Characteristics
- Tribological testing in rotational movements
The tribometer is used for examining and simulating friction and abrasion processes under sliding load.
It can be operated without lubrication with solid objects and with fluid lubricants with boundary or mixed friction. Thus both materials and lubricants can be examined.
During the standard testing procedure a stationary specimen (pin or ball) is pressed against the front surface of a rotating disc with a defined normal force. Both specimen are arranged vertically, the rotating disc being positioned above. Other testing procedures can be conceived as well.
The normal force is provided by the movement of the motor block via a motor spindle system. A spring situated in the sensor block under the linear table is used as absorption of the normal force. The drive unit is a servomotor which can be regulated continuously variably between 0.1 and 3000min-1. The actual testing device consists of the motor unit, the drive unit and the load component. The assemblies are fixed n top of each other in a slideable manner to two vertically positioned bars. During the testing a continuous measuring of the normal force, the ambient temperature in the bowl, the linear distance of both friction materials, the rotational speed and the friction torque takes place. The specimen bowl can be heated between RT and 150°C. A K-type thermocouple in the specimen bowl provides temperature measuring and adjusting. The displacement is measured between lower and upper specimen position. The displacement is measured without contact by an optical laser displacement sensor. The active torque is registered by a torque shaft and the reactive torque is measured by a torque module. All measurement signals are sent to the control cabinet and processed accordingly. The data collection is provided by a multi-functional data collection module with a resolution of 16 Bit and the software provides a measuring frequency of 0.01 – 100 Hz. The rotational speed is registered digitally with a measuring frequency of 4 Hz. The software is used for controlling and measurement data recording purposes.
