Development of a Method for Measuring Temperature of Elements of a Multiplier of a Wind Power Installation

EasyChair Preprint 2722

Abstract

The possibilities of using a new type of device to evaluate the temperature parameters of the design of the planetary-friction multiplier developed by the authors for a wind power installation are considered. Unlike gear-based animators, planetary-friction gears have compactness, manufacturability, and overload protection, which is especially important for a wind power installation, but they are at risk of high temperatures due to frictional torque transmission. The work presents the design of the multiplier in which, in contrast to the known designs, the contacts between the balls and cages are removed from the bearing interference system, which reduces the risk of heating.

The authors proposed the idea of ​​introducing lubricant into the multiplier, which reduces friction in the contacts between the balls and separators, where the specific pressure is low, and is squeezed out between the balls and bearing rings, where the calculated high pressure is created using a spring, which allows semi-dry friction.

In order to estimate the temperature of multiplier construction elements having small dimensions, the authors developed a contact artificial thermocouple method that allows using its two thermoelectrodes closely located and fixed in the probe to determine its temperature quickly and accurately with contact with the conductive surface of the element. The article provides an analysis of ensuring high measurement accuracy and the result of evaluating the temperature parameters of the multiplier elements during its long-term operation both with and without lubricant. It is established that the design of the multiplier proposed by the authors, when used with lubricant, ensures the heating of bearings not higher than the established standards.
