I have another question regarding bearings
Thread Content
I’m not very familiar with bearings. I would like to ask the experts: in the case of ball bearings, is the inner ring tightly fitted around the shaft, and is bearing clearance the space that allows movement between the inner and outer rings? Thank you.
The inner ring and the shaft have a transitional fit; I’ve seen that motor bearings are installed under heat, and if they’re too loose, it’s easy for the inner ring to move
The inner ring is tightly fitted around the shaft. As for the bearing clearance you mentioned, it’s very small; I’m not sure what that means
The most basic structure of a rolling bearing consists of an inner ring, an outer ring, rolling elements, and a cage. The functions of various components in bearings are as follows: the inner ring is usually in a tight fit with the shaft and rotates together with it, while the outer ring is typically in a loose fit with the bearing housing or the hole in the mechanical frame, serving a supporting role. For rolling bearings, under normal assembly, an interference fit is generally used. Common methods for assembling interference fits include: the temperature difference method, the pressing method, etc. The clearance of a rolling bearing refers to the maximum amount of movement of one ring while the other ring remains fixed, either radially or axially. The maximum movement in the radial direction is called radial clearance, while the maximum movement in the axial direction is called axial clearance. Generally speaking, the greater the radial clearance, the greater the axial clearance, and vice versa. Generally, rolling bearings cannot have their clearance adjusted, let alone be disassembled
