Description

Technical Field

[0001] The utility model relates to the technical field of planetary gear mechanisms, in particular to an integrated planetary gear which is easy to assemble and disassemble. Background Art

[0002] A planetary gear set is a mechanical transmission device that mainly consists of a sun gear, planet gears, and a ring gear. The sun gear is located at the center and is usually the key component for power input or output. The planet gears rotate around the sun gear. Generally, there are multiple planet gears evenly distributed around the sun gear and connected together by a planet carrier. The ring gear surrounds the outside of the planet gears. Planetary gear sets have the following characteristics and advantages:

[0003] High transmission ratio: A wide range of transmission ratio changes can be achieved through different combinations to meet different speed and torque requirements;

[0004] Compact structure: realizes complex transmission functions in a relatively small space, suitable for occasions with limited space;

[0005] Strong load-bearing capacity: Multiple planetary gears share the load, allowing the entire system to withstand greater torque and force.

[0006] Currently, existing planetary gear sets (such as Publication No. CN210423598U) disclose a planetary gear assembly, which uses a driving shaft to drive the sun gear to rotate, and the sun gear to drive the planetary gears to rotate. The planetary gears rotate on the surface of the rotating shaft, and the driving shaft and the rotating shaft are fixed by a limit frame. The driving shaft and the rotating shaft are further fixed by a mounting plate. The oil filling holes provided on the root circle surface of the planetary gears are used to lubricate the space between the planetary gears and the rotating shaft, thereby reducing wear.

[0007] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: However, the planetary gear set adopts a conventional assembly method during assembly, and does not perform additional tooth limiting on the planetary gears during assembly. Therefore, during installation, tooth collision is prone to occur, and during disassembly, the planetary gears are prone to transmission with the sun gear or the ring gear, affecting disassembly. The convenience is insufficient and needs to be improved. Utility Model Content

[0010] (2) Technical solution

[0026] The embodiment of the present application effectively solves the technical problem of insufficient convenience in disassembly of existing planetary gear sets by providing an integrated planetary gear that is easy to disassemble and assemble. By setting a tooth limiting structure, the device can use the pin to limit the magnetic column into the magnetic groove when installing or disassembling the planetary gear shaft as a whole, the sun gear and the ring gear, so as to avoid the problem of transmission when the sun gear and the ring gear are removed, resulting in difficulty in disassembly, and the problem of difficulty in aligning the teeth when the planetary gear shaft as a whole, the sun gear and the ring gear are subsequently installed, thereby improving the convenience of installation and practicality. By providing a slot, the pin can be between the flat screw and the magnetic column, thereby limiting the magnetic column, avoiding the problem of poor operation quality caused by accidental friction between the magnetic column and the side wall of the shell when the integrated planetary gear is running, thereby improving reliability.

[0027] Example

[0028] like Figure 1 - Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of the inconvenience of disassembling the existing planetary gear set. The overall idea is as follows:

[0029] In response to the problems existing in the prior art, the present invention provides an integrated planetary gear that is easy to assemble and disassemble, including a housing 11. A plurality of planetary gear shafts 12 are provided on the side wall of the housing 11. A planetary gear body 13 is provided on the circumferential surface of each planetary gear shaft 12. Each planetary gear shaft 12 is partially exposed on the side wall of the housing 11 away from the planetary gear body 13. A through slot 14 is formed inside each planetary gear shaft 12.

[0030] A tooth limiting structure is slidably installed inside each through slot 14;

[0031] The tooth limiting structure includes a slider 15, and a slotted screw 16 is threadedly installed between each slider 15 and the planetary gear shaft 12. A stepped groove 17 is opened inside each slider 15, and a magnetic column 18 is slidably installed inside each stepped groove 17. A limiting ring 19 is fixedly installed on the circumferential surface of each magnetic column 18. By setting the tooth limiting structure, when the device is installing or disassembling the planetary gear shaft 12 as a whole, the sun gear 24 and the ring gear 25, the magnetic column 18 can be clamped into the magnetic groove 23 by using the pin 22 to limit the position. This avoids the problem of transmission and disassembly difficulty when the sun gear 24 and the ring gear 25 are disassembled, as well as the problem of difficulty in aligning the teeth when the planetary gear shaft 12 as a whole, the sun gear 24 and the ring gear 25 are subsequently installed, thereby improving the convenience of installation and improving practicality.

