OT: Bearing type for horizontal mount of sprocket |
|
|
I have something in mind that I need for a project, but I don't know what
it's called, so I can't find it. I'm hoping that one of you can help.
This project will have two sprockets (one that drives a chain, one that
guides it) mounted horizontally (think the Wheel of Fortune wheel as opposed
to the Price is Right wheel). One sprocket will be attached to a motor; the
other will need to be on a bearing. I'm thinking of a pillow-block type of
bearing, but with a vertical shaft that I can drop the sprocket down onto.
Preferrably the bearing 'block' will have a few mounting holes so it can
mount to a horizontal board.
Did that make sense? If it did, is there a name for such a bearing so that
I may find one that'll work for me? Websites would help as well.
Bonus points--find a website that shows me how to design a sprocket in
SolidWorks. I found this one:
http://www.gizmology.net/sprockets.htm
.... but either I'm doing something wrong or the instructions are
unclear/incorrect (I'm not getting the results that I should).
Thanks in advance for your help!!!

Hey Brian,
What you're describing is called a Flange-Mount Ball bearing.
Look it up at McMaster-Carr, and you'll find more than you can shake a stick
at.

Sorry, I didn't read to the Bonus Points section.
I think that the description is very good, and should result in a fairly
good sproket for a SW model.
If you need help email me your sproket specs, and I'll see what I can do.
BTW, Thanks for the link, I ordered the Chain book (it's FREE).

Re: Bearing type for horizontal mount of sprocket |

I managed to figure it out & draw a sprocket that's adjustable by number of
teeth. I still think there's something wrong with the steps given at that
website. In the second illustration they tell you to offset the lines drawn
in the previous step by the chain pitch. It appears that they offset the
middle (vertical) line by pitch on BOTH sides--so when you draw circles at
the intersections (in the next step), they are apart by 2X pitch. See what
I mean?
I went back to McMaster-Carr (had been there before but didn't see what I
was looking for) and with your help I was able to find exactly what I need.
Thanks!

Glad I could help.
Yes, I do see what you mean. I guess it could have been worded better, but I
'm glad that you got what you're looking for.

Hi,
A couple of thnigs: try www.camnetics.com for GearTrax - it
will make sprockets "automatically" given the correct parameters. I
use this software often and really like it. You can get a free 10 day
trial. This will make short work of the sprocket. Second, have you
looked around McMaster-Carr for the "bearing block"
(www.mcmaster.com)?
Sounds like a clothing conveyor system. Those work fundamentally like
you describe.

Keep in mind that many mounted bearings use bearing cartridges with a
spherical OD which accommodates a measure of axial misalignment between two
installed bearings. One such bearing cannot be used to support a
cantilevered shaft otherwise the bearing will swivel in the housing when a
light load is applied. Two mounted bearings must be used with a degree of
separation between them proportional to the applied loads and bearing
capacity.

Brian,
We use Brewer Machine products as well as Martin and Browning. They all
have sprockets with bearings mounted and a selection of mounting posts with
brackets. Try brewertensioner.com.

Re: Bearing type for horizontal mount of sprocket |

If you still are looking for sprocket help, I have a sprocket part that is
built on a design table that will build any size RC sprocket. You copy a
line from the proper size (RC60, RC80 etc.) and then fill in the parameters
for number of teeth, bore, LTB, hubs, keys, setscrews, etc. Eventually I
will automate the process, but I haven't had the time to work on it. Let me
know if you want a copy.
