Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transmission shaft processing, in particular to a kinetic energy transmission shaft body and a processing technology integrating pultrusion, braiding, winding, and glue injection. BACKGROUND

[0002] The kinetic energy transmission shaft body is a core component for torque transmission and power output in a mechanical system, and is widely used in the fields of oil exploitation, chemical equipment, new energy vehicles, industrial robots, and high-end manufacturing equipment.

[0003] Traditional kinetic energy transmission shaft bodies are mostly made of metal materials through forging, machining, or welding. However, with the increasing requirements for lightweight, high efficiency, corrosion resistance, and long service life, the metal shaft body material has a large specific gravity, resulting in large rotational inertia and high energy consumption of the entire machine, which cannot meet the urgent needs of lightweight transmission systems in the fields of new energy vehicles and aerospace.

[0004] To overcome the above-mentioned defects, composite kinetic energy transmission shaft bodies have gradually attracted attention in recent years. Composite materials have advantages such as high specific strength, high specific modulus, corrosion resistance, and strong designability, and are particularly suitable for hollow, thin-walled, and high-speed transmission scenarios.

[0005] However, the existing composite shaft body manufacturing process separates the processes of yarn spreading, glue dipping, winding, and post-processing, which has many intermediate transfer links and is prone to introduce pollution, moisture absorption, or uncontrolled tension. It is difficult to achieve continuous and intelligent production of high-performance composite shaft bodies. Moreover, although the winding process can achieve complex mechanical performance design, the interlaminar shear strength is low, and the process strongly depends on the uniformity of resin impregnation. Fiber tapes are prone to residual bubbles and large fluctuations in glue content during the glue dipping process, resulting in uneven performance of the prepreg tape and directly affecting the mechanical consistency and reliability of the final shaft body.

The tiny bubbles in the adhesive are detached from the fiber surface under the action of vibration and collide with each other to form large bubbles. Under the action of buoyancy, they accelerate to rise to the liquid surface and burst, effectively reducing the porosity in the prepreg tape and improving the impregnation quality.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0023] Embodiment one: refer to Figure 1 , the kinetic energy transmission shaft body, the shaft body 10 of the hollow cylindrical structure is made of continuous composite material reinforced thermosetting resin pre-impregnated tape by winding, the composite material includes reinforcing material, matrix material, functional additives and fillers, specifically, the reinforcing material is glass fiber and carbon fiber, the matrix material is epoxy resin, polyurethane resin, the functional agent is ultraviolet absorber, low shrinkage agent, the filler is calcium powder, the inner wall of the shaft body 10 is provided with a plurality of limiting grooves 11, the limiting grooves 11 extend along the shaft body 10, and the length of the limiting grooves 11 is consistent with the length of the shaft body 10, which is used for realizing circumferential positioning and torque transmission with transmission matching parts, such as spline shaft, coupling inner teeth and the like, further, the cross-sectional shape of the limiting groove 11 is any one of rectangle, trapezoid or dovetail shape, preferably dovetail shape, which has self-locking effect and is suitable for high vibration working condition.

[0024] Embodiment two: refer to Figure 2 , the processing technology of the kinetic energy transmission shaft body integrates pultrusion, weaving, winding and glue injection, so as to realize efficient production of high-performance composite material shaft body, the specific steps are as follows: Step one: first, the raw material is arranged into continuous single fiber through the yarn rack, and a plurality of single fibers are stranded and wound into continuous fiber yarn bundle, which is tightly combined and uniformly distributed between the fibers; Step two: the fiber yarn bundle is released through the yarn release rack, expanded horizontally through the yarn spread roller group and flattened into a fiber belt, which aims to eliminate the entanglement between the fibers and ensure that the resin can uniformly cover the surface of the fibers in the subsequent impregnation process; Step three: the continuous fiber belt is sent into the glue dipping device for online impregnation with thermosetting resin to form a pre-impregnated tape; Step four: the pre-impregnated tape is introduced into the preforming mold for preliminary shaping, and the fiber weaving machine is used to weave and coat the outer surface of the tubular core material at the same time, which can increase the interlaminar bonding strength and torsional stiffness of the shaft body; Step five: next, the whole winding completed core mold is sent into the hot pressing curing furnace, and sequentially experiences melting infiltration, pressure densification, cooling crystallization and auxiliary crosslinking reaction to form a solid overall structure; Step Six: Finally, after demolding, equally spaced limiting grooves 11 are machined on the inner wall of the shaft body 10 to improve the connection stability and transmission efficiency between the shaft body and other components.

