BRAND-NEW CONSTRUCTION PRINCIPLE OF FRICTIONAL UNITS
The construction principle of the frictional units, which can significantly increase the operational characteristics of various machine-tools, mechanisms, drives, special equipment, and vehicles, is proposed. The brand-new principle is based on the use of the complex relative movement for the effective areas in the frictional couples of the frictional units. Unlike the simple relative movement, the complex relative movement for the effective areas in the frictional couples of the frictional units can improve the operational characteristics of the frictional units to a brand-new level, stand by further development and expansion of application scope for such units of the machine building. The brand-new construction principle of the frictional units can be used for smooth transmission of torque, smooth change in rotation frequency, conversion of mechanical energy (of movement or rotation) into thermal energy, reduction in linear and volumetric wear of frictional couples, reduction of vibration, acoustic noise, and contamination of frictional areas with third-party substances, transformation of rotational movement into translational movement and vice versa in frictional drives and various balancers, compensators, and gyroscopes.The mathematical model of the complex relative movement for the effective areas of the frictional couples, which is the basis for the brand-new construction principle of the frictional units, obtained for the most successful kinematic diagram of a frictional unit, is proposed. The kinematics and the dynamics of the frictional units with the complex relative movement for the frictional surfaces of the frictional couples are considered. The analysis of thermal processes and wear of the frictional bodies during the complex relative movement of the effective areas is carried out. The comparative analysis of the noise characteristics of the frictional units made by using traditional construction principles and the brand-new construction principle is carried out.
