How to replace the motor bearing How to disassemble the motor bearing of the electric vehicle

Pull out the pair of wheels with a pull tool, remove the outer oil seal of the motor, and remove the end cover of the motor.

Be careful not to hurt the stator coil of the motor, and use the pull tool to remove the bearing.

Clean the inner and outer oil seals.

Install the inner oil seal, install the bearing, grease the bearing and the inner oil seal, install the motor end cover, at this time, pay attention to use a thin copper wire to penetrate the screw hole of the inner oil seal from the motor end cover hole, in case the outer oil seal and the inner oil seal screws do not match.

Tighten the end cover of the motor, install the outer oil seal, and tighten it with uniform force and install it on the right wheel.

Disc motor, there should be no resistance.

1. See if there is a circlip on the outside of the bearing, and remove it if there is.

Second, the use of pullers is to pull out the old bearings with a puller. Or lay the rotor flat and hit the jacket of the old bearing directly and smash it out.

3. Hot charging: When the new bearing is heated with a bearing heater or electric furnace to a particularly hot temperature (to avoid smoke), it is lifted and pushed directly to the bearing position.

Cold assembly: the bearing is sleeved on the shaft with an iron rod or round steel against the inner sleeve and smashed into it (the force should be uniform), and the small motor can find a steel pipe with the same diameter as the inner sleeve to cushion and smash it into place.

The new bearing should avoid dust and dust particles.

Remove the hood, remove the blade, pry open the end cover, drag out the rotor, and pull down the bearing with the pull code.

The motor bearing of the electric vehicle is installed from the inside of the click shell, and the motor shell needs to be completely disassembled to remove the motor bearing, and the specific operation steps are as follows:

1. Place the wheels flat on the ground.

2. Remove the fixing screws around the motor housing.

3. Spread a soft cloth on the ground.

4. Hit the wheel axle against the soft cloth on the ground and open the cover.

5. Hammer the bearing of the inner hole of the cover.

6. At this time, the bearing distance is removed.

How to disassemble the internal and external separation of the motor bearing of the electric vehicle? Use a napkin to make it easy for you to remove.

First of all, remove the tire from the frame, use a tool to open the side without motor wire, take out the rotor and use the puller to take out the bearing, replace it with the newly bought bearing, press it back into the rotor shaft, cover the cover, turn on the power supply and use it to see if it can be rotated. If it can be turned, simply install the tire back into the frame.

The replacement bearing type is: 6004-2RS (two sets) or 6004-2RZ (two sets).

After the motor is removed, the motor wheel is removed with two crowbars symmetrically, if it is cast iron, the groove pulley should be pried next to the motor output shaft, otherwise the pulley will be broken, and the puller should be used as much as possible.

After removing the pulley, replace it with a tighter key or punch a hole taper buckle at the shaft end of the motor shaft, and measure the length and size according to the ideal position of the grooved pulley, and turn a sleeve and a shaft end gland.

Then ensure that the motor wheel will not move back and forth left and right, and tighten the shaft end gland with screws (plus spring washers). Once removed, it can be replaced in the same way.

Summary. Hello, dear, the motor shaft is generally one of the important parts of the motor, if there is wear or damage, etc., it can be replaced. However, the replacement of motor shafts requires a certain amount of professional knowledge and skills, as well as special tools and equipment to operate.

Therefore, in general, it needs to be replaced by professional motor maintenance personnel or maintenance manufacturers. When replacing the motor shaft, the following points should also be noted:1

Confirm the model and specification of the motor shaft to ensure that the replaced shaft matches the original shaft; 2.When replacing the motor shaft, it is also necessary to check whether the other parts of the motor are worn or aged, and if necessary, they should be replaced or repaired; 3.After the motor shaft is replaced, the motor needs to be debugged and tested to ensure that the running status and performance of the motor meet the requirements and avoid other problems.

It should be noted that for some special motors, such as high-speed motors, high-power motors, etc., replacing the motor shaft needs to be more cautious and professional, and should be operated by motor maintenance professionals with relevant experience and qualifications.

However, the replacement of motor shafts requires a certain amount of professional knowledge and skills, as well as special tools and equipment to operate. Therefore, in general, it needs to be replaced by professional motor maintenance personnel or the first repair manufacturer.

When replacing the motor shaft, the following points should also be noted:1Confirm the model and specification of the motor shaft to ensure that the replaced shaft matches the original shaft; 2.

When replacing the motor shaft, it is also necessary to check whether the other parts of the motor are worn or aged, and if necessary, they should be replaced or repaired; 3.After the motor shaft is replaced, the motor needs to be debugged and tested to ensure that the running status and performance of the motor meet the requirements and avoid other problems.

These two can be exchanged.

What about people. Confirm the model and specification of the motor shaft to ensure that the replaced shaft matches the original shaft or the shaft that comes to block the branch; When replacing the motor shaft in a simpler way, it is also necessary to check whether the other parts of the motor are worn or aged, and if necessary, they should be replaced or repaired.
