Im sorry for the simple question, but I am having a small difficulty with this problem I am having.
Basically, I need to tap a blind 5/8-8 hole into an aluminum piece I have made.
Almost all of the taps I have found are tandem, so I cannot use them. There are also roughing and finishing sets...
I currently have a welded structure made of various wall thickness 4130 square tubing. The tubing is all 1x1 inch with wall thicknesses ranging from .035 to .125 inches.
The tubes have varying lengths between 4 to 18 inches and are interconnected.
I do not know exactly how the welds were...
If you were to make a hollow shaft with the following dimensions, how would you do it?
OD - 65.000mm/64.95mm
ID - 56mm/54mm
Length ~ 500mm
There will be no bearings directly run on said shafts. The shafts will be under approximately 50-60 MPa of stress and will be rotating at 2000 RPM.
I...
Hello All,
Right now I am designing a steel structure out of 4130 steel. I have designed in some bearing holders to be welded in, but have had a difficult time finding a supplier for the material.
The bearing holder is a flanged design with an OD of 6 inches and bearing surface of 4.156...
Any advise on how to attach a pulley to a hollow shaft?
Background info:
Shaft Material: Steel (exact type not determined)
Pulley Type: Synchronous Belt (14M 6.32" Pitch Diameter, 2000 RPM, 125HP, 315 ft-lbs TQ)
Shaft OD: 50mm
Shaft ID: 40mm
My initial thought is taper lock bushings (2517...
How difficult is it to machine a shaft with internal steps?
Some info about proposed shaft:
OD: 70mm
ID (starting from bottom): 54mm, 58mm, 62mm
Length: ~1m
Material: 440C (HRC 60 necessary)
The steps all increase in diameter, so it could theoretically be bored. The internal dimensions...
