Description

Technical Field

[0001] This application relates to the field of mechanical transmission, and in particular to a drive assembly for an ice maker. Background Technology

[0002] Ice makers have wide applications in modern life and industrial production, providing a convenient supply of ice and meeting the ice needs of many industries such as catering, medical care, and cold chain transportation. As people's demands for ice-making efficiency and quality continue to increase, the various components of ice makers are also constantly developing and improving to adapt to the diversified needs of the market. A high-performance ice maker can not only increase ice-making speed but also reduce energy consumption and extend the equipment's lifespan. Especially in commercial ice-making scenarios, efficient and reliable ice makers play a crucial role in reducing operating costs and improving service quality for businesses. To achieve better ice-making results, the drive component of the ice maker, as one of the core components, has always been a key focus of industry research and development. The drive motors in existing ice makers are usually relatively simple in design. To drive the ice maker, ordinary motors are generally used as the driving force source. During startup and operation, these ordinary motors mainly rely on the conversion of electrical energy into mechanical energy, which drives the rotation of the motor shaft to move the rotating parts and other components of the ice maker. Some ice makers combine a regular motor with a belt drive system, using the friction of the belt to transmit the motor's power to the ice-making mechanism. Others use chain drives, where the chain and sprockets transmit the motor's rotational power to achieve the ice-making process. However, existing ice maker drive components have significant drawbacks. The driving force of current drive motors is relatively insufficient, resulting in unstable output and frequent jamming during operation. This not only leads to low ice-making efficiency but may also affect the quality of the ice. Furthermore, existing ice maker drive components generate excessive noise during operation, easily producing abnormal sounds. In commercial settings or noise-sensitive environments, this can cause serious interference and reduce the user experience. Utility Model Content

[0003] In order to ensure the driving stability of the ice maker, improve the ice-making efficiency, and reduce the noise generated during the operation of the ice maker, this application provides an ice maker driving component.

