求翻译：定期检查或更换零件时，需要拆卸轴承。通常轴和轴承箱几乎都要继续使用，轴承也往往要继续使用。因此，结构设计要考虑到拆卸轴承时，不至损伤轴承、轴、轴承箱及其他零件，同时还要准备适当的拆卸工具。拆卸静配合的套圈时，只能将拉力加在该套圈上，不得通过滚动体拉拔套圈。是什么意思？

Periodic inspection or replacement of parts requires disassembling bearing. Usually almost all of shaft and housing to continue to use, bearing also often have to continue to use it. Therefore, structural design to be considered when it comes to disassembling bearing, not to damage box bearings, shafts, bearings and other components, and also to prepare an appropriate removal tool. When removing static matching rings, tension can only be put on the ring, not through the rolling rings of drawing.
