Description

Technical Field

[0001] The invention relates to the technical field of a waterproof structure of a reducer, and in particular to a waterproof planetary gear reducer. Background Art

[0002] Planetary gear reducer is a type of reducer currently available. It is assembled through a sun gear, a frame and planetary gears, and reduces the speed of the motor through different input and output methods, so as to control the speed within the required range. It is also one of the main deceleration methods for motors now. If necessary, multiple sets of planetary gear reducers can be connected and coordinated with each other.

[0003] Due to the characteristics of planetary gears, once one of the gears is invaded by water, all the gears will be adhered to water. Long-term water on the gears will cause rust on the gear surface. The strength and operating stability of the rusted gears will drop sharply. The planetary gear reducer is generally connected to the inside of the motor, and water ingress problems rarely occur. However, once water ingress occurs, it is not convenient to carry out timely maintenance, which increases the probability of motor and planetary gear failure. For this reason, a waterproof planetary gear reducer is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a waterproof planetary gear reducer, which can automatically discharge water to avoid water accumulating on the gears for a long time and causing rust and other factors to the gears.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a waterproof planetary gear reducer, comprising an outer frame, one end of the outer frame is fixedly connected to a processing column, the processing column is an annular structure, an inner groove is provided inside the processing column, and an annular fixing plate is rotatably provided in the inner groove;

[0006] A water-absorbing sponge is fixedly connected to a side wall of the fixed plate, a semicircular water tank is provided in the upper side wall of the outer frame, and a semicircular water inlet tank is provided through the upper side wall of one end of the outer frame away from the treatment column, and the water inlet tank is communicated with the inside of the water tank;

[0007] The bottom side wall of the water tank is an inclined structure, the water tank is communicated with the inside of the inner tank, and the bottom side wall of the treatment column is penetrated by two drainage grooves.

[0008] Preferably, the water can be absorbed by the established absorbent sponge to achieve preliminary treatment of the water, and then the water in the absorbent sponge is discharged from the drain groove, thereby achieving the function of waterproof drainage and avoiding problems such as damage to the equipment due to water. The invading water can be guided through the water groove and finally absorbed by the absorbent sponge, thereby achieving the function of waterproof drainage.

[0009] As a preferred technical solution of the present invention, a gear ring is fixedly connected to the inner wall of the outer frame, and four planetary gears are meshedly connected to the outer frame through the gear ring. A sun gear is meshedly connected in the middle of the four planetary gears, and one end of the four planetary gears is rotatably connected to an output cross. A connecting plate is fixedly connected to the outer wall of the output cross near the edge, and the connecting plate is an L-shaped structure, and one end of the connecting plate is fixedly connected to an annular docking plate.

[0010] Preferably, the effect of rotational deceleration output is achieved by setting up an output cross, and at the same time, two connecting plates are fixedly connected to the output cross, so that the connecting plates can be driven to rotate synchronously through the output cross, thereby driving the docking plate to rotate, and the water-absorbing sponge is driven to rotate through the rotation of the docking plate.

[0011] As a preferred technical solution of the present invention, an annular through groove is opened through the middle of the inner wall of the treatment column, and the docking plate is a T-shaped structure. One end of the docking plate extends through the through groove into the inner groove and is fixedly connected to the middle of the top side wall of the fixed plate. An extrusion water outlet plate is fixedly connected to the inner wall of the inner groove and at one side edge close to the drainage groove, and the extrusion water outlet plate is an upward inclined structure.

[0012] Preferably, because the docking plate is connected to the fixed plate through the through groove, when the docking plate rotates, it can drive the water-absorbing sponge to rotate synchronously, and as the water-absorbing sponge rotates, it will contact the water-extruding plate, and at the same time, the water-absorbing sponge will also be pressed by the water-extruding plate. As the water-absorbing sponge rotates, the water absorbed inside it can be squeezed out, and the squeezed water will eventually be discharged from the drainage groove, thereby realizing the drainage function, and at the same time, because the inner wall of the treatment column is an inclined structure.

[0013] As a preferred technical solution of the present invention, an output shaft is fixedly connected to the middle of the output cross, the inner wall of the processing column is set as an inclined structure and has filter holes, and a water stop ring is fixedly connected to the inside of the processing column and at the connection with the outer frame, and the height of the water stop ring is -cm higher than the gear ring.

