Concept- Interchangeable modules on same platform
The tribometer has a modular architecture. Easy to change modules allows it to run practically any friction test, wear test. The platform comes with lower X,Y and and upper Multiple Z stages. On top of XY stage various modules mount. Flow chart about configuring
● Rotary – Pin on disk tribometer, ball on disk tribometer etc. 0.001-10,000 RPM
● Reciprocating – Linear reciprocating tribometer wear, pin on plate etc. up to 80Hz
● Block on Ring – Test bearings, shafts, lubricant, grease, etc. high torque, high speed
● Upper Rotation – 4 Ball tester, tapping torque tester, seals etc. upto 5000RPM
● Long Stroke High Speed- 40mm at 40Hz. test piston ring cylinder liner, engines, compressors etc.
● Fretting Voice Coil – 5um to 4mm stroke, upto 500Hz. Fretting wear, fretting loop creation
Patented Integrated Inline 3D Profilometer
Rtec friction tester comes with inline integrated 3d profilometer to create surface imaging. This allows to study surface change vs time with nm resolution. Why friction force changes can be easily quantified. Various techniques such as interferometer, confocal , raman are available for the measurements. The tester allows for automatic stitching across a large surface area for volume wear, roughness calculations.
Rigid tribometer design allows for a very low floor noise, that enables to perform 3D images automatically. The optical profilometery was specifically optimized to work on tribology wear marks as they typically have steep slopes, dark texture, liquid layers on top. There are two optical heads available for integration.
● Sigma head – White light interferometery
● Lambda Head – White light interferometery + Confocal microscopy + Dark Field + Bright Field Imaging
Automatic Sub nm Surface Change Image vs Time
The data shows 3D wear mark progression during linear reciprocating test. The data is then used to calculate and study
● Volume wear progression
● Roughness change
● Crack initiation and propagation
● Debris creation
● Topography change
● Effect of textures on tribology
● Effect of surface roughness
The profilometer images can be taken vs time, cycles or on a trigger, for eg. image the wear track when acoustic emission channel shows crack initiation point or when there is sudden change in friction etc.
Unmatched Load Cell Technology – Capacitive, Piezo
The universal mechanical tester has a wide range of patented load cell technology. The offered sensor resolution, negligible drift is unparalleled today. The wide load range extends from nN to 12,000N using fast exchange The sensors comes with various forms 1D, 2D, 6D,
● Capacitive Load Cells – Highest resolution load cells with neglibile thermal drifts.
● Piezo Load Cells – Sensors to measure data at highest frequencies.
● Strain Gauge Load Cells – Sensor with widest load range.
● Dynamic torque Sensors – Sensors to measure inline torque during rotating motions.
Other Important Features
Environmental Chambers– Results from friction and wear testers depends a lot on environment it was tested on. The high temperature tribometer module has a wide operating range -120C to 1200C, inert gas, humidity, vacuum , pressure, tribocorrosion etc
Custom Motion -Standard configuration has X,Y,Z plus an add on interchangeable motion axis drive. This unique multi axis drive combination allows to create any custom motion to simulate testing conditions close to real life scenario.
Precision and repeatability – The tester comes floor standing or in bench top models. The rigid frame construction, low floor noise, advanced electronics allows the tester to deliver high precision and repeatability across wide range of applications.
Application specific solution Rtec Tribometer versatility and modular construction allows it to provide several tribological and mechanical testing solution for various industries. Today its widely used to measure friction coefficient lubricant, grease, bio, automobile, aerospace, materials, ceramics, space industries etc. To get correct coefficient of friction, wear volume it is important that tests be done in conditions that is close to real application. Using custom motions, wide load range, customizable holders and drives the tribometer allows to generate meaningful data with ease.
