我车间5t双梁桥式吊车基本上处于24小时连续运行状态。因此,大车轮的磨损速度较快。笔者通过多年的实践,总结出利用车床对其进行修复的方案。 一、踏面磨损 国标《起重机械安全规程》规定,“踏面厚度磨损达原厚度的15％时,应予报废。”如果大车轮踏面磨损不超过7％,而轮缘磨损小于原厚度的20％,则可认为踏面磨损是主要修复点,其磨损可修复,见图1。 My workshop 5t double girder bridge crane is basically in continuous operation for 24 hours. Therefore, the big wheel wear faster. Through years of practice, the author summed up the use of lathe to repair the program. First, the tread wear GB “Crane Safety Regulations” provides that “tread thickness wear up to 15% of the original thickness, it should be scrapped.” If the big wheel tread wear does not exceed 7%, while the rim wear less than the original thickness of 20 %, You can think tread wear is the main repair point, the wear and tear can be repaired, see Figure 1.
