[0038] See also Figures 1 to 8 As shown, according to an embodiment of the present application, a bevel gear transmission mechanism is provided, including a base 10 , a transmission assembly 20 and a first adjustment pad 31 .

[0039] Among them, a first installation cavity 101 is provided in the base 10, and the transmission assembly 20 is provided in the first installation cavity 101. The transmission assembly 20 includes a rotating shaft 21, a first bevel gear 22 and a second bevel gear 23; the first bevel gear 22 is sleeved on the rotating shaft 21, and the second bevel gear 23 is installed on the outer periphery of the rotating shaft 21. There is a first gap 41 between the end faces of the first bevel gear 22 and the second bevel gear 23, the first bevel gear 22 is meshed with the input gear 61, and the second bevel gear 23 is meshed with the output gear 62; the first adjustment pad 31 includes multiple specifications, and the thickness of the first adjustment pad 31 of each specification is different. The first adjustment pads 31 of multiple specifications can be selectively embedded in the first gap 41, the first adjustment pad 31 is arranged in a ring shape, and the first adjustment pad 31 includes a plurality of segmented arc segments 311, and each arc segment 311 is detachably embedded in the first gap 41.

[0040] Specifically, in the existing bevel gear transmission mechanism, the first bevel gear 22 and the second bevel gear 23 are connected by multiple pins, and the multiple pins are used to transmit power, and multiple first fixing members 51 are connected between the first bevel gear 22 and the second bevel gear 23, and the multiple first fixing members 51 are used to fix the first bevel gear 22 and the second bevel gear 23. The first fixing members 51 are screws. When it is necessary to adjust the first gap 41 between the first bevel gear 22 and the second bevel gear 23, the multiple screws and the multiple pins are first disassembled, and then the first bevel gear 22 and the second bevel gear 23 are separated. At this time, the first adjustment pad 31 embedded in the first gap 41 can be taken out of the first gap 41, and then the first gap 41 is adjusted. After adjusting the first gap 41, the first adjustment pad 31, the pins and the screws need to be reassembled, which makes the assembly process complicated and time-consuming and labor-intensive.

[0041] In the present embodiment, since the first adjustment pad 31 is arranged in an annular shape and includes a plurality of arc segments 311 arranged in segments, each arc segment 311 is detachably embedded in the first gap 41; that is, since the first adjustment pad 31 is arranged in segments, each arc segment 311 can be directly embedded in the first gap 41. When the bevel gear transmission structure needs to adjust the first gap 41, it is not necessary to separate the first bevel gear 22 and the second bevel gear 23, and the first adjustment pad 31 can be taken out of the first gap 41 or embedded in the first gap 41. In addition, in the present embodiment, the first adjustment pad 31 includes a plurality of specifications of different thicknesses. After the first gap 41 is adjusted to a predetermined size, the first adjustment pad 31 having the same thickness as the width of the first gap 41 can be directly embedded in the first gap 41, so that the width of the first gap 41 can be adjusted, thereby greatly improving the adjustment efficiency of the first gap 41.

[0042] It is worth mentioning that in this embodiment, the first bevel gear 22 is sleeved on the outer circumference of the rotating shaft 21, the second bevel gear 23 is sleeved on the outer circle of the first bevel gear 22, and a first gap 41 is formed between the end surface of the second bevel gear 23 close to the first bevel gear 22 and the first bevel gear 22. Of course, in some other embodiments, the first bevel gear 22 and the second bevel gear 23 are both sleeved on the outer circumference of the rotating shaft 21, and the first gap 41 is located between the two opposite end surfaces of the first bevel gear 22 and the second bevel gear 23. In addition, as shown in the attached Figure 1As shown, the bevel gear transmission mechanism in this embodiment further includes a first thrust bearing 81 and a second thrust bearing 82, which are respectively sleeved at both ends of the rotating shaft 21, so that the first bevel gear 22 is fixed on the rotating shaft 21, that is, the first thrust bearing 81 and the second thrust bearing 82 are respectively stopped at both ends of the first bevel gear 22 and the rotating shaft 21, thereby preventing the first bevel gear 22 from moving in the axial direction. In this embodiment, a fixing nut 83 is also sleeved on the rotating shaft 21, and the fixing nut 83 abuts against the second thrust bearing 82, and the fixing nut 83 contacts the inner ring of the second thrust bearing 82, thereby preventing the second thrust bearing 82 from loosening on the rotating shaft 21.

