In mechanical operation, hard to avoid can meet bearing fault, how to reduce the losses through simple method? Will need timely self-examination, check the working of the rolling bearing projects are sound, vibration, temperature, lubrication state etc, and the specific as follows:

First, the temperature of the bearing

Bearing temperature, usually have a bearing the outdoor temperature that out, if use oil hole can directly measured between bearing temperature, is more suitable. Usually, the temperature of the bearing with slowly starting to run up, 1-2 hours to achieve stable state. The normal temperature of the bearing capacity of the machine, heat, speed and load and different. If the lubrication, installation of appropriate, the bearing temperature sudden will rise, can appear abnormal high temperature, then must stop operation, and take the necessary measures to prevent it. Based on a lot of test data, table 4-1 listed the various mechanical bearing outer ring when the average temperature work for your reference. As temperature, speed, load by lubrication, the influence of the environment, table value only roughly said temperature range. The use of thermal can supervise the work of bearing temperature, and realize the temperature more than e. automatic alarm when households or stop to prevent burning shaft accidents.

Second, the sound of rolling bearings

The sound of the device to the working of the rolling bearing sound of the size and the sound quality inspection, bearing even if have a slight damage to peel, etc, also can send out sound and irregular abnormal sound, measured with a sound is able to identify.

Third, bearing vibration

Bearing vibration on bearing damage is very sensitive, such as peel, indentation, rust, crack, wear, etc, will be bearing vibration measurement in reflected in, so, by the use of the special bearing vibration measurement device (frequency analyzer, etc) can measure the size of the vibration, through the frequency points not that abnormal specific situation. The measurement of numerical of bearing conditions of use or sensor installation position and different, so need to every machine in advance of the measured value analysis is made after the judgment standard.

In some special use conditions, a solid lubricant grease to join in, such as join three to 5% of the no. 1 mos2 can reduce wear, improve the compressive heat-resisting ability, for high temperature, elegant, high vacuum, corrosion resistance, resistance to radiation, and extremely low temperature, and other special conditions, the solid lubricant to join engineering plastic or powder metallurgical materials, can be made with self-lubrication performance bearing parts, if use adhesive bonding solid lubricants roll in the way, and maintains a and roller forming lubrication film, to reduce the friction and wear a certain effect.
