Example Embodiment
[0032] Example 1:
[0033] See figure 1 , figure 2 , A method for processing a super large roller, the method sequentially includes the following steps:
[0034] Processing the drum shaft: use a vertical lathe to process the bearing installation position 21 at one end of the drum shaft 2;
[0035] Installation of the drum body: The drum body 1 includes a plurality of sub-cylinder bodies 11 with equal diameters. When installing, a support ring is set inside the to-be-butted end of the sub-cylinder body 11, and then the adjacent sub-cylinder bodies 11 are sleeved on the drum The outside of shaft 2 is coaxially connected.
[0036] Welding reference block: Use a boring machine to weld the reference block 3 at the center of the side of the drum body 1. The upper and lower reference surfaces of the reference block 3 are symmetrically arranged with the center of the drum shaft 2, and the vertical reference surface of the reference block 3 is connected to the upper and lower The reference ...
