Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an adjustable speed reduction servo motor. Background Technology

[0002] A servo geared motor consists of a motor body and a reduction mechanism. The motor body provides power, while the reduction mechanism reduces the speed and increases the torque through a gear set. Its core function is to convert the high-speed, low-torque output of the motor into a low-speed, high-torque output, meeting the specific power parameter requirements of the equipment.

[0003] However, in existing technologies, the transmission ratio of gear sets is fixed, and it is impossible to provide different transmission ratios according to different loads of the motor, resulting in poor adaptability. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an adjustable geared servo motor to solve the problem in the prior art that the transmission ratio of the gear set is fixed and cannot provide different transmission ratios according to different loads of the motor, resulting in poor adaptability.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] An adjustable geared servo motor includes a motor body and a reduction mechanism. The reduction mechanism includes a housing, within which a first drive shaft and a second drive shaft are rotatably mounted. The output shaft of the motor body is driveably connected to the first drive shaft. One end of the second drive shaft is rotatably mounted on the housing, and the other end protrudes outside the housing. A first mounting sleeve is slidably disposed on the first drive shaft along its axial direction. A first gear and a second gear are fixedly disposed on the first mounting sleeve. A second mounting sleeve is slidably disposed on the second drive shaft along its axial direction. A third gear and a fourth gear are fixedly disposed on the second mounting sleeve. An adjustment component is disposed within the housing. Both the first and second mounting sleeves are driveably connected to the adjustment component. When the first and second mounting sleeves move to the point where the first gear meshes with the third gear, the second gear disengages from the fourth gear. When the first and second mounting sleeves move to the point where the second gear meshes with the fourth gear, the first gear disengages from the second gear.

[0007] By setting up the above structure and controlling the operation of the adjustment component, the first and second mounting sleeves are moved, which switches the meshing state of the first gear and the third gear and the meshing state of the second gear and the fourth gear, thereby changing the transmission ratio. This allows the geared servo motor to provide different transmission ratios according to different loads, improving adaptability.

[0008] Furthermore, the adjustment assembly includes an adjustment gear, a mounting rod, and a locking element. The mounting rod is rotatably mounted on the housing, and the adjustment gear is fixedly connected to the mounting rod. Both the first mounting sleeve and the second mounting sleeve are provided with annular tooth segments. The upper and lower ends of the adjustment gear respectively mesh with the annular tooth segments of the first mounting sleeve and the second mounting sleeve. The locking element is used to lock the position of the mounting rod.

[0009] By setting up the above structure, rotating the locking component drives the adjusting gear to rotate, which in turn moves the first and second mounting sleeves, thereby achieving the adjustment of different transmission ratios. Then, the position of the mounting rod can be locked by the locking component. The operation is simple, convenient and quick.

[0010] Furthermore, the locking component includes a locking rod, one end of which is rotatably connected to the housing, and the other end extends out of the housing. The locking rod is fixedly connected to the end of the mounting rod located outside the housing. The housing has a first locking hole and a second locking hole. The locking rod is slidably provided with a locking pin that matches the first locking hole and the second locking hole.

[0011] By setting the above structure, the position of the locking rod can be locked by inserting the locking pin into the first locking hole or the second locking hole.

[0012] Furthermore, mounting posts are fixedly provided inside the housing at positions corresponding to the first and second locking holes. The mounting posts have threaded holes, and the ends of the locking posts have threaded sections. When the threaded sections are threaded into the threaded holes, the locking rod is fixed relative to the housing.

[0013] By setting the above structure, the locking pin can be threaded into the threaded hole to prevent the locking pin from moving at will.

[0014] Furthermore, one end of the first drive shaft is fixedly connected to the output shaft of the motor body. The first drive shaft includes a first mounting section, and the first mounting sleeve is slidably mounted on the first mounting section. Both ends of the first mounting section are provided with first limiting heads.

[0015] By setting the above structure, a sliding connection between the first mounting sleeve and the first drive shaft is achieved.

