A change in the direction of the working body movement of the chuck is provided by using a planetary transmission with intermediate solids of revolution. The proposed design has a built-in two-section ball transmission unit with various slowing-down elements, which provides a reversal during operation. Keywords reversible thread-cutting chuck, planetary transmission with intermediate solids of revolution
