[0020] 图2示出了本实用新型所提供的装置的工作原理图。 [0020] FIG. 2 shows the operating principle of the apparatus of FIG utility provided by the present novel.

[0021] 本装置的工作原理为: [0021] The working principle of this apparatus is as follows:

[0022] 当螺旋桨发动机12启动时,由于光轴5上固定有直线滑动轴承6,直线滑动轴承6对光轴5起限制作用,使得光轴5只能沿轴向进行水平运动和绕轴向的转动,更进一步地,光轴5位于位置已固定的扭矩传感器2和压力传感器10之间,这使得光轴5仅存在沿水平方向的运动趋势以及绕轴向转动的趋势。 [0022] When the propeller engine 12, since the optical axis 5 is fixed to the linear sliding bearings 6, 6 linear bearings be limiting optical axis 5, such that only horizontal movement axis 5 and axially about the axis rotation, further, the optical axis 5 is fixed at a position of the torque sensor 2 and the pressure sensor 10 between which the optical axis 5 such that the movement trend is present only in the horizontal direction, and axial rotation about the trend.

[0023] 由于固定在发动机安装架8的垂直面板上的螺旋桨发动机12的转动主轴与光轴5平行,且螺旋桨发动机12与光轴5是通过发动机安装架8、第一光轴固定支架4和第二光轴固定支架9固定在一起的,因此,光轴5上的扭矩NI就可表示螺旋桨发动机12的扭矩N(见参考文献《静力学》2004,01 :32-32)。 [0023] Since the engine mount is fixed to a vertical panel 8 of the engine rotates a propeller shaft 5 is parallel to the optical axis 12, and the screw 12 and the optical axis of the engine 5 through the engine mount 8, the optical axis of the first fixing bracket 4, and a second optical axis fixing bracket 9 secured together, therefore, the torque on the optical axis 5 NI propeller engine torque can represent N 12 (see reference "statics" 2004,01: 32-32). 由于转动限位环3通过其矩形端卡合在扭矩传感器2的开口端的矩形槽中,这样,与转动限位环3连接的光轴5上的扭矩NI可通过转动限位环3传递给扭矩传感器2。 Since the rotation of the stop ring 3 by engagement of its rectangular end of the rectangular slot open end of the torque sensor 2, so that the rotational torque of the stop ring 3 on the optical axis 5 NI can be connected to ring 3 by limiting the rotation is transmitted to the torque 2 sensor.

[0024] 当螺旋桨发动机12启动时,会产生一个沿水平方向且指向远离发动机安装架8的垂直面板的推力F,由于固定在发动机安装架8的垂直面板上的螺旋桨发动机12的转动主轴与光轴5平行,根据力的平移原理,光轴5上的沿水平方向、对压力传感器10的压力Fl就可表示推力F,F1即为所要测量的推力,Fl可通过压力传感器10得到。 [0024] When the screw 12 starts the engine, generates a horizontal direction perpendicular to and directed away from the panel 8 engine mount thrust F., Since the engine mount is fixed to a vertical panel 8 of the engine rotates a propeller shaft 12 and the light parallel to shaft 5, in accordance with the principles of the translational force in the horizontal direction on the optical axis 5, the pressure of the pressure sensor 10 can Fl represents thrust F, F1 is the force to be measured, Fl can be obtained by the pressure sensor 10. 在力的平移过程中,会产生一个附加力矩N',根据右手法则,该附加力矩N'的力矩方向垂直于纸面向里,即与水平方向垂直,这样不会影响到扭矩及推力的测量结果。 During translation of the force, will generate one additional torque N ', right-hand rule, the additional torque N' moment oriented in a direction perpendicular to the paper, i.e., vertical and horizontal directions, this will not affect the measurement results of thrust and torque .

[0025] 下面进一步说明本实用新型所提供的装置的工作过程。 [0025] Next, operation will be described further apparatus according to the present invention is provided.

[0026]启动螺旋桨发动机12之后,扭矩传感器2和压力传感器10分别将测量值通过数据线传送至显示设备,测量人员可通过显示设备获取螺旋桨发动机12的扭矩和推力的测量值,将所得到的扭矩测量值和推力测量值分别与采用转速计测得的螺旋桨发动机12的转速值进行数据拟合,从而得到“扭矩-转速”曲线和“推力-转速”曲线。 [0026] Start the propeller after the engine 12, the torque sensor 2 and a pressure sensor 10, respectively, the measured values ​​through the data lines to the display apparatus, measuring person can take measurements of the torque and the thrust 12 of the propeller engines through the display device, the resulting torque and thrust measurement values ​​measured data can be fitted with the speed values ​​measured using tachometer propeller engine 12 to obtain a "torque - rotational speed" curve and the "push - rotational speed" curve.

[0027] 综上所述,以上仅为本实用新型的较佳实施例而已,并非用于限定本发明的保护范围。 [0027] In summary, the present invention above is only preferred embodiments are not intended to limit the scope of the present invention. 凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 Any modification within the spirit and principle of the present invention, made, equivalent substitutions, improvements, etc., should be included within the scope of the present invention.
