Problems solved by technology
[0005] In addition, there are very few relevant documents and products about high-speed transmission error testing in China. Although there are equipment for testing high-speed transmission errors abroad, the price is too high (for example, the T20 machine tool is more than 400,000 US dollars), and it is difficult to be widely used.

The invention discloses an aviation high-speed gear dynamic transmission error measuring system, comprising two pairs of magnetic grid encoders, respectively installed on shaft ends of an input shaft and an output shaft of a to-be-tested high-speed gear. The two pairs of magnetic grid encoders are connected with a test computer through an acquisition card and an externally-connected storage array. A software system in the test computer is programmed and designed by using a virtual instrument principle based on a LabVIEW platform, and comprises a data acquisition program, a data transmission program, and a data processing program. After a device is started and after rotating speed of a motor is stable, the data acquisition program is opened to write in transmission error data, and after the gear stops, angular displacement of the input shaft and the output shaft of the high-speed gear is obtained, and the data processing program processes the acquired data, so as to obtain high-speed gear dynamic transmission error data. The system provides an effective reference method for high-speed, high-precision, and big data gear transmission error tests, and the test system is simple in operation and easy in maintenance.
Description
technical field [0001] The invention belongs to the field of gear transmission and relates to a dynamic transmission error measurement system for aviation high-speed gears. Background technique [0002] Gear transmission error, as one of the most important causes of vibration and noise in gear transmission systems, has been a hot issue for gear designers and application engineers for decades. The accurate test and scientific evaluation of the transmission error of the gear transmission system is an important guarantee for the transmission accuracy and stability of the gear transmission system, and it also provides a reference for the design, manufacture and optimization of the gear. However, the current transmission error test system is usually carried out at low speed and light load, and the transmission system is tested as an ideal system without vibration. According to the literature, the gear with a peripheral speed greater than 25m / S is called a high-speed gear. Gears ...
