Abstract

The invention provides a process for measuring the relative movement of at least two components, such as a fixed wheel, a loose wheel and a sliding sleeve of a synchronizing device. For analyzing the measuring values after the detection thereof, first at least a portion of the measuring values is adjusted by linking them with one another, taking into account known marginal conditions. By means of a subsequent standardization of the series of measuring values, in addition, as required, the reference system (the location of the observer of the measurement), can be freely selected. Thus, it is possible to observe the event from a particularly suitable reference system, such as the synchronizing rotational speed. The joint display of the series of measuring values precisely defines the relative movement of the observed components.

Dependent claims

A process for measuring the relative movement of at least two components, comprising:

detecting series of measuring values of movement of the at least two components;
adjusting at least two series of measuring values by comparing the measuring values at at least one point at which the ratio of the relative movements of the at least two components within the series of measuring values is known as a marginal condition;
calculating a position and the alignment of all components in a reference system while standardizing the series of measuring values;
and
jointly displaying the standardized series of measuring values;
wherein
after an adjustment, the position of the at least two components is computed by determining and integrating speeds of the at least two components;
and
the position of the at least two components is then adjusted at a suitable point in time while using known marginal conditions, relative positions and constructive dimensions.
