Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical transmission technology, specifically a compact balance wheel anti-jamming transmission mechanism. Background Technology
[0002] In automotive transmission and timing systems, the balance wheel is a key component for converting rotational motion into reciprocating oscillation and adjusting transmission tension. It transforms the torque transmission of the power source into directional oscillating motion, directly affecting the transmission accuracy and operational stability of the vehicle.
[0003] The existing assembly of the balance wheel and transmission mechanism has certain gaps. During the operation of the car, some dust and road debris in the working environment can easily enter the mechanism through the gaps. Since the rigid fit clearance between the balance wheel and the transmission components is extremely small, the intruding foreign objects can easily accumulate on the mating surface. The foreign objects will fill the fit gap, which will significantly increase the relative rotational resistance between the balance wheel and the shaft, causing the swing to jam. In severe cases, it can easily embed into the surface of the balance wheel or the transmission shaft, forming a biting point, directly causing the balance wheel and the transmission mechanism to jam, making it unable to swing back and forth, and greatly increasing the equipment maintenance cost.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] Please see Figure 1-5 As shown, this utility model is a compact balance wheel anti-jamming transmission mechanism, comprising:
[0031] The transmission component includes a gear disk 11, a gear block 12, and a rotating shaft 13. The gear disk 11 is disposed on one side of the outer surface of the balance wheel, the gear block 12 is fixed on the outer wall of the gear disk 11, and the rotating shaft 13 is disposed on the outer side of the gear disk 11.
[0032] The anti-jamming component includes a fixed frame 21, a shielding frame 22, a dustproof net 23, an inner groove 24, a guide block 25, and a guide rod 26. The fixed frame 21 is fixed to the upper and lower parts of the outer surface of the rotating shaft 13, the shielding frame 22 is arranged between the two fixed frames 21, the dustproof net 23 is detachably connected to the inner walls of the fixed frame 21 and the shielding frame 22, the inner groove 24 is opened inside the fixed frame 21, the guide rod 26 is fixed to the inner surface of the inner groove 24, and the guide block 25 is arranged at the top and bottom of the shielding frame 22, and the middle part of the guide block 25 is slidably connected to the outside of the guide rod 26.
[0033] The fixed frame 21 and the shielding frame 22 form a closed cavity, completely surrounding the transmission components. Together with the dustproof net 23 that can be detachably installed on the inner wall, a physical barrier protection system is constructed. The dustproof net 23 can further intercept tiny dust particles that directly contact the transmission components, preventing foreign objects from getting stuck in the fit gap between the balance wheel and the shaft or in the gear meshing backlash. This prevents them from accumulating on the surface of the transmission components to form sludge or wear the mating surfaces, completely solving the problem of transmission interruption and component jamming caused by foreign objects, and significantly reducing equipment maintenance costs.
[0034] The dustproof net 23 further filters out tiny pollutants through its fine mesh. Even if a small amount of pollutants approaches the protective space with the airflow, they will be intercepted by the dustproof net 23, preventing pollutants from entering the movement gaps of the transmission components.
[0035] A slot 33 is provided at one end of the inner surface of the inner groove 24, and an insert 31 is provided at one end of the outer surface of the guide block 25. The insert 31 is inserted and connected to the inside of the slot 33.
[0036] By inserting and removing the plug 31 and the slot 33, the position of the pulled-out shield 22 is limited to prevent the shield 22 from moving accidentally during maintenance. This ensures that the protective structure remains stable during maintenance operations and avoids affecting maintenance efficiency or causing safety hazards due to the shaking of the shield 22.
[0037] An internal threaded ring 34 is provided on one side of the outer surface of the fixed frame 21. A threaded rod 35 is threadedly connected to the middle of the internal threaded ring 34. A handle 36 is fixedly connected to one side of the threaded rod 35.
[0038] Rotating handle 36 counterclockwise simultaneously drives threaded rod 35 to rotate, causing the other side of threaded rod 35 to separate from threaded hole 32, thus fixing the position of the pulled-out cover frame 22.
[0039] A threaded hole 32 is provided on one side of the guide block 25, and the other side of the threaded rod 35 is threaded into the inside of the threaded hole 32;
[0040] Rotating handle 36 clockwise drives threaded rod 35 to rotate simultaneously, causing the other side of threaded rod 35 to be threaded into threaded hole 32, thus fixing the position of the closed frame 22.
