hello ))
dark months are over and i overcome procrastination and did start to build one more tracker.
i would like to share the progress in this thread.
frame construction, parts used and kinematics can be seen in video of the first tracker built 5 years ago.
it is still working and has harvested lots of kilowatt hours.
this is second one, built a year later.
tracker is built mostly from car/tractor/truck parts that can be obtained in scrapyard.
only custom parts to be machined are the worm shafts that work with starter ring gears.
this time instead of truck hub i will use a part from forwarder tractor.
it is basically a big ball bearing and has many mounting holes, some smooth and some threaded. very convenient.
i only heat seated a starter ring gear on it.
car flywheel works fine for altitude adjustment, but it has rather narrow and fine teeth, i will try some big gear instead of flywheel for more contact surface and because i do not have any flywheel at hand. ))
making “cradle” for center tube, it will sit on eight 60207 bearings.
machining contact surface
four M18X2.5 bolts will hold them in place.
making 42mm holes for spherical bearings with grooves for circlips.
progress so far, need to purchase bearings, circlips, bolts to continue.
