[0002] A gear is one of the core components of a modern mechanical transmission system, and its mechanical properties affect the stability and transmission efficiency of the entire transmission system. During the use of gears, the gears rotate at a certain speed and bear a certain torque, which will cause slight deformation on the contact surface between the two gears.

[0003] Due to factors such as gear processing accuracy, abnormal noises such as whistling sounds and knocking sounds may occur during the meshing contact of two gears, affecting the user experience. Currently, if abnormal noises occur in gears after leaving the factory, they are often further processed by grinding to reduce the abnormal noises. However, there are often problems of excessive grinding amount and large workload in the further processing process. Summary of the Invention

[0028] In the first aspect of this application, a method for setting gear grinding parameters is provided. Figure 1 It is a schematic flowchart of an embodiment of the method for setting gear grinding parameters provided by this application. Combining Figure 1 , this method includes the following steps:

[0029] S101: Obtain the meshing deformation characteristics and meshing noise characteristics of the gear during the meshing process.

[0030] Among them, the gear in this application can be a gear that requires relatively high rotational speed and relatively high torque during the working process. For example, it can be the transmission gear of the drive motor of a vehicle. For such a gear that requires high rotational speed and high torque to work, it is prone to generate abnormal noises when contacting other gears during its working process. In some application scenarios, the gear for which the meshing deformation characteristics and meshing noise characteristics need to be obtained can be the driving gear, and the gear cooperating with it is the driven gear.

[0031] Specifically, the meshing deformation characteristics during the gear meshing process, that is, the deformation characteristics of the contact surface during the meshing process between the gear and other gears, can be collected by an image acquisition device. The meshing deformation characteristics during the meshing process can be the deformation characteristics of the entire process from the start to the end of meshing. The meshing deformation characteristics can include characteristics such as the deformation position, deformation amount, and deformation process of the contact surface, and can specifically reflect the deformation process and results during the meshing process.

[0032] Specifically, the meshing noise characteristics during the meshing process, that is, the relevant characteristics of the sound generated through contact during the meshing process between the gear and other gears, can be collected by a sound acquisition device. Similarly, the meshing noise characteristics can be the sound characteristics of the entire meshing process. The meshing noise characteristics can include static characteristics such as the loudness and pitch of the sound during the meshing process, or can also include dynamic change characteristics such as the loudness and pitch changing with time, without specific limitations.

[0033] S102: If the meshing noise feature does not meet the standard noise feature, determine the abnormal deformation position and the abnormal deformation amount according to the meshing deformation feature and the standard deformation feature; wherein the standard noise feature and the standard deformation feature are the noise feature and the deformation feature of the standard gear in the meshing process, respectively.

[0034] The standard gear and the gear for which the meshing deformation characteristics and meshing noise characteristics are obtained in this application are gears of the same model and have undergone the same processing, and they have similar structures and performance characteristics. However, the standard gear is a gear with relatively high precision or has been further processed, and the abnormal noise during operation is within a certain standard range.

[0035] After obtaining the noise characteristics of the meshing process of the standard gear, it can be used as a standard noise characteristic and stored. Among them, the standard noise characteristics can be presented in the form of a noise characteristic curve, which can reflect the static characteristics of the elements at each time point in the meshing process, and can also reflect the dynamic change characteristics of the elements in the entire meshing process. Among them, the noise characteristic curve can include a time-decibel curve, which reflects the relationship between the decibel and time of the noise in the entire meshing process, but of course it is not limited to this.

[0036] Similarly, after the deformation characteristics of the standard gear meshing process are obtained, they can be used as standard deformation characteristics and stored. In combination with the above content, the standard deformation characteristics can include the standard deformation position, standard deformation amount and standard deformation process of the contact surface.