[0004] This application provides a drive assembly for an ice maker, including a drive base, a power input assembly, and a power output assembly. The power input assembly includes a brushless motor and a motor housing on which the brushless motor is mounted. The motor housing is integrally formed with the drive base. The output shaft of the brushless motor passes through the drive base and is equipped with helical gears. The power output assembly includes a gear assembly and a connecting assembly. The gear assembly is mounted to the drive base via the connecting assembly. All gears in the gear assembly are equipped with helical gears identical to those on the output shaft. The output shaft drives the gears of the power output assembly to rotate. By adopting the above technical solution, a brushless motor is used instead of an existing ordinary motor as the driving force source. The brushless motor has better driving performance and can provide more sufficient and stable driving force. The integrally formed design of the motor housing and drive base enhances the stability of the overall structure, making power transmission smoother and reducing shaking and jamming during operation. The output shaft passes through the drive housing and is equipped with a helical gear. The gears in the power output assembly also feature the same helical gears. This helical gear meshing method allows the helical gears to gradually engage and disengage during meshing, reducing impact and making the transmission smoother. Furthermore, when the output shaft drives the gears in the power output assembly, it increases the contact area between the gears, making power transmission more uniform and further improving the stability of power transmission. Simultaneously, the more stable power transmission reduces friction and impact caused by unstable operation, thereby reducing noise and abnormal sounds during operation. In summary, this ice maker drive assembly significantly improves the stability and efficiency of the ice maker's operation, reduces jamming, improves ice-making quality, reduces noise interference, and enhances the user experience. Preferably, the helix angle of both the helical gear on the output shaft and the helical gear in the gear assembly is 20°-30°. By adopting the above technical solution, when the helix angle of both the helical gear on the output shaft and the helical gear in the gear assembly is set within the range of 20°-30°, the contact of the helical gear tooth surfaces is smoother during power transmission compared to other helix angle ranges. Because of the appropriate helix angle, the gear teeth gradually engage and disengage, rather than engaging all teeth abruptly like existing spur gears, thus greatly reducing impact force. Lower impact force means that the power from the brushless motor can be transmitted more stably from the output shaft to the gear assembly during power transmission, avoiding power loss and instability caused by excessive impact force, and reducing the probability of jamming during ice maker operation. Preferably, the gear module of the output shaft and the gear module in the gear assembly are both 1.125. By adopting the above technical solution, setting the gear module of the output shaft and the gear module in the gear assembly to 1.125 allows for a more uniform distribution of tooth surface contact stress and stronger torque during power transmission.A suitable module ensures moderate tooth thickness, avoiding both insufficient strength due to excessively thin teeth and unnecessary weight and cost increases due to excessively thick teeth. This reduces gear wear during meshing, extends gear life, and ensures stable power transmission from the output shaft to the gear assembly. Consequently, the ice maker drive assembly operates more stably, contributing to improved overall ice-making efficiency and quality. Preferably, the gear assembly includes a primary gear component, and the connecting assembly includes a first connecting shaft that passes through the primary gear component and is rotatably mounted on the drive seat. The primary gear component rotates synchronously with the first connecting shaft and meshes with the output shaft. The number of gears in the primary gear component is greater than the number of gears on the output shaft. By adopting the above technical solution, since the primary gear component meshes with the output shaft and its number of gears is greater than the number of gears on the output shaft, according to the gear transmission principle, when the output shaft with a smaller number of gears drives the primary gear component with a larger number of gears, a speed reduction and torque increase effect can be achieved. The power from the output shaft is transmitted to the primary gear assembly. The primary gear assembly amplifies the torque and outputs it through a first connecting shaft that rotates synchronously with it. The