Children's mountain bike dental disk customization needs to pay attention to the following aspects:
First, size adaptation
1. According to the child's age, height and riding ability, the diameter and number of teeth should be accurately determined. Generally, younger children are suitable for smaller diameter and fewer teeth to adapt to their relatively weak leg strength and riding speed needs. For example, for children aged 6-8 years, a disk with a diameter of 120-140 mm and a tooth count of 24-32 teeth may be more appropriate.
2. Ensure that the tooth disk and the bicycle frame and crank components can be perfectly installed, and there is no problem that the installation gap is too large or too small, so as not to affect the stability and safety of the ride.
Second, material selection
1. Choose lightweight and strong materials, such as aluminum alloy. The aluminum alloy material can not only ensure that the dental disk has enough strength to withstand the force of children's riding, but also reduce the weight of the vehicle, which is easy for children to control. For example, 6061 aluminum alloy is a commonly used bicycle parts material with good mechanical properties and corrosion resistance.
2. Consider the durability of the material, which should be able to withstand wear and collision during daily riding. Materials with special surface treatment can be selected to increase their wear resistance and corrosion resistance and extend the service life of the dental disc.
3. Design characteristics
1. The shape design of the dental disc should be as simple and smooth as possible, and sharp corners should be avoided to prevent accidental injury to children during riding. For example, the use of rounded edge design and integrated structure to reduce potential safety hazards.
2. According to children's preferences and personalities, some interesting patterns or colors can be designed on the surface of the dental disk to increase the attractiveness of the bicycle and children's riding interest.
Fourth, performance optimization
1. Ensure smooth rotation of the dental disk and accurate coordination with the chain. Through high-precision processing technology, the tooth shape of the tooth disk and the roller of the chain can be perfectly matched, reducing the energy loss and noise during riding.
2. Consider the gear shift compatibility of the gear disc. If the child's bicycle is equipped with a gear shift system, the gear disc needs to be coordinated with other components of the gear shift system to achieve smooth gear shift operation.
5. Quality inspection
1. After the customization is completed, strict quality testing should be carried out on the dental disc. Including the strength test of the material, you can carry out tensile, compression and other tests on the dental disc material through the professional material testing machine to ensure that it meets the relevant quality standards.
2. Simulate the actual riding conditions, conduct a long-term operation test on the dental disc, check its performance under different loads and speeds, and whether there are deformation, loosening and other problems.
