“…Elimination of worn spots of non-traditional shape, as well as improving the operational properties of the working surfaces of parts using adhesive polymer composites has recently become increasingly wide [1,2]. At the same time, based on the working conditions of the friction surfaces, composites with various properties or their combination are required, which makes it necessary to conduct full-scale experiments to select the ideal compositions.…”

The increase in the adhesive strength of the epoxy and sand composite is equally regulated by the content of the sand component and the dispersiveness of its particles. The wear resistance of the composite is mainly determined by the size of sand particles, and the concentration significantly affects the degree of resistance to abrasive wear only when the fraction dispersiveness is equal to 1 mm. The maximum adhesive strength and wear resistance are characteristic for a composite of the following composition: 30 pts. wt. epoxy glue and 70 pts. wt. natural sand with a dispersiveness of 1 mm.

Restoration of case parts of machines significantly reduces the cost of their repairing. The present paper proposes a method for restoring case parts using the repair size method. Depending on wear degree, the fitment holes are bored to three repair sizes. The prepared hole is inserted with a new bearing, the outer ring of which is covered with a polymeric coating of the appropriate thickness ensuring the fixity of the joint. As a result of theoretical studies, the model was obtained for the formation of a uniform polymer coating on the outer surface of a rotating cylindrical part. The facility and technological equipment were developed for applying a polymer coating of F-40C elastomer solution onto the outer surface of the rotating bearing. The facility includes screwing lathe 1K62, centering drift pin, bath and magnetic holder MV-V. The holder is designed for mounting a bath filled with polymer solution and its plunging movement when rolling bearings are immersed in polymer solution. The drift pin serves for centering and assembling bearings. The assembled drift pin is inserted into the chuck of the machine rotating the pin when applying polymer coating. The screwing lathe 1K62 is equipped with an INNOVERT frequency converter of H3400A05D5K type, which allows adjusting infinitely the spindle speed from 0 min-1. The paper presents the results of experimental studies on the F-40C elastomer shrinkage, the parameters of the mode of immersing parts into its solution, the dependence of the geometric parameters of the formed polymer coating on the components of application and adhesion modes for polymer coatings based on F-40C elastomer solutions of different viscosity. The acceptable thickness of the polymer coating of elastomer F-40C on the bearing 209, ensuring the non-failure operation of the restored seating with a cyclic radial load of 20 kN is 0.1 mm.
