edave Posted May 21, 2020 Report Share Posted May 21, 2020 Hi there I am currently an undergrad engineering student in need of some advice. I am designing a motorized scissor jack and don't know how to approach the gearbox. The torque calculated for the power screw of the jack is 146.77 Nm and the maximum torque the motor can provide is 8.6 Nm with a maximum allowable radical force of 25N. I've tried to use 3 pairs of helical gears to reduce the torque but the radical force is too large. I need the gears to be small enough to fit inside a relatively compact housing. I'm looking for any tips on how to approach this problem will a relatively simple solution that I could approach at my engineering level.
