Abstract
A computer-implemented method for identifying a gearwheel (5) that induces vibrations in a transmission includes training a generic AI model with a training data set of a group of reference gearwheels (19). At least one reference profile of a surface (21) of the reference gearwheel (19) and a gearwheel category are provided for each reference gearwheel (19) of the group. The method also includes determining a profile of a surface (11) of a gearwheel (5) and assigning one of the gearwheel categories to the gearwheel (5) on the basis of the determined profile by the trained AI model.

A computer-implemented method for identifying a gearwheel (5) that induces vibrations in a transmission, the comprising:
- training a generic Al model with a training data set of a group of reference gearwheels (19), at least one reference profile of a surface (21) and a gearwheel category provided for each reference gearwheel (19) of the group, a first gearwheel category (23) of the gearwheel categories assigned to each reference gearwheel (19) of the group that induces a vibration in the transmission that is equal to a vibration threshold or above the vibration threshold, a second gearwheel category (25) of the gearwheel categories assigned to each reference gearwheel (19) that induces a vibration in the transmission that is below the vibration threshold;
- determining a profile of a surface (11) of a gearwheel (5);
- and
- assigning, by the trained Al model, one of the gearwheel categories to the gearwheel (5) based on the determined profile.
A device for identifying a gearwheel (5) that induces vibrations in a transmission, the device comprising:
- a sensor;
- one or more processors (13);
- and
- one or more non-transitory computer readable storage mediums (15) having stored thereon instructions that, when executed by the one or more processors (13), cause the one or more processors (13) to
- train a generic Al model with a training data set of a group of reference gearwheels (19), at least one reference profile of a surface (21) and a gearwheel category provided for each reference gearwheel (19) of the group, a first gearwheel category (23) of the gearwheel categories assigned to each reference gearwheel (19) of the group that induces a vibration in the transmission that is equal to a vibration threshold or above the vibration threshold, a second gearwheel category (25) of the gearwheel categories assigned to each reference gearwheel (19) that induces a vibration in the transmission that is below the vibration threshold,
- determine a profile of a surface (11) of a gearwheel (5) from the sensor, and
- assign, by the trained Al model, one of the gearwheel categories to the gearwheel (5) based on the determined profile.
