Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a driving gear assembly structure. Background Art

[0002] With the progress of technology and the increasing diversification of industrial application requirements, in the field of mechanical transmission, traditional transmission methods such as the worm and worm gear mechanism and the planetary gear system each have their unique advantages, but there are still insurmountable limitations in terms of function. Among them, the worm and worm gear mechanism is widely used in occasions where reverse rotation needs to be prevented due to its high-efficiency self-locking characteristic, such as hoisting machinery, safety braking systems, etc. However, the non-coaxiality of its power transmission path limits the flexibility of its installation design, space utilization efficiency, and application in scenarios with high-efficiency requirements. At the same time, its speed change effect is poor. The planetary gear system, with its coaxial output, compact structure, high transmission efficiency, and good speed change effect, successfully solves the problem of transmission under a compact space layout and provides a high-efficiency transmission ratio. It occupies an important position in fields such as aerospace, automotive transmission, and industrial automation. However, the traditional planetary gear system lacks a self-locking function, resulting in serious defects in some mechanical applications that require ensuring position locking or preventing accidental rotation, and its speed change effect is also relatively limited, with a narrow applicable range and poor versatility. Summary of the Utility Model

[0007] At least part of the outer teeth are formed on the driving gear, a first inner tooth is formed on the driven gear disk, and the outer teeth are engaged with the first inner teeth to drive the driven gear disk to rotate.

[0008] According to the above technical means, the driving plate cooperates with the first shaft hole through the eccentric shaft to drive the eccentric swinging motion of the driving gear, so that under the action of the outer teeth and the first internal teeth on the driven gear plate, the driven gear plate is driven to rotate, thereby achieving the effect of the driving gear swinging to drive the driven gear plate to rotate coaxially, overcoming the limitations of traditional mechanical transmission methods in space utilization and transmission flexibility. The transmission structure is simple, compact, flexible and reliable, and has a wide range of applications.

[0010] According to the above technical means, by matching the first guide structure on the floating block with the second guide structure on the driving gear, the motion trajectory of the driving gear is restricted by the floating block, thereby forming a reduction gear ratio when transmitting the driven gear disc. At the same time, the driven gear disc cannot drive the driving gear to reverse, and has a self-locking function, high flexibility, and a wide range of applications. It realizes both coaxial output and integrated self-locking function, and the precise sliding guide of the driving gear on the floating block not only enhances the stability and reliability of the gear transmission, but also effectively reduces the wear and noise caused by motion deviation, thereby improving the overall mechanical transmission efficiency and life.

When the first guide structure is a slide groove and the second guide structure is a slider, the manufacturing process is simple, and the strength of the overall structure of the driving gear is ensured.

[0014] According to the above technical means, the housing is used to install and protect the drive disk, floating block, driving gear and driven gear disk to prevent them from being interfered by the outside world. Through the matching of the third guiding structure on the floating block and the fourth guiding structure on the housing, when the driving gear moves, the floating block can perform a limiting activity inside the housing, thereby realizing double guiding for the driving gear, making the movement track of the driving gear more flexible, further improving the stability and precision of the overall transmission, ensuring that the sliding of the floating block inside the housing is both stable and precise, effectively avoiding additional wear and noise caused by shaking or offset, while enhancing the overall rigidity and durability, enabling this structure to maintain excellent performance in more severe or high - requirement working environments, and also improving the reliability and service life of the equipment.

[0015] Further, the third guiding structure is a chute, and the fourth guiding structure is a guiding block.

[0016] According to the above technical means, through the cooperation of the chute and the guiding block, the stability and accuracy of the sliding of the floating block inside the housing during the movement of the driving gear are ensured, thereby guaranteeing the smoothness and precision of the driving gear transmission.

[0017] Further, the floating block is located between the drive disk and the driving gear.

[0018] According to the above technical means, the floating block is located between the drive disk and the driving gear, enabling the driving gear to achieve precise swinging under the drive of the eccentric shaft of the drive disk through the limiting effect of the floating block. At the same time, as an intermediate medium, the floating block effectively buffers the direct impact and vibration between the drive disk and the driving gear, reducing energy loss and mechanical wear during the transmission process.

