Description

Technical Field

[0001] This utility model relates to the field of mechanical testing technology, and in particular to a sprocket tooth assembly testing mechanism. Background Technology

[0002] As a core component of chain drives, the sprocket's tooth profile accuracy directly affects transmission efficiency and stability. In the industrial sector, chain drives are widely used in various mechanical equipment, such as engines, conveyors, and textile machinery. With the continuous development of industrial automation, sprockets play an increasingly important role in modern industrial production, crucial for ensuring the normal operation of equipment and efficient production. Therefore, with the continuous improvement of industrial automation levels, the requirements for sprocket tooth profile accuracy are becoming increasingly stringent. The precision of the sprocket tooth profile is related to the performance of the entire transmission system. High-precision teeth can effectively improve transmission efficiency, reduce energy loss, enhance transmission stability, and reduce vibration and noise.

[0003] In existing technologies, sprocket tooth profile inspection mainly utilizes the following methods. Manual visual inspection is a common method, where operators directly observe the tooth profile to determine its integrity and quality. This method is relatively simple and doesn't require complex equipment, but it demands a high level of operator experience, and different individuals may have different judgment standards. Another method uses calipers or templates, employing specialized measuring tools to measure tooth dimensions. This method achieves high accuracy but requires significant time and effort. In recent years, optical inspection and laser scanning technologies have also been increasingly applied to tooth profile inspection. These technologies utilize advanced optical principles and laser technology to obtain detailed information about the tooth profile. However, these technologies require specialized equipment and operators, resulting in high equipment costs, complex operation processes, and stringent environmental requirements for the inspection process.

[0004] However, existing inspection methods have certain drawbacks. While caliper or template measurements offer high precision, their efficiency is low, making them unsuitable for large-scale production. Furthermore, they cannot be automated, leading to increased labor costs and limited production efficiency. This makes current inspection technologies inadequate for mass sprocket production, necessitating a more efficient, accurate, and automated inspection method. Utility Model Content

[0006] This application provides a sprocket tooth assembly and inspection mechanism, which adopts the following technical solution: A sprocket tooth assembly inspection mechanism includes a mounting base, on which an internal gear ring is provided for meshing with the sprocket to be inspected. A limiting post is provided in the middle of the mounting base, which is used to cooperate with the center hole of the sprocket to detect the offset of the sprocket's center position.

[0007] By adopting the above technical solution, the sprocket tooth profile assembly and inspection mechanism designed in this utility model can detect the tooth profile error of the outer periphery of the sprocket by meshing the inner tooth ring with the sprocket to be inspected, and detect the offset of the center position of the sprocket by cooperating with the limiting post and the center hole of the sprocket. It can confirm that the sprocket tooth profile meets the design tooth profile tolerance, and ensure that the chain drive is smooth and free from wobbling, friction and other defects after installation.

[0008] Preferably, the mounting base also includes a portion that matches the sprocket gap, used to detect the overall structural error of the sprocket.

[0009] By adopting the above technical solution, during use, the sprocket is placed in the inner tooth ring of the mounting base and meshes with it. The overall structural error of the sprocket is detected by using the gap between the mounting base and the sprocket.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] This utility model discloses a sprocket tooth assembly inspection mechanism, such as... Figure 1 and Figure 2As shown, it includes a mounting base 1, an internal gear ring 2, and a limiting post 3. The mounting base 1 is provided with an internal gear ring 2, which is used to mesh with the sprocket to be tested. The mounting base 1 is provided with a limiting post 3 in the middle, which is used to cooperate with the center hole of the sprocket to detect the offset of the sprocket's center position. This can comprehensively detect the tooth shape and center position of the sprocket and promptly detect the manufacturing error of the sprocket.

[0024] Specifically, the mounting base 1 includes a base plate 11 and a support ring 12. The base plate 11 is typically a flat plate structure that provides a stable support foundation for the entire testing mechanism. It is generally made of metal, such as steel or aluminum alloy, to ensure sufficient strength and stability. The support ring 12 is annular in structure, surrounding the base plate 11, and can be fixed to the base plate 11 by welding or bolting. It serves to support and position the internal gear ring 2, enabling it to accurately mesh with the sprocket to be tested.

