This article gives a brief overview of the process of flow forming and technical equipment used for its effectuation. Also, the authors noted the main drawback of the existing technology of flow forming, which is evident in the jamming and slipping of deforming rollers. In the paper, we propose a construction of the mechanism, executed in the form of a closed differential gear, which makes it possible to avoid such drawbacks. The main distinguishing feature of this mechanism is that the deforming rollers have a forced rotation from an actuator. The authors obtained an analytical dependence that makes possible to adjust the kinematic chain of the described mechanism based on the absence slippage of the deforming rollers. The mechanism is adjusted by changing the gear ratio of the additional kinematic chain, which includes the regulating and reversing unit for the rotation of the shafts. The regulating and reversing unit can be made in any of the structural designs which allow eliminating slippage of the rollers. Practical recommendations for setting up the mechanism before operation are given. The mechanism can be used both in the stationary production rooms and in the mobile technological complexes in the field.
