Internal gear is a gear which teeth mesh with a spur gear on the inner side of a cylinder.
Regarding the manufacturing of internal gears, Normal Hobbing cannot be used for Machining due to the special shape. Usually, Internal gears are machined using Hobbing machines.
Usually, Internal gears can be used in conjunction with spur gears of the same module. It must be noted that different combinations of internal gear and spur gear teeth can result in involute interference, hypocycloid interference, and gear to gear interference.
Internal tooth gears are often used in planetary gear mechanisms and gear couplings. The most common planetary gear mechanisms are planetary, sun, and star types. According to its type and the setting changes of input and output shafts, various combinations of transmission ratios and rotation directions can be designed.
The production of straight and helical internal tooth gear and ABS gear rings requires very special professional knowledge.
Our experienced employees, coordinated production processes and materials, as well as special heat treatment processes, are prerequisites for mass production of such precision parts.
We turn, tooth, harden and surface treat gears up to 5 m in diameter. These gears are primarily used in the wind turbine industry, but mining, shipbuilding and cement production also benefit from our expertise in this special area. we also can supply large, top quality cylindrical gears.
