摘　　要：该文研究的是一种新型的基于同步齿型带的差动直线运动机构.该机构是在传统的同步带机构的主、从动轮之间加上一套由大小不同的两个同轴固联在一起的差动轮组成的差动传动机构.当主动轮转动时,由于大小差动带轮的直径不同,差动机构就不会停留在原处,而会以一定的规律移动.该文对此机构的传动机理进行了研究,推导出一套传动关系.同时,我们应用这些传动关系研制的一维线性驱动器验证了基本的传动原理,为该理论的进一步应用研究打下了良好的基础.This paper studies linear actuators based on differential motion of timing belt pulley. In this mechanism, two co-axial pulleys with different diameters are fixed between the driving pulley and the idler pulley in a traditional timing transmitting system. When the driving pulley rotates, the axis of the differential mechanism will move due to the different diameters of the differential pulleys. To verify the theories, a cell using this mechanism has been developed successfully. This paper presents the new mechanism, a series of theories and the experimental equipment. All these form a base for further application research.
