Description

Technical Field

[0001] This utility model relates to the field of meat grinder technology, and in particular to a transmission reduction device for a meat grinder. Background Technology

[0002] Most meat grinders on the market today use a motor to increase torque through a gearbox, which in turn drives a grinding screw to grind meat. However, the gearboxes of traditional meat grinders typically use multiple stages of gear meshing to achieve multi-stage gear transmission, gradually increasing the gear ratio to achieve speed reduction. This results in a large number of gear stages, taking up considerable space, and the power transmission is done one gear at a time, with each individual gear having relatively low strength, making the gearbox prone to failure. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a transmission reduction device for a meat grinder to solve the above-mentioned problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a transmission reduction device for a meat grinder, including a motor, a primary transmission module, a secondary transmission module, an inner gear cover and a bushing;

[0005] The primary transmission module includes a primary driving gear and a primary driven gear set. The primary driving gear is fixedly connected to the output shaft of the motor, and the primary driving gear is drivenly connected to the primary driven gear set.

[0006] The secondary transmission module includes a secondary driving gear set and a secondary driven gear. The secondary driven gear is fixedly connected to the bushing, and the secondary driving gear set is drivingly connected to the secondary driven gear. The shaft of the primary driving gear and the shaft of the secondary driven gear are in a non-contact state.

[0007] Both the primary transmission module and the secondary transmission module are located inside the internal gear cover, and both the primary driven gear set and the secondary driving gear set mesh with the internal teeth inside the internal gear cover.

[0008] It is worth noting that the primary driven gear set includes multiple primary driven gears, which are arranged around the primary driving gear, and all the primary driven gears mesh with the internal teeth of the internal gear cover.

[0009] Preferably, the secondary driving gear set includes multiple secondary driving gears, all of which are arranged around the secondary driven gear, and all of which mesh with the internal teeth of the internal gear cover.

[0010] Optionally, the primary transmission module further includes a primary upper cover and a primary lower cover, wherein the primary driving gear and the primary driven gear set are both disposed between the primary upper cover and the primary lower cover, wherein the primary driving gear is located at the center of the primary lower cover.

[0011] Specifically, the secondary transmission module further includes a secondary upper cover and a secondary lower cover, and the secondary driving gear and the secondary driven gear are both disposed between the secondary upper cover and the secondary lower cover, wherein the secondary driven gear is located at the center of the secondary lower cover.

[0012] It is worth noting that the lower surface of the primary upper cover is provided with a first support rod, which extends toward the primary lower cover, and the length of the first support rod is greater than the thickness of both the primary driving gear and the primary driven gear.

[0013] Specifically, the lower surface of the secondary upper cover is provided with a second support rod, which extends toward the secondary lower cover, and the length of the second support rod is greater than the thickness of both the secondary driving gear and the secondary driven gear.

[0014] The beneficial effects of this utility model are as follows: In the transmission reduction device of the meat grinder, the motor drives the primary driving gear to rotate, which in turn drives the gears in the primary driven gear set to rotate. This, in turn, drives the inner gear cover to rotate through the meshing structure. After the inner gear cover rotates, it drives the gears in the secondary driving gear set to rotate through the meshing structure, which in turn drives the secondary driven gear to rotate. Finally, the secondary driven gear drives the bushing to rotate, and the bushing is used to drive the meat grinder screw to rotate. In the primary transmission module, the primary driving gear and the primary driven gear set can be arranged on the same plane. In the secondary transmission module, the secondary driving gear set and the secondary driven gear can be arranged on the same plane. The transmission between the primary and secondary transmission modules is achieved through the inner gear cover, thus saving space. During the transmission process, all gears in the primary driven gear set simultaneously drive the inner gear cover to rotate, and all gears in the secondary driving gear set simultaneously drive the secondary driven gear to rotate. This improves the force distribution during transmission, increases strength, and reduces the probability of failure. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1-5 As shown, a transmission reduction device for a meat grinder includes a motor 1, a primary transmission module 2, a secondary transmission module 3, an internal gear cover 4, and a bushing 5.

[0023] like Figure 1 and 3 As shown, the primary transmission module 2 includes a primary driving gear 21 and a primary driven gear set. The primary driving gear 21 is fixedly connected to the output shaft of the motor 1, and the primary driving gear 21 is connected to the primary driven gear set in a transmission connection.

[0024] like Figure 1 and 4 As shown, the secondary transmission module 3 includes a secondary driving gear set and a secondary driven gear 31. The secondary driven gear 31 is fixedly connected to the bushing 5, and the secondary driving gear set is drivingly connected to the secondary driven gear 31. The shaft of the primary driving gear 21 and the shaft of the secondary driven gear 31 are in a non-contact state, thereby avoiding mutual interference between the shafts of the primary driving gear 21 and the secondary driven gear 31.

[0025] like Figure 1 and 2 As shown, the primary transmission module 2 and the secondary transmission module 3 are both disposed inside the internal gear cover 4, and the primary driven gear set and the secondary driving gear set are both meshed with the internal teeth inside the internal gear cover 4.

