1. Check whether the oil level of the brushless gear motor Factory meets the requirements before starting. Follow the prompts to open or remove the vent cover to make it ventilate smoothly, and check if the rotation is flexible.

2. The no-load operation should be carried out about half an hour before the load test operation, and it is confirmed that the no-load operation can be loaded and operated without failure. The test operation should always check the operation: no abnormal shock, vibration, no leakage, or oil leakage. The temperature should not exceed 60℃, and the high oil temperature should not exceed 100℃ (while checking the daily work at any time), it can work normally.

3. If there is an abnormal situation in the operation, the inspection should be stopped, and the work can be continued after the problem is found and eliminated. Check the lubrication status from time to time, pay attention to the amount of oil replenishment, and remove and replace damaged lubricating oil on time.

4. If the installation azimuth is changed, the oil mirror, oil plug, and vent cap can generally be removed.

5. Hard tooth surface gear deceleration should be kept clean at all times, and no dust on the outer surface, so as not to affect heat dissipation.

6. Storage: dry and ventilated. Store at room temperature. Anti-rust treatment should be carried out when the storage period exceeds three months. When the machine is placed for about a year, check whether the oil seal is aging and whether the oil is damaged during use.

As a vulnerable part, the life of the motor (especially the brush motor) component is relatively short for the entire motion system. Therefore, it is very necessary to understand some precautions when using the motor.

 

1. Machining of China planetary gearmotor company (gearbox) shaft: According to different loads, customers often need to process the output shaft, such as: drilling, milling, keyway, etc. The safest method is to fix the load on the shaft through the top wire. For further tightening, two top wires with an angle of 90° can be used for fixing. If the output shaft must be processed, it must be ensured that the axial and radial forces on the output shaft do not exceed the indicators given in the parameter table during the machining process, otherwise the bearing of the output shaft will easily be damaged. In the worst case, the shaft vibration increases, in the worst case, the motor and gear box are completely unusable, and the most serious may even damage the encoder at the rear of the motor and cause a complete set of products to be scrapped.

 

2. Motor locked-rotor: After the motor is locked, the consumed current reaches the maximum value and all the electrical energy is converted into heat energy. This may cause the motor temperature to rise sharply in a short time. Once it exceeds the allowable operating temperature range, it will There will be serious consequences such as magnet demagnetization and coil short circuit. Motor locked-rotor current = voltage applied to the motor/motor terminal resistance

 

3. Soldering lugs at the end of the motor: For a brushed motor, there are two metal lugs at the end to connect to the power supply. The solder tab has a certain degree of flexibility, but it cannot be bent repeatedly. More than three times may break

The correct installation and maintenance of the planetary gearbox is the key to the normal operation of the planetary motor. Therefore, when you install the planetary gear motor, please install it strictly according to the following installation sequence.

Step 1: Before installation, confirm whether the motor and planetary gear reducer are complete and undamaged, and strictly whether the dimensions of each part adjacent to the drive motor and the reducer are aligned. This refers to the size and common service between the positioning boss and shaft diameter of the drive motor flange and the positioning groove and aperture of the reducer flange; wipe and dispose of the common appearance of dirt and burrs.

Step 2: Unscrew the screw plug on the process hole on the side of the flange of the reducer, rotate the input end of the reducer, align the holding hexagon socket screw cap with the process hole, insert the hexagon socket tool to loosen and tighten the hexagon socket screw .

Step 3: Hold the drive motor so that the keyway on the shaft is perpendicular to the screw in the input end hole of the reducer, and insert the drive motor shaft into the input end hole of the reducer. When inserting, it must be ensured that the concentricity of the two is equal and the flanges on both sides are parallel. It seems that the difference in heart degree, etc. or the unyielding of the flanges on both sides must be investigated for the reason. In addition, it is strictly forbidden to use hammering during the installation, that is, it can prevent the axial or radial force of the hammer from damaging the bearings of the two, and it can be determined by the feel of the device to determine whether the two are in line. The key to decisively that the two have the same concentricity and flange parallelism is: after the two are inserted into each other, the two flanges are basically tight, and the loopholes are the same.

Step 4: In order to ensure that the connecting force of the two flanges is symmetrical, first screw the fastening screws of the drive motor arbitrarily, but do not tighten them; then gradually tighten the four fastening screws according to the diagonal position; finally tighten the planetary gear Hold the screw in the input end hole of the geared motor. Be sure to tighten the fastening screw of the drive motor first, and then tighten the input end hole of the reducer to hold the screw. Meticulous: The accurate placement between the reducer and the machine setting equipment is similar to the accurate placement between the planetary gear reducer and the drive motor. The key is that the output shaft of the planetary reducer must be concentrically aligned with the input shaft of the driven department. With the continuous and in-depth growth of the application of control motors, the application of planetary gear motors in the field of activity control drives will also increase.