[0037] It should be understood that if the meshing noise feature does not meet the standard noise feature, it means that the gear has produced an abnormal noise. In some embodiments, in order to make a more accurate judgment, the meshing noise feature can be judged to not meet the standard noise feature only when the difference between the meshing noise feature and the standard noise feature is greater than a preset difference value. In other embodiments, as long as the meshing noise feature and the standard noise feature are inconsistent, it is judged that the meshing noise feature does not meet the standard noise feature. For example, if the standard noise feature is represented by sound intensity and is characterized as being less than or equal to a preset decibel value, then when the decibel value corresponding to the meshing noise feature is greater than the preset decibel value, it can be considered that the meshing noise feature is inconsistent with the standard noise feature, the meshing noise feature does not meet the standard noise feature, and the gear has produced an abnormal noise.

[0038] When abnormal noises occur in the gear, generally, the accuracy of the contact surface of the gear is insufficient, resulting in some small defects, such as small protrusions. Due to the existence of these small defects, generally, the meshing deformation characteristics of the gear are inconsistent with the standard deformation characteristics, and thus abnormal noises are generated. Therefore, when abnormal noises occur in the gear, there are generally certain differences between the meshing deformation characteristics and the standard deformation characteristics. Conversely, based on these differences, the abnormal deformation position and the abnormal deformation amount can be determined. Among them, the abnormal deformation position and the abnormal deformation amount can be determined when the difference in deformation characteristics is greater than a certain degree.

[0039] S103: Determine the grinding position and the grinding amount of the gear according to the abnormal deformation position and the abnormal deformation amount, and grind the gear according to the grinding position and the grinding amount, so that the ground gear meets the standard noise characteristics during the meshing process.

[0040] It should be understood that after determining the abnormal deformation position and the abnormal deformation amount, in order to eliminate the abnormal deformation position and the abnormal deformation amount, the grinding position and the grinding amount of the gear can be determined. Among them, the grinding position and the grinding amount can be determined according to the operator's experience, or can be calculated by relevant computing devices and then determined intelligently, without specific limitations.

[0041] After determining the grinding position and the grinding amount, grind the gear according to the grinding position and the grinding amount to try to eliminate the abnormal deformation position and the abnormal deformation amount, so that the ground gear meets the standard noise characteristics during the meshing process.

[0042] Among them, after the gear is ground for the first time according to the grinding position and the grinding amount, it may still not meet the standard noise characteristics. At this time, it is necessary to further determine the grinding position and the grinding amount for further grinding, so that the ground gear finally meets the standard noise characteristics during the meshing process.

[0043] S104: Establish the corresponding relationship between the combination of the grinding position and the grinding amount and the meshing noise characteristics.

[0044] In the above steps, the gear will be ground according to the grinding position and the grinding amount, so that the ground gear finally meets the standard noise characteristics during the meshing process. When the ground gear meets the standard noise characteristics, there will be specific grinding position and grinding amount corresponding to it. This step establishes the corresponding relationship between the combination of the grinding position and the grinding amount and the meshing noise characteristics.

[0045] In summary, in this embodiment, the grinding position and the grinding amount are determined through noise comparison and deformation comparison. The determined grinding position and grinding amount can better eliminate the abnormal deformation of the gear, and the determined grinding position and grinding amount are relatively accurate, and the number of processes can be reduced. Moreover, after the corresponding relationship is determined, when the gears of the same subsequent process and model produce abnormal noises, if the meshing noise characteristics are similar, then the corresponding grinding position and grinding amount can be determined according to the meshing noise characteristics to precisely grind the gears, thereby effectively eliminating the abnormal noises and reducing the workload.

[0046] Figure 2 It is a schematic flowchart of another embodiment of the gear grinding parameter setting method provided by the present application.

[0047] Combined with Figure 2 , in some specific embodiments, the steps of obtaining the meshing deformation characteristics and the meshing noise characteristics of the gear during meshing include:

[0048] S201: Control the gear to mesh and work under different combinations of rotational speed and torque.

