高精密轴承套杯式缓冲垫性能试验研究

Experimental Study on the Performance of High Precision Bearing Cup Cushion

针对高精密轴承的缓冲包装问题,采用HL-1029有机硅胶制作高精密轴承套杯式缓冲衬垫。先制得HL-1029有机硅胶材料试件,并对其进行单轴拉伸试验;对试验结果进行分析和计算,得出HL-1029有机硅胶作为高精密轴承的缓冲包装衬垫的厚度至少为12 mm。再对以12 mm和17 mm厚有机硅胶缓冲衬垫包装的高精密轴承,进行跌落仿真试验,得到跌落时轴承受到的应力、应变云图。由试验结果可知,HL-1029有机硅胶缓冲衬垫能有效地保护高精密轴承。

In order to solve the problem of cushion packaging of high precision bearing,HL-1029 organic silica gel was used to make the cup cushion of the high precision bearing.First,the HL-1029 organic silica gel material test piece was made,and its uniaxial tensile test was carried out.The test results were analyzed and calculated,and it was found that the least thickness of HL-1029 organic silica gel used as cushion packing liner of the high precision bearing should be 12 mm.Then,the drop simulation test was carried out with the high-precision bearing packed with 12 mm and 17 mm thick organic silica gel cushion,and the stress and strain nephogram of the shaft during the drop was obtained.According to the test results,the HL-1029 organic silica gel cushion could effectively protect the high-precision bearing.
