[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a permanent magnet frequency conversion integrated machine motor shaft mechanism that is easy to lubricate provided by the utility model;

[0024] Figure 2 for Figure 1 The structural diagram of the right view of the installation cover is shown; Figure 3 for Figure 1 The structural diagram of the left view of the connecting cover shown; Figure 4 for Figure 2 The structural schematic diagram of the right side view of the oil storage box shown; Figure 5 for Figure 1 The enlarged schematic diagram of the structure of area A is shown, a permanent magnet frequency conversion integrated machine motor shaft mechanism that is easy to lubricate, comprising: a body 1, a lubrication assembly 2 is arranged on the right side of the body 1;

[0025] The lubrication assembly 2 includes a rotating shaft 21 which is arranged on the inner side of the body 1 and can rotate laterally. A mounting cover 22 is arranged on the right side of the body 1. A connecting cover 23 is arranged on the right side of the mounting cover 22. The right end of the rotating shaft 21 passes through the inner side of the body 1 and extends to the right side of the connecting cover 23. An oil nozzle 24 is connected to the right side of the connecting cover 23 and located above the rotating shaft 21.

[0026] The inner cavity formed between the connecting cover 23 and the mounting cover 22 provides a lubrication area for the rotor, and such an arrangement can facilitate installation on a motor that has already been finalized.

[0027] Two fixing frames 25 are arranged in a mirror image on the right side of the mounting cover 22. Two sliding rods 26 are arranged vertically on the inner sides of the two fixing frames 25. An oil storage box 27 is arranged on the peripheral side surfaces of the two sliding rods 26 so as to slide up and down along the height direction thereof.

[0028] The oil storage box 27 slides up and down on the peripheral side surfaces of the two sliding rods 26. When the oil storage box 27 moves upward, the oil outlet 29 is driven upward. The oil outlet 29 moves upward and gradually approaches the oil nozzle 24 on the left side of the connecting cover 23, forming a connection and delivering the lubricating oil into the oil nozzle 24, and the lubricating oil is sprayed onto the peripheral side surfaces of the rotor through the oil nozzle 24.

[0029] Springs 28 are provided on the circumferential sides of the two sliding rods 26 and at the top of the oil storage box 27 and the sliding connection therewith. When the two springs 28 are stationary, the oil storage box 27 is located at the bottom of the opposite side of the two fixing frames 25 .

[0030] Through the setting of the spring 28, when the oil storage box 27 is not lifted up by the protrusion 5, the oil storage box 27 is pressed back to the bottom under the pressure of the spring 28, so that the oil outlet 29 contacts and closes with the left side of the connecting cover 23, and the output of the lubricating oil is stopped.

[0031] An oil outlet 29 is provided on the right side of the oil storage box 27, and the right side of the oil outlet 29 is tightly fitted to the left side of the connecting cover 23. The top of the oil storage box 27 is connected to an oil inlet pipe 4, and the top end of the oil inlet pipe 4 passes through the inner side of the mounting cover 22 and extends to the top thereof, and the top end of the oil inlet pipe 4 is connected to a funnel.

[0032] The funnel is provided to facilitate the injection of used lubricating oil and recovered lubricating oil into the oil storage box 27 .

[0033] A protrusion 5 is provided on the peripheral side of the rotating shaft 21 and at the bottom of the oil storage box 27 . When the protrusion 5 rotates to the top of the peripheral side of the rotating shaft 21 , the right side of the oil outlet 29 communicates with the left side of the oil injection nozzle 24 .

[0034] By setting the protrusion 5, when the shaft 21 rotates, the protrusion 5 is driven to rotate along its axis. When the protrusion 5 rotates to the top of the shaft 21, the bottom of the oil storage box 27 is lifted up. By setting protrusions 5 of different sizes, the height of the oil storage box 27 can be adjusted, thereby adjusting the amount of lubricating oil sprayed.

[0035] An oil receiving box 6 is provided on the right side of the connecting cover 23 and below the rotating shaft 21 so as to be slidable forward and backward, and a filter screen 7 is provided on the top of the oil receiving box 6 .

[0036] By setting the oil receiving box 6 and the filter screen 7, when part of the lubricating oil drips, it will be filtered by the filter screen 7 and then fall into the oil receiving box 6. After a period of time, the oil receiving box 6 can be removed and the lubricating oil inside can be poured into the funnel for recycling.

[0037] The working principle of the motor shaft mechanism of a permanent magnet frequency conversion integrated machine that is easy to lubricate provided by the utility model is as follows:

[0038] Step 1: When in use, pour the required lubricating oil into the oil storage box 27 through the funnel. When the rotating shaft 21 rotates, the protrusion 5 is driven to rotate, and then the protrusion 5 lifts the oil storage box 27 once when it rotates one circle. When the oil storage box 27 is lifted up, the oil outlet 29 is connected with the oil nozzle 24 on the left side of the connecting cover 23, and the lubricating oil can enter the oil nozzle 24 to lubricate the rotor through the oil nozzle 24.

[0039] Step 2: By setting the spring 28, when the oil storage box 27 is not lifted up by the protrusion 5, the oil storage box 27 is pressed back to the bottom under the pressure of the spring 28, so that the oil outlet 29 is in contact with the left side of the connecting cover 23 and closed, and the output of the lubricating oil is stopped, and the amount of oil output can be adjusted by changing the height of the protrusion 5;

[0040] Step 3: The lubricating oil not consumed by the rotor will drip onto the filter screen 7, and after filtering out impurities, it will fall into the oil receiving box 6 at the bottom. After a period of time, the lubricating oil in the oil receiving box 6 can be poured back into the funnel for recycling.

[0041] Compared with the related art, the permanent magnet frequency conversion integrated machine motor shaft mechanism provided by the utility model which is easy to lubricate has the following beneficial effects:

[0042] The rotation of the rotating shaft 21 drives the protrusion 5 to rotate, and then the oil storage box 27 is lifted up once when the protrusion 5 rotates one circle. When the oil storage box 27 is lifted up, the oil outlet 29 is connected with the oil nozzle 24 on the left side of the connecting cover 23, and the lubricating oil can enter the inside of the oil nozzle 24, and the rotor is lubricated by the oil nozzle 24. The structure is simple and practical, which can not only save the time of manual lubrication of the rotor, but also can adjust the amount of lubricating oil sprayed, and the use effect is good.
