Description

Technical Field

[0001] The present invention belongs to the technical field of dynamic deflection detection of couplings, and specifically refers to a device for detecting the dynamic deflection angle of a diaphragm coupling. Background Art

[0002] As a type of coupling, the diaphragm coupling not only has the function of transmitting rotational motion, but also has the function of compensating for the angular misalignment of the two coupled shafts because of the elastic diaphragm designed in its middle part, that is, the central axes of the two shafts do not coincide; even when the axis undergoes dynamic changes, a diaphragm coupling can also be used for connection; however, the compensation ability of the diaphragm coupling is limited, and at the same time, the compensation ability is an important technical parameter of the diaphragm coupling. It is very necessary to measure its dynamic deflection angle range during the stages of research and development, production or quality inspection. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a device for detecting the dynamic deflection angle of a diaphragm coupling; in this solution, when the diaphragm coupling is installed, the driving motor drives the yaw rotating shaft to rotate, and at the same time makes the arc-shaped sliding seat rotate and slide along the spiral slide rail. Under the guidance of the spiral slide rail, the lateral position of the arc-shaped sliding seat continuously moves, and then the diaphragm coupling is deflected by pushing the yaw rotating shaft; through the above solution design, the deformation amplitude of the diaphragm coupling can be fed back according to the rotation resistance of the yaw rotating shaft, and then the dynamic deflection angle range of the diaphragm coupling can be measured or detected.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a device for detecting the dynamic deflection angle of a diaphragm coupling, including a yaw detection mechanism, a sliding and transverse movement component and a bottom plate. A driving motor is provided on the bottom plate, the sliding and transverse movement component is provided on the bottom plate, and the yaw detection mechanism is provided on the sliding and transverse movement component; Further, the yaw detection mechanism includes a housing, a spiral slide rail, a swing arm assembly and an axial tightening assembly. The axial tightening assembly includes a yaw rotating shaft, and the output shaft of the driving motor and the yaw rotating shaft are connected by a diaphragm coupling.

[0005] The output shaft of the driving motor and the yaw rotating shaft are connected by a diaphragm coupling and both are rigid shafts. The position where deflection can occur is the diaphragm part of the diaphragm coupling. Therefore, by exploring the limit deflection angle of the yaw rotating shaft, the limit deflection angle of the diaphragm coupling can be fed back.

[0006] Preferably, the spiral slide rail is fixedly connected to the inner wall of the housing. The swing arm assembly includes an H-shaped swing arm and an arc-shaped sliding seat. A wide-width hinge disc is provided at the end of the yaw rotation shaft. The two ends of the H-shaped swing arm are respectively hinged to the arc-shaped sliding seat and the wide-width hinge disc. The arc-shaped sliding seat is slidably arranged on the spiral slide rail, and balls in rolling contact with the spiral slide rail are provided on the arc-shaped sliding seat.

[0007] When the yaw rotation shaft rotates, it will drive the arc-shaped sliding seat to slide along the spiral slide rail, so that the yaw rotation shaft will yaw relative to the initial axis through the support of the H-shaped swing arm, and the amplitude of the yaw is positively correlated with the sliding distance of the arc-shaped sliding seat on the spiral slide rail. Therefore, by controlling the rotation angle of the driving motor, the current yaw angle of the yaw rotation shaft can be fed back.

[0008] Furthermore, a flange portion is provided on the yaw rotation shaft, a stepped portion is provided at one end of the housing, an end frustum is provided in the stepped portion, and the axial tightening assembly further includes a conical spring, and the conical spring is arranged between the flange portion and the end frustum.

[0009] When the driving motor works, the positions of the driving motor and the housing are fixed. The elastic force of the conical spring can squeeze the yaw rotation shaft towards the inside of the diaphragm coupling, so as to prevent the diaphragm coupling from falling off the output shaft of the driving motor and prevent the yaw rotation shaft from falling off the diaphragm coupling.

