Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically, to a testing device. Background Technology

[0002] In many fields, testing the meshing degree of gears is a crucial step, directly affecting gear performance and lifespan. Traditional testing methods mainly rely on transfer printing technology, which involves applying dye to the tooth grooves of one gear, then meshing and rotating that gear with another gear. The quality of meshing between the two gears is evaluated by observing the dye marks on the second test gear. The key to this testing method lies in the precise application of the dye and the accurate meshing between the gears.

[0003] Current devices for detecting gear meshing often employ independent and complex control systems to control the relative position between the dye storage component and the gear, as well as the rotation of the gear. For example, using electronic control to separately control the movement of the dye storage component and the rotation of the gear increases design and manufacturing complexity. Therefore, gear meshing detection devices in related technologies suffer from high complexity in their control methods. Summary of the Invention

[0004] The main objective of this invention is to provide a detection device to solve the problem of complex control methods in related technologies.

[0005] To achieve the above objectives, the present invention provides a detection device for detecting the degree of meshing between a first test gear and a second test gear. The detection device includes: a base; a rotating shaft rotatably mounted on the base and used to mount the first test gear, wherein rotation of the rotating shaft drives the first test gear to rotate synchronously; a dye storage assembly movably disposed relative to the first test gear, the dye storage assembly having a contact position and a disengagement position, wherein when the dye storage assembly is in the contact position, the dye storage assembly contacts the tooth groove of the first test gear, and when the dye storage assembly is in the disengagement position, the dye storage assembly separates from the first test gear and avoids the rotation of the first test gear; a drive unit disposed on the base; a first transmission assembly connected between the drive unit and the rotating shaft, such that the drive unit drives the rotating shaft to rotate via the first transmission assembly; and a second transmission assembly connected between the drive unit and the dye storage assembly, such that the drive unit drives the dye storage assembly to switch between the contact position and the disengagement position via the second transmission assembly.

[0006] Furthermore, the first transmission component is an intermittent transmission mechanism, and the second transmission component is a continuous transmission mechanism.

[0007] Furthermore, the drive unit includes a drive shaft, the first transmission assembly includes a first transmission disc disposed on the drive shaft, the first transmission disc being provided with partial transmission teeth, and the second transmission assembly includes a second transmission disc disposed on the drive shaft, the second transmission disc being provided with first full-circumference transmission teeth.

[0008] Furthermore, one of the partial transmission teeth and the first full-circumference transmission teeth is a straight tooth, and the other of the partial transmission teeth and the first full-circumference transmission teeth is a bevel tooth.

[0009] Furthermore, the second transmission assembly also includes a transmission mechanism, a rocker arm, a sliding sleeve, a moving rod, and a transmission rod. The sliding sleeve is slidably mounted on the rocker arm. One end of the moving rod is connected to the dye storage assembly, and the other end of the moving rod is hinged to the sliding sleeve. The transmission rod is hinged to the rocker arm, and the transmission mechanism is connected between the transmission rod and the second transmission disc.

[0010] Furthermore, the second transmission assembly also includes a guide portion having a guide hole through which the moving rod passes.

[0011] Furthermore, the swing arm includes a first rod and a second rod arranged at an angle, the swing axis of the swing arm is located at the connection between the first rod and the second rod, a sliding sleeve is fitted on the first rod, and the second rod is hinged to the transmission rod.

[0012] Furthermore, the transmission mechanism includes a third transmission disk and a fourth transmission disk that rotate coaxially. The third transmission disk is provided with a second full-circumference transmission tooth that meshes with the first full-circumference transmission tooth. The fourth transmission disk is provided with an eccentric shaft that is spaced apart from the rotation axis of the fourth transmission disk. The first end of the transmission rod is hinged to the rocker arm, and the second end of the transmission rod is hinged to the eccentric shaft.

[0013] Furthermore, the first transmission assembly also includes a fifth transmission disc, which is disposed on the rotating shaft and has a third full-circumference transmission tooth that meshes with the partial transmission tooth.