[0049] It should be understood that the working conditions of the gear involve different rotational speeds and torques. Therefore, in this embodiment, by controlling the gear to work under different combinations of rotational speed and torque, different working conditions of the gear can be simulated, so that the obtained meshing deformation characteristics and meshing noise characteristics are more in line with the actual application situation.

[0050] Combined with the above content, if the gear is a driving wheel, the rotational speed of the driving wheel can be controlled, and the torque of the driven wheel can be controlled to make the gear work under a specific combination of rotational speed and torque. Among them, the rotational speed in the combination of rotational speed and torque can be a rotational speed point or a rotational speed range; similarly, the torque can be a torque point or a torque range, without specific limitations.

[0051] S202: Obtain the meshing deformation characteristics and the meshing noise characteristics of the gear during meshing under each combination of rotational speed and torque.

[0052] Among them, the meshing deformation characteristics and the meshing noise characteristics during meshing under a specific combination of rotational speed and torque represent the deformation characteristics and noise characteristics of the gear under specific working conditions. At this time, there will be multiple sets of meshing deformation characteristics and meshing noise characteristics, which can more comprehensively reflect the deformation characteristics and noise characteristics of the vehicle under different working conditions.

[0053] Combined with the content of the above embodiment, in some specific embodiments, if the meshing noise characteristics do not meet the standard noise characteristics, the steps of determining the abnormal deformation position and the abnormal deformation amount according to the meshing deformation characteristics and the standard deformation characteristics include:

[0054] If the meshing noise characteristics corresponding to at least one set of rotational speed and torque combinations do not meet the corresponding standard noise characteristics, then based on the meshing deformation characteristics and standard deformation characteristics corresponding to the rotational speed and torque combinations that do not meet the standard noise characteristics, the abnormal deformation position and abnormal deformation amount are determined; wherein, different rotational speed and torque combinations correspond to different standard noise characteristics and standard deformation characteristics.

[0055] It should be understood that under different rotational speed and torque combinations, the standard gear generally undergoes different deformations, and thus corresponds to different standard deformation characteristics. At different rotational speeds and torques, the vehicle is in different working conditions, and when the vehicle is in different working conditions, the noise standards for vehicle components are generally different. Therefore, different rotational speed and torque combinations correspond to different standard noise characteristics.

[0056] Specifically, after obtaining the meshing noise characteristics corresponding to multiple sets of rotational speed and torque combinations, the meshing noise characteristics of each group are compared with the corresponding standard noise characteristics. In the comparison results, it is possible that the meshing noise characteristics of all groups meet the standard noise characteristics, it is possible that the meshing noise characteristics of some groups do not meet the standard noise characteristics, or it is possible that the meshing noise characteristics of all groups do not meet the standard noise characteristics. As long as the meshing noise characteristics corresponding to one set of rotational speed and torque combinations do not meet the corresponding standard noise characteristics, it indicates that the gear will produce abnormal noise under at least one working condition, and at this time, further processing is required.

[0057] In this embodiment, the abnormal deformation position and abnormal deformation amount are determined based on the meshing deformation characteristics and standard deformation characteristics corresponding to the rotational speed and torque combinations that do not meet the standard noise characteristics. Among them, the abnormal deformation position and abnormal deformation amount can be determined based on the meshing deformation characteristics and standard deformation characteristics corresponding to all rotational speed and torque combinations that do not meet the standard noise characteristics; or the abnormal deformation position and abnormal deformation amount can be determined based on the meshing deformation characteristics and standard deformation characteristics corresponding to some rotational speed and torque combinations that do not meet the standard noise characteristics. For example, now there are three combinations of rotational speed and torque. The meshing noise characteristics corresponding to the first and third combinations of rotational speed and torque do not meet the standard noise characteristics, and the meshing noise characteristics corresponding to the second combination of rotational speed and torque meet the standard noise characteristics. Then, at this time, the abnormal deformation position and abnormal deformation amount can be determined through the meshing deformation characteristics and standard noise characteristics corresponding to the first combination of rotational speed and torque, or the abnormal deformation position and abnormal deformation amount can be determined through the meshing deformation characteristics and standard noise characteristics corresponding to the third combination of rotational speed and torque, or the abnormal deformation position and abnormal deformation amount can be determined through the meshing deformation characteristics and standard noise characteristics corresponding to the first and third combinations of rotational speed and torque.

