The sealing performance of the transmission gear section is poor.The transmission gear size of barite ore grinding plant is generally large.
According to the relevant national design standards, there is a certain numerical error on the gear surface. Therefore, a sealing device is required to ensure the sealing performance between barite ore grinding plant gears.
However, in the existing processing technology, many barite ore grinding plant gear sections are processed by the end face pressurization method. The gears produced by this process have good early use effect and good sealing performance.
However, after running for a period of time, the felt on the end face is extruded, which will lead to the loss of elasticity of the felt, Thus, the sealing performance of the gear fails. The failed sealing device will allow more dust and impurities to enter the gear.
