Description

Technical Field

[0001] This utility model belongs to the field of bearing lubrication technology, and in particular relates to an automatic grease replenishment device for servo motor bearings. Background Technology

[0002] Servo motor bearings are an indispensable component of servo motors. Their main function is to support the motor rotor, ensure the rotor's smooth rotation, and effectively withstand axial and radial loads. To improve bearing performance, extend service life, and ensure smooth and reliable operation under various working conditions, grease is added to the servo motor bearings. An automatic grease replenishment device is used when adding grease.

[0003] Existing automatic grease replenishment devices mostly use a grease gun with a grease injection port for direct grease injection. However, servo motor bearings are usually installed inside a closed structure, and after long-term operation, the grease is prone to clumping due to high temperatures. The clumped grease is difficult to remove, preventing the injection of new grease. In this case, the machine must be stopped and the motor manually disassembled to remove the old grease residue before reassembly, severely reducing grease injection efficiency and increasing the complexity of equipment maintenance. Furthermore, automatic grease injection devices rely on operator experience to control the injection volume, which can easily lead to over- or under-injection of grease, affecting bearing performance.

[0004] To address these issues, we have provided an automatic grease replenishment device for servo motor bearings. Utility Model Content

[0029] Please see Figures 1-5Based on the first specific embodiment, the processing mechanism 5 further includes an air outlet pipe 503 disposed on one side of the air inlet pipe 502, and a partition plate 504 fixedly connected to one side of the annular groove 501.

It is fixedly connected to the guide rod 603. A baffle 604 on one side of the 03 blockes and seals the first grease injection hole 605. The first grease injection hole 605 is located at the bottom of the transparent metering cylinder 601. A groove 606 is located at the top of the guide rod 603. A spring 607 is fixedly connected to the bottom of the groove 606. A movable frame 608 is fixedly connected to the top of the spring 607. A limiting hole 609 is located at the top of the transparent metering cylinder 601. Part of the movable frame 608 is located inside the limiting hole 609, which limits its movement. A feed pipe 610 is connected to the top of the piston plate 602. The pipe cap 611 is connected to the surface of the feed pipe 610. A slider is fixedly connected to one side of the movable frame 608.

A knob is fixedly connected to one side of the sealing rod 9. The sealing rod 9 and the sealing sleeve 10 are in close contact.

[0030] The operation process in this embodiment is as follows: When the bearing body 2 needs to be cooled, the external cold air supply device delivers cold air to the annular groove 501 through the air inlet pipe 502. The cold air surrounds the bearing body 2 and is discharged from the air outlet pipe 503, achieving continuous cooling. When the grease needs to be replaced, the device switches to hot air supply. The hot air softens the clumps of old grease, and then the old grease is removed through the extraction hole 8 in conjunction with the external extraction device, without the need to disassemble the motor.

[0031] Pull the piston plate 602 to the designated mark on the transparent metering cylinder 601, open the cap 611, add grease, and seal. Pull the movable bracket 608 upwards to disengage it from the limiting hole 609, rotate it 90 degrees to open the first grease injection hole 605 with the baffle 604, and press down the piston plate 602 to inject grease into the bearing body 2 through the first grease injection hole 605 and the second grease injection hole 7. The cooperation of the spring 607 and the slider ensures the sealing when the baffle 604 returns to its original position.

[0032] The extraction hole 8 is sealed by a threaded sealing rod 9 and a sealing sleeve 10, and the knob design facilitates manual operation. The tight contact between the guide rod 603 and the piston plate 602 prevents grease leakage and ensures the reliability of the metered grease injection process. This achieves automated and precise grease replenishment, while solving the problems of low efficiency and inaccurate grease volume in traditional technologies.
