Description

Technical Field

[0001] This utility model belongs to the field of planetary gear equipment technology, and in particular relates to an adaptive load balancing planetary gear equipment. Background Technology

[0002] Planetary gears are gear systems that, in addition to rotating around their own axis like fixed-axis gears, also have their axis of rotation rotating around the axes of other gears along with the planet carrier. Rotation around their own axis is called "rotation," and rotation around the axes of other gears is called "revolution," just like the planets in the solar system, hence the name.

[0003] The utility model disclosed in CN222163488U is a planetary gear set structure, which includes a planetary gear mechanism, a circulation mechanism and a transmission mechanism. The planetary gear mechanism includes a housing, a planetary gear set, a first transmission shaft, a second transmission shaft and a port. The planetary gear set is arranged inside the housing, and the upper end of the planetary gear set is connected to the first transmission shaft.

[0004] The aforementioned application document describes a method where a rotating shaft drives the blades to rotate, which in turn causes the lubricating oil in the vertical pipe to circulate, providing hydraulic power. This allows the lubricating oil to circulate between the housing and the lubricating oil tank through the delivery pipe. However, the hydraulic power generated by the rotation of the blades is limited, which may prevent the lubricating oil from flowing smoothly between the delivery pipe, the housing, and the lubricating oil tank. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive load balancing planetary gear device that solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an adaptive load balancing planetary gear device, comprising a housing and a lubricating oil tank. A planetary gear set is housed inside the housing. A drive shaft is rotatably connected through the top of the housing, and a driven shaft is fixedly connected through the bottom of the housing. A lubricating oil circulation mechanism is located at the top of the housing. The lubricating oil circulation mechanism includes a pressure chamber, a drive gear, a rotating shaft, and a connecting pipe. The pressure chamber is fixedly connected to the top of the housing and contains a return spring. A piston rod is slidably connected to the pressure chamber via the return spring piston. A pressure plate is fixedly connected to the end of the piston rod away from the pressure chamber. An oil suction pipe is fixedly connected through the side of the pressure chamber, and an oil delivery pipe is fixedly connected through the bottom of the pressure chamber. Both the oil suction pipe and the oil delivery pipe contain one-way valves. The drive gear is fixedly connected to the surface of the drive shaft. The rotating shaft is rotatably connected to the top of the housing, and a driven gear is fixedly connected to the surface of the rotating shaft. An eccentric ring is fixedly connected to the top of the rotating shaft. The connecting pipe is fixedly connected through the bottom of the housing. A self-lubricating component is located at the end of the pressure plate away from the piston rod.

[0007] Furthermore, the driven shaft is connected to the driving shaft via a planetary gear set, and the end of the pressure plate away from the piston rod is close to the eccentric ring. When the driving shaft rotates, it will drive the driven shaft to rotate through the planetary gear set. When the eccentric ring rotates with the rotating shaft, it will repeatedly squeeze the pressure plate to move to the right.

[0008] Furthermore, the one-way valve inside the oil suction pipe is unidirectionally open to the inside of the pressure chamber. The end of the oil suction pipe away from the pressure chamber is connected to the lubricating oil tank through and fixedly connected. When a negative pressure is formed inside the pressure chamber, the lubricating oil in the lubricating oil tank will be drawn through the oil suction pipe.

[0009] Furthermore, the end of the oil delivery pipe away from the pressure chamber is connected to the outer shell through and fixedly, and the one-way valve inside the oil delivery pipe is unidirectionally open towards the outer shell. When pressure is applied to the pressure chamber, the lubricating oil inside will be transported to the outer shell through the oil delivery pipe.

[0010] Furthermore, the driving gear meshes with the driven gear, and the end of the connecting pipe away from the outer casing is connected to the lubricating oil tank through and fixedly connected. The rotation of the driving gear will drive the driven gear to rotate, and excess lubricating oil in the outer casing can flow back to the lubricating oil tank through the connecting pipe.

[0011] Furthermore, the self-lubricating component includes an oil reservoir, which is located inside the pressure plate. Ball bearings are provided on the inner wall of the oil reservoir, and an oil injection pipe is fixedly connected through and to the top of the oil reservoir.

[0012] Furthermore, the side of the ball away from the oil storage cavity protrudes from the pressure plate, and there are five sets of balls in total. When the eccentric ring is pressed against the pressure plate, it will come into contact with the five sets of balls.

[0013] This utility model has the following beneficial effects: 1. This utility model, by setting up a lubricating oil circulation mechanism, achieves sufficient pressure through the cooperation of components such as eccentric ring, pressure plate, piston rod, and pressure chamber, so that the oil suction pipe draws lubricating oil from the lubricating oil tank and discharges it into the outer shell through the oil delivery pipe. Excess lubricating oil in the outer shell flows back to the lubricating oil tank through the connecting pipe, thus forming a circulation flow. This lubricates the planetary gear set while carrying away the heat generated by friction.

