Problems solved by technology

[0002] A certain type of aero-engine accessory casing (hereinafter referred to as the attachment casing) has a total of 5 output shafts, all of which are output by internal splines; the maximum speed of the output shaft exceeds 18000r / min, and different ports are connected to real accessories with different functions in actual use. Pump; during the factory test, each output shaft is loaded with a low-quality, low-speed, low-speed, and long-life simulated hydraulic pump. This is because the real accessory pump has a high speed, is easily damaged, and has a high cost; at the same time, it is required to accurately measure the loading power

Abstract

The invention discloses a high speed shaft system with a torque measuring function, and mainly solves the problems that real accessories are prone to being damaged and the cost is high on trial. The high speed shaft system with the torque measuring function comprises a transferring mechanism (1), a hinge hole bolt A (2), a hinge hole bolt B (5), a membrane A (3), a membrane B (6), an intermediateshaft (4), a transferring flange (7), a high speed torque meter (8), a conical surface flange (9), and a gear case high speed shaft (10); the high speed shaft system with the torque measuring functionis characterized in that a spline end opening of the connected device is connected with the transferring mechanism (1) provided with an outer spiline shaft; a right end flange of the transferring mechanism (1) is connected with the left end of the intermediate shaft through the hinge hole bolt A (2) and the membrane A (3); the right end of the intermediate shaft (4) is connected with the left endof the transferring flange through the hinge hole bolt B (5) and the membrane B (6); the left end of the transferring flange is connected with the high speed torque meter; and the high speed torque meter (8) is connected with the a load gear case high speed shaft (10) through the conical surface flange (9). The high speed shaft system with the torque measuring function has the characteristics ofreliable connection, on-line torsion measuring, compact structure and high working speed.

Description

technical field [0001] The invention relates to the field of mechanical transmission, and relates to a high-speed shaft system capable of measuring torque in the field of mechanical transmission, which is applied to a high-speed shaft system with torque measurement requirements, in particular to a high-speed shaft system with a torque measurement function. Background technique [0002] A certain type of aero-engine accessory casing (hereinafter referred to as the attachment casing) has a total of 5 output shafts, all of which are output by internal splines; the maximum speed of the output shaft exceeds 18000r / min, and different ports are connected to real accessories with different functions in actual use. Pump: During the factory test, each output shaft is loaded with a simulated hydraulic pump with low speed, low speed and long life. This is because the real accessory pump has a high speed, is easily damaged, and has a high cost; at the same time, it is required to accurate...
