Here I'm sitting in my swivel chair, explaining to you a drive that works with air. A swivel drive is called for sure. Listen to me, then it's less obscure. Hello and welcome to a new video about pramatics. This time we are going to talk about swivel drive. Pramatics swivel drive. With this little ride, I already opened and I'm going to explain how this is working. So we are talking about swivel drive. We already got something which did rotate, rotors cylinder and a swivel drive, all the rotates because it's a swivel rotate. So basically it's round. Should be round. Then there's the rotating shaft. Here this is fixed and there is some sort of wing flap. Some like this. This is sealed here and here we got hold. This is one position. So here we cut it open. It is working pretty straight forward. This shaft can rotate. It's the flap and the shaft. They are fixed to each other. If we are adding in here air and here the air can exhaust, this flap will simply turn until it's the mechanical limit on this side. And if we do it the other way around, it turns the other way around. So this is one position and the second position would be here on this side. Like I said there are ceilings. They have the same task like the piston ceiling and that's it. Swivel drive. Working pretty well. Pretty straight forward, right? So rotating angle is from 0 to 270 degree. It's not a full rotation because there is this mechanical barrier here which has to separate the pressure side from the relief side in either way. 0 to 270 degree. And of course there is also the torque and the torque can be 0.5 Newton meter. It's too small and the maximum torque depends a little bit on the size of the flap of course but it would be 20 Newton meters. So a little bit less than the rotor is a linda. Also at 6 bars. Well the size, this is of course the determining, the area of the flap here. This defines at a certain pressure the torque. And what also helps is of course the radius. Because if the force applies a little bit outside, more outside, I have more distance and more torque. Swivel drive. Next time we are going to talk about symbols. We are going to talk about symbols in of our chromatic elements, working elements. And then, well that's it for the working elements. What we are going to hear in this topic. So we had cylinders, we had special cylinders like piston rods less cylinders. We had linear drives, we had them rotor is cylinders and we have this wheel drive again. Like said, next time the symbol for this. For this time, thank you for listening, goodbye.