[0019] Further, the driven gear disk is provided with a mounting shaft, and a second shaft hole is formed on the eccentric shaft, and the mounting shaft is inserted into the second shaft hole.

[0020] According to the above technical means, the driven gear disk is coaxially connected to the drive disk by inserting the mounting shaft into the second shaft hole on the eccentric shaft, simplifying the transmission path, improving the transmission efficiency, ensuring the stable rotation of the driven gear disk under the drive of the eccentric shaft, enhancing the reliability of the transmission, making the driven gear disk more stable when bearing loads, and reducing the offset and wear caused by external vibration or impact.

[0021] Further, a driving gear is provided on the driven gear disc, and the driving gear is located on a side of the driven gear disc away from the driving gear.

[0022] According to the above technical means, the driving gear is used to transmit the power on the driven gear disc to other components, realizing the effective transmission and conversion of power. Moreover, the driving gear is located on one side of the driven gear disc, avoiding direct interference with the driving gear, reducing friction and loss during transmission, ensuring the transmission efficiency, having a compact structure, and improving the space utilization rate.

[0023] Further, a power gear assembly is further included. A second internal tooth is formed on the driving disc, and the power gear assembly meshes with the second internal tooth to drive the driving disc to rotate.

[0024] According to the above technical means, by the transmission and meshing of the power gear assembly and the second internal tooth, the driving disc can be directly and efficiently driven to rotate, thereby driving the swing of the eccentric shaft and the driving gear, realizing the smooth conversion and efficient transmission of power input. It not only improves the transmission efficiency but also makes the overall power output more stable and reliable.

[0025] Further, the power gear assembly includes a first planetary gear set and a second planetary gear set. The first planetary gear set is configured to be able to drive the driving disc to rotate, and the second planetary gear set is configured to be able to drive the first planetary gear set to rotate.

[0026] According to the above technical means, by the second planetary gear driving the first planetary gear set to rotate, and the first planetary gear set driving the driving disc to rotate, not only the multi-stage transmission of power is realized, but also through the special structure of the planetary gear set, the rotation speed of the driving disc is further reduced, making the transmission process smoother, with lower noise, and having higher transmission efficiency.

[0027] Further, the first planetary gear set includes a first master gear and more than two first sub-gears.

[0029] According to the above technical means, in the first planetary gear set, the meshing of the first mother gear and multiple first sub-gears realizes the uniform distribution and transmission of power, ensuring the smoothness and reliability of the transmission. At the same time, the first sub-gear meshes directly with the second internal teeth on the driving disc, further enhancing the rotational stability of the driving disc and torque output; in the second planetary gear set, the second mother gear drives multiple second sub-gears to rotate, and the second sub-gears then mesh with the third internal teeth on the planetary gear disc, finally driving the driving disc to rotate, realizing the multi-stage amplification and efficient transmission of power. Through the multi-stage transmission and meshing mechanism, the overall stability and torque output ability are enhanced.

[0042] The technical solutions of the present utility model will be described in detail below with reference to specific drawings.

[0043] This embodiment relates to a drive gear assembly structure, as Figure 1 and Figure 3 shown, including a drive disk 1, a driving gear 2, and a driven gear disk 3; an eccentric shaft 11 is provided on the drive disk 1, a first shaft hole 21 is formed on the driving gear 2, and the eccentric shaft 11 is inserted into the first shaft hole 21 to drive the driving gear 2 to swing; at least a part of the outer teeth 22 are formed on the driving gear 2, a first inner tooth 31 is formed on the driven gear disk 3, and the outer teeth 22 are engaged with the first inner teeth 31 to drive the driven gear disk 3 to rotate.

