OBRABOTKAMETALLOV Vol. 23 No. 3 2021 MATERIAL SCIENCE EQUIPMENT. INSTRUMENTS 6 1 4 and silicon. The increased aluminum content is due to the presence of aluminum powder in the annular gear material, the increased silicon content in the abrasive layer material is due to the presence of silicon carbide crystals. Conclusion 1. Based on the results of a literature review and the results of a study of the chemical composition of fragments of imported hone, it was found that chloroprene and butadiene-nitrile rubbers, the composition of which is close to the imported analog, may be used as a hone material. 2. Studies of the mechanical properties of laboratory specimens showed that these materials, with the addition of various fi llers (humidifi ers, binders, stabilizers, softeners, vulcanizing agents, accelerators, etc.), provide the necessary Shore hardness; for an abrasive layer, this value is 93–95 units, for a annular gear of hone it is 85–88 units, tensile strength is 14 MPa and 11 MPa, respectively. 3. To refi ne the formulation and production technology of the imported hone domestic analogue, a two-teeth laboratory mold was made, which allows performing the following operations: molding and heat treatment of the abrasive layer, joint molding and heat treatment of the abrasive layer and the annular gear. 4. It is established that the preliminary vulcanization of the abrasive layer has a signifi cant eff ect on the strength of its adhesion to the annular gear material: with an increase in the degree of vulcanization, the adhesion force decreases. In this regard, the joint vulcanization of the abrasive layer and the annular gear is adopted in the technological process. 5. The required thickness of the abrasive layer is obtained by rolling followed by profi ling in a mold without vulcanization. Further technology is implemented by injection molding and pressing methods followed by vulcanization. 6. An experimental mold for the manufacture of a hone model with a 6 mm module, with a number of teeth of 14, is designed and manufactured. The following Shore hardness values were obtained: the abrasive layer was 95 units, the annular gear material was about 90 units. The hone model was successfully tested during trial honing of a gear wheel. 7. After seven days of exposure in a kerosene-oil medium used in production conditions for honing operations, the hardness of the abrasive layer of the geared hone and the annular gear material did not change. 8. The developed formulation of elastic gear hone and its manufacturing technologies are accepted for testing under production conditions. References 1. Kalashnikov A.S.
