WIRELESS SYSTEM FOR MEASURING TEMPERATURE OF PLAIN JOURNAL AND THRUST BEARINGS

摘要

FIELD: machine building.SUBSTANCE: wireless system for measuring temperature of plain journal and thrust bearings comprises at least one temperature measuring device (1) integrated in the load-carrying element of a plain bearing (a packing block (2) and/or a thrust pad (3)) and connected to at least one device (5) for transmission of the measured values as well as a device (6) to receive signals and transmit them to the automatic control system and a power supply source for the above devices. At least one device (5) is also integrated in the load-carrying element of a plain bearing. Every temperature measuring device (1) together with the respective device (5) for measured value transmission is fitted by a power supply circuit. The device (6) to receive signals and transmit them to the automatic control system and the power supply source equipped by an electromagnetic wave emitter (9) are installed at a distance from the said load-carrying element of the plain bearing while the possibility is provided for the receipt of signals from the device (5) and transmission of electromagnetic radiation for EMF excitation in the power supply coil of the device (1) and device (5).EFFECT: provision for temperature measurement and data transmission to the automatic control system without mutual mechanical interaction of bearing parts and elements of the temperature measurement system which improves the system performance reliability.6 cl, 2 dwg
