Propeller thrust and torque measuring apparatus

Abstract

The present invention provides a propeller thrust and torque measuring apparatus. With the propeller thrust and torque measuring apparatus adopted, the technical problems of complex structure, low load carrying capacity, poor stability and high maintenance cost of an existing thrust and torque measuring apparatus can be solved. The propeller thrust and torque measuring apparatus comprises a vertical transmission shaft, a horizontal transmission shaft, a shaft sleeve, a supporting sword, a connecting body, an outer connecting shaft, an inner connecting shaft and a servo motor; the vertical transmission shaft is supported on the shaft sleeve through a first bearing; the upper end of the vertical transmission shaft is shafted to the output shaft of the servo motor; the horizontal transmission shaft is supported on the connecting body through a second bearing; the horizontal transmission shaft is engaged with the vertical transmission shaft through a circular-arc bevel gear set; after passing through the supporting sword, the shaft sleeve is fixedly connected with the connecting body; a guide hole penetrating the outer connecting shaft along an axial direction and a mounting groove communicated with the guide hole are formed in the outer connecting shaft; a thrust and torque measuring element is arranged in the mounting groove; and the inner connecting shaft and the horizontal transmission shaft extend into the mounting groove through two ends of the guide hole respectively and are shafted to the thrust and torque measuring element through a gear type coupling.

Description

technical field [0001] The present invention relates to measuring equipment, in particular to measuring equipment for propeller thrust and torque. Background technique [0002] When designing and producing the propeller, it is necessary to detect the thrust and torque of the propeller through the thrust and torque measuring equipment to analyze and improve the theoretical design. [0003] The existing domestic thrust and torque measurement equipment has a complex structure, low load capacity, and poor stability, while the load capacity and stability of imported thrust and torque measurement equipment are greatly improved compared with domestic equipment, but its structure is also complicated and maintenance The cost is high; at the same time, domestic and imported thrust and torque measurement equipment cannot measure the deviation of the actual propulsion direction of the propeller.
