Technical Field

[0001] The utility model relates to the technical field of bearing disassembly, and specifically, the utility model relates to a device for disassembling a coted roller bearing seat. Background Art

[0002] A bearing seat is a support for installing and fixing a bearing that can accept comprehensive loads, and it has the characteristics of being structurally compact, rotating sensitively, and being easy to maintain; wherever there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat. When overhauling and replacing the bearing, sometimes it is necessary to disassemble and separate the bearing seat from the bearing. Most of the existing disassembly methods use a puller and a hammer for manual disassembly. During the disassembly process, it is found that the labor intensity is high, the disassembly is inconvenient, and it is easy to damage the bearing seat, resulting in a high limitation in use.
