[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0039] See Figure 1 and Figure 2 This utility model discloses an embedded ice cream and smoothie all-in-one machine. The embedded ice cream and smoothie all-in-one machine uses a speed reduction device, which enables the embedded ice cream and smoothie all-in-one machine to make ice cream and smoothie. When the embedded ice cream and smoothie all-in-one machine is working, the power output is stable, which meets the high torque required when making ice cream and the high speed required when making smoothie.
[0040] The speed reduction device will be described in detail below with reference to the accompanying drawings.
[0041] A speed reduction device includes a power input shaft 1, a power output shaft 2, and a power transmission mechanism 3, wherein the power transmission mechanism 3 drivesly connects the power input shaft 1 and the power output shaft 2.
[0042] The power transmission mechanism 3 includes a transmission reversing mechanism 31 and a reduction mechanism 32 that are connected in a transmission manner. The power reversing mechanism is connected in a transmission manner to the power input shaft 1, and the reduction mechanism 32 directly drives the power output shaft 2 to rotate. The axes of the power input shaft 1 and the power output shaft 2 are perpendicular.
[0043] In the above scheme, the transmission of the power input shaft is reversed by using the transmission reversing mechanism 31, so that the power output shaft is perpendicular to the power input shaft, thereby reducing the volume of the reduction device and making the reduction device structure compact.
[0044] In the above scheme, by adopting the transmission reversing mechanism 31, the first stage of deceleration is also realized, which reduces the motion input by the power input shaft and increases the speed output selection of this deceleration device.
[0045] In the above scheme, by adding a reduction mechanism 32 at the rear of the transmission reversing mechanism 31, two-stage reduction is achieved, further reducing the output speed of the power output shaft, so that the reduction device meets the usage requirements.
[0046] In the above solution, by adopting the transmission reversing mechanism 31 and the reduction mechanism 32, the reduction requirements of the reduction device can be met, the structure of the reduction device can be simplified, and the reduction device can be miniaturized, lightweight and compacted.
[0047] In this technical solution, the transmission reversing mechanism 31 includes a helical gear 312 and a worm gear 311 that mesh with each other. The worm gear 311 is connected to the power input shaft 1, and the helical gear 312 is connected to the reduction mechanism 32.
[0048] In the above scheme, the meshing of helical gears and worm gears achieves reversal and speed reduction of the power input shaft transmission. The structure is simple and multifunctional. Here, helical gear 312 is selected for meshing with the worm gear 311. In transmission, this improves transmission efficiency, reduces noise, ensures smooth operation, and provides a large transmission ratio, high output torque, high load-bearing capacity, and long service life.
[0049] In common mechanical transmission structures, the worm gear typically meshes with the worm. However, due to the structure of the worm, in some structures or situations, a helical gear can be used instead of the worm gear to mesh with the worm and achieve power transmission. When designing the meshing of the worm and helical gear, the normal module and normal pressure angle of the helical gear, as well as the axial module and tooth profile of the worm, should be considered to ensure that they can mesh correctly and transmit the required torque. Of course, in existing technologies, the meshing of helical gears and worms is also a common mechanical transmission structure. Here, we can use the existing worm and helical gear transmission structure that meets the requirements of this technical solution without making any creative changes to the structure of the worm and helical gear themselves.
[0050] In the above scheme, the use of helical gear and worm gear transmission has advantages over worm wheel and worm gear transmission, such as high transmission efficiency, low transmission capacity loss, large transmission torque, and high load-bearing capacity of the transmission structure.
[0051] In this technical solution, to simplify the installation of the worm gear, the worm gear 311 is fixedly connected to the power input shaft 1. Specifically, the power input shaft is coaxially and fixedly connected to the worm gear, and the power input shaft directly drives the worm gear to rotate. The structure is simple and compact, with low manufacturing and maintenance costs and small size.
[0052] In this technical solution, to further simplify the connection between the worm and the power input shaft, the worm 311 is integrally formed with the power input shaft 1, that is, the teeth of the worm are directly formed on the power input shaft, and after installation, it is ensured that the teeth of the worm mesh with the helical gear, thereby improving the strength of the power input shaft and the worm and increasing the output torque of the worm.
