Regarding the issue of lubricating bearings with grease
Thread Content
The book says that there is a certain amount of lubricant required. For the motor of our pump, which is an ordinary motor, no need was observed to control the amount of lubricant used. What exactly does the term \"free space\" and \"internal space\" refer to as mentioned in the book?
What exactly does \"re-lubrication to the end\" mean?
Generally, it is added up to one-third of the bearing clearance; the remaining two-thirds of the clearance is used for heat dissipation, ensuring that the heat generated during bearing operation can be dissipated promptly, thereby preventing temperature buildup that could lead to overheating and damage to the bearings.
What do bearing clearances and the other clearances refer to?
Between the inner and outer races of the bearing, aside from the springs and retainers, there is only a gap.
On one hand, the amount of grease must be sufficient to ensure proper cooling of the bearings; on the other hand, if too much grease is used, there is no space for heat dissipation, which can lead to overheating
I’ve learned it.* Anyway, heat is always hot, so one would need grease that can withstand high temperatures
Equipment that requires fat addition is generally sealed and not visible; the amount of fat to be added can only be determined based on the specifications provided by the manufacturer.
Not necessarily; for ours, it’s the fitter who installs the motor, by simply shooting it in with a gun
Yes, it’s just a matter of the amount of fuel added. Generally, adding too much fuel to a two-pole motor doesn’t cause any problems, but with four-pole motors, excessive fuel can lead to overheating; it’s best to gain experience through trial and error!
