Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical transmission, and particularly relates to a connecting rod-driven gear shaft and right-angle crank transmission system. Background Art

[0002] In modern mechanical transmission systems, as a key link for energy transfer and motion control, gear transmission is widely used in various industrial equipment, automated production lines, and precision instruments. Traditional gear transmission systems usually use direct drive or simple chain and belt drive methods to achieve power transmission. However, with the development of industrial demands towards high efficiency, compactness, and multi-functionality, the traditional transmission methods gradually show their limitations in some application scenarios, such as large volume, low efficiency, and difficulty in achieving complex motion patterns.

[0003] Especially when it is necessary to convert rotational motion into linear motion or other forms of intermittent motion, existing solutions often rely on complex mechanical structures or additional conversion devices, which not only increase the overall complexity and cost of the system, but also may lead to higher failure rates and maintenance requirements. In addition, in some specific application scenarios, such as those requiring high-precision synchronous operation or multi-axis linkage, how to effectively achieve coordinated actions between multiple actuators has become an urgent problem to be solved.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0009] Preferably, the above technical solution further comprises a spring bolt installed between the right-angle handle and the second rotating shaft, and used for assisting the second rotating shaft to reset to the initial position when it leaves the contact section of the right-angle handle.

[0010] Preferably, in the above technical solution, the phases of the two first gear linkage devices on the same side of the upper and lower gear sets are deviated by 90 degrees, and the two second gear linkage devices are driven alternately to ensure transmission continuity.

[0020] Technical effect: Stability: The rigid connection ensures the relative rest of the inner frame and the outer frame, and avoids power loss caused by frame displacement during the transmission process.

[0021] Accurate positioning: The gear shaft mounting seats achieve high-precision alignment of the gear set axes through mechanical limits, reduce gear meshing errors, and improve transmission efficiency.

[0022] Two sets of gear sets 3 distributed vertically Structure: Each set of gear sets 3 includes a power output gear 3a and two transmission gears 3b. The power output gear 3a and the two transmission gears 3b within the same set of gear sets 3 are arranged side by side with a certain gap between them. The power output gear 3a of the upper gear set 3 meshes with the outer transmission gear 3b of the lower gear set 3, and the middle transmission gear 3b of the upper gear set 3 and the outer transmission gear 3b mesh with the middle transmission gear 3b of the lower gear set 3 at the same time. The outer transmission gear 3b of the upper gear set 3 meshes with the middle transmission gear 3b and the outer power output gear 3a of the lower gear set 3 at the same time, forming power transmission.

[0023] Technical effects: Efficient power transmission: Direct power transmission is achieved through gear meshing, and the rigid characteristics of mechanical meshing are used to reduce energy loss.

[0024] Compact layout: The side-by-side distribution design shortens the power transmission path, reduces space occupancy, and is suitable for compact application scenarios.

[0025] Four groups of first gear linkage devices 4 are symmetrically distributed in pairs on both sides of the two sets of gear sets 3.

[0026] Structure: Each set of devices includes a first rotating shaft 4a and a first lever 4b.

[0027] First rotating shaft 4a: It is fixedly connected to the power output gear 3a and the transmission gear 3b respectively, receiving the power of the gear set.

[0028] First lever 4b: It is rotationally connected to the first rotating shaft through a second rotating shaft 8, converting the rotational motion into a swinging motion. The first lever 4b connects the transmission shaft of the transmission gear 3b and the power output shaft of the power output gear 3a.

[0029] Technical effects: Motion conversion: Through the linkage of the rotating shaft and the lever, the rotational motion of the gear is converted into a swinging output, realizing flexible conversion of the motion form.

[0030] Phase complementary design: Based on the rotating shaft of the gear set, the rotational phases of the two sets of first gear linkage devices are relatively deflected by 180°; the phases of the two sets of first gear linkage devices on the same side of the upper and lower gear sets are deflected by 90°, alternately driving the two sets of second gear linkage devices to ensure the continuity of power transmission.