[0014] Furthermore, the dye storage assembly includes a contact and a reservoir. The contact is used to contact the tooth groove of the first test gear, and the reservoir is used to store dye. The reservoir and the contact have a release engagement state for releasing dye and a seal engagement state for sealing dye. The moving rod moves to switch the reservoir and the contact between the release engagement state and the seal engagement state.

[0015] Furthermore, the liquid storage unit includes a shell, a cover plate, a tension spring, and a guide post. The shell has an inner cavity and a release port communicating with the inner cavity. The cover plate is located inside the inner cavity and can seal the release port. One end of the guide post is connected to a contact element, and the other end of the guide post is inserted into the release port and connected to the cover plate. The tension spring is disposed on the guide post and connected between the cover plate and the contact element.

[0016] Furthermore, the contact element has a main channel and multiple sub-channels. The main channel is connected to the release port through a guide post. The sub-channels are set at an angle to the main channel. The first end of the sub-channel is connected to the main channel, and the second end of the sub-channel is connected to the outer surface of the contact element.

[0017] By applying the technical solution of this invention, the driving unit drives the rotating shaft to rotate via the first transmission assembly, thereby realizing the rotation of the first test gear. Simultaneously, the driving unit drives the dye storage assembly to switch between a contact position and a disengagement position via the second transmission assembly. This allows the dye storage assembly to contact the tooth grooves of the first test gear at appropriate times to apply dye, and then avoid the rotation of the first test gear, achieving uniform dyeing of the first test gear. This structure avoids using electronic control methods to separately control the rotation of the first test gear and the movement of the dye storage assembly, simplifying the control method and improving the reliability and ease of operation of the device. When the first test gear meshes with the second test gear, the degree of meshing between the two gears can be intuitively judged by the dye marks transferred onto the second test gear, without the need for complex control logic and additional control components. Therefore, the technical solution of this application can effectively solve the problem of complex control methods in related technologies. Attached Figure Description

[0036] like Figures 1 to 7 As shown, this application provides a detection device for detecting the degree of meshing between a first test gear 1 and a second test gear 2. An embodiment of the detection device includes: a base, a rotating shaft 10, a dye storage assembly 20, a drive unit 30, a first transmission assembly 40, and a second transmission assembly 50. The rotating shaft 10 is rotatably mounted on the base and used to mount the first test gear 1. Rotation of the rotating shaft 10 drives the first test gear 1 to rotate synchronously. The dye storage assembly 20 is movably disposed relative to the first test gear 1. The dye storage assembly 20 has a contact position and a disengagement position. When the dye storage assembly 20 is in the contact position... The dye storage component 20 contacts the tooth groove of the first test gear 1. When the dye storage component 20 is in the disengaged position, the dye storage component 20 separates from the first test gear 1 and avoids the rotation of the first test gear 1. The drive unit 30 is disposed on the base. The first transmission component 40 is connected between the drive unit 30 and the rotating shaft 10 so that the drive unit 30 drives the rotating shaft 10 to rotate through the first transmission component 40. The second transmission component 50 is connected between the drive unit 30 and the dye storage component 20 so that the drive unit 30 drives the dye storage component 20 to switch between the contact position and the disengaged position through the second transmission component 50.

[0037] Applying the technical solution of this embodiment, the drive unit 30 drives the rotating shaft 10 to rotate via the first transmission component 40, thereby realizing the rotation of the first test gear 1. Simultaneously, the drive unit 30 drives the dye storage component 20 to switch between a contact position and a disengagement position via the second transmission component 50. This allows the dye storage component to contact the tooth grooves of the first test gear 1 at appropriate times to apply dye, and then avoids the rotation of the first test gear 1, achieving uniform dyeing of the first test gear. This structure avoids using electronic control methods to separately control the rotation of the first test gear 1 and the movement of the dye storage component 20, simplifying the control method and improving the reliability and ease of operation of the device. When the first test gear 1 meshes with the second test gear 2, the degree of meshing between the two gears can be intuitively judged by the dye marks transferred onto the second test gear 2, without the need for complex control logic and additional control components. Therefore, the technical solution of this embodiment can effectively solve the problem of complex control methods in related technologies.

