hub bearing 汽车轮毂轴承

轮毂轴承(hub bearing)的主要作用是承重和为轮毂的转动提供精确引导,它既承受轴向载荷又承受径向载荷,是一个非常重要的零部件。传统的汽车车轮用轴承是由两套圆锥滚子轴承或球轴承组合而成的,轴承的安装、涂油、密封以及游隙的调整都是在汽车生产线上进行的。这种结构使得其在汽车生产厂装配困难、成本高、可靠性差,而且汽车在维修点维护时,还需要对轴承进行清洗、涂油和调整。轮毂轴承单元是在标准角接触球轴承和圆锥滚子轴承的基础上发展起来的,它将两套轴承做为一体,具有组装性能好、可省略游隙调整、重量轻、结构紧凑、载荷容量大、为密封轴承可事先装入润滑脂、省略外部轮毂密封及免于维修等优点,已广泛用于轿车中,在载重汽车中也有逐步扩大应用的趋势。

Wheel hub bearing is the main function of bearing and provide accurate guide to the rotation of the wheels, it was under axial load and bear radial load, is a very important component. Traditional car wheel with bearing is combined by two sets of tapered roller bearings or ball bearings, and the installation of the bearing, oil seal and clearance adjustment is carried out on the auto production line. This structure makes it in the car factory assembly difficulty, high cost and poor reliability, and when the car in pits maintenance, also need to clean, oil bearing and adjustment. Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, developed on the basis of it will be two sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, ?
