Basic Structural Components
Two bushings with external teeth: connected to the input and output shafts respectively via splines.
Two outer sleeves with internal teeth and flanges: connected as one unit by bolts.
Internal and External Gear Meshing: The gears on the outer bushings mesh with the internal teeth on the outer sleeves, transmitting torque and motion.
Core Working Principle
Power Transmission: Input shaft rotates → Outer bushings rotate accordingly → Through internal and external gear meshing → Drives the outer sleeves → Output shaft rotates synchronously.
Displacement Compensation Mechanism: The tips of the external teeth are machined into spherical surfaces, and tooth flank clearance and tip clearance are reserved during meshing.
These structures allow radial, axial, or angular displacement of the two shafts during operation, thus accommodating installation errors or deformation during operation.
High-precision synchronization: Gear meshing ensures an average transmission ratio of 1 between the input and output shafts, achieving accurate synchronization suitable for high-speed, heavy-load applications (such as aircraft engines, gas turbines, and heavy machinery).
Lubrication and reliability: A lubrication system is typically required to reduce tooth surface wear, extend service life, and support high-speed operation (up to 3500 r/min).