[0014] Preferably, an annular water stop ring is fixed on the inner wall of the treatment column to block water entering the treatment column, thereby preventing water from entering the outer frame. The water entering the treatment column enters the inner groove through the filter hole and is finally absorbed by the absorbent sponge, thereby preventing water from entering the outer frame.

[0015] As a preferred technical solution of the present invention, a side wall of the outer frame is provided with a filling box, and the bottom end of the filling box is detachably connected to a conveying plate, and a storage groove is opened inside the filling box, and the storage groove is communicated with the inside of the conveying plate, and side panels are fixedly connected on the opposite side walls in the conveying plate and close to the storage groove, and the inner wall of the side panel is an inclined structure, and a follower conical plate is provided between the two side panels, and the follower conical plate is a trapezoidal structure, and the outer wall of the follower conical plate is fixedly connected to a rubber pad, and the opposite side walls of the two side panels are evenly fixedly connected with stepped protrusions, and the protrusions are fitted with the rubber pads, and the top side walls of the follower conical plate near the two ends are fixedly connected with springs, and the end of the spring away from the follower conical plate is fixedly connected to a cross plate.

[0016] Preferably, the gap between the two side plates can be sealed by setting up side plates and docking plates, and the spring can ensure that the follower conical plate fits tightly against the inner wall of the side plate, thereby preventing the lubricating oil in the storage tank from entering the outer frame from the conveying plate. By fixing the protrusion on the inner wall of the side plate, the rubber pad will be deformed when it fits tightly against the protrusion, which can effectively improve the sealing effect.

[0017] As a preferred technical solution of the present invention, the horizontal plate is fixedly connected to the inner wall of the conveying plate close to the storage tank at both ends, the side walls of the conveying plate close to both ends are fixedly connected with electromagnets, and the follower conical plate is fixedly connected to one end of the electromagnet with an iron block.

[0018] Preferably, the electromagnet is energized when necessary to magnetically attract the iron block, thereby pulling the follower conical plate downward from the middle of the two side plates, thereby leaving a sufficient gap between the follower conical plate and the side plates, so that lubricating oil can be injected from the conveying plate into the outer frame, thereby achieving the effect of lubricating the sun gear, planetary gears and gear ring.

[0019] As a preferred technical solution of the present invention, an annular connecting flange is fixedly connected to the outer wall of the outer frame close to the water inlet trough, a cover is provided at one end of the outer frame away from the treatment column, a groove is provided on the side of the cover opposite to the outer frame, the cover is sleeved on one end of the outer frame through the groove, a connecting flange is fixedly connected to the outer wall of the cover, the two connecting flanges are detachably connected by screws, an input shaft groove is provided through the middle of the cover, and an input structure is inserted into the input shaft groove.

[0020] Preferably, because the water inlet groove is located on one side of the connecting flange, the water inlet groove will be wrapped and sealed after the connection, thereby reducing the probability of water entering the outer frame, and at the same time, the water entering therein can be sent into the water tank through the water inlet groove.

[0021] The present invention has the following advantages: when entering, water will enter the inner part from the outer part, and then the water entering the inner part will flow along its inclined side wall and finally enter the inner part, and then the water will be absorbed, so as to avoid the accumulation of water and the influence on the internal parts, and because it is connected with the outer part and connected with the inner part at the same time, when it follows the rotation, it will also drive the synchronous rotation, and will also drive the rotation of the outer part through the transmission of the inner part, because it is a semicircular structure, so as to make its dry position contact with water with the rotation of the inner part, and by being able to squeeze out water from the rotating inner part, it is avoided that the inner part is saturated with water, and the squeezed water will be discharged to the outside from the outer part, so as to realize the function of waterproofing and drainage;

