Intelligent filtering and driving device

Abstract

The invention discloses an intelligent filtering and driving device which comprises a filtering reducer assembly, a servo motor and an acceleration / speed / temperature sensor. The intelligent filtering and driving device integrates the filtering reducer assembly, the servo motor and the sensor, thus effectively simplifying the structure, reducing the volume and mass of the device, and improving the system precision. Through a controllable interface, a filtering gear can generate elastic deformation so as to effectively prevent nonlinear coupling vibration generated by influence of extreme working conditions and special environment, avoid the problems of reliability such as non-smooth work, even blockage and the like, guarantee a driving piece to work within the designed range of driving precision and bearing capacity, control the fluctuation generated by the motor due to the change from a high-speed small torque to a low-speed large torque, and reduce vibration noise and fatigue wear. The sensor and the driving part are integrated, so that the running state of the device can be detected in real time, failure signals can be extracted, and the failure can be estimated and predicted so as to guarantee the reliability of the device.

Problems solved by technology

For a long time, the drive motor and reducer in mechanical equipment have been designed separately, so it is inevitable to consider the connection design between them, and use keys, couplings and other connection devices, which makes the structure more complicated and the number of parts increases. , the reliability of the system is reduced, the volume and weight are increased, and the shaft alignment error is caused, which leads to wear of the transmission mechanism, and the mechanism is prone to jamming during operation

On the other hand, as the power source of the transmission system, the form of the mechanical energy generated by the motor changes accordingly, from high speed and low torque at the input end to high torque and low speed at the output end, which inevitably leads to the rotation of the transmission system. Torque fluctuations; the manufacturing and assembly errors of each part; the impact of meshing and meshing when the teeth mesh; and the loss of parts during operation. These factors will increase the vibration and noise during the operation of the transmission mechanism and affect the gears. Especially in extreme working conditions and special environments such as high and low temperature alternating, vibration and shock, due to the thermal deformation of the gear material and the coupling vibration with the external environment, the interference of the tooth profile will be caused, which will aggravate the wear and fatigue of the tooth surface, and even the gear The "jamming" or even "jamming" phenomenon between the tooth and the tooth seriously affects the reliability of the gear transmission
