3 Speed Plus Reverse Real Working Transmission

thingiverse

This is a cutting-edge, 3-speed transmission with reverse capability. It's engineered to deliver maximum power and efficiency. The transmission utilizes dog clutches and an advanced H-box design. I developed this system for my latest steam kart revision, which will be powered by an air drill engine. The transmission ratios are carefully calibrated at 3.15:1, 1.25:1, and 1:1.6, with reverse operating at a high-torque ratio of 4.0:1. For added strength and durability, I've included both straight-cut gears and herringbone gear STL files. To assemble this transmission, you'll need some essential hardware components: * 8 x 6-32 screws, measuring 3/4" in length * 2 x 5/16 threaded rods, each 1 ft long * 6 x 8-32 threaded rods, each 1 ft long * 2 x 3/8 square rods, each 1 ft long * 4 x 6-32 bolts (or substitute with 4 pieces of 6-32 threaded rod and 4 matching nuts) * 5/16 nuts * 8-32 wingnuts * A single 5mm bolt, approximately 40mm in length, paired with a nylock nut for the reverse idler Additionally, you'll require the following bearings: * 8 x 6003 bearings (17mm x 35mm x 10mm), preferably open or stainless steel to minimize friction * 2 x MR105 bearings (5mm x 10mm x 4mm) for the reverse idler
