In this article the author considers the gasdynamic bearing with the spiral flutes which active zone is formed by two close located firm surfaces, on one of which spiral microflutes are executed. The oblique-angled system of coordinates consisting of logarithmic spirals and circles is entered. For each dyad a flute crossing point values of powers of viscous friction were received and further their main moment of resistance concerning a bearing axis is calculated, expression for the main moment of forces of resistance is found in a smooth layer. In work the algorithm, allowing to calculate the main moment of powers of the viscous friction developing in a lubricant layer of the gasdynamic bearing with spiral flutes is received.
