Description

Technical Field

[0001] The utility model belongs to the field of roller equipment of a strip steel production line, and in particular relates to an auxiliary positioning device for blowing roller bearings. Background Art

[0002] Roller bearings are used to support the rolls and keep the rolls in the correct position in the frame. They are important components in the working frame of the rolling mill. During the operation of the roll bearings, fatigue spalling caused by the alternating loads on the inner and outer ring raceways and the surfaces of the rolling elements is the main failure form of the bearings. Other failure forms include wear, pitting, plastic deformation, and cracking. Therefore, regular maintenance is of great significance to extending the life of the bearings and exerting good performance.

[0003] However, in the bearing maintenance process, the bearing must be blown clean after cleaning with cleaning media. The general way to blow clean is to place the bearing upright on the ground or platform and rotate the bearing while blowing with an air gun. Since the roller bearing can reach a diameter of 980mm and weigh up to 100kg, the bearing is prone to rolling or tipping during the operation, which can easily cause personal injury on the one hand, and on the other hand, the bearing will hit the bearing rolling element after tipping, causing the bearing to be scrapped.

[0004] Therefore, the applicant urgently needs to seek technical solutions to solve the above technical problems. Utility Model Content