[0025] The internal gear rings 2 are circumferentially distributed along the support ring 12. The teeth of the internal gear rings 2 are elliptical, and they are spaced apart. The internal gear rings 2 are ring gear structures made of metal. Their elliptical teeth are designed according to the standard tooth profile of sprockets to more accurately detect whether the sprocket teeth meet the requirements. The spaced arrangement helps reduce friction when in contact with the sprocket, avoiding damage to the sprocket teeth. The internal gear rings 2 are embedded in the inner circumferential edge of the support ring 12 through interference fit or key connection, ensuring their secure and accurate installation.

[0026] The limiting post 3 is located in the middle of the mounting base 1. It is usually cylindrical, and its diameter matches the diameter of the center hole of the sprocket to be tested, ensuring accurate insertion into the center hole for testing. The limiting post 3 can be a solid metal post or a hollow plastic tube, as long as it meets the positioning requirements during testing. The limiting post 3 is generally fixed to the mounting base 1 by means of threaded connection or welding.

[0027] By engaging the internal gear ring 2 with the sprocket, it is possible to detect whether there are significant errors in the outer tooth profile of the sprocket; by engaging the limiting pin 3 with the center hole of the sprocket, it is possible to detect whether there is any deviation in the center of the sprocket. This combination method can comprehensively detect the key parameters of the sprocket, improving the accuracy and reliability of the detection.

[0028] Mounting base 1 also includes a portion that mates with the sprocket clearance. This portion is typically a raised or recessed structure designed according to the sprocket's shape and tooth clearance. For example, when the sprocket's tooth clearance is a regular trapezoid, the mating portion can be designed as a corresponding trapezoidal protrusion to better fit into the sprocket clearance. This portion can detect the extent of the sprocket's overall structural error. By observing its fit with the sprocket clearance, it can determine whether there are any deformations or deviations in the overall structure of the sprocket during manufacturing.

[0029] The mounting base 1 has multiple mounting holes 4, which are circular holes that penetrate the mounting base 1. The mounting base 1 and the testing structure are connected through the mounting holes 4, and the connection method can be bolt connection. The bolts pass through the mounting holes 4, firmly fixing the mounting base 1 and the testing structure together, ensuring the stability of the relative positions of the components during the testing process. The number and position of the mounting holes 4 can be adjusted according to the actual needs of the testing structure.

[0030] The surface of the substrate 11 is coated with an anti-slip layer 5, which can be a rubber coating or a frosted coating, etc. A rubber coating has good elasticity and friction, enabling the sprocket to remain stable after engagement and preventing slippage; a frosted coating achieves the anti-slip effect by increasing surface roughness. The anti-slip layer 5 effectively prevents the sprocket from shifting during the testing process, ensuring the accuracy of the test results.

[0031] The implementation principle of this embodiment is as follows: The sprocket tooth profile assembly and inspection mechanism of this embodiment, through the coordinated work of components such as the mounting base 1, the internal gear ring 2, and the limiting post 3, can efficiently and accurately detect the tooth profile and center position of the sprocket. The detection of the meshing between the internal gear ring 2 and the sprocket, the detection of the fit between the limiting post 3 and the sprocket's center hole, and the detection of the overall structure based on the gap in the mating sprocket portion, fulfills multiple inspection requirements for the sprocket. The mounting hole 4 ensures the assembly stability of the inspection mechanism, while the anti-slip layer 5 and the positioning rod 6 further improve the stability of the sprocket during the inspection process, thereby improving the reliability of the inspection results. Compared with existing technologies, this inspection mechanism is simple to operate, can achieve a certain degree of automated inspection, effectively meets the needs of mass production, greatly improves production efficiency, reduces labor costs, and provides a more effective solution for sprocket quality inspection.

[0032] Example 2 The difference between this embodiment and the previous embodiment is that a detachable positioning rod 6 is also provided on the substrate 11. The positioning rod 6 is typically a slender rod-shaped structure, and its size and shape are designed according to the holes on the sprocket to be tested. When the sprocket has corresponding holes, the positioning rod 6 can be inserted into the holes to fix the sprocket in place, further improving the stability of the test. The positioning rod 6 can be connected to the substrate 11 by plugging and unplugging. When the sprocket does not have holes, it can be removed to facilitate the testing of different types of sprockets.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