[0010] Preferably, the yaw detection mechanism further includes a floating support assembly. The floating support assembly includes an inner ring and an outer ring. The inner ring is fixedly connected to the yaw rotation shaft. Outer cutting edges are evenly distributed annularly on the outside of the inner ring. The outer ring is rotatably arranged in the stepped portion. Inner cutting edges are evenly distributed annularly inside the outer ring. The number of the outer cutting edges and the inner cutting edges is equal. Floating springs are arranged between the outer cutting edges and the inner cutting edges.

[0011] The floating support assembly can provide floating support for the yaw rotation shaft when it rotates, which can not only ensure the coaxiality of the yaw rotation shaft and the diaphragm coupling in the initial state and facilitate clamping, but also enable the free end of the yaw rotation shaft to be fixed by the diaphragm coupling when the yaw rotation shaft yaws, and yaw is allowed at other positions.

[0012] As a further preference of the present invention, the swing arm assembly further includes a pin shaft one and a pin shaft two. A central hinge hole is provided on the wide-width hinge disc. The pin shaft one is arranged in the central hinge hole. One end of the H-shaped swing arm is hinged to the pin shaft one, and the other end of the H-shaped swing arm and the arc-shaped sliding seat are hinged through the pin shaft two.

[0013] Wherein, keys are provided on the output shaft of the driving motor and the yaw rotation shaft, and key grooves are provided on the diaphragm coupling. Through the connection of the keys, the synchronous rotation of the output shaft of the driving motor and the yaw rotation shaft can be ensured.

[0014] Due to the elastic force of the conical spring, between the output shaft of the driving motor, the diaphragm coupling, and the yaw rotating shaft, only a sliding insertion connection is required. Generally, it is not necessary to lock with a set screw. On the premise of ensuring stability, the operation steps are simplified and the operation efficiency is improved.

[0015] Further, the sliding transverse movement assembly includes a guide rail, a slider, and a slide plate. The guide rail is arranged on the bottom plate, the slider is slidably arranged on the guide rail, and the slide plate is arranged on the slider.

[0016] Preferably, a fixed seat is further arranged on the outer shell, and the outer shell is fixedly connected to the slide plate through the fixed seat.

[0017] Further, the sliding transverse movement assembly further includes a guide rail clamp. The guide rail clamp is arranged on the slide plate, and the relative position of the slider and the guide rail can be locked by clamping the guide rail through the guide rail clamp.

[0018] The slide plate can be locked and unlocked through the guide rail clamp.

[0019] The beneficial effects achieved by the present invention adopting the above structure are as follows: (1) The output shaft of the driving motor and the yaw rotating shaft are connected by a diaphragm coupling and both are rigid shafts. The position where deflection can occur is the diaphragm part of the diaphragm coupling. Therefore, by exploring the limit deflection angle of the yaw rotating shaft, the limit deflection angle of the diaphragm coupling can be reflected.

[0020] (2) When the yaw rotating shaft rotates, it will drive the arc-shaped sliding seat to slide along the spiral slide rail, so that the yaw rotating shaft deflects relative to the initial axis through the top support of the H-shaped swing arm, and the deflection amplitude is positively correlated with the sliding distance of the arc-shaped sliding seat on the spiral slide rail. Therefore, by the rotation angle of the driving motor, the current deflection angle of the yaw rotating shaft can be reflected.

[0021] (3) When the driving motor works, the positions of the driving motor and the outer shell are fixed. The elastic force of the conical spring can squeeze the yaw rotating shaft towards the inside of the diaphragm coupling, so as to prevent the diaphragm coupling from falling off the output shaft of the driving motor and prevent the yaw rotating shaft from falling out of the diaphragm coupling.

[0022] (4) Through the floating support assembly, the yaw rotating shaft can be floatingly supported when the yaw rotating shaft rotates, which can not only ensure the coaxiality of the yaw rotating shaft and the diaphragm coupling in the initial state and facilitate clamping; but also enable the free end of the yaw rotating shaft to be fixed by the diaphragm coupling when the yaw rotating shaft deflects, and deflection is allowed at other positions.

[0023] (5) Due to the elastic force of the conical spring, between the output shaft of the drive motor, the diaphragm coupling, and the yaw rotating shaft, a sliding insertion connection is sufficient. Generally, it is not necessary to lock it with a set screw. On the premise of ensuring stability, the operation steps are simplified and the operation efficiency is improved.

