How to solve the too tight bearing of DC motor ?
1. The DC motor used by some people is too tight, which causes the bearing to heat up, causing the grease to be squeezed out. There is no lubricating oil in the bearing track, so the bearing has problems due to overheating.
2. Generally speaking, when repairing DC motors, the tolerances of the outer ring of the bearing and the end cover must be appropriate. The lower limit of the tolerance range is used, and the upper limit is unwilling to be driven. This makes the bearing chamber diameter smaller and increases the distance from the bearing. The interference amount of the circle fit.
3. If conditions permit, if you want to know more deeply, you can do an inspection test before disassembly.