first connecting shaft passes through the primary gear assembly and is rotatably mounted on the drive seat, ensuring the stability of the transmission process. This not only allows the ice maker drive assembly to output more stable power, avoiding jamming and effectively improving the ice maker's ice-making efficiency and quality, but also, compared to existing ice maker drive assemblies, the increased torque reduces noise and abnormal sounds during operation, enhancing the user experience in commercial settings or noise-sensitive environments. Preferably, the gear assembly includes a primary gear assembly and a secondary gear assembly, and the connecting assembly includes a first connecting shaft and a second connecting shaft. The first connecting shaft passes through the primary gear assembly and is rotatably mounted on the drive seat. The primary gear assembly rotates synchronously with the first connecting shaft. The second connecting shaft is fixed to the drive seat and passes through the secondary gear assembly. The primary gear assembly meshes with the secondary gear assembly, and the secondary gear assembly meshes with the output shaft. The number of gears in the primary gear assembly is greater than the number of gears in the output shaft. By adopting the above technical solution, since the primary gear component rotates synchronously and is fixed to the first connecting shaft, when the output shaft of the brushless motor rotates, the helical gear on the output shaft drives the secondary gear component meshing with it to rotate, and the secondary gear component then drives the primary gear component meshing with it to rotate, thereby causing the first connecting shaft to rotate and output power. Because the number of gears in the primary gear component is greater than the number of gears on the output shaft, according to the gear transmission principle, it can play a role in reducing speed and increasing torque during power transmission, effectively solving the problem of insufficient driving force in existing drive motors, making the ice maker's output more stable, avoiding jamming, and improving ice-making efficiency and quality. At the same time, compared with existing belt or chain drives, this transmission structure can reduce noise and abnormal sounds generated during operation, improving the user experience in commercial venues or noise-sensitive environments.Preferably, the gear assembly includes a primary gear, a secondary gear, and a tertiary gear. The connecting assembly includes a first connecting shaft, a second connecting shaft, and a third connecting shaft. The first connecting shaft passes through the primary gear and is rotatably mounted on the drive seat. The primary gear rotates synchronously with the first connecting shaft. The second and third connecting shafts are both fixed to the drive seat. The second connecting shaft passes through the secondary gear, and the third connecting shaft passes through the tertiary gear. The primary gear meshes with the secondary gear, the secondary gear meshes with the tertiary gear, and the tertiary gear meshes with the output shaft. The number of gears in the primary gear is greater than the number of gears on the output shaft. By adopting the above technical solution, the ice maker drive assembly uses a gear assembly including a primary gear, a secondary gear, and a tertiary gear, and a connecting assembly including a first connecting shaft, a second connecting shaft, and a third connecting shaft. The first connecting shaft passes through the primary gear and is rotatably mounted on the drive seat. The primary gear rotates synchronously with the first connecting shaft. Simultaneously, the second and third connecting shafts are fixed to the drive seat and pass through the secondary and tertiary gears, respectively. When the output shaft of the brushless motor rotates, the tertiary gear meshes with the output shaft, driving the tertiary gear to rotate. The tertiary gear then drives the meshing secondary gear, which in turn drives the meshing primary gear, forming a multi-stage transmission. Since the number of gears in the primary gear is greater than the number of gears on the output shaft, according to the gear transmission principle, this multi-stage reduction transmission structure effectively increases torque, thus solving the problem of insufficient driving force in existing drive motors. This makes the ice maker's output more stable, avoids jamming, and improves ice-making efficiency and quality. Furthermore, compared to existing drive methods, this multi-stage transmission structure transmits power more smoothly, reducing vibration and impact, thereby reducing noise and abnormal sounds generated during operation and improving the user experience in commercial settings or noise-sensitive environments. Preferably, the secondary gear assembly includes a fixedly connected secondary pinion and a secondary large