Low Temperature Torque Test Apparatus
Refrigerated two unit apparatus for ASTM low temperature torque tests on
lubricating greases. Includes an insulated, thermostatically controlled air
chamber with test rigs, drive shafts and externally mounted gear motors.
Rotates drive shafts at 1rpm while electronic load cell-strain gauge
indicators measure the torque required to restrain the test rigs. Digital LED
displays indicate torque for each drive unit and cold chamber temperature. On
ASTM D4693 models, spindle temperature is also indicated for each drive unit.
An optional factory installed strip chart recorder provides a hard copy
record of starting torque, running torque and maximum torque. Includes drive
shaft overtorque protection—when drive shaft torque exceeds a preset value,
the drive motors automatically shut down to prevent breakage of shaft
insulators. Standard cooling range of –65°F (–54°C) meets ASTM requirements
for D1478 and D4693 test methods. Optional –100°F (–73°C) range is available
for special testing requirements.
ASTM D1478 Model for Ball Bearing Greases – Equipped with two test
cages and two 6204 ball bearings per ASTM D1478 specifications.
ASTM D4693 Model for Automotive Wheel Bearing Greases – Equipped with
two spring loaded spindle-bearings-hub assemblies, bearing packer assembly
and bearing installation and removal tools.
Combined ASTM D1478-D4693 Model – Equipped with one test cage and one
6204 ball bearing for ASTM D1478 testing and one spindle-bearings-hub
assembly with bearing packer and tools for ASTM D4693 testing.
Data acquisition software – Data acquisition software facilitates
running both ASTM D1478 and D4693 tests. Graph of torque versus time details
starting torque, running torque and time elapsed. Includes software, data
acquisition board and cable.
