As for gear grinding, we can achieve a high level of precision, surface finish.
Gring gear Features:
1. High precision: Gear grinding enables the production of gears with extremely high precision and tight tolerances. The grinding process allows precise control of the gear tooth profile, pitch and gear concentricity, resulting in gears with excellent accuracy.
2. Improved surface finish: Grinding gears results in a better surface finish compared to other gear manufacturing methods. The abrasive action of the grinding wheel removes material and creates a smooth surface on the gear teeth, reducing friction and wear.
3. Reduce noise: Grinding gears helps reduce gear noise and vibration. The precise tooth profile and surface finish obtained by grinding minimize gear mesh noise, resulting in quieter gear operation.
4. Increase gear strength: Gear grinding can improve the strength and durability of gears. By removing any surface imperfections or irregularities, grinding improves the gear's load-carrying capacity and fatigue resistance.
Processing features:
1. Shape grinding: Gear grinding usually involves shape grinding, in which the shape of the grinding wheel matches the tooth profile of the gear. Grinding wheels remove material from gear teeth in a controlled manner to achieve the desired tooth shape and size.
2. Continuous grinding: In continuous grinding, the gear and grinding wheel mesh together while rotating in opposite directions. This process is commonly used for cylindrical gears and involves the gradual creation of the entire tooth profile.
3. Reishauer method: The Reishauer method is a method widely used in gear grinding. It uses a threaded grinding wheel to mesh with the gear being ground. When the grinding wheel is fed axially, the gear and grinding wheel rotate to remove material and form the gear tooth profile.
4. Dressing and Dressing: Grinding wheels used for gear grinding require regular dressing and dressing to maintain their shape and cutting efficiency. Dressing involves removing any debris or glazed material from the surface of the grinding wheel, while dressing ensures that the grinding wheel maintains its desired shape and profile.
5. Cooling and Lubrication: During the gear grinding process, cooling and lubrication are critical to preventing overheating and maintaining the integrity of the gear and grinding wheel. Coolant or grinding oil is used to dissipate heat and provide lubrication to ensure the grinding process runs smoothly and efficiently.
6. Quality control: Gear grinding involves strict quality control measures to ensure the accuracy and quality of the gears. Advanced metrology tools, such as gear analyzers and coordinate measuring machines (CMM), are used to check gear dimensions, tooth profile and surface finish.
