Aspects of using single-circuit negative feedback in a safety friction clutch with all leading friction pairs, taking into account installation in crank presses

A feature of the considered option is that, as an analog, a safety friction clutch (SFC) of the usual accuracy of operation in crank presses, in which there is no feedback control device, is adopted. Moreover, this case is applied only with a minimum value of the coefficient of friction, i.e., a con...

Description
Summary:A feature of the considered option is that, as an analog, a safety friction clutch (SFC) of the usual accuracy of operation in crank presses, in which there is no feedback control device, is adopted. Moreover, this case is applied only with a minimum value of the coefficient of friction, i.e., a constructive version of such a SFC should provide for the feedback control device to be turned off from operation under the indicated condition. Taking into account the structure of the ratio for calculating the magnitude of the gain, as well as the fact that for the "ideal" SFC, this value should be variable, it should be noted, taking into account the previous experience in calculating and constructing SFC of this type, that it is most convenient to vary the magnitude of the gain by changes in the angle (pressure angle of the rolling element control device).
