View Product Description

1)Descriptions of Internal Gear
The inner ring gear is a ring-shaped gear with teeth on the inner side. When meshing with the outer gear, the two rotate in the same direction (unlike the opposite rotation between the outer gears). This design gives it unique advantages in closed transmission systems.
2)Advantages of Internal Gear

a)Compact structure: The internal gear can be nestedly installed, optimizing the space utilization rate.
b)High transmission efficiency: The friction loss of straight tooth meshing is small, suitable for high-speed transmission.
c)High stability: During meshing, the contact area is large and the impact resistance is good.
d)Easy to integrate: It can be flexibly combined with planetary gears and shaft parts to meet complex transmission requirements.
3)Applications of Internal Gear

a)Industrial robot: Inner ring of the joint reduction mechanism.
b)Aerospace: Actuator transmission system of aircraft control surfaces.
c)Precision instruments: Rotating adjustment mechanism of optical equipment.
d)Electric tools: such as the gearboxes of drills and angle grinders.
