我局于去年8月革新成功一台手摇式轮胎拆装机,操作情况如图1。本机结构简单,整机机架均采用10号槽钢焊接而成,齿轮和轴都采用45号钢。减速机构由四个直齿轮组成:一轴小齿轮24齿,二轴大齿轮32齿、小齿轮25齿,三轴大齿轮36齿。从摇把到拆装轮胎钩(即图2中的上下外胎钩)轴的速比为4:1,在固定车圈的支架上有一个轴,这个轴和拆装轮胎钩轴是同心的,轴的大小和车圈轴 Our bureau succeeded in innovating a hand-held tire disassembly machine in August last year. The operation is shown in Figure 1. The machine is simple in structure, the whole machine rack is made of 10 channel welded steel, gear and shaft are made of 45 steel. The speed reduction mechanism consists of four spur gears: one shaft pinion 24 teeth, two shaft pinion 32 teeth, pinion 25 teeth, and three shaft pinion 36 teeth. From the crank handle to the disassembly and assembly of the tire hooks (ie, the upper and lower outer hooks in Fig. 2), the shaft speed ratio is 4: 1 and there is an axis on the bracket of the fixed rim. This axis is concentric with the disassembly / Shaft size and rim shaft
