Description

Technical Field

[0001] This utility model relates to the field of motor self-lubrication technology, and in particular to a self-lubricating speed reduction permanent magnet motor. Background Technology

[0002] With the continuous development of technology, electric motors are increasingly used in various fields, especially in high-precision and high-reliability equipment. Permanent magnet motors are widely used due to their advantages such as high efficiency, low energy consumption, and no carbon brush wear. However, permanent magnet motors operate in complex environments, and prolonged operation can easily lead to insufficient lubrication, which in turn affects the performance and service life of the motor. Therefore, how to achieve automatic lubrication of permanent magnet motors, reduce manual maintenance costs, and improve motor operating efficiency and reliability has become an urgent problem to be solved. To this end, the development of a self-lubricating reduction permanent magnet motor that can automatically complete the delivery and quantitative release of lubricating fluid without manual intervention is the key to improving the service life and performance of permanent magnet motors.

[0003] In the prior art, most electric motor lubrication systems rely on regular manual maintenance and manual oiling, or use external pump devices to supply lubricant. These traditional mechanical structures include external motor-driven pumping systems, oil tanks, guide pipes, and lubrication nozzles, etc.

[0004] The main problems in existing technologies are the insufficient automation of lubricant supply, especially after the motor has been running for a long time, it is impossible to accurately lubricate the inside of the motor in time. Since traditional lubrication systems often rely on manual intervention or fixed flow rate delivery, the supply of lubricant is difficult to match with the actual use of the motor and cannot effectively solve the problem of timely lubricant supply. This not only affects the service life of the motor, but may also cause abnormal wear during the operation of the motor. To solve the above problems, a self-lubricating geared permanent magnet motor is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-lubricating speed reduction permanent magnet motor, which aims to improve the problem that it is difficult to lubricate the motor interior manually in the first instance in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-lubricating decelerating permanent magnet motor, comprising a motor body, a support platform fixedly connected to the top of the motor body, an electric push rod fixedly connected to the top of the support platform, a piston fixedly connected to the output end of the electric push rod, a fixed plate fixedly connected to the top of the support platform, and a conveying assembly disposed inside the fixed plate;

[0007] The conveying assembly includes a conveying pipe, the outer wall of which is fixedly connected to the inside of the fixed plate. The piston is slidably connected to the inside of the conveying pipe. A support frame is fixedly connected to the top of the motor body. A limit block is fixedly connected to the top of the support frame. An oil storage tank is slidably connected inside the limit block. A guide pipe is provided at the bottom of the oil storage tank. One end of the guide pipe is fixedly connected to the inside of the conveying pipe. An oil seal is fixedly connected inside the conveying pipe. The other end of the guide pipe is fixedly connected to the bottom of the oil storage tank. A metering component is provided inside the support frame.

[0008] As a further description of the above technical solution: the quantitative component includes a hollow column and a quantitative container. The hollow column is fixedly connected to the bottom of the support frame, the quantitative container is slidably connected inside the hollow column, and a barrier plate is fixedly connected to the outer wall of the quantitative container.

[0009] As a further description of the above technical solution: a small motor is fixedly connected to the top of the motor body, and an eccentric wheel is fixedly connected to the output end of the small motor.

[0010] As a further description of the above technical solution: a disc is slidably connected to the top of the eccentric wheel, and a lifting column is fixedly connected to the top of the disc.

[0011] As a further description of the above technical solution: a second disc is fixedly connected to the top of the lifting column, and the second disc is slidably connected inside the hollow column.

[0012] As a further description of the above technical solution: a spring is sleeved on the outer wall of the lifting column, one end of the spring is fixedly connected to the bottom of the hollow column, and the other end of the spring is fixedly connected to the top of the disc.

[0013] As a further description of the above technical solution: the top of the second disc is fixedly connected to the bottom of the metering container, and the barrier disc is slidably connected inside the metering container.

[0014] As a further description of the above technical solution: a nozzle is provided at one end of the guide pipe, and one side of the nozzle is fixedly connected to one end of the guide pipe.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the piston is pushed to slide inside the delivery pipe by the output end of the electric push rod, so that the lubricating fluid inside the delivery pipe is delivered to the nozzle through the guide pipe, and then injected into the motor through the nozzle, thereby achieving the effect of automatic lubrication of the permanent magnet motor, solving the problem that it is difficult to lubricate the motor inside in time by humans, and improving the service life of the permanent magnet motor.

[0017] 2. In this utility model, the output end of a small motor drives the eccentric wheel to rotate, causing the first disc to move the lifting column upward, which in turn moves the second disc and the metering tank upward. At the same time, the spring is squeezed, causing the lubricating fluid inside the oil storage tank to flow into the guide pipe through the hollow column, thereby achieving the effect of metered release of lubricating fluid. This solves the problem of difficulty in controlling the amount of lubricating fluid when lubricating the motor and improves the accuracy of the self-lubrication process. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: a self-lubricating decelerating permanent magnet motor, including a motor body 1, a support platform 10 fixedly connected to the top of the motor body 1, an electric push rod 7 fixedly connected to the top of the support platform 10, a piston 13 fixedly connected to the output end of the electric push rod 7, a fixed plate 9 fixedly connected to the top of the support platform 10, and a conveying component provided inside the fixed plate 9.

