Description

Technical Field

[0001] The utility model belongs to the field of gear transmission structures, and in particular relates to a motor gear transmission device and a motor gear adjustment structure thereof. Background Art

[0002] In the mechanical field, adjusting the backlash of a motor gear is an important step to ensure the stable and efficient operation of a mechanical transmission system. In some high-precision applications, it is necessary to avoid backlash, but there are also some applications that hope to retain backlash as a space for lubrication and to allow for thermal expansion and contraction. Generally, if the backlash is too large, it will affect the positioning accuracy and control accuracy of mechanical equipment, and also affect the smoothness of equipment operation. If the backlash is too small, it may cause the gears to be too tight, easily resulting in gear jamming, friction and wear, affecting equipment operation and generating noise and vibration. In order to improve transmission accuracy, reduce noise and vibration, extend the service life of equipment, and adapt to thermal expansion and load changes, it is a very important step to adjust the backlash of the motor gear.

[0003] Generally, gaskets of different thicknesses are used to adjust the position of the motor or gear, and the backlash is finely adjusted by replacing gaskets of different thicknesses, but it requires manual operation, disassembly, and adjustment, consuming a lot of labor and time costs. Therefore, in view of the problems of the above-mentioned prior art, the utility model further provides a motor gear transmission device and a motor gear adjustment structure thereof to solve the problems that have occurred. Summary of the Utility Model

[0004] In consideration of the above problems, the main purpose of the utility model is to provide a motor gear transmission device and a motor gear adjustment structure thereof that can precisely adjust the backlash, have a simple structure, and can be quickly operated and adjusted.

[0005] To achieve the above object, the utility model provides a motor gear adjustment structure, including a gear plate, a first inclined block, and a second inclined block. One side of the gear plate is connected to a gear linkage mechanism, and the gear linkage mechanism is connected to a motor gear. The first inclined block is arranged at the bottom of the gear plate. The first inclined block has an adjacent first connection surface, a first inclined surface, and a first abutting surface. The first connection surface is connected to the bottom of the gear plate. One end of the first inclined surface is connected to the first abutting surface, and the other end is connected to the first connection surface. The first abutting surface abuts against the side wall of the gear linkage mechanism. The second inclined block is arranged below the first inclined block. The surface of the second inclined block is a second inclined surface, and the second inclined surface contacts the first inclined surface. When the second inclined block is in a horizontal displacement state, the contact area between the first inclined surface and the second inclined surface changes, driving the gear plate to move up and down, and further driving the gear linkage mechanism.

[0006] In an embodiment of the present utility model, the motor gear adjustment structure further includes a locking member. The locking member is inserted into the locking hole of the second inclined block. The locking hole is located below the second inclined surface. The locking hole is connected to the side wall of the gear linkage mechanism through a locking member. By the pushing of the locking member, the second inclined block generates a horizontal displacement, changing the contact area between the first inclined surface and the second inclined surface, and further driving the gear plate in a linked manner.

[0007] In an embodiment of the present utility model, an annular groove is formed on one side of the gear plate connected to the gear linkage mechanism. The annular groove is connected to the gear linkage mechanism. In the state where the gear plate moves in height, the annular groove synchronously drives the gear linkage mechanism in a linked manner.

[0008] In an embodiment of the present utility model, the included angle between the first inclined surface and the first connecting surface is between 1 degree and 45 degrees.

[0009] Based on the above object, the present utility model further provides a motor gear transmission device, including a motor gear, a gear linkage mechanism, and the above-mentioned motor gear adjustment structure. The gear linkage mechanism is connected to the motor gear. The above-mentioned motor gear adjustment structure is connected to the gear linkage mechanism for adjusting the backlash and height of the motor gear.

[0010] Therefore, the motor gear transmission device and its motor gear adjustment structure of the present utility model have the following effects:

[0011] (1) Precise adjustment: By controlling the horizontal displacement of the second inclined block, precise adjustment of the backlash of the motor gear can be achieved through the linked movement of the gear plate.

[0012] (2) Reduced structural complexity: The adjustment mechanism is simple and does not require complex mechanical structures.

[0013] (3) Quick adjustment: The adjustment is convenient and fast, suitable for applications that require frequent fine-tuning.

[0014] (4) Wide application: It is applicable to various mechanical transmission systems that require precise backlash adjustment, such as robotic arms, precision instruments, and automation equipment.

[0048] Embodiments of the present utility model will be further described below in conjunction with relevant drawings. As much as possible, in the drawings and the specification, the same reference numerals represent the same or similar components. In the drawings, for the sake of simplicity and convenience of labeling, the shapes and thicknesses may be exaggerated. It can be understood that the components not specifically shown in the drawings or described in the specification are well known to those skilled in the art. Those skilled in the art can make various changes and modifications according to the content of the present utility model.

