Roller press bearing dismantling strategy

Roller press bearing dismantling strategy - 2021 01 - 28 ( A) 1) Cooking oil bearing hot disassembling method: apply to bearings and shaft for full coordination between; The oil as medium heating expansion after the bearing inner ring interference assembly, the oil temperature control at 110 ℃ or so commonly; Only limited to the bearing assembly and should not be used to remove, takes longer and pollute the environment. 2) Baking method: use the furnace or oven heating for the bearing inner ring interference assembly on the shaft after the expansion, can only be used for bearing assembly and should not be used to remove and heating time is longer than the other. 3) Auxiliary heating yoke: the method is used for right of assembly on the shaft of the removal of bearing inner ring. Work will be heated to a certain temperature when the auxiliary yoke condoms in the disassembly of bearing inner ring and clamping outside, wait until the heat transfer of auxiliary yoke for bearing inner ring and make its thermal expansion between the shaft and produce after clearance to remove; Energy waste is larger, and could lead to bearing inner ring outer surface burn. 4) 80 ℃; The applicable scope is small, economical efficiency. 5) Acetylene flame heating: bearing inner ring after the heat expansion with axial clearance to remove; Defect is uneven heating, easy to make the bearing inner ring burn even scrapped. 6) Hand knock beat: suitable for small between bearing and equipment parts, Shaft and bearing inner ring) The interference fit is; Easy to cause the parts by parts. 7) Press and top extractor: suitable for bearing inner ring between the shaft and the interference is; Small bearing extractor with a press and small volume, light weight, hand tools. Large bearing extractor is commonly with a press and hydraulic transmission. （ 2) In the presence of our site, we are generally use synthetic method, commonly used is hydraulic daughter top and knock hair more commonly used. （ 3) After demolition of bearing, need cleaning oil. Note: pay attention to screw down the time to master, don't slip wire!