[0032] A slot 21 is provided inside each of the slotted screws 16 and the magnetic column 18, and a bayonet 22 is provided between each of the slotted screws 16 and the magnetic column 18. A plurality of magnetic slots 23 are provided inside the housing 11, and each of the magnetic columns 18 is adapted to the magnetic slot 23. A sun gear 24 is provided on the side wall of the housing 11, and the sun gear 24 is on the same side as the planetary gear body 13. By providing the slot 21, the bayonet 22 can be positioned between the slotted screw 16 and the magnetic column 18, thereby limiting the magnetic column 18, thereby avoiding the problem of poor operating quality caused by accidental friction between the magnetic column 18 and the side wall of the housing 11 when the integrated planetary gear is running, thereby improving reliability.

[0033] The sun gear 24 is located inside the planetary gear body 13 and is meshed with it. A ring gear 25 is provided on the side wall of the housing 11. The ring gear 25 is meshed with the planetary gear body 13. A limit frame 26 is provided between each planetary gear shaft 12. Each limit frame 26 is on the same side as the planetary gear body 13. When the staff needs to install the planetary gear shaft 12 as a whole, the sun gear 24 and the ring gear 25, the staff can first pick up the planetary gear shaft 12 and pass the planetary gear shaft 12 through the housing 11. Then the staff can use the slotted screw 16 to install the slider 15 inside the planetary gear shaft 12 again, and then work The operator can rotate the planetary gear shaft 12 so that the end of the magnetic column 18 of the slider 15 installed on the planetary gear shaft 12 can be aligned with the magnetic groove 23. At this time, the operator can remove the pin 22 and push the magnetic column 18 to one side of the planetary gear shaft 12 so that the magnetic column 18 is stuck in the magnetic groove 23. Then the operator can repeat the above steps to install the remaining planetary gear shafts 12 on the housing 11. At this time, the planetary gear body 13 on each planetary gear shaft 12 can be fixed to prevent rotation, thereby facilitating the subsequent installation of the sun gear 24 and the ring gear 25 for tooth docking, which is convenient for installation.

[0034] Working principle:

[0035] The first step is to remove the pin 22 from between the magnetic post 18 and the slotted screw 16 during disassembly, and push the magnetic post 18 toward the side of the planetary gear shaft 12 so that the magnetic post 18 is stuck in the magnetic groove 23. Then the staff can remove the sun gear 24 and the ring gear 25 first. Since the magnetic post 18 is stuck in the magnetic groove 23 at this time, it will limit the planetary gear shaft 12 and the planetary gear body 13. Therefore, it can also avoid the problem of transmission causing disassembly difficulty when the sun gear 24 and the ring gear 25 are disassembled. After the sun gear 24 and the ring gear 25 are disassembled, the slotted screw 16 can be removed from between the slider 15 and the planetary gear shaft 12. Then the staff can take the slider 15 out of the planetary gear shaft 12 as a whole. Then the staff can remove the planetary gear shaft 12 as a whole in a conventional disassembly form.

[0036] In the second step, when the staff needs to install the planetary gear shaft 12 as a whole, the sun gear 24 and the ring gear 25, the staff can first pick up the planetary gear shaft 12 and pass the planetary gear shaft 12 through the housing 11. Then the staff can use the flat screw 16 again to install the slider 15 inside the planetary gear shaft 12. Then the staff can rotate the planetary gear shaft 12 so that the end of the magnetic column 18 of the slider 15 installed on the planetary gear shaft 12 can be aligned with the magnetic groove 23. At this time, the staff can remove the pin 22 and push the magnetic column 18 to one side of the planetary gear shaft 12 so that the magnetic column 18 is stuck in the magnetic groove 23. Then the staff can repeat the above steps to install the remaining planetary gear shafts 12 on the housing 11. At this time, the planetary gear body 13 on each planetary gear shaft 12 can be fixed, which is also convenient for the subsequent installation of the sun gear 24 and the ring gear 25 to align the teeth, making installation convenient.

[0037] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
