Re: pic: Manually machinable one-speed gearbox
Looks solid. What are the two small holes in the center for? How is the gearbox mounted?

Re: pic: Manually machinable one-speed gearbox
The two center holes are for the encoder plate, which mounts on the motor side. This is mounted to the frame by using the bolts that go through the spacers.

How is the encoder attached to the shaft? |

Re: pic: Manually machinable one-speed gearbox
Almost impossible to do chain in tube in 2x1 anyway. It's probably designed for 3x1 or larger.

Using something like versablocks as bearing blocks allows for more than ample space in the 2x1 for 2 16t #25 sprockets side-by-side. So this is mounted using the bolts along the bottom? I feel like that could cause the gearbox to flex back, but I could be wrong (something like that happened to our 2012 robot, although it was a slightly different situation). |

Re: pic: Manually machinable one-speed gearbox
The bottom bolts. I don't flex should be an issue, because motor load isn't that cantilevered

Re: pic: Manually machinable one-speed gearbox
It looks like you're trying to direct drive a wheel with this. 11:64 is far too fast unless your wheel diameter is significantly smaller than 4".

~16fps free speed according to JVN calc. We ran that last year.

Re: pic: Manually machinable one-speed gearbox
Could some one explain how you get the chain in the tub. To me it seems like it would be a complex process.

Re: pic: Manually machinable one-speed gearbox
That is one way to do it. I talked to a couple teams at champs (can't remember which) and from what I heard from them it was a largely painless process after the initial installation. Could be something to start a thread about.
I'm sure that no matter which way you do initial installation it's going to be harder than traditional WCD, but the upkeep should be simple. |
