Technical Field
The utility model relates to the technical field of helicopter tail rotor electric current collection deflection, in particular to an auxiliary measuring device for helicopter tail rotor electric current collection deflection.
Background
At present, when the helicopter tail rotor electric current collection deflection measurement is carried out, a tail rotor electric current collection device is installed on a tail speed reducer on the ground when the tail speed reducer is not installed, and a deflection measurement base is used for fixing a dial indicator for measurement; if the measurement is not carried out on the ground, the fixed position of the dial indicator cannot be found to carry out the measurement after the tail speed reducer is installed. The current measurement method has the following disadvantages:
1. because the existing detection method uses the deflection measurement base to fix the dial indicator for measurement on the ground, the deflection measurement cannot be carried out when the tail speed reducer is firstly installed on an airplane. Therefore, in the actual process, the two finished products of the tail reducer and the tail rotor electric current collecting device need to be simultaneously assembled, and deflection measurement is firstly carried out after assembly, so that the tail reducer and the tail rotor electric current collecting device can be installed on the airplane. If the tail rotor electric current collecting device (finished product) is lack of parts, the installation process of the tail speed reducer cannot be carried out, and the other processes on a large number of final assembly sites can be influenced.
2. If the rear propeller electric current collecting device needs to perform secondary detection on circular runout after being assembled, the rear reducer needs to be disassembled to the ground for secondary detection, and at the moment, the rear transmission inclined shaft needs to be disassembled; the disassembly and assembly workload is huge.
