2. High wear resistance: The hardness of gears treated with laser quenching is high, the microstructure is refined, and the wear resistance is superior to the traditional quenching process. Laser quenching causes compressive stress in the tissue and improves the fatigue strength of the gear.
3. Small deformation: The tooth profile deformation of the laser hardened gear is within 0.01mm, no cracks, can maintain the original surface roughness, the gear after laser quenching can be installed directly.
4. Short production cycle: Due to the small deformation caused by laser quenching, it is generally not necessary to grind teeth, which simplifies the production process, increases the production efficiency, and reduces the production cost.
5. To expand the scope of gear selection: You can choose low-cost steel gears, improve the hardness of the tooth surface through laser hardening, and ensure the use requirements.
6. Laser quenching technical parameters:
Gear material: medium carbon steel quenching hardness: HRC45 ~ 50 hardening depth: 0.5 ~ 1.2mm, layer depth controllable. (end)
Non-standard European standard size can be customized according to drawings.
2. Geotextile has good water transmissibility, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass.
3. Geotextile helps to enhance the soil mass' tensile strength and non-deformability and structural stability so as to improve soil mass quality.
4. It can effectively make the concentrated stress diffuse, transfer or decompound, and prevent the soil mass against the destruction of outside force.
5. It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
6. Its mesh is hard to jam by virtue of the compliancy and motility of the reticulation formed by indefinite form fibrous tissue.
7. High water permeability-it can keep good water permeability even in the pressure of soil and water.
8. Corrosion resistant-it is made from polypropylene fiber or terylene or other chemical fiber, featuring resistance to acid and alkali and oxidation, non-corroding, no worm-eaten.
9. Easy construction-low weight, easy operation, simple construction.
1.Special advantages: The gears after hardened by the laser get hardened tooth surface and soft root, while the tooth surface is wear-resistant while guaranteeing the overall mechanical performance of the gear, at the same time more consistent with the use requirements of the gear.