[0043] Furthermore, the first bevel gear 22 and the second bevel gear 23 are connected by a first fixing member 51, and a first adjusting hole 222 is provided on the first bevel gear 22, and the axial direction of the first adjusting hole 222 is the same as the axial direction of the rotating shaft 21; the bevel gear transmission mechanism also includes an adjusting member, which is detachably penetrated through the first adjusting hole 222 and abuts against the second bevel gear 23, and the adjusting member cooperates with the first fixing member 51 to adjust the size of the first gap 41.

[0044] Specifically, when adjusting the first gap 41, the adjusting member passes through the first adjusting hole 222, the adjusting member abuts against the second bevel gear 23, and an external force is applied to the adjusting member, so that the second bevel gear 23 moves in a direction away from the first bevel gear 22, so that the first gap 41 increases. After adjusting the first gap 41, the size of the first gap 41 is measured, and the corresponding first adjustment pad 31 is rotated according to the size of the first gap 41, and the first adjustment pad 31 is embedded in the first gap 41, and finally the adjusting member is disassembled. In this embodiment, the adjusting member can be a screw or a screw. As shown in the attached figure Figure 4 As shown, the first bevel gear 22 is provided with a plurality of first adjustment holes 222 arranged at intervals, and the plurality of first adjustment holes 222 can be used to adjust the size of the first gap 41 by passing through a plurality of adjustment members. In addition, in the present embodiment, the first bevel gear 22 and the second bevel gear 23 are connected by a first fixing member 51. When adjusting the first gap 41, the first fixing member 51 needs to be loosened, and then the first gap 41 is adjusted by the adjustment member. It is worth mentioning that loosening the first fixing member 51 does not mean removing the first fixing member 51. After loosening the first fixing member 51, a movable gap can be formed between the first bevel gear 22 and the second bevel gear 23, so as to facilitate the adjustment of the first gap 41. At the same time, when the adjustment member adjusts the first gap 41, the first fixing member 51 can play a certain limiting role on the width of the first gap 41, thereby preventing the first gap 41 from being too large. When the first gap 41 is too large, the width of the first gap 41 can be reduced by tightening the first fixing member 51.

[0045] When the second bevel gear 23 is meshed with the output gear 62, there may be a certain gap at the meshing point between the second bevel gear 23 and the output gear 62. If the gap is too large, it will affect the transmission efficiency. In serious cases, it may cause the second bevel gear 23 to be disengaged from the output gear 62. If the gap is small, it may cause interference between the transmission assembly 20 and the second bevel gear 23. In this embodiment, the size of the gap between the second bevel gear 23 and the output gear 62 can be adjusted by adjusting the size of the first gap 41, that is, when the second bevel gear 23 moves in a direction away from the first bevel gear 22, the second bevel gear 23 moves in a direction close to the output gear 62, thereby reducing the gap between the second bevel gear 23 and the output gear 62; and when the first fixing member 51 is tightened, the second bevel gear 23 moves in a direction close to the first bevel gear 22, and the first gap 41 is reduced, so that the gap between the second bevel gear 23 and the output gear 62 increases. In this embodiment, when adjusting the gap between the second bevel gear 23 and the output gear 62 , there is no need to disassemble the first bevel gear 22 and the second bevel gear 23 , so the assembly efficiency of the bevel gear transmission mechanism can be effectively improved.

[0046] In addition, a plurality of avoidance holes 312 are provided on the arc segment 311, and the avoidance holes 312 can be used to avoid the adjustment member and the first fixing member 51. In other words, in order to prevent the arc segment 311 from interfering with the first fixing member 51 or the adjustment member when the arc segment 311 is inserted into the first avoidance hole 312, the avoidance holes 312 are provided on the arc segment 311 in this embodiment.

