在机床及各种机械设备中,常用弹性挡圈来固定轴上的零件,如轴承、齿轮等。这种固定方式具有结构紧凑,定位可靠等特点。但是,在设备维修过程中,弹性挡圈的拆卸却很困难。我们知道,弹性挡圈是用卡钳将其胀开后装拆的,由于弹性挡圈的厚度很薄,而且弹性挡圈往往紧贴着被固定零件,因此卡钳用力时很容易从挡圈中滑出,特别是在窄小的空间,工人拆卸一个挡圈往往要花费很多时间和精力。针对这一 In the machine and various machinery and equipment, commonly used elastic ring to fix the shaft parts, such as bearings, gears and so on. This fixed way with a compact, reliable positioning and so on. However, it is difficult to disassemble the circlips during equipment maintenance. As we know, the circlip is assembled and disassembled after it is expanded by a caliper. Since the thickness of the circlip is very thin and the circlip tends to be close to the fixed part, it is easy to slide the retaining ring from the retaining ring Out, especially in narrow spaces, workers often spend a lot of time and effort disassembling a retaining ring. For this one