[0044] In this embodiment, through the sequential transmission of the drive disk 1, the driving gear 2, and the driven gear disk 3, high-efficiency coaxial transmission is achieved. During specific operation, the eccentric shaft 11 on the drive disk 1 is inserted into the first shaft hole 21 of the driving gear 2. When the drive disk 1 rotates, the eccentric movement of the eccentric shaft 11 is converted into the swing of the driving gear 2, causing the outer teeth 22 on the driving gear 2 to reciprocate back and forth, so as to continuously engage with the first inner teeth 31 on the driven gear disk 3, thereby driving the driven gear disk 3 to rotate to achieve effective power transmission. It has a good speed reduction and speed change effect, overcomes the limitations of traditional mechanical transmission methods in terms of space utilization and transmission flexibility, has a simple transmission structure, is compact, has a wide application range, ensures the high efficiency and stability of power transmission, meets the high requirements for transmission efficiency and speed change effect, can better adapt to the needs of a compact space, improves the overall transmission efficiency and working performance, overcomes the limitation of its non-coaxiality, lays a more flexible and efficient foundation for diverse mechanical transmission applications, and drives the driven gear disk 3 to perform complex and flexible rotation through the swing movement, improving the adaptability and flexibility of the transmission, enabling stable power output under various working conditions, while reducing the impact and wear in traditional rigid transmission and extending the service life of each component.

[0045] In this embodiment, it further includes a floating block 4. A first guiding structure 41 is formed on the floating block 4, and a second guiding structure 23 is formed on the driving gear 2. The first guiding structure 41 is adapted to the second guiding structure 23 to guide the driving gear 2 to slide on the floating block 4.

[0046] As Figure 1 and Figure 3 shown, as a preferred embodiment, the floating block 4 is located between the driving disc 1 and the driving gear 2. By matching the first guiding structure 41 on the floating block 4 with the second guiding structure 23 on the driving gear 2, the floating block 4 limits the movement track of the driving gear 2, so that when driving the driven gear disc 3, a reduction gear ratio is formed while the driven gear disc 3 cannot drive the driving gear 2 to reverse, realizing both coaxial output and integrated self-locking function. Specifically, as a preferred embodiment, when the first guiding structure 41 is a chute and the second guiding structure 23 is a slider, its specific working principle is as follows: the rotation of the driving disc 1 drives the movement of the driving gear 2 through the eccentric movement of the eccentric shaft 11. Thus, under the precise guiding action of the chute, the driving gear 2 slides in the chute through the slider, so that the driving gear 2 drives the driven gear disc 3 to rotate through the external teeth 22 while restricting the movement track, to form a deceleration effect. At the same time, the driving gear 2 cannot reverse and has a self-locking function, which not only enhances the stability and reliability of the gear transmission, but also effectively reduces the wear and noise caused by movement deviation, and improves the overall mechanical transmission efficiency and service life.

[0047] In this embodiment, it further includes a housing 6. A third guiding structure 42 is further formed on the floating block 4, and a fourth guiding structure 61 is formed on the housing 6. The third guiding structure 42 is adapted to the fourth guiding structure 61 to guide the floating block 4 to slide in the housing 6.

[0048] The housing 6 of this embodiment is used to install and protect components such as the driving disc 1, the floating block 4, the driving gear 2, and the driven gear disc 3 to prevent them from being interfered by the outside world, ensure the transmission effect, and extend the service life. As Figure 1 and Figure 4As shown, specifically, the third guiding structure 42 on the floating block 4 matches the fourth guiding structure 61 on the housing 6, enabling the floating block 4 to be limited in movement within the housing 6 when the driving gear 2 moves, thus achieving double guiding for the driving gear 2 and further enhancing the stability and precision of the overall transmission. As a preferred embodiment, when the third guiding structure 42 is a sliding groove and the fourth guiding structure 61 is a guiding block, the specific working principle is as follows: The rotation of the driving disk 1 drives the movement of the driving gear 2 through the eccentric movement of the eccentric shaft 11. Thus, under the precise guiding action of the two sliding grooves, the driving gear 2 slides in the two sliding grooves respectively through the slider and the guiding block, achieving double guiding for the driving gear 2. Finally, the driven gear disk 3 is driven to rotate through the external teeth 22. The movement trajectory of the driving gear 2 is more flexible, further enhancing the stability and precision of the overall transmission, ensuring that the sliding of the floating block 4 in the housing 6 is both stable and precise, effectively avoiding additional wear and noise caused by shaking or deviation, while enhancing the overall rigidity and durability, enabling this structure to maintain excellent performance in more severe or demanding working environments, and also improving the reliability and service life of the equipment.

