Grinded Gear Shaft

Grinded Gear Shaft

Characteristics

• High Precision: Through precise grinding, the tooth profile accuracy can reach IT6 - IT3 level, and the tooth pitch cumulative error can be controlled within 0.02mm, which can meet the requirements of high-precision transmission.

• Good Surface Quality: The surface roughness can reach Ra0.4 - 0.2μm, which reduces friction loss, improves transmission efficiency, and can reach more than 98%.

• High Wear Resistance: The grinding process can enhance the surface hardness of the gear shaft. Combined with heat treatment processes such as carburizing and quenching or nitriding, the fatigue resistance can be increased by 30%, and adhesive wear can be suppressed.

Manufacturing Process

• Pre - grinding Inspection: Before grinding, the gear shaft is thoroughly inspected to check for defects such as cracks, dimensional deviations, and surface imperfections.

• Setup and Alignment: The gear shaft is accurately installed and aligned on the grinding machine to ensure that the grinding process can be carried out according to the specified requirements.

• Rough Grinding: Remove most of the excess material to form a basic shape close to the final size and prepare for the final grinding.

• Final Grinding: Use a specific grinding wheel to perform fine grinding on the tooth surface and other parts of the gear shaft to achieve the required dimensions, surface finish, and tooth profile accuracy.

• Inspection and Quality Control: After grinding, the gear shaft is inspected for dimensions, shape tolerance, surface roughness, etc. to ensure that it meets the design specifications.

Grinding Techniques

• Profile Grinding: Grind the gear shaft to obtain the required tooth profile to ensure accurate meshing and smooth operation of the gear.

• Worm Grinding: Use a worm - shaped grinding wheel to grind the gear shaft, which can obtain a more accurate tooth profile.

• Threaded Wheel Grinding: Use a threaded grinding wheel to grind the gear shaft, which is suitable for gear shafts with special thread - shaped tooth profiles.

Application Fields

• Automotive Industry: It is used in the manufacture of gears in transmissions, engines, and drivetrains to ensure the reliable operation of the vehicle's power transmission system.

• Industrial Machinery: Such as pumps, compressors, and machine tools, which require accurately ground gear shafts to ensure smooth operation and high - efficiency power transmission.

• Aerospace Sector: Used to manufacture high - precision gears for aircraft engines, landing gears, and other key components, which can meet the strict requirements of the aerospace field for component performance.
