Abstract
The invention relates to a method for eliminating regular polygon chain vibration in a chain conveyor, wherein the chain conveyor comprises a motor, an input shaft, an output shaft, a regular polygon chain wheel, a chain and an anti-vibration transmission structure, the motor is in transmission connection with the input shaft, the input shaft is in transmission connection with the output shaft through the anti-vibration transmission structure, the output shaft is in rotation connection with the regular polygon chain wheel, the regular polygon chain wheel drives the chain, and the anti-vibration transmission structure is used for eliminating vibration generated on the chain in the rotation process of the regular polygon chain wheel. Since the eccentric is pressed against the fixed wheel, the wobble carrier oscillates periodically with the rotation of the eccentric, so that fluctuations in speed occur. The anti-vibration transmission structure transmits the speed fluctuation to the regular polygon chain wheel and keeps synchronous with the fluctuation of the chain, so that the vibration of the chain generated by the transmission of the regular polygon chain wheel is stabilized.
