ABSTRACT
It is characteristic for this planetary gear train (PGT) that it has only one planet with one toothing, as https://www.w3.org/1998/Math/MathML"> II ¯ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429458521/48698ab4-fcf2-474d-9d24-cd80e7124439/content/equ26_0002.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> -PGT (Figure 23.1), but in contrast, the planet meshes with only one gear. Figure 26.1 shows the two possible variants, where either planet 2 or ring gear 3 performs eccentric motion, the first option being used more often. By means of an eccentric (cranked) shaft playing the role of carrier H, the movement is transmitted through the planet 2 to the central element—shaft 1 or ring gear 3. There are also other ways of transmitting the movement between the eccentric and the central element—a cardan shaft (universal joint), a pin coupling, etc.
