Technical Field

[0001] This utility model relates to the field of mechanical transmission equipment technology, and in particular to an energy-saving transmission mechanical device with an eccentric lever on the inner diameter of a planetary gear ring. Background Technology

[0002] Transmission devices include belt drives, chain drives, and gear drives. Belt drives are further divided into flat belt drives and V-belt drives; gear drives are divided into cylindrical gear drives, helical gear drives, rack and pinion drives, and worm gear drives. Existing gear-driven transmission devices, when the input and output power remain constant, exhibit relatively low output torque, resulting in energy waste and low efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an energy-saving transmission mechanical device with an eccentric lever on the inner diameter of a planetary gear ring, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An energy-saving transmission mechanism with an eccentric lever inside a planetary gear ring includes an internal gear ring, a planetary gear mechanism, a sun gear, a lever arm, a flywheel support, a hydraulic jack mechanism, an input shaft, and an output shaft. The planetary gear mechanism includes planetary gears, a lower force-bearing sliding block, and an upper force-bearing sliding block. The planetary gears are symmetrically arranged inside the internal gear ring. One end of each planetary gear meshes with the internal gear ring, and the other end meshes with the sun gear. The sun gear and the internal gear ring are coaxially arranged. The input shaft drives the sun gear and is connected to the output shaft. The internal diameter of the planetary gears is symmetrically arranged with a lever arm. The lower and upper force-bearing sliding blocks are described. The lever arms are symmetrically arranged on both sides of the planetary gear. The lever arms are fixedly connected to the hydraulic jacking mechanism. The hydraulic jacking mechanism serves as a fulcrum, making the radial portion of the input and output shafts the eccentric lever fulcrum and the force-bearing point. The force-bearing point divides the lever arm into a long arm end and a short arm end. The long arm end is away from the sun gear and connected to the lower force-bearing sliding block. The short arm end is close to the sun gear and connected to the upper force-bearing sliding block inside the symmetrical planetary gear. The flywheel bracket is connected to the lever arm via a pin.

[0006] Furthermore, the outer surface of the internal gear ring is provided with an outer shell, an end cap, and a base.

[0007] Furthermore, the long arm end is connected to the lower force-bearing sliding block via a pin.

[0008] Furthermore, the short arm end is connected by a pin to the upper force-bearing sliding block near the sun gear on the inner diameter of another symmetrical planetary gear.

[0009] Furthermore, the hydraulic jacking mechanism is connected to an intelligent automatic control system.

[0010] Furthermore, the total length of the lever arm exceeds the diameter of the planetary gear, and the short arm end extends beyond the central axis of the sun gear.

[0011] Furthermore, the lower force-bearing sliding block is close to the internal gear ring, and the upper force-bearing sliding block is close to the sun gear.

[0012] Furthermore, the center of the flywheel bracket is fixedly connected to the output shaft.

[0013] Furthermore, the two planetary gears are fixedly connected by a planetary gear central shaft support.

[0014] Beneficial effects:

[0015] In this invention, when the sun gear drives the planetary gear meshing internal gear ring for rotation and revolution, the eccentric lever on the inner diameter of the planetary gear ring, connected to the sliding block, generates an energy-saving transmission effect due to the shared force of the lever arm. This significantly reduces the original energy consumption. The energy-saving transmission mechanism with the eccentric lever on the inner diameter of the planetary gear ring in this invention is rationally designed, novel in form, simple in structure, and stable and reliable in operation. It reduces material, processing, and transmission costs, saves input force, and improves transmission efficiency, making it widely applicable to the mechanical transmission of various power machines.

