Description

Technical Field

[0001] This application relates to the field of mechanical transmission technology, and in particular to a transmission device and equipment. Background Technology

[0002] In the field of mechanical transmission, crank-slider mechanisms are often used to convert rotary motion into linear motion, but they are inefficient when subjected to large loads. Gear reduction mechanisms are often used in transmission systems that require speed reduction and torque increase, but they have limitations in motion conversion.

[0003] In related technologies, the two types of mechanisms are often deployed separately in practical applications, resulting in shortcomings in the transmission system in terms of load adaptability, motion compatibility and integration, making it difficult to meet the demand for efficient, compact and multifunctional transmission under complex working conditions. Utility Model Content

[0004] This application proposes a transmission device to effectively solve the technical problem in related technologies that makes it difficult to meet the requirements of efficient, compact, and multifunctional transmission under complex working conditions.

[0005] This application also proposes a device including the above-described transmission device.

[0006] The first aspect of this application provides a transmission device, including: a gear reduction mechanism and a crank-slider mechanism;

[0007] The gear reduction mechanism is used to reduce speed and increase torque, and the gear reduction mechanism includes an output shaft for outputting driving force;

[0008] The crank-slider mechanism includes a rocker arm component, a sliding component, and a first guide component. The sliding component is slidably connected to the first guide component. One end of the rocker arm component is connected to the output shaft, and the other end of the rocker arm component is movably connected to the sliding component, so that the output shaft can drive the sliding component to move under the guidance of the first guide component through the rocker arm component.

[0009] Furthermore, the sliding component is provided with a second guide component, and the other end of the swing arm component is provided with a hinge portion. The other end of the swing arm component is slidably connected to the sliding component via the hinge portion on the second guide component.

[0010] Furthermore, the guiding direction of the first guide component is perpendicular to the guiding direction of the second guide component.

[0011] Furthermore, the hinge portion is a deep groove ball bearing.

[0012] Furthermore, a groove is formed on the first guide component, and a sliding end is provided on the sliding component. The sliding component is slidably connected to the first guide component by being slidably disposed on the groove through the sliding end.

[0013] Furthermore, a friction bearing is provided between the sliding end and the sliding groove.

[0014] Furthermore, the gear reduction mechanism includes a driving gear and a driven gear. The driving gear is used to connect to the input shaft, and the driven gear is used to coaxially fix the output shaft. The output shaft is rigidly connected to the swing arm component. The driving gear and the driven gear mesh and drive each other, so that the output shaft can drive the swing arm component to swing synchronously by rotating.

[0015] Furthermore, both the driving gear and the driven gear are spur gears.

[0016] Furthermore, the number of teeth on the driving gear is less than the number of teeth on the driven gear.

[0017] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: by directly driving the swing arm component to swing through the output shaft, the crank-slider mechanism and the gear reduction mechanism are combined to form a new structural system, which not only retains the speed reduction and force amplification advantages of the gear reduction mechanism, but also achieves effective conversion of motion form with the help of the crank-slider mechanism, making up for the shortcomings when each is used alone, thereby improving the overall performance of the transmission system in terms of load adaptability and motion conversion capability.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] See Figures 1 to 3 As shown, an embodiment of the first aspect of this application discloses a transmission device, including a gear reduction mechanism 100 and a crank-slider mechanism 200;

[0031] The gear reduction mechanism 100 is used for speed reduction and torque increase. The gear reduction mechanism 100 includes an output shaft 110 for outputting driving force. The crank-slider mechanism 200 includes a rocker arm component 210, a sliding component 220 and a first guide component 230. The sliding component 220 is slidably connected to the first guide component 230. One end of the rocker arm component 210 is connected to the output shaft 110, and the other end of the rocker arm component 210 is movably connected to the sliding component 220, so that the output shaft 110 can drive the sliding component 220 to move under the guidance of the first guide component 230 through the rocker arm component 210.

[0032] In the embodiments of this application, the crank-slider mechanism 200 and the gear reduction mechanism 100 are combined to form a new structural system by directly driving the swing arm component 210 to swing through the output shaft 110. This retains the speed reduction and force amplification advantages of the gear reduction mechanism 100, while also using the crank-slider mechanism 200 to achieve effective conversion of motion mode, making up for the shortcomings of each when used alone, and thus improving the overall performance of the transmission system in terms of load adaptability and motion conversion capability.

[0033] Understandably, in some embodiments, the crank-slider mechanism 200 drives the connecting rod to swing through the rotational motion of the crank, thereby causing the slider to perform reciprocating linear motion, realizing the conversion of rotational motion to linear motion. This is widely used in linear transmission scenarios of equipment such as stamping presses and internal combustion engines. However, it lacks speed reduction and torque amplification, resulting in low efficiency and insufficient torque under high loads, and is prone to jamming or component failure. The gear reduction mechanism 100, through the meshing transmission of the driving and driven gears 130 (the driving gear 120 has fewer teeth than the driven gear 130), converts the high-speed rotational motion of the power source into the low-speed rotational motion of the driven gear 130. Based on the inverse relationship between torque and speed in gear transmission, it achieves force amplification and is often used in transmission systems requiring speed reduction and torque amplification, such as motor gearboxes and engineering machinery transmission devices. However, it cannot achieve the conversion between rotational and linear motion; an additional conversion mechanism is required when using linear actuators, increasing volume complexity and reducing accuracy.