[0047] In this embodiment, since the first adjustment pad 31 is a plurality of arc segments 311 arranged in sections, when the arc segment 311 is embedded in the first gap 41, the arc segment 311 may be affected by other external forces, which eventually causes the arc segment 311 to be separated from the first gap 41. In order to avoid the above situation, the bevel gear transmission mechanism in this embodiment also includes a limiting portion 70, which is arranged on one of the first bevel gear 22 and the second bevel gear 23, and the limiting portion 70 has a first position for closing the first gap 41 so that the first adjustment pad 31 is limited in the first gap 41, and a second position for opening the first gap 41 adjustment pad. That is, after the arc segments 311 are all embedded in the first gap 41, the limiting portion 70 is adjusted to the first position so that the arc segment 311 is limited in the first gap 41; and when the first adjustment pad 31 needs to be taken out from the first gap 41, the limiting portion 70 can be moved to the second position to facilitate the arc segment 311 to be taken out from the first gap 41.

[0048] As attached Figure 1As shown, the limiting portion 70 includes a limiting sleeve 71 and a stopper 72. The limiting sleeve 71 is sleeved on the outer periphery of the second bevel gear 23. The stopper 72 passes through the limiting sleeve 71 and abuts against the outer periphery of the second bevel gear 23 so that the limiting sleeve 71 is fixed on the outer periphery of the second bevel gear 23. The limiting sleeve 71 can reciprocate along the axial direction of the second bevel gear 23 to switch between the first position and the second position.

[0049] Specifically, when the first gap 41 needs to be adjusted, the stopper 72 is first loosened to allow the limiting sleeve 71 to move in the axial direction of the second bevel gear 23, and then the limiting sleeve 71 is moved to the second position. At this time, the first gap 41 is open, and the first adjustment pad 31 in the first gap 41 can be taken out. Then, the size of the first gap 41 is adjusted by the adjusting member. When the first gap 41 is adjusted, the first adjustment pad 31 is placed in the first gap 41, and then the limiting sleeve 71 is moved from the second position to the first position. Finally, the stopper 72 is tightened to lock the limiting sleeve 71 in the first position.

[0050] Furthermore, the base 10 includes a first base body 11, a second base body 12 and a support plate 13. The first base body 11 is connected to the second base body 12. The support plate 13 is connected to one end of the second base body 12 close to the first base body 11. The support plate 13 and the first base body 11 are arranged to form a first installation cavity 101. The support plate 13 and the second base body 12 are arranged to form a second installation cavity (not shown in the figure). The second installation cavity is used to install the input gear 61.

[0051] Specifically, after the bevel gear transmission mechanism is assembled, the transmission assembly 20 is fixed in the first installation cavity 101 to prevent other external components from affecting the transmission assembly 20. Figure 5 As shown, the support plate 13 is provided with a first avoidance opening 132, the first avoidance opening 132 is communicated with the first installation cavity 101, and the first avoidance opening 132 is used to avoid the input gear 61, so that the input gear 61 can be meshed and connected with the first bevel gear 22, and the first seat body 11 is provided with a second avoidance opening 111, the second avoidance opening 111 is communicated with the first installation cavity 101, and the second avoidance opening 111 is used to avoid the output gear 62, so that the output gear 62 can be meshed and connected with the second bevel gear 23. On the other hand, a washer 34 is provided at one end of the rotating shaft 21 close to the support plate 13, and the washer 34 is usually used only as a general washer, and the washer 34 can also be eliminated by increasing the step thickness of the rotating shaft 21.

[0052] Furthermore, there is a second gap 42 between the support plate 13 and the second seat body 12; the bevel gear transmission mechanism also includes a second adjustment pad 32, the second adjustment pad 32 includes multiple different specifications, and the thickness of each specification of the second adjustment pad 32 is different. Multiple different specifications of the second adjustment pad 32 can be selectively embedded in the second gap 42.

[0053] When the input gear 61 is meshed with the first bevel gear 22, a certain gap may appear between the input gear 61 and the first bevel gear 22. If the gap is too large, the power transmitted by the first bevel gear 22 may be weakened or the first bevel gear 22 may be disengaged from the input gear 61, eventually causing the bevel gear transmission mechanism to fail. If the gap is too small, the input gear 61 may interfere with the first bevel gear 22 during assembly. In order to solve the above problem, the present embodiment adjusts the gap between the first bevel gear 22 and the input gear 61 by adjusting the size of the second gap 42. Since one end of the transmission assembly 20 is fixed on the support plate 13, if the support plate 13 moves in a direction close to the second seat body 12, the gap between the first bevel gear 22 and the input gear 61 will be reduced accordingly. If the support plate 13 moves in a direction away from the second seat body 12, the gap between the first bevel gear 22 and the input gear 61 will increase. Specifically, when adjusting the gap between the first bevel gear 22 and the input gear 61, the first seat body 11 is first disassembled, and then the size of the second gap 42 is adjusted to reduce or increase the gap between the first bevel gear 22 and the input gear 61. After adjusting the gap between the first bevel gear 22 and the input gear 61, the size of the second gap 42 is measured, and according to the size of the second gap 42, a second adjustment pad 32 having the same thickness as the width of the second gap 42 is selected, and the second adjustment pad 32 is installed in the second gap 42, and finally the first seat body 11 is connected to the second seat body 12.