[0038] like Figures 1 to 7 As shown, the first transmission component 40 is an intermittent transmission mechanism, and the second transmission component 50 is a continuous transmission mechanism.

[0039] In this embodiment, this configuration enables precise control of the first test gear 1 by the drive unit 30 and continuous adjustment of the dye storage assembly 20. The intermittent transmission mechanism ensures that the shaft 10 of the first test gear 1 can rotate precisely according to the tooth pitch under the drive of the drive unit 30, thereby realizing the individual detection of each tooth slot of the first test gear 1; at the same time, the continuous transmission mechanism enables the dye storage assembly 20 to smoothly switch between the contact position and the disengagement position, ensuring that when the first test gear 1 is stationary, the dye can be accurately applied to the tooth slot to be tested, and when the first test gear 1 rotates, the dye storage assembly 20 is quickly removed to avoid interfering with the normal testing action of the gear. This combination of transmission methods not only simplifies the design of the control system and reduces costs, but also improves detection efficiency and accuracy, and can accurately determine the degree of meshing between the first test gear 1 and the second test gear 2.

[0040] like Figures 1 to 7 As shown, the drive unit 30 includes a drive shaft 31, the first transmission assembly 40 includes a first transmission disk 41 disposed on the drive shaft 31, the first transmission disk 41 is provided with partial transmission teeth, and the second transmission assembly 50 includes a second transmission disk 51 disposed on the drive shaft 31, the second transmission disk 51 is provided with first full-circumference transmission teeth.

[0041] In this embodiment, the drive unit 30 achieves precise control of the rotating shaft 10 and the dye storage assembly 20 via a first transmission disk 41 and a second transmission disk 51 on the drive shaft 31. The first transmission disk 41 is equipped with partial transmission teeth, while the second transmission disk 51 has a first full-circumference transmission tooth. This structural design allows the rotation of the drive shaft 31 to be transmitted to the rotating shaft 10 and the dye storage assembly 20 in time-sharing intervals. Within a specific rotation range of the drive shaft 31, the partial transmission teeth mesh with corresponding components on the rotating shaft 10, causing the first test gear 1 to rotate; simultaneously, the first full-circumference transmission teeth continuously interact with the second transmission assembly 50, guiding the dye storage assembly 20 to precisely switch between contact and disengagement positions, ensuring that the gear teeth are dyed without affecting the normal rotation of the first test gear 1. This innovative layout not only simplifies the operation of the detection device but also improves detection efficiency and accuracy, enabling convenient completion of the gear meshing degree detection task.

[0042] like Figures 1 to 7 As shown, one of the partial transmission teeth and the first full-circumference transmission teeth is a straight tooth, and the other of the partial transmission teeth and the first full-circumference transmission teeth is a bevel tooth. Specifically, this arrangement allows the dye storage assembly 20 to extend to the side of the first test gear 1, thereby optimizing the layout between the dye storage assembly 20 and the first test gear 1.

[0043] like Figures 1 to 7 As shown, the second transmission assembly 50 also includes a transmission mechanism 52, a rocker arm 53, a sliding sleeve 54, a moving rod 55, and a transmission rod 56. The sliding sleeve 54 is slidably disposed on the rocker arm 53. One end of the moving rod 55 is connected to the dye storage assembly 20, and the other end of the moving rod 55 is hinged to the sliding sleeve 54. The transmission rod 56 is hinged to the rocker arm 53, and the transmission mechanism 52 is connected between the transmission rod 56 and the second transmission disc 51.

