Embodiment 1

[0038] Example 1, such as Figure 1-3 As shown, a running-in test and torque testing device of a rotor transmission system according to an embodiment of the present invention includes: a torque tooling bench, a torque load truss 200 and a transmission system under test 300, and the torque tooling bench is used for testing the transmission system The running-in test of 300 provides output power, the torque load truss 200 is used to apply load for the torque test of the transmission system 300 under test, and guides the direction of load application and the weight of the load, and the transmission system 300 under test is used for receiving torque in the run-in test The output power of the tooling bench, and the applied load of the torque load truss 200 in the torque test.

[0039] The torque tooling bench includes a base 101, a fixed assembly installed on the base 101, a stepless speed regulation motor 108 installed on the base 101, a motor driver 109 connected to the stepless ...

Embodiment 2

[0045] Embodiment 2, a running-in test and torque test method of a rotor drive system, based on the run-in test and torque test device of the rotor drive system described in embodiment 1, the method comprises:

[0046] Fix the rotor drive system 301 under test on the fixed assembly, and connect with the stepless speed regulation motor 108 on the base 101 through the clutch device 105;

[0047] The motor driver 109 adjusts the set speed and running time, drives the infinitely variable speed motor 108 to rotate, and starts the running-in test;

[0048] The output power of the infinitely variable speed motor 108 is transmitted to the tested rotor transmission system 301 after the clutch device 105, and the tested rotor transmission system 301 performs running-in operation;

[0049] After the set running time ends, the running-in test ends, the clutch device 105 is disconnected from the tested rotor drive system 301, and the stability and reliability of the tested rotor drive syst...

Abstract

The invention discloses a running-in test and torque test device for a rotor transmission system, comprising: a torque tooling bench, which comprises a base, a fixed component mounted on the base, a stepless speed regulating motor, and a stepless speed regulating motor connected with the stepless speed regulating motor. Motor driver, clutch device mounted between the stepless speed regulating motor and the rotor drive system under test, and a locking device mounted on the base and positioned on the axis of the power shaft of the rotor drive system under test; torque load truss, which includes profiles The truss and the weights mounted on the profile truss; the tested transmission system, which includes the tested rotor transmission system mounted on the fixed component and the two torsion arms fixed with the rotor hub of the tested rotor transmission system, one torsion arm and the The weights are fixed and the other torsion arm is fixed in the opposite direction to the profile truss. The invention also provides a method for running-in test and torque test of the rotor drive system. The beneficial effects of the invention are as follows: it is convenient to find defects such as the reliability of the rotor drive system in time.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a running-in test and torque test device and method for a rotor drive system. Background technique [0002] With the increasing role and status of helicopters in modern warfare and national economic construction, helicopters have attracted more and more attention from industrialized countries, especially the reliability and safety of helicopters. Maintainability and supportability are key characteristics that affect helicopter combat effectiveness, operational suitability and life cycle cost. [0003] Reliability is generated at an early design stage. However, this reliability can only be achieved through a process of experimental analysis and modification. Design tools will provide valuable insights into reliability characteristics, but there will still be completely unpredictable or only Various problems that can be exposed through experiments can only be gradua...
