Details
1. selection of high quality bearings
1, look.
Observe the machined surface of the miniature bearing, the surface of the inferior miniature bearing is rough and the chamfer is uneven. High quality miniature bearing surface processing fine and smooth, uniform chamfer
2, turn
One hand holds the inner ring of the miniature bearing, and the other hand rotates the outer ring of the miniature bearing. The inferior miniature bearing can feel the presence of foreign matter in the miniature bearing channel when rotating, and the choice is not smooth. High-quality miniature bearings rotate smoothly and smoothly, without blocking feeling
3, listen.
Inferior bearings have "chacha" friction sound, while high-quality miniature bearings do not have the choice of miniature bearing configuration. Generally, the shaft is supported by two miniature bearings in the radial and axial directions. At this time, the miniature bearing on one side is called a fixed-side miniature bearing, which bears both radial and axial loads and plays the role of relative axial displacement between the fixed shaft and the miniature bearing box. The other side is called the free side, which only bears the radial load and can move relative to the axial direction, so as to solve the interval error of the telescopic part of the shaft and the installation bearing caused by the temperature change.
2. reasonable installation
When in use, it is necessary to keep the bearing and the surrounding environment clean and dry. A lot of fine dust is invisible to our naked eye, but as long as it enters our bearings, it will increase the wear and noise of the bearings.
Use the installation carefully. Thin-walled bearings have high precision and are not suitable for strong stamping during installation; they are not suitable for direct hammering of bearings. Otherwise, it will affect the service life of the bearing, and the more serious situation will be the direct damage of the bearing.
