Problems solved by technology

The working speed of the starter is as high as 40,000 rpm. Conventional electromechanical equipment such as tachogenerators cannot withstand such a high speed. After extensive research, there is currently no suitable device in China that can realize this function, and it needs to rely on the pilot's manual judgment. , the accuracy is poor

Embodiment 1

[0014] Example 1. Such as figure 1 As shown, it mainly includes a casing 1 and a centrifugal assembly 2 installed in the casing 1, a pressure rod assembly 3, a micro switch 4 and an electrical connector 5. The casing 1 is a structural part, and all components are installed in it. Its shape should be considered in the installation interface of the starter. The centrifugal assembly 2, the pressing rod assembly 3, the pressing rod assembly 3 and the micro switch 4 are installed on the same axis of the housing 1. When working, the centrifugal assembly 2 acts on the pressing rod assembly 3, and the pressing rod assembly 3 acts on the micro switch 4 , the contacts of the micro switch 4 are connected to the two terminals on the electrical connector 5 . When the micro switch 4 is triggered, the internal reed changes, the circuit is connected, and a signal is sent. Such as figure 2 As shown, the centrifugal assembly 2 includes a gear shaft 6, a centrifugal block 10 and a push ...

Abstract

The invention discloses a centrifugal switch; the centrifugal switch comprises a shell (1), a centrifugal component (2), a compressive bar component (3), a microswitch (4) and an electric connector (5) which are arranged inside the shell (1); the centrifugal component (2), the compressive bar component (3) and the microswitch (4) are arranged on the same axis of the shell (1); and the microswitch (4) is connected with the electric connector (5). The centrifugal switch effectively solve a key technology of converting a high rotating speed into an electric signal, can be applied to high speed working equipment such as starters of airplanes and the like, can timely and accurately convert a high rotating speed mechanical signal into the electric signal, has the characteristics of reasonable structure, compactness, novelty and the like and is worth of market promotion.

Description

technical field [0001] The invention relates to a centrifugal switch capable of converting the rotational speed signal of a high-speed rotating machine into an electrical signal. Background technique [0002] For the starter of the aircraft, it needs to reach a high speed to start normally. After reaching the working speed, if the speed continues to increase, it will cause damage to the starter. At this time, an effective device is needed to make the starter reach the working speed. Afterwards, an electric signal is sent out timely and accurately to remind the pilot to turn off the starter. The working speed of the starter is as high as 40,000 rpm. Conventional electromechanical equipment such as tachogenerators cannot withstand such a high speed. After extensive research, there is currently no suitable device in China that can realize this function, and it needs to rely on the pilot's manual judgment. , with poor accuracy. Contents of the invention [0003] The technica...
