[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0024] Embodiment 1: Combination Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a method for optimizing the performance detection of a gearbox, comprising: Step S1: providing an optimized gearbox, the optimized gearbox comprising a gearbox cover plate 10, an output gear 20, and a core gear set 30 connected to the output shaft of the motor; the core gear set 30 and the output gear 20 are unidirectional transmission, and a swing transmission assembly 40 is provided between the core gear set 30 and the gearbox cover plate 10 for driving the gearbox to swing; It should be noted that a unidirectional transmission is realized between the core gear set 30 and the output gear 20, ensuring that the rotation direction of the output gear 20 remains consistent regardless of whether the motor rotates forward or reversely; at the same time, a swing transmission assembly 40 is provided between the core gear set 30 and the gear box cover 10, and the swing function of the gear box is realized through the magnetic force of the special-shaped magnet 41 and the round iron block. When the core gear set 30 is running, it drives the gear box cover 10 to swing. The design purpose of this structure is to realize the swing function of the gear box while realizing power output, using the forward and reverse control of the motor, so as to meet the needs of multi-functional applications.
[0025] Step S2: Install a rotation direction detection component on the output gear 20 and a swing state detection component on the gear box cover 10 to obtain operating state data of the optimized gear box.
[0026] Step S3: Control the motor to run according to a predetermined forward and reverse sequence, so that the central shaft 31 rotates in the clockwise and counterclockwise directions respectively, drives the gear box to work, and makes the special-shaped magnet 41 drive the annular iron block 42 to realize the swing of the gear box cover 10; According to the preset forward and reverse sequences, the motor is controlled to operate so that the central shaft 31 rotates in the clockwise and counterclockwise directions respectively. Due to the special design of the core gear set 30, when the motor rotates forward, the core gear set 30 drives the gear box cover 10 to swing through the swing transmission assembly 40, while the output gear 20 maintains a fixed rotation direction; when the motor rotates reversely, the gear box cover 10 is also swung through the swing transmission assembly 40, and the rotation direction of the output gear 20 remains unchanged. By alternating the forward and reverse rotation of the motor, not only the operation of the gear box in different working modes is simulated, but also the consistency of the rotation direction of the output gear 20 and the effectiveness of the swing function of the gear box in the forward and reverse rotation conditions are verified.
[0027] Step S4: Collect the first detection data of the rotation direction detection component and the second detection data of the swing state detection component, analyze whether the rotation consistency of the output gear 20 and the swing amplitude and frequency of the gear box cover 10 meet the design requirements, and evaluate and optimize the performance of the gear box based on the analysis results.
[0028] Collect the first detection data obtained by the rotation direction detection component, that is, the rotation direction and speed information of the output gear 20 when the motor is rotating forward and reverse; at the same time, collect the second detection data obtained by the swing state detection component, that is, the swing amplitude and frequency data of the gear box cover 10 during operation. Analyze the first detection data to verify whether the rotation direction of the output gear 20 is always consistent under different motor rotation conditions to ensure the reliability of the transmission system. Analyze the second detection data, calculate the actual swing amplitude and frequency of the gear box cover 10, and compare them with the design requirements to evaluate whether the performance of the swing mechanism meets expectations. Based on the above analysis results, comprehensively evaluate and optimize the overall performance of the gearbox to determine whether it meets the design specifications and actual application requirements. If there is a situation that does not meet the design requirements, it is necessary to further analyze the cause, which may involve one-way bearing failure, gear meshing problems, or abnormal magnetic transmission components, etc., to provide a basis for subsequent improvements and optimizations.
[0029] The working principle of the present invention is as follows: an optimized gearbox is provided, a rotation direction detection component is installed on the output gear 20, a swing state detection component is installed on the gearbox cover 10, the motor is controlled to run according to a predetermined forward and reverse sequence, so that the central shaft 31 rotates in clockwise and counterclockwise directions respectively, drives the core gear set 30 to work, and realizes the swing of the gearbox cover 10 through the swing transmission component 40, collects the first detection data of the rotation direction detection component and the second detection data of the swing state detection component, respectively analyzes the rotation consistency of the output gear 20, and whether the swing amplitude and frequency of the gearbox cover 10 meet the design requirements, and evaluates the performance of the optimized gearbox according to the analysis results; the method simulates various working conditions of the optimized gearbox in actual work through targeted detection means, realizes real-time monitoring of the rotation direction of the output gear 20 and the swing state of the gearbox, verifies the transmission characteristics of the core gear set 30 and the working performance of the swing transmission component 40, so as to comprehensively evaluate the key performance of the gearbox.
