【 摘 要 】

The aim of this work is an experimental verification of the basic operations of a contactless radio wave method for determining the technical state of gears. To implement this goal, a specially developed experimental device is used. It uses generators with frequencies of 12 GHz and 32 GHz to obtain microwave sounding radiation. The excited electromagnetic oscillations of the microwave range are channeled by means of a circulator into the path of the primary converter. It is made in the form of a circular waveguide. Non-contact radiowave method of gear working condition control is developed. This method is based on the online treatment of the signals received after detecting probing radiation of microwave range deflected from gear teeth. Dependencies of signal amplitude on distance between face of the emitting waveguide and controlled surface, received by experimental way, are presented. These dependencies was approximated. Depending on which primary transducer is to be simulated and to which of the two ranges the length of the path traversed by the reflected beam falls, one of the four dependencies is selected, which calculates the weighting factor for the specific reflected beam. As a result, the developed control system of the gears of the multipliers will allow obtaining up-to-date information on the state of the gears during the operation of the desalination plant. This in turn will reduce the probability of failure of this mechanical system and will allow you to derive an economic benefit from its use.
