There are pictures. . The drum compressor measures the back interference of the support bearing, and finally multiplies it by 1.1. Where does this coefficient come from?

Our company recently installed a compressor. The support bearing is a tilting pad bearing with two upper and three lower parts. When measuring the interference of the pad back, the measured data must be multiplied by 1.1 to get the result. But I really can't figure out how the coefficient of 1.1 is calculated? I hope someone can help clear up the confusion. . Thanks in advance!
Judging from the picture, what you should want to ask is the gap measurement problem. Interference does not need to be multiplied by a coefficient. There are errors when measuring gaps. Especially if you are using a lead wire to measure the gap between tilting tiles, because with five tilting tiles, you are pressing the gap between the lower tile and the upper side tile, not the radial gap in the vertical direction. You need to use a coefficient to compensate. If it is an ordinary round tile or oval tile, the top gap is directly pressed.
Thanks for the reply. The last picture was uploaded incorrectly and can be ignored. What I want to ask is why do you need to multiply by 1.1 when measuring the interference? How is this 1.1 calculated?

The API requires that the interference is generally 0-0.03mm. The interference of the sinking drum is usually 0-0.02mm. Many foreigners have clearance because the bearing expands after being heated. This parameter does not need to be multiplied by the coefficient. The 1.1 you mentioned is the compensation coefficient when the tilting pad presses the lead wire.
One word to reveal the person in your dream! Thx..
In fact, the interference amount of 0.00-0.02MM is very measurable, and even when measured, it is very accurate. Do you have any good interference measurement methods? Please ask for help.
