Description

Technical Field

[0001] The invention relates to the field of transmission shafts, in particular to a high-speed slip ring rotating hexagonal transmission shaft and a transmission assembly component thereof. Background Art

[0002] Rotary hexagonal transmission is mainly used in the test connection of an aircraft engine. The aircraft engine is the heart of the aircraft, and the blades are one of the most critical parts.

[0003] In the prior art, one end of the rotating hexagonal transmission is connected to the active rotating shaft (engine blade rotating shaft), and the other end is rotationally connected to the driven rotating shaft (high-speed slip ring rotating shaft). Through high-speed rotation, considering that it is difficult to ensure that the two shafts are concentric, it is ensured that the relative position of the angle between the two shafts changes within a certain range, and power can be transmitted reliably and stably.

[0004] However, when testing the high-speed slip ring, the ordinary hexagonal transmission shaft is made of hard aluminum alloy or stainless steel, has no curved surface, and is a hexagonal straight surface, which cannot reduce the coaxiality requirements of the active shaft and the passive shaft. When the active transmission shaft and the driven transmission shaft are directly connected to the ordinary hexagonal transmission shaft, the two shafts are connected through various mounting tables, fixtures, and locking components. The machining errors of the parts and the installation errors caused by the experience during installation are accumulated and superimposed. The coaxiality between the two shafts is very poor. When rotating at high speed, the ordinary regular hexagonal transmission shaft forms a force on the active shaft and the driven shaft, resulting in huge deformation and heat, which can cause serious damage to the two shafts in severe cases.