[0049] In this embodiment, an installation shaft 32 is provided on the driven gear disk 3, and a second shaft hole 12 is formed on the eccentric shaft 11. The installation shaft 32 is inserted into the second shaft hole 12; as Figure 1 、 Figure 3 and Figure 4 shown, during installation, the driven gear disk 3 is coaxially connected to the driving disk through the insertion of the installation shaft 32 into the second shaft hole 12 on the eccentric shaft 11. The structure is compact, ensuring the stability of the driven gear disk 3 during transmission, ensuring the stable rotation of the driven gear disk 3 driven by the eccentric shaft 11, enhancing the reliability of the transmission, making the driven gear disk 3 more stable when bearing loads, and reducing offsets and wear caused by external vibration or impact.

[0050] In this embodiment, a driving gear 33 is provided on the driven gear disk 3, and the driving gear 33 is located on the side of the driven gear disk 3 away from the driving gear 2; as Figure 1 and Figure 2 shown, the driving gear 33 is used to transfer the power on the driven gear disk 3 to other components, achieving effective transmission and conversion of power. Moreover, the driving gear 33 is located on one side of the driven gear disk 3, avoiding direct interference with the driving gear 2, reducing friction and loss during transmission, ensuring the transmission efficiency, with a compact structure and improved space utilization rate.

[0051] In this embodiment, a power gear assembly 5 is further included. A second internal tooth 13 is formed on the driving disk 1, and the power gear assembly 5 meshes with the second internal tooth 13 to drive the driving disk 1 to rotate; as Figure 4As shown, during use, the power gear assembly 5 can be connected to an external power source (such as a motor). The power gear assembly 5 is driven by the motor, and the power gear assembly 5 meshes with the second internal gear 13 to drive the drive disk 1 to rotate, thereby driving the swing of the eccentric 11 to drive the driving gear 2, and finally driving the driven gear disk 3 to rotate, achieving smooth conversion and efficient transmission of power input. This not only improves the transmission efficiency but also makes the overall power output more stable and reliable.

[0052] Furthermore, as a preferred embodiment of the present invention, the power gear assembly 5 includes a first planetary gear set 51 and a second planetary gear set 52. The first planetary gear set 51 is configured to be able to drive the drive disk 1 to rotate, and the second planetary gear set 52 is configured to be able to drive the first planetary gear set 51 to rotate.

[0053] As Figure 2 and Figure 4 shown, through the first planetary gear set 51 and the second planetary gear set 52, not only is multi-stage power transmission achieved, but also through the special structure of the planetary gear set, the rotation speed of the drive disk is further reduced, making the transmission process smoother, with lower noise, and having higher transmission efficiency. Furthermore, as a preferred embodiment, the first planetary gear set 51 includes a first master gear 511 and more than two first sub-gears 512. The first master gear 511 meshes with each first sub-gear 512 to drive each first sub-gear 512 to rotate, and each first sub-gear 512 meshes with the second internal gear 13 to drive the drive disk 1 to rotate; the second planetary gear set 52 includes a planetary gear disk 521, a second master gear 522, and more than two second sub-gears 523. The second master gear 522 meshes with each second sub-gear 523 to drive each second sub-gear 523 to rotate; a third internal gear 524 is formed on the planetary gear disk 521, and each second sub-gear 523 meshes with the third internal gear 524; the first master gear 511 is fixed on the star gear disk 521;

[0054] During specific operation, preferably, the number of both the first sub-gears 512 and the second sub-gears 523 is three. The second master gear 522 is driven by the motor to drive each second sub-gear 523, thereby driving the planetary gear disk 521 to rotate through the engaged third internal gear 524 to complete the first-stage transmission of the second planetary gear set 52. Then, the planetary gear disk 521 drives each first sub-gear 512 to rotate through the first master gear 511, thereby driving the drive disk 1 to rotate through the second internal gear 13 to complete the second-stage transmission of the first planetary gear set 51. Finally, the floating block 4 and the driving gear 2 cooperate to drive the driven gear disk 3 to rotate, achieving efficient and controllable power transmission.
