Note:

The values colored “Red” indicate that the gearbox and the DC motor are running in the same direction, and the other values are in the opposite direction.
When it is desired to reduce the speed further than the gear ratio in the table above, an intermediate speed reducer with a gear ratio of 10 can be installed between the motor and the gearbox.

Tips: Why does the gear motor vibrate?

Armature imbalance. Due to the centrifugal force generated by the unbalanced mass during rotation, a rotational force acts on the bearing, causing vibration of the motor. When the air gap is uneven, the main engine is not tightly fixed, or the rigidity of the base and the end cover is poor, vibration will be aggravated. Therefore, if the rotor is found to be unbalanced during the inspection, it must be rebalanced.
The radial clearance of the bearing is too large, and the outer ring and the end cover loosen together. When assembling, the bearings should be inspected. Bearing and journal, bearing seat must meet the requirements, otherwise it must be sprayed or brushed to deal with the process, to avoid bearing vibration caused by poor. For worn bearings, the frequency of vibration and noise during the operation of the motor is relatively high and it is easy to judge. In this case, bearings should be replaced.
Manufacturing error or deformed operation of the seat, end cover and other important braces. The shape and position error on the fitting surfaces of seat, end cover and other important rotor braces, particular the deformation of important braces (such as seat, end cover) of large and medium motors after long-term operation, make the bearing to produce an interference force, thus leading to the motor vibration.
