Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a special tool for centering vertical grinding spherical bearings. Background Art

[0002] The vertical mill bearings in cement plants are basically cylindrical double-row tapered bearings and spherical bearings. Among them, the spherical bearings installed in the equipment need to be disassembled and inspected for wear and fatigue after a period of use. Since the vertical mill is placed flat, the spherical bearing is also parallel to the vertical mill. The inner ring needs to be rotated to align the center. Even if the inner and outer rings are misaligned, it is possible to detect whether the bearing is fatigued or damaged, and other unqualified quality phenomena.

[0003] However, the spherical bearings installed on the equipment are large in size and heavy in weight, and rotating the inner ring is difficult. There is also a lack of dedicated tooling, which results in low efficiency in bearing inspection. Utility Model Content
