New axial force measuring device and method based on tension and pressure sensor

Abstract

The invention relates to a new axial force measuring device and method based on a tension and pressure sensor. The axial force measuring device comprises an adjusting and fixing nut, a push-pull force meter, a dynamometer seat, a key, a bearing pedestal, an axial force wrapping device, a bearing group, a cylindrical roller bearing, a shaft, a shaft-end threaded piece and a locking nut. According to the invention, an axial force is separated from a radial force by utilizing the cylindrical roller bearing and an angular contact bearing group (or a conical roller bearing group), influence of the radial force on axial force measurement is avoided, and the axial force can be measured more accurately; fine adjustment of the position of the shaft in the axial direction is realized via the adjusting and fixing nut; the bearing group, the axial force wrapping device and the like converts the axial force of the rotating shaft into a static axial force, and the push-pull force meter realizes measurement in both push and pull directions; and the shaft-end threaded piece can increase the axial length of original equipment, and reduce the refitting workload of axial force measurement as possible. It is proved that the method can be used to measure the axial force accurately and conveniently.

[0002] For the rotating shaft supported by rolling bearings, some methods of measuring the axial force indirectly measure the axial force through the measurement of the strain of the relevant parts. This measurement method is difficult to implement, and the accuracy of the converted axial force still needs to be verified; some It is a direct or approximate direct measurement of axial force, such as lever method, force measuring ring method, existing tension and pressure sensor method, etc. These methods do not rule out the influence of radial force on the measurement results of axial force, and need to be improved
