Hypoid gear vendor/mfr in North Texas?
Hypoid gear vendor/mfr in North Texas?
(OP)
Can anyone recommend a good hypoid gear vendor or manufacturer in North Texas (Dallas/Fort Worth)? I've got a worm gear set in a handheld medical device we're developing, and the noise and efficiency have proven too difficult a problem to tackle. I want to investigate a different type of gear, and the hypoid seems like a good candidate.
My application is 100:1 ratio, motor speed ~6000 rpm, load at the end of the drive train about 6 oz-in (40 Nmm).
Thanks in advance to any advice or helpful links anyone can provide!

Take a look at Helicon gears.
I wouldn't worry too much about location, what with Fedex and UPS and such.

Sounds to me like you need a gear design consultant; before engaging the services of a manufacturer. It could save you a heap of costly experiments.

Either way, I agree with the above, worm drives are usually very smooth and quiet.
What materials are you using? Steel on steel can 'bite' and get a bit bumpy...
A threadrolled worm and vesconite (or similar plastics) worm wheel yield very good (quiet) results.
Hypoid gears have greater axial forces to contend with as well...

@bithkits - The audible noise/vibration is unacceptably loud. Electrical noise is not a problem. We're using a brass worm and a nylon gear. Nylon was chosen by the vendor specifically for low friction and quiet operation. Is there any other names I can search for vesconite as?

Generally you have to bring them in.
I'm really surprised to hear that there has been no design validation and you've left all the design work to the manufacturers......IMHO that is not their job, to do your design work for you. If this is OK with you then you'll only 'get what you've got.'
For critical applications involving worm sets; it is most unwise to mate parts from different manufacturers. It is most important that worm sets are made as a matched set. This can only be done properly under one roof on the same machines. The same is required of bevel gears particularly spiral & hypoid sets and even helical gear pairs.

Here is link to the AGMA's list of consultants: http://www.agma.org/membership/consultant-list/
I know that one of them, Ray Drago, has had a lot to do with medical related gearing so I figure he'd be the first consultant to speak to.
