Gearbox for industrial applications or wind power plants

A gearbox for industrial application or a wind power plant, comprising:

• a gearbox housing having a housing cover;
• at least one drive shaft configured to pass through a first opening of the gearbox housing;
• at least one output shaft configured to pass through a second opening of the gearbox housing;
• first and second gearwheels connected to the drive shaft and the output shaft, respectively, and engaging indirectly or directly with one another;
• at least one sensing device configured to detect a torque acting on the drive shaft, the output shaft or a shaft driveable by the drive shaft;
• an energy-generating device connected electrically to the at least one sensing device;
• a rotor operatively connected to the energy-generating device and arranged within the gearbox housing and enclosed by the housing cover, said rotor being connected in fixed rotative engagement to a member, which is in driving relationship with the drive shaft and selected from the group consisting of the output shaft and the shaft driveable by the drive shaft;
• a bearing configured to support the member and secured by the housing cover;
• a stator operatively connected to the energy-generating device and mounted on the housing cover within the gearbox housing, with an air gap being formed between the rotor and the stator;
• and an evaluation device connected to the at least one sensing device for detecting a load spectrum.
