📋 Frequently Asked Questions (FAQ)
Q1: What is the advantage of the dual-locking (Keyway + Set Screw) design?
The standard mechanical keyway handles the bulk of the high-torque transmission and prevents rotational slippage under heavy loads or sudden reversals. The M6 set screw provides axial positioning and extra locking security, ensuring zero-backlash and maximum stability for advanced robotics.
Q2: Is this flange coupling fully compatible with RoboMaster wheels?
Yes. The flange features two different bolt circles. The inner Ø45mm pitch circle with 3 × Ø5mm through-holes is perfectly spaced and explicitly engineered to match standard RoboMaster 152mm Mecanum wheels.
Q3: What wheels can be mounted using the Ø47.5mm bolt circle?
The Ø47.5mm pitch circle (3 × Ø5mm through-holes) is universally compatible with standard 100mm and larger omnidirectional wheels, Mecanum wheels, heavy-duty pneumatic tires, and honeycomb wheels commonly used in ROS research platforms and AGVs.
Q4: Does the package include the drive key and set screws?
Each coupling comes with the corresponding M6 tightening set screw included. Please note that the square drive shaft key (parallel key) is not included and needs to be matched according to your motor shaft’s specifications.
