Robot Quick Build Session Transmission Assembly Instructions Produced by Ed Latimer, Team 476 Ken York, Team 476 Ron Markum, Team 1750 Special Thanks to Oklahoma State University College of Engineering, Architecture, and Technology
Transmission Assembly Instructions Step 1 – Watch the instructional video for assembling the Tough Box transmission on www.andymark.bizwww.andymark.biz Step 2 – Proceed with putting the transmission boxes together. You can use the video in ‘pause’ mode, or you can use this presentation.
Parts and Tools Needed for One Transmission Box
The side of the bearing with the ridge faces up. The smooth side of this big gear faces up The side of the small gear with the raised hub faces up. Use the non-mar hammer. Note: If none available, tap with a regular hammer using a block of wood as a cushion. The small shaft goes in the bearing without any small holes around it in the cover.
Install both bearings with the ridge side facing down. Spread the grease around by turning the gears. The side with the raised hub faces up. Apply a small amount of grease to the gears. Excess grease can spin off and might ruin the plastic cover’s finish. A regular hammer can be used to put the C- clip on the shaft.
Snap/push the cover down over the bearings. Tighten the bolts using a medium clutch setting on the cordless drill. Note: Install the 2 nd bolt on the opposite corner of the 1 st bolt to pull down the cover corners evenly.
Make sure the shaft spins free or you’ve made a mistake. Repeat for the 2 nd box.
Gather these parts and assemble as follows. Repeat for 2 nd motor. Square keystock fits between prongs in clip. Push on with a nutdriver or socket.
Use the screws with thread-lock coating to mount the motor. Start the first screw but don’t tighten it yet. The two ‘open’ holes in the motor plate line up with the screw passage holes in the cover. Put in the second screw and then tighten both of them.
Repeat for the 2 nd motor but make a ‘left’ and ‘right’ facing transmission box.
Gather these parts and assemble as follows. Repeat for 2 nd box. Sprocket from kit of parts Be sure and use the washer as it keeps the sprocket from sliding off. Make sure the gear teeth are on the outside.
Leftover parts from each transmission box for an optional 2 nd motor and 2 nd sprocket in case you want to add them later.
The bottom mounting bracket goes on the side closest to the output shaft, the side opposite the motor. Take off the two screws, put on the bracket, and re-tighten them.
The top mounting bracket goes on the opposite side. Again, remove two screws to install the bracket. The motor should be on the top half of the box and the output shaft on the bottom half. Repeat for the 2 nd motor.
Finished product, ready for installation on the frame.