[0030] In this embodiment, it is specifically described that step S4 specifically includes: Step S41: inputting the first detection data of the rotation direction detection component into the data processing module, recording the rotation direction of the output gear 20 when the motor is running forward and reverse, and generating time series data of the rotation direction of the output gear 20; The first detection data obtained by the rotation direction detection component is input into the data processing module. The first detection data contains the rotation direction information of the output gear 20 when the motor is running forward (clockwise) and reverse (counterclockwise). By recording these data, the time series data of the rotation direction of the output gear 20 is generated. This time series data reflects in detail the change of the rotation direction of the output gear 20 during the entire test process, providing a complete data basis for subsequent analysis.
[0031] Step S42: Analyze the time series data, extract the rotation direction information of the output gear 20 when the motor rotates forward and reverse respectively, determine whether the rotation direction of the output gear 20 remains consistent under different motor rotation conditions, and verify the consistency of the rotation direction of the output gear 20.
[0032] The time series data generated in step S41 is analyzed. The data processing module extracts the rotation direction information of the output gear 20 when the motor rotates forward and reverse respectively. Through comparative analysis, it is determined whether the rotation direction of the output gear 20 remains consistent under different rotation conditions of the motor. This step is intended to verify the consistency of the rotation direction of the output gear 20 and ensure that the single-rotation transmission mechanism of the optimized gearbox works properly, that is, whether the motor rotates forward or reverse, the output gear 20 always maintains the same rotation direction.
[0033] Step S43: Input the second detection data of the swing state detection component into the data processing module, calculate the swing amplitude and swing frequency of the gear box cover 10, and generate a swing parameter curve of the gear box cover 10. The swing parameter curve intuitively displays the swing characteristics of the gear box cover 10 and reflects the actual working state of the swing transmission component 40.
[0034] Step S44: comparing the swing parameter curve with the swing parameter range required by the design, evaluating the swing amplitude and swing frequency of the gear box cover plate 10, and detecting whether there is a swing abnormality or a deviation exceeding the limit; The swing parameter curve generated in step S43 is compared with the swing parameter range required by the design. By evaluating the actual swing amplitude and swing frequency of the gearbox cover 10, it is detected whether there is a swing abnormality or a deviation beyond the allowable range. For example, the design requires that the swing amplitude is within a specific range and the swing frequency meets the set value. If the actual detection result exceeds these ranges, it may indicate that there is an abnormality in the swing mechanism, ensuring that the performance of the swing transmission assembly 40 meets the design specifications and the reliability of the gearbox in actual application.
[0035] Step S45: Combined with the analysis results of the rotational consistency of the output gear 20 and the evaluation results of the swing parameters of the gear box cover 10, comprehensively judge whether the performance of the optimized gear box meets the design requirements. If so, it is judged as a qualified product; if not, it is judged as an unqualified product, and the cause of the abnormality is analyzed.
[0036] If there is an abnormality, further diagnosis of possible fault causes is required, such as: One-way bearing failure: causes abnormal transmission direction or gear failure.
[0037] Poor gear meshing: causes the output gear 20 to rotate unstably or swing abnormally.
[0038] Abnormality of magnetic transmission assembly: The special-shaped magnet 41 or the round iron block is damaged, resulting in failure of the swing function.
[0039] In this embodiment, it is specifically explained that step S43 specifically includes: Step S431: transmitting the second detection data of the swing state detection component to the data processing module, the second detection data being a real-time displacement signal of the gear box cover plate 10 during the swinging process; The second detection data obtained by the swing state detection component is transmitted to the data processing module. The second detection data is a real-time displacement signal of the gear box cover 10 during the swing process, reflecting the position change of the gear box cover 10 at each time point. By inputting these real-time displacement signals into the data processing module, basic data is provided for subsequent data analysis and calculation.
[0040] Step S432: preprocessing the real-time displacement signal, using a filtering algorithm to eliminate noise and interference, and obtaining effective displacement data of the gear box cover 10; The acquired real-time displacement signal is preprocessed. Since the signal may be affected by environmental noise and equipment interference during the actual measurement process, a filtering algorithm (such as a low-pass filter, a Kalman filter, etc.) is used to process the signal to eliminate noise and interference and extract effective displacement information. After filtering, the effective displacement data obtained more accurately reflects the actual swing state of the gearbox cover 10.
[0041] Step S433: Based on the effective displacement data, the instantaneous swing amplitude of the gear box cover plate 10 is calculated using the time-displacement relationship, the displacement peak and valley values are extracted, and the maximum, minimum and average values of the swing amplitude are calculated; Based on the effective displacement data obtained, the instantaneous swing amplitude of the gearbox cover 10 is calculated using the time-displacement relationship. Specifically, by analyzing the displacement data, the peak value (maximum displacement) and valley value (minimum displacement) of the signal are extracted, and the swing amplitude in each cycle is calculated. Subsequently, the maximum, minimum and average values of the swing amplitude are statistically calculated to fully understand the swing characteristics and consistency of the gearbox cover 10. These parameters can reflect the performance stability of the swing component.
