Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] It should be noted that if there are directional indications involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture. If the specific posture changes , then the directional indication changes accordingly.

[0032] In addition, if there are descriptions involving "first", "second" and so o...

Abstract

The invention provides a hub bearing negative clearance calculation method and device, a storage medium and equipment. The method comprises the following steps ofobtaining a displacement parameter ofan inner ring of a to-be-measured hub bearing when an external force F is applied to an inner flange of the to-be-measured hub bearing, acquiring a displacement parameter of an inner ring of the hub bearing with the initial clearance of zero when the external force F is applied to the inner flange of the hub bearing with the initial clearance of zero,and according to F, Ac1 and Ac02, calculating the negative clearance value delta of the to-be-measured hub bearing. The negative clearance value is calculated according to the relationship among the applied external force, the displacement of theinner ring of the to-be-measured hub bearing and the displacement of the inner ring of the hub bearing with the initial clearance being zero, the negative clearance value can be detected before the to-be-measured hub bearing leaves a factory, the detection result can be reproduced, and the accuracy is high.

Description

technical field [0001] The present invention relates to the technical field of bearing negative clearance, in particular to a calculation method, device, storage medium and equipment for wheel hub bearing negative clearance. Background technique [0002] The negative clearance parameter is one of the key factors determining the performance of the hub bearing unit. The rationality of its design and processing will directly affect the working life of the hub bearing unit and the driving safety of the whole vehicle. Therefore, it is necessary to negatively play the finished product of the hub bearing unit. Clearance detection, and use the detection results as one of the indicators to judge whether the hub bearing is qualified or not. Existing negative clearance testing of finished hub bearing units does not have the ability to repeatedly test the same product, and the reproducibility of testing cannot be achieved, and the testing is pre-riveting testing, which cannot reflect th...