[0058] It should be understood that the abnormal deformation positions determined by different combinations of rotational speed and torque may be different, and at the same abnormal deformation position, the amount of deformation may also be different.

[0059] It should be understood that in this embodiment, the meshing deformation characteristics corresponding to the specific combination of rotational speed and torque are compared with the standard deformation characteristics, so as to determine the abnormal deformation position and the amount of abnormal deformation, and the determined abnormal deformation position and the amount of abnormal deformation are more in line with the actual rotational speed and torque conditions.

[0060] Figure 3 It is a schematic flowchart of another embodiment of the gear grinding parameter setting method provided by the present application.

[0061] Combined with Figure 3 , combined with the above embodiments, in some specific embodiments, if the meshing noise characteristics corresponding to at least one group of rotational speed and torque combinations do not meet the corresponding standard noise characteristics, then before the step of determining the abnormal deformation position and the amount of abnormal deformation according to the meshing deformation characteristics and the standard deformation characteristics corresponding to the rotational speed and torque combinations that do not meet the standard noise characteristics, it includes:

[0062] S301: Set the combination of the first rotational speed and the first torque and the combination of the second rotational speed and the second torque; wherein, the first rotational speed is greater than the second rotational speed, and the rotational speed difference between the two is greater than the preset rotational speed difference.

[0063] In this embodiment, at least two groups of combinations of rotational speed and torque are set, that is, the first combination corresponding to the first rotational speed and the first torque, and the second combination corresponding to the second rotational speed and the second torque.

[0064] Among them, the rotational speed and torque corresponding to the first combination and the second combination are different, and the rotational speed corresponding to the first combination is greater than the rotational speed corresponding to the second combination. At this time, the preset rotational speed difference can be a relatively large rotational speed difference, so that the first rotational speed is much greater than the second rotational speed. When the first rotational speed and the second rotational speed are rotational speed ranges, the rotational speed ranges corresponding to the first rotational speed and the second rotational speed do not overlap. At this time, the average value of the rotational speed range corresponding to the first rotational speed is greater than the average value of the rotational speed range corresponding to the second rotational speed, and the difference between the average values is greater than the preset rotational speed difference.

[0065] S302: Set the combination of the first rotational speed and the first torque corresponding to the first standard noise characteristic, and the combination of the second rotational speed and the second torque corresponding to the second standard noise characteristic; wherein, the average decibel value of the first standard noise characteristic is greater than the average decibel value of the second standard noise characteristic.

[0066] It should be understood that the first combination corresponds to a higher rotational speed and a higher vehicle speed, corresponding to the operating condition of the vehicle traveling at a higher speed. Conversely, the second combination corresponds to the operating condition of the vehicle traveling at a lower speed. When the vehicle is traveling at a higher speed, the user has a poor perception of the noise generated by the vehicle components. At this time, a larger noise can be allowed for the gear, that is, the gear can be required to have a lower noise standard characteristic. Conversely, when the vehicle is traveling at a lower speed, the user has a stronger perception of the noise generated by the vehicle components. At this time, only a smaller noise can be allowed for the gear, that is, the gear can be required to have a higher noise standard characteristic.

[0067] In this embodiment, the standard of the standard noise characteristic is measured by the average decibel value, that is, the standard of the standard noise characteristic is measured by the magnitude of the noise. At this time, the average decibel value of the first standard noise characteristic is greater than the average decibel value of the second standard noise characteristic, that is, the first standard noise characteristic corresponds to a lower standard, while the second standard noise characteristic corresponds to a higher standard.

