滚动轴承是一种机械配件,其使用范围相当广泛,从低速架子车到高速喷气式飞机,从普通精度拖拉机到各种精密仪表,凡是具有旋转运动的机械,几乎都装有不同类型的滚动轴承。同滑动轴承相比,滚动轴承具有摩擦力小、旋转精度高、适用速度范围广、耐磨性能好和维护简便等优点。其缺点是噪声大、不耐冲击、制造复杂和成本较高。 Rolling bearing is a kind of mechanical parts, it uses a very wide range of applications, from low speed shelves to high-speed jet aircraft, from precision tractors to precision instruments, all with rotary motion of the machinery, almost all equipped with different types of rolling bearings. Compared with the plain bearing, the rolling bearing with a small friction, high precision rotation, the scope of a wide range of applications, good wear resistance and easy maintenance. The disadvantage is noise, impatience impact, manufacturing complexity and higher cost.
