Description

Technical Field

[0001] This utility model belongs to the field of geared motor technology, specifically relating to a geared motor and an integrated ice cream melting machine. Background Technology

[0002] Ice cream machines or slush machines typically use an integrated structure of motor and reducer to drive the internal mixer. In traditional structures, the motor is directly fixed to the end face of the reducer housing. In order to install the drive unit onto the frame of the ice cream slush machine, two symmetrical ear plates are usually set on both sides of the reducer housing. A round hole is opened in the center of the ear plate and then the ear plate is pressed onto the frame with bolts.

[0003] However, current geared motors lack dedicated protective structures and torque distribution designs. Especially when the motor starts or the load changes suddenly, the reaction torque of the entire drive unit is transmitted to the frame only through two ear plates. The stress is concentrated at the root of the ear plates, which can easily cause cracks after long-term use, leading to loose installation or even housing breakage. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a geared motor and an integrated ice cream melting machine to solve the problem that the geared motor in the prior art lacks a dedicated protective structure and torque distribution design.

[0005] One aspect of this application provides a geared motor and a geared motor, comprising: a motor housing having an internal cavity; a gear reduction module disposed inside the cavity; and a drive motor fixed to the motor housing and connected to the gear reduction module in a transmission manner, wherein the gear reduction module has a transmission structure for connecting to an external device;

[0006] The motor housing includes a first housing and a second housing. The side of the first housing is provided with an outwardly protruding protective cover. The drive motor is housed and installed inside the protective cover, and part of the drive motor is wrapped by the protective cover.

[0007] The second housing has several integrally formed mounting parts on both sides. Each mounting part includes a mounting portion and a first mounting hole. The mounting portion is an arc-shaped structure that extends outward from the second housing and gradually narrows. The first mounting hole is located at the end of the mounting portion. The second housing is mounted on the frame by fasteners that pass through the first mounting hole. The mounting parts are used to distribute the reaction torque of the drive motor during operation.

[0008] Furthermore, this application also proposes that one side of the second housing has at least two of the aforementioned mounting members, and one side of the mounting member is provided with a weight-reducing hole or a weight-reducing groove for reducing the weight of the second housing.

[0009] Furthermore, this application also proposes that the second housing has a plurality of second mounting holes on the side opposite to the first housing, the second mounting holes being located on both sides of the second housing, and fasteners being provided inside the second mounting holes for fixing the first housing and the second housing together.

[0010] Furthermore, this application also proposes to include a fixing seat disposed between the motor housing and the frame, the fixing seat being mounted on the frame;

[0011] The mounting base is provided with a positioning groove, the shape of which corresponds to the outer contour of the second housing, and the second housing is positioned and installed on the mounting base.

[0012] Furthermore, this application also proposes that a wiring hole is provided on one side of the protective cover, and the connection port of the drive motor corresponds to the wiring hole, for connecting the power supply and control cables to the drive motor through the connection port.

[0013] Furthermore, this application also proposes that the deceleration module includes an input gear, an intermediate gear, and an output gear. The input gear and the intermediate gear are mounted between the inner walls of the first housing and the second housing via a rotating shaft, and the output gear is mounted between the inner walls of the first housing and the second housing via a bearing.

[0014] Furthermore, this application also proposes that a connecting member is provided at the center of the output gear, and the connecting member has an axially arranged transmission connection hole.

[0015] Furthermore, this application also proposes that a first partition is provided on the inner side of the first housing, the first partition forming a first cavity, the input gear and the intermediate gear being partially housed in the first cavity, and the output gear being completely housed within the first cavity;

[0016] And / or, a second partition is provided on the inner side of the second housing, the second partition forming a second cavity, in which the input gear and the intermediate gear are partially housed.

[0017] Furthermore, this application also proposes that a first reinforcing rib be provided between the outer side of the first partition and the inner wall of the first housing;

[0018] A second reinforcing rib is provided between the outer side of the second partition and the inner wall of the second housing.

[0019] Furthermore, this application also proposes an ice cream melting machine, including a geared motor as described in any of the above embodiments, wherein the mounting component of the geared motor is fixed to the frame of the ice cream melting machine by fasteners, and further includes a connecting rod rotatably mounted on the motor housing and connected to the gear reduction module for transmission. The connecting rod is driven by the drive motor through the gear reduction module, and the end of the connecting rod is connected to the rotating shaft of the stirrer.

[0020] As can be seen from the above, this application increases the installation area by housing the drive motor in the protective cover on the side of the first housing and using multiple arc-shaped integrally formed mounting parts, which effectively disperses the reaction torque during motor operation and solves the problem of stress concentration in the traditional ear plate structure. At the same time, the overall structural rigidity is enhanced by the internal partition and reinforcing ribs of the housing, and the weight is reduced by the weight-reducing holes set in the mounting parts, thereby improving the installation stability, durability and assembly efficiency of the geared motor in the ice cream melting machine.

[0035] 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.

