Description

Technical Field

[0001] The utility model relates to the technical field of planetary transmissions, in particular to a planetary transmission pair of a transmission. Background Art

[0002] Planetary transmission is a common type of transmission, which achieves speed change through a planetary gear mechanism. The planetary gear mechanism consists of a sun gear, a planetary gear and a ring gear. According to the different movements of these three components, different combinations can be achieved, including the input shaft and the output shaft being out of the rigid transmission relationship, the input shaft and the output shaft being driven in the same or opposite direction, and the input and output shaft transmission ratio changing. It is widely used in land, sea, aviation and other transportation vehicles.

[0003] According to the search, the Chinese patent document, announcement number: CN205592371U, discloses a planetary gear continuously variable transmission, which greatly reduces the material consumption by setting the original disc-shaped planetary frame to three connecting plates evenly distributed, saves costs under the same strength and hardness, and uses permanent magnets to absorb fine debris to extend the service life of the planetary gears. However, in the actual use of the device, the permanent magnet will not only absorb some magnetic impurities, such as iron filings, rust, etc., which will cause the gears to malfunction when working after excessive accumulation, but also the permanent magnet will produce a magnetization effect on the gears, which will affect the overall working performance and life of the device; in addition, the device is only equipped with one set of planetary gears, so it cannot provide a wider range of transmission ratio selection, which reduces the overall practicality of the device. Utility Model Content

[0008] Preferably, the number of the support seats and the number of the gear rings are both three, and the number of the stabilizing rods is plural.

[0009] Through the above technical solution, the three support seats can provide effective support for the three gear rings, and the multiple stabilizing rods can fix the positions of the three gear rings and keep them firm, thereby enhancing the overall stability of the device.

[0010] Preferably, the number of the vertical plate, the first bearing, the sun gear and the bearing seat is three, and the three bearing seats are respectively installed inside the three first bearings.

[0011] Through the above technical solution, the three vertical plates can effectively limit the positions of the three sun gears, and the three bearing seats can also rotate inside the three first bearings respectively. Therefore, when the leftmost bearing seat is connected to an external driving device, it can drive the entire device to move, thereby improving the overall stability and practicality of the device.

[0012] Preferably, the number of the planetary gears and the number of the second bearings are both nine, and the nine planetary gears are evenly distributed inside the three gear rings.

[0013] Through the above technical solution, when the driving device drives the leftmost bearing seat and the sun gear to rotate, the sun gear can drive the three planetary gears to rotate inside the gear ring. The three planetary gears can not only rotate on the outside of the three second bearings, but also revolve around the outer side of the sun gear. Similarly, the other six planetary gears can also rotate and revolve under the drive of parts such as the connecting bracket. Therefore, by setting three sets of planetary gears, a wider range of transmission ratio selection can be effectively provided, thereby improving the overall practicality of the device.

Therefore, with the cooperation of the rotating shaft and other parts, the other six connecting rods and other parts can be driven to rotate, thereby improving the overall practicality of the device.

[0016] Preferably, there are three rotating shafts, and two of the rotating shafts are correspondingly installed inside two of the bearing seats.

[0017] Through the above technical solution, when the leftmost connecting bracket and the rotating shaft rotate, the rotating shaft can drive one of the bearing seats and one of the sun gears to rotate, and the sun gear can then engage with the other three planetary gears to rotate and revolve. Similarly, another set of sun gears can also indirectly drive the connecting bracket and the rotating shaft to rotate. Therefore, it can effectively provide a wider range of transmission ratio selection, thereby improving the overall practicality of the device.

[0028] Specifically, the number of the support seats 3 and the number of the gear rings 5 ​​are both three, and the number of the stabilizing rods 14 is multiple. The advantage is that through this structure, the three support seats 3 can provide effective support for the three gear rings 5, and the multiple stabilizing rods 14 can fix the positions of the three gear rings 5 ​​and keep them firm, thereby enhancing the overall stability of the device.

[0029] Specifically, there are three vertical plates 2, three first bearings 4, three sun gears 7 and three bearing seats 13, and the three bearing seats 13 are respectively installed inside the three first bearings 4. The advantage is that the three vertical plates 2 can effectively limit the positions of the three sun gears 7 through this structure, and the three bearing seats 13 can also rotate inside the three first bearings 4 respectively, so when the leftmost bearing seat 13 is connected to an external driving device, it can drive the entire device to move, thereby improving the overall stability and practicality of the device.

[0030] Specifically, the number of the planetary gears 6 and the number of the second bearings 8 are both nine, and the nine planetary gears 6 are evenly distributed inside the three gear rings 5. The advantage is that, through this structure, when the driving device drives the leftmost bearing seat 13 and the sun gear 7 to rotate, the sun gear 7 can drive the three planetary gears 6 to rotate inside the gear ring 5, and the three planetary gears 6 can not only rotate on the outside of the three second bearings 8, but also revolve around the outer side of the sun gear 7. Similarly, the other six planetary gears 6 can also rotate and revolve under the drive of the connecting bracket 11 and other parts. Therefore, by setting three sets of planetary gears 6, a wider range of transmission ratio selection can be effectively provided, thereby improving the overall practicality of the device.

[0031] Specifically, the number of connecting rods 9 and third bearings 10 is nine, the number of connecting brackets 11 is three, and the nine third bearings 10 are evenly distributed inside the three connecting brackets 11.

At the same time, the three connecting rods 9 can rotate inside the three third bearings 10 and drive the connecting bracket 11 and the rotating shaft 12 to rotate. This rotating shaft 12 can drive another bearing seat 13 and another sun gear 7 to rotate. Similarly, this sun gear 7 can also indirectly drive this group of connecting brackets 11 and rotating shaft 12 to rotate. Therefore, by setting three groups of planetary gears 6 and sun gears 7 and other parts, a wider range of transmission ratio selection can be effectively provided, thereby improving the overall practicality of the device; at the same time, the three support seats 3 can provide effective support for the three gear rings 5, and multiple stabilizing bars 14 can fix the positions of the three gear rings 5 ​​and keep them firm. The three vertical plates 2 can effectively limit the positions of the three sun gears 7, thereby enhancing the overall stability of the device.
