Problems solved by technology

[0003] However, as the thrust bearing is used longer and longer, the rolling body of the thrust bearing and the outer ring of the bearing wear more and more, resulting in a larger clearance of the thrust bearing. The effect is getting smaller and smaller, which makes the movement of the roll in the bearing seat more and more large, causing the roll system of the rolling mill to be unstable, directly affecting the shape of the steel plate, and in severe cases, causing damage to the steel plate scraping frame and equipment, affecting production continuity and The production cost has a great influence, so it is necessary to study a method to ensure that the roll thrust bearing clearance meets the design range

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...

Abstract

The invention relates to the technical field of bearing clearance adjustment, in particular to a method for reducing the clearance of a roller thrust bearing. The method is technically characterized by comprising the following steps that a bearing block is disassembled to take out the thrust bearing, two inner rings and a spacer ring of the thrust bearing are taken out, the two inner rings are assembled into an outer ring, the clearance range of the thrust bearing is determined, the spacer ring is grinded, and finally the spacer ring is assembled into the thrust bearing. The method has the advantages of improving the use performance of the thrust bearing and ensuring the stability of a roller roll system.

Description

technical field [0001] The invention relates to the technical field of bearing clearance adjustment, more specifically, it relates to a method for reducing the clearance of a roll thrust bearing. Background technique [0002] In the hot-rolled plate production line, due to the assembly precision of the rolls, the intersection of the roll system and the precision of the roll grinding, etc., the axial movement of the rolls occurs during the rolling process of the steel plate. The generated axial force is borne by the roll thrust bearing, that is, the role of the roll thrust bearing is to ensure that the axial movement of the roll in the bearing seat meets the requirements. [0003] However, as the thrust bearing is used longer and longer, the rolling body of the thrust bearing and the outer ring of the bearing wear more and more, resulting in a larger clearance of the thrust bearing. The effect is getting smaller and smaller, which makes the movement of the roll in the bearin...
