摘　　要：研制的新型牙轮钻头轴承试验机由工作主机、可调式冲击泵、集成液压系统、注脂补偿系统、钻井液循环系统和电控电测系统等组成。试验机采用内摩擦副 (相当于钻头牙爪轴 )不动而外摩擦副 (相当于牙轮 )相对转动的运动方式 ;可试验相当于 2 15 90～ 311 15mm (8 ～12 英寸 )牙轮钻头轴承试件 ;采用液压加载 ,轴向和径向载荷、静载和动载可分别单独或同时施加 ;试验时可进行试验轴承温度、转速、摩擦力矩、钻井液压力和润滑脂压力等参数的动态测试。The newly developed simulation test system for tri-cone bit is made up of working mechanism, stepless regulated impulse pump, integrated hydraulic system, compensation system of lubricating grease, mud cycle system, and electric control and electric measure system. The test system adopts stationary internal frictional pairs and rotary external frictional pairs, and can make a test of bit bearing test pieces with a diameter of 215.90～311.15 mm. It adopts hydraulic loading, and axial and radial load, static load and dynamic load can be exerted respectively or synchronously. Dynamic test of such parameters as bearing temperature, rotary speed, friction torque, mud pressure and lubricating grease pressure can be made in the test.