[0049] Please refer to Figures 1 to 3 , the motor gear adjustment structure 10 includes a gear plate 12, a first inclined block 14 and a second inclined block 16. One side of the gear plate 12 is connected to an external gear linkage mechanism 20. The first inclined block 14 is disposed at the bottom of the gear plate 12. The first inclined block 14 has an adjacent first connection surface 14B, a first abutting surface 14A and a first inclined surface 14C. The first connection surface 14B is connected to the bottom of the gear plate 12. The first abutting surface 14A abuts against the side wall of the gear linkage mechanism 20. One end of the first inclined surface 14C is connected to the first abutting surface 14A, and the other end is connected to the first connection surface 14B. The second inclined block 16 is disposed below the first inclined block 14. The surface of the second inclined block 16 is a second inclined surface 16C, and the second inclined surface 16C contacts the first inclined surface 14C. When the second inclined block 16 is in a horizontal displacement state, the contact area between the first inclined surface 14C and the second inclined surface 16C changes, driving the gear plate 12 to move up and down, and further driving the gear linkage mechanism 20.

[0050] Since, in the gear transmission structure, in order to adjust the backlash, the motor gear needs to be slightly adjusted. The gear plate 12, the first inclined block 14 and the second inclined block 16 of the present utility model can be mutually cooperated, and the gear plate 12 is driven to displace in the vertical direction by means of the inclined block pushing, so as to drive the gear linkage mechanism 20, and the backlash of the motor gear can be accurately fine-tuned.

[0051] Please refer to Figure 3, the motor gear adjustment structure 10 may further include a locking member 17. The locking member 17 is inserted into a locking hole 16A of the second inclined block 16. The locking hole 16A is located below the second inclined surface 16C. The locking hole 16A is connected to the side wall 20A of the gear linkage mechanism 20 through the locking member 17. By pushing the locking member 17, the second inclined block 16 generates a horizontal displacement, changing the contact area between the first inclined surface 14C and the second inclined surface 16C, and then driving the gear plate 12 to move accordingly.

[0052] Please refer to Figure 3 and Figure 4 , on one side of the gear plate 12 connected to the gear linkage mechanism 20, an annular groove 12A is formed. The annular groove 12A is connected to the gear linkage mechanism 20. When the gear plate 12 moves in height, the annular groove 12A synchronously drives the gear linkage mechanism 20. In some other embodiments, the annular groove 12A is not a perfect circle or ellipse, but a shape similar to a gourd with a smooth waist. During implementation, the shape of the annular groove 12A can be adjusted according to requirements, and it is not limited to this.

[0053] In some other embodiments, the dimensions among the gear plate 12, the first inclined block 14, and the second inclined block 16 may also conform to the following characteristics:

[0054] (1) The height h1 of the gear plate 12 is greater than the width w1 of the gear plate 12.

[0055] (2) The width w2 of the first connecting surface 14B of the first inclined block 14 is less than the thickness d1 of the gear plate 12.

[0056] (3) The thickness d2 of the second inclined block 16 is less than the thickness d1 of the gear plate 12.

[0057] Please refer to Figure 5 and Figure 6 , the included angle θ between the first inclined surface 14C and the first connecting surface 14B is between 1 degree and 45 degrees, and the preferred included angle θ is about 15 degrees.

[0058] In some other embodiments, the first inclined block 14 has a wedge-shaped structure, and the end faces 162 and 164 on the adjacent two sides of the second inclined surface 16C are parallel to each other.

[0059] Please refer to Figure 7 , when implementing the motor gear adjustment structure, if it is desired to displace the gear plate 12 downward, the locking member 17 inserted into the locking hole 16A is loosened. The locking member 17 moves the second inclined block 16 away from the first inclined block 14. Then, when the second inclined block 16 is in a horizontal displacement state, the contact area between the first inclined surface 14C and the second inclined surface 16C will decrease. Due to the slope fit, the first inclined block 14 will drive the gear plate 12 to move downward. Therefore, when the gear plate 12 is in a downward displacement state, the gear linkage mechanism 20 is driven to finely adjust the height, and then the motor gear can be controlled for adjustment.

[0060] Please refer to Figure 8 Figure 8 , when implementing the motor gear adjustment structure, if it is desired to displace the gear plate 12 upward, the locking member 17 is tightened to bring the second inclined block 16 closer to the first inclined block 14. Then, in the state where the second inclined block 16 is horizontally displaced, the contact area between the first inclined surface 14C and the second inclined surface 16C will increase, and the first inclined block 14 will push the gear plate 12 due to the slope fit, causing the gear plate 12 to be abutted and displaced upward. Therefore, in the state where the gear plate 12 is displaced upward, the gear linkage mechanism 20 will also be driven to finely adjust the height, and thus the adjustment of the motor gear can be controlled.

[0061] Please refer to Figure 9 and Figure 10 Figure 10 , the motor gear transmission device 1 includes a motor gear 30, a gear linkage mechanism 20, and the above-mentioned motor gear adjustment structure 10. The gear linkage mechanism 20 is connected to the motor gear 30. The above-mentioned motor gear adjustment structure 10 is connected to the gear linkage mechanism 20 for adjusting the backlash and height of the motor gear 30. Since the motor gear adjustment structure 10 has been specifically described above, it will not be elaborated here.

[0062] In summary, the motor gear transmission device of the present invention and its motor gear adjustment structure can achieve precise adjustment of the backlash and can be quickly operated and adjusted without a complex mechanical structure, and can be applied to various mechanical transmission systems that require precise backlash adjustment, such as robotic arms, precision instruments, and automation equipment.

[0063] The above is only an example to illustrate the preferred embodiments of the present invention, and is not intended to limit the scope of implementation. Any simple substitution and equivalent change made according to the claims and the content of the patent specification of the present invention shall fall within the scope of the patent application of the present invention.