[0041] One end of the outer surface of the first toothed disc 11 is provided with a second toothed disc 14, and the outer wall of the second toothed disc 14 is provided with a tooth groove 15, and the toothed block 12 and the tooth groove 15 are meshed and connected.
[0042] A rotating shaft 16 is provided on one side of the outer surface of the gear disk 14, and a motor 17 is fixedly connected to the outer side of the rotating shaft 16.
[0043] The drive motor 17 in the starting device converts electrical energy into mechanical energy and outputs torque to the rotating shaft 16 connected to its power end. When the motor 17 drives the rotating shaft 16 to rotate around its own axis, it will directly drive the gear disk 14 to rotate synchronously with the rotating shaft 16. When the gear disk 14 rotates, its tooth blocks 12 will successively embed into the tooth grooves 15 to form a stable gear meshing connection structure. When the gear disk 14 rotates, the tooth blocks 12 will generate circumferential thrust on the tooth grooves 15, transmitting the rotational torque and motion state to the gear disk 11. At the same time, the rotating shaft 13 provides rotational support for the gear disk 11, ultimately driving the gear disk 11 to rotate synchronously with the rotation direction of the gear disk 14, which will directly drive the balance wheel to perform circular motion around the rotating shaft 13.
[0044] Working principle:
[0045] First, the rotating handle 36 drives the threaded rod 35 connected to it to rotate synchronously. Since the threaded rod 35 and the threaded hole 32 on the guide block 25 are threadedly engaged, the threaded rod 35 will move along the axis of the threaded hole 32 when it rotates, eventually separating the threaded rod 35 from the threaded hole 32 and releasing the locking state between the fixed frame 21 and the shielding frame 22. Then, the shielding frame 22 is pulled to both ends. At this time, the guide block 25 on the shielding frame 22 will slide linearly along the guide rod 26 inside the inner groove 24. The transmission components that were originally surrounded are gradually exposed, providing sufficient space for maintenance operations. The insert block 31 on the guide block 25 will be inserted into the slot 33 inside the inner groove 24 at the same time to limit the position of the shielding frame 22 after it is pulled out.
[0046] This step forms a closed-loop working mechanism through the process of protection-unlocking-opening-fixing: Under normal conditions, the fixed frame 21, the shielding frame 22, and the dustproof net 23 work together to achieve dust protection. During maintenance, the transmission handle 36, the threaded rod 35, and the threaded hole 32 are responsible for unlocking, the guide rod 26 and the guide block 25 ensure smooth opening, and the insertion block 31 and the insertion hole fix the position, which satisfies both the reliability of protection and the convenience of maintenance.
[0047] Please see Figure 1-5As shown, this embodiment, based on the above embodiment, further includes:
[0048] The tight-fitting component includes a rubber clamping frame 41, a rotating rod 42, a support block 43, and a rotating ring 44. The support block 43 is fixed to the outside of the fixed frame 21, the rotating rod 42 is disposed between the two support blocks 43, the rotating ring 44 is rotatably connected to the outside of the rotating rod 42, and the rubber clamping frame 41 is fixed to one side of the rotating ring 44.
[0049] The operator applies a rotational force to the rotating ring 44, causing the rotating ring 44 to rotate around the axis of the rotating rod 42 outside of it, thereby causing the rubber clamping frame 41 to be clamped between the fixed frame 21 and the shielding frame 22.
[0050] The elastic properties of the rubber clamp 41 allow it to be tightly clamped in the outer splicing area of the shielding frame 22 and the fixed frame 21; the deformation capability of the rubber material can fill the tiny gap at the splicing of the two frames, while generating a continuous clamping force to ensure that the shielding frame 22 and the fixed frame 21 form a tight fit without gaps, blocking the path of pollutants from the splicing gap between the two frames into the protected space.
[0051] Working principle:
[0052] The operator applies a rotational force to the rotating ring 44, causing the rotating ring 44 to rotate around the axis of the rotating rod 42 outside of it. The rubber clamping frame 41 connected to the rotating ring 44 will rotate at the same time, gradually moving closer to the outer splicing position of the shielding frame 22 and the fixed frame 21, so that the rubber clamping frame 41 is clamped between the fixed frame 21 and the outside of the shielding frame 22.
[0053] This step maximizes the dust and impurity protection of the transmission components.
