gear pin mechanism

[SAEEDGH]

hi. i want to design a gear pin mechanism like picture.
is there any standard for
pins pich and diameter and
gear module and pitch diameter
and power transmission capacity

There's Tsubaki and a Taiwanese copy. Looks like those are the only companies that make them, so I doubt that there's any available standard.

Tsubaki's web site has some nice pictures and exploded views. Shouldn't be so very difficult to reverse engineer from first principles.

Probably cheaper faster better to buy from Tsubaki.

It's called a lantern gear; a cycloidal meshing mechanism, sometimes used with roller chain as a rack element.

There will be nearly no standard components because they aren't suitable for significant power transmission, so there isn't much in the way of automated equipment to make them. Lack of automated equipment to make them means no need to standardize. They can transmit large forces and are used for bicycle sprockets, though usually modified to ease shifting on multi-sprocket gear trains.

I would look to borrow roller chain standards. Your larger gear with the pins will be a complete custom part.

What is the objective of this design?

Pin gear sprockets for use with roller chain have somewhat different tooth geometry due to the single tooth transmitting forces, but it would be a reasonable place to start. Once again, contact Tsubaki they have experts available.

I've never heard that term before. Thanks.

Let me refraize the question.
What is purpose for using this style mechanism?

Thanks to Google for mixing it in with camping equipment lighting. Sigh.

They pre-date Leonardo DaVinci, who depicted them in his sketches.

Nexen also has a variation on this. I think that it could be possible to engineer the components, but not sure why. If you are going to produce these and compete in the market, you would already have this knowledge, and the time involved to engineer for a single usage doesn't seem justified.

thanks a lot. lanter gear was a helpful and key term for me

thanks a lot. it was so helpful

I would suggest to run the numbers like sprocket and chain. Light loads
