Abstract

The invention belongs to the technical field of precision rolling bearings, and relates to a matching method for special bearings for inertial navigation platforms. The matching steps are: (1) preselection, (2) pairing, (3) measuring and correcting the protrusion of the end face of the single set of bearings, (4) measuring and correcting the deformation of the inner ring of the paired bearing, (5) testing the paired bearing starting friction torque. The method of the invention can reduce the error of the pre-tightening force of the paired bearings, make the starting friction torque of the bearings meet the requirements, and greatly improve the performance of the inertial navigation platform.

Description

Matching method of special bearing for inertial navigation platform technical field The invention belongs to the technical field of precision rolling bearings, and relates to a matching method for special bearings for inertial navigation platforms. Background technique The inertial navigation platform is an important device to establish a stable three-axis coordinate system for the aircraft to control the flight trajectory and attitude of the aircraft. The platform frame support bearing used in it is the main guarantee for the accuracy, reliability and life of the inertial navigation platform. . The structural forms of support bearings include deep groove ball bearings, angular contact ball bearings, double row angular contact ball bearings, etc., and the paired angular contact ball bearings are most used in inertial navigation platforms. In order to realize the technical requirements of inertial navigation platform for bearings, a lot of research has been done on inertia...