[0022] A circle is fixed on the inner wall, and the inner wall is set into a cone-shaped inclined structure, and filter holes are opened on it. When water enters, the water flows outward along the slope and is blocked at the same time. Therefore, the water on the inner wall will enter from the filter hole and be absorbed and then discharged.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1-6 The present invention discloses a waterproof planetary gear reducer, comprising an outer frame 1, one end of which is fixedly connected to a processing column 2, the processing column 2 is an annular structure, an inner groove 13 is provided inside the processing column 2, an annular fixed plate 14 is rotatably set in the inner groove 13, a water-absorbing sponge 12 is fixedly connected to a side wall of the fixed plate 14, a semicircular water groove 11 is provided in the upper side wall of the outer frame 1, a semicircular water inlet groove 9 is provided through the upper side wall of the end of the outer frame 1 away from the processing column 2, the water inlet groove 9 is communicated with the inside of the water groove 11, the bottom side wall of the water groove 11 is inclined, the water groove 11 is communicated with the inside of the inner groove 13, two drainage grooves 21 are provided through the bottom side wall of the processing column 2, an extrusion water outlet plate 22 is fixedly connected to the inner wall of the inner groove 13 and at one side edge close to the drainage groove 21, and the extrusion water outlet plate 22 is an upwardly inclined structure.

[0033] Preferably, a fixing plate 14 is provided in the inner groove 13, and an annular water-absorbing sponge 12 is fixed on one side of the fixing plate 14. Water seeping in from the two connecting flanges 3 will be sent into the water groove 9 from the water inlet groove 9, and then flow into the inner groove 13 along the water groove 11. At this time, the water-absorbing sponge 12 will absorb the water, thereby achieving preliminary cleaning of the water, and the water can be guided through the water inlet groove 9 and the water groove 11, so as to avoid water accumulation and reduce the contact time between the equipment and the water, thereby avoiding the impact of water on the equipment. At the same time, the water-extruding plate 22 provided will squeeze the water-absorbing sponge 12, and the water adsorbed in the water-absorbing sponge 12 can be squeezed out by the squeezing force and discharged from the drainage groove 21, so as to avoid the water-absorbing sponge 12 becoming saturated with water and affecting the effect of subsequent water absorption treatment.

[0034] Please refer to Figure 1 , 3 -5, the inner wall of the outer frame 1 is fixedly connected with a gear ring 7, the outer frame 1 is meshedly connected with four planetary gears 8 through the gear ring 7, the four planetary gears 8 are meshedly connected with a sun gear 10 in the middle, one end of the four planetary gears 8 is rotatably connected with an output cross 17, the outer wall of the output cross 17 and near the edge is fixedly connected with a connecting plate 18, the connecting plate 18 is an L-shaped structure, one end of the connecting plate 18 is fixedly connected with an annular docking plate 16, an annular through groove 15 is opened in the middle of the inner wall of the processing column 2, the docking plate 16 is a T-shaped structure, one end of the docking plate 16 passes through the through groove 15 and extends into the inner groove 13 and is fixedly connected to the middle of the top side wall of the fixed plate 14.

[0035] As a preference: through the rotation of the four planetary gears 8, the output cross 17 and the connecting plate 18 can be driven to rotate synchronously, thereby driving the water-absorbing sponge 12 to rotate via the docking plate 16 and the fixed plate 14. As the water-absorbing sponge 12 rotates, different parts of the water-absorbing sponge 12 can continuously contact and absorb water in the water tank 11. At the same time, as the water-absorbing sponge 12 rotates, it cooperates with the water squeezing plate 22 to achieve the effect of continuous squeezing and drainage.

[0036] Please refer to Figure 5 The output shaft 19 is fixedly connected to the middle of the output cross 17, the inner wall of the processing column 2 is set as an inclined structure and has filter holes, and a water stop ring 20 is fixedly connected to the connection between the processing column 2 and the outer frame 1. The height of the water stop ring 20 is 2-5 cm higher than the gear ring 7.

[0037] Preferably, a water stop ring 20 fixed on the inner wall of the treatment column 2 can block water intruding from the treatment column 2 from entering the outer frame 1, thereby preventing water from causing water corrosion to the planetary gears 8, the gear ring 7 and the sun gear 10. At the same time, since the inner wall of the treatment column 2 is an inclined structure, water will flow outward, then enter the inner groove 13 through the filter holes on the inner wall of the treatment column 2 and finally be absorbed by the absorbent sponge 12.

