Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described below.

[0018] Implementation of the present invention provides a rotating shaft axial force measuring device, the measuring device includes a rotating shaft 1, a sensor unit 11 and a signal line 7; its composition is that the sensor unit 11 is sleeved and fixed on the corresponding The shaft 1 is connected to the corresponding slip ring 10 sleeved on the rotating shaft 1 through the signal line 7 on the corresponding unidirectional pressure sensor 5 .

[0019] The above-mentioned sensor unit 11 is clamped and fixed by two corresponding connecting discs 3 with a one-way pressure sensor 5 that is in close contact with the surface of the rotating shaft 1, and is clamped by two corresponding couplings 6 again. It is composed of two corresponding connecting discs 3 fixed; the rotating shaft 1 outputs the axial force of the rotating shaft to the slip ring 10 through the unidirectional for...

Abstract

The invention provides a rotary shaft axial force measuring device. The measuring device sleeves a rotary shaft in a fixed way, and a single direction force sensor and a signal line thereof are connected to a sliding ring which sleeves the rotary shaft to form the measuring device. The device has the advantages of simple structure, low cost, easy installation, and stable and reliable data transmission.

Description

technical field [0001] The invention relates to a method for measuring the axial force of a rotating shaft, which is a new device for measuring the axial force of a general rotating shaft. Background technique [0002] Rotating machinery, such as steam turbines, motors, fans, elevators, etc., are widely used in reality. The rotor system will generate a certain axial force due to the structure of the machine itself or under the action of the load during the working process. The axial load directly affects the selection of the bearing. The excessive axial force will directly lead to aggravated wear and aging of the bearing, causing mutual friction and collision between the rotating part and the stationary part, resulting in large vibration and noise, which will seriously affect the rotor system. of normal operation. Therefore, it is necessary to effectively measure the axial force of the rotating shaft, which is of great help to the design, selection and safe production of re...
