Embodiment Construction
[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.
[0036] like Figure 1 to Figure 5 As shown, the preferred embodiment of the present invention provides a tool for functional inspection of the propeller speed regulating mechanism, which is used to check whether the propeller speed regulating mechanism can meet the forward propeller function requirements and reverse propeller function requirements of the test run stage at the ground stage, without The forward propeller function and reverse propeller function of the propeller speed regulating mechanism can be checked by installing the engine on the test bench, which is conducive to earlier detection of faults and repairs of the propeller speed regulating mechanism, and reduces the inspection workload in the test run stage. The tooling for functional inspection of t...

The invention discloses a tool and a method for checking the function of a propeller speed regulating mechanism. In the tooling and method of the present invention, the angle measuring disk is fixed on the propeller speed regulating mechanism, and the 360° scale line on the angle measuring disk is used as the angle measurement reference, and the hand-held torque wrench rotates to drive the connecting rod mechanism to rotate, thereby the connecting rod mechanism is rotated. Check the movement stroke of the rod mechanism, and determine the angle of rotation by rotating the pointer on the curved rod relative to the position of the 360° scale line. When turning clockwise to the 62° position, check whether the pointer of the fuel adjustment power indicator of the engine is When it reaches 90°, when it is rotated counterclockwise to 44°, check whether the pointer of the fuel control power indicator of the engine reaches above 80°, then the forward propeller function check and reverse propeller function check of the propeller speed regulating mechanism can be completed without turning the The engine is installed on the test frame for inspection, which is conducive to early discovery of the failure of the propeller speed regulating mechanism and repairs, reducing the test run.
Description
technical field [0001] The invention relates to the technical field of propeller testing, in particular to a tool for functional inspection of a propeller speed regulating mechanism, and also relates to a method for using the tooling to perform functional inspection of a propeller speed regulating mechanism. Background technique [0002] Before the test run of the turboprop engine bench, it is necessary to adjust the propeller speed control system in the state of loading on the ground to check whether it can meet the maximum forward propeller function and the maximum reverse propeller function during the test run. And because the propeller speed regulating mechanism system of this type of engine is complicated, it is made up of a whole set of cam spring linkage mechanism, and the adjustment part is only a short spline shaft, which cannot be rotated flexibly without the aid of tools. [0003] At present, there is no reliable means of adjusting the propeller speed regulating m...