gear, with the secondary pinion coaxially positioned directly above the secondary large gear. The tertiary gear assembly includes a fixedly connected tertiary pinion and a tertiary large gear, with the tertiary pinion coaxially positioned directly below the tertiary large gear. The secondary pinion meshes with the primary gear assembly, the secondary large gear meshes with the tertiary pinion, and the tertiary large gear meshes with the output shaft. The number of gears in the primary gear assembly is greater than the number of gears on the output shaft. By adopting the above technical solution, the secondary gear assembly consists of a fixedly connected and coaxially positioned secondary pinion and secondary large gear, and the tertiary gear assembly consists of a fixedly connected and coaxially positioned tertiary pinion and tertiary large gear. The secondary pinion meshes with the primary gear assembly, the secondary large gear meshes with the tertiary pinion, and the tertiary large gear meshes with the output shaft. Furthermore, the number of gears in the primary gear assembly is greater than the number of gears on the output shaft.Due to the meshing transmission between different gears and the predetermined relationship between their numbers, multi-stage speed change and torque conversion are achieved during transmission. When the output shaft rotates, the power transmission of the ice maker is smoother through the progressive transmission of the primary, secondary, and tertiary gears. This avoids vibrations and impacts caused by unstable power in existing drive methods, thereby reducing noise and abnormal sounds during operation and improving the user experience in commercial settings or noise-sensitive environments. Preferably, the number of gears in the primary gear is greater than the number of gears in the secondary gear, and the number of gears in the secondary gear is greater than the number of gears in the tertiary gear. By adopting the above technical solution, progressive increases in speed and reasonable torque distribution can be achieved during multi-stage gear transmission, enabling the entire ice maker drive assembly to transmit power more efficiently and avoiding stuttering caused by unreasonable power transmission, thus effectively improving the ice-making efficiency of the ice maker. Simultaneously, the more stable and smooth power transmission reduces unnecessary friction and collisions between components, further reducing noise and abnormal sounds generated during the operation of the ice maker drive assembly and improving the user experience. Preferably, the number of gears in the third-stage pinion is greater than the number of gears in the second-stage pinion, and the number of gears in the second-stage pinion is greater than the number of gears in the output shaft. By adopting the above technical solution, since the number of gears in the third-stage pinion is greater than the number of gears in the second-stage pinion, and the number of gears in the second-stage pinion is greater than the number of gears in the output shaft, during power transmission, according to the gear transmission principle, the smaller gear driving the larger gear will have a speed-reducing and torque-increasing effect. When the output shaft transmits power to the second-stage pinion, the torque is increased to a certain extent. Then, the second-stage pinion drives the third-stage pinion to rotate, further increasing the torque. This allows the entire ice maker drive assembly to output greater driving force, preventing jamming during operation, improving the stability of the ice maker's operation, and thus improving ice-making efficiency and quality. At the same time, a more stable driving force also helps reduce noise and abnormal sounds caused by unstable power, improving the user experience. Preferably, the output end of the first connecting shaft is provided with a coupling for installing the rotating parts of the ice maker. By adopting the above technical solution, since a coupling for mounting the rotating part of the ice maker is provided at the output end of the first connecting shaft, the coupling can effectively compensate for any axial, radial, and angular misalignments that may exist between the first connecting shaft and the rotating part of the ice maker, making the connection between the two more stable and reliable. In this way, when the output shaft of the brushless motor drives the gears of the power output component to rotate, power can be transmitted more smoothly and efficiently from the first connecting shaft to the rotating part of the ice maker, avoiding power transmission losses caused by unstable connections. This improves the overall operating efficiency of the ice maker, reduces the occurrence of jamming, and also reduces noise and abnormal sounds generated during operation, improving the ice-making quality of the ice maker and the user experience.

