Wear Life of Thrust Bearing in FTM Impact Crusher

To impact crusher, thrust bearing is a key part and composed of three disks. Since thrust bearing often works in extreme conditions, it is more or less worn out during every work of impactor crusher. Then, what are the wear life of thrust bearing? The following content will give you answers.

Parameters of upper disk and middle disk like relative sliding speed, oil film defect and wear coefficient are all constants. Firstly, we get the average value of contacting stress at every analyzing point. Then, we take the value into service life formula of adhesive wear, and count the average wear life of upper disk as 1,515h.

Lower thrust disk is fixed. Relative sliding speed at contacting points between middle disk and lower disk is just the absolute speed of middle disk. According to the movement rules, we can get that absolute speed of middle disk changes along with the periodic change of times. Through the deviation of formulas, we can get that contacting stress decreases along with the radius increase.

To count the average wear extent of lower disk, we need to select 7 analyzing points. After counting the wear extent at every point, we get the average wear extent. Based on that, we can deduce that the wear life of lower disk is 2,247h. The above analysis and results on thrust bearing are basically anastomotic with the changing period of thrust bearing in enterprises.

Therefore, it is seen that this method is available. This method is and will be the theoretical reference for changing period of thrust bearing in impactor crusher. See price list on website!