[0016] Furthermore, the second drive shaft includes a second mounting section, and the second mounting sleeve is slidably mounted on the second mounting section. Both ends of the second mounting section are provided with second limiting heads. The housing is provided with a stepped hole, and the second limiting head at one end of the second drive shaft is located in the stepped hole. The stepped hole is used to prevent the second drive shaft from moving away from the motor body.

[0017] By setting the above structure, a sliding connection between the second mounting sleeve and the second drive shaft is achieved.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model, by setting a first mounting sleeve, a second mounting sleeve, and an adjustment component, controls the operation of the adjustment component to drive the first and second mounting sleeves to move, thereby switching the meshing state of the first gear and the third gear and the meshing state of the second gear and the fourth gear, thus changing the transmission ratio. This allows the geared servo motor to provide different transmission ratios according to different loads, improving adaptability.

[0020] 2. This utility model, by setting an adjusting wheel, a mounting rod and a locking component, allows the first and second mounting sleeves to move by rotating the locking component to drive the adjusting gear, thereby achieving the adjustment of different transmission ratios. The position of the mounting rod can then be locked by the locking component. The operation is simple, convenient and quick.

[0021] 3. By setting an installation post and a threaded section, the locking post can be threaded into the threaded hole, preventing the locking post from moving at will. Attached Figure Description

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] like Figures 1-4As shown, this utility model discloses an adjustable geared servo motor, including a motor body 1 and a reduction mechanism. The reduction mechanism includes a housing 2, within which a first transmission shaft 3 and a second transmission shaft 4 are rotatably mounted. The output shaft of the motor body 1 is connected to the first transmission shaft 3. One end of the second transmission shaft 4 is rotatably mounted on the housing 2, and the other end protrudes from the housing 2 as an output shaft. A first mounting sleeve 31 is slidably disposed on the first transmission shaft 3 along its axial direction. A first gear 32 and a second gear 33 are fixedly disposed on the first mounting sleeve 31. The second transmission shaft 4 is slidably disposed on the first transmission shaft 3 along its axial direction. A second mounting sleeve 41 is axially slidably mounted on the second drive shaft 4. A third gear 42 and a fourth gear 43 are fixedly mounted on the second mounting sleeve 41. An adjustment assembly is located inside the housing 2. Both the first mounting sleeve 31 and the second mounting sleeve 41 are connected to the adjustment assembly. When the first mounting sleeve 31 and the second mounting sleeve 41 move to the point where the first gear 32 meshes with the third gear 42, the second gear 33 disengages from the fourth gear 43. Conversely, when the first mounting sleeve 31 and the second mounting sleeve 41 move to the point where the second gear 33 meshes with the fourth gear 43, the first gear 32 disengages from the second gear 33. During control, the adjustment assembly is activated, causing the first mounting sleeve 31 and the second mounting sleeve 41 to move, switching the meshing state of the first gear 32 with the third gear 42 and the meshing state of the second gear 33 with the fourth gear 43. This changes the transmission ratio, allowing the geared servo motor to provide different transmission ratios according to different loads, improving adaptability. It should be noted that the transmission ratio between the first gear 32 and the third gear 42 is not equal to the transmission ratio between the second gear 33 and the fourth gear 43.

[0035] In this embodiment, the adjustment assembly includes an adjusting gear 51, a mounting rod 52, and a locking element 53. The mounting rod 52 is rotatably mounted on the housing 2, and the adjusting gear 51 is fixedly connected to the mounting rod 52. Both the first mounting sleeve 31 and the second mounting sleeve 41 are provided with annular tooth segments 311. The upper and lower ends of the adjusting gear 51 mesh with the annular tooth segments 311 of the first mounting sleeve 31 and the second mounting sleeve 41, respectively. The locking element 53 is used to lock the position of the mounting rod 52. In other embodiments, the adjustment assembly can also be configured as a micro-drive motor with a self-locking function. In this embodiment, by setting the adjusting gear 51, the mounting rod 52, and the locking element 53, rotating the locking element 53 drives the adjusting gear 51 to rotate, which in turn drives the first mounting sleeve 31 and the second mounting sleeve 41 to move, achieving adjustment of different transmission ratios. The locking element 53 then locks the position of the mounting rod 52. No additional drive is required, making the operation simple, convenient, and quick.

