Hello,
My question is about bearings. I understand that we should not lubricate axleboxes from the top, as that is the centre of pressure, and they should be fed from the side or below. All OK.
However, in the case of stationary engines, or others where there is no standing weight from above, and depending on the direction of drive from the crankshaft, surely it is OK to lubricate from above, as the centre of pressure does not lie there. In reciprocating engines, thrust is applied at more or less 90 degrees plus or minus from the vertical, and with no standing weight, it should be OK to lubricate from above.
In doing so, it enables a small recess to be formed in the bearing, in which an oiler can be inserted, or a pool of oil laid, so as to feed to machine during its running. This will facilitate a short period of operation, such as my power hacksaw, or demonstration run, without complex oiling problems.
Am I right? Or, in which case, am I wrong?
Regards
Geoff
