Specific embodiments

[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0019] Embodiment: Please refer to Figure 1 - Figure 5, the present utility model provides a technical solution: a speed reducer facilitating lubricating oil filling, comprising: a speed reducer body 1; a mounting device 2, the outer wall of the mounting device 2 being fixedly connected to the outer wall of the speed reducer body 1; an insertion block 3, the outer wall of the insertion block 3 being slidably connected to the outer wall of the mounting device 2; the speed reducer body 1 includes a coil drive group 11, a toothed ring 12 being fixedly connected to the outer wall of the coil drive group 11, a planetary gear 14 being meshed with the outer wall of the toothed ring 12, an output shaft 15 being rotatably connected to the inner wall of the planetary gear 14, a limiting sleeve 16 being rotatably connected to the outer wall of the output shaft 15, and the output end of the coil drive group 11 being fixedly connected to a transmission gear 13; the toothed ring 12 includes an internal gear 121, a flow nozzle 122 being symmetrically fixedly connected to the outer wall of the internal gear 121, a flow channel 123 being provided in the inner wall of the internal gear 121, a raised block 124 being fixedly connected to the inner wall of the internal gear 121, an oil outlet hole 125 being provided in the inner wall of the internal gear 121 and being communicated with the flow channel 123. Lubricating oil is injected through the flow nozzle 122 to lubricate the gear running part inside the speed reducer body 1. After the lubricating oil is injected through the flow nozzle 122 provided on the internal gear 121 of the toothed ring 12, the lubricating oil will enter the flow channel 123. When entering, part of the oil liquid enters the tooth groove position of the internal gear 121 through the oil outlet hole 125 at the top, and the remaining oil liquid that does not enter fills the flow channel 123 due to the pressure of the subsequently injected oil liquid, its own gravity, and its own fluidity. When the oil liquid passes through the blocking position of the raised block 124, the suddenly emerging blocking part will change the flow direction of the oil liquid, causing part of the oil liquid to enter the tooth groove again through the oil outlet holes 125 on both sides of the flow channel 123. When the speed reducer body 1 is used again, the oil liquid is brought to the inner wall of the assembly by the planetary gear 14 to lubricate components such as the transmission gear 13 and the planetary gear 14. Moreover, the flow channel 123 and the oil outlet hole 125 communicated with the outside are provided, so that the expanded gas can be discharged, thereby protecting the internal components of the speed reducer body 1.

[0020] The transmission gear 13 is meshed with the planetary gear 14, the planetary gear 14 is meshed with the internal gear 121, the outer wall of the internal gear 121 is fixedly connected to the outer wall of the coil drive group 11, and the side of the internal gear 121 away from the coil drive group 11 is fixedly connected to the outer wall of the limiting sleeve 16.

[0021] The installation device 2 includes a fixing plate 21. A positioning block 22 is inserted into the outer wall of the fixing plate 21. A compression spring 23 is fixedly connected to the outer wall of the positioning block 22. One end of the compression spring 23 away from the positioning block 22 is fixed with a connecting plate 24. One end of the connecting plate 24 away from the compression spring 23 is fixedly connected to a push plate 25. The outer wall of the top of the fixing plate 21 is fixedly connected to a clamping plate 26. An oil guide groove 27 is opened on the outer wall of the top of the fixing plate 21. The outer wall of the clamping plate 26 is slidably connected to the outer wall of the internal gear 121. The outer wall of the clamping plate 26 is slidably connected to the outer wall of the limiting sleeve 16. The outer wall of the push plate 25 is slidably connected to the outer wall of the coil driving group 11. Under the action of the compression spring 23, the push plate 25 is pushed through the connecting plate 24, so that the push plate 25 plays a role in stabilizing and supporting the coil driving group 11. The clamping plate 26 is slidably connected to the outer walls of the internal gear 121 and the limiting sleeve 16, playing a role in clamping and limiting from the other side direction, so that the reducer body 1 can be quickly and stably placed on the installation device 2. At the same time, the oil guide groove 27 is arranged below the flow nozzle 122 at the bottom of the internal gear 121 for guiding the flow of lubricating oil.

