Abstract

The invention discloses an oil-drive coupling delivering and connecting mechanism and relates to a delivering and connecting mechanism delivering liquid and transmitting torque. The oil-drive coupling delivering and connecting mechanism is capable of transmitting torque and delivering liquid in two directions, simple to assembly and reliable in transmission and has high sealing performance and economic efficiency. An input shaft and an output shaft are provided with through holes for delivering oil along the axial direction in the middle and are coaxially arranged, projections or grooves on the end face of the input shaft are in close fit to the grooves or projections of the output shaft, and annular sealing parts are fixedly mounted in annular sealing grooves of the outer circumferences of the input shaft and the output shaft. A connecting casing is tightly sleeved with the joint of the input shaft and the output shaft, elastic shaft retainer rings are fixedly mounted in the annular grooves of the outer circumferences of the input shaft and the output shaft, and the connecting casing is axially limited by the elastic shaft retainer rings. The connecting casing is sealed with the input shaft and the output shaft through the annular sealing parts. The oil-drive coupling delivering and connecting mechanism can be used for an occasion that two hollow semi-shafts used for transmitting torque and delivering liquid are needed to be in shaft connection.

Description

technical field [0001] The invention relates to a transmission connection mechanism for simultaneously transmitting liquid and torque. Background technique [0002] For the situation where two shafts need to transmit torque and liquid at the same time, such as two shafts that need to transmit lubricating oil and torque at the same time, in order to realize the above-mentioned specific transmission function, when connecting and assembling the two shafts, it is necessary to consider assembly and smooth transmission Performance, tightness and economy. Traditional solutions include flange connection, spline connection, pipe thread and other connection methods, but flange connection has a complex structure, requires a large space, and has limited application range; spline connection is complicated to process and difficult to ensure sealing; and pipe The threaded connection can only transmit a small torque in one direction, which is difficult to meet the requirements of use.
