MACHINE TO TEST MATERIALS FOR FRICTION AND WEAR Russian patent published in 2010 - IPC G01N3/56 

FIELD: instrument making.

SUBSTANCE: invention relates to test equipment, particularly, to test machine intended for testing materials for strength and wear. Proposed machine comprises base supporting motor coupled with lower specimen fitted on the shaft via rotary pickup of torque and with upper specimen fitted on output shaft of swing carriage. Load is applied to specimens with the help of loading device, for example, a spring-type loading device. Aforesaid carriage is installed on rotary platform pivoted to movable support to turn relative to vertical axis crossing the center of symmetry of specimens by pivot-joint. Pivot axis cross the center of symmetry of upper specimen perpendicular to its center of rotation. To compensate for platform angle of turn relative to aforesaid carriage, the latter is drive via compensating, say, gimbal drive. Additional drive is arranged on the support to turn platform about pivot-joint axis.

EFFECT: expanded performances, higher data validity and reliability.
