The main function of the rigid shaft coupling is the safe and backlash-free connection of two shafts by means of friction. For example between a drive shaft and driven shaft and mainly to transmit torque. Shaft couplings consist of a connecting sleeve and two external clamping systems. They are not separable like flange coupling. The external clamping systems generate a backlash-free connection by pressing the connecting sleeve onto the shaft ends. The external clamping system does not transmit any torque or moments between the shaft ends, they just provide the necessary clamping forces. Those external clamping systems are not part of the flow of forces, but the connecting sleeve is. The couplings have to be installed by moving them onto the shaft ends followed by tightening of the external clamping systems via bolting. To achieve proper operation and a sufficiently high coefficient of friction, the contact surfaces at the shaft extensions must be free of grease, dry and clean....

It is hard to imagine operating electronic devices without the help of chargers. Anyone who wants to shorten the battery charging process, make it more effective and at the same time energy-saving should be interested in new generation gadgets. The charger in GaN technology from Dudao is an absolute hit on the market, which has a real chance to revolutionize it. Why? Because it uses the power of gallium nitride instead of silicon. GaN is a semiconductor material that not only improves the efficiency of the charging process, but also requires much less energy and takes up minimal space. Therefore, it is ideal for mobile use, also at work or traveling around the world. It is compatible with sockets around the world where electrical voltage standards range from 100 to 240 volts.
