I’ve been having some issues with the gear and motor mechanisms in this project. One of the main problems with the setup is that the motor is transferring the torque indirectly through gears, instead of directly to the shaft. To solve this, I am going to buy a shaft coupling that was two shaft collars and a sliding joint. The shaft collars will be different sizes and the sliding joint will allow for some misalignment. Instead of having to tightly press the two gears together, I can align the motor and the shaft of the wheel and transfer the torque directly. This will also reduce the friction at junction between the wheel shaft and its mount.
