotary drills,to solve the problem of chain skipping that often occurs in their operation and to raise the technological level of the home made rotary drills,a chainless pressurzing device that is suitable to the characteristics of the home made drills was developed by appling the advanced foreign technology of chainless pressurized rotary drills and has been successfully used in a home made YZ 35 rotary drill.
