The equipment should reach the inner ring of the bearing with the pull hook of the saw, and it can not be hung on the outer ring to avoid damage caused by excessive loosening of the bearing. When using the puller, the rod should be aligned with the center hole of the bearing, there should be no skew, but also pay attention to the stress of the retractor and the bearing, and cannot be overused to damage the retractor and the bearing to prevent the retractor from slipping. The Angle of the foot should be less than 90 degrees.
Press the bearing with the press, stable and reliable work, no damage to the machine bearing. The pressure point of the press should be on the center of the bearing, and there should be no deviation. Use the thermal disassembly method to disassemble tight fit bearings... First pour the oil heated to about 100℃ on the bearing to be removed with the oil can. After the bearing ring is heated and expanded, pull the bearing out with the puller. Traction gear should be installed on the bearing to be removed, and a certain pulling force should be applied; Before heating, the shaft should be wrapped with cotton rope or thin iron plate to prevent the shaft from being heated, otherwise it will be difficult to disassemble. When disassembling the bearing from the bearing box shell hole, only the bearing box shell hole can be heated, and the bearing cannot be heated. When filling oil, the kettle should be poured smoothly on the bearing ring or roller paper machine, and a basin should be placed under it to collect hot oil to avoid waste and burns; Operators should wear asbestos gloves to prevent burns.
