  1. 31. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Ahnesjö; [2020]
    Keywords : Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

    Abstract : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

  4. 33. Prediction of life durability in friction for wet clutches of DCT gearboxes

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Lars-Johan Sandström; [2020]
    Keywords : wet clutch; DCT; Gearbox; Durability; Friction; Life; Dual Clutch Transmission;

    Abstract : Many new cars are equipped with automatic transmissions. These gearboxes often have a dual clutch transmission (DCT) that has a built-in wet clutch. The lubricants used in these gearboxes is often very advanced because it must take care of two systems, the wet clutch and the gears. There is always a strive to make the drain intervals longer.

  6. 35. Planetary Gear Analysis : deformation induced misalignment and optimization

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Jonsson; [2020]
    Keywords : FEM; gears; KISSsoft; misalignment; planetary gears; FEM; KISSsoft; kugghjul; planetväxlar; vinkelfel;

    Abstract : A handheld heavy-duty nut runner, commonly used to assemble windmills and oil pipe lines, and capable of producing 4100 Nm of torque, experiences low cycle fatigue and usually fails after 20 000 cycles at the specified torque. A full assembly Finite element model of the last stage of the four-stage planetary gearbox is constructed and simulated over one complete load cycle. READ MORE