[0026] The conveying assembly includes a conveying pipe 11, the outer wall of which is fixedly connected to the inside of a fixed plate 9. A piston 13 is slidably connected inside the conveying pipe 11. The piston 13 can slide inside the conveying pipe 11 by being pushed by an electric push rod 7, conveying lubricating fluid from the oil storage tank 5 to the inside of the motor body 1, ensuring that all parts of the motor body 1 are lubricated in a timely manner. A support frame 4 is fixedly connected to the top of the motor body 1, and a limit block 6 is fixedly connected to the top of the support frame 4. An oil storage tank 5 is slidably connected inside the limit block 6. A guide pipe 2 is provided at the bottom of the oil storage tank 5, and one end of the guide pipe 2 is fixedly connected to... Connected inside the delivery pipe 11, the function of the guide pipe 2 is to transport the lubricating fluid from the oil storage tank 5 to the delivery pipe 11, thereby realizing the flow and transmission of the lubricating fluid. An oil seal 12 is fixedly connected inside the delivery pipe 11 to seal the lubricating fluid and prevent oil leakage. The other end of the guide pipe 2 is fixedly connected to the bottom of the oil storage tank 5 to ensure that the lubricating fluid can effectively flow out of the oil storage tank 5 and enter the delivery pipe 11. A metering component is set inside the support frame 4 to adjust and control the flow rate of the lubricating fluid, ensuring that the amount of lubricating fluid delivered each time reaches the predetermined standard and preventing excessive or insufficient lubricating fluid.

[0027] Reference Figure 1 - Figure 4 The metering component includes a hollow column 20 and a metering bucket 19. The hollow column 20 is fixedly connected to the bottom of the support frame 4, and the metering bucket 19 is slidably connected inside the hollow column 20. A baffle plate 21 is fixedly connected to the outer wall of the metering bucket 19 to restrict the flow of material inside the metering bucket 19 and prevent excessive or rapid material flow. A small motor 8 is fixedly connected to the top of the motor body 1, and an eccentric wheel 14 is fixedly connected to the output end of the small motor 8. The eccentric wheel 14 drives the first disc 15 to reciprocate by rotating, which pushes the subsequent components to move. A lifting column 17 is slidably connected to the top of the first disc 15, and a second disc 18 is fixedly connected to the top of the lifting column 17. The second disc 18 is slidably connected inside the hollow column 20 to raise or lower the metering bucket. The function of 19 is to control the quantitative conveying of materials. The outer wall of the lifting column 17 is fitted with a spring 16. One end of the spring 16 is fixedly connected to the bottom of the hollow column 20, and the other end of the spring 16 is fixedly connected to the top of the disc 15, which provides a restoring force to ensure that the lifting column 17 can be reset after the motor stops operating. The top of the disc 28 is fixedly connected to the bottom of the metering tank 19 to ensure that the metering tank 19 can be stably connected to other components and maintain a good position during movement. The baffle plate 21 is slidably connected inside the metering tank 19 to further enhance the control of material flow and avoid uneven material distribution. One end of the guide pipe 2 is provided with a nozzle 3, and one side of the nozzle 3 is fixedly connected to one end of the guide pipe 2. The nozzle 3 is used to evenly distribute the material to the designated position.

[0028] Working principle: During the self-lubrication process of the permanent magnet motor, the output of the small motor 8 is first turned to drive the eccentric wheel 14 to rotate. As the eccentric wheel 14 rotates, it lifts the disc 15 upward. As the disc 15 moves upward, it drives the lifting column 17, the disc 18, and the metering cylinder 19 to slide inside the hollow column 20. At the same time, the metering cylinder 19 drives the oil storage tank 5 to slide inside the limit block 6. Simultaneously, the disc 15 compresses the spring 16. As the metering cylinder 19 moves upward, when the circular groove inside the metering cylinder 19 aligns with the circular groove inside the hollow column 20, the lubricating fluid inside the oil storage tank 5 flows through the circular groove into the guide pipe 2, and is then guided through the pipeline route of the guide pipe 2. In the next stage, after the eccentric wheel 14 rotates one revolution, the spring 16 releases its elastic force, causing the spring 16, disc 18, and metering tank 19 to reset. Then, the blocking disc 21 stops the flow of liquid inside the oil storage tank 5, thus achieving the effect of metered release of lubricating fluid. After the lubricating fluid flows into the delivery pipe 11 through the guide pipe 2, the output end of the electric push rod 7 drives the piston 13 to slide inside the delivery pipe 11. During the sliding process, the piston 13 pushes the lubricating fluid inside the delivery pipe 11, so that the lubricating fluid is pushed into the nozzle 3 through the guide pipe 2. Then, the lubricating fluid is injected into the motor body 1 through the nozzle 3, thereby achieving the purpose of self-lubrication of the motor body 1.
