Description

Technical Field

[0001] This invention relates to an angle micro-motion rotation adjustment stage and observation system for analyzing the micro-damage morphology of rolling elements, belonging to the field of rolling bearing damage analysis technology. Background Technology

[0002] In bearing damage analysis, rolling element damage is a frequent problem. To understand the evolution of rolling element damage, it is usually necessary to record and observe damage characteristics, such as damage size, depth, and direction, at the initial stage of damage. Since the damage is relatively microscopic at the initial stage, it is necessary to use a high-magnification microscope for observation. In some cases, auxiliary tools are needed to manually adjust the angle to obtain a complete damage morphology. The original method is highly random. Under high magnification, the distance between the lens and the sample is close, which brings two problems. First, in order to avoid the adjustment auxiliary tools touching and damaging the lens, the space for movement is extremely small, usually only a few millimeters. Second, manual adjustment often results in over- or under-adjustment of the rotation angle. A special angle fine-motion rotation adjuster is needed to solve this problem.

[0003] In summary, existing bearing damage analysis methods suffer from technical problems such as extremely limited operational space and inaccurate rotation angles when manually adjusting the rolling elements, leading to low observation efficiency. Summary of the Invention

[0004] This invention addresses the technical problem of low observation efficiency caused by the extremely small operating space and inaccurate rotation angle when manually adjusting the angle of rolling elements during existing bearing damage analysis. It provides a micro-motion rotation adjustment stage for rolling element micro-damage morphology analysis, comprising an inclined limiting baffle, a rotation drive guide roller, a rotation servo drive motor, and a controller.

[0005] The rotating drive guide rollers are arranged in a set along the X-axis and Y-axis directions, wherein the rotating drive guide rollers along the X-axis are arranged below the rotating drive guide rollers along the Y-axis.

[0006] The number of inclined limiting baffles is 1 to 3, arranged along the circumference of the rolling body. The shape of the inner surface of the inclined limiting baffle is adapted to the shape of the lower part of the side surface of the rolling body, and together with the rotating drive guide roller, they form a funnel-shaped limiting structure.

[0007] The rolling element is placed in the funnel-shaped limiting structure and maintains contact with the rotation drive guide roller by its own weight;

[0008] The rotating guide rollers are driven by corresponding rotating servo drive motors, which can realize independent or coordinated rotation of the rolling elements around the X-axis and Y-axis. The rotating servo drive motors are electrically connected to the controller.

[0009] As another improvement of the present invention, the inner surface of the inclined limiting baffle is provided with a polytetrafluoroethylene layer.

[0010] As another improvement of the present invention, the surface of the rotating drive guide roller is covered with a silicone layer to increase the friction between it and the rolling element.

[0011] As another improvement of the present invention, the rotary servo drive motor and the rotary drive guide roller are connected by gear transmission.

[0012] As another improvement of the present invention, the gear is made of PA66 nylon material.

[0013] As another improvement of the present invention, the controller includes two knobs with damping function, which are used to control the rotation of two sets of rotation drive guide rollers around the X-axis and Y-axis directions, respectively.

[0014] As another improvement of the present invention, the displacement of each knob is configured to control the rotation speed of the rotation drive guide roller in the corresponding direction, and the displacement is proportional to the speed, thereby realizing stepless adjustment of the rotation speed.

[0015] As another improvement of the present invention, the rotating drive guide roller can rotate in both clockwise and counterclockwise directions.

[0016] As another improvement of the present invention, the micro-motion rotation adjustment stage for the rolling element micro-damage morphology analysis is suitable for the morphological observation and analysis of rolling element micro-damage under a high-magnification microscope.

[0017] The present invention also provides a rolling element micro-damage observation system, comprising:

[0018] The rolling element micro-damage morphology analysis angle micro-motion rotation adjustment stage as described in any one of claims 1 to 9 is used to support and drive the rolling element to perform precise angle micro-motion adjustment;

[0019] A high-powered microscope, with its objective lens aimed at the observation area of ​​the rolling body on the stage, is used to perform high-resolution optical magnification imaging of the microscopic damage morphology on the surface of the rolling body.

[0020] An image recording device is connected to the optical path or output end of the high-power microscope to acquire and store image or video data of the microscopic damage morphology.

[0021] The beneficial effects of this invention are:

[0022] The device of this invention enables observation of rolling bodies under a high-magnification microscope, allowing for precise angle adjustment during microscopic damage analysis of the rolling body using a high-magnification microscope. This improves the accuracy of angle adjustment. It avoids the problem of collisions with the high-magnification microscope lens caused by limited operating space during traditional manual adjustments. Non-contact adjustment via a remote controller significantly reduces the risk of equipment damage. The funnel-shaped limiting structure utilizes the rolling body's own weight for natural positioning and loading, eliminating the need for complex clamping mechanisms and making it suitable for rolling bodies of different sizes. Dual-axis independent drive allows for 720° omnidirectional rotation of the rolling body, facilitating comprehensive observation and complete morphological recording of the damaged area, making it particularly suitable for three-dimensional analysis of microscopic damage.

[0028] The number of inclined limiting baffles 1 is 1 to 3, arranged along the circumference of the rolling body. The inner surface shape of the inclined limiting baffle 1 is adapted to the lower part of the side surface of the rolling body, and together with the rotating drive guide roller 2, they form a funnel-shaped limiting structure.

[0029] The rolling element is placed in the funnel-shaped limiting structure and maintains contact with the rotation drive guide roller 2 by its own weight;

[0030] The rotating drive guide rollers 2 are driven by corresponding rotating servo drive motors 3, which can realize the independent or coordinated rotation of the rolling elements around the X-axis and Y-axis. The rotating servo drive motors 3 are electrically connected to the controller.

[0031] The stage, high-powered microscope, and image recording device are arranged in concert to form an integrated observation system for achieving comprehensive observation of the rolling body surface, recording and analyzing its morphology from multiple angles. Using this invention for high-powered microscope observation of the rolling body allows for precise angle adjustment during microscopic damage analysis, improving the accuracy of angle adjustment.