[0068] Combining the above content, in some specific embodiments, if the meshing noise characteristics corresponding to at least one set of rotational speed and torque combinations do not meet the corresponding standard noise characteristics, the steps of determining the abnormal deformation position and the abnormal deformation amount according to the meshing deformation characteristics and the standard deformation characteristics corresponding to the rotational speed and torque combinations that do not meet the standard noise characteristics include:

[0069] If the meshing noise characteristics corresponding to the combination of the first rotational speed and the first torque do not meet the first standard noise characteristic, and the meshing noise characteristics corresponding to the combination of the second rotational speed and the second torque do not meet the second standard noise characteristic, then determine the abnormal deformation position and the abnormal deformation amount according to the meshing deformation characteristics and the corresponding standard deformation characteristics corresponding to the combination of the first rotational speed and the first torque.

[0070] At this time, if the meshing noise characteristics of the first combination do not meet the corresponding first standard noise characteristic, and the meshing noise characteristics corresponding to the second combination do not meet the corresponding second standard noise characteristic, determine the abnormal deformation position and the abnormal deformation amount according to the deformation characteristics corresponding to the first combination.

[0071] It should be understood that since the rotational speed corresponding to the first combination is higher, the standard corresponding to the first standard noise characteristic is lower. Therefore, when the first standard noise characteristic is not met, it means that the decibel value corresponding to the meshing noise characteristic of the gear at this time is higher. Conversely, when the second standard noise characteristic is not met, the decibel value corresponding to the meshing noise characteristic of the gear at this time is lower. At this time, the abnormal deformation position and the abnormal deformation amount are determined by the meshing deformation characteristics of the first combination with relatively serious corresponding noise and the corresponding standard noise characteristics, so that the determined grinding position and the grinding amount can better eliminate the abnormal noise generated by the gear under the operating condition corresponding to the first combination.

[0072] Figure 4 It is a schematic flowchart of another embodiment of the gear grinding parameter setting method provided by this application.

[0073] Combined with Figure 4 , in some specific embodiments, the steps of determining the grinding position and grinding amount of the gear according to the abnormal deformation position and abnormal deformation amount, and grinding the gear according to the grinding position and grinding amount so that the ground gear meets the standard noise characteristics during the meshing process, that is, the above step S103, include:

[0074] S401: Determine the initial grinding position and initial grinding amount of the gear according to the abnormal deformation position and abnormal deformation amount, and grind the gear according to the initial grinding position and initial grinding amount.

[0075] Whether the grinding position and grinding amount are obtained through manual experience or equipment calculation, the meshing noise characteristics of the ground gear may still not meet the standard noise characteristics. Therefore, an initial grinding position and initial grinding amount can be determined first, and then the initial grinding can be realized through the initial grinding position and initial grinding amount, so as to make further adjustments according to the actual situation in the subsequent process.

[0076] S402: Obtain the grinding meshing noise characteristics of the ground gear during the meshing process. If the grinding meshing noise characteristics do not meet the standard noise characteristics, determine the corrected grinding position and corrected grinding amount, and grind the gear according to the corrected grinding position and corrected grinding amount.

[0077] If the meshing noise characteristics of the ground gear do not meet the standard noise characteristics, it means that the gear needs to be further ground. At this time, further determine the corrected grinding position and corrected grinding amount, and then realize the corrected grinding based on the corrected grinding position and corrected grinding amount.

[0078] Among them, the process of determining the corrected grinding position and corrected grinding amount can also be determined according to experience or through equipment calculation. It can also be based on the corresponding meshing deformation characteristics after the previous grinding, and by comparing the meshing deformation characteristics with the standard deformation characteristics, further determine the corrected grinding position and corrected grinding amount.

[0079] S403: Repeat the previous step until the grinding meshing noise characteristics meet the standard noise characteristics.

