杠杆齿轮式百分表测量杆与轴的连接如图 1所示。测量杆 8的装配部分 (以下文中称大圆 )的轴孔上端有开口槽 (槽宽 0 .5ｍｍ) ,孔靠大圆材料的张力与轴5摩擦连接 ;杠杆长臂 4装在轴 5的肩部与测杆 8的中间。它们之间的相互扭力为 3Ｎ～ 8Ｎ。拆卸时 ,双手分别拿住测量杆与杠杆长
Lever gear dial indicator rod and shaft connection shown in Figure 1. Measuring rod 8 assembly part (hereinafter referred to as large circle) shaft hole at the upper end of the opening slot (slot width 0.5mm), the hole by the large circle of material tension and friction shaft 5; lever arm 4 mounted on the shaft 5 shoulder And the middle of the measuring rod 8. The mutual torque between them is 3N ~ 8N. When disassembling, hold hands and lever separately with both hands
