Release time:2014-08-07 09:12:19 Source of the article:qyjljc Number of clicks:1847

  When the coiling machine is in operation, the bearing and other parts will rise rapidly due to the operating temperature of the equipment, and the equipment operation is allowed to have a certain temperature change. This is a normal phenomenon, but it is also necessary to be alert to the case that the bearing temperature is too high. The main reasons for the excessive temperature of the coiler bearing are as follows:

  1. It may be that the load of the rolling machine bearing is too large or the assembly is too tight.

  Second, the viscosity of the lubricating oil is too high or the quality does not meet the requirements.

  Third, the assembly of the coiling machine is insufficient, the bearing cage and the rolling element rupture will also cause the bearing temperature to be too high.
