Problems solved by technology

[0002] For the supporting wheel bearing bush oil used in the rotary kiln operating under extremely severe conditions of bearing capacity and additional load, currently large rotary kilns in the cement and steel industries use heavy-duty industrial gear oil instead, which is used under extreme ambient temperature and harsh working conditions In this case, a stable oil film cannot be formed on the surface of the bearing pad, resulting in serious loss of bearing pad oil, poor bearing capacity, increased wear, frequent heating failures, and a long duration, which seriously affects the normal operation of the rotary kiln and increases the number and time of maintenance.
In this case, the support wheel bearing pad oil prepared according to the current technology is limited in use, and the protection of the bearing pad is not enough, and it is prone to napping damage.
