摘要： Techniques are directed to utilizing a break-in assembly to break-in a gear box. The break-in assembly includes a gear box support to support the gear box. The break-in assembly further includes a drive apparatus coupled with the gear box support, the drive apparatus being constructed and arranged to drive the gear box while the gear box is supported by the gear box support. The break-in assembly further includes a loading apparatus disposed in a fixed position relative to the gear box support, the loading apparatus being constructed and arranged to apply loading to the gear box while the drive apparatus drives the gear box. Accordingly, the gear box may be installed on the break-in assembly, broken in during a gear box break-in period while the gear box is installed on the break-in assembly, removed from the break-in assembly, and installed on a water vessel.

摘要： A method for determining an operating condition of at least one plain bearing includes measuring, by a sensor, structure-borne noise arising from a toothed engagement of a first gear and a second gear, wherein the first gear is rotatably mounted via the plain bearing and meshes with the second gear. The method further includes assigning, to a signal of the sensor, a variable that correlates with the operating condition of the plain bearing.

摘要： The disclosure relates to a method for identifying a change in the operating behavior of a crankshaft drive of a motor vehicle. In particular, the disclosure relates to a method for identifying error states of a torsional-vibration damper in the crankshaft drive, such as a jamming or slipping of a secondary mass of the torsional-vibration damper. The crankshaft drive comprises a crankshaft, a pulse generator that rotates when the crankshaft is in operation and a fixed sensor device, which generates a rotational speed signal N as a function of the rotational speed of the pulse generator. The method comprises the following steps: detecting a current rotational speed signal Nakt of the sensor device during operation of the crankshaft drive; filtering the current rotational speed signal Nakt using a bandpass filter that has at least one first passband range D1 comprising a first center frequency f1; comparing the filtered current rotational speed signal Nakt with a reference signal Nref stored in a memory; and identifying a change in the operating behavior of the crankshaft drive on the basis of the comparison of the filtered current rotational speed signal Nakt with the reference signal Nref. The disclosure further relates to a vehicle, such as a commercial vehicle, having a control device which is configured to perform a method of this kind.

摘要： A failure diagnosing device diagnoses failure of a plurality of reduction gears of a mechanical apparatus which includes a plurality of operation parts, a plurality of motors, and the plurality of reduction gears. The failure diagnosing device includes an acceleration/deceleration period identifying module configured to identify an acceleration/deceleration period of operation of one of the plurality of operation parts, a motor current processing module configured to acquire a peak value of an amplitude of a frequency component of motor current in a specific frequency band of one motor that drives the one operation part, in the acceleration/deceleration period, and a determining module configured to determine whether a sign of failure exists in one of the reduction gears.

摘要： The invention relates to a system for determining a torque applied between two rotating members. The system includes a test body with a deformable structure arranged to transmit the torque while enabling an angular displacement according to the applied torque. The system includes two encoders each on a different rotating member and each capable of emitting a periodic signal representative of the rotational displacement of the corresponding member.

摘要： A method for plausibilizing a sensor signal of a single-track vehicle. The method includes: estimating gear ratios between a wheel speed of a wheel and a pedaling frequency of a pedal of a pedal unit and/or a drive speed of a drive of the single-track vehicle at multiple points in time; ascertaining a value of a reliability indicator based on the estimated gear ratios, the value of the reliability indicator being ascertained with the aid of a statistical parameter, in particular a variance, of the estimated gear ratios and/or a histogram of the estimated gear ratios; and plausibilizing the sensor signal based on a comparison of the value of the reliability indicator with a threshold value, the threshold value corresponding to a maximally permissible value of the reliability indicator.

摘要： A toothing test stand includes a sample holder and a load generator. The load generator has at least one head, and the sample holder is designed to hold at least one part of a single tooth sample separated from toothing of a gear wheel. The tooth sample comprises a tooth of the gear wheel, and the head of the load generator bears against a flank of the tooth and applies a load to the flank. The head of the load generator is rotatably mounted, and an axis of rotation of the head of the load generator, starting from a course that runs parallel to a flank line of the flank of the tooth, rotates about a surface normal of a contact surface of the head of the load generator and the flank of the tooth.
