货车滚动轴承热轴故障分析及解决措施毕业设计（论文） reakdowns are becoming more prominent, especially in a large rolling bearing failure amplitude increased, the use of departments do a good job rolling bearing anti-burn, anti-cutting work to become an important research topic. Rolling in an enclosed structure, and how to check in daily to find faults in a timely and accurate, and effectively prevent the rolling bearing failure, ensure road safety and smooth flow of this issue is before us. Railway freight railway transport of goods vehicles, wheel, roller bearing railway truck Bogies most important and is interchangeable parts, its technical condition directly affects the safe operation of vehicles. After the railway in recent years, a large-scale transformation of the truck, truck rolling bearing technology has been basically achieved, bearing failure has become a smooth and safe rail transport impact of the key factors of production. Accurate analysis and assessment team in place dealing with the train bearing failure, reduce the half-way stop rejection car, to prevent burning, cutting shaft accident is listed as an important duty of