[0024] (6) The slide plate can be locked and unlocked by the guide rail clamp. BRIEF DESCRIPTION OF THE DRAWINGS

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0030] As Figures 1 to 9 shown, the present invention provides a dynamic deflection angle detection device for a diaphragm coupling, including a yaw detection mechanism 1, a sliding and transverse movement assembly 2 and a bottom plate 4. A driving motor 32 is provided on the bottom plate 4. The sliding and transverse movement assembly 2 is arranged on the bottom plate 4, and the yaw detection mechanism 1 is arranged on the sliding and transverse movement assembly 2; The yaw detection mechanism 1 includes an outer shell 5, a spiral slide rail 6, a swing arm assembly 7 and an axial tightening assembly 8. The axial tightening assembly 8 includes a yaw rotation shaft 17. The output shaft of the driving motor 32 and the yaw rotation shaft 17 are connected by a diaphragm coupling 3.

[0031] The output shaft of the drive motor 32 and the yaw rotating shaft 17 are connected by a diaphragm coupling 3, and both are rigid shafts. The position where deflection can occur is the diaphragm part of the diaphragm coupling 3. Therefore, by exploring the limit deflection angle of the yaw rotating shaft 17, the limit deflection angle of the diaphragm coupling 3 can be obtained.

[0032] The spiral slide rail 6 is fixedly connected to the inner wall of the housing 5. The swing arm assembly 7 includes an H-shaped swing arm 13 and an arc-shaped slide seat 14. A wide-width hinge disc 23 is provided at the end of the yaw rotating shaft 17. The two ends of the H-shaped swing arm 13 are respectively hinged to the arc-shaped slide seat 14 and the wide-width hinge disc 23. The arc-shaped slide seat 14 is slidably arranged on the spiral slide rail 6, and a ball 22 that is in rolling contact with the spiral slide rail 6 is provided on the arc-shaped slide seat 14.

[0033] When the yaw rotating shaft 17 rotates, it will drive the arc-shaped slide seat 14 to slide along the spiral slide rail 6, so that the yaw rotating shaft 17 deflects relative to the initial axis through the support of the H-shaped swing arm 13, and the deflection amplitude is positively correlated with the sliding distance of the arc-shaped slide seat 14 on the spiral slide rail 6. Therefore, by controlling the rotation angle of the drive motor 32, the current yaw angle of the yaw rotating shaft 17 can be obtained.

[0034] A flange portion 25 is provided on the yaw rotating shaft 17. A stepped portion 11 is provided at one end of the housing 5. An end frustum 12 is provided in the stepped portion 11. The axial tightening assembly 8 further includes a conical spring 18, and the conical spring 18 is arranged between the flange portion 25 and the end frustum 12.

[0035] When the drive motor 32 works, the positions of the drive motor 32 and the housing 5 are fixed. The elastic force of the conical spring 18 can squeeze the yaw rotating shaft 17 towards the inside of the diaphragm coupling 3, so as to prevent the diaphragm coupling 3 from falling off the output shaft of the drive motor 32 and prevent the yaw rotating shaft 17 from falling out of the diaphragm coupling 3.

[0036] The yaw detection mechanism 1 further includes a floating support assembly 9. The floating support assembly 9 includes an inner ring 19 and an outer ring 20. The inner ring 19 is fixedly connected to the yaw rotating shaft 17. Outer cutting edges 26 are evenly distributed in a ring on the outside of the inner ring 19. The outer ring 20 is rotatably arranged in the stepped portion 11. Inner cutting edges 27 are evenly distributed in a ring on the inside of the outer ring 20. The number of the outer cutting edges 26 and the inner cutting edges 27 is equal. Floating springs 21 are arranged between the outer cutting edges 26 and the inner cutting edges 27.

[0037] The floating support assembly 9 can provide floating support for the yaw rotating shaft 17 when the yaw rotating shaft 17 rotates. It can not only ensure the coaxiality of the yaw rotating shaft 17 and the diaphragm coupling 3 in the initial state and facilitate clamping, but also enable the free end of the yaw rotating shaft 17 to be fixed by the diaphragm coupling 3 when the yaw rotating shaft 17 deflects, and allow deflection at other positions.

