Why is there no oil filling hole in the bearing of the motor?

Ordinary motor bearings are deep groove ball bearings with sealing rings.

This kind of bearing has been filled with grease after the assembly, no need to re-add grease, can fully meet the requirements of use, if the grease is gone, it is recommended to replace the new bearing of the same model, you just go to add grease, it will not take long, a new set of new is not expensive, the market is also easy to buy, the general hardware store or bearing store are sold. The butter you generally add has a high content of impurities, and after mixing with the original original grease, adding it to the new bearing will increase the noise of the bearing and seriously reduce the service life of the bearing.

The motor bearing with a refueling nozzle is replenished with butter about once every six months, but many motors are not equipped with a refueling nozzle at all, does this kind of motor still need to be refueled regularly? Every time you refuel, you have to remove the front and rear end covers of the motor, which is too troublesome.

Most of the motor bearings are rolling bearings, and there are various forms of balls between the inner and outer pads. Beaded, cylindrical, wedge-shaped columns, single or double row arrangement. Roll to reduce friction.

The sliding bearing is separated by the oil film between the inner and outer pads and has a strong bearing capacity, which is divided into hydrostatic oil film bearing, dynamic oil film bearing and dynamic and static oil film bearing, which belongs to thin oil lubrication. It is necessary to keep oil available at all times, so there are oil filling holes to add new oil.

The motor oil filler hole is directly above, the oil drain port is at the bottom, open the motor or gearbox need to put the internal oil nucleus clean through the oil drain hole, and if you change the oil regularly, you must also clean the oil from the oil drain hole to add clean new oil.

The best way to fill a motor is to use an oil gun. It is best not to directly ignite the oil in the motor, because there is a change in the balance rent, which may cause the powder worn by the carbon brush to be everywhere inside the motor, which is easy to break the circuit. If you want to oil the motor, it is best to remove some oil, point a drop of oil from the top and then turn it around, and turn the head down, so that the dirty things can be cleaned out.

Then rub your fingers into a thin line, dip the oil in the motor clean, and the other end is also oiled in the same way, cut the air and do not point directly into the motor, remember to turn it every time you turn it over after oiling. When it is found that there is a loud sound when the motor rotates during use, this method can extend the service life of the motor. <>

Hello dear, thank you for your patience, the location of the motor oil filling hole depends on different types of motors and equipment. On some motors, the filler holes may be located at the end or side of the motor, while on others they may be on the top or bottom of the motor. Some motors may have multiple filler holes for better lubrication of the various parts of the motor.

If you want to find the exact location of the motor oil filler hole, it is best to check the user manual of the relevant device or contact the manufacturer for more information. In addition, it is important to regularly check the lubrication condition of the motor to ensure the proper functioning of the equipment. Note that it is also crucial to use the right lubricant, as different motors may require the use of different types of lubricant slag.

Lubrication and maintenance of the motor is one of the important guarantees for the service life of the motor, and regular inspection and maintenance of the lubrication of the motor can prolong the service life of the motor, reduce the cost of maintenance and replacement, and improve the efficiency of production and production. Therefore, it is very important to know the location of the motor oil filling hole and the correct lubrication method. Gestures.

There are oil holes in the bearings in the motor, but the reason why the oil can't be punched in is that the oil holes are blocked by the steel balls inside the bearings. SunThai Bearing Technical Services.

Don't know how big your motor is? Is it explosion-proof or ordinary?

3. It may also be that there are holes in the inner cover, but the position of the inner cover is not correct, so that the hole of the inner cover and the hole of the large cover are misplaced and cannot be passed.

4. The oil injection hole may be blocked.

There are only a few cases.

If you really can't add it, you'll have to turn on the motor and take a look.

Yes is an oil seal! Can only be opened.

The oil duct is a dead end and is not connected to the oil cavity. I've been in this situation. Let's open it and take a look.

Summary. Hello, if the motor does not have oil injection holes, then you need to add lubricating oil to the bearing regularly. The bearing is generally located inside the motor and needs to be disassembled to reach the motor housing.

It is recommended that you find the instruction manual of the motor or consult a professional technician to ensure that the lubricating oil is added correctly and that damage to the motor is avoided.

Please ask the teacher I send the motor**, this motor does not have oil injection holes, you need to add lubricating oil to the bearing regularly, right? Where is the location?

Hello, if the motor does not have an oil injection hole, you need to add lubricating oil to the bearing regularly. The shaft is generally located inside the motor, and the motor shell needs to be disassembled to reach it. It is recommended that you find the instruction manual of the motor or consult a professional technician to ensure that the lubricating oil is added correctly and that damage to the motor is avoided.

Generally, a little bit is applied to reduce vibration. There are also some motor manufacturers who do not paint, and this does not affect the use of high grip. If you install it yourself, it is better to apply a little bit, because there is a gap in the bearing seat with a wide diameter on the outer part of the bearing, and friction will occur in the case of long-term operation.

First of all, it depends on whether you need to add oil, for small motors, marathon motors have been fully used double sealed bearings (bearing model after "ZZ"), this kind of bearing is pre-oiled, no need to re-inject.

Second, look at the motor identification: the motor with the oil injection and discharge device, these motors have been oiled at the factory, but the motor needs to be regularly filled with grease according to the time, grease grade, and oil volume on the oil injection sign after use. Replace the grease according to the provisions of the motor use and maintenance instructions (generally one year).

Types of Grease:

1. In the case of ordinary and minor repairs to replenish the lubricating oil, the lubricating oil in the bearing can be removed according to the situation, and then a little lubricating oil can be added;

Second, the overhaul of all the replacement, first of all, the motor rotor out of the stator, and then clean with gasoline, and wait for all completely dry, and then refuel, and the amount of refueling is 1 3-1 2 of the bearing chamber void, can not be added too much, otherwise the bearing is easy to heat damage.
