Description
technical field [0001] The invention belongs to the field of measurement of elastohydrodynamic oil film lubrication with high secondary line contact, and in particular relates to an experimental simulation device for measuring a lubricating oil film of a tapered roller bearing under different motion state conditions and a contact pair adjustment method. Background technique [0002] Tapered roller bearings are widely used in various industries in the industrial field because of their remarkable advantages of bearing compound loads (both bearing radial force and axial force). In tapered roller bearings, there is a linear contact between the tapered rollers and the raceway. This contact method can distribute the load over a large area, so that the tapered roller bearing has good load carrying capacity. [0003] At present, the numerical simulation of the lubrication state of tapered roller bearings is relatively mature. In terms of experimental research, bench experiments are...
