A structure that can accurately measure the axial force of the turbine without compressing the outer ring of the bearing

Abstract

The invention discloses a structure capable of accurately measuring the axial force of a turbine without compressing the outer ring of the bearing. The pin, the second adjusting pad, the second pin and the shaft sleeve; through the first pin, the second adjusting pad, the second pin, the pair of convex teeth on the bearing force sensor and the boss on the bearing, the rotation of the outer ring of the bearing is limited. Rotate, the compression nut is threadedly connected with the support shell, and pressed to the first adjustment pad to ensure that the compression nut can be fully compressed, limiting the space for axial movement of the bearing, and leaving a certain gap between the compression nut and the outer ring of the bearing. Axial clearance, will not press against the bearing outer ring. This structure realizes the reliability of the sensor when the axial force sensor works without pre-tightening pressure. At the same time, the anti-rotation measures ensure that the outer ring of the bearing does not rotate, and the bearing can work safely.

Description

technical field [0001] The invention relates to a measuring structure, in particular to a structure capable of accurately measuring the axial force of a turbine without compressing the outer ring of a bearing. Background technique [0002] Turbomachinery is widely used in the fields of energy power, aerospace and near-space combined engines. Under the requirements of high power, high performance and high efficiency of the engine, the flow rate of the turbomachinery is large, the pressure is high, and the axial force is also significantly increased. Accurately measure the axial force Force is very important for axial force balance of turbomachinery system. [0003] In the traditional turbomachinery axial force measurement scheme, the bearing is pressed on the axial force sensor. Since the outer ring of the bearing has the requirement of anti-rotation, it is necessary to compress the outer ring of the bearing so that the axial force sensor can withstand a relatively large load...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problem that the existing turbine needs to be compressed to prevent the rotation of the outer ring of the bearing when measuring the axial force, thereby affecting the measurement accuracy of the axial force sensor, the present invention provides a non-compressed bearing outer ring that can be accurately Structure for Measuring Turbine Axial Force
