UH Capstone - Team 23

Currently, we have worked on the analysis for the project. We had some initial looks to make sure the lug nuts are able to turn and we went based on that. Now we are looking into the exact predicted torque and the issues of under and over tightening are becoming an issue. Another obstacle we are tackling is the cost. We have overlooked some of the costs and are trying to change the design in a way that would allow us to save money and still be functional.  As of now, our design has a central driver gear and 5 driven gears. In this layout, the torque from the drill is split evenly into each gear and then doubled from the gear ratio of 2. This in theory is ideal, but there is still the possibility of a gear initiating before the rest and this could lead to over tightening. To combat this we have a torque limiter on the ends of the sockets. This would allow us to make sure that each lug nut is not being over tightened and it will prohibit any gear from not being tightened properly. ...

   Our team has changed projects a few times, but we're finally settled and approved for our latest: a multi-spindle that you can use for removing and installing lug nuts! Since our progress report presentation, we've finalized the vehicle we're going to model the deign off. This is the most important step, primarily because of how many unique factors the vehicle demands. Specific spindle arrangements, differing depths, manufacturer keys, housing size and geometry, and simple availability have enormous impacts on the specifications the multi-spindle would have. From this, we've created a CAD of initial designs that we want to iterate upon as we explore options regarding the torque issue.  One design was a single-driver gear and the other was a drive shaft with multiple driver gears. Each design is still in its preliminary phases, but we are continuously working on refining them. Currently, we are looking into what gears we can purchase since the machinist cannot manufac...