[0080] That is, repeat the above step S402. At this time, obtain the grinding meshing noise characteristics of the ground gear during the meshing process. If the grinding meshing noise characteristics do not meet the standard noise characteristics, further determine the second corrected grinding position and corrected grinding amount, and grind the gear according to the corrected grinding position and corrected grinding amount, and so on in a cycle until the grinding meshing noise characteristics meet the standard noise characteristics.

[0081] Figure 5 It is a schematic flowchart of another embodiment of the gear grinding parameter setting method provided by the present application.

[0082] Combined with Figure 5 , in some specific embodiments, the step of establishing the correspondence between the combination of grinding positions and grinding amounts and the meshing noise characteristics, that is, the above step S104, includes:

[0083] S501: Obtain the meshing noise characteristics corresponding to the gear under different combinations of grinding positions and grinding amounts.

[0084] It should be understood that during the grinding process according to the grinding position and grinding amount, there may be multiple grinding processes, and at this time, there will be multiple combinations of grinding positions and grinding amounts. After each grinding, the meshing noise characteristics corresponding to the grinding position and grinding amount can be obtained.

[0085] S502: Establish the correspondence between different combinations of grinding positions and grinding amounts and the meshing noise characteristics.

[0086] At this time, under the initial meshing noise characteristics (i.e., the meshing noise characteristics before grinding), the correspondence between multiple sets of grinding positions and grinding amounts and the corresponding meshing noise characteristics can be established. For example, when detecting that the gear has an initial meshing noise, the following correspondence is generated during the subsequent grinding process: the combination of the first grinding position and grinding amount corresponds to the first meshing noise characteristic, the combination of the second grinding position and grinding amount corresponds to the second meshing noise characteristic, and the combination of the third grinding position and grinding amount corresponds to the third meshing noise characteristic. At this time, the meshing noise characteristic corresponding to the third set of grinding position and grinding amount combinations will meet the standard noise characteristic.

[0087] After the correspondence is established, when grinding other gears of the same type and the same processing process, if the standard noise characteristics corresponding to other gears are different, then the final grinding position and grinding amount can be determined according to the relationship between other meshing noise characteristics and the grinding position and grinding amount in the correspondence to meet the specific requirements in different scenarios. Combining the above example, if other gears meet the corresponding noise standard when they have the second meshing noise characteristic, then the grinding position and grinding amount can be directly determined as the second grinding position and the second grinding amount.

[0088] Figure 6 It is a schematic flowchart of another embodiment of the gear grinding parameter setting method provided by the present application.

[0089] Combined with Figure 6 , in some specific embodiments, the step of obtaining the meshing deformation characteristics of the gear during the meshing process includes:

[0090] S601: Magnify the contact surface of the gear during the meshing process through an image magnification device, and collect an image of the magnified contact surface during the meshing process through an image acquisition device.

[0091] Among them, magnifying the contact surface through the image magnification device facilitates the collected image to intuitively reflect the deformation characteristics of the contact surface.

[0092] S602: Analyze the image of the contact surface to obtain the meshing deformation characteristics of the gear during the meshing process.

[0093] After collecting the image of the contact surface, by analyzing it through an intelligent device, the meshing deformation characteristics during the meshing process can be directly obtained.

[0094] In some application scenarios, in order to reduce the processing volume of image processing and make the determined meshing deformation characteristics more in line with the actual situation, simulation analysis can be applied to obtain the meshing deformation characteristics of the simulation analysis. Among them, it is difficult to obtain some subtle abnormal deformations through simulation analysis, while the obtained deformation characteristics of the main body are relatively accurate. The meshing deformation characteristics obtained through image analysis can better reflect the subtle abnormal deformations. Therefore, the two can be combined, applying the main body deformation characteristics of the simulation analysis and the subtle abnormal deformations of the image analysis, and then obtaining the complete deformation characteristics, which can reduce the processing workload and make the obtained meshing deformation characteristics more accurate.
