Abstract
The application provides a reversing air-operated direct-drive through-shaft power take-off, which is used for solving the problems of complex structure, large overall size and numerous parts of the current air-operated power take-off. The application comprises a power take-off shell, an input shaft, an output shaft and a shift fork shaft and a driving module arranged in the power take-off shell. The front end of the input shaft is connected with an external power device through the power take-off shell, the rear end of the input shaft is located in the power take-off shell and connected with the power take-off shell through a first bearing. A blind hole is arranged in the end face of the input shaft, the front end of the output shaft is arranged in the blind hole through a third bearing. The end of the output shaft passes through the power take-off shell. The output shaft and the input shaft are coaxially arranged. The front end of the output shaft is sleeved with a sliding sleeve, the outer side of the sliding sleeve is provided with a guide block, one end of the shift fork shaft is connected with the guide block through a connecting rod, the driving end of the driving module is connected with the other end of the shift fork shaft. The rear section of the output shaft is arranged on the power take-off shell through a second bearing.
