Description

Technical Field

[0001] This utility model relates to the field of woodworking speed reducer technology, and in particular to a woodworking machine. Background Technology

[0002] Current woodworking machine equipment encompasses a reducer housing and the integrated gear reduction system. The core components of this system include a planetary carrier, planetary shafts, and an input shaft serving as the power input hub, employing a precision three-stage planetary gear reduction design. However, traditional woodworking reducers generally utilize a transmission scheme combining worm gears and spur gears. In actual operation, this structure suffers from significant sliding friction during worm gear meshing, leading to a substantial increase in internal temperature. This not only reduces transmission efficiency but also accelerates gear surface wear and aging. As gear wear intensifies, the sealing structure is prone to failure due to thermal expansion and material fatigue under prolonged high-speed operation, significantly increasing the risk of lubricant leakage. Oil leakage not only pollutes the working environment but also directly affects the stability of transmission accuracy, ultimately causing a significant negative impact on the processing quality of woodworking products. Against this backdrop, effectively improving the operational stability of woodworking machine equipment, extending the lifespan of key components, and controlling temperature rise and oil leakage have become critical technical bottlenecks and key research directions that the industry urgently needs to overcome. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this invention is to provide a woodworking machine that solves the problem of excessive internal temperature during operation, leading to lubricant leakage.

[0004] To achieve this objective, the present invention adopts the following technical solution: a woodworking machine, comprising a power component, a reduction transmission component, and an output component;

[0005] The output end of the power component is connected to a first gear;

[0006] The speed reduction transmission assembly includes a first housing and a first transmission component and a speed reduction gear installed inside the first housing. The two ends of the first transmission component are respectively hinged to the two inner walls of the first housing. The first transmission component includes a gear portion and a bevel gear portion installed at the end of the gear portion. The bevel gear portion meshes with the first gear.

[0007] The reduction gear is located below the first transmission member, and its two ends are respectively hinged to the two inner walls of the first housing. The reduction gear meshes with the gear section.

[0008] The output component is detachably mounted below the reduction gear assembly. The output component is provided with a second gear. The output component is fixed below the reduction gear assembly, and the second gear meshes with the reduction gear.

[0009] Preferably, the first gear is an arc-tooth bevel gear.

[0010] Preferably, the reduction gear is provided in multiple sets, which are staggered front and rear, and all sets of reduction gears mesh with the gear section.

[0011] Preferably, the gear portion is a helical gear.

[0012] Preferably, the number of teeth in the gear section is less than the number of teeth in the reduction gear.

[0013] Preferably, the first outer shell and the front and rear sides each have a first mounting portion protruding from them, and the first mounting portion is provided with a screw hole;

[0014] The top of the output component is provided with a second mounting part on the front and rear sides respectively, and the second mounting part is provided with a through hole.

[0015] The screw passes through the through hole and engages with the screw hole of the first mounting part for connection and fixation.

[0016] Preferably, the power assembly includes a second housing, a motor, and a connecting shaft. The second housing is fixed to one side of the first housing, the motor is installed inside the second housing, the output end of the motor is connected to the connecting shaft for transmission, and the first gear is installed on the connecting shaft.

[0017] Preferably, the first outer shell and the second outer shell are integrally formed.

[0018] Preferably, the assembly also includes an installation component, which includes a first plate and a second plate perpendicularly connected to the first plate. The first plate is connected to the power component for transmission. The second plate has multiple mounting holes, and multiple sets of reinforcing ribs are connected between the first plate and the second plate.

[0019] One of the above technical solutions has the following advantages or beneficial effects: In this utility model, the rolling meshing between the gear teeth results in a friction coefficient far lower than that between worm gears and worm shafts. This significantly reduces the heat generated by mechanical friction at its source, thereby effectively controlling the operating temperature inside the reducer. The lower temperature directly slows down the aging rate of the lubricating oil and significantly reduces wear on the gear surface. The gear transmission efficiency is much higher than that of worm gear transmission. Higher transmission efficiency means less energy loss, and this saved energy is ultimately dissipated as heat, further helping to reduce the system temperature rise. At the same time, stable gear meshing ensures the smoothness of power transmission and reduces impact loads. Attached Figure Description

[0027] like Figures 1-2 As shown, a woodworking machine includes a power component 1, a reduction transmission component 2, and an output component 3;

[0028] The output end of the power component 1 is connected to a first gear 14;

[0029] The speed reduction transmission assembly 2 includes a first housing 21 and a first transmission member 23 and a speed reduction gear 22 installed inside the first housing 21. The two ends of the first transmission member 23 are respectively hinged to the two inner walls of the first housing 21. The first transmission member 23 includes a gear part 231 and a bevel tooth part 232 installed at the end of the gear part 231. The bevel tooth part 232 meshes with the first gear 14.

[0030] The reduction gear 22 is located below the first transmission member 23. The two ends of the reduction gear 22 are respectively hinged to the two inner walls of the first housing 21. The reduction gear 22 meshes with the gear part 231.

[0031] The output component 3 is detachably installed below the reduction gear 2. The output component 3 is provided with a second gear 31. The output component 3 is fixed below the reduction gear 2, and the second gear 31 meshes with the reduction gear 22.

[0032] To better address the problem of excessive internal temperature and lubricant leakage during woodworking machine operation, this invention employs a multi-stage gear transmission structure, replacing the original worm gear pair, with gear section 231 and reduction gear 22, and bevel gear section 232 and first gear 14. Firstly, this drives the first gear 14 to rotate, and the first gear 14 meshes with the bevel gear section 232 (the first gear 14 and the bevel gear 232...). Figure 2 (The teeth are not depicted in the diagram). This drives the bevel gear 232 to rotate with its fixed gear 231. Below the gear 231, a reduction gear 22 meshes. The reduction gear 22 meshes with the second gear 31, thereby driving the output component 3 to work. In different working environments, different woodworking output components 3 can be replaced. For example, when polishing, the output component 3 can be replaced with a square planer. Simply mesh the second gear 31 of the square planer with the reduction gear 22 to adapt to different working environments.

