The basic SRV®5 rotation system

for many test scenarios

With the basic SRV5® rotation system, we offer tribometers for applications that require continuous sliding movement. This tribometric drive and measuring system provides extensive simulation potential.

Its mechanism for developing application-specific test contacts is enormously flexible.
The basic rotation block can accommodate the most diverse test geometries. You can use the basic rotation system to test a wide range of model and component tests, such as integrating a heatable adapter for a pin-on-disk contact, an adapter for transmission hydraulic oils or an adapter for component applications.

  • Suitable for continuous sliding movement
  • Extensive simulation potential
  • Wide range of model and component tests

Test principle of the rotation option

The main components of the rotation module are the basic rotation block, the rotation motor, the motor for the displacement of the block (y-axis) as well as the multi-channel sensor for measuring frictional torque and friction force.

The basic motion in rotation mode runs at a constant speed. The form of motion (sliding or rolling) is determined by the test body pairing. The sliding velocity is a result of the speed of the drive and the displacement of the y-axis.

The opposing body (e.g. pin/ball/disk) is incorporated in the existing test force system with an adapter. The tribo-relevant variables friction torque and friction force are measured on the multi-channel sensors.

Key data of the rotation module

The SRV® rotation module can perform an enormous variety of simulations, measurements and tests as well as tribological analyses. The base plate of the basic block has a diameter of 130 mm, which provides space for numerous geometries. You can perform tests with or without an intermediate medium. Due to the high sliding speeds of 10 m/s and the excellent drive dynamics, you can map friction conditions in your design ranging from boundary friction to hydrodynamics.

Surface pressures of from 0.01 to 5000 MPa can be configured for your specific test projects. Sliding speeds of up to 10 m/s can be achieved in the test contact. The operating temperatures of the friction contact can be adjusted from room temperature to 250°C. Depending upon the expected frictional torque level, you can choose between two measuring ranges, 5 Nm or 40 Nm.

Rotation module functionality

  • Movement type
    The rotation module enables continuous or discontinuous rotary motion at sliding speeds of up to 15 m/s. Based on the rotary motion, two further types of movement are available:
    • Reversing, i.e. oscillating movements can be executed. These are periodically repeated back-and-forth movements. In addition, fixed or wandering endpoints can be set.
    • By displacing the entire rotation mechanism, the test contact can be moved along the y-axis.
  • Contact geometries
    Friction contacts with abstracted contact geometries and a wide range of application-specific contact geometries can be implemented. For the latter, your original parts can be integrated without time-consuming preparation. Many standard test bodies in quality-assured SRV® quality are available.
  • Optional combination with the rotation drive (Combi Drive)
    The rotation and oscillation drives as well as their measurement sensors can be combined. This results in a wealth of simulation options.