[0034] If the crank-slider mechanism 200 and the gear reduction mechanism 100 can be combined to form a new structural system, it is expected to make up for the shortcomings of each when used alone. This way, the speed reduction and force amplification advantages of the gear reduction mechanism 100 can be retained, and the effective conversion of motion mode can be achieved with the help of the crank-slider mechanism 200, thereby improving the overall performance of the transmission system in terms of load adaptability and motion conversion capability.

[0035] Based on this, the first aspect of this application discloses a transmission device that integrates the two to achieve the conversion between rotary and linear motion while having the function of deceleration and torque amplification, thereby improving efficiency and torque under high load, reducing the need for external conversion mechanisms to reduce size, complexity, and accuracy, and meeting the requirements of complex working conditions.

[0036] It should be understood that the transmission device of this application has a tightly integrated structure. The power input to the transmission device is reduced by the gear reduction mechanism 100 and then output through the output shaft 110. The output shaft 110 is coaxial with the rocker arm component 210 of the crank-slider mechanism 200, so that the output shaft 110 of the driven gear 130 directly serves as the input shaft of the rocker arm component 210 without the need for additional connecting parts, resulting in a compact structure. In addition, the power transmission of the transmission device of this application is continuous. Based on the designed transmission ratio, the gear reduction mechanism 100 achieves the effect of reducing and amplifying torque, thereby providing high torque power to the rocker arm component 210. The rocker arm component 210 then converts the rotational motion into the linear motion of the sliding component 220, ensuring uninterrupted power transmission.

[0037] It is understandable that the specific implementation of the combination of crank-slider mechanism 200 and reduction mechanism can be adjusted according to actual usage requirements.

[0038] In some embodiments, the swing arm is directly connected via a cycloidal pinwheel. This cycloidal pinwheel, a speed reduction structure, directly connects its output shaft 110 to the swing arm, allowing the swing arm to move the slider without additional parts.

[0039] In other embodiments, it can also be configured as a double swing arm + gear set structure, with two swing arms connected to form a parallelogram structure, and a small gear set for deceleration. When the swing arm rotates, the slider moves accordingly, which can also achieve the technical effect required by the above mechanism.

[0040] It is understandable that the crank-slider mechanism 200 and the reduction mechanism can also be obtained by combining other commonly used mechanical structures, which will not be described in further detail here.

[0041] However, it should be understood that the crank-slider mechanism 200 proposed in this application comprises a rocker arm component 210, a sliding component 220, and a first guide component 230. Combined with the gear reduction mechanism 100, this arrangement ensures a simpler installation, easier maintenance, and greater adaptability. Its reduction ratio, rocker arm stroke, and other parameters can more accurately match requirements. Alternative solutions may require additional parameter adjustments for adaptation, resulting in slightly less flexibility. Furthermore, the power transmission in this application is more direct. While the cycloidal pinwheel reduction mechanism directly connecting to the rocker arm is also simple, this application achieves higher efficiency by directly linking the rocker arm with a more suitable gear meshing method, reducing power loss in intermediate transmission links.

[0042] The following will combine Figures 1 to 3 The transmission device disclosed in the embodiments of this application will be explained and described in detail.

[0043] It is understandable that the connection design of the swing arm component 210 is crucial to achieving higher transmission efficiency between the crank-slider mechanism 200 and the gear reduction mechanism 100. In some embodiments of this application, the sliding component 220 is provided with a second guide component 240, and the other end of the swing arm component 210 is provided with a hinge portion 211. The other end of the swing arm component 210 is slidably connected to the sliding component 220 via the hinge portion 211 on the second guide component 240.

[0044] It is understandable that by limiting the swing of the swing arm component 210 and decomposing the power input to the sliding component 220 through the second guide component 240, on the one hand, the other end of the swing arm component 210 can slide along the second guide component 240 based on the hinge part 211, and on the other hand, the power is output to the sliding component 220 so that it can be driven to move the first guide component 230, making the overall structural design more reasonable.

[0045] In some embodiments, the second guide member 240 includes a guide groove, and the hinge portion 211 is slidably disposed on the guide groove.

[0046] For example, the guiding direction of the first guide member 230 is perpendicular to the guiding direction of the second guide member 240. It can be understood that by decomposing the driving force from the swing of the swing arm member 210 into two driving forces with perpendicular directions, the sliding member 220 can make linear displacement along the guide of the first guide member 230, thereby improving the motion accuracy.

[0047] Specifically, the first guide component 230 guides in a horizontal direction, and the second guide component 240 guides in a vertical direction.