[0026] In the transmission and reduction device of the meat grinder, the motor 1 drives the primary drive gear 21 to rotate, which in turn drives the gear in the primary driven gear set to rotate. This, in turn, drives the inner gear cover 4 to rotate through the meshing structure. After the inner gear cover 4 rotates, it drives the gear in the secondary drive gear set to rotate through the meshing structure. This then drives the secondary driven gear 31 to rotate, and finally drives the bushing 5 to rotate through the secondary driven gear 31. The bushing 5 is used to drive the meat grinder screw to rotate. In the primary transmission module 2, the primary driving gear 21 and the primary driven gear set can be arranged on the same plane. In the secondary transmission module 3, the secondary driving gear set and the secondary driven gear 31 can be arranged on the same plane. The transmission between the primary transmission module 2 and the secondary transmission module 3 is achieved through the internal gear cover 4, thereby saving space. During the transmission process, all gears in the primary driven gear set drive the internal gear cover 4 to rotate simultaneously, and all gears in the secondary driving gear set drive the secondary driven gear 31 to rotate simultaneously. This improves the force during the transmission process, increases the strength, and reduces the probability of failure.

[0027] Preferred, such as Figure 2 , 3 As shown in Figure 5, the primary driven gear set includes multiple primary driven gears 22, all of which are arranged around the primary driving gear 21, and all of which mesh with the internal teeth of the internal gear cover 4. In this embodiment, the primary driven gears 22 are evenly distributed along the outer circumference of the primary driving gear 21, and all mesh with the external teeth of the primary driving gear 21, thereby ensuring that the primary driving gear 21 and the primary driven gears 22 are both subjected to force balance.

[0028] Optional, such as Figure 2 , 4 As shown in Figure 5, the secondary driving gear set includes multiple secondary driving gears 32. All the secondary driving gears 32 are arranged around the secondary driven gear 31, and all the secondary driving gears 32 mesh with the internal teeth of the internal gear cover 4. In this embodiment, the secondary driving gears 32 are evenly distributed along the outer circumference of the secondary driven gear 31, and all mesh with the external teeth of the secondary driven gear 31, thereby ensuring that both the secondary driven gear 31 and the secondary driving gear 32 are subjected to force balance.

[0029] Specifically, such as Figure 1 and 3As shown, the primary transmission module 2 further includes a primary upper cover 23 and a primary lower cover 24. The primary driving gear 21 and the primary driven gear set are both disposed between the primary upper cover 23 and the primary lower cover 24, wherein the primary driving gear 21 is located at the center of the primary lower cover 24. The primary driving gear 21 and the primary driven gear 22 are both disposed between the primary upper cover 23 and the primary lower cover 24 via corresponding rotating shafts. The primary upper cover 23 and the primary lower cover 24 cooperate to fix the rotating shafts, thereby preventing the primary driving gear 21 and the primary driven gear 22 from misaligning or shifting.

[0030] It is worth noting that, such as Figure 1 and 4 As shown, the secondary transmission module 3 further includes a secondary upper cover 33 and a secondary lower cover 34. The secondary driving gear 32 and the secondary driven gear 31 are both disposed between the secondary upper cover 33 and the secondary lower cover 34, with the secondary driven gear 31 located at the center of the secondary lower cover 34. The secondary driven gear 31 and the secondary driving gear 32 are both disposed between the secondary upper cover 33 and the secondary lower cover 34 via corresponding rotating shafts. The secondary upper cover 33 and the secondary lower cover 34 cooperate to fix the rotating shafts, thereby preventing misalignment or displacement of the secondary driven gear 31 and the secondary driving gear 32.

[0031] Preferred, such as Figure 1 As shown, a first support rod 25 is provided on the lower surface of the primary upper cover 23. The first support rod 25 extends towards the primary lower cover 24, and the length of the first support rod 25 is greater than the thickness of both the primary driving gear 21 and the primary driven gear 22. By providing the first support rod 25, sufficient height between the primary upper cover 23 and the primary lower cover 24 can be ensured to accommodate the primary driving gear 21 and the primary driven gear 22, ensuring that the primary driving gear 21 and the primary driven gear 22 can rotate stably between the primary upper cover 23 and the primary lower cover 24.

[0032] Optional, such as Figure 1 and 4 As shown, the lower surface of the secondary upper cover 33 is provided with a second support rod 35. The second support rod 35 extends towards the secondary lower cover 34, and the length of the second support rod 35 is greater than the thickness of both the secondary driving gear 32 and the secondary driven gear 31. By providing the second support rod 35, sufficient height between the secondary upper cover 33 and the secondary lower cover 34 can be ensured to accommodate the secondary driving gear 32 and the secondary driven gear 31, ensuring that the secondary driving gear 32 and the secondary driven gear 31 can rotate stably between the secondary upper cover 33 and the secondary lower cover 34.
