Description

Technical Field

[0001] This utility model relates to the field of meat grinder technology, and in particular to a reducer for a meat grinder with stable output. Background Technology

[0002] Household meat grinders, as common kitchen appliances, typically consist of a cup-shaped container, a lid, blades, a motor, and a reducer. During operation, the motor outputs power to the reducer, which lowers the rotational speed and increases the torque, driving the blades to rotate at high speed, thus mincing the meat inside the container to meet the needs of home cooking.

[0003] However, existing household meat grinders exhibit significant problems with their reducer output during actual use. Due to limitations in the reducer's internal structure design, such as gaps between the output end of the planetary carrier and the through-hole in the bottom shell, as well as unavoidable gaps between the teeth of the planetary gears and the gear ring, and between the planetary gears and the motor output shaft, the output end of the planetary carrier is prone to wobbling during reducer operation. This not only causes unstable speed output, resulting in uneven cutting speed and affecting the meat grinding effect, making it impossible to obtain uniform and fine minced meat; it also leads to energy loss in transmission, reducing the effective utilization rate of the motor's output energy and increasing energy consumption; furthermore, this wobbling significantly increases transmission noise, causing considerable noise interference in home use and affecting the user experience.

[0004] For example, the deceleration structure disclosed in patent CN213194030U and the deceleration structure in patent CN221203937U both have the aforementioned gap problem, which causes significant shaking at the output end of the planetary carrier during operation, seriously affecting the overall performance of the meat grinder.

[0005] Therefore, it is necessary to develop a reducer for meat grinders with stable output to address the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a reducer for a meat grinder with a stable output end, which can improve the stability of the planetary carrier output end, thereby improving the stability of the speed output, reducing transmission energy loss and noise, and improving the overall performance of the meat grinder.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a reducer for a meat grinder with a stable output end, comprising a housing consisting of a detachably connected top cover and a bottom shell. A planetary carrier is rotatably mounted inside the housing, and multiple planetary gears are rotatably connected to the planetary carrier. The planetary gears mesh with the bottom shell, and the output end of the planetary carrier protrudes from the bottom shell. The device also includes:

[0009] The first positioning component is rotatably sleeved on the output end and is fixedly connected to the bottom shell.

[0010] and / or a second positioning component, which is disposed between the end of the planetary carrier away from the first positioning component and the top cover.

[0011] Optionally, the first positioning component includes a steel sleeve, and an installation hole is provided on the inner bottom wall of the bottom shell. The bottom end of the steel sleeve is fixedly connected to the installation hole, and the output end rotatably passes through the steel sleeve.

[0012] Optionally, the steel sleeve is snapped into the mounting hole, and / or a guide assembly is provided between the steel sleeve and the mounting hole.

[0013] Optionally, the bottom peripheral wall of the steel sleeve is fixed with a number of protruding snap-fit ​​parts, and the peripheral wall of the mounting hole is provided with a groove for snapping with the snap-fit ​​parts.

[0014] Optionally, a guide groove is provided on the peripheral sidewall of the mounting hole for guiding the snap-fit ​​portion, and the guide groove is provided in a one-to-one correspondence with the groove and is connected.

[0015] Optionally, the bottom peripheral wall of the mounting hole is fixed with a plurality of protruding snap-fit ​​parts, and the bottom peripheral wall of the steel sleeve is provided with a groove for snapping with the snap-fit ​​parts.

[0016] Optionally, the peripheral wall of the steel sleeve is provided with a guide groove corresponding to and communicating with the groove, and the peripheral wall of the mounting hole is fixed with a guide strip for sliding cooperation with the guide groove.

[0017] Optionally, the second positioning component includes a retaining ring fixedly connected to the top cover and a retaining groove formed at the top of the planetary carrier, wherein the retaining ring and the retaining groove are rotatably engaged.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0019] By setting a first positioning component and / or a second positioning component, the wobbling of the planetary carrier output end is effectively limited. In the first positioning component, a steel sleeve positions the output end of the planetary carrier; in the second positioning component, the rotating engagement of the retaining ring and the retaining groove provides positioning at the top of the planetary carrier; the combination of the first and second positioning components provides positioning constraint to the planetary carrier from both the top and bottom, significantly improving the stability of the output end.

Therefore, they should not be construed as limitations on this utility model.