[0038] Please refer to Figure 6 A material injection box 6 is provided on one side wall of the outer frame 1, and a conveying plate 24 is detachably connected to the bottom end of the material injection box 6. A storage groove 23 is provided inside the material injection box 6, and the storage groove 23 is communicated with the inside of the conveying plate 24. Side plates 25 are fixedly connected to the opposite side walls in the conveying plate 24 and close to the storage groove 23. The inner wall of the side plate 25 is an inclined structure, and a follower cone plate 26 is provided between the two side plates 25. The follower cone plate 26 is a trapezoidal structure, and the outer wall of the follower cone plate 26 is fixedly connected with a rubber pad. The side walls opposite to each side plate 25 are evenly fixedly connected with stepped protrusions, and the protrusions fit with the rubber pads. The top side walls of the follower conical plate 26 near both ends are fixedly connected with springs 28. One end of the spring 28 away from the follower conical plate 26 is fixedly connected with a cross plate 27. The cross plate 27 is fixedly connected to the conveying plate 24 and the inner wall near the storage tank 23 through both ends. The side walls of the conveying plate 24 near both ends are fixedly connected with electromagnets 29. The follower conical plate 26 and one end of the electromagnet 29 are fixedly connected with iron blocks.

[0039] Preferably, the electromagnet 29 is energized when necessary, and the electromagnet 29 attracts the magnet to pull the follower cone plate 26 out from the middle of the side plate 25, so that a sufficient gap is left between the follower cone plate 26 and the inner wall of the side plate 25, so that the lubricating oil in the storage tank 23 flows out from the gap and is sent into the outer frame 1 through the conveying plate 24, and the comprehensive lubrication effect is achieved through the transmission characteristics of the planetary gear 8, the ring gear 7 and the sun gear 10.

[0040] Please refer to Figure 1-2 An annular connecting flange 3 is fixedly connected to the outer wall of the outer frame 1 near the water inlet groove 9, a cover 4 is provided at one end of the outer frame 1 away from the processing column 2, a groove is provided on the side of the cover 4 opposite to the outer frame 1, the cover 4 is sleeved on one end of the outer frame 1 through the groove, a connecting flange 3 is fixedly connected to the outer wall of the cover 4, the two connecting flanges 3 are detachably connected by screws, an input shaft groove 5 is provided through the middle of the cover 4, and an input structure is inserted in the input shaft groove 5.

[0041] Preferably, a groove is formed in the cover 4, and the cover 4 can be sleeved on one end of the outer frame 1 through the groove, and then the two flanges are connected using screws, and rubber is fixed to the inner wall of one end of the cover 4. After the sleeve connection, the rubber fits tightly on one end of the outer frame 1 to achieve a sealing effect, thereby preventing water from entering the outer frame 1 from the joint between the groove and the outer frame 1.

[0042] Specifically, when the present invention is used, after water enters between the two connecting flanges 3, it will fall into the water tank 9 from the water inlet groove 9. Because the equipment is a circular structure, most of the water falls from the top, so the water inlet groove 9 is opened on the upper side wall mainly to achieve direct contact with water. The water entering the water tank 11 will flow and finally enter the inner tank 13 to be absorbed by the water-absorbing sponge 12. In this way, it is possible to avoid water accumulation and damage to the equipment such as rust. Because the two connecting flanges 3 are located above the water inlet groove 9 after closing, water will only enter the water inlet groove 9 and will not flow to the surroundings. If necessary, rubber pads can be set on the inner walls of the two connecting flanges 3 to increase the waterproof effect. The components such as the water inlet groove 9 and the water tank 11 are set to achieve drainage and are the last resort for waterproofing the equipment. Therefore, according to actual needs, other waterproof components can be added to the outer wall of the outer frame 1 to improve the waterproof performance;

[0043] As the planetary gear 8 runs, the output cross 17 is driven to rotate, and the water-absorbing sponge 12 is driven to rotate via the connecting plate 18 and the docking plate 16. As the water-absorbing sponge 12 rotates and cooperates with the water-extruding plate 22, the effect of squeezing and draining water is achieved. No additional power source is required, which saves energy consumption. In this way, the original rotation capacity can be consumed, and an additional deceleration effect is added on the basis of the original planetary gear 8 reducer, thereby improving the practicality of the equipment.

[0044] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

[0045] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
