Re: pic: Ungreased toughboxes!!!!

Yeah... I'm adding grease to ours Monday.

I'm also wondering what kind of conditions would make them that bad.

Re: pic: Ungreased toughboxes!!!!

I would also like to know why they weren't greased. I think the lack of grease may not have been entirely to blame for the damage to the gears but it could have accelerated the process. Wasn't the transmission incredibly loud without any grease in it?

We've already greased ours once, but I think we'll do it again after seeing that...

Re: pic: Ungreased toughboxes!!!!

We have four Toughboxes on our robot this year. We lubed them like every other gearbox that 1646 has used, and have had zero problems with wear such as this. There is no reasonable way that this could happen this season if they are properly set up. As I was taught in high school, a properly lubed gearbox, is a happy gear box.

We used them again this year to practice lol. This situation must have some other variables

no you just got very very lucky...

Using these gear boxes without grease is just plain stupid... Never run them without grease, they are rotating at 5000 RPM or there abouts... You NEED grease. No wonder so many teams are seeing gears grinding to nothing, when you have no grease thats what will happen...

Part of the kit. Didn't you at least look at the kit gearboxes?

Re: pic: Ungreased toughboxes!!!!

The first thing we did was machine metal plates for the backing, because last year we shattered/melted it.
