Abstract
The article presents the results of research to develop a method and means for monitoring the in situ condition of the joints braking devices in accordance with the gap value and the angle of rotation between segments of "Straight pin" kinematic pairs. It was obtained a mathematical model of the overlap area dependency of the sensor of plates from their relative displacement in the parameters With the help of capacitive sensors it is possible to control not only the hinged joints, but other mechanical parts of the mine winder that allows you to create the monitoring system of the technical condition in real time.
