Hi guyz, I need some help in choosing the shaft couplings to connect the motor to the gear and from gear to the wheel. The motor shaft is 11 mm and the gear shaft is 24 mm. (Max torque 2 Nm, Max speed 70 rpm) Output of the gear shaft is 32 mm and the wheel shaft is 30 mm. (Max torque...

We want to have equal weight on each wheel. The platform will be rotating very slowly following the sun.

Hi everyone, I'm working on load distribution of what to be put on a platform. The platform will be rotated by the wheels placed at the circumference of the platform. The loads that need to be put are the optical components which have mass of 1 ton which will cover 8 m x 8 m area and...

I have just gone through the calculation Isn't the inertia for a disc I = 0.5 m*r², which will give 200 000 kg m²? I will use 30 cm diameter wheels for this application and with this precision of 0.01 degrees, the wheel will have about 1.09 RPM at max tangential speed and 0.02 RPM at min...

Thanks DickL This definitely will help me in estimating the torque needed for the platform

Thanks DickL for the answer. Yes, the tracker will have a control system which will control the position according to sun. Can you please explain me more how can i calculate the drag forces and accelerating the mass?

Hi all, I am planning to build solar tracker which will have a platform that rotates about vertical axis according to sun. The platform should have max tangential speed of 1.03 m/min and min tangential speed of 0.017 m/min. The platform has a mass of 4 tonnes and radius of 10 m and can be...
