The inner ring of the multi-bucket excavator bearing is tightly matched with the shaft, and the outer ring is loosely matched with the shell. The bearing can be pressed on the bearing with a pressure machine, and then the shaft and bearing of the excavator are loaded into the shell, and the end face is padded with soft metal material. Assembly casing (copper or soft steel pipe). The inner diameter of the assembly sleeve should be slightly larger than the diameter of the journal, and the outer diameter should be smaller than the rib diameter of the inner diameter of the excavator bearing to avoid pressing on the cage. A handle can be added to the housing for large-scale installation. During installation, the hole coincides with the centerline of the shaft. The skew of the excavator bearing relative to the shaft is not only difficult to install, but also causes indentation, journal bending, and even the inner ring. Break.

The installation and disassembly method of the multi-bucket excavator bearing should be determined according to the structure, size and nature of the components. The pressure of installation and disassembly should be directly applied to the end face of the tightly matched retaining ring. The pressure cannot be transmitted through the bearing rolling body of the multi-bucket excavator, because this will cause indentation on the working surface, affect normal work, or even damage. The retaining ring, sealing ring, dust cover and other parts of the excavator bearing are easily deformed, and the pressure of installation or disassembly cannot be applied to these parts.

Where there is a lack of a press or cannot be used, the bearings of the multi-bucket excavator can be installed with a matching device and a small hammer. The hammering force should be evenly transmitted to the entire circumference of the end face of the excavator bearing ring, so the hammering end face of the assembled casing should be made into a spherical shape.

The outer ring of the multi-bucket excavator bearing is tightly matched with the bearing seat hole, and the inner ring is loosely matched with the shaft. It can be pressed into the shell first. At this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the shell hole.