[0036] Please refer to Figures 1-4 One aspect of this application provides a geared motor and a geared motor, comprising: a motor housing 1 having an internal cavity; a gear reduction module 2 disposed inside the cavity; and a drive motor 3 fixed to the motor housing 1 and connected to the gear reduction module 2 in a transmission manner, wherein the gear reduction module 2 has a transmission structure for connecting to an external device.

[0037] The motor housing 1 includes a first housing 11 and a second housing 12. The side of the first housing 11 is provided with an outwardly protruding protective cover 4. The drive motor 3 is housed and installed in the protective cover 4, and part of the drive motor 3 is wrapped by the protective cover 4.

[0038] The second housing 12 has several integrally formed mounting parts 5 on both sides. Each mounting part 5 includes a mounting portion 51 and a first mounting hole 52. The mounting portion 51 is an arc-shaped structure that extends outward from the second housing 12 and gradually narrows. The first mounting hole 52 is connected to the end of the mounting portion 51. The second housing 12 is mounted on the frame by fasteners that pass through the first mounting hole 52. The mounting parts 5 are used to distribute the reaction torque of the drive motor 3 during operation.

[0039] The design employs a split housing structure consisting of a first housing 11 and a second housing 12. The drive motor 3 is integrated into the protective cover 4 of the first housing 11. The arc-shaped mounting pieces 5 on both sides of the second housing 12 are used to distribute torque. The reduction module 2 is built into the housing cavity and forms a transmission connection with the drive motor 3. During operation, the high-speed rotation of the output shaft of the drive motor 3 is converted into a low-speed, high-torque output by the reduction module 2. The integrated arc-shaped design of the mounting pieces 5, through geometric optimization, distributes the reaction torque of the drive motor 3 from several integrally formed mounting pieces 5 on both sides of the second housing 12 to a larger installation area. Finally, the load is evenly distributed to the frame through fasteners, avoiding stress concentration.

[0040] Specifically, this application improves dust and water resistance by wrapping the drive motor 3 with a protective cover 4. At the same time, the design of the arc-shaped mounting part 5 achieves a larger installation area, effectively dispersing the reaction torque during start-up, shutdown or sudden load changes, significantly reducing the risk of stress concentration at the connection and extending the life of the housing. The split housing and modular design facilitate maintenance and assembly, and the overall design takes into account stability, durability and ease of installation.

[0041] This application further proposes that one side of the second housing 12 has at least two of the aforementioned mounting members 5, and one side of the mounting portion 51 is provided with weight-reducing holes or weight-reducing grooves. The weight-reducing holes or grooves reduce the overall mass of the second housing 12 by utilizing the principle of material removal. The distribution of the weight-reducing holes / grooves is typically based on topology optimization design, that is, removing redundant material in non-critical load-bearing areas while retaining the main force transmission path of the structure, ensuring that the torsional stiffness and strength of the curved components are not significantly affected. The weight-reducing holes or grooves significantly reduce the weight of the second housing 12, alleviating the load on the frame. Simultaneously, the reduction in material saves costs, and by locally reducing weight, the inertial load on the housing during motor start-up / stop or sudden load changes is indirectly distributed.

[0042] Please refer to Figure 5 This application further proposes that the second housing 12 is provided with a plurality of second mounting holes 13 on the side opposite to the first housing 11. The second mounting holes 13 are located on both sides of the second housing 12, and fasteners are provided inside the second mounting holes 13 for fixing the first housing 11 and the second housing 12 together.

[0043] Specifically, by providing a plurality of second mounting holes 13 on the side of the second housing 12 away from the first housing 11, and the second mounting holes 13 being symmetrically distributed on both sides and the top of the second housing 12, and by using fasteners (such as bolts) to pass through the two housings to achieve mechanical connection, the first housing 11 and the second housing 12 are pressed together by a uniformly distributed fastening force, ensuring the coaxiality and structural stability of the reduction module 2 and the drive motor 3 within the housing. This embodiment effectively disperses the stress on the housing joint surface, and at the same time facilitates disassembly and maintenance or replacement of internal components.

[0044] Please refer to Figure 6 This application further proposes that it also includes a fixing seat 6 disposed between the motor housing 1 and the frame, the fixing seat 6 being mounted on the frame;

[0045] The fixing base 6 is provided with a positioning groove, the shape of which corresponds to the outer contour of the second housing 12, and the second housing 12 is positioned and installed on the fixing base 6.

[0046] Specifically, by setting a fixed seat 6 with a positioning groove on the frame, precise positioning is achieved by using the geometric matching of the positioning groove with the outer contour of the second housing 12; wherein the fixed seat 6 serves as an intermediate connecting part 24, and the contour of its positioning groove perfectly matches the shape of the mounting surface of the second housing 12 (such as an arc or a polygon). During installation, the second housing 12 is simply inserted into the positioning groove, which automatically completes the initial radial and axial alignment, and then fixed by fasteners, forming a dual fixing mechanism of "positioning groove guidance + bolt locking".

[0047] Furthermore, the tight fit between the mounting base 6 and the housing can disperse the vibration load during motor operation, reducing the risk of bolt loosening. At the same time, the modular design facilitates the pre-installation of the mounting base 6 and the frame, making it suitable for mass production scenarios.