[0014] 2. By incorporating a self-lubricating component, this utility model ensures that as the eccentric ring rotates with the shaft and repeatedly presses against the pressure plate, the surface of the eccentric ring remains lubricated through the cooperation of the ball bearings and the oil storage cavity. This reduces wear between the eccentric ring and the pressure plate and improves the overall service life of the device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] Please see Figures 1-5 As shown, this utility model is an adaptive load balancing planetary gear device, including a housing 1 and a lubricating oil tank 5. A planetary gear set 2 is arranged inside the housing 1. A drive shaft 3 is rotatably connected through the top of the housing 1, and a driven shaft 4 is fixedly connected through the bottom of the housing 1. A lubricating oil circulation mechanism 6 is arranged at the top of the housing 1. The lubricating oil circulation mechanism 6 includes a pressure chamber 61, a drive gear 67, a rotating shaft 68, and a connecting pipe 611. The pressure chamber 61 is fixedly connected to the top of the housing 1. A return spring 62 is arranged inside the pressure chamber 61, and a piston rod 6 is slidably connected to the inside of the pressure chamber 61 through the return spring 62. 3. A pressure plate 64 is fixedly connected to the end of the piston rod 63 away from the pressure chamber 61. An oil suction pipe 65 is fixedly connected through the side of the pressure chamber 61, and an oil delivery pipe 66 is fixedly connected through the bottom of the pressure chamber 61. A one-way valve is provided inside both the oil suction pipe 65 and the oil delivery pipe 66. The drive gear 67 is fixedly connected to the surface of the drive shaft 3. The rotating shaft 68 is rotatably connected to the top of the outer shell 1. A driven gear 69 is fixedly connected to the surface of the rotating shaft 68. An eccentric ring 610 is fixedly connected to the top of the rotating shaft 68. A connecting pipe 611 is fixedly connected through the bottom of the outer shell 1. A self-lubricating component 7 is provided at the end of the pressure plate 64 away from the piston rod 63.

[0021] As shown in the figure, the driven shaft 4 is connected to the driving shaft 3 through the planetary gear set 2. The end of the pressure plate 64 away from the piston rod 63 is close to the eccentric ring 610. When the driving shaft 3 rotates, it will drive the driven shaft 4 to rotate through the planetary gear set 2. When the eccentric ring 610 rotates with the rotating shaft 68, it will repeatedly squeeze the pressure plate 64 to move to the right.

[0022] As shown in the figure, the one-way valve inside the oil suction pipe 65 is unidirectionally open to the inside of the pressure chamber 61. The end of the oil suction pipe 65 away from the pressure chamber 61 is connected to the lubricating oil tank 5 through and fixedly connected. When a negative pressure is formed inside the pressure chamber 61, the lubricating oil in the lubricating oil tank 5 will be drawn through the oil suction pipe 65.

[0023] As shown in the figure, the end of the oil supply pipe 66 away from the pressure chamber 61 is connected to the outer shell 1 through and fixedly connected. The one-way valve inside the oil supply pipe 66 is unidirectionally open towards the outer shell 1. When the pressure chamber 61 is squeezed, the lubricating oil inside will be transported to the outer shell 1 through the oil supply pipe 66.

[0024] As shown in the figure, the driving gear 67 meshes with the driven gear 69. The end of the connecting pipe 611 away from the outer casing 1 is connected to the lubricating oil tank 5. When the driving gear 67 rotates, it will drive the driven gear 69 to rotate. Excess lubricating oil in the outer casing 1 can flow back to the lubricating oil tank 5 through the connecting pipe 611.

[0025] As shown in the figure, the self-lubricating component 7 includes an oil reservoir 71, which is located inside the pressure plate 64. Ball bearings 72 are provided on the inner wall of the oil reservoir 71, and an oil injection pipe 73 is connected through and fixedly connected to the top of the oil reservoir 71.

[0026] As shown in the figure, the side of the ball bearing 72 away from the oil storage cavity 71 protrudes from the pressure plate 64, and there are five sets of balls bearing 72. When the eccentric ring 610 is pressed against the pressure plate 64, it will come into contact with the five sets of balls bearing 72.

[0027] A specific application of this embodiment is as follows: An external power source is connected to the drive shaft 3, which drives the drive shaft 3 to rotate. The rotation of the drive shaft 3 drives the driven shaft 4 to rotate through the planetary gear set 2. The characteristics of the planetary gear set 2 can reduce the speed of the driven shaft 4. The rotation of the drive shaft 3 also drives the drive gear 67 to rotate, which in turn drives the driven gear 69 to rotate. The driven gear 69 then drives the rotating shaft 68 to rotate. When the eccentric ring 610 rotates with the rotating shaft 68, it repeatedly squeezes the pressure plate 64 to move to the right. The rightward movement of the pressure plate 64 drives the piston rod 63 to move to the right, compressing the return spring 62. The rightward movement of the piston rod 63 creates pressure in the pressure chamber 61, thereby allowing the lubricating oil inside to be transported through the oil supply pipe 66. The excess lubricating oil in the outer casing 1 can flow back to the lubricating oil tank 5 through the connecting pipe 611. When the eccentric ring 610 rotates away from the pressure plate 64, the return spring 62 rebounds and drives the piston rod 63 and the pressure plate 64 to move to the left to restore their original position. At this time, a negative pressure is formed in the pressure chamber 61, which will draw the lubricating oil in the lubricating oil tank 5 through the oil suction pipe 65, thus forming a circulation flow. While lubricating the planetary gear set 2, it also carries away the heat generated by friction. When the eccentric ring 610 is pressed against the pressure plate 64, it will come into contact with the five sets of balls 72. When the five sets of balls 72 rotate, they will carry out the lubricating oil in the oil storage chamber 71 and coat it onto the eccentric ring 610, reducing the wear between the eccentric ring 610 and the pressure plate 64 and improving the service life of the overall device.
