Reasons For High Temperature Of Bearing In Taconite Ore Crushing And Screening Machine

Bearing is the most important part of Taconite Ore Crushing And Screening Machine. When working at high temperature, we should pay attention to the temperature of bearing state and the abnormality of sound and vibration. If found abnormal, immediately stop the machine, find out the reason, confirm is not easy to break the object jam, or hammer and other parts have been damaged. The main reasons for high temperature of bearings are as follows:

1. Insufficient Lubrication

Ensuring good lubrication of bearings is an important measure to reduce production wear and improve economic efficiency. Whether the lubrication system can work properly is the premise of good lubrication of Taconite Ore Crushing And Screening Machine. When the bearing of Taconite Ore Crushing And Screening Machine is oil-cut, the friction will increase and the temperature will rise naturally. When there is too much lubricating oil injected, not only a large amount of lubricating grease will be wasted, but also the lubricating system will be disordered and the temperature will rise. When the oil hole is blocked, the phenomenon of temperature rise will also occur.

2. Improper Use Of Lubricating Grease

The choice of lubricating oil also affects the temperature rise of bearings. Too large or too small viscosity is not easy to form oil film, which can lead to excessive temperature rise of bearings. Especially when the viscosity of lubricating oil is high, it not only increases the internal friction between lubricating oil molecules, but also increases the friction between oil products and metals, thus generating too much heat.

3. Serious Wear Of Bearings

After long-term use of Taconite Ore Crushing And Screening Machine, wear and tear of wearable parts such as bearings will be serious, and then use, not only can not achieve the effect, but also will cause temperature rise, which will have a negative impact on the operation of the whole Taconite Ore Crushing And Screening Machine.

High Temperature Solution For Bearing Of Taconite Ore Crushing And Screening Machine

1. Timely Lubrication

The amount and time of lubricating grease should be changed in time according to the operation status of Taconite Ore Crushing And Screening Machine, which requires close attention to the operation status of Taconite Ore Crushing And Screening Machine. Appropriate amount of lubricating oil should be added every 400 hours. The lubricating oil added into the bearing seat should be 50% – 70% of the volume and be replaced every 3 – 6 months. Avoid the phenomenon of too much or too little lubricant injection. We should also do a good job of cleaning oil holes, to prevent the plugging of oil holes can not add lubricating oil.

2. Proper Selection Of Lubricating Grease

When choosing lubricating grease, we must choose lubricating oil with high viscosity, good adhesion and good vibration absorption characteristics; we should also take into account the economic applicability of lubricating oil and minimize the cost of investment; according to seasonal temperature changes, we should choose different lubricating oils; different lubricating greases should not be mixed; lubrication; Oil is also used to protect the surface of rolling bearings from corrosion, so it must be able to absorb condensate and so on.

3. Repair And Replace Bearings In Time

When the bearing of Taconite Ore Crushing And Screening Machine is worn out and can not be used, it must be replaced. When assembling, attention should be paid to cleaning the bearing bush, journal, oil collector and lubricating oil pipeline. Then the main bearing bush and connecting rod bush are assembled. When installing triangular belt, it should be a little looser than normal operation.
