Issues related to the gear mesh clearance in centrifuges.
Thread Content
I just saw a post saying that after maintenance, the centrifuge needs to be reinstalled, and it’s necessary to check the gear mesh clearance; there are methods such as the lead compression method and the dial indicator measurement method. Since I’ve never dealt with this before, I would like to ask: if it’s detected that the meshing clearance does not meet the standards, how can this clearance be adjusted? Aren’t the bearing position and the shaft position fixed?
Do you mean measuring the side clearance and end clearance of the gear?
There are tilting pad bearings inside the bearing housing; I don’t see any place where it can be adjusted
Pasted from the internet: After installing the gear pair: 1. Measure the side clearance using a feeler gauge. 2. Fix one gear, place a dial indicator on the tooth profile of the other gear, and rotate that gear back and forth; the change in the reading of the dial indicator represents the side clearance. In some cases, the \"compression method\" using fuses can be considered to measure the meshing clearance. Cut a small piece of fuse, apply a little lubricant, and stick it on the side of the tooth. Turn past this tooth, remove the rolled fuse, and measure its thickness. For reference
It is not adjustable, but if the tilted tiles are worn out and replaced, there will be an improvement. In the past, thick-walled tiles could be adjusted by scraping to create a gap.
