Whoops, knew about the 1/2" hex but not the 3/8". Guess I'll settle for just the round variants then.

Re: What COTS parts would you like to see?
 

Since they're just spacers, can't you use the hex spacers on round shaft? :)

7075-T6 is the best alloy for aluminium gears available.
Yes, perhaps small gears such as those gears up to maybe 24 tooth could have the option of being replaced with drop in 4140 gears.

Re: What COTS parts would you like to see?
 

Every broken gear picture on CD has the teeth sheered off. I've never seen the body of a gear crack. So, the failure mode seems to be the teeth. Would 4140 steel gears with lightening holes be an option? How much more would it cost?

After going through a season thinking "man, I wish we had a -----", I'm totally blanking out.

The tube spacers would be super useful, for sure. That would have saved us a lot of pain this year. Other standoffs would also come in handy.
Totally separate CIM mounting holes on the WCP gearboxes- the CIM bled into the 12t pinion mounting distance from the 14t distance, causing massive friction.
3/8" hex versahubs, however the 3/8" hex to 1/2" hex adapter by WCP solves a lot of 3/8" hex issues.
More GT2 belt pulleys would be great; WCP sells 12t pulleys and belts but not the larger hex broach pulleys we need! Small 12t 5mm HTD pulleys would also be nice.

Right angle output stage for the Versa-Planetary gearbox, not an adapter but an integrated output stage that takes the place of the normal output stage.

Re: What COTS parts would you like to see?
 

This would be very useful, depending on the input motor and the reduction there would be significant torque on the bevel gears( if bevel gears were used). It might be difficult to find small enough bevel gears that would be able to take the torque.

How efficient are bevel gears? I've heard worm gears can be quite in-efficient.

I know team 33 made a tutorial on how to modify a versa-planetary and a drill/driver right angle adapter to accomplish this:

Re: What COTS parts would you like to see?
 

Cycloid stage in a versa planetary. Couple that with a right angle adapter and you've got a monster of setup to lift arms etc.

VersaBlock with 1/4" drop when flipped allowing drop combinations of the following when mixed with the current 1/8" flipped:

1/16", 1/8", 3/16", 1/4"

Re: What COTS parts would you like to see?
 

1/2" hex bore bevel gears.
I'm sure there are others I could think of, but that's what pops into my mind right now.

Re: What COTS parts would you like to see?
 

The attached gear was pocketed on each side .112, leaving a web thickness of .150.

Re: What COTS parts would you like to see?
 

That is a 7075-T6 gear isn't it?

Andymark sell a few gears with weight saving holes in, I think in the weight saving your not going to be able to reduce enough weight to make it equal to an un-weight saved Aluminium gear however it would still be great to do some experimentation

Team 254 did some really nice weight saving for the large VEXpro aluminium first stage gear in their CIM-over wheel gearbox, I'm not sure if they had any problems with any gears during the season.

We probably don't want to hi-jack the thread with a Aluminium gear vs steel gear debate :)

Re: What COTS parts would you like to see?
 

Is the slot to prevent the gear from resonating?

Re: What COTS parts would you like to see?
 

10/10 would buy.

Clamping hubs and other hardware. I've been waiting for an FRC supplier to do a clamping hub for *years* and, so far, been disappointed.
