For grease lub of electric motors, virtually all the bearing manufacturers and motor manufacturers give instructions to pack the beairng housing some fraction full of grease (somewhere between 1/2 and 3/4 full.. toward the lower end for fast speed large bearings).
That seems to leave some room for interpretation. Let's say it's a horizontal machine. Would you:
A - Set the endbell on it's back and pack the cavity 1/2 deep. Then when endbell is assembled to bearing, grease is at the opposite end of the cavity from bearing.
B - Set the endbell on it's side and back the bottom half (3:00 to 6:00). Then upon assembly the grease will be in contact with lower half of the bearing.
C - Put small chunks of grease into the bearing trying to trap air between chunks so when the cavity is full you have only about 50% grease by volume and 50% air by volume, and grease will be adjacent to the beairng all the way around.
D - Something else?
(of course grease will be applied directly to bearing as well).
Are there any references that describe WHERE the grease should be packed in the bearing?
