| Popis: | Introduction. The work objective is the field research of vibrowave processes in the utilization technology of assembly units (AU) of the agricultural machinery. The reducer from SK-4 discarded combine harvester is used for testing. Materials and Methods. A reducer component complex of different sizes and configurations, various materials, varying oil-consumption pollution is considered. After the exterior check of these test pieces, their weighing was performed. The parts information was registered in the related tables. After weighing and checking, the following stage - vibration washing and clearing operation - was carried out. Various components of cleaning the reducer parts surfaces were used for that. They differed both in composition, and in appearance. The following components: PT15х15, porcelain (mm d=6-8.) and steel (d=5-7mm.) full-spheres, were selected and applied. These experiments were performed in the laboratory of the Engineering Technology Department of Don State Technical University. UVG40 vibratory cleaning washers (chamber volume is 40 l) and UVG4x10 (4 chambers per 10 l each) are installed in this laboratory. Both chambers were activated as not only small-sized pieces, but also large-size ones were involved. Cleaning was conducted in 3 steps. The authors consider this quantity optimum for cleaning the rundown reducer parts. Each period was equal to 90 minutes of the chamber operation with the pieces and an abrasive cleaning component. 2% soda ash solution was added to the operation environment. It helped to soften the oil-consumption pollution for its fastest removal from the reducer parts surfaces. After every step, pieces were removed from the cleaning chambers, washed and dried. Further on, each piece was weighed and compared with the basic weight; its degree of the purification of both external and internal part surfaces was studied. Research Results. On completing the cleaning operation, a comparative analysis on the cleaning degree of the surface of each component was carried out. The most effective component was selected. Discussion and Conclusions. Within the framework of the study, the most effective components of cleaning the reducer surfaces are selected. |