[0044] In this embodiment, the second transmission assembly 50 includes a transmission mechanism 52, a rocker arm 53, a sliding sleeve 54, a moving rod 55, and a transmission rod 56. These components work together to achieve precise switching between the contact position and the disengagement position of the dye storage assembly 20. Specifically, the sliding sleeve 54 slides on the rocker arm 53 and, through a hinged connection with the moving rod 55, guides the dye storage assembly 20 to move along a predetermined path. The transmission rod 56 is hinged to the rocker arm 53 and connected to the second transmission disk 51 through the transmission mechanism 52. This interconnected structural design ensures that the power of the drive unit 30 is effectively transmitted to the dye storage assembly 20 during operation, enabling it to complete its movement under the drive of the drive unit 30.

[0045] like Figures 1 to 7 As shown, the second transmission assembly 50 also includes a guide portion 57, which has a guide hole 571 through which the moving rod 55 passes.

[0046] In this embodiment, the guide portion 57 further optimizes the movement path and stability of the dye storage assembly 20. The guide hole 571 serves to limit and guide the moving rod 55, ensuring precise movement of the dye storage assembly 20 between the contact and disengagement positions, avoiding deviation or shaking during movement, and enhancing the smoothness and reliability of the entire testing device. By constraining the moving rod 55 through the guide hole 571, the dye storage assembly 20 can move precisely along a preset trajectory, ensuring accurate alignment with the tooth groove of the first test gear 1 each time, improving testing accuracy and efficiency. Furthermore, the design of the guide portion 57 simplifies the structure of the second transmission assembly 50, eliminating the need for an additional complex positioning system, thus reducing manufacturing costs and maintenance difficulty.

[0047] like Figures 1 to 7 As shown, the swing arm 53 includes a first rod 531 and a second rod 532 arranged at an angle. The swing axis of the swing arm 53 is located at the connection between the first rod 531 and the second rod 532. The sliding sleeve 54 is sleeved on the first rod 531, and the second rod 532 is hinged to the transmission rod 56.

[0048] In this embodiment, the swing arm 53 includes a first rod 531 and a second rod 532 arranged at an angle. The swing axis of the swing arm 53 is located at the connection between the first rod 531 and the second rod 532. This structural design allows the swing arm 53 to swing effectively under the drive of the drive unit 30, thereby changing the position of the dye storage assembly 20. The sliding sleeve 54 is fitted on the first rod 531 and can slide freely along the first rod 531, while the second rod 532 is hinged to the transmission rod 56. This connection method ensures that the transmission rod 56 can make corresponding movements following the swing of the swing arm 53, and then, through the interaction between the transmission mechanism 52 and the second transmission disk 51, precisely control the switching between the contact position and the disengagement position of the dye storage assembly 20. Through this segmented swing arm design, the movement path of the dye storage assembly 20 is more stable and controllable, and the dye can be accurately applied to the designated tooth groove without affecting the normal rotation of the first test gear 1, thereby realizing the function of testing the degree of gear meshing. In addition, this design simplifies the transmission chain, making the entire detection device more compact and easier to maintain and adjust.

[0049] like Figures 1 to 7 As shown, the transmission mechanism 52 includes a third transmission disk 521 and a fourth transmission disk 522 that rotate coaxially. The third transmission disk 521 is provided with a second full-circumference transmission tooth, which meshes with the first full-circumference transmission tooth. The fourth transmission disk 522 is provided with an eccentric shaft, which is spaced apart from the rotation axis of the fourth transmission disk 522. The first end of the transmission rod 56 is hinged to the rocker arm 53, and the second end of the transmission rod 56 is hinged to the eccentric shaft.

