Hydraulic technological machines with adaptive drive structure

In a large group of technological machines, drive provides two interlocking working movements. In metalworking, the working process is provided by two movements of the cutting tool relative to the forms or details. As a rule, this is due to the rotational and forward movements. The ratio of speeds of these movements, the ratio of two movements, or the ratio of the brought capacities to each of these movements can be the significant indicators of working process, having the optimum value. The method of automatic maintenance of the ratio for a hydraulic actuator with two engines is considered in the article. Schematic diagrams of the drive for some technological machines are considered. Based on the example of the device intended for processing of curvilinear surfaces, the process of automatic control regulating thickness of hydraulic actuator having adaptive structure is described. The efficiency of self-regulation at rather simple circuitry decisions is shown