[0025] This process highly integrates multiple steps, reducing intermediate transfers and contamination. Through pultrusion, weaving, winding, and glue injection, the resulting shaft combines lightweight, high strength, and corrosion resistance.

[0026] Example 3: Refer to Figure 3 - Figure 9 The impregnation device in step three includes a receiving box 20. The receiving box 20 has an inlet 201 and an outlet 202 on both sides. Multiple tension rollers 21 are rotatably installed inside the receiving box 20. The fiber belt is wound around each tension roller 21 in sequence. An extrusion assembly 22 is provided inside the receiving box 20. A heating element 203 is provided at the bottom of the receiving box 20 to heat the adhesive liquid at a constant temperature. The extrusion assembly 22 includes an upper pressure plate 23, a lower pressure part 24 and a support roller 25. The fiber belt is located between the upper pressure plate 23 and the lower pressure part 24.

[0027] The flattened fiber tape enters the receiving box 20 from the tape inlet 201. Guided by the tension roller 21, it forms a multi-segment wetting path in the adhesive and is carried to the space between the upper pressure plate 23 and the lower pressure section 24, where it is moderately squeezed to allow the resin to fully penetrate into the fiber bundle, reducing dry spots and bubbles. The heating element 203 maintains the adhesive at the optimal process temperature, reducing viscosity and improving fluidity and wettability, while preventing the resin from prematurely gelling or cooling and curing. After being extruded to a fixed thickness, the prepreg tape is led out from the tape outlet 202 and directly enters the next station, realizing continuous production.

[0028] Furthermore, the extrusion assembly 22 also includes a support frame 26 fixedly mounted on the receiving box 20. The support frame 26 includes a frame body 261. A pressure frame 262 is rotatably mounted on one end of the frame body 261 near the tape outlet 202. A U-shaped seat 263 is fixedly mounted on the pressure frame 262. The support frame 26 also has two symmetrically arranged guide rods 264 fixedly mounted. A slide rod 265 is slidably mounted between the two guide rods 264. An upper pressure plate 23 is fixedly mounted on the slide rod 265. A motor 27 is fixedly mounted on the frame body 261. An eccentric wheel 28 is rotatably mounted on the U-shaped seat 263. The output end of the motor 27 is connected to the eccentric wheel 28 for transmission. An extension arm 281 is fixedly mounted on the eccentric wheel 28. A push rod 282 is rotatably mounted on the upper pressure plate 23. The extension arm 281 is rotatably connected to the push rod 282.

[0029] Specifically, a first roller 266 is installed on the frame 261, and an eccentric wheel 28 is in contact with the first roller 266.

[0030] After the motor 27 starts, it drives the eccentric wheel 28 to rotate at a constant speed. Since the center of mass of the eccentric wheel 28 is off from the center of rotation, it will generate periodic radial displacement when rotating. The eccentric wheel 28 pushes the push rod 282 through the extension arm 281, converting the rotational motion into the reciprocating swing of the push rod 282, which in turn drives the slide rod 265 to slide up and down along the guide rod 264, so that the upper pressure plate 23 applies periodic dynamic pressure to the fiber belt, effectively eliminating residual air bubbles inside the fiber bundle and promoting the redistribution of resin between the fibers, significantly improving the impregnation uniformity and density of the prepreg. During the rotation cycle of the eccentric wheel 28, since it is always in contact with the first roller 266, the pressure frame 262 will be lifted around the rotation point by force, releasing the pressure of the upper pressure plate 23 on the fiber belt, so that the fiber belt can be intermittently wound by the external winding device.

[0031] Reference Figure 5 - Figure 8 The upper pressure plate 23 includes an upper plate body 231. A first connecting seat 232 is slidably installed on the side of the upper plate body 231 near the fiber belt. An upper extrusion roller 233 is rotatably installed in the first connecting seat 232. A groove 234 is opened in the upper plate body 231. The first connecting seat 232 is slidably installed in the groove 234. A first spring 235 is fixedly connected between the first connecting seat 232 and the top surface of the groove 234.