[0042] Step S434: performing frequency domain analysis on the effective displacement data, extracting the swing frequency of the gear box cover 10 using a fast Fourier transform method, and generating a frequency spectrum; The effective displacement data is analyzed in the frequency domain. The fast Fourier transform (FFT) method is used to convert the displacement signal in the time domain to the frequency domain to extract the swing frequency of the gearbox cover 10. By generating a spectrum diagram, the amplitude of each frequency component in the signal can be intuitively observed, and the main swing frequency and possible harmonic or noise interference can be determined. Frequency domain analysis helps to evaluate the dynamic performance of the swing mechanism and detect abnormal conditions such as resonance or frequency offset.
[0043] Step S435: Integrate the data results of the swing amplitude and the swing frequency to generate a swing parameter curve of the gear box cover 10, including a swing amplitude-time curve and a swing frequency-time curve, to graphically display the swing characteristics of the gear box cover 10.
[0044] The swing amplitude data obtained in step S433 and the swing frequency data obtained in step S434 are integrated to generate a swing parameter curve of the gearbox cover plate 10. The swing parameter curve includes a swing amplitude-time curve and a swing frequency-time curve, which graphically and intuitively display the swing characteristics of the gearbox cover plate 10. By observing these curves, the swing behavior of the gearbox cover plate 10 can be fully understood, possible abnormal changes can be discovered, and an important basis can be provided for performance evaluation and fault diagnosis.
[0045] In this embodiment, it is further explained that after step S4, the following steps are further included: Step S5: According to the performance evaluation results of the optimized gearbox, the test conditions, test conditions and corresponding classifications are recorded, a performance test report is generated, and improvement suggestions are put forward for the abnormal causes of unqualified products.
[0046] According to the performance evaluation results of the optimized gearbox in the previous steps, record the test conditions, test data and corresponding classification. Specifically, record in detail the equipment used in the test process, environmental conditions, motor operating parameters and other information. Subsequently, generate a performance test report, which includes the test method, data analysis results, performance evaluation conclusions and other contents. For gearboxes that are judged to be unqualified, further analyze the causes of the abnormalities, which may involve one-way bearing failure, poor gear meshing, failure of magnetic transmission components, etc., and put forward targeted improvement suggestions. The purpose of this step is to comprehensively summarize and archive the test process and results, provide a basis for product quality control and subsequent improvements, and ensure that the optimized gearbox has reliable performance and quality in actual applications.
[0047] In this embodiment, as a preferred solution, the rotation direction detection component is a photoelectric encoder, which is used to detect the rotation direction and speed of the output gear 20 in real time.
[0048] In this embodiment, in order to accurately and in real time detect the rotation direction and speed of the output gear 20, a photoelectric encoder is selected as a rotation direction detection component. The photoelectric encoder is installed on the output gear 20, and uses photoelectric sensing technology to convert mechanical rotational motion into electrical signals, so that the rotation direction and speed information of the output gear 20 can be accurately obtained. In the performance detection method of the gear box, the real-time data provided by the photoelectric encoder is input into the data processing module to analyze the rotation consistency of the output gear 20 when the motor is in forward and reverse rotation.
[0049] In this embodiment, as a preferred solution, the swing state detection component is a laser displacement sensor, which is used for non-contact detection of the swing amplitude and frequency of the gear box cover 10.
[0050] It should be noted that in order to avoid physical interference with the swing of the gearbox cover 10, a laser displacement sensor is selected as the swing state detection component. The laser displacement sensor is installed in a fixed position, aimed at a specific part of the gearbox cover 10, and uses the laser ranging principle to non-contactly detect the real-time displacement change of the gearbox cover 10 during the swing process. The sensor can capture tiny displacements with high precision and high response speed, and input the second detection data into the data processing module.
[0051] Embodiment 2: Combination Figures 3 to 5 As shown, the present invention also provides a design for optimizing the gearbox, specifically including a gearbox cover 10, an output gear 20, and a core gear set 30 connected to the motor output shaft, and a swing transmission assembly 40 is arranged between the core gear set 30 and the gearbox cover 10.
