每当汽车刹车更换新蹄片或长期使用造成蹄片偏磨时,就需要对蹄片外圆进行一次加工,以便恢复良好的刹车性能。我们自制了结构简单的手摇光圆工具,使用方便而效果好。工作原理工具是根据外啮合行星齿轮机构原理设计的(图1),中心轮(Z_1=25)用联接螺母把它与汽车(前轮或后轮)的半轴套联为一体,并以半轴套为定 Whenever the car brakes to replace the new shoe or wear long-term use of the shoe eccentric wear, you need a cylindrical outer diameter of the shoe in order to restore good braking performance. We made a simple structure hand round light tool, easy to use and effective. Working principle The tool is based on the principle of an externally-meshed planetary gear mechanism (Figure 1). The center wheel (Z_1 = 25) is bolted to the axle sleeve of the car (front or rear wheel) Sleeve is fixed
