So far, pretty good
. One semi complete transmission done on the 19th. Not bad at all. Just need at most 1 more week to finish this one.
Let's see, I like the shape, it save lots of weight by cutting away the corners... Ah, 2 place for motors to screw in, so its a transmission for two motors... Probably just one side of the robot, so your robot will have 4 motors for the drive system huh?
On to the next picture... The sprocket on the most right is the last stage of the gear box, connecting to a shaft transmitting power to the wheels. The middle 2 gear is the 2 speed sprocket, each level representing one individual gear ratio....
The shaft next to it is where the magic happen. By sliding that shaft with 3 gears on it, you engage one set of gear at a time. The middle gear with the top gear on the right, or the bottom gear with the bottom gear on the right. On the other end of this shaft is where the motors get connected to.
The shaft slightly behind all three of the others is where the 2nd motor connect to. It connect with the left most shaft on the top gear, and transmit power from the second motor to that shaft by meshing the teeth on the top gear. Not sure if you want to, but I bet it can leave that shaft alone by using the pneumatics to slide it off the top gear and clear the rest of the transmission.
Pretty nice gear box this year
. Just make sure its completed.
Patience, grasshopper. They'll get to it. - Rick TYler [more]
