技术领域technical field

本实用新型涉及轴承拆卸技术领域,具体是一种滚动轴承外圈拆卸装置。The utility model relates to the technical field of bearing disassembly, in particular to a rolling bearing outer ring disassembly device.

背景技术Background technique

滚动轴承是将运转的轴与轴座之间的滑动摩擦变为滚动摩擦,从而减少摩擦损失的一种精密的机械元件,滚动轴承一般由内圈、外圈、滚动体和保持架四部分组成,内圈的作用是与轴相配合并与轴一起旋转;外圈作用是与轴承座相配合,起支撑作用;滚动体是借助于保持架均匀的将滚动体分布在内圈和外圈之间,其形状大小和数量直接影响着滚动轴承的使用性能和寿命;保持架能使滚动体均匀分布,引导滚动体旋转,起润滑作用,在轴承的使用过程中,由于转动会产生磨损,时间久了会导致轴承的损坏,在一些三轮车等车轮部位的轴承出现问题之后,车轮的行走会出现异响,影响车轮转动时的流畅性和稳定性,因此需要对坏掉的轴承进行更换,但是,在更换时,轴承的外圈卡在轴承座中不易取出,现有的方式大多通过电焊的方式取出,但是采用电焊方式取出容易使得油口处出现损坏,造成日后漏油的情况,另外,也有一些人采用敲击的方式取出,但是敲击方式会使得外界车辆上的轴承座以及损坏的轴承外圈受力不均匀,容易造成轴承座的变形以及损坏。Rolling bearing is a precise mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling body and cage. The function of the ring is to cooperate with the shaft and rotate with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage. The shape, size and quantity directly affect the performance and life of the rolling bearing; the cage can make the rolling elements evenly distributed, guide the rolling elements to rotate, and play a lubricating role. The bearing is damaged. After the bearing of some tricycles and other wheel parts has problems, there will be abnormal noise in the walking of the wheel, which affects the smoothness and stability of the wheel rotation. Therefore, the broken bearing needs to be replaced. However, when replacing , the outer ring of the bearing is stuck in the bearing seat and it is not easy to take it out. Most of the existing methods are taken out by electric welding, but the use of electric welding can easily cause damage to the oil port, resulting in oil leakage in the future. In addition, some people use Take it out by knocking, but the knocking method will make the bearing seat on the outside vehicle and the damaged bearing outer ring unevenly stressed, which is easy to cause deformation and damage of the bearing seat.

The bottom end of the connecting rod is provided with a fixing hole for fixing, and at the same time The outer ring of the bearing is fitted with screw holes, and the inner ring is fitted with screw holes. When disassembling, fix the disassembly device on the outer or inner ring to be disassembled, press the screw against the end face of the shaft, and rotate the screw. The disassembly is complete.

但是上述方式主要针对特殊的具有螺孔以及螺纹孔的轴承进行,大部分轴承并没有相应配合的孔实现与上述拆卸工具的对接,另外,上述方式主要针对轴承套设在轴上的情况时的拆卸,但是有时轴承损坏时,轴承的内圈与外圈已经分离,而外圈卡在轴承座中无法拆卸,上述方案无法针对此种情况进行操作,使用受限。However, the above methods are mainly used for special bearings with screw holes and threaded holes. Most of the bearings do not have corresponding matching holes to realize the docking with the above-mentioned disassembly tools. In addition, the above methods are mainly used when the bearing is sleeved on the shaft. Disassembly, but sometimes when the bearing is damaged, the inner ring and outer ring of the bearing have been separated, and the outer ring is stuck in the bearing seat and cannot be disassembled. The above solution cannot be operated for this situation, and its use is limited.
