Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] Such as Figure 1 to Figure 5 As shown, a method for reducing the clearance of the roll thrust bearing is characterized in that it includes:
[0024] According to the movement requirement of the roll 2, disassemble the bearing housing 1 that does not meet the movement requirement to take out the thrust bearing 3, take out the two rows of inner rings 22 and spacer rings 23 of the thrust bearing 3 from the outer ring 21, record the interval the width of circle 23 and denoted as A;
[0025] Put the two rows of inner rings 22 back into the outer ring 21, record the gap between the two rows of inner rings 22 and mark it as B;
[0026] According to the instruction manual of the thrust bearing 3, determine the required clearance range of the thrust bearing 3 and denote it as C;
[0027] Grind the spacer ring 23 from width A to width B+C, and put th...
