Technical field: [0001] The invention belongs to the technical field of automation equipment processing and manufacturing, and in particular relates to an automatic oiling device for motor rotor bearings. Background technique: [0002] The motor rotor bearing is a special bearing specially used in electric motors or motors. It is a part that supports the shaft. It can guide the rotation of the shaft and can also bear the idling parts on the shaft. The motor rotor bearing passes through smooth metal balls or rollers. These balls or rollers "carry" the load and support the motor shaft so that the motor rotor can rotate smoothly. Due to the importance of the role of the motor rotor bearing, generally in the production of industrial motors, a circle of lubricating oil will be smeared on the outside of the bearing to play the role of lubricating the motor bearing, thereby prolonging the service life of the motor.

Due to the importance of the role of the motor rotor bearing, generally in the production of industrial motors, a circle of lubricating oil will be smeared on the outside of the bearing to play the role of lubricating the motor bearing, thereby prolonging the service life of the motor. However, due to the location of some motors If the environment or its own operating temperature is too high, cooling air teeth are usually added to the motor rotor. Generally, the height of the cooling air teeth is relatively high, which may block some or even all of the bearings. It is relatively laborious, and the traditional smearing process can only be done manually; Chinese patent 201420365417.3 discloses an unpowered automatic oiling device for motor rotor ball bearings, including an oiling inclined frame, a groove set on the oiling inclined frame and a groove in the concave Oiled rails on both sides of the groove, linoleum is set in the oiled rail, and a stop plate is installed at the end of the oiled inclined frame.
