Problems solved by technology

However, because the device is placed inside and the environment is complex, the signal is unstable, the speed is too fast, errors are prone to occur, and the accuracy is not high
[0005] Due to the relatively high internal temperature of the engine, the speed measuring device needs to be designed to adapt to complex environments such as high temperature resistance, and the speed measuring structure is complex. Most magnetic ring structures need to be customized according to the main shaft and locking device, which is expensive and has a long cycle. Once maintenance is required, it needs to be replaced. It is troublesome to disassemble the whole machine

Embodiment Construction

[0056]In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it can be directly connected or indirectly connected through an intermediary, it can be the internal communication of two elements or the interaction relationship between two elements. The "first", "second" and similar words mentioned in this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Likewise, words like "a" or "one" do not denote a limitation in number, but indicate that there is at least one. In the implementation of this application, "and / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which may mean: A exists alone, A and B ex...

Abstract

The invention belongs to the technical field of turbojet engine speed measurement, and particularly discloses a micro turbojet engine speed measurement device based on 3D printing. The device comprises a locking nut assembly connected with the end, close to an air inlet channel, of a torque transmission shaft of the turbojet engine, a magnet installed in the locking nut assembly, and a speed measurement sensor assembly installed on the air inlet channel and used in cooperation with the magnet. According to the invention, the magnet is arranged on the locking nut assembly for fixing the torque transmission shaft, and the speed measurement sensor assembly used for measuring the rotating speed in cooperation with the magnet is arranged on the air inlet channel; the measurement of the rotating speed is effectively realized; and the torque transmission shaft and a rotor assembly in the turbojet engine can be effectively fixed.

Description

technical field [0001] The invention relates to the technical field of turbine engine speed measurement, and more specifically, relates to a 3D printing-based miniature turbojet engine speed measurement device. Background technique [0002] As a new field to promote the development of energy and power systems, turbojet engine has the advantages of high speed, small size, light weight, large thrust-to-weight ratio, and wide application range. It is widely used in small unmanned aerial vehicles and model airplanes. [0003] During the operation of the engine, the rotational speed is a very important operating parameter, and its size determines the power propulsion and operating state of the engine, so measuring the rotational speed is of great significance. Traditional methods of measuring rotational speed generally include electromagnetic pulse, photoelectric and Hall effect. [0004] There is a device for measuring the speed inside the general engine, which is used to contr...
