What is the calculation formula for aligning the coupling center of motor and reducer?

Motor front foot quantity: divide the distance from the wheelset end face to the front foot by the wheelset diameter and multiply it by half of the axial deviation value+radial deviation value?

Motor rear foot quantity: divide the distance from the rear foot of the counter wheel to the end face by the diameter of the counter wheel, and then multiply it by half of the axial deviation value+radial deviation value.

However, please note that it is necessary to correctly judge the height of the mouth and the motor, which is the key to ensure the accuracy of the centering calculation results!

Independent components consisting of gear transmission, worm transmission and gear-worm transmission enclosed in a rigid housing are usually used as reduction transmission devices between the prime mover and the working machine. It plays the role of matching rotational speed and transmitting torque between the prime mover and the working machine or actuator.

Extended data:

After running for 200~300 hours, the oil should be changed for the first time, and the quality of the oil should be checked regularly in future use, and the oil mixed with impurities or deterioration should be replaced in time.

The reducer runs continuously for a long time. Replace the new oil after running for 5000 hours or once a year, and replace the new oil before running again. The reducer should be added with the same brand of oil as the original factory, and different brands of oil should not be mixed. Oils of the same brand but different viscosities are allowed to be mixed.

When changing oil, wait until the reducer cools down, and there is no danger of combustion, but it is still necessary to keep warm, because after complete cooling, the viscosity of oil increases, and it is difficult to discharge oil. Note: cut off the power supply of transmission equipment to prevent accidental power-on.

The working principle of DC generator is to use the commutation function of brush to change the AC electromotive force induced in armature coil into DC electromotive force when it is led out from the end of brush through commutator.

The direction of induced electromotive force is determined according to the right-hand rule (the magnetic induction line points to the palm, the thumb points to the direction of conductor movement, and the other four fingers point to the direction of induced electromotive force in the conductor).