[0005] In summary, this application includes at least one of the following beneficial technical effects:

[0006] 1. Because it uses a brushless motor as the power input, the brushless motor has a stronger driving force than the existing drive motor, which can effectively solve the problem of insufficient driving force of the existing drive motor, thus making the ice maker's operation output more stable, avoiding the occurrence of jamming, and thus improving ice making efficiency and quality.

[0007] 2. Because the motor housing of the power input component is integrally molded with the drive base, the overall structure and stability are enhanced. At the same time, both the output shaft and the gears of the power output component are helical gears. Helical gears have a large contact area and high overlap during transmission, which can reduce the noise and abnormal sounds generated during drive operation. Therefore, it can reduce the noise and abnormal sounds generated during drive operation and improve the user experience.

[0008] 3. By rationally designing the helix angle and gear module of the helical gear in the output shaft and gear assembly, a suitable helix angle can make the gear transmission smoother and reduce vibration and impact, while an appropriate gear module can ensure the strength matching between gears. This ensures the stability and reliability of power transmission and further improves the operating effect of the ice maker. Attached Figure Description

[0013] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0014] Example 1

[0015] Embodiment 1 of this application provides an ice maker drive assembly, which is described below. Figure 1 and Figure 2 It includes a drive base 1, a power input component 2, and a power output component 3. Both the power input component 2 and the power output component 3 are mounted on the drive base 1. The power input component 2 cooperates with the power output component 3 through the drive base 1, transmitting its output power to the power output component 3. The power output component 3 then outputs the power to the components of the ice maker, providing a stable and reliable driving force for the ice maker and avoiding the problems of insufficient driving force and unstable operation of existing drive components. Specifically, in this embodiment, the power input component 2 includes a brushless motor 21 and a motor housing 22 on which the brushless motor 21 is mounted. Compared to existing ordinary motors, the brushless motor 21 has higher efficiency, stronger driving force, and better stability. The motor housing 22 is typically a closed structure to protect the brushless motor 21 from external dust, moisture, and other factors. It is made of high-strength plastic, which is lightweight and has good heat dissipation. Specifically, in this embodiment, the motor housing 22 is integrally formed with the drive base 1, and the drive base 1 is also equipped with a cover 11. The power output component 3 is installed inside the drive base 1, and the cover 11 is placed over the drive base 1 to protect the power output component 3 within the drive base 1. This design enhances the structural strength and stability of the entire drive assembly and reduces noise and vibration caused by loosening between components. The output shaft 211 of the brushless motor 21 passes through the drive base 1, and a helical gear is provided on the output shaft 211. The helix angle of the helical gear is 20°-30°, and the gear module is 1.125. This helical gear design enables smoother power transmission and reduces impact and noise. (Refer to...) Figure 3 Specifically, the power output assembly 3 in this embodiment includes a gear assembly 31 and a connecting assembly 32. The gear assembly 31 is mounted on the drive base 1 via the connecting assembly 32. All gears in the gear assembly 31 are equipped with helical gears identical to those on the output shaft 211. These helical gears also have a helix angle of 20°-30° and a gear module of 1.125. This ensures good meshing between the output shaft 211 and the gear assembly 31, achieving effective power transmission. (Refer to...) Figure 3In this embodiment, the gear assembly 31 includes a primary gear 311, a secondary gear 312, and a tertiary gear 313. The connecting assembly 32 includes a first connecting shaft 321, a second connecting shaft 322, and a third connecting shaft 323. The first connecting shaft 321 is rotatably mounted on the drive seat 1. The second connecting shaft 322 and the third connecting shaft 323 are both fixed to the drive seat 1. In this embodiment, the primary gear 311 is a primary gear, and an annular washer structure is provided below the gear to suspend the primary gear on the surface of the drive seat 1, facilitating meshing with the secondary gear 312. The first connecting shaft 321 passes through the annular washer and the primary gear. The first connecting shaft 321 and the primary gear can rotate synchronously on the drive seat 1. The first connecting shaft 321 is rotatably connected to the drive seat 1 through a bearing to reduce frictional resistance during rotation. The primary gear 311 and the first connecting shaft 321 are fixed and rotate synchronously, and are fixed by a key connection to ensure that power can be accurately transmitted from the primary gear 311 to the first connecting shaft 321.

[0016] Reference Figure 3 In this embodiment, the secondary gear component 312 includes a coaxially arranged secondary large gear 3121 and secondary small gear 3122. The secondary large gear 3121 is located above the secondary small gear 3122. A second connecting shaft 322 passes through the secondary large gear 3121 and the secondary small gear 3122, and the secondary large gear 3121 and the secondary small gear 3122 can rotate synchronously. The tertiary gear component 313 includes a coaxially arranged tertiary large gear 3131 and tertiary small gear 3132. The tertiary large gear 3131 is located below the tertiary small gear 3132. A third connecting shaft 323 passes through the tertiary large gear 3131 and the tertiary small gear 3132, and the tertiary large gear 3131 and the tertiary small gear 3132 can rotate synchronously. Furthermore, the secondary large gear 3121 meshes with the output shaft 211, and the secondary large gear 3121 drives the secondary small gear 3122 to rotate synchronously. Since the secondary small gear 3122 meshes with the tertiary large gear 3131, the secondary small gear 3122 then drives the tertiary large gear 3131 to rotate. Then, the tertiary large gear 3131 synchronously drives the tertiary small gear 3132 to rotate. Since the tertiary small gear 3132 meshes with the primary gear, it drives the primary gear and the first connecting shaft 321 to rotate.