[0036] In a specific embodiment of this utility model, such as Figures 1-10 As shown, the housing includes a detachably connected top cover 300 and a bottom shell 400. A planetary carrier 100 is rotatably mounted inside the housing. Multiple planetary gears 200 are rotatably connected to the planetary carrier 100 and mesh with the bottom shell 400. The output end 110 of the planetary carrier 100 protrudes from the bottom shell 400. The housing also includes:

[0037] The first positioning component is rotatably sleeved on the output end 110 and is fixedly connected to the bottom shell 400, and is used to position and constrain the output end 110.

[0038] And / or a second positioning component, which is disposed between the end of the planetary carrier 100 away from the first positioning component and the top cover 300, for positioning and constraining the top of the planetary carrier 100.

[0039] In a specific embodiment of this utility model, such as Figure 3As shown, the first positioning component includes a steel sleeve 500. An mounting hole is provided on the inner bottom wall of the bottom shell 400. The bottom end of the steel sleeve 500 is fixedly connected to the mounting hole, and the top end of the steel sleeve 500 is in rotatable contact with the planetary carrier 100. Auxiliary support rings 600 are respectively provided on the bottom end of the planetary carrier 100 and on the bottom shell 400. The two auxiliary support rings 600 are arranged opposite each other and rotatably in contact. The output end 110 rotatably passes through the steel sleeve 500. The steel sleeve 500 serves to position the output end 110 of the planetary carrier 100, ensuring that the output end 110 maintains a stable position and rotation trajectory during rotation. This guarantees the stability of the rotational speed output, allowing the cutter to cut the meat at a more uniform speed, improving the quality and uniformity of the minced meat. Simultaneously, the stable rotation of the output end 110 reduces collisions and friction between components, thereby reducing transmission energy loss and noise.

[0040] In a specific embodiment of this utility model, such as Figures 3-10 As shown, the steel sleeve 500 is snapped into the mounting hole and fixed, and / or a guide component is provided between the steel sleeve 500 and the mounting hole.

[0041] In a specific embodiment of this utility model, such as Figure 3 , 4 As shown in Figures 6-8, the bottom peripheral wall of the steel sleeve 500 is fixed with several protruding snap-fit ​​portions 510, and the peripheral wall of the mounting hole is provided with a groove 410 for engaging with the snap-fit ​​portions 510. The snap-fit ​​portion 510 can be a protruding spherical structure, which reduces the friction between the snap-fit ​​portion 510 and the side wall of the mounting hole when installing the steel sleeve 500, and facilitates the snap-fit ​​portion 510 entering the groove 410. The snap-fit ​​portion 510 and the groove 120 cooperate with each other to prevent the steel sleeve 500 from loosening or shifting during operation.

[0042] like Figure 3 , 4 As shown in Figures 6 and 7, the guide assembly has guide grooves 420 on the peripheral sidewall of the mounting hole for guiding the snap-fit ​​part 510. The guide grooves 420 and the recesses 410 are correspondingly arranged and connected. The guide grooves 420 cooperate with the snap-fit ​​part 510 to provide guidance for the snap-fit ​​part 510 during installation, so that the snap-fit ​​part 510 can enter the recesses 410 more accurately and conveniently.

[0043] In a specific embodiment of this utility model, such as Figure 5As shown, the second positioning component includes a retaining ring 310 fixedly connected to the top cover 300 and a retaining groove 120 formed at the top of the planetary carrier 100. The retaining ring 310 and the retaining groove 120 are rotatably engaged. During the rotation of the planetary carrier 100, the engagement of the retaining ring 310 and the retaining groove 120 constrains the top of the planetary carrier 100, limiting the swaying of the planetary carrier 100 in the vertical and horizontal directions. The second positioning component cooperates with the first positioning component at the bottom to position the planetary carrier 100 from both the top and bottom, ensuring that the planetary carrier 100 maintains a stable posture during rotation, thereby ensuring that the output end 110 stably outputs power.

[0044] In a specific embodiment of this utility model, such as Figure 9 and 10 As shown, the bottom peripheral wall of the mounting hole is fixed with several protruding snap-fit ​​parts 510, and the bottom peripheral wall of the steel sleeve 500 is provided with a groove 410 for snapping with the snap-fit ​​parts 510.

[0045] like Figure 9 and 10 As shown, the guide assembly includes a guide groove 420 on the peripheral sidewall of the steel sleeve 500, which corresponds to and communicates with the groove 410. A guide strip 430 is fixed on the peripheral sidewall of the mounting hole for sliding engagement with the guide groove 420. The guide groove 420 and the guide strip 430 cooperate to provide guidance for the steel sleeve 500 during installation, allowing the snap-fit ​​part 510 to enter the groove 410 more accurately and conveniently.

[0046] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments.
