Background:
The TE 53SLIM Multi-Purpose Friction and Wear Tester is a versatile machine offering uni-directional sliding tests in block on ring configuration and combined rolling/sliding tests in two roller configuration. The machine was developed under a licence from the United Kingdom National Centre of Tribology. The control unit includes the SLIM 2000 Serial Link Interface Module and COMPEND 2000 Windows Based control and data acquisition software. Tests may be run according to procedures described under ASTM G 77 and ISO/DIS 7148-2.
Description:
A bearing housing carries two parallel shafts. The lower shaft carries a flat profile ring or roller and is connected to an ac geared motor with frequency inverter variable speed drive.
In block on ring configuration the upper shaft carries a holder for the fixed specimen and is restrained from rotating. The specimen may be a ball (ball on cylinder test), a block (block on ring test ) or a cylinder (crossed cylinder test). A holder for blocks described in ASTM G 77 test may also be provided.
In two roller configuration the upper shaft carries a crowned profile roller and is driven from the lower shaft through a pair of gears. Seven fixed amounts of percentage slip are provided.
The upper shaft is carried in a spherical bearing at one end that permits rotation about the gear contact line and has a floating bearing at the other end. This allow the shaft to pivot freely in the vertical and horizontal axes. Load is applied by dead weights through a 5:1 lever and acts on the front end of the shaft by pressing on the outer race of the floating bearing.
Horizontal movement in the direction perpendicular to the upper shaft axis and is resisted by a strain gauge transducer. This gives measurements of the tangential forces in the contact which are displayed as friction force on the control unit.
In block on ring configuration an LVDT transducer is provided to measure the movement of the upper shaft as the specimen wears away. This displacement measurement is used to determine steady-state wear and wear transitions. It should always be compared with weight loss or dimensional changes for accurate wear assessment due to the effects of thermal expansion in the contact.
Lubricant can be introduced by drip feed or by running the lower roller in a small temperature controlled reservoir.
Roller and block specimens can be manufactured easily from a variety of materials including metals, plastics, elastomers and ceramics.
Control and Data Acquisition:
The TE 53SLIM has PC based sequence control and data acquisition features. This is provided by an integrated SLIM 2000 Serial Link Interface Module and COMPEND 2000 software running on a host PC.
The COMPEND 2000 software is Windows based and Windows 95, 98, NT and Y2K compatible. The software employs Windows “look and feel” features for easy user access to all machine and test set-up parameters. On-screen tool tips are provided.
Data may be stored to hard disc and the software includes an auto-scaling trend display for monitoring test progress. At the end of a test this graph may be dumped to a Windows printer and the stored data may be manipulated for calculation or graphical presentation in standard spreadsheet software programs.
Tests are defined by a sequence of steps, each step containing set-point, data recording rates and alarm level information. Set-points may be adjusted by step change or ramp. The test sequence is followed unless interrupted by the operator or an alarm. Set points may also be adjusted manually during the operation of the test sequence.