[0054] Furthermore, the support plate 13 and the second seat body 12 are connected by a second fixing member (not shown in the figure), and a second adjustment hole 131 is opened on the support plate 13, and the axial direction of the second adjustment hole 131 is consistent with the axial direction of the rotating shaft 21. The adjusting member is detachably penetrated through the second adjustment hole 131 and abuts against the second seat body 12, and the adjusting member cooperates with the second fixing member to adjust the size of the second gap 42.

[0055] Similar to adjusting the size of the first gap 41, the size of the second gap 42 in this embodiment is also adjusted by an adjusting member. Specifically, after the adjusting member passes through the second adjusting hole 131 and abuts against the second seat body 12, an external force is applied to the adjusting member to move the second seat body 12 away from the support plate 13, thereby increasing the size of the second gap 42. In addition, the second seat body 12 and the support plate 13 are connected by a second fixing member, and the second fixing member passes through the support plate 13 and the second seat body 12 in sequence. When it is necessary to reduce the second gap 42, the second fixing member between the second seat body 12 and the support plate 13 is locked so that the second seat body 12 moves in a direction close to the support plate 13, and finally the second gap 42 is reduced, and at this time the gap between the first bevel gear 22 and the input gear 61 is reduced.

[0056] As attached Figure 1 As shown, there is a third gap 43 between the first seat body 11 and the transmission assembly 20; the bevel gear transmission mechanism also includes a third adjustment pad 33, the third adjustment pad 33 includes multiple different models, and the thickness of each specification of the third adjustment pad 33 is different. Multiple different specifications of the third adjustment pad 33 can be selectively embedded in the third gap 43.

[0057] Specifically, after the transmission assembly 20 is installed in the first installation cavity 101, in order to prevent the third gap 43 between the transmission assembly 20 and the first seat body 11 from causing the transmission assembly 20 to shake in the first installation cavity 101, it is necessary to fill the third gap 43 with a third adjustment pad 33 so that the bevel gear transmission mechanism is fixed between the third adjustment pad 33 and the first seat body 11. Specifically, when assembling the third adjustment pad 33, first measure the size of the third gap 43. If the structure is convenient for direct measurement, then measure directly. If it is not convenient for direct measurement, then use the indirect measurement method. The indirect measurement method is: first install the third adjustment pad 33 of a larger specification so that a certain gap appears between the first seat body 11 and the second seat body 12, and measure the gap, which is the amount by which the thickness of the installed third adjustment pad 33 needs to be reduced, so as to determine the actual thickness specification of the third adjustment pad; then remove the first seat body 11, and according to the measured width of the third gap 43, select a third adjustment pad 33 with the same thickness as the width of the third gap 43 and sleeve it on the rotating shaft 21, and finally connect the first seat body 11 with the second seat body 12, so that the transmission assembly 20 is fixed in the first installation cavity 101. In this embodiment, when adjusting the third gap 43, it is also unnecessary to disassemble the first bevel gear 22 and the second bevel gear 23.

[0058] When adjusting the gear meshing clearance, the input gear 61 and the output gear 62 are actually adjusted accordingly at the same time, but this is not within the scope of this mechanism. At the same time, the adjustment order of the first clearance, the second clearance, and the third clearance should be determined according to the specific assembly structure of the input gear 61 and the output gear 62; usually, the assembly positions of the input gear 61 and the output gear 62 are relatively fixed to the second seat body 12 and the first seat body 11, respectively, so the adjustment of the second and third clearances will affect the first clearance. At this time, the first clearance should be adjusted last, that is, the adjustment order is: second clearance, third clearance, first clearance. However, no matter what the clearance adjustment order is, there is no need to disassemble the first bevel gear 22 and the second bevel gear 23 assembly.