[0031] Four groups of second gear linkage devices 5. The second rotating shaft 5a and the second pull rod 5b of the second gear linkage device are on the outside of the outer frame, and the right-angle dial handle and the live-edge crank are on the inside of the outer frame, corresponding to the four groups of first gear linkage devices 4 respectively.

[0032] The structure of the second gear linkage device 5: Each set of the device includes a second rotating shaft 5a, a second pull rod 5b, a right-angle handle 6 and a movable edge turn.

[0033] The second rotating shaft 5a passes through the outer frame through the first rotating shaft 7 and extends to the inside of the inner frame, and is fixedly connected to the right-angle handle.

[0034] Right-angle handle 6 : The contact surface is a right-angle groove structure, which matches the second rotating shaft 8 .

[0035] Technical effects: Spatial adaptability: Through the cross-frame design of the first rotating shaft 7, power linkage between the inner and outer frames is achieved, thereby expanding the transmission range.

[0036] Key details and technical effects Second axis 8 design: Technical effect: Extend the contact stroke and enhance the stability of cooperation with the right-angle handle.

[0037] Spring bolt 9 design: Reset function: The spring bolt is installed between the right-angle handle and the second shaft to assist in resetting to the initial position when the second shaft is out of the contact interval of the right-angle handle.

[0038] Technical effect: Ensure that the system quickly returns to its initial position in the non-working range, maintain transmission continuity and reduce mechanical shock.

[0039] Live Edge 10 Design: One end of the movable edge turn 10 is rotatably connected to the second rotating shaft 8, and the other end is rotatably connected to the first rotating shaft 7; The design of the movable edge turn 10 and the right-angle handle 6: one end of the movable edge turn 10 is rotated to connect with the right-angle handle 6 to the second rotating shaft 8, and the other end is rotated to connect with the first rotating shaft 7; First lever design and second pull rod design: The first lever 4b is rotatably connected to the first rotating shaft through the second rotating shaft 8 to convert the rotating motion into the swinging motion. The first lever 4b connects the transmission shaft of the transmission gear 3b and the power output shaft of the power output gear 3a.

[0040] The second pull rod 5b is connected to the first rotating shaft 7 and the second rotating shaft 5b to achieve a stable operation design.

[0041] Working principle and comprehensive technical effects Power transmission path: the straight-angle lever is in the clockwise direction of 90° or counterclockwise direction of 270° - the straight-angle lever drives the first rotating shaft to the second pull rod through the movable edge and the second rotating shaft and the gravity carried by the first lever - so that the pulling force is reciprocated to rotate the gear set.

[0042] Phase complementary transmission: Based on the rotation axis of the gear set, the rotation phases of the two sets of first gear linkage devices are relatively deflected by 180°; the phases of the two sets of first gear linkage devices on the same side of the upper and lower gear sets are deflected by 90°, alternately driving the two sets of second gear linkage devices to ensure the continuity of power transmission. When one side of the second rotating shaft 8 rotates counterclockwise, the other side is in the reset state and rotates clockwise relative to the gear set. The first lever drives the right-angle dial handle 6 through the live-edge crank to alternately drive the second gear linkage device 5.

[0043] The power output gear 3a and the transmission gear 3b between the upper and lower gear sets 3 are meshed with each other in a staggered manner to form power transmission.

[0044] Technical effects: Continuous transmission: The phase difference design eliminates the transmission gap and realizes a non-stop power output, which is suitable for scenarios that require stable and continuous motion (such as an automated production line).

[0045] Load balancing: The devices on both sides exert force alternately, dispersing the peak load and extending the service life of the system.

[0046] Overall advantages: High efficiency: The combination of mechanical meshing and the lever principle.

[0047] Adaptability: By adjusting the gear module and the lever length, it can be adapted to different rotational speeds and torque requirements.
