Symptoms usually manifested as two rolling bearings, one bearing installation site temperature is too high, the second is bearing noise operation.
Symptoms usually manifested as two rolling bearings, one bearing installation site temperature is too high, the second is bearing noise operation.
1. The bearing temperature is too high
When agencies operate, install the bearing parts to allow a certain temperature, when the stroking mechanism housing should not feel hot to normal, otherwise it indicates the bearing temperature is too high.
High bearing temperatures reasons: oil quality does not meet the requirements or deterioration, oil viscosity is too high; tight body assembly (lack of space); bearing assembly too tight; bearing race rotating shaft or housing; overload big; rolling element bearing cage or fragmentation.
2. bearing noise
Rolling allow a slight noise at work, if the noise is too large or unusual noise or crash, then the bearing is faulty.
Rolling noise is more complex reasons, one is the bearing inner and outer rings with surface wear. Due to this wear, damage to mating relationship with the housing bearing, the bearing and the shaft, resulting in an axis deviation from the correct position, the shaft abnormal sound generated when high-speed movement. When the bearing fatigue, its surface metal flake, but also make the bearing radial clearance increases produce abnormal sound. In addition, lack of bearing lubrication, the formation of dry friction, and bearing broken, etc. will have an unusual sound. Songkuang after bearing wear, loose cage damage, will produce abnormal sound.