[0059] Furthermore, a key 223 is provided on one of the first bevel gear 22 and the second bevel gear 23, and a key slot (not shown in the figure) matched with the key 223 is provided on the other of the two, and the key 223 is inserted in the key slot; the bevel gear transmission mechanism also includes a processor (not shown in the figure), a monitoring probe 91 and a monitoring shaft 92, the monitoring probe 91 is electrically connected to the processor, the monitoring probe 91 is penetrated through the base 10 and close to the transmission assembly 20, the monitoring shaft 92 is penetrated between the first bevel gear 22 and the second bevel gear 23 along the axial direction of the rotating shaft 21, the monitoring shaft 92 has a third position that moves to a position close to the monitoring probe 91 and causes the monitoring probe 91 to release an electrical signal and a fourth position away from the monitor, and the monitoring probe 91 and the monitoring shaft 92 are used to monitor the deformation of the key 223.

[0060] In a specific embodiment, a keyway is provided on the first bevel gear 22, and a key 223 is provided on the second bevel gear 23. The key 223 is inserted into the keyway. The power on the first bevel gear 22 and the second bevel gear 23 is transmitted through the key 223 and the keyway. When the torque on the first bevel gear 22 is too large, the key 223 on the second bevel gear 23 may be twisted and deformed, resulting in a reduction in the transmission efficiency of the transmission assembly 20 or even causing a damage accident. Therefore, in order to monitor whether the key 223 on the second bevel gear 23 is deformed, the bevel gear transmission mechanism in this embodiment is provided with a processor, a monitoring probe 91 and a monitoring shaft 92. The monitoring shaft 92 is used to monitor whether the key 223 is deformed. That is, when the key 223 is deformed, the monitoring shaft 92 moves from the fourth position to the third position in a direction close to the monitoring probe 91. At this time, the monitoring probe 91 releases an electrical signal. After receiving the electrical signal, the processor immediately stops the bevel gear transmission mechanism and issues an alarm. When the key 223 is not deformed, the monitoring shaft 92 is fixed at the fourth position and does not move. At this time, the monitoring probe 91 does not send an electrical signal.

[0061] Furthermore, a locking hole 224 is opened in the radial direction of the second bevel gear 23, and the bevel gear transmission mechanism includes a locking piece 95 and a limit pin 94. The locking piece 95 is arranged on the outer periphery of the second bevel gear 23, and the locking piece 95 is connected to the first end of the limit pin 94. The second end of the limit pin 94 is passed through the locking hole 224 and abuts against the monitoring shaft 92. The locking piece 95 is rotated by an external force so that the second end of the limit pin 94 moves in a direction close to or away from the monitoring shaft 92.

[0062] In this embodiment, the limit pin 94 abuts against the monitoring shaft 92 to fix the monitoring shaft 92 in the fourth position. When the key 223 is deformed too much, the limit pin 94 may be separated from the monitoring shaft 92, that is, the deformation of the key 223 causes the limit pin 94 to be deformed, and finally the monitoring shaft 92 moves from the fourth position to the third position. At this time, the monitoring probe 91 generates an induced electrical signal to monitor the deformation of the key 223. In addition, the locking member 95 is used to lock the limit pin 94 whose position has been adjusted. The locking member 95 and the limit pin 94 can be adjusted in position through threads to adjust the pressure applied by the limit pin 94 to the monitoring shaft 92, that is, the monitoring threshold can be adjusted. When the key 223 is deformed to a certain extent, the monitoring shaft 92 will move from the fourth position to the third position. In this embodiment, the locking member 95 can be an adjusting bolt.

[0063] In this embodiment, the first bevel gear 22 and the second bevel gear 23 are respectively provided with a first limiting hole 221 and a second limiting hole 231, the monitoring shaft 92 is respectively inserted into the first limiting hole 221 and the second limiting hole 231, and the locking hole 224 is connected with the second limiting hole 231; a limiting flange 921 is provided on the monitoring shaft 92, the limiting flange 921 and the first limiting hole 221 are clearance-matched, a first adjustment pad 31 is provided between the first limiting hole 221 and the second limiting hole 231, and the monitoring shaft 92 is sequentially inserted into the first limiting hole 221, the first adjustment pad 31 and the second limiting hole 231. In this embodiment, an elastic element 93 is also provided in the first limiting hole 221, and the elastic element 93 includes a spring, and the two ends of the spring are respectively pressed against the first adjustment pad 31 and the limiting flange 921. In other embodiments, a stop pad 35 is further provided in the first limiting hole 221 , the stop pad 35 is abutted against the first adjustment pad 31 , and both ends of the spring respectively abut against the stop pad 35 and the limiting flange 921 , thereby avoiding unstable contact between the spring and the first adjustment pad 31 .

