Abstract

The invention discloses a radial loading device for thin-wall bearing vibration measurement. The radial loading device comprises a bottom plate; a thin-wall bearing vibration measurer arranged on thebottom plate, wherein an inner ring of a to-be-detected thin-wall bearing is arranged on a main shaft of the thin-wall bearing vibration measurer; a pair of radial loading devices arranged on the bottom plate, wherein the pair of radial loading devices are arranged at the left side and the right side of the to-be-tested bearing; a loading tungsten wire is arranged on each radial loading device, and the loading tungsten wire can relatively move in relative to the to-be-tested bearing, thereby performing loading and unloading on the to-be-tested bearing. The radial loading is performed by adopting the loading tungsten wire so as to guarantee that the loading force is uniformly distributed; the device adopts the left-right symmetric loading, the loading force can be automatically compensated,and the deformation of the thin-wall bearing in the loading process can be well solved.

Description

technical field [0001] The invention relates to the field of vibration measurement of thin-walled bearings, in particular to a radial loading device for vibration measurement of thin-walled bearings. Background technique [0002] The harmonic drive transmission includes three basic components: wave generator, flexible spline, rigid spline and flexible bearing. Among them, the flexible bearing is the core component, and the transmission meets the performance requirements of high reduction ratio through the elastic deformation of the bearing. Flexible thin-walled bearings (thin-walled bearings) are now widely used in industrial robots, and have high requirements for various performance parameters of the bearings, so the various test requirements for flexible thin-walled bearings are also extremely strict. Especially the load requirements during the test. [0003] However, the setting of the traditional loading device is unidirectional axial loading plus measurement of bearin...
