  • Method for determining bearing play of exhaust-gas-turbocharger friction bearings
    Patent number: 10119419
    Abstract: The invention relates to a method for determining bearing play of exhaust-gas-turbocharger friction bearings comprising the following method steps: accelerating the exhaust-gas turbocharger or the body group from standstill to a maximum rotational speed and at the same time registering the vibration acceleration by means of a sensor; determining the constant-tone frequency of the friction bearing at at least one rotational speed; plotting the determined constant-tone frequency in a diagram, in which bearing-play ranges determined experimentally in advance are assigned to constant-tone frequency ranges; and establishing whether or not the determined constant-tone frequency lies in a bearing-play target range.