[0064] As attached Figure 2 , Attachment Figure 6 And attached Figure 7 As shown, the second bevel gear 23 is provided with a plurality of locking holes 224 at intervals in the circumferential direction; the monitoring probes 91 and the monitoring shafts 92 each include a plurality, each monitoring probe 91 and each monitoring shaft 92 is provided in a one-to-one correspondence, and the bevel gear transmission mechanism includes a plurality of locking members 95 and a plurality of limit pins 94, each locking member 95 is connected to the first end of each limit pin 94 in a one-to-one correspondence; wherein, when the limit pin 94 is deformed by an external force, the second end of the limit pin 94 moves in a direction approaching or away from the monitoring shaft 92, wherein at least one limit pin 94 moves in a direction away from the monitoring shaft 92.

[0065] That is to say, during normal operation, one end of the limit pin 94 is clamped on the monitoring shaft 92, so that the monitoring shaft 92 is in the fourth position. When the load torque causes the second bevel gear 23 and the first bevel gear 22 to deform relative to each other, the limit pin 94 is subjected to external force, thereby generating relative displacement with the monitoring shaft 92. Since the plurality of limit pins 94 are arranged at intervals relative to the circumferential direction of the second bevel gear 23, some limit pins 94 move in a direction away from the monitoring shaft 92, and some limit pins 94 move in a direction close to the monitoring shaft 92. When there is a limit pin 94 moving in a direction away from the monitoring shaft 92, and the limit pin 94 is subjected to too much external force, it is difficult to apply a resisting force to the monitoring shaft 92, the limit pin 94 completely detaches from the monitoring shaft 92, and the monitoring shaft 92 moves to the third position under the action of the elastic element 93, thereby approaching the monitoring probe 91, triggering an induction electrical signal, and then confirming that the key 223 is excessively deformed, and the processor performs an early warning and shutdown process. The above devices constitute an automatic monitoring component. In a preferred embodiment, the locking holes 224 include at least two, and the at least two locking holes are symmetrically arranged along the same radial direction of the second bevel gear 23 .

[0066] In the present application, the adjustment of each gap in the bevel gear transmission mechanism includes the following embodiments:

[0067] Embodiment 1: Adjust the first gap 41, that is, adjust the gap between the second bevel gear 23 and the output gear 62. First, disassemble the second seat body 12 and the support plate 13, and then loosen the first fixing member 51 between the first bevel gear 22 and the second bevel gear 23. Then, pass the adjusting member through the first adjustment hole 222, and adjust the adjusting member and the first fixing member 51 at the same time so that the gap between the second bevel gear 23 and the output gear 62 reaches the predetermined gap. At this time, measure the width of the first gap 41, and select the first adjustment pad 31 with the same thickness as the width of the first gap 41 to be embedded in the first gap 41. Finally, disassemble the adjusting member, tighten the first fixing member 51, and then assemble the second seat body 12 and the support plate 13 in sequence.

[0068] Embodiment 2: Adjust the second gap 42, that is, adjust the gap between the first bevel gear 22 and the input gear 61. First, disassemble the first seat body 11 and loosen the second fixing piece. Then, pass the adjusting piece through the second adjustment hole 131 and press it against the second seat body 12. When external force is applied to the adjusting piece, the second seat body 12 moves in a direction away from the support plate 13. At the same time, according to the size of the second gap 42, tighten or loosen the second fixing piece so that the gap between the first bevel gear 22 and the input gear 61 reaches a predetermined value. Subsequently, select a second adjustment pad 32 whose thickness matches the width of the second gap 42 and pass it through the second gap 42. Finally, remove the adjusting piece, tighten the second fixing piece, and install the first seat body 11.

