The invention relates to a method for automated detection of at least one damage event in a rolling bearing; comprising the method steps: measuring (101) at least one speed of the bearing rings of the bearing relative to each other; measuring (103) at least one circumferential frequency of a rolling body of the rolling bearing about a rotation axis of the bearing; recording (105) a mechanical oscillation caused by the bearing; and examining (109) the recorded oscillation for the presence of a modification to the oscillation caused by the damage event; wherein the modification of the oscillation by the damage event is determined in consideration of the speed of the inner ring and of the outer ring. The modification of the oscillation caused by the damage event is determined in consideration of the circumferential frequency of the rolling body.
The invention relates to a method and a system for monitoring the condition of a sliding bearing (1) operated with lubricating oil for a rotating component, in which a physical variable characteristic for the bearing is measured using at least one sensor (2), which variable is supplied to a control unit (ECU) for condition monitoring, comprising the following steps: - determining by means of the control unit (ECU) at least one condition variable (s; T; p) of the sliding bearing (1) and/or of the lubricating oil as an output variable (y) from at least one physical sliding bearing model (N-V-F), to which at least the rotational speed (n) and the torque (M) are supplied as input variables (u), and a dynamic behaviour of the lubricating oil is assigned to these input variables (u); - measuring with at least one sensor (2) a comparative value for at least one of the condition variables (s; T; p); - evaluating, from a comparison of the measured value of the condition variable (s; T; p) with the model-based value for the condition variable (s; T; p) computed as output variables (y), to what extend the physical sliding bearing model (N-V-F) maps the real behaviour of the sliding bearing (1).
The invention relates to a planetary gear mechanism stage having a sliding bearing arrangement (10; 10a-10e), in particular for a planetary gear bearing, comprising at least three planetary gear shafts (11), on each of which at least one planetary gear (12) is rotatably mounted by means of the sliding bearing arrangement (10; 10a-10e) which has a bearing bushing unit which is mounted on the respective planetary gear shaft (11) and has the purpose of providing combined axial and radial bearing for the planetary gear (12), wherein the bearing bushing unit comprises a pair of conical bearing rings (100a, 100b - 500a, 500b) which each have a cylindrical inner face (110) and an outer face (120) which runs obliquely with respect to the latter, wherein the inner face (110) comes dressed on the planetary gear shaft (11) or on at least one inner sliding bearing bushing (510a, 510b) which is mounted thereon, and the outer face (120) interacts with a bearing face, shaped so as to correspond to the latter, on the planetary gear (12) for forming a sliding bearing.
The invention relates to a toothed gear wheel comprising at least one tooth flank (101). The length of at least one contact line (111) extending across the tooth flank (101) is longer than the width of said tooth flank (101).
