Description

Technical Field

[0001] This invention relates to the technical field of transmission technology, and more particularly to a power transmission device. Background Technology

[0002] In industrial production, machinery and equipment, and energy conversion, power transmission devices are core components for energy transfer and motion conversion. Their performance directly affects the operating efficiency, adjustment accuracy, and applicability of the equipment. With the increasing demands of modern industry for "high efficiency, flexibility, and miniaturization" in transmission systems, traditional transmission devices have gradually revealed many shortcomings, including: First, low transmission efficiency and high energy loss: Hydraulic and pneumatic transmissions achieve power transmission through fluid pressure, featuring large output force and wide speed range, but they also have a high risk of fluid leakage, easily causing environmental pollution and reducing transmission efficiency; furthermore, the viscous resistance of hydraulic oil leads to energy loss, especially noticeable under low-speed conditions. Second, poor transmission flexibility: Traditional rigid transmission devices such as gear drives and chain drives achieve motion transmission through fixed rigid transmission, with a single transmission direction and only suitable for fixed working conditions.

[0003] Therefore, there is an urgent need to develop a new power transmission device. Summary of the Invention

[0004] The purpose of this invention is to provide a power transmission device that addresses the problems of low transmission efficiency, poor transmission flexibility, and unadjustable power transmission in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power transmission device, comprising a front input section, a middle conversion section, and a rear pressure box; characterized in that the input section is provided with a rotating wheel; the conversion section is provided with a transmission shaft and a transmission disc, the transmission shaft being connected to both a telescopic rod and the transmission disc; and the pressure box being connected to the transmission disc.

[0006] Preferably, the input section is further provided with a rotary motor 1, and a gear A is fixed on the output shaft of the rotary motor, wherein the gear A meshes with a gear B.

[0007] Preferably, gear B is coaxially fixed on a rotating shaft, and the rotating wheel is coaxially fixed at one end of the rotating shaft.

[0008] Preferably, a telescopic rod is fixed to the outer edge of the circumference of the rotating wheel.

[0009] Preferably, one end of the drive shaft is provided with a radial swing groove, and a pin is provided vertically in the swing groove. The telescopic rod is rotatably connected to the pin in the swing groove.

[0010] Preferably, a U-shaped frame is vertically fixed to the outer surface of the other end of the drive shaft, and a swing rod is rotatably connected inside the U-shaped frame.

[0011] Preferably, a U-shaped seat is eccentrically provided on one surface of the transmission disc, and the U-shaped seat is rotatably connected to the swing rod inside.

[0012] Preferably, the pressure box is provided with an initial shaft, an intermediate shaft and an output shaft in sequence and parallel to each other. Each of the three shafts is fixed with a gear C on the same axis inside the pressure box. The three gears C mesh in sequence. The initial shaft is fixed perpendicularly and on the other surface of the transmission disc.

[0013] Compared with the prior art, the present invention has the following technical effects.

[0014] 1. This device adopts a fully mechanical transmission structure (gear meshing, rod connection), avoiding the fluid resistance loss of hydraulic transmission and the slippage problem of belt drive. The input part reduces energy loss during the energy transmission process through the rigid meshing of gear A and gear B, combined with the sliding fit between the telescopic rod and the sleeve.

[0015] 2. The telescopic rod of the input section synchronously achieves axial extension and radial swing as it rotates with the rotating wheel. Combined with the swinging motion of the transmission shaft, it can adapt to angle changes within a certain range. The conversion section is connected to the swing rod through the eccentric U-shaped seat of the transmission plate, which stably converts the swinging motion into rotational motion, providing greater flexibility.

[0016] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-8 A power transmission device includes an input section at the front end, a conversion section in the middle, and a pressure box at the rear end. The original power is input and transmitted through the input section, and then output to the pressure box after corresponding transmission through the conversion section. The input section is provided with a rotating wheel 5, and the rotary motor 1 is fixed on the bracket 22. The conversion section is provided with a transmission shaft 7 and a transmission disc 12. The two ends of the transmission shaft 7 are fixed on the bracket 22 through bearing supports 23. The transmission shaft 7 is also connected to a telescopic rod 6 and the transmission disc 12. The pressure box 14 is connected to the transmission disc 12 and is fixed on the bracket 22.

