Spur gear?

[willrnewman]

Hi I’m trying to find a gear 26t 49mm O/D

[willrnewman]

I’ve attached a picture

[jboggs]

Where have you looked?

[willrnewman]

I’ve tried the 3 different companies, plus I’ve spent hours looking on the internet with no luck!! Any help would be appreciated.

[jboggs]

Have you identified whether it's metric or imperial (inch) standard?

[Kelly_Bramble]

I doubt it's an off-the-shelf gear.

Probably need to find somebody that can reproduce it from what you have

It’s used to to drive a limit switch on an electric motor, pretty sure they would be massed produced, if you knew the part number probably would find it straight away.

[willrnewman]

This is the switch

[willrnewman]

No I haven’t, how would I go about this?

I agree with Kelly. I don't think its an off-the-shelf gear. From the photo it looks like it is custom made for that particular product. You could try the switch manufacturer, or whoever owns them now.

[willrnewman]

The switch and motor manufacturers are the same people. It’s a basic setup with a gear from the motor driving an intermediate gear which drives the switch all the same o/d. I’ve taken a picture of the maker mark.

From that picture it looks to be die cast and probably in aluminum or zinc.

If a replacement cannot be found then you would take the gear to a machine shop and ask for a reverse engineered gear built from the existing example.

I've had to make something like this a few times recently.

It looks like the gear has 26 teeth; a fairly normal configuration.
The only other thing a machinist would need to know is the diameter.

Then I'd go to Boston Gear website, and find the one that is closest to the bore diameter / hub configuration, and modify that to fit.
A fairly simple job really. (uumm... if you have the proper tools )

[dalecyr]

Went back and read the original post.
(should've done that first).

26t and about 1 15/16" OD.
That doesn't seem difficult to find.

Just have to modify (probably) the hub/bore to fit your application.

Good luck in finding. It happens so often with me, as soon as a certain thing is needed, then it is nowhere to be found.Recently, I needed a linear actuator to automatically close the door and barely found a website where I could order exactly the one I needed. But I spent 3 days looking

Hi
I'm new in this forum but it seems to me you cannot find an off-the-shelf part why you don't use planetary gear for reducing the numbers of turn?
