孔、轴类零件过盈配合安装是设备维修、装配过程中经常遇到的课题,由于生产现场通常不具备压力机、低温等现代化的装配工艺技术措施的条件,而利用热膨胀法进行孔、轴类零件装配是现场施工最常用的技术手段。对孔、轴类零件过盈装配过程中如何根据过盈量计算加热温度,零件加热过程的控制,防止被加热金属过热,给出方法与采取的必要措施。
Hole, shaft interference fit with the installation of equipment maintenance, assembly process often encountered problems, due to the production site usually do not have the press, low temperature and other modern assembly technology and technical conditions, and the use of thermal expansion of the hole and shaft Assembly of parts is the most commonly used technical means of construction site. How to calculate the heating temperature and the heating process of the parts according to the interference during the interference assembly process of the holes and shaft parts to prevent overheating of the heated metal and give the methods and necessary measures to be taken.
