机床轴承台架考核报告
收藏资源简介:
本文件针对高速高精密轴承性能测试和评价的需求,通过精密轴承台架测试,在短时间内模拟精密轴承损伤特征,形成此报告结果。用以支撑精密轴承性能评价。现阶段针对精密机床轴承的台架测试,主要有两种方式。一种是采用经典的行业内测试方法,通过增大轴承负载进行加速实验,在1/3额定转速试验转速 10000 r/min、1/3额定载荷,当量载荷2.749 kN径向载荷2.51KN (X=0.435 )轴向载荷1.6KN(Y=1),试验润滑L-HM 32油润滑的条件下,进行轴承台架试验,所用实验设备为杭州轴研科技生产的轴承试验机。加速台架考核实验证明机床主轴轴承P2级精度保持性达2000h以上。符合预期考核指标。
This document targets the requirements for performance testing and evaluation of high-speed and high-precision bearings. Through precision bearing bench tests, damage characteristics of precision bearings are simulated within a short time frame, and this report outcome is generated to support the performance evaluation of precision bearings. Currently, there are two main approaches for bench testing of precision machine tool bearings. One is the classic industry-standard test method, which uses increased bearing load to conduct accelerated experiments. The bench bearing test is carried out under the following conditions: 1/3 of the rated speed with a test speed of 10000 r/min, 1/3 of the rated load, equivalent load of 2.749 kN, radial load of 2.51 kN (X=0.435), axial load of 1.6 kN (Y=1), and lubrication with L-HM 32 oil. The experimental equipment used is a bearing testing machine produced by Hangzhou Zhouyan Technology Co., Ltd. The accelerated bench qualification test has verified that P2-grade precision machine tool spindle bearings can maintain their accuracy for more than 2000 hours, which meets the expected assessment indicators.
