Hand engine (handmade engine,High-tech exports HS code categorization let you go on the road easily!) Bicycles are one of the means of transportation for many people, but sometimes they require faster speed and greater power. Electric bicycles are a good choice, but they may be more expensive. If you want to try DIY mechanical production, handmade bicycle engines are a good choice. This article will introduce how to make a hand engine to improve the speed and power of the bicycle. First of all, you need to prepare some materials and tools, including steel plates, clutches, gears, rivets, screws, hand crank motors, motor wires, batteries and some conventional tools, such as pliers, screwdrivers and drills. The choice of materials and tools depends on your design and skill level, but pay attention to the quality and applicability of the materials when choosing. Secondly, you need to draw a design drawing, including the shape and size of the engine, the gear transmission ratio, the design and position of the clutch, etc.You can use CAD software to draw design drawings and redesign them as needed. The design drawing needs to detail the size and position of each part to ensure that the final assembled engine can operate normally. Next, you need to make parts according to the design drawings, including clutches, gears, aluminum end panels and high-voltage wires. The production of these parts requires certain skills and machines, such as drilling machines, milling machines, lathes and machining centers. Since this requires certain experience and skills, it is recommended that beginners do not try more complex techniques. Please determine the difficulty of production according to your own actual situation. Then, you need to assemble these parts, and you need to be patient and careful during the production process. First, install the gears and clutches on the rotor shaft, and adjust their position, height and traction.Then fix the aluminum end panel to the base, and then install the rotor shaft and motor wire correctly on the base. After completion, place the engine in the appropriate position on the bicycle and connect the appropriate wire and battery. Finally, you need to carefully check the position and function of each part to ensure that the engine can run normally and conduct a formal test. You can observe the rotation of the gear through the hand crank rotor and test the performance of the engine on the bicycle through the power supply. If the engine can provide greater power and speed when walking on a flat road, then you can use it as your own means of transportation. In short, making a bicycle engine requires skill and patience, but it can provide higher speed and power for your bicycle, making it easy for you to ride on the road. I hope this article can help you better understand the production process and operation details of this engine.