[0048] For example, the hinge portion 211 is a deep groove ball bearing. It is understood that the deep groove ball bearing can reduce friction, making the movable connection between the rocker arm portion 210 and the second guide portion 240 smoother and more unobstructed.

[0049] It is understandable that the gear reduction amplifies the torque through a specific transmission ratio and directly powers the swing arm mechanism. The swing arm converts the rotational motion into the linear motion of the slider through a continuous power transmission path and matching relationship. Through the gear torque amplification and the swing arm lever arm design, the output force of the slider is higher than that of a pure slider mechanism.

[0050] In some embodiments of this application, a groove 231 is formed on the first guide member 230, and a sliding end 221 is provided on the sliding member 220. The sliding member 220 is slidably connected to the first guide member 230 by means of the sliding end 221 being slidably disposed on the groove 231. It can be understood that the sliding connection between the groove 231 and the sliding end 221 results in low motion conversion loss and ensures overall transmission efficiency.

[0051] In some embodiments, a component for reducing friction and further improving transmission accuracy may be provided between the sliding end 221 and the slide groove 231. For example, a friction bearing may be provided between the sliding end 221 and the slide groove 231. Specifically, the friction bearing may be provided on at least one of the sliding end 221 or the slide groove 231. By cooperating with the high-precision slide groove 231, the overall transmission efficiency can be further improved.

[0052] In some embodiments, the sliding component 220 is a slider with multiple mounting positions for mounting components, enabling the mounted components to achieve high-precision linear displacement. The sliding end 221 is a protrusion, and the sliding end 221 and the sliding component 220 can be configured as an integral or separate structure according to actual needs.

[0053] In some embodiments of this application, the gear reduction mechanism 100 includes a driving gear 120 and a driven gear 130. The driving gear 120 is used to connect to the input shaft, and the driven gear 130 is used to coaxially fix the output shaft 110. The output shaft 110 is rigidly connected to the swing arm component 210. The driving gear 120 and the driven gear 130 mesh and drive each other, so that the output shaft 110 can drive the swing arm component 210 to swing synchronously by rotating. It can be understood that the gear reduction mechanism 100 and the swing arm mechanism are coaxial and integrated. The output shaft 110, which is located on the driven gear 130, directly serves as the input shaft for the swing arm power, and one end of the swing arm is rigidly fixed to the shaft to achieve synchronous rotation and swinging, forming an integrated structure without additional connecting parts.

[0054] In some embodiments, adjusting the gear ratio can change the torque, and adjusting the swing arm length can change the slider displacement and output force, adapting to various working conditions. For example, the number of teeth on the driving gear 120 is less than the number of teeth on the driven gear 130, thereby achieving the effect of speed reduction and torque increase. For example, both the driving gear 120 and the driven gear 130 are spur gears, thereby ensuring the accuracy of the gear transmission.

[0055] The transmission device of this application embodiment is described in detail below with reference to a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0056] See Figures 1 to 3 As shown, the transmission device of this embodiment provides a gear reduction-oscillating crank-slider composite transmission mechanism. By deeply integrating the gear reduction mechanism 100 and the oscillating crank-slider mechanism 200, an integrated transmission system with coordinated "reduction and torque increase-motion conversion" is formed. Its structure is formed by integrating the gear reduction module and the oscillating crank-slider module through "collinear shafts and integrated components".

[0057] Specifically, the gear reduction module includes a driving gear 120 and a driven gear 130, both of which are standard spur gears. The driving gear 120 is connected to the input shaft, and the driven gear 130 is coaxially fixed to the output shaft 110. The output shaft 110 also serves as the power input shaft for the slider module. The swing-type crank slider module includes a swing arm, a slider, a slide groove 231, and a hinge bearing. One end of the swing arm is rigidly fixed to the output shaft 110 of the driven gear 130, and the other end is embedded in the slide groove 231 through a low-friction deep groove ball bearing, moving linearly along the slide groove 231. There are no additional intermediate connecting parts between the swing arm and the slider, resulting in a compact structure.

[0058] The mechanism's "torque amplification-motion conversion" process includes: when the input shaft rotates, the driving gear 120 drives the driven gear 130 for transmission. The swing arm input shaft and driven gear are rigidly fixed, and the swing arm swings synchronously with the driven gear 130. When swinging in one direction, it drives the slider to make linear displacement. The amplified torque from the gears directly acts on the swing arm to overcome phenomena such as excessive slider load, and the power transmission is seamless. Compared to traditional single mechanisms, when the torque amplification of the gear reduction in this application is a specific factor, the output force under the same input force is increased by a specific factor compared to a pure slider mechanism.

[0059] Furthermore, the low-friction bearings, combined with the high-precision slide groove 231, result in low motion conversion losses and higher overall transmission efficiency compared to split mechanisms. No additional adaptation structures are required; the torque can be changed by adjusting the gear ratio between the driving and driven wheels, and the relationship between displacement and output force can be changed by adjusting the length of the swing arm. This allows for adaptation to various working conditions, resulting in greater integration and adaptability, and outstanding practicality in the field of mechanical transmission.
