What are the advantages of shaft core? Come and collect!
The double-axis high-speed guide rail is composed of a high-speed motion slider composed of an aluminum alloy body and a steel guide shaft core embedded in it, and a box-type sliding unit composed of a shaft core and a roller. It has low cost, high speed, and low noise. It is widely used in the machinery industry. High-speed guide rail, double-axis core high-speed guide rail, roller slider, silent slider, aluminum alloy slider, high-speed slider High-speed guide rail is a South Korea product. Compared with ordinary ball guide rail, its working speed is 10 m/min, and It can be done longer.
The shaft core structure is different, the force is different, the gear matching is different, and the installation method is also different. The two general combinations are sliding and interference, such as sliding gears. Align the shaft with the position and angle, and then push it in gently. When the interference is small, you can use a heavy hammer to knock the shaft end to drive the shaft. Cover the shaft end with other objects to avoid damage to the shaft end. The amount of interference is large, and the shaft can be pressed in with a hydraulic press. If there is no hydraulic press, you can quickly make a temporary tool with some steel plates and large bolts on hand, and use the power of the thread to pull or push the shaft into the gear. Excessive heating methods (eddy current heating, etc.) can be used. After the gear is heated and expanded, the shaft can be easily pushed in, or the shaft can be cooled and contracted in turn, and then pushed in.
Either way, before assembling the shaft core, remove burrs, dirt and apply lubricating oil. A standard shaft core includes a connecting section, a rotating section and a fixed section. One end of the rotating section is connected with the connecting section, and the other end is connected with the fixed section. The fixed end is provided with a through hole, a baffle is provided in the stable inner cavity, one end of the rotating shaft is fixedly connected with the middle side wall of the connecting rod, and the baffle is provided with a spring, the spring passes through the through hole and is connected with the clamping block. One side of the clamping block is provided with a groove. The structure of the present invention is simple. By adding a connecting rod and a clamping block, it is convenient to clamp and stabilize other parts, and prevent the parts from rotating when the core shaft is rotated. The spring facilitates the movement of the clamping block, so that the fixed section can easily pass through the through the through hole of the part, which improves the installation efficiency and maintenance efficiency of the part, easy to install, use and replace the mandrel.
What are the advantages of precision shaft core in use? Here to introduce you.
1. High strength, can withstand load for a long time, wear-resistant and self-lubricating, provide better working performance than bronze cast iron carbon steel and phenolic laminate in oil-free (or oil-free) lubrication applications, reduce consumption and save energy;
2. Noise absorption and shock absorption. The modulus of MC nylon is much smaller than that of metal, which attenuates vibration greatly, and provides a better practical way to prevent noise than metal;
3. Simplify the maintenance of the machine, save manpower, have excellent processing performance, improve labor productivity, low mc coefficient, which provides the possibility for its wide application in friction parts;
4. Good resilience, able to bend without deformation, while maintaining toughness, resistance to repeated impacts, compared with metal, MC nylon has low hardness and does not damage wear parts;
5. High chemical stability, alkali resistance, alcohol, ether, hydrocarbon, weak acid, lubricating oil, detergent, water (sea water), and odorless, tasteless, no rust, for its widely used in alkali corrosion resistance, environmental health, food, textile printing and dyeing and other mechanical parts provide excellent conditions. Different from the role of the liner in industrial use, the liner has the role of lifting the grinding medium and protecting the grinding barrel.
