Lapped bevel gears production process

The production process of lapped bevel gears involves several steps to ensure accuracy and quality. Here is a general overview of the process:

Design: The first step is to design the bevel gears according to the specific requirements of the application. This includes determining the tooth profile, diameter, pitch, and other dimensions.

Material selection: High-quality steel or alloy materials are typically used for lapped bevel gears due to their strength and durability.

Forging：Metal is heated and shaped using compressive forces to create the desired gear shape.

Lathe turning: rough turning: material removal and shaping. Finish turning: achieve the final dimensions and surface finish of the workpiece.

Milling: The gear blanks are cut from the selected material using CNC machining. This involves removing excess material while maintaining the desired shape and dimensions.

Heat treatment: Then heat-treated to enhance their strength and hardness. The specific heat treatment process may vary depending on the material used.

OD/ID grinding: Offers advantages in terms of precision, versatility, surface finish, and cost-effectiveness

Lapping: Lapping is a crucial step in the production of bevel gears. It involves rubbing the gear teeth against a rotating lapping tool, typically made of a soft material like bronze or cast iron. The lapping process helps in achieving tight tolerances, smooth surfaces, and proper tooth contact patterns.

Cleaning process: The bevel gears may undergo finishing processes such as deburring, cleaning, and surface treatments to enhance their appearance and protect against corrosion

Inspection: After lapping, the gears undergo a thorough inspection to check for any defects or deviations from the required specifications. This may involve dimension test, chemical test, accuracy test, meshing test ect.

Marking: Part number lasered according to customer’s request for easier product identification.

Packing and warehousing:

It’s important to note that the above steps provide a general overview of the production process for lapped bevel gears. The exact techniques and processes may vary depending on the specific manufacturer and application requirements.