[0053] In this technical solution, the reduction mechanism 32 includes a planetary gear mechanism. The planetary gear mechanism includes a sun gear 321, a planetary gear 322 meshing with the sun gear 321, a fixed internal gear ring meshing with the planetary gear 322, and a planet carrier 323 driven by the planetary gear 322. The planet carrier 323 is connected to the power output shaft 2, and the sun gear 321 is driven by the helical gear 312.
[0054] In the above scheme, when the planetary gear mechanism is working, the helical gear 312 drives the sun gear to rotate, the sun gear meshes with the planet gear, and drives the planet gear to rotate on its own. At the same time, the planet gear meshes with the fixed internal gear ring, and the planet gear revolves around the sun gear synchronously, thereby driving the planet carrier to rotate, and the planet carrier drives the power output shaft to rotate.
[0055] In the above solution, a planetary gear mechanism is used to achieve further speed reduction. The planetary carrier 323 is connected to the power output shaft 2 to improve the torque resistance of the power output shaft and ensure that the power output shaft can withstand high output torque to meet the requirements and needs of ice cream production.
[0056] In the above scheme, a planetary gear mechanism is used as the reduction mechanism, which has a compact structure, high transmission efficiency, high load-bearing capacity, large transmission ratio, and smooth operation. During transmission, the planetary gear mechanism can evenly distribute the load to each planetary gear, resulting in a smaller load on each planetary gear and thus improving the overall load-bearing capacity of the mechanism. Therefore, in the above scheme, the planetary carrier 323 is connected to the power output shaft 2, and the planetary carrier is driven by the planetary gears, reducing the requirements on the planetary gears.
[0057] In this technical solution, the sun gear 321 and the helical gear 312 are coaxially fixed, and the power output shaft 2 is coaxially arranged with the sun gear 321. Installation is simple, the motion output is smooth, noise is minimal, and vibration is low.
[0058] In this technical solution, the sun gear 321 and the helical gear 312 are integrally formed, which avoids the error of coaxial installation of the sun gear and the helical gear, reduces the installation difficulty, and reduces the number of parts.
[0059] In this technical solution, the deceleration device further includes an outer shell 5. The outer shell 5 includes a first shell 51 and a second shell 52 disposed opposite to each other. A middle partition 53 is provided between the first shell 51 and the second shell 52. The first shell 51 and the second shell 52 are detachably and fixedly connected to the middle partition 53. The middle partition 53 forms a first cavity and a second cavity with the first shell 51 and the second shell 52, respectively. The transmission reversing mechanism 31 and the deceleration mechanism 32 are respectively disposed in the first cavity and the second cavity. The power output shaft 2 passes through the second shell 52 and extends out.
[0060] By providing a first housing and a second housing, the transmission reversing mechanism 31 and the reduction mechanism 32 are respectively installed. The first housing and the second housing, together with the intermediate partition, form a first cavity and a second cavity, respectively, which are adapted to the volume and structure of the transmission reversing mechanism 31 and the reduction mechanism 32, reducing the volume of the reduction device and achieving a lightweight and miniaturized reduction mechanism. Furthermore, the separate provision of the first housing and the second housing for installing the transmission reversing mechanism 31 and the reduction mechanism 32 facilitates their installation, repair, and maintenance.
[0061] In this technical solution, at least two planetary gears 322 are provided and evenly distributed around the outer periphery of the sun gear 321. The power output shaft 2 is coaxially fixed to the planet carrier 323. This improves the torque resistance of the planet carrier, reduces the force on each planetary gear, and ensures uniform force distribution on the sun gear. The planetary gears are connected to the planet carrier via connecting posts 324, rotating on their own axes and revolving around the planet carrier.
[0062] An embedded ice cream and smoothie machine includes a drive motor 4 and the aforementioned reduction gear, wherein the motor shaft of the motor 4 is fixedly connected to the power input shaft 1.
[0063] The embedded ice cream and smoothie maker in this design utilizes the aforementioned reduction gear, enabling it to achieve high output torque and low output speed, thus meeting the requirements for ice cream production. The motor shaft is fixedly connected to the power input shaft, simplifying the structure, improving the torque resistance of both the power output and input shafts, and extending the service life of the embedded ice cream and smoothie maker.
[0064] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