[0023] An energy-saving transmission mechanical device with an eccentric lever on the inner diameter of a planetary gear ring, such as... Figure 1 and Figure 2 As shown, the system includes an internal gear ring 2, a planetary gear mechanism, a sun gear 4, a lever arm 7, a flywheel support 8, a hydraulic jack mechanism 11, an input shaft 5, and an output shaft 6. The planetary gear mechanism includes planetary gears 3, a lower force-bearing sliding block 10, and an upper force-bearing sliding block 14. The planetary gears 3 are symmetrically arranged inside the internal gear ring 2. One end of the planetary gear 3 meshes with the internal gear ring 2, and the other end meshes with the sun gear 4. The sun gear 4 and the internal gear ring 2 are coaxially arranged. The input shaft 5 drives the sun gear 4 and is connected to the output shaft 6. The lower force-bearing sliding blocks 10 are symmetrically arranged inside the planetary gears 3. The lever arm 7 is symmetrically arranged on both sides of the planetary gear 3, along with the upper force-bearing sliding block 14. The lever arm 7 is fixedly connected to the hydraulic jacking mechanism 11, and the hydraulic jacking mechanism 11 serves as a fulcrum, making the radial portion of the shaft diameter of the input shaft 5 and the output shaft 6 the jacking point of the eccentric lever fulcrum. The jacking point divides the lever arm 7 into a long arm end and a short arm end. The long arm end is away from the sun gear 4 and connected to the lower force-bearing sliding block 10, while the short arm end is close to the sun gear 4 and connected to the upper force-bearing sliding block 14 inside the symmetrical planetary gear 3. The flywheel bracket 8 is connected to the lever arm 7 through the pin 13.

[0024] Specifically, in this embodiment, the energy-saving transmission device meshes two planetary gears 3 on the inner diameter of the internal gear ring 2, and the two planetary gears 3 mesh through a central sun gear 4. A lever arm 7 is symmetrically arranged on both sides of the two planetary gears 3. A flywheel support 8 is arranged on the side of the lever arm 7 away from the planetary gear 3, and a planetary gear central shaft support 9 is arranged on the side of the flywheel support 8 away from the planetary gear 3. Therefore, there are two pairs of vertically symmetrical lever arms 7 on both sides of the planetary gear 3. A hydraulic jacking mechanism 11 serves as the eccentric lever fulcrum of the lever arm 7, dividing the lever arm 7 into a long arm end and a short arm end. The long arm end is close to the internal gear ring 2, and the short arm end is close to the sun gear 4. The sun gear 4 rotates through the input shaft 5, thereby driving the planetary gear 3 to rotate. The long arm end is connected to the lower force-bearing sliding block 10, which is close to the internal gear ring 2. The short arm end is connected to the upper force-bearing sliding block 14 inside the symmetrical planetary gear 3, which is close to the sun gear 4. When the sun gear 4 drives the planetary gear 3 to rotate and revolve, the sliding block 10, driven by the lever arm 7 on the inner diameter of the planetary gear 3, rotates together, forming an energy-saving transmission effect of the eccentric lever on the inner diameter of the planetary gear 3. Preferably, the inner gear ring 2 is provided with an outer shell 1, end caps 12 are provided on both sides of the outer shell 1, and base feet 15 are provided at the bottom of the outer shell 1.

[0025] Preferably, the long arm end is connected to the lower force-bearing sliding block 10 via a pin 13, and the short arm end is connected to the upper force-bearing sliding block 14 near the sun gear 4 on the inner diameter of another symmetrical planetary gear 3 via a pin 13.

[0026] Preferably, the hydraulic jacking mechanism 11 and the lubrication oil passage are connected to the intelligent automatic control system to realize the intelligent automation of the device.

[0027] Preferably, the lever arm 7 is located on both sides of the planetary gear 3, and the total length of the lever arm 7 exceeds the total diameter of the planetary gear 3. The short arm end extends beyond the central output shaft 6 and exits the input shaft 5 to connect with the upper sliding block 14 on the inner diameter of the other planetary gear 3.

[0028] Preferably, the lever arm 7 and the lower force-bearing sliding block 10 are connected by two pins 13.

[0029] Preferably, the two planetary gears 3 are fixedly connected by the planetary gear central shaft bracket 9.

[0030] Preferably, the center of the flywheel bracket 8 is fixedly connected to the output shaft 6. The pin 13 connecting the lower force-bearing sliding block 10 near the outer diameter of the flywheel bracket 8 also serves as an output component during revolution.

[0031] It should be noted that the number of planetary gears 3 is not fixed at two symmetrically arranged. One or more can achieve the energy-saving effect of this utility model. Other structures can be adjusted adaptively according to the number of planetary gears.

[0032] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
