Analysis and selection of similarity criteria for modeling of polymer coatings formation processes in repair of agricultural machinery
The article reviews the main similarity criteria for simulation of real fluid motion processes; the conditions ensuring the uniformity of the coating have been formulated. The process of polymer coating forming from the polymer solution on the bearing is recommended to analyze using Reynolds number of Re. The difference between the estimated and actual values of parameters for polymeric coating application does not exceed 10%.

Way of reconstructing case parts of agricultural machinery with poly-meric materials
The authors suggest a way of reconstructing basic parts using the repair size method. Filment bores are rebored for three repair sizes according to the wear rate. The processed bore is equipped with a new bearing, its outer race being covered with a polymeric coating of adequate thickness providing the junction immobility. The theoretical research has resulted in a model of forming an even polymer coating on the external surface of a rotating cylinder part. The article presents the results of the experimental studies of the dependency of geometrical parameters of the formed polymeric coating on the elements of the application regime and the adhesion of the polymeric coatings made of the F-40C (Ф-40С) elastomer solution having various viscosity degrees.