[0033] Because this invention relies on rolling meshing between gear teeth, the coefficient of friction is much lower than the sliding friction between worm gears. This significantly reduces the heat generated by mechanical friction, thereby effectively controlling the operating temperature inside the reducer. The lower temperature directly slows down the aging rate of the lubricating oil and significantly reduces wear on the gear surfaces. Gear transmission efficiency is much higher than worm gear transmission. Higher transmission efficiency means less energy loss; this saved energy is ultimately dissipated as heat, further helping to reduce system temperature rise. Simultaneously, stable gear meshing ensures smooth power transmission and reduces impact loads.

[0034] Preferably, the first gear 14 is an arc-tooth bevel gear.

[0035] Since the first gear 14 serves as the power input and its input speed is relatively high, the resulting vibration is also significant. To improve the working stability of the woodworking machine, in one embodiment of this invention, the first gear 14 is configured as an arc-tooth bevel gear. The arc-tooth bevel gear can smoothly mesh and combine with the bevel gear transmission to form a low-vibration, low-noise first-stage transmission system. For woodworking machinery operating in noisy environments, this significantly improves the operator's working experience.

[0036] Preferably, the reduction gear 22 is provided in multiple sets, and the multiple sets of reduction gear 22 are staggered front and rear, and all the multiple sets of reduction gear 22 mesh with the gear part 231.

[0037] When a woodworking machine is cutting under heavy load, the reduction mechanism needs to withstand enormous torque. Traditional reduction transmission components 2 use individual gears meshing together to output power. The contact stress on the tooth surface and the bending stress at the tooth root of each individual gear are very high, easily causing overload damage. Therefore, in this invention, multiple sets of reduction gears 22 are provided, and each reduction gear 22 meshes with the gear section 231. This reduces the load on the reduction gears 22 to a fraction of the original, greatly reducing the contact stress on the tooth surface and the bending stress at the tooth root of each individual gear, fundamentally avoiding the risk of overload damage, and enabling the reduction transmission component 2 to cope with more demanding working conditions. Furthermore, the multiple sets of reduction gears 22 can mesh with multiple second gears 31 of the output component 3, improving the practicality of the output component 3.

[0038] Preferably, the gear section 231 is an arc-tooth bevel gear.

[0039] Since the gear section 231 needs to mesh with multiple sets of staggered reduction gears 22 simultaneously, when the gear section 231 is a helical gear, the helical tooth structure of the helical gear ensures that at any given time, each meshing pair is in a state of "partial tooth contact," thereby achieving smooth power transmission and seamless handover between multiple contact points. This ensures that torque is evenly distributed to each set of reduction gears 22, thus perfectly fulfilling the design intention of "power splitting."

[0040] Preferably, the number of teeth in the gear section 231 is less than the number of teeth in the reduction gear 22. In this invention, the primary task of this first-stage reduction, composed of the gear section 231 and multiple sets of reduction gears 22, is to initially reduce the rotational speed while proportionally amplifying the output torque, laying a solid foundation for possible further reduction and torque increase in the future.

[0041] Preferably, the first outer shell 21 has a first mounting portion 5 protruding from its front and rear sides, and the first mounting portion 5 is provided with a screw hole.

[0042] The top of the output component 3 is provided with a second mounting part 6 on the front and rear sides respectively, and the second mounting part 6 is provided with a through hole.

[0043] The screw passes through the through hole and engages with the screw hole of the first mounting part 5 to connect and fix it.

[0044] The first mounting part 5 and the second mounting part 6 are combined to form a flange-like structure. With the cooperation and fixation of screw holes and cylindrical pins, the output component 3 and the reduction transmission component 2 form a rigid whole, which can better resist the complex stress brought by the cutting load and improve the deformation resistance of the whole woodworking machine under heavy load.

[0045] Preferably, the power assembly 1 includes a second housing 11, a motor 12, and a connecting shaft 13. The second housing 11 is fixed to one side of the first housing 21. The motor 12 is installed inside the second housing 11. The output end of the motor 12 is connected to the connecting shaft 13 for transmission. The first gear 14 is installed on the connecting shaft 13.

[0046] Preferably, the first outer shell 21 and the second outer shell 11 are integrally formed.

[0047] The one-piece molded first shell 21 and second shell 11 facilitate user transportation and installation, improving the convenience of the woodworking machine.

[0048] Preferably, it also includes an installation component 4, which includes a first plate 41 and a second plate 42 perpendicularly connected to the first plate 41. The first plate 41 is connected to the power component 1 in a transmission manner. The second plate 42 has a plurality of mounting holes 421. A plurality of reinforcing ribs 43 are connected between the first plate 41 and the second plate 42.

[0049] In some embodiments, the woodworking machine needs to be fixed, therefore the mounting assembly 4 is provided. When installing and fixing the woodworking machine, the second plate 42 can be fixed in the corresponding location, and then secured by bolts passing through the mounting holes 421. Since the woodworking machine connected to the first plate 41 in the mounting assembly 4 is relatively heavy, in order to better maintain the connection rigidity between the first plate 41 and the second plate 42, multiple sets of reinforcing ribs 43 are provided between the first plate 41 and the second plate 42 to improve the connection strength between them.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
