Abstract

[0001] The utility model relates to the field of steering gear detection, in particular to a steering gear output torque detection device. Background Art
[0002] The servo is an essential part of the aircraft. Its function is to achieve attitude control of the aircraft by outputting torque to the rudder blades and overcome the complex air resistance encountered during flight. Therefore, the servo needs to be able to output and withstand sufficient torque. Therefore, the servo needs to undergo necessary torque testing before installation. The patent with application number 201811245135.9 proposes a comprehensive test platform for the dynamic performance of aircraft servos, which is used to detect multiple performances of servos. It has complete functions but a relatively complex structure. The patent with application number 202223274061.6 generates additional torque by setting a servo motor and loads it to the servo, thereby judging the output and tolerable torque of the servo. The structure is simple, but the torque generated by the servo motor is an active additional torque. When this torque is too large, it is easy to cause damage to the servo itself.
[0003] The utility model provides a steering gear output torque detection device, which determines the magnitude of the steering gear output torque by generating passive braking torque through a magnetic powder brake, has a simple structure, is easy to operate, and is safe and reliable.

[0015] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.
[0016] like Figure 1As shown, a servo output torque detection device comprises a base 1, a magnetic powder brake 2, a digital display tension controller 3, an elastic coupling 4, a servo to be tested 5, a fixed bracket 6 and an adjustment pad 7. The magnetic powder brake 2 is fixed to the base 1 by standard bolts, the servo to be tested 5 and the magnetic powder brake 2 are directly connected by the elastic coupling 4, the servo to be tested 5 is placed on the fixed bracket 6 and connected by standard bolts, the fixed bracket 6 is connected to the base 1 by standard bolts, and an adjustment pad 7 is arranged between the fixed bracket 6 and the base 1. The base 1 is a standard T-slot structure base; the magnetic powder brake 2, the digital display tension controller 3 and the elastic coupling 4 are all standard components; vertical waist-shaped through holes are arranged at both ends of the lower plane of the fixed bracket 6, and horizontal waist-shaped through holes are arranged on the upper plane; the adjustment pad 7 is a rectangular standard height block. The lateral and vertical positions of the servo motor 5 to be tested are adjusted by the waist-shaped through holes on the fixing bracket 6, and the height of the servo motor 5 to be tested is adjusted by adjusting the adjusting pads 7 of different thicknesses, so that the output shaft center line of the servo motor 5 to be tested and the shaft center line of the magnetic powder brake 2 are in the same straight line.
[0017] When in use, the servo motor 5 to be tested is started, and the output torque is transmitted to the magnetic powder brake 2 through the elastic coupling 4. At the same time, the braking torque of the magnetic powder brake 2 is gradually increased from small to large through the digital tension controller 3. Initially, the braking torque generated by the magnetic powder brake 2 is small, and the output shaft of the servo motor 5 to be tested will keep rotating. When the torque generated by the magnetic powder brake 2 gradually increases, the speed of the output shaft of the servo motor 5 to be tested will gradually slow down until the torque generated by the magnetic powder brake 2 is equal to the output torque of the servo motor 5 to be tested, and the output shaft of the servo motor 5 to be tested stops rotating. At this time, the displayed value read by the digital tension controller 3 is the torque value output by the servo motor.
