In the article, a planetary gearbox is adopted to ensure the efficiency and compactness of the vas deferent drive. The number of teeth of the sun gear Z 1 =12, satellite Z 2 =12 and main gear Z 3 =36 with a module m=3 mm is checked for compliance with the condition of assembly and proximity to the number of satellites equal to K=4. Verification calculations of the sun gear teeth and the satellite axis for bending are carried out, in which the strength condition is met with a reserve of s F =24.93 MPa£[s F ]= 465 MPa – 18.5 times and s u =20.26 MPa£[s u ]= 60 MPa – 2.96 times. In addition, taking into account the strength calculations, the dimensional values of the planetary gearbox units of the vas deferent tube are determined.
