Two-disk test rigs are used to investigate the motion types rolling, sliding and tumbling.
They can be used, for example, to model the motion processes on tooth flanks.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Two-disc test stand “A135<\/strong><\/td>\n<\/tr>\n
The two-disk test rig “A135” from Roell-Amsler can be used to investigate the motion types rolling, sliding and tumbling.<\/td>\n<\/tr>\n
As standard, two 10 mm wide discs with a diameter of 40 mm are pressed together. Theoretically, the lateral surfaces of the disk can have any conceivable geometry. The frictional torque is recorded continuously. Wear can be determined after the test by weighing or measuring. With the switchable eccentric, a pulsating radial load (abrupt lift-off) can be superimposed on the rotary motion. A second eccentric allows periodic axial back and forth movement of the upper specimen. When the upper shaft is stationary, a bearing half-shell can also be used instead of the cylindrical specimen in order to test plain bearing materials and coatings, for example.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Two-disc test stand “2disc<\/strong><\/td>\n<\/tr>\n
The modern two-disc test rig “2disc” from Optimol-Instruments, Munich, can be used to investigate the motion types rolling, sliding and tumbling. As standard, two 10 mm wide cylindrical discs with a diameter of 45 mm are pressed together here. Theoretically, however, the shell surfaces of the disks can have any conceivable geometry. For higher pressures, crowned washers are used, for example.<\/td>\n<\/tr>\n
The frictional torque is recorded continuously. Wear is detected during the run via an inductive sensor. After the test, the mass wear can be determined by weighing.<\/td>\n<\/tr>\n
In contrast to the old two-disk test stands from the Roell-Amsler company, this state-of-the-art tribometer has significantly greater performance data and much higher precision.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