[0052] In this embodiment, it is further explained that the optimized gearbox also includes a driving gear set 50 arranged adjacent to the core gear set 30, and the driving gear set 50 is meshed with the output gear 20; the core gear set 30 includes a central shaft 31 connected to the output shaft of the motor, and a first gear 32 and a second gear 33 are sequentially provided on the central shaft 31. The first gear 32 is meshed with the driving gear set 50, and the second gear 33 is meshed with the driving gear set 50 through the idler gear 60.
[0053] In this embodiment, it is specifically described that the driving gear set 50 is provided with a third gear 51 and a fourth gear 52 above and below, and the third gear 51 and the fourth gear 52 are spaced apart to form a spacing space 53; the third gear 51 is meshed with the first gear 32 of the core gear set 30, and the second gear 33 is aligned with the spacing space 53; wherein the fourth gear 52 and the second gear 33 are respectively meshed with the idler gear 60, so that the second gear 33 and the driving gear set 50 are indirectly transmitted.
[0054] The working principle of this optimized gearbox is as follows: the above is the internal structure of the optimized gearbox, and its core lies in the optimized design of the transmission scheme between the core gear set 30 and the output gear 20. The motor is divided into two modes: forward rotation and reverse rotation: when the motor rotates forward (clockwise), the first gear 32 does not rotate, and the second gear 33 rotates clockwise, thereby driving the idler gear 60 to rotate counterclockwise, and the idler gear 60 drives the fourth gear 52 to rotate clockwise, and the fourth gear 52 drives the output gear 20 to rotate counterclockwise.
[0055] When the motor rotates reversely (counterclockwise), the first gear 32 rotates counterclockwise, the second gear 33 does not rotate, the first gear 32 directly drives the core gear set 30 to rotate clockwise (because the two are meshed), and the core gear set 30 drives the output gear 20 to rotate counterclockwise.
[0056] Therefore, it can be known that no matter the motor rotates forward or reverse, the output gear 20 rotates counterclockwise, and the direction of rotation of the motor does not affect the final rotation direction of the output gear 20. Through this design, no matter the motor rotates forward or reverse, the output gear 20 can rotate in a constant direction, realizing the function of unidirectional transmission.
[0057] In this embodiment, a counterclockwise one-way bearing is provided between the first gear 32 and the center shaft 31, and a clockwise one-way bearing is provided between the second gear 33 and the center shaft 31; the swing transmission assembly 40 includes a special-shaped magnet 41 arranged at the front end of the center shaft 31, a circular iron block 42 is fixedly provided on the gear box cover plate 10, a sliding bearing 43 is provided in the inner hole of the circular iron block 42, and the center shaft 31 passes through the sliding bearing 43; the special-shaped magnet 41 and the circular iron block 42 are arranged relative to each other to realize the swing of the gear box through magnetic attraction.
[0058] It should be noted that the special-shaped magnet 41 is arranged relative to the circular iron block 42. By utilizing the effect of magnetic attraction, when the central shaft 31 rotates, the special-shaped magnet 41 drives the circular iron block 42 to move relative to the central shaft 31, thereby driving the gear box cover 10 to swing around the central shaft 31. Since the central shaft 31 is eccentrically mounted on the gear box cover 10, this magnetically coupled swinging mode realizes the swing arm function of the gear box. During the swinging process, if an obstacle is encountered, the magnetic transmission allows the gear box cover 10 to passively stop swinging, thereby avoiding mechanical damage and improving the safety and reliability of the device.
[0059] The special-shaped magnet 41 and the circular iron block are arranged relative to each other, so that when the central axis 31 drives the special-shaped magnet 41 to rotate, the special-shaped magnet 41 can drive the circular iron block to rotate through magnetic attraction, and the rotation of the circular iron block drives the gear box cover 10 to swing around the central axis 31 (the central axis 31 is arranged at an eccentric position of the gear box cover 10), thereby realizing the swinging operation of the gear box; it should be understood that the swinging here refers to the swinging of the gear box around the node of the central axis 31.
[0060] Then, as mentioned earlier, the motor has two states of forward rotation and reverse rotation, so the motor realizes the swinging work of the gearbox by alternating between forward rotation and reverse rotation (swinging can be understood as a swinging forward and backward movement).
[0061] Therefore, the technical solution of the present invention is to realize the swing arm action by the forward and reverse rotation of the motor, but at the same time it does not affect the transmission direction of the gear box, that is, this solution realizes the power output of the gear set and the swing work of the gear box at the same time through a group of motors; design a function that relies on a single motor to realize the output shaft work while adding the swing arm action, and ensure that the rotation direction of the work remains unchanged when performing the external swing action, and if an obstacle is encountered while swinging the arm, it will not get stuck or push the obstacle, and it can also meet the requirements of working at different speeds. This technology belongs to a gear transmission device and can be applied to multiple fields and occasions.
[0062] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
