The axis of agricultural ball bearings is its central axis, and the diameter is its diameter. Then the axial direction is the direction of the central axis, and the radial direction is the diameter direction.
The axial direction is usually for cylindrical objects, which is the direction of the central axis of rotation of the cylindrical body, that is, the direction common to the central axis.
The radial direction is perpendicular to the axial direction, that is, the radius or diameter direction of the cylinder end face circle, and the radial direction is perpendicular to the axial space.
Popularization of knowledge on disassembly methods for daily maintenance of agricultural ball bearings
The disassembly of agricultural ball bearings is for regular maintenance, and it is carried out when the bearings are replaced. After disassembly, if you continue to use it, or you need to check the state of the bearing, the disassembly should be carried out as carefully as the installation. Be careful not to damage the various parts of the bearing, especially the disassembly of the interference fit bearing, which is difficult to operate.
It is also important to design and manufacture disassembly tools as needed. When disassembling, study the disassembly method and sequence according to the drawings, and investigate the matching conditions of the bearing, to obtain a foolproof disassembly operation.
Removal of the outer ring For the outer ring with interference fit set several screws for the outer ring extrusion screw on the circumference of the outer casing in advance, and tighten the screw evenly while disassembling. These screw holes are usually covered with blind plugs, separable bearings such as tapered roller bearings, etc., and several notches are set on the shoulder of the housing. Use spacers to remove with a press, or lightly tap to remove.
The disassembly of the inner ring, which can be pulled out with a press is the easiest. At this time, pay attention to letting the inner ring bear its pulling force. Furthermore, the pull-out clamps shown are mostly used, and no matter which kind of clamps, they must be firmly clamped on the side of the inner ring. For this reason, it is necessary to consider the size of the shaft shoulder, or study the machining of the upper groove at the shoulder, to use the drawing jig.
The disassembly of the inner ring of the large bearing adopts the hydraulic method. Oil pressure is applied through the oil hole provided in the bearing to make it easy to pull out. For bearings with large widths, the hydraulic method is used in combination with the pulling jig for disassembly.
