Run-in and testing of the machines appear the finishing operations in technological process of development and maintenance of mechanical gears, determining longevity and quality of their work during future exploitation. The article considers the construction of the stand of rolling and tests of mechanical transmissions with asynchronous driving gear that provides recuperation of electrical power from a braking machine till driving. Mathematical modeling of motive and generative regimes of work of asynchronous machines of offered stand has been carried out; the scheme of rolling stands for mechanical gear testing is presented; the construction of braking asynchronous engine is offered. It has allowed defining the size of the recuperation of power from a braking machine till driving. Imitation model of rolling stand is displayed, imitation model of subsystem 'Calculation of the parameters of gear and braking asynchronous engine, composed according the equations, presented in the article' is shown.
