[0002] With the rapid development of information technology and the continuous improvement of office automation, printers have become indispensable equipment in offices, homes and various commercial environments. During the operation of a printer, the gear transmission system, as a key component, undertakes the important functions of transmitting power and realizing precise motion control. Existing printer paper feeding gears, printhead drive gears, etc., generally use plastic gears for transmission.

[0003] The existing application number is CN201620824226.8. This utility model relates to the technical field of motorcycle parts, and more specifically, to a high-strength plastic gear, including a main shaft and an outer gear ring placed around the main shaft. The main shaft has a central hole. The main shaft includes an outer ring for mounting the outer gear ring and an inner ring for opening the central hole. The outer ring and the inner ring are connected by an annular skeleton ring. The annular skeleton ring includes an outer connecting part connected to the outer ring and an inner connecting part connected to the inner ring. The outer connecting part and the inner connecting part are connected by a reinforcing bridge plate. The outer wall of the outer connecting part is arc-shaped with an arc of π / 2. The outer wall of the inner connecting part is arc-shaped with an arc of 60°. This utility model has a reasonable and simple structure, strong practicality, and the main shaft has strong compressive strength.

[0004] Based on the above, the plastic gears of existing printers are prone to wear and tear due to friction between the paper feed roller and irregular paper during prolonged use. Over time, worn-out gears may develop broken teeth. If users fail to notice the broken teeth in time, the malfunction may worsen, resulting in economic losses. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a novel plastic gear for printers that can reduce noise and vibration. This addresses the issue that existing printer plastic gears are prone to wear and tear during prolonged use due to friction between the paper feed roller and irregular paper. Over time, worn-out plastic gears may develop broken teeth. If users fail to notice broken teeth in time, the malfunction can worsen, leading to economic losses.

[0006] The purpose and effect of this utility model, a novel plastic gear for printers that can reduce noise and vibration, are achieved by the following specific technical means:

[0007] A novel plastic gear for printers, capable of noise reduction and vibration damping, includes a first gear component, a second gear component, a connecting bolt, a vibration damping and noise reduction component, a lubrication mounting cover, a lubrication connection mechanism, and a noise reduction and vibration damping mechanism. The second gear component is fixedly connected above the first gear component. The connecting bolt is inserted into the middle position of the first and second gear components. The vibration damping and noise reduction component is fixedly connected to the upper inner side of the first gear component, and its outer periphery is covered with a sound-insulating cotton structure. Two sets of lubrication mounting covers are provided, and the two sets of lubrication mounting covers are respectively fixedly connected to the outer sides of the first and second gear components. The lubrication connection mechanism is located on the outer side of the first and second gear components. The noise reduction and vibration damping mechanism is located on the inner side of the vibration damping and noise reduction component.

[0008] Furthermore, the lubrication connection mechanism includes: a lubrication storage tank and a lubrication contact microgroove; two sets of lubrication storage tanks are provided, which are respectively opened on the outer side of the first gear and the second gear, and the interior of both sets of lubrication storage tanks is filled with lubricating oil; multiple sets of lubrication contact microgrooves are provided, which are respectively opened on the outer periphery of the first gear and the second gear, and the inner side of the multiple sets of lubrication contact microgrooves is connected to the interior of the lubrication storage tank.

[0009] Furthermore, the lubrication connection mechanism also includes: a first connector and a second connector; the first connector is provided in multiple sets, each set of the first connectors being a cylindrical structure, and the multiple sets of the first connectors being fixedly connected to the upper end of the first gear component; the second connector is provided in multiple sets, each set of the second connectors being a cylindrical structure, the multiple sets of the second connectors being fixedly connected to the lower part of the second gear component, and the multiple sets of the second connectors being inserted into the interior of the first connector.

[0010] Furthermore, the lubrication connection mechanism also includes: contact metal sheets; multiple sets of contact metal sheets are provided, each set of contact metal sheets is a thin metal sheet structure, and the multiple sets of contact metal sheets are respectively embedded in the tooth profile portion of the first gear component and the second gear component.

[0011] Furthermore, the noise reduction and vibration damping mechanism includes: a sound-absorbing groove; the sound-absorbing groove is a wavy groove structure, and the sound-absorbing groove is formed on the outer periphery of the vibration damping and noise reduction component.

[0012] Furthermore, the noise reduction and vibration damping mechanism also includes: vibration damping baffles; multiple sets of vibration damping baffles are provided, and the multiple sets of vibration damping baffles are respectively fixedly connected to the inner side of the vibration damping and noise reduction component, and the multiple sets of vibration damping baffles together form a honeycomb structure inside the vibration damping and noise reduction component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the design of a lubrication connection mechanism, firstly combines the first and second gear components using a combination connecting bolt, and then inserts the second connecting piece into the first connecting piece. This prevents relative rotation between the first and second gear components. The combined structure of the first and second gear components facilitates individual replacement. Simultaneously, during use, the lubricating oil inside the lubrication storage tank flows to the gear surface through lubrication contact microgrooves, reducing wear during transmission and making the transmission smoother and reducing noise. When the tooth root of the first or second gear component breaks, the two adjacent contact metal plates collide, producing a sound to alert the user and prompt timely gear replacement, preventing further damage to the printer and minimizing economic losses.

[0015] This utility model, through the setting of a noise reduction and vibration damping mechanism, achieves the consumption of noise generated by the gear through the sound-absorbing groove, while the sound-absorbing cotton on the surface of the vibration damping and noise reduction component absorbs the noise, reduces the transmission of noise, and makes the entire gear run quietly. At the same time, the honeycomb structure of the vibration damping baffle achieves the vibration damping effect during gear operation. Attached Figure Description