[0022] The insertion block 3 includes an arc plate 31. Sliding blocks 32 are fixedly connected to both sides of the arc plate 31. A positioning sleeve 33 is fixedly connected to the outer wall of the bottom of the arc plate 31. A plugging column 34 is arranged inside the positioning sleeve 33. The outer wall of the top of the plugging column 34 is fixedly connected to the inner wall of the arc plate 31. The outer walls of the sliding blocks 32 and the arc plate 31 are both slidably connected to the outer wall of the clamping plate 26. The outer walls of the positioning sleeve 33 and the plugging column 34 are both slidably connected to the outer wall of the flow nozzle 122. The arc plate 31 of the insertion block 3 is limited by sliding connection with the clamping plate 26 through the sliding blocks 32 on both sides, and the positioning sleeve 33 and the plugging column 34 are slidably connected to the outer wall of the flow nozzle 122 at the top of the internal gear 121 to ensure the stability during lubricating oil filling.

[0023] Working principle:

[0024] During use, the coil drive group 11 in the speed reducer body 1 is started, and the transmission gear 13 at its output end drives the planetary gear 14 to rotate. The planetary gear 14 meshes with the internal gear 121 of the gear ring 12, thereby achieving speed reduction and power transmission. The output shaft 15, as a shaft body, has three evenly distributed columnar objects at one end, and this part is inserted into the planetary gear 14 to obtain rotational power. The other end is a thicker columnar object with a keyway, and this position extends out of the limit sleeve 16 and is connected to other components that require power. The output shaft 15 outputs power as the planetary gear 14 rotates, and the limit sleeve 16 plays a role in limiting and supporting the output shaft 15. Before and after the use of the speed reducer body 1, lubricating oil can be injected through the circulation nozzle 122 to lubricate the gear operating parts inside the speed reducer body 1. The circulation nozzle 122 provided on the internal gear 121 of the gear ring 12 is used to inject lubricating oil. After the lubricating oil enters the circulation groove 123, when it enters, part of the oil enters the tooth grooves of the internal gear 121 through the oil outlet hole 125 at the top, and the remaining oil that does not enter fills the circulation groove 123 due to the pressure of the subsequently injected oil, its own gravity, and its own fluidity. When the oil passes through the position blocked by the raised block 124, the suddenly appeared blocked part will change the flow direction of the oil, causing part of the oil to enter the tooth grooves again through the oil outlet holes 125 on both sides of the circulation groove 123. When the speed reducer body 1 is used again, the oil is brought to the inner wall of the component by the planetary gear 14 to lubricate components such as the transmission gear 13 and the planetary gear 14. The remaining oil will gradually flow out from the circulation nozzle 122 at the bottom of the internal gear 121 over time. The grooved internal gear 121 also has a function during use. Since the speed reducer body 1 using the planetary gear 14 is difficult to operate for a long time, the friction during the transmission process will heat the internal air, thereby expanding the internal gas, which is likely to cause the gears to be misaligned. The provided circulation groove 123 and oil outlet hole 125 communicating with the outside allow the expanded gas to be discharged, thereby protecting the internal components of the speed reducer body 1.

[0025] The fixing plate 21 in the installation device 2 is used to fix and support other components. The positioning block 22 is fixed in position. Under the action of the compression spring 23, the push plate 25 is pushed through the connecting plate 24, so that the push plate 25 plays a role in stabilizing and supporting the coil drive group 11. The clamping plate 26 is slidably connected to the outer walls of the internal gear 121 and the limit sleeve 16, and plays a role in clamping and limiting from the other side direction, enabling the speed reducer body 1 to be quickly and stably placed on the installation device 2, providing a more stable working position for the speed reducer body 1. At the same time, an oil guiding groove 27 is provided below the circulation nozzle 122 at the bottom of the internal gear 121 to guide the flow of lubricating oil and facilitate the recovery of excess lubricating oil.

[0026] The arc-shaped plate 31 of the insertion block 3 is limited by slidingly connecting with the clamping plates 26 on both sides through the sliding blocks 32. The positioning sleeve 33 and the insertion column 34 are slidingly connected with the outer wall of the flow nozzle 122 at the top of the internal gear 121 to ensure stability during lubricating oil filling. The design of the insertion block 3 ensures that it is difficult for dust to accumulate and block the internal space of the internal gear 121 during non-filling processes.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Structures, devices, and operation methods that are not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
