At the same time, compressed air is supplied to the channels of the brackets 14 and 17j, which are deflected by the elastic spring of belts 15 and 18. Tension transducers 16 and 19 vibrate the KPpocliT electrons proportional to sk and radial loads P and Pg "and the frictional moment of the MTP in the bearing is transmitted to the washer 7 and, deflected by an angle f through the piezoelectric sensor 23 to the registering device 20, the non-compensation signal is transmitted to the input of the amplifier 13, the output current of the coils of the electromagnet 11 creates a compensation moment MR. The moment of friction is transmitted through the amplifier 13 to the recording device 2O, as well as C11 signals, proportional to the angular velocity u) and loads PQ and 2, allows you to determine gr "4 - q ii iiOCOC of the moment of friction from the parameters rp-f); t (PJ-, i (FJ. claims This is due to the fact that, in order to improve the accuracy of measurements, the devices for axial and radial loading are fixed on elastic bands scaled in units of axial and radial loads for determining elastic deformation under the action of a loading air jet.
