DETAILED DESCRIPTION
[0019] The utility model provides Figures 1 to 3 The planetary reducer shown is for a four-way shuttle, and includes a housing 1, a sun gear 4 is provided inside the housing 1, a ring gear 19 is fixedly connected to the inside of the housing 1, one end of the housing 1 is rotatably connected to a first shaft 2, and the sun gear 4 is fixedly connected to the first shaft 2.
[0020] Housing 1 houses a planetary support plate 5, fixedly connected to a support shaft 7. Support shaft 7 rotatably connects a planetary gear 16, which meshes between sun gear 4 and ring gear 19. Planetary support plate 5 defines an inner cavity 6. Housing 1 also rotatably connects a second shaft 3 to which planetary support plate 5 is fixedly connected. In practical use, three sets of planetary support plates 5, support shafts 7, and planetary gears 16 are provided.
[0021] The three planetary support plates 5 are evenly distributed around the second shaft 3 to form a planetary bracket structure, and only one of the planetary support plates 5 is provided with an inner cavity 6 and other corresponding structures.
[0022] The operator can inject lubricating oil into the inner cavity 6 during regular maintenance.
[0023] A delivery channel 9 is defined within the support shaft 7, and a fluid hole 8 is defined on the inner wall of the delivery channel 9. The inner cavity 6 is connected to the delivery channel 9 via the fluid hole 8. An annular groove 17 is defined on the inner ring of the planetary gear 16, and a circular hole 18 is defined on the inner wall of the annular groove 17. The circular hole 18 penetrates the outer ring of the planetary gear 16, and the delivery channel 9 cooperates with the annular groove 17. Specifically, when the support shaft 7 rotates to the bottom position within the housing 1, the fluid hole 8 is located at the bottom end of the inner cavity 6. Lubricating fluid within the inner cavity 6 can flow from the fluid hole 8 into the delivery channel 9 and be delivered to the inner wall of the annular groove 17. Then, during the rotation of the planetary gear 16, the fluid is flung from the circular hole 18 onto the ring gear 19 and the sun gear 4, achieving the purpose of automatic lubrication.
[0024] By providing structures such as the inner cavity 6, the conveying channel 9 and the liquid hole 8, the lubricating liquid is thrown from the circular hole 18 to the ring gear 19 and the sun gear 4 during the rotation of the planetary gear 16, thereby achieving the purpose of automatic lubrication and improving the efficiency of the planetary reducer, especially when the planetary reducer is used on a four-way shuttle car under heavy load.
[0025] To prevent the lubricating fluid from flowing out of the inner cavity 6, a chute 10 is provided on the support shaft 7. One end of the chute 10 extends through the outer wall of the support shaft 7, and the other end of the chute 10 communicates with the inner cavity 6. The chute 10 is located between the fluid hole 8 and the planetary gear 16. A slide post 11 is provided inside the chute 10 for sliding movement. The slide post 11 has a through hole 13 formed therein, and the through hole 13 cooperates with the delivery channel 9. One end of the slide post 11 located inside the inner cavity 6 is fixedly connected to a limit plate 15. A spring 14 is sheathed on the outside of the slide post 11. One end of the spring 14 is fixedly connected to the limit plate 15, and the other end of the spring 14 is fixedly connected to the inner wall of the inner cavity 6.
[0026] One end of the slide post 11 away from the limiting plate 15 is fixedly connected to the magnetic block 12 , and the bottom of the inner wall of the housing 1 is fixedly connected to the arc-shaped magnet 20 , which repel each other with the magnetic block 12 .
[0027] Specifically, when support shaft 7 rotates to the bottom position inside housing 1, fluid hole 8 is located at the bottom end of inner cavity 6, and arc-shaped magnet 20 corresponds to magnetic block 12. Under the action of the repulsive force, magnetic block 12 drives slide post 11 toward inner cavity 6, and through hole 13 is connected to delivery channel 9. At this time, the lubricating fluid inside inner cavity 6 can flow from fluid hole 8 into delivery channel 9 and be delivered to the inside of annular groove 17. When arc-shaped magnet 20 and magnetic block 12 are offset, the return force of spring 14 causes slide post 11 to return to its original position, through hole 13 and delivery channel 9 are offset, and slide post 11 isolates delivery channel 9. The lubricating fluid delivered to annular groove 17 is then thrown from circular hole 18 to ring gear 19 and sun gear 4 during the subsequent rotation of planetary gear 16.
[0028] By providing structures such as the slide post 11 , the arc-shaped magnet 20 and the magnetic block 12 , intermittent outflow of lubricating fluid is achieved, thereby avoiding waste.
