Embodiment Construction

[0034] The present invention will be described in further detail below.

[0035] An embodiment of the present invention provides a transmission system. figure 1 The schematic structural diagram of the transmission system provided for an embodiment of the present invention, such as figure 1 As shown, the transmission system includes: a gear 1, a transmission shaft 2, a flat key 3 and a strain sensor.

[0036] Exemplarily, the gear 1 and the transmission shaft 2 use the flat key 3 to transmit power; the strain sensor is arranged on the gear 1 and is arranged adjacent to the flat key 3;

[0037] The strain sensor is used to carry out the strain test of the gear 1 .

[0038] Optionally, the strain sensor is arranged facing the rotation direction of the flat key 3 . refer to figure 1 , when the rotation direction of the flat key 3 is clockwise, the strain sensor is arranged on the right side of the flat key 3 .

Abstract

The invention provides a transmission system, and an acquisition method for a gear strain measuring point. The transmission system comprises a gear, a transmission shaft, flat keys and strain sensors;the gear and the transmission shaft adopt the flat keys for power transmission; the strain sensors are arranged on the gear, and are adjacent to the flat keys; and the strain sensors are used for strain test of the gear. According to the transmission system, and the acquisition method for the gear strain measuring point, the number of the strain sensors in a transmission gear strain test system is reduced greatly.

Description

technical field [0001] The invention belongs to the field of strain measurement of transmission gears, and in particular relates to a transmission system and a method for acquiring strain measurement points of gears. Background technique [0002] In the helicopter transmission system, the transmission gear is the carrier that transmits power and bears load. Its working environment is harsh and changeable, and it is the most prone to failure structure, and the transmission gear is a non-redundant design, once it fails, it will cause serious accidents. Since the transmission gear strain is related to its various failure modes, accurate measurement of the transmission gear strain is of great practical significance to obtain the gear running state and monitor the gear stress state in real time. The speed of the transmission gear of the helicopter is high, and the existence of the gearbox forms a harsh environment with extremely narrow space, rich oil and high temperature, which...
