How to determine the gap between the motor and the reducer connection?

The gap between the motor and the reducer is determined through installation and adjustment. Generally speaking, in order to ensure the efficiency and stability of transmission, the gap between the motor and the reducer should be minimized to reduce energy loss and vibration.

During the installation process, it is first necessary to ensure that the axis of the motor and reducer are aligned, and that the connection between the motor shaft and the input shaft of the reducer is direct without any offset. Then, use appropriate couplings or flanges to connect the motor to the gearbox.

When adjusting the clearance, the distance between the motor and the reducer can be controlled by adjusting the bolts of the coupling or flange. Normally, the gap should be maintained within the range of 0.05mm to 0.2mm. If the gap is too large, it may cause unstable transmission or generate noise; If the clearance is too small, it may cause excessive bearing load or heat generation.

Before making adjustments, it is also important to check the bearings, seals, and lubrication of the motor and gearbox to ensure their proper functioning. In addition, the appropriate clearance value should be determined based on specific usage requirements and actual situations, referring to the installation manuals or relevant standards of the motor and reducer.