[0017] Furthermore, in this embodiment, the number of gears in the first-stage gear 311 is greater than the number of gears in the second-stage large gear 3121, the number of gears in the second-stage large gear 3121 is greater than the number of gears in the third-stage large gear 3131, the number of gears in the third-stage small gear 3132 is greater than the number of gears in the second-stage small gear 3122, and the number of gears in the second-stage small gear 3122 is greater than the number of gears in the output shaft 211. This design creates a more complex and refined transmission ratio, which increases torque output and improves the driving force of the ice maker. Specifically, a coupling for mounting the rotating parts of the ice maker is provided at the output end of the first connecting shaft 321. The function of the coupling is to transmit the power of the first connecting shaft 321 to the rotating parts of the ice maker. Common couplings include flexible couplings and rigid couplings. Flexible couplings can compensate for the relative displacement between the two shafts and buffer vibration and impact; this embodiment uses a rigid coupling, which has a higher torque transmission capacity and is suitable for occasions where the alignment accuracy of the two shafts is high. The implementation principle of this embodiment is as follows: A power input component 2 is formed by installing a brushless motor 21 within a closed motor housing 22. The motor housing 22 and the drive base 1 are integrally formed. The output shaft 211 of the brushless motor 21 passes through the drive base 1 and is equipped with a helical gear with a helix angle of 20°-30° and a module of 1.125. Next, a power output component 3 is manufactured, whose gear assembly 31 includes a primary gear 311, a secondary gear 312 (the secondary large gear 3121 and the secondary small gear 3122 are coaxially arranged on the second connecting shaft 322), and a tertiary gear 313 (the tertiary large gear 3131 and the tertiary small gear 3132 are coaxially arranged on the third connecting shaft 323). All gears in the gear assembly 31 are equipped with helical gears of the same specifications as the output shaft 211 to ensure good meshing. The power transmission route is: the output shaft 211 drives the secondary large gear... Gear 3121, secondary large gear 3121 drives secondary small gear 3122, secondary small gear 3122 drives tertiary large gear 3131, tertiary large gear 3131 drives tertiary small gear 3132, tertiary small gear 3132 drives primary gear and first connecting shaft 321 to rotate, and the number of gears at each stage is set to form a complex and fine transmission ratio to increase torque output; finally, a rigid coupling is set at the output end of the first connecting shaft 321 to transmit power to the rotating parts of the ice maker, thereby providing a stable and reliable driving force for the ice maker. Example 2

[0018] The difference between this embodiment 2 and embodiment 1 is that the gear assembly 31 includes a primary gear 311 and a secondary gear 312. The secondary large gear 3121 and the secondary small gear 3122 can rotate synchronously. The connecting assembly 32 includes a first connecting shaft 321 and a second connecting shaft 322. The first connecting shaft 321 passes through the primary gear 311 and is rotatably mounted on the drive seat 1. The primary gear 311 and the first connecting shaft 321 rotate synchronously and are fixed together. The second connecting shaft 322 is fixed to the drive seat 1 and passes through the secondary gear 312. Both the primary gear 311 and the secondary gear 312 are gear plates. The primary gear 311 meshes with the secondary gear 312, and the secondary gear 312 meshes with the output shaft 211. The number of gears in the primary gear 311 is greater than the number of gears in the output shaft 211. Everything else is the same as in embodiment 1. The implementation principle of this embodiment is that the secondary gear 312 makes the distribution of driving force more reasonable. Compared to the three-stage gear 313 drive in Example 1, the two-stage gear reduces axial occupancy, leaving more space for other components and reducing the overall volume of the drive seat 1, meeting the requirements for miniaturization and lightweighting of the ice maker. The two-stage gear has lower processing and assembly costs and higher transmission efficiency. When combined with the three-stage gear, a balance can be achieved between cost and performance. Example 3 differs from Example 1 in that the gear assembly 31 includes a first-stage gear 311. The connecting assembly 32 includes a first connecting shaft 321, which passes through the first-stage gear 311 and is rotatably mounted on the drive seat 1. The first-stage gear 311 rotates synchronously with the first connecting shaft 321. The first-stage gear 311 meshes with the output shaft 211, and the number of gears in the first-stage gear 311 is greater than the number of gears in the output shaft 211. This design creates a certain reduction ratio, which can increase torque output and improve the driving force of the ice maker. Everything else is the same as in Example 1. The implementation principle of this embodiment is as follows: through the cooperation of the primary gear component 311 and the output shaft 211, a certain speed reduction and torque increase effect is achieved, which can meet the basic driving force requirements of some ice makers. Moreover, the structure is relatively simple, the cost is low, and the installation and maintenance are relatively convenient, making it suitable for ice maker scenarios where the transmission requirements are not particularly complex.

[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