[0050] In this embodiment, the transmission mechanism 52 includes a third transmission disk 521 and a fourth transmission disk 522 that rotate coaxially. The second full-circumference transmission teeth on the third transmission disk 521 mesh with the first full-circumference transmission teeth on the second transmission disk 51, ensuring that the continuous rotation of the drive shaft 31 can be continuously transmitted to the second transmission assembly 50. An eccentric shaft on the fourth transmission disk 522 is hinged to the second end of the transmission rod 56. When the drive shaft 31 rotates, the eccentric shaft drives the swing rod 53 to rotate around its swing axis through its connection with the transmission rod 56, thereby causing the sliding sleeve 54 to slide along the first rod body 531 of the swing rod 53. Since one end of the moving rod 55 is hinged to the sliding sleeve 54 and the other end is connected to the dye storage assembly 20, the sliding of the sliding sleeve 54 will cause the moving rod 55 to switch the dye storage assembly 20 between the contact position and the disengagement position. This transmission method effectively achieves precise control of the dye storage component 20, ensuring that the dye storage component 20 can accurately switch between contact and avoidance states when the first test gear 1 rotates, thereby achieving precise dyeing of the tooth grooves of the first test gear 1 without affecting the continuous rotation of the gear, thus improving the efficiency and accuracy of the detection process. Through the hinge between the transmission rod 56 and the eccentric shaft, the second transmission component 50 can convert the continuous rotation of the drive shaft 31 into the reciprocating motion of the dye storage component 20, further simplifying the control mechanism of the detection device, reducing the use of electrical control components, and lowering equipment costs and maintenance complexity. This design fully utilizes the precision and reliability of the structural transmission, achieving high efficiency and stability of the detection device during operation.

[0051] like Figures 1 to 7 As shown, the first transmission assembly 40 also includes a fifth transmission disk 42, which is disposed on the rotating shaft portion 10. The fifth transmission disk 42 has a third full-circumference transmission tooth that meshes with the partial transmission tooth.

[0052] In this embodiment, this design achieves precise transmission between the drive unit 30 and the rotating shaft 10, ensuring stable rotation of the first test gear 1 during the testing process. The engagement of the partial transmission teeth and the third full-circumference transmission teeth makes the rotation of the rotating shaft 10 smoother and more controllable, thereby improving the testing accuracy. When the drive unit 30 drives the rotating shaft 10 to rotate via the first transmission assembly 40, the third full-circumference transmission teeth on the fifth transmission disc 42 mesh with the partial transmission teeth on the drive shaft 31, ensuring efficient power transmission and enabling the first test gear 1 to rotate precisely according to the predetermined number of teeth. This transmission method not only simplifies the structure of the testing device but also improves testing efficiency and accuracy, allowing for a more intuitive and accurate assessment of gear contact quality when testing gear meshing.

[0053] like Figures 1 to 7As shown, the dye storage assembly 20 includes a contact 21 and a liquid storage section 22. The contact 21 is used to contact the tooth groove of the first test gear 1, and the liquid storage section 22 is used to store dye. The liquid storage section 22 and the contact 21 have a release engagement state for releasing dye and a sealing engagement state for sealing dye. The moving rod 55 moves to switch the liquid storage section 22 and the contact 21 between the release engagement state and the sealing engagement state.

[0054] In this embodiment, the movable rod 55 moves the liquid storage unit 22 and the contact member 21 to switch between a release engagement state and a sealing engagement state, ensuring that the dye can be accurately released into the tooth groove of the first test gear 1 when needed. During the rotation of the first test gear 1 and its engagement with the second test gear 2, the dye is effectively sealed to prevent leakage, ensuring the accuracy and reliability of the testing process. Through the interaction between the dye storage component 20 and the first test gear 1, precise control and management of the dye are achieved, optimizing the gear engagement degree detection process. When the contact member 21 contacts the tooth groove of the first test gear 1, the dye in the liquid storage unit 22 is released under the action of the contact member 21, thereby applying the dye to the first test gear 1 for subsequent engagement testing. As the movable rod 55 moves, the positional relationship between the contact member 21 and the liquid storage unit 22 changes, thereby controlling the release and sealing of the dye, ensuring accurate application of the dye and smooth operation of the testing process.

