一、摘要本专利涉及轧辊磨床的一套换向机构,该换向机构有一组与砂轮架拖板运动同步而缩小了的换向部件。换向机构由纵向排列的挡铁执行,根据挡铁所在位置在运行中使运行电动机和拖板换向。每个挡铁与手动调节的丝杆相联,以决定由换向机构所代表的拖板行程区域。有个齿轮同时与两挡铁调节丝杆啮合,齿轮上装有一对无触点行程开关及其他信号装置,该
First, this patent relates to a set of roll grinder reversing mechanism, the reversing mechanism has a group of retractable components and the carriage frame synchronized with the reduction of the movement. The reversing mechanism is carried out by longitudinally arranged stoppers, which commutates the running motor and the carriage according to the position of the stop iron. Each stop iron is connected to a manually adjusted screw to determine the carriage travel area represented by the reversing mechanism. A gear at the same time with the two block iron screw rod, the gear is equipped with a pair of contactless switch and other signaling devices, the
