摘　　要：为解决垂直轴线方向大载荷下的小扭矩测量问题,通过在传感器两端布置成对安装的轴承,设计了一种可承受重载的扭矩传感器,基于测量原理分析和强度计算,确定了传感器结构尺寸。对传感器负载工况下变形与普通传感器变形进行了有限元分析。结果表明,所设计的两端双轴承支承结构能够减小弯矩对传感器扭转轴的影响,传感器满足大重力负载下的小扭矩测量要求。To solve the problem of measuring small torque companied with large lateral force,a torque sensor with paired bearings on both ends that can withstand heavy duty is designed.The dimensions of the sensor are defined based on measuring theory analysis and structural strength calculation.The deformation of the designed sensor under load is compared with that of the common senor through finite element analysis.The results show that the paired bearing structure can reduce the influence of the bending moment on the torque shaft,and the sensor can be used to measure small torque companied with large force.
