Flexible Driveline Coupling special winding machine
Flexible Driveline Coupling special winding machine
The
automobile drive shaft is the part connecting the gearbox and the drive axle.
It is a high speed rotating body, and the drive shaft connecting disk is the
part balancing the action of the drive shaft.
The structure of the connecting disk of the drive shaft is shown in the figure below:
It transfers the torque of the engine through the drive shaft to the executing parts.
In this process of transferring torque, the role of the flexible coupling is very important, and the flexible coupling for vehicles is a flexible rubber that can be twisted. It is a very important part of the vehicle transmission system, this flexible coupling is mainly used for rear-drive and all-wheel-drive models, it is used to transfer torque from the gearbox to the executive parts. Because it not only absorbs the impact force, reduces the interference of the transmission system, but also improves the vibration caused by the wrong Angle. Because when our vehicle is driving, the wrong Angle will cause a vibration and noise of the vehicle. This will actually have a relatively large negative impact on our safety and comfort.
And this new type of flexible coupling, it can absorb the impact force, but also can reduce the vibration caused by the wrong Angle. This is mainly because of the specially designed fiber winding in the middle of this coupling. This fiber material is made of high strength fiber silk. However, to develop a flexible coupling winding machine, the main process difficulty is not the winding strength of the fiber. Because of the winding strength of the fiber, it can be improved by increasing the number of fibers. The main difficulty of the process is the balance of the tension of multiple fiber windings.
In terms of the balance of tension between the windings. He will require that the structure of our flexible couplings should be technological, and that the winding process should be taken into account, which can be achieved by automated technology. The process requires that our fibers be wound as neatly as possible. The characteristic of fiber is that under different tension conditions, its cross-section shape after stretching is inconsistent. Then there's tension control. Under a certain tension control of the winding, after the vulcanization of the post-process, there will still be a relatively large pre-loading force. The unbalanced early warning force between the fiber pack and the fiber pack will lead to the dynamic imbalance of the rotation axis in the case of high-speed rotation, so it will aggravate the vibration during the vehicle driving.
This kind of flexible coupling has been serialized in foreign countries. In some brands of bearing manufacturers, such as SKF have been relatively mature. He not only in the rear drive and four-wheel drive intermediate application more. It can also be applied to the connection of internal combustion engine oil pump, compressor and generator. Its characteristics are highly reliable. The connection between the diesel engine and the hydraulic pump in the middle of the shovel often adopts this structure. According to statistics, more than 60% of the world's shovel are using this shaft, so its market potential and economic value is very large.As a professional winding solution provider, we are not afraid when facing these difficulties in the process, but work together with customers to understand and digest the process difficulties of the product.Step by step, through repeated research and testing. These technical problems were successfully solved. And we do it from the beginning, so that our customers can be competitive in their market.
Existing
shaft connection plate is made up of rubber vulcanization six sets of steel,
its structural strength mainly provided by the rubber, in order to increase the
structural strength, the manufacturer will before die casting vulcanized
rubber, between the six sets of steel nylon line, its technology and processing
technology is very similar to synchronous belt, between the six sets of steel
round the multi-layer nylon thread, die-casting vulcanized rubber, It's a good
reinforcement. Such as Mercedes-Benz, Ford have adopted this process.
But
after a long time of use, the drive shaft connecting disk or due to
deformation, and lead to the installation of the shaft sleeve on the drive
shaft connecting disk loosening and instability, therefore, manufacturers need
to do not change the existing mature structure, further improve the structural
strength and balance of the drive shaft connecting disk.
Association, winding machine and to improve the product performance has a persistent pursuit of manufacturers, the brand drive shaft connecting plate on the market for the disassembly analysis, through unremitting efforts, found the increase in space - six nylon line between steel bushing, though the quantity is more, but because the winding is not neat, before vulcanization is mess around, collapse like now. The ideal winding situation is that each nylon wire is neatly arranged and the tension is even, as shown below:
After
REPEATED DESIGN and verification, we have developed this SPECIAL equipment, the
drive shaft connecting coil wire machine, which can wind relatively neat nylon
wire in the closed slot, and can also wind neat nylon wire in the trapezoidal
arrangement in the open position.

Precision winding machine
Precision winding machine For general winding machines, including CNC and automatic winding machines, only the set number of turns of enameled wire is required to be wound, and the appearance is roughly flat, but there are some special high-demand occasions , It is required that the arrangement of enameled wires must be neat without a random winding.
This kind of coil has several advantages. First, the consistency of inductance is very high. Second, the enameled wire occupies less space, and the enameled wire can reach the ideal neat arrangement. Third, the energy density is high. Fourth, the high temperature resistance performance is better. , The enameled wires are in line contact, and in the case of random winding, the superimposition between the wires will have a little contact, and it is easy to break down under high temperature and high pressure.
In order to achieve a stable and neat arrangement, in addition to the requirements for enameled wires, compared with general coil winding machines, high requirements are put forward for the electronic control, mechanism design and manufacturing accuracy of structural parts of the fine winding machine.
R-type transformer winding machine
The cross section of an R-type transformer is like the letter R, so it is called an R-type transformer. The application of R-type transformers in high-power electrical appliances can reduce inrush current. R-type transformers are one of the dry-type transformers. The iron core is made of continuous high-quality oriented cold-rolled silicon steel strip from thin to thick, and then from thick to thin. The final cross-section is close to a circle, and the shape is an uncut closed rectangle, and then passes through a special R-shaped transformer The winding machine winds the coarse secondary on its PBT skeleton. Therefore, the transformer thus manufactured has no noise, low magnetic leakage, low no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of the coil copper wire wound by the R-type transformer winding machine short, so , Low internal resistance, low copper consumption, low temperature rise, low over-carrier motion, and better explosive force than toroidal transformers; in addition, the primary and secondary coils are separately wound with flame-retardant PBT engineering plastic skeletons, thus high electrical strength , Good flame retardancy.
However, the manufacturing process is more complicated. The second is the winding of the coil. Because it is wound in a closed iron core, the PBT is composed of two parts, and then the R-type transformer winding machine drives the PBT skeleton to wind, and the winding accuracy is affected. A certain influence, one is the shape of its iron core, because its expanded shape is a spinning cone, so its mold and material utilization are relatively low.
With the development of R-type transformer winding machines, the reduction of manufacturing costs, and the improvement of quality stability, R-type transformers are being favored by more and more electronics industries with their novel and unique structure and excellent electromagnetic performance. Especially suitable for medical equipment, display equipment, audio equipment, office equipment.

Transformer winding crepe paper | Transformer winding crepe paper | Transformer winding crepe paper
Transformer insulating crepe paper has good mechanical strength, high withstand voltage strength, wrinkles on the surface, and a certain degree of toughness. Moreover, it is easy to cut. After the transformer is wound and formed, it still maintains a certain strength in the oil immersion of the rear tooling. This feature can very well protect the enameled wire of the transformer from being squeezed and broken, that is, it meets the insulation requirements. It also meets the mechanical performance requirements.
Therefore, it is widely used for transformer insulation. Generally used in transformers, but less used in transformers, because the core structure of transformers is annular, because the surface of the insulating crepe paper has wrinkles and friction is large, so the annular wrapping machine is used. Winding is more difficult, so in general, if crepe paper is required for the transformer coil, manual winding is used. We have successfully overcome this problem by improving the details.
