轴承故障主要的识别方法

Main identification methods of bearing faults

1通过声音进行识别

1 recognize by sound

通过声音进行识别需要有丰富的经验。必须经过充分的训练才能识别轴承声音与非轴承声音。为此，应尽量由专人来进行这项工作。用听音器或听音棒贴在外壳上可清楚地听到轴承的声音。

Identification by sound requires a lot of experience. Training must be adequately trained to identify bearing and non bearing sounds. For this reason, we should try our best to do this work by hand. The sound of the bearing can be heard clearly with a listening device or a listening stick attached to the shell.

2通过工作温度进行识别

2 Identification by operating temperature

该方法属于比较识别法，仅限于在运行状态不太变化的场合。为此，必须进行温度的连续记录。出现故障时，不仅温度升高，还会出现不规则变化。

The method belongs to the method of comparative identification, and is limited to occasions where the running state is not changed. For this reason, continuous recording of temperature must be carried out. When a fault occurs, not only temperature rises, but also irregular changes occur.

3通过润滑剂的状态进行识别

3 identify by the state of the lubricant

对润滑剂采样分析，通过其污浊程度和是否混入异物或金属粉末等进行判断。该方法对不能靠近观察的轴承或大型轴承尤为有效。

The lubricant is sampled and analyzed to determine its degree of contamination and whether it is mixed with foreign matter or metal powder. The method is particularly effective for bearings or large bearings that are not close to observation.
