Embodiment Construction

[0045] The present invention will be further elaborated below in combination with specific embodiments.

[0046] A method for setting the stiffness matrix of a crossed cylindrical roller slewing bearing through mechanical modeling. The crossed cylindrical roller slewing bearing is mainly composed of an inner ring, an outer ring and cylindrical rollers. Under the action of an external load, the slewing bearing Relative displacement of the inner ring relative to the fixed outer ring, assuming an external radial load , axial load and overturning moment load Under the combined action of , the corresponding radial displacement, axial displacement and inclination displacement of the inner ring are respectively: , and , in the axial plane of the bearing, the raceway of the crossed roller slewing bearing is composed of four line segments, one raceway between the loaded roller and the inner raceway and the other raceway on the outer raceway in the opposite direction The two...

Abstract

The invention provides a method for arranging a crossed cylindrical roller turnable bearing stiffness matrix through mechanics modeling. A mechanical model considers the nonlinearity of the contact between a roller and a raceway for the working condition that a radial load, an axial load and an overturning moment load act simultaneously, and is more accurate and practical compared with a traditional superposition method; the mechanical model comprises the main design parameters of a turntable bearing, a basis can be supplied for the reasonable selection of the design parameters by using the result obtained by the model, and optimizing is further performed on the design parameters; the stiffness matrix reflects the non-deformability of the crossed cylindrical roller turntable bearing when bearing the radial load, the axial load and the overturning moment load; the stiffness matrix arranged through mechanics modeling not only can be used for judging whether the model selection of the turntable bearing is right or not, but also can reflect the stiffness margin of the turntable bearing.

Description

technical field [0001] The invention relates to the field of design and analysis of crossed cylindrical roller slewing bearings, in particular to a method for setting the stiffness matrix of crossed cylindrical roller slewing bearings through mechanical modeling. Background technique [0002] Crossed cylindrical roller slewing bearings have the advantages of compact structure, strong load capacity, and high rigidity, and are used in the azimuth and slewing systems of precision mechanical systems such as radar antennas, test turntables, and industrial robots. The crossed cylindrical roller slewing bearing is the key component for these main engines to realize the azimuth control and rotary motion of the moving parts. During the working process of the main engine, the cross cylindrical roller slewing bearing mainly bears the combination of radial load, axial load and overturning moment load. effect. The rigidity of the crossed cylindrical roller slewing bearing is an i...
