Namaskar everyone, Firstly , I am new to forum platform so if any mistake plz guide .Want to discuss(know) on calculation related to rotary table drive. Below are my queries How to calculate torque required to rotate a round table round its own vertical axis , with a mass load of 400 kgs & table load (self weight) of 50 kgs with a dia of 500 mm center support on thrust cum radial bearing & drive given through a pinion of dia 75 mm to a gear of dia 400 mm attached to bottom of table with same table center . I want to know what torque will be needed at 75 mm dia pinion. Note : Dia mention are pitch dia of gears & pinion drive big gear internal .
Impossible to answer without knowing the bearing friction and how fast you want to accelerate / decelerate it.
