Device for investigation of friction includes unit for fixation of samples with springy plate holders, unit for load setting, unit for long displacement and unit for setting cross displacement. In the unit for fixation of samples elastic plate holders are made flat without turning. Unit for setting load has transmission screw-nut for manual control of position of unit for fixation of samples and setting static normal load. Unit for setting long displacement has electric motor and disc with unbalanced mass. Unit for setting cross displacement connected to spring-supported standpipe has electric motor, eccentric and holder arranged as two halves connected by means of hinge and in basis by means of controlled lever have possibility of fine control of amplitude of cross slide. |
