Truck development. Is it possible to combine 2 35kg/cm servos together to end up with 70kg/cm?

Question

Physics

There are 2 servos for 35 kg/cm, and for the project I need a servo for 70 kg/cm, is it possible to somehow combine my 2 servos so that they give a total of 70 kg/cm?

Answer 1

If I understand correctly, you need to mechanically combine the servos into one more powerful one. I think it can be done, but the solution will not be simple. If you simply connect the shafts, then due to errors in the mechanics and electronics, the servos at the destination will begin to "fight", one turns forward, and the other believes that it is already a flight, and turns back. Most likely, the servos will not live in this mode for a long time. Perhaps the servos can be combined through a differential. If you imagine the rear axle of a car, then the servos should stand instead of wheels, and the output is a cardan shaft. Then the load will be distributed equally, and the position of the servos can be independent. It should be borne in mind that the servos must rotate in opposite directions. Well, the main question: will such a system be cheaper than a more powerful servo?

Answer 2

What difference does it make what size and weight they are? power is supplied separately, you need something like wiki.amperka.ru/%D0%BF%D1%80%D0%BE%D0%B4%D1%83%D0%...