[0055] like Figures 1 to 7 As shown, the liquid storage section 22 includes a housing 221, a cover plate 222, a tension spring 223, and a guide post 224. The housing 221 has an inner cavity and a release port communicating with the inner cavity. The cover plate 222 is located in the inner cavity and can seal the release port. One end of the guide post 224 is connected to the contact member 21, and the other end of the guide post 224 is inserted into the release port and connected to the cover plate 222. The tension spring 223 is disposed on the guide post 224 and connected between the cover plate 222 and the contact member 21.

[0056] In this embodiment, the structural design of the liquid storage unit 22 enables controlled release and sealing of the dye. The housing 221 has an inner cavity and a release port communicating with it. The cover plate 222 is placed in the inner cavity and can seal the release port to prevent dye leakage. One end of the guide post 224 is connected to the contact member 21, and the other end is inserted into the release port and fixed to the cover plate 222, forming a dye release path. The tension spring 223 is mounted on the guide post 224, with its two ends connected to the cover plate 222 and the contact member 21, respectively. This structural arrangement allows the movement of the contact member 21 to directly drive the guide post 224, thereby controlling the opening or closing of the release port of the cover plate 222, achieving precise control and timely supply of dye. In the released engagement state, the cover plate 222 is pushed open, and the dye enters the contact member 21 through the release port and guide post 224. Then, the dye contacts the tooth groove of the first test gear 1 through the contact member 21, completing the dyeing process. In the sealed engagement state, the tension spring 223 ensures that the cover plate 222 seals the release port, preventing dye from flowing out and ensuring the stability of the dye storage assembly 20 in the non-operating state. Through the movement of the moving rod 55, the liquid storage section 22 and the contact member 21 can flexibly switch between the released engagement state and the sealed engagement state, ensuring accurate dye dispensing and reliable storage, thereby optimizing the meshing detection process between the first test gear 1 and the second test gear 2.

[0057] like Figures 1 to 7 As shown, the contact member 21 has a main channel 211 and multiple sub-channels 212. The main channel 211 is connected to the discharge port through the guide post 224. The sub-channels 212 are set at an angle to the main channel 211. The first end of the sub-channel 212 is connected to the main channel 211, and the second end of the sub-channel 212 is connected to the outer surface of the contact member 21.

[0058] In this embodiment, this structural design allows the dye to enter along the main channel 211 and then be evenly distributed to the outer surface of the contact member 21 through multiple sub-channels 212, thereby ensuring full contact with the tooth groove of the first test gear 1 and guaranteeing uniform dye application, thus improving the accuracy of the test results. When the contact member 21 contacts the tooth groove of the first test gear 1, the dye, through the dispersion effect of the sub-channels 212, can more meticulously fill every corner of the tooth groove, leaving obvious traces even in the smallest tooth gaps. This allows for a more accurate reflection of the meshing condition between the first test gear 1 and the second test gear 2 in subsequent meshing tests, including the integrity of the tooth surface contact and the presence or absence of tooth gaps. This multi-channel design not only enhances the dye release efficiency but also, through the adjustment of the layout of the sub-channels 212, can adapt to tooth grooves of different shapes and sizes, improving the applicability and flexibility of the detection device.

[0059] The detection method in this embodiment is as follows: The user rotates the drive unit 30 to switch the dye storage component 20 between the contact position and the disengagement position. When the drive unit 30 rotates one revolution, the first test gear 1 rotates one tooth, and the dye storage component 20 switches from the disengagement position to the contact position and then back to the disengagement position. On the one hand, one tooth groove is dyed, and on the other hand, the rotation of the first test gear 1 is avoided in the process, and the next tooth groove is aligned with the dye storage component 20. Then, the dyed first test gear 1 will transfer the dye to the second test gear 2. By transferring the mark on the second test gear 2, the degree of meshing between the first test gear 1 and the second test gear 2 can be determined.

[0060] In the description of this invention, it should be understood that "a plurality of" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing the invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0062] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
