Embodiment Construction

[0021] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] A specific embodiment of the measuring tool for the axial deformation of the double inner ring double row ball bearing of the present invention:

[0023] Such as Figure 1~2 As shown, the tool for measuring the axial deformation of the double inner ring and double row ball bearing in this embodiment includes a support frame, a preloading device, a bearing loading device and a measuring device.

[0024] The support frame includes a base 11 and an instrument seat 3. A stepped hole for placing the base 11 is arranged on the instrument seat 3. The stepped hole includes a large hole with a larger aperture and a small hole with a smaller aperture. The base 11 is placed in the large hole of the stepped hole. middle. There are also stepped holes arranged on the base 11. The stepped holes on the base 11 and the stepped holes on the instrument base 3 comm...

Abstract

The invention relates to an axial deformation measurement tooling of dual-inner ring dual-row ball bearings. The axial deformation measurement tooling for the dual-inner ring dual-row ball bearings comprises a pretensioning device for applying a set preloading load to the dual-inner ring in the axial direction of a bearing; the measurement tooling further comprises a support frame for supporting the dual-row ball bearing in a pretensioning state and an axial loading device for axially loading the bearing in the pretensioning state; one of the support frame and the axial loading device which cooperate with each other correspondingly stops an outer ring of the bearing, and the other of the support frame and the axial loading device correspondingly stops an inner ring of the bearing; and themeasurement tooling also includes a measurement device for measuring the axial deformation of the dual-row ball bearing in an axial loading state. The measurement tooling can measure the axial deformation of the bearing, which can avoid the situation that the axial pretensioning forces of the inner rings of the bearings are inconsistent during manual loading due to individual differences of the detecting personnel, and can make the measurement result of the axial deformation of the inner ring more accurate.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a tool for measuring the axial deformation of a double inner ring double row ball bearing. Background technique [0002] As a bearing with strong support rigidity, high rotation precision and good vibration resistance, the miniature double inner ring double row ball bearing is widely used in the mechanism platforms of aviation, navigation and other fields, but due to its small overall size, this kind of bearing There are certain technical difficulties in the process of processing, assembling and testing. Taking the detection of the axial deformation of the miniature double inner ring double row ball bearing as an example, in the prior art, the axial deformation of the bearing is mainly realized by manually loading the outer ring of the miniature double inner ring double row ball bearing. In the testing and loading process, the operator needs to control the pretightening for...
