VARIABLE LOADING WEAR AND FRICTION MONITOR (VLWAFM) PIN-ON-DISK SLIDING TRIBOMETER

摘要

A variable loading wear and friction monitor (VLWAFM) pin-on-disk tribometer is disclosed. The VLWAFM pin-on-disk tribometer includes a spindle assembly, a loading lever assembly and a variable loading assembly. The variable loading assembly includes a transmission mechanism, at least one radial disc cam and a follower assembly. The follower assembly includes a flat faced follower, an adjustable lock nut, a helical compression spring and a spring housing. The spring housing is disposed over a loading lever of the loading lever assembly for transmitting variable load from the variable loading assembly to a specimen. The specimen exerts variable load on a rotating wear disc for facilitating measurement of tribological parameters between the specimen and the rotating wear disc under variable loading conditions.