[0036] In this embodiment, the locking member 53 includes a locking rod 531. One end of the mounting rod 52 is rotatably connected inside the housing 2, and the other end extends outside the housing 2. The locking rod 531 is fixedly connected to the end of the mounting rod 52 located outside the housing 2. The housing 2 has a first locking hole 21 and a second locking hole 22. A locking pin 532, which is adapted to the first locking hole 21 and the second locking hole 22, is slidably disposed on the locking rod 531. In this embodiment, it is also possible to directly connect the locking pin 532 to the locking rod 531 without providing the first locking hole 21 and the second locking hole 22, and lock the locking rod 531 by the friction between the locking pin 532 and the outer wall of the housing 2. In this embodiment, by providing the first locking hole 21 and the second locking hole 22, the locking pin 532 can be inserted into the first locking hole 21 or the second locking hole 22 to achieve the position locking of the locking rod 531, and the locking state is more stable.

[0037] In this embodiment, mounting posts 23 are fixedly provided inside the housing 2 at positions corresponding to the first locking hole 21 and the second locking hole 22. Each mounting post 23 has a threaded hole, and the end of the locking post 532 has a threaded section. When the threaded section is threaded into the threaded hole, the locking rod 531 is fixed relative to the housing 2. The locking post 532 can be threaded into the threaded hole to prevent it from moving arbitrarily.

[0038] In this embodiment, one end of the first drive shaft 3 is fixedly connected to the output shaft of the motor body 1. The first drive shaft 3 includes a first mounting section 34, and a first mounting sleeve 31 is slidably fitted onto the first mounting section 34, realizing a sliding connection between the first mounting sleeve 31 and the first drive shaft 3. When the first drive shaft 3 rotates, it drives the first mounting sleeve 31 to rotate synchronously. In some other embodiments, the sliding connection between the first mounting sleeve 31 and the first drive shaft 31 can also be realized by means of slide rails and slide grooves. Both ends of the first mounting section 34 are provided with first limiting heads 35, which are used to limit the maximum range of movement of the first mounting sleeve 31.

[0039] The second drive shaft 4 includes a second mounting section 44, and a second mounting sleeve 41 is slidably fitted onto the second mounting section 44. When the second mounting sleeve 41 rotates, it drives the second drive shaft 4 to rotate synchronously, thus achieving a sliding connection between the second mounting sleeve 41 and the second drive shaft 4. In some other embodiments, the sliding connection between the second mounting sleeve 41 and the second mounting sleeve 44 can also be achieved by means of a slide rail and a slide groove. Both ends of the second mounting section 44 are provided with second limiting heads 45. A stepped hole is provided on the housing 2. The second limiting head 45 at one end of the second drive shaft 4 is located in the stepped hole. The stepped hole is used to prevent the second drive shaft 4 from moving away from the motor body 1, thus achieving a rotational connection between the second drive shaft 4 and the housing 2. It should be noted that the lengths of the two first limiting heads 35 on the first mounting section 34 in this embodiment can be set to different lengths depending on the installation position. The lengths of the two second limiting heads 45 on the second mounting section 44 can also be set to different lengths depending on the installation position.

[0040] The working principle of this utility model is as follows:

[0041] When it is necessary to adjust the meshing state of the first gear 32 and the third gear 42 to the meshing state of the second gear 33 and the fourth gear 43:

[0042] First, unscrew the locking pin 532 from the first locking hole 21;

[0043] Then, rotate the locking lever 531. The locking lever 531 drives the mounting lever 52 to rotate. The mounting lever 52 drives the adjusting gear 51 to rotate. The adjusting gear 51 rotates, causing the first mounting sleeve 31 and the second mounting sleeve 41 to move synchronously in opposite directions until the second gear 33 meshes with the fourth gear 43. At the same time, the first gear 32 disengages from the third gear 42.

[0044] Finally, screw the locking pin 532 into the threaded hole of the second locking hole 22 corresponding to the mounting pin 23.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
