Spherical torsional moment measuring device for thrust bearing in working state

Abstract

The invention relates to the field of thrust bearing mechanical parameter measuring, aims to solve the problems that the existing torque measuring cannot truly reflect the real condition of a bearingin a working state and the reliability of a measuring result is low, and provides a spherical torsional moment measuring device for a thrust bearing in a working state, the spherical torsional momentmeasuring device comprises a thrust bearing seat, a fixed seat and the thrust bearing seat are opposite at an interval along the axial direction; an ring groove is defined in the outer peripheral surface of a thrust disc, and a tested thrust bearing assembly is arranged in the ring groove in a matched mode; the thrust disc is provided with a through hole, and the inner surface of the through holeis provided with an inner spherical arc surface; a matching part is arranged at the rear part of a ball head pull rod, and the forward surface of the matching part is an outer ball arc surface; the ball head pull rod penetrates through the through hole until the front end extends to the fixed seat; an axial loading device is connected with the ball head pull rod; and a torsion operation structureis connected to the rear portion of the thrust disc. The spherical torsional moment measuring device has the advantages that the measuring state conforms to the actual working state, the measuring result can truly reflect the real situation of the working state, and measuring and judgment are accurate and reliable.

Description

technical field [0001] The invention relates to the field of thrust bearing mechanical parameter measurement, in particular to a spherical torsional moment measuring device under the working state of the thrust bearing. Background technique [0002] At present, most of the thrust bearings used in various generator sets use a spherical fit structure to realize the self-positioning ability of the bearing. The measured torque cannot reflect the real situation of the thrust bearing in the working state, because after the thrust bearing receives the thrust, due to the relative movement of the tile body and the bush sleeve, the contact part of the spherical surface and the friction of the spherical surface Factors such as coefficients and other important factors that affect the spherical torsional moment have undergone great changes, which has resulted in the loss of self-positioning ability of many thrust bearings in the process of production or maintenance, but the spherical tor...
