Tribometer UTM100


  • Tribological testing in rotational movements

The tribometer is used for examining and simulating friction and abrasion processes under rolling and 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.

In the standard testing procedure a half bearing is pressed against a rotating shaft with a defined normal force. Both specimen are arranged vertically, the rotating shaft being positioned below. The normal force is applied by a motor spindle system. The drive unit is a servomotor which can be regulated continuously variably between 0.1 and 6000min-1. The actual testing device consists of the motor unit, the drive unit and the load component. During the testing a continuous measuring of the normal force, the linear distance of both friction materials, the rotational speeds and the friction torque takes place. The temperature is measured and controlled by a type K thermocouple in the oil reservoir. The active torque is registered by a torque shaft and the reactive torque by a frictional force sensor. 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.