[0028] The input section also includes a rotary motor 1, with a gear A 2 fixed on its output shaft. Gear A 2 meshes with a gear B 3. Gear B 3 is coaxially fixed on a rotating shaft 4, and both ends of the rotating shaft 4 are fixed to a bracket 22 via bearing supports 23. A rotating wheel 5 is coaxially fixed to one end of the rotating shaft 4. A telescopic rod 6 is fixed to the outer edge of the rotating wheel 5. One end of the transmission shaft 7 has a radially arranged swing groove 8, and a pin 9 is vertically arranged in the swing groove 8. The telescopic rod 6 is rotatably connected to the pin 9 within the swing groove 8. A U-shaped frame 10 is vertically fixed to the outer surface of the other end of the transmission shaft 7, and a swing rod 11 is rotatably connected inside the U-shaped frame 10. A U-shaped seat 13 is eccentrically arranged on one surface of the transmission disc 12, and the swing rod 11 is rotatably connected inside the U-shaped seat 13.

[0029] When the rotary motor 1 starts, gear A 2 drives gear B 3 to rotate. The rotation of gear B 3 synchronously drives the rotating shaft 4 to rotate, and the rotation of the rotating shaft 4 causes the rotating wheel 5 to rotate. The telescopic rod 6 is then driven to rotate. Besides the original power source in this embodiment, which is the rotary motor 1, gear A 2, and gear B 3 to the rotating shaft 4, a hub motor can also be coaxially connected to the center of the end of the rotating wheel 5 that is not connected to the rotating shaft 4. The hub motor directly transmits power to the rotating wheel 5 to make it rotate, and then transmits the power to the rotating shaft 4, replacing the original power source solution. This embodiment does not show this solution, and the structure of the original power source is not limited to these two; users can set it according to their own needs.

[0030] Because the telescopic rod 6 is telescopic and rotatably connected to the pin 9 within the swing groove 8, the multi-faceted cooperation allows the telescopic rod 6 to extend and retract simultaneously with the rotation driven by the rotating wheel 5. This causes the telescopic rod 6 to drive the transmission shaft 7 to swing around its own central axis. The swinging of the transmission shaft 7, connected by the U-shaped frame 10, causes the swing rod 11 to swing, and connected by the U-shaped seat 13, causes the transmission disc 12 to rotate. The pressure box 14 is provided with an initial shaft 15, an intermediate shaft 16, and an output shaft 17 arranged sequentially and parallel to each other. Both ends of the three shafts are fixed to the bracket 22 by bearing supports 23, and each shaft is coaxially fixed with a gear C 18 inside the pressure box 14. The three gears C 18 mesh sequentially. The initial shaft 15 is vertically and coaxially fixed to the other surface of the transmission disc 12. Power is transmitted from the rotating disc 12 to the initial shaft 15 and then into the pressure box 14, where it continues to be transmitted. Within the pressure box 14, the power passes sequentially through the initial shaft 15, gear C 18, and output shaft 17.

[0031] The bracket 22 mentioned in this embodiment is used to raise the relevant parts to a suitable height, and the bearing support 23 is used to firmly connect the shaft components. Users can choose to install according to the actual situation.

[0032] Working process: After the rotary motor 1 starts, its output shaft drives gear A 2 to rotate. Gear A 2 meshes with gear B 3, driving the rotating shaft 4, which is coaxial with gear B 3, to rotate. One end of the rotating shaft 4 is fixed with a rotating wheel 5, which rotates synchronously with the rotating shaft 4. The edge of the rotating wheel 5 drives the telescopic rod 6, causing the telescopic rod 6 to axially extend and retract and radially swing while moving in a circular motion with the rotating wheel 5. The other end of the telescopic rod 6 is connected to the swing groove 8 of the transmission shaft 7 through a pin 9. Its extension, retraction, and swinging cause the transmission shaft 7 to swing back and forth around its own axis. The U-shaped frame 10 at the other end of the transmission shaft 7 drives the swing rod 11 to swing. The swing rod 11 converts the swinging motion into the continuous rotational motion of the transmission disk 12 through the eccentric U-shaped seat 13 on the surface of the transmission disk 12. The rotation of the transmission disk 12 drives the coaxially fixed initial shaft 15 to rotate. The gear C18 on the initial shaft 15 meshes with the gear C18 on the intermediate shaft 16, driving the intermediate shaft 16 to rotate. The gear C18 on the intermediate shaft 16 then meshes with the gear C18 on the output shaft 17, realizing the power transmission to the output shaft 17.
