Abstract

The invention provides a coupling. The coupling comprises a driving installation end connected with a driving shaft, a driven installation end connected with a driven shaft, as well as a connecting part connected with the driving installation end and the driven installation end, wherein the driving installation end and the driven installation end are respectively provided with a spline, and the periphery circle of the connecting part is provided with a spiral through groove. According to the coupling provided by the invention, the driving installation end and the driven installation end are respectively provided with the spline and are connected with the driving shaft and the driven shaft through the splines, thus being convenient and reliable; the periphery circle of the connecting part connecting the driving installation end and the driven installation end is provided with the spiral through groove, so as to enable the coupling to have a certain elasticity, and when the coupling is under certain impact, the coupling has a certain buffering vibration attenuation action; and the coupling with the elasticity can compensate the coaxiality of the driving shaft and the driven shaft, and when the driving shaft and the driven shaft have an eccentricity phenomenon, the coupling is not twisted off right away. The invention also provides a drive gear box.

Description

technical field [0001] The invention relates to the field of transmission gearboxes, in particular to a shaft coupling. In addition, the present invention also relates to a transmission gearbox comprising the above coupling. Background technique [0002] The accessory transmission gearbox is a key component of the aviation auxiliary power unit, and the random accessories of the aviation auxiliary power unit such as the starter, the lubricating oil pump, and the fuel pump usually use the transmission shaft to transmit torque. The traditional torque transmission of the transmission shaft is through setting splines or flat keys on the rigid shaft, and the movement and torque are transmitted through the spline or flat key connection. When subjected to an impact load, the traditional rigid shaft counteracts the impact load by reducing its strength, and the rigid shaft cannot compensate for the coaxiality of the shafts installed at both ends of the rigid shaft. Once the shaft ins...
