An Approach to Measuring No-Load Rotational Torque of Self-Lubricating Spherical Bearing in Rolling Clearance Pro-cess

摘要: 滚轧游隙是自润滑关节轴承调节无载启动力矩的一种工艺手段。在建立滚轧中被轧轴承的摩擦力矩关于滚轧力的双线性模型的基础上，提出了通过连续检测滚轧加载过程或卸载过程中被测轴承的摩擦力矩和相应的滚轧力，进行无载启动力矩的在线检测的方法。本文提出的方法有助于提高自润滑关节轴承滚轧游隙的精度。

Abstract: Rolling clearance is a type of means of adjusting the no-load rotational breakaway torque of a self-lubricating spherical bearing. Based on the bilinear model of rotational torque vs. rolling force in the rolling process, a method to evaluating the no-load torque is present, by detecting the variations in the rotational torque with the rolling force during the uploading or unloading stage in the process. The method proposed in this paper helps to improve the accuracy of rolling clearance of self-lubricating spherical bearings.
