Description

Technical Field

[0001] The utility model relates to the field of planetary reducers, and particularly relates to a planetary reducer with double output shafts for a gate. Background Technique

[0002] A planetary reducer is a power transmission mechanism that uses a gear speed converter to reduce the rotational speed of a motor to the required rotational speed and obtain a mechanism with a larger torque. The gear with fewer teeth on the transmission shaft of the planetary reducer meshes with the large gear on the output shaft to achieve the purpose of speed reduction. Ordinary reducers also have several pairs of gears meshing with the same principle to achieve the ideal speed reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

[0003] At present, when using a planetary reducer, since there are multiple gears in the planetary reducer, friction between the gears is likely to cause wear. Therefore, lubricating oil needs to be added to the gears in the planetary reducer. In the prior art, it is mostly added manually, and it is necessary to manually add lubricating oil to the planetary reducer every once in a while, which is too inconvenient. Moreover, when the lubricating oil is used up due to the high usage frequency of the planetary reducer, it is too late for manual addition, which will also affect the service life of the gears.

[0004] Therefore, it is very necessary to invent a planetary reducer with double output shafts for a gate to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention provides as Figures 1-4A double-output-shaft planetary reducer for a barrier gate, as shown, includes a housing 1. Inside the housing 1, a sun gear 2 is provided. Inside the sun gear 2, multiple planetary gears 3 are arranged. A rotating shaft 4 is connected inside each of the multiple planetary gears 3. Outside the sun gear 2, multiple fixing plates 5 are connected. The other ends of the multiple fixing plates 5 are connected to the inner wall of the housing 1. At the top of the housing 1, an oil filling box 6 is connected. At the bottom of the oil filling box 6, a first oil guiding pipe 7 is connected. Inside the oil filling box 6, a cotton wick 8 is connected. The cotton wick 8 is located inside the first oil guiding pipe 7. Outside the sun gear 2, an annular frame 10 is provided. An oil guiding opening 11 is formed on the surface of the annular frame 10. An oil inlet 12 is formed at the top of the sun gear 2. On the outer wall of the rotating shaft 4, a connecting plate 13 is provided. On the outside of the rotating shaft 4, a spline 14 is connected. A keyway corresponding to the spline 14 is formed inside the connecting plate 13. Corresponding threaded holes are formed on the surfaces of both the connecting plate 13 and the annular frame 10, and a bolt 15 is threadedly connected inside the threaded holes. Through the cotton wick 8 arranged in the oil filling box 6, the lubricating oil is adsorbed on its surface and slowly drips downward. At this time, the excess lubricating oil is inside the first oil guiding pipe 7. By sleeving the connecting plate 13 on the rotating shaft 4 and making the spline 14 on the rotating shaft 4 snap into the keyway on the connecting plate 13, when the planetary gear 3 rotates, it drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the connecting plate 13 to rotate through the spline 14, and the connecting plate 13 drives the annular frame 10 to rotate. When the oil guiding opening 11 on the annular frame 10 communicates with the first oil guiding pipe 7 and the oil inlet 12 respectively, the lubricating oil inside the first oil guiding pipe 7 enters the sun gear 2 through the oil guiding opening 11 and the oil inlet 12. When the planetary gear 3 meshes and rotates with the sun gear 2, the lubricating oil will adhere to the planetary gear 3 and the sun gear 2, which can conveniently automatically add lubricating oil to the sun gear 2 and the planetary gear 3, thereby effectively improving the service life of the sun gear 2 and the planetary gear 3. A oil return assembly 9 is provided on the bottom inner wall of the housing 1.

[0020] The oil return assembly 9 includes a second oil guiding pipe 91 connected to the bottom inner wall of the housing 1. An oil outlet 92 is formed at the bottom of the sun gear 2. At the bottom of the housing 1, a collection box 93 is connected. The collection box 93 is communicated with the second oil guiding pipe 91. On the left side of the collection box 93, a micro pump 94 is connected. At the bottom of the micro pump 94, a suction pipe 95 is connected.

The other end of the oil return pipe 96 is connected to the top of the oil filling box 6. When the oil guiding opening 11 on the annular frame 10 corresponds to the second oil guiding pipe 91 and the oil outlet 92 respectively, the excess lubricating oil inside the sun gear 2 enters the collection box 93 through the oil outlet 92, the oil guiding opening 11 and the second oil guiding pipe 91. By using the micro pump 94 to extract the lubricating oil and retransmitting it to the oil filling box 6 through the oil return pipe 96, it is convenient to collect the excess lubricating oil.

[0021] Semicircular protective plates 16 are commonly connected to both the left and right sides of the first oil guide pipe 7 and the second oil guide pipe 91, which can facilitate the protection of the lubricating oil, so that the lubricating oil can be centrally collected.

[0022] An oil receiving hopper 17 is connected inside the collection box 93, and the other end of the extraction pipe 95 is connected to the bottom of the oil receiving hopper 17, which can facilitate the centralized guiding of the lubricating oil entering the collection box 93.

[0023] A filter screen 18 is arranged inside the collection box 93. Sliders 19 are connected to both the left and right sides of the filter screen 18. Sliding grooves corresponding to the sliders 19 are provided on both the left and right inner side walls of the collection box 93. A pick-and-place opening corresponding to the filter screen 18 is provided on the front side of the collection box 93. By providing the filter screen 18, it is convenient to filter the recycled lubricating oil. And by pulling the filter screen 18, the filter screen 18 pulls the slider 19, causing the slider 19 to move in the sliding groove, and the filter screen 18 can be taken out of the collection box 93, and vice versa, the filter screen 18 can be installed.

[0024] The working principle of the present utility model:

[0025] Through the cotton core 8 arranged in the fuel filling box 6, the lubricating oil is adsorbed on its surface and slowly drips down the lubricating oil. At this time, the excess lubricating oil is in the first oil guide pipe 7. By sleeving the connecting plate 13 on the rotating shaft 4 and making the spline 14 on the rotating shaft 4 snap into the key groove on the connecting plate 13, when the planetary gear 3 rotates, it drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the connecting plate 13 to rotate through the spline 14, and the connecting plate 13 drives the annular frame 10 to rotate. When the oil guide ports 11 on the annular frame 10 are respectively communicated with the first oil guide pipe 7 and the oil inlet 12, the lubricating oil in the first oil guide pipe 7 enters the sun gear 2 through the oil guide port 11 and the oil inlet 12. When the planetary gear 3 meshes and rotates with the sun gear 2, the lubricating oil will adhere to the planetary gear 3 and the sun gear 2. When the oil guide ports 11 on the annular frame 10 correspond to the second oil guide pipe 91 and the oil outlet 92 respectively, the excess lubricating oil in the sun gear 2 enters the collection box 93 through the oil outlet 92, the oil guide port 11 and the second oil guide pipe 91.