[0032] The pressing part 24 includes a lower seat 241 mounted on two side support rollers 25. A lower plate 242 is slidably mounted on the lower seat 241. A second connecting seat 243 is fixedly mounted on the lower plate 242. A lower extrusion roller 244 is rotatably mounted on the second connecting seat 243. Limit boxes 30 are fixedly mounted on both sides of the lower plate 242. A horizontal shaft 31 is fixedly mounted inside the limit box 30. An X-shaped hinge 32 is slidably mounted on the horizontal shaft 31. The X-shaped hinge 32 is rotatably connected to the inner wall of the limit box 30. Pins 236 are fixedly mounted on the upper plate 231 at both ends of the upper extrusion roller 233. A second roller 33 adapted to the pins 236 is rotatably mounted on the X-shaped hinge 32. A second spring 34 is sleeved on the horizontal shaft 31. The two ends of the second spring 34 are fixed to the X-shaped hinge 32 and the inner wall of the limit box 30, respectively.

[0033] A tensioning wheel 245 is rotatably mounted inside the lower body 241. A tensioning belt 246 is sleeved on the tensioning wheel 245. The lower plate 242 is fixedly mounted on the tensioning belt 246. A torsion spring is provided between the tensioning wheel 245 and the inner wall of the lower body 241.

[0034] Under the action of the first spring 235, the upper extrusion roller 233 and the lower extrusion roller 244 maintain pre-tight contact and clamp the fiber belt. When the eccentric wheel 28 rotates to the lowest point and contacts the first roller 266, the pressure frame 262 covers the fiber belt. As the eccentric wheel 28 continues to rotate, the extension arm 281 pushes the push rod 282 to push the upper plate 231 to one side to the maximum stroke. The upper extrusion roller 233 on the upper plate 231 presses the upper surface of the fiber belt. At the same time, the pins 236 on both sides of the upper plate 231 are inserted between the two second rollers 33 in the limiting box 30. The two second rollers 33 move away from each other along the horizontal axis 31, and the other ends of the X-type hinge 32 move closer to each other, thereby clamping the lower extrusion roller 244 and keeping the lower extrusion roller 244 in a fixed state. At this time, the lower extrusion roller 244 and the upper extrusion roller 233 cooperate to form a rigid pressing state, applying peak extrusion force to the fiber belt and improving the impregnation density. As the eccentric wheel 28 rotates to its highest point and contacts the first roller 266, the pressure frame 262 rises, and the pin 236 releases the X-shaped hinge 32 and the limit box 30. The limit box 30 resets under the action of the tension belt 246 and the torsion spring, and the X-shaped hinge 32 resets under the tension of the second spring 34, releasing the locking of the lower extrusion roller 244. When the external winding roller winds up the fiber belt, the friction between the lower extrusion roller 244 and the fiber belt is converted into rolling friction, which greatly reduces the running resistance and reduces damage to the fiber surface.

[0035] Reference Figure 9 The container 20 includes an outer layer 204 and an inner layer 205. Notably, the inlet 201 and outlet 202 are located on the outer layer 204. The heating element 203 is installed between the outer layer 204 and the inner layer 205. The tension rollers 21 are installed in the outer layer 204 below the inlet 201 and outlet 202, and on the support frame 26. The inner layer 205 contains only adhesive. A load-bearing rod 40 is installed between the outer layer 204 and the inner layer 205. A special-shaped wheel 211 is fixedly installed on the tension roller 21. A protrusion 206 that contacts the special-shaped wheel 211 is fixedly installed on the inner bottom surface of the inner layer 205. The load-bearing rod 40 includes a rod body 41 and a rod sleeve 42 that can slide relative to each other. A third spring 43 connects the rod body 41 and the rod sleeve 42.

[0036] When the fiber tape is wound up, the tension roller 21 on the support frame 26 rotates accordingly. During the rotation, the shaped wheel 211 periodically hits the contact point of the protrusion 206, forming a regular impact. The inner layer 205 as a whole compresses the third spring 43 under the impact and oscillates slightly along the direction of the load-bearing rod 40. The third spring 43 provides elastic restoring force, so that the inner layer 205 rebounds quickly after each impact, forming forced vibration. The tiny bubbles in the adhesive detach from the fiber surface under the action of vibration and collide with each other to form large bubbles. Under the action of buoyancy, they accelerate to rise to the liquid surface and burst, effectively reducing the porosity in the prepreg tape and improving the impregnation quality.