[0069] Embodiment 3: Adjust the third gap 43, that is, prevent the transmission assembly 20 from shaking in the first installation cavity 101. First, measure the size of the third gap 43. It should be noted that if the bevel gear transmission mechanism is convenient for directly measuring the size of the third gap 43, then measure it directly. If it is not convenient for direct measurement, then use an indirect measurement method. The indirect measurement method is: first install a third adjustment pad 33 of a larger specification in the third gap 43, so that a certain gap appears between the first seat body 11 and the second seat body 12, and measure the gap. The gap is the amount by which the thickness of the installed third adjustment pad 33 needs to be reduced, so as to determine the actual thickness specification of the third adjustment pad 33. Then remove the first seat body 11, and according to the size of the third gap 43, select a third adjustment pad 33 with the same thickness as the width of the third gap 43 and install it on the rotating shaft 21. Finally, connect the first seat body 11 with the second seat body 12.

[0070] According to Example 1, Example 2 and Example 3, it can be found that when adjusting the first gap 41, the second gap 42 and the third gap 43, the bevel gear transmission mechanism of the present application does not need to disassemble the first bevel gear 22 and the second bevel gear 23, thereby improving the efficiency of adjusting the first gap 41, the second gap 42 and the third gap 43 to a certain extent.

[0071] It is particularly noted that the adjustment sequence of the first gap 41, the second gap 42 and the third gap 43 should be determined according to the specific assembly structure of the input gear 61 and the output gear 62; usually, the assembly positions of the input gear 61 and the output gear 62 are relatively fixed to the second seat body 12 and the first seat body 11, respectively, so the adjustment of the second gap 42 and the third gap 43 will affect the first gap 41. At this time, the first gap 41 should be adjusted last, that is, the adjustment sequence is: second gap 42, third gap 43, first gap 41.

[0072] In summary, the first adjustment pad 31 in the present application is composed of a plurality of segmented arc segments 311, and the plurality of segmented arc segments 311 can be directly embedded in the first gap 41 or directly taken out from the first gap 41, thereby avoiding the need to disassemble the first bevel gear 22 and the second bevel gear 23 before operating the first adjustment pad 31, thereby improving the adjustment efficiency of the bevel gear transmission mechanism when adjusting the first gap 41. In addition, the first adjustment pad 31 in the present application also includes specifications of a plurality of different thicknesses. According to the adjustment of the first gap 41, a matching first adjustment pad 31 can be selected to be embedded in the first gap 41, thereby preventing the first adjustment pad 31 from being incompatible with the first gap 41 in size, resulting in a change in the relative position of the first bevel gear 22 and the second bevel gear 23 after rotation. On the other hand, the present application provides a first adjustment hole 222 on the first bevel gear 22, and the first adjustment hole 222 cooperates with the first fixing member 51 to quickly adjust the first gap 41 without disassembling the first bevel gear 22 and the second bevel gear 23. Similarly, in the present application, a second adjustment hole 131 is provided on the support plate 13, and an adjustment member is inserted into the second adjustment hole 131 and cooperates with the second fixing member to adjust the size of the second gap 42; and the second adjustment pad 32 includes a plurality of different thickness specifications. According to the adjusted size of the second gap 42, a second adjustment pad 32 with a thickness equal to the width of the second gap 42 can be selected to be installed in the second gap 42, thereby preventing the width of the second gap 42 from changing. In addition, in the present application, the third adjustment pad 33 also includes a plurality of different thickness specifications. The size of the third gap 43 is measured by direct measurement or indirect measurement method, and a third adjustment pad 33 with a thickness equal to the width of the third gap 43 can be selected to be installed in the third gap 43, thereby preventing the transmission assembly 20 from shaking in the first installation cavity 101. At the same time, according to the specific assembly structure of the input gear 61 and the output gear 62, the adjustment order of the first gap 41, the second gap 42, and the third gap 43 is determined; under normal circumstances, the assembly positions of the input gear 61 and the output gear 62 are relatively fixed to the second seat body 12 and the first seat body 11, respectively, and the adjustment order is: second gap 42, third gap 43, first gap 41. Finally, the present application sets a monitoring probe 91 and a monitoring shaft 92 on the bevel gear transmission mechanism. The monitoring probe 91 cooperates with the monitoring shaft 92 to monitor whether the key 223 on the second bevel gear 23 is deformed, thereby avoiding serious deformation of the key 223 on the second bevel gear 23, which causes the bevel gear transmission mechanism to be unable to be used normally.

[0073] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0074] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
