High Temperature Wheel Bearing Grease Tester

Description

As per ASTM D3527 ,D4290, D4950. The equipment is used for testing of grease for evaluating its life performance by testing at high-temperature. The equipment consists of a modified front wheel hub-spindle-bearings assembly housed in a constant temperature oven and coupled to a ¼ Hp variable-speed drive motor. It Control the test functions automatically and provides continuous digital display of motor torque, rpm, chamber temperature, spindle temperature, time cycle and elapsed time. Test parameters outside of ASTM specifications can be selected by the operator for in-house testing. Automatically terminates test and displays elapsed on-cycle hours when grease deterioration causes drive motor torque to increase to the calibrated end point. A built-in thirty second time delay circuit prevents erroneous test terminations due to momentary surges in motor torque at the beginning of the on-cycle. Insulated constant temperature oven is equipped with a 1200W heater and balanced 1/20 hp circulation fan for efficient heat distribution. Sliding access doors and a movable platform that swings the drive motor out of the way provide easy access to the spindle assembly. Modified steel spindle and hub assembly conforms to all critical 1971 Chevy II dimensions and is fitted with thermocouple, bearing thrust loading device and anodized aluminum grease collector. All controls and monitors are housed in a separate cabinet. Digital controls and displays: Timer : on/off cycle and real time Motor rpm : 0-1725 rpm Motor Torque: current draw Elapsed Time: 9999.9 hr.