[0038] The swing arm assembly 7 further includes a first pin shaft 15 and a second pin shaft 16. A central hinge hole 24 is provided on the wide hinge disc 23. The first pin shaft 15 is arranged in the central hinge hole 24. One end of the H-shaped swing arm 13 is hinged to the first pin shaft 15, and the other end of the H-shaped swing arm 13 and the arc-shaped sliding seat 14 are hinged through the second pin shaft 16.

[0039] Keys are provided on the output shaft of the driving motor 32 and the yaw rotating shaft 17. Key grooves are provided on the diaphragm coupling 3. Through the connection of the keys, it can be ensured that the output shaft of the driving motor 32 and the yaw rotating shaft 17 rotate synchronously.

[0040] Due to the elastic force of the conical spring 18, between the output shaft of the driving motor 32, the diaphragm coupling 3, and the yaw rotating shaft 17, only a sliding insertion connection is required. Generally, it is not necessary to lock with a set screw. On the premise of ensuring stability, the operation steps are simplified and the operation efficiency is improved.

[0041] The sliding and transverse movement assembly 2 includes a guide rail 28, a slider 29, and a sliding plate 30. The guide rail 28 is arranged on the bottom plate 4. The slider 29 is slidably arranged on the guide rail 28. The sliding plate 30 is arranged on the slider 29.

[0042] A fixed seat 10 is further provided on the housing 5. The housing 5 is fixedly connected to the sliding plate 30 through the fixed seat 10.

[0043] The sliding and transverse movement assembly 2 further includes a guide rail clamp 31. The guide rail clamp 31 is arranged on the sliding plate 30. By clamping the guide rail 28 with the guide rail clamp 31, the relative position of the slider 29 and the guide rail 28 can be locked.

[0044] The sliding plate 30 can be locked and unlocked through the guide rail clamp 31.

[0045] As Figure 10 shown, the horizontal axis represents the cumulative rotation angle of the driving motor 32 starting from the initial state, and the vertical axis represents the driving current of the driving motor 32. a, b, and c respectively represent the rotation angles corresponding to a certain value of the driving current when three different couplings are tested. Due to the existence of the H-shaped swing arm 13, the cumulative rotation angle of the driving motor 32 is positively correlated with the offset amplitude of the central axis of the yaw rotating shaft 17. For the same diaphragm coupling 3, the greater the deformation amplitude at the diaphragm, the greater the resistance to further deformation. That is to say, as the driving motor 32 rotates, the rotation resistance of the yaw rotating shaft 17 also increases.

[0046] As Figure 11As shown, the horizontal axis represents the cumulative rotation angle of the drive motor 32 starting from the initial state, and the vertical axis represents the torque reading of the sensor on the output shaft of the drive motor 32. A, B, and C respectively represent the rotation angles corresponding to a certain torque reading when three different couplings are being tested. Due to the presence of the H-shaped swing arm 13, the cumulative rotation angle of the drive motor 32 is positively correlated with the offset amplitude of the central axis of the yaw rotation shaft 17. For the same diaphragm coupling 3, the greater the deformation amplitude at the diaphragm, the greater the resistance to further deformation. That is to say, as the drive motor 32 rotates, the rotation resistance of the yaw rotation shaft 17 also increases accordingly.

[0047] As Figure 10 , 11 shown, the curve in the figure represents the relationship between the drive current of the drive motor 32 and the rotation angle. The inflection point of the curve represents the upper limit of the deformation of the diaphragm coupling 3. Before the inflection point, the elastic deformation of the diaphragm allows the two shafts to offset, and at this time the deformation resistance is small; after the inflection point, the deformation resistance increases sharply, indicating that it is difficult for the diaphragm coupling 3 to deform further, and there is a risk of damage if it continues to deform. Through the horizontal axis coordinate of the inflection point, the maximum allowable dynamic deflection angle of the diaphragm coupling 3 during normal operation can be calculated. In addition to the inflection point method, a specific vertical axis value can also be set, and by reading the horizontal axis coordinate corresponding to this value on the curve, the maximum allowable dynamic deflection angle of the diaphragm coupling 3 during normal operation can be calculated.

