我厂用可调式连杆机构在滚齿机上加工鼓形齿轮,操作方便,加工质量稳定。滚齿时,只要调整好连杆AB的长度(L_(AB)),就能加工出不同规格的鼓形齿轮。结构与安装(1)结构(图1):进刀机构由进刀丝杠1、底座3和滑动接头4组成。水平调节连杆由接头9和调节螺栓7组成,轴5、10上都装上滚动轴承,使连接处灵活,并可减少机构的间隙。垂直可调连杆由上连杆14、下连杆12和调节螺栓13组成。(2)安装:先将滚齿机工作台下的水平进刀丝杠折除,装上可调式连杆机构。连杆机构的底座3固定在工作台拖
I plant with adjustable linkage in the hobbing machine processing drum gear, easy to operate, processing quality and stability. When gear hobbing, just adjust the length of the connecting rod AB (L_ (AB)), can produce different specifications of the drum gear. Structure and Installation (1) Structure (Fig. 1): The feed mechanism consists of feed screw 1, base 3 and sliding joint 4. The leveling rod is composed of the joint 9 and the adjusting bolt 7, and the rolling bearings are mounted on the shafts 5 and 10 to make the joint flexible and reduce the gap of the mechanism. The vertically adjustable connecting rod is composed of an upper connecting rod 14, a lower connecting rod 12 and an adjusting bolt 13. (2) Installation: First gear hobbing table horizontal infeed screw dismantling, fitted with adjustable link mechanism. The base 3 of the linkage mechanism is fixed on the workbench
