STT - Shaft Twist Tester

Twist test without thread & profilometer

In order to avoid a leak in a radial shaft seal, the sealing surface of the shaft must be made twist-free. Through the optical diffraction, twist structures can be made visible, the amplitudes of which are well below the roughness amplitudes of the sealing surface. Quality control in the immediate vicinity of the machining process can thus be carried out quickly and reliably. With test times in the range of seconds, the devices can be used in a variety of ways, e.g. for incoming inspection, for process optimization of the manufacturing process or for 100% (quality) control in series production.

Application background

Measurement methods & advantages

The sealing function of a shaft seal is largely determined by the twist. As soon as there is a twist, a critical micro-pumping effect begins with the rotation of the shaft, which causes the liquid to escape or wear on the component. These twist structures can be precisely visualized with the Shaft Twist Tester. Optical filtering shows the presence of twist on the test object surface and enables the twist parameters to twist depth and period length to be estimated. The number and brightness of diffraction lines shown is a measure of the twisted depth, their distance a measure of the period length.

Measurement method

The mapping of twist structures was previously only possible with very complex and cost-intensive tactile form measurement technology. A production-related test could not be carried out due to the long measuring time and the restrictive measuring conditions. Alternatively, the thread method is used, which however depends on various boundary conditions (e.g. thread material, thread thickness, attached weight or viscosity of the lubricant). The main disadvantage of this method, however, is that the process demonstrably fails with very small or very large twist structures.




Advantages of the STT-shaft twist tester

As standard, twist is currently tested using the thread method or a profilometric measuring device. Both methods are not suitable for quick use in the production process or 100% control. With the STT, a test device has been developed that meets these requirements and combines reliable testing for freedom from twist with high user-friendliness. The STT hand-held device is placed on the test item. The inspector can immediately recognize the presence of twist structures on the surface of the manufactured component using a system of strips in the field of vision.