[0048] During specific use, first, the user needs to sleave one end of the diaphragm coupling 3 on the output shaft of the drive motor 32, and through the cooperation of the key and the keyway, make the diaphragm coupling 3 rotate synchronously with the output shaft of the drive motor 32. Then, by sliding the sliding plate 30, the yaw rotation shaft 17 is moved closer to the diaphragm coupling 3; the yaw rotation shaft 17 is supported by the floating support assembly 9 and is generally coaxially arranged with the diaphragm coupling 3. Therefore, as the sliding plate 30 slides, the yaw rotation shaft 17 will also enter the diaphragm coupling 3 and complete the connection through the cooperation of the key and the keyway.

[0049] After both ends of the diaphragm coupling 3 are respectively connected to the output shaft of the drive motor 32 and the yaw rotation shaft 17, the sliding plate 30 is locked by the guide rail clamp 31; generally, the elastic force of the conical spring 18 can prevent the diaphragm coupling 3 from falling off. According to the test requirements, if necessary, the two ends of the diaphragm coupling 3 can also be locked by set screws.

[0050] Subsequently, start the drive motor 32. The rotation speed of the drive motor 32 is relatively slow, about 5 - 7 r / min. The drive motor 32 drives the yaw rotation shaft 17 to rotate through the diaphragm coupling 3. When the yaw rotation shaft 17 rotates, it will drive the floating support assembly 9 and the swing arm assembly 7 to rotate as a whole. When the swing arm assembly 7 rotates, the arc-shaped slide block 14 will slide along the spiral slide rail 6 (the sliding resistance of the arc-shaped slide block 14 on the spiral slide rail 6 can be reduced by the balls 22). As the arc-shaped slide block 14 continuously approaches the drive motor 32 while rotating, with the support of the H-shaped swing arm 13, the yaw angle of the central axis of the yaw rotating shaft 17 will gradually increase, and the rotation angle of the main shaft of the drive motor 32 corresponds to the deflection angle of the yaw rotating shaft 17. Since the yaw rotating shaft 17 itself is made of rigid material, the fulcrum of the swing of the yaw rotating shaft 17 is at the diaphragm position of the diaphragm coupling 3.

[0051] According to the characteristics of the diaphragm coupling 3, the diaphragm part of the diaphragm coupling 3 can allow a certain degree of relative offset of the shafts at both ends through its own deformation. Moreover, the greater the deformation amplitude of the diaphragm part of the diaphragm coupling 3, the greater the resistance to further deformation. Therefore, as the offset amplitude of the yaw rotating shaft 17 increases, the sliding resistance of the arc-shaped slide block 14 will increase, and the rotation resistance of the yaw rotating shaft 17 will also increase.

[0052] Embodiment 1: When the rotation resistance of the yaw rotating shaft 17 increases, the drive current of the drive motor 32 will also increase. By monitoring the current of the drive motor 32, the relationship between the current and the rotation angle of the drive motor 32 can be obtained. The abscissa at the inflection point of the curve represents the maximum deflection amplitude allowed when the diaphragm coupling 3 works normally. At this time, the deflection angle of the yaw rotating shaft 17 can be calculated through the rotation angle of the drive motor 32.

[0053] Embodiment 2: A torque sensor can also be set on the output shaft of the drive motor 32. When the rotation resistance of the yaw rotating shaft 17 increases, the measured drive torque by the sensor will also increase. By monitoring the torque data, the relationship between the torque and the rotation angle of the drive motor 32 can be obtained. The abscissa at the inflection point of the curve represents the maximum deflection amplitude allowed when the diaphragm coupling 3 works normally. At this time, the deflection angle of the yaw rotating shaft 17 can be calculated through the rotation angle of the drive motor 32.

[0054] Embodiment 3: In addition to the inflection point method, a specific vertical axis value can also be set, and by reading the abscissa corresponding to this value on the curve, the maximum dynamic deflection angle allowed when the diaphragm coupling 3 works normally can be calculated.

[0055] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0056] The above describes the present invention and its embodiments. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
