Need help identifying parts of a pulley

[Twoply 0]

I'm fabricating a little something and I need a very specific pulley.

Problem is my vocabulary is lacking.

I need this portion of the shaft to be exactly 2 3/8".

What is this portion of the pulley referred to as?

Axle?

Shit happens. And it usually happens because of physics.

Hub

I'm gonna go with "Hub", maybe "integral hub", since it seems to be cast as one piece along with the wheel.

ARE you building a concrete rebound hammer?

I'm going to guess Bushing for the axle. The 2 female screw inserts look like that is fastened to something else. The axle appears to be inserted into that. OR the inserts are for set screws to fix the pulley (channel wheel?) axle to the large hub in which case the hub would be an enlarged extension of the axle.

This probably makes no sense whatsoever but it's not the first time I've done this.

Since that pulley will be rotating with the shaft it is likely that the shaft and pulley share a key way. Do a search for "keyed shaft and pulley" in the image area.

pully axle or shaft.

integral hub

It is not a bushing, as a bushing is internal and is a bearing surface. A bushing is typically installed to reduce the diameter of the hole a shaft goes into. It is not an axle, as an axle is the shaft that a wheel or pully turns around. It is not a shaft. It is a device that slips over a shaft.

I think that part of the drawing is best described as a sleeve with threaded set screw holes. (As a sleeve "slips over somethng".)

Hub.
And try "sheave" instead of "pulley".

Alcohol never really solved any problems. But then again, neither did milk.

Ding ding ding! We have a winner.
It is a sheave with a hub (integral hub).
