Hi,
Quick question;
On an old rotor assembly drawing we received, there's a table with general tolerances ('unless otherwise specified'). Now in this tolerance table there are 3 columns: Machining, fabricating, casting.
I only know certain ISO-norms, such as ISO 2678-mK. I'm unfamiliar with...
Hi,
I'm unable to find a standard concerning rounded keys.
As seen by the image, the top part of the key is also rounded. Meaning the keyway in the hub has a rounded contour instead of a rectangular contour.
I'm reverse engineering a shaft with impellers that have these rounded keyways...
Hello,
Does anyone know if there's a metric standard for a shaft that has 2 keyways, spaced 180 degrees apart, but both in the same axial place on the shaft. I'm looking for general tolerances and stuff (if there's any).
Thank you.
Hi everyone,
We're engineering a compressor for a chemical plant. The compressor has a rectangular exhaust pipe, which by a conical nozzle turns into a 20" piping system.
The rectangular exhaust has a width of 410mm x 260mm height. The idea is to create a spool piece at the rectangular exhaust...
Hi,
Trying to figure out how much thread will deform during shrink fit. We're reverse engineering shaft sleeves for a compressor rotor and 2 of the sleeves have thread on them.
Bore diam. is around ∅110mm - thread is 4 1/2" - 12 UN (external)
Will the thread be viable if we were to design it...
