Claims23
A mechanical overload protected drive unit for driving a ring gear connected to a device, comprising
- at least one motor, said motor providing a torque flow,
- at least one transmission connected to the motor, said transmission being driven by the torque flow provided by the motor, and conveying the torque flow to
- at least one output shaft connected to the transmission, said output shaft being driven by the torque flow conveyed by the transmission, and conveying the torque flow to
- at least one pinion connected to the output shaft, said pinion being driven by the torque flow conveyed by the output shaft, wherein said pinion is arranged in direct mechanical contact with the ring gear for driving the ring gear, and
- at least one mechanical overload protection device positioned between the transmission and the pinion, wherein said mechanical overload protection device is arranged to protect the teeth of the ring gear and/or the pinion from overload caused fracture.
A mechanical overload protected device comprising a ring gear, said ring gear being driven by at least one mechanical overload protected drive unit, wherein the at least one drive unit includes
- at least one motor, said motor providing a torque flow,
- at least one transmission connected to the motor, said transmission being driven by the torque flow provided by the motor, and conveying the torque flow to
- at least one output shaft connected to the transmission, said output shaft being driven by the torque flow conveyed by the transmission, and conveying the torque flow to
- at least one pinion connected to the output shaft, said pinion being driven by the torque flow conveyed by the output shaft, wherein said pinion is arranged in direct mechanical contact with the ring gear for driving the ring gear, and
- at least one mechanical overload protection device positioned between the transmission and the pinion, wherein said mechanical overload protection device is arranged to protect the teeth of the ring gear and/or the pinion from overload caused fracture.
