DEVELOPMENT AND RESEARCH OF WORKING PARTS OF JOINT CUTTING MACHINES WITH CYCLOIDAL MOTION

The development of a country's economy largely depends on the pace and efficiency of construction work, which, in turn, is determined by the extent to which innovative technologies and techniques are used. This work is devoted to justification of the basic parameters and the development of a new working body for a machine for cutting joints in road surfaces. A design with cycloidal motion is proposed, which intensifies the destruction process due to the vibrational impact of the cutters on the material being processed. The use of such a working body provides a vibrational effect, increases the cutting speed, and reduces the energy consumption of the process. As a result of intensifying the interaction between the working body and the material, it was possible to reduce the energy consumption of cutting by 1.13 times, and increase productivity by 1.18 times compared to analogues.