[0048] This application further proposes that a wiring hole 41 is provided on one side of the protective cover 4, and the connection port of the drive motor 3 corresponds to the wiring hole 41, for connecting the power supply and control cables to the drive motor 3 through the connection port.

[0049] Specifically, by setting a wiring hole 41 on one side of the protective cover 4, it is precisely aligned with the connection port of the drive motor 3, so that the power supply and control cables can be inserted and connected; at the same time, the wiring hole 41 adopts a sealed structure (such as a rubber ring or a waterproof groove) to ensure that the dustproof and waterproof performance of the protective cover 4 can still be maintained when the cable passes through.

[0050] Specifically, the cables are led out through dedicated holes, reducing the risk of cable damage caused by external friction or bending. On the other hand, the sealing structure (such as a waterproof groove or rubber ring) effectively prevents moisture and dust from entering the protective cover 4, ensuring the stable operation of the motor in harsh environments. In addition, the standardized wiring hole 41 position facilitates assembly consistency during mass production, and simplifies cable inspection and replacement operations during later maintenance, eliminating the need to check and confirm the cable wiring position.

[0051] Please refer to Figure 3 This application further proposes that the deceleration module 2 includes an input gear 21, an intermediate gear 22 and an output gear 23. The input gear 21 and the intermediate gear 22 are mounted between the inner walls of the first housing 11 and the second housing 12 via a rotating shaft, and the output gear 23 is mounted between the inner walls of the first housing 11 and the second housing 12 via a bearing.

[0052] Wherein, the input gear 21 and the intermediate gear 22 are both two-stage cylindrical gears. The input gear 21 is meshed with the output end of the drive motor 3, the intermediate gear 22 is meshed with the input gear 21, and the output gear 23 is meshed with the intermediate gear 22.

[0053] Specifically, the three-stage gear transmission achieves speed reduction and torque increase: the input gear 21 receives the high-speed rotational power of the drive motor 3, driving the intermediate gear 22 to perform the first stage of speed reduction; the intermediate gear 22 is fixed to the housing through a rotating shaft, transmitting power to the output gear 23 to complete the second stage of speed reduction; the output gear 23 is supported on the inner wall of the housing by bearings, and finally outputs low speed and high torque to external devices; in this embodiment, the gear set of the speed reduction module 2 adopts a hybrid fixing method of rotating shaft and bearing, which ensures the axial positioning accuracy of the gears (rigid support of the rotating shaft) and reduces the friction loss at the output end through the bearings, thereby achieving efficient power transmission.

[0054] Please refer to Figure 3 This application further proposes that a connecting member 24 is provided at the center of the output gear 23, and the connecting member 24 has an axially arranged transmission connection hole 25.

[0055] In this embodiment, a connector 24 with an axial transmission connection hole 25 is provided at the center of the output gear 23. Power transmission is achieved by using the hole-shaft fit. The transmission connection hole 25 is usually designed as a keyway, spline or thread structure, which can be directly inserted into the external transmission shaft or locked by fasteners (such as bolts) to form a rigid connection. This allows the rotational motion of the output gear 23 to be directly converted into the torque of the output shaft through the connection hole, and ensures transmission stability.

[0056] Please refer to Figures 4-5This application further proposes that a first partition 14 is provided on the inner side of the first housing 11, the first partition 14 forming a first cavity, the input gear 21 and the intermediate gear 22 are partially housed in the first cavity, and the output gear 23 is completely housed in the first cavity.

[0057] And / or, a second partition 15 is provided on the inner side of the second housing 12, the second partition 15 forming a second cavity, in which the input gear 21 and the intermediate gear 22 are partially housed.

[0058] Meanwhile, the first and second cavities simultaneously form a semi-enclosed protection for multiple gears of the reduction module 2, preventing grease from being thrown out and enabling pre-positioning of multiple gears during assembly.

[0059] This application further proposes that a first reinforcing rib is provided between the outer side of the first partition 14 and the inner wall of the first housing 11;

[0060] A second reinforcing rib is provided between the outer side of the second partition 15 and the inner wall of the second housing 12.

[0061] This embodiment enhances the connection rigidity between the shell and the partition by setting a first and a second reinforcing rib between the partition and the inner wall of the shell, utilizing a ribbed structure. The reinforcing ribs typically adopt a radial or grid-like layout, with their roots integrally formed with the partition and the inner wall of the shell to create a supporting structure. When the drive motor 3 generates vibration or impact loads, the reinforcing ribs disperse the stress path, transforming the localized concentrated load into a multi-directional distributed force, thereby suppressing shell deformation and achieving structural strengthening of the shell while reducing its weight.

[0062] This application further proposes an ice cream melting machine, including a geared motor as described in any of the above embodiments. The mounting part 5 of the geared motor is fixed to the frame of the ice cream melting machine by fasteners. It also includes a connecting rod, which is rotatably mounted on the motor housing 1 and is connected to the gear reduction module 2 for transmission. The connecting rod is driven by the drive motor 3 through the gear reduction module 2. The end of the connecting rod is connected to the rotating shaft of the stirrer.

[0063] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
