Metal Internal Gears

The metal internal gears made in Feida machinery factory are cylindrical gears with spur or helical teeth cut on the inner surface ,meshing with extermal gears.They are typically used in planetary systems and feature compact design,smooth operation,and high load capacity.The core parameters of these gears are module,number of teeth, pressure angle,helix angle(for helical internal gears),center distance,face width, and addendum modification coefficient.

In terms of materials,their gear body and tooth surface have different material requirements,that is ,the gear body must be tough and impact-resistant, while the tooth surface must be hard and wear-resistant.

With over 30 years of development,we can provide end-to-end services from raw material procurement to manufacturing and packaging, ensuring efficiency and precision in every product.These service are as follows:

Application

In addition to compact design,smooth operation,load high load capacity,metal Internal gears also have advantages of high strength,excellent wear resistance etc.They are widly used in applications,including planetary gear systems,heavy machinery,robotics,aerospace,industrial gearboes,etc.
