Hunan Jintai Hardware and Machinery Co.,Ltd. At the time of dismantling, according to the drawings, the method and order of dismantling are discussed, and the conditions for cooperation of self-lubricating bearings are inquired in order to obtain full assurance of the dismantling work.
1, open the outer ring
To open the outer ring of interference and cooperation, set several outer kneading screw screws on the circumference of the housing beforehand, and tighten the screws equally while one side is open. These screw holes are usually covered with blind plugs, self-lubricating bearings, such as self-lubricating bearings with tapered rollers and self-lubricating bearings, are cut at several positions on the shoulder of the housing, and the pads are used to separate them with a press, or they are opened and unfastened.
2. Disassembly of cylindrical hole self-lubricating bearings
The dismantling of the inner ring enables the mechanical extraction of the latest briefs. At this point, pay attention to allow the inner ring to receive its pulling force. The self-lubricating bearing with a large width is used together with a drawing fixture in the oil pressure method to perform disassembly work. The induction heating method can be used to disassemble the inner rings of NU and NJ cylindrical roller self-lubricating bearings. Heat the part for a short period of time so that the inner ring expands and then pulls.
3, split hole self-lubricating bearings open
Remove the comparatively small self-lubricating bearing with an adapter sleeve, support the inner ring with a block that is fastened on the shaft, turn the nut back several times, and use the block to open it with a boring head.
