Detailed Description
The embodiment of the invention provides a rotor anti-icing cable guide mechanism which comprises a large ring 1, a small ring 2, a large ring lug 3, a small ring lug 4, a connecting rib 5 and a connecting hole 6 as shown in figures 1 and 2. The large ring is sleeved on the propeller hub support arm to realize that the rotor anti-icing cable guide mechanism takes root on the propeller hub support arm; the cable passes through the small circle, and the cable fixing function is realized. When the hub is installed, the fastening piece fastens the large ring lug 3, the small ring lug 4 and the connecting rib 5 through the connecting hole 6, and then the large ring is clamped and fixed on the supporting arm of the hub; the small ring is clamped tightly to firmly fix the cable. Thereby securing the cable to the hub arm.
Wherein, the big ring 1 is sleeved on the supporting arm of the propeller hub to play a role in fixing and supporting the whole mechanism. The diameter D can be adjusted according to the thickness of the supporting arm of the propeller hub;
the small ring 2 is used for fixing the cable. The diameter D1 can be adjusted according to the diameter of the cable;
