In the present embodiment, the oil drain passage 52 is provided as a vertical passage, and the oil drain passage 53 is located at the bottom of the end cap 50, so that the lubricating oil stored in the cavity 51 can be directly discharged to the outside of the motor through the oil drain passage 53 by its own weight. In other embodiments, the oil drain channel 53 is provided in other shapes and other locations, for example, the oil drain channel 53 is provided as a channel having an inclined slope.
The end cap 50 further includes a stopper 54, and the stopper 54 is provided to the oil drain passage 53 to selectively open the oil drain passage 53 or close the oil drain passage 53. When the oil drain passage 53 is opened, the lubricating oil is allowed to flow through the oil drain passage 53 and drain from the cavity 51; when the oil drain passage 53 is closed, the lubricating oil cannot be drained from the cavity 51 via the oil drain passage 53, so that the lubricating oil is stored in the cavity 51.

In this embodiment, the first drainage groove 55 is disposed at a position opposite to the oil inlet channel 52 at the top of the end cover 50, and in practical application, the first drainage groove 55 is a groove milled at the top of the cavity 51 and communicated with the oil inlet channel 52. It will be appreciated that since the bearing 40 is constrained to the cavity 51 by an interference fit, the gap between the bearing 40 and the top inner wall of the cavity 51 is very small, and thus the first drainage groove 55 itself functions to form a gap between the bearing 40 and the top inner wall of the cavity 51, and the first drainage groove 55 allows the injected lubrication oil to drain from the oil inlet passage 52 to the cavity 51 to allow the lubrication oil to enter the bearing 40.
The end cap 50 has a second drainage groove 56, the second drainage groove 56 is provided on the inner wall of the cavity 51, the second drainage groove 56 faces the oil drain channel 53, and the second drainage groove 56 communicates with the oil drain channel 53. In this embodiment, the second drainage groove 56 is disposed at a position opposite to the oil drain channel 53 at the bottom of the end cover 50, and in practical application, the second drainage groove 56 is a groove milled on the bottom inner wall of the cavity 51 and communicated with the oil drain channel 53. It will be appreciated that the bearing 40 is limited to the cavity 51 by means of an interference fit, the cavity 51 is almost filled with the bearing 40, the gap between the bearing 40 and the bottom inner wall of the cavity 51 is very small, and the second drainage groove 56 is a groove formed in the inner wall of the cavity 51, so that the second drainage groove 56 itself plays a role of forming a gap between the bearing 40 and the inner wall of the cavity 51, so that the lubricating oil can be drained to the oil drain channel 53 through the second drainage groove 56, the oil drain channel 53 is prevented from being blocked by the bearing 40, and the lubricating oil is prevented from entering the oil drain channel 53, thus facilitating the drainage of the lubricating oil. In summary, the first drainage groove 55 and the second drainage groove 56 of the present invention are disposed on the inner wall of the cavity 51, wherein the first drainage groove 55 is communicated with the oil inlet channel 52, the second drainage groove 56 is communicated with the oil outlet channel 53, and the first drainage groove 55 and the second drainage groove 56 respectively and correspondingly play a role in guiding lubricating oil in the oil inlet process and the oil outlet process.
Still further, the motor further includes an oil seal inner ring 60, the oil seal inner ring 60 is sleeved on the rotating shaft 31 of the rotor 30 in an interference fit manner, the oil seal inner ring 60 is located in the cavity 51, and the oil seal inner ring 60 is attached to one side of the bearing 40. Because of the interference fit between the oil seal inner ring 60 and the rotary shaft 31, there is no gap between the oil seal inner ring 60 and the rotary shaft 31, and therefore the oil seal inner ring 60 serves to prevent the lubricating oil filled in the bearing 40 from entering the position of the stator 20 along the rotary shaft 31.
The motor further comprises a bearing cap 70, the bearing cap 70 being confined in the cavity 51 of the end cap 50 by means of an interference fit, i.e. the bearing cap 70 being held against the inner wall of the cavity 51 by means of an interference fit. The bearing cap 70 is engaged with one side of the bearing 40, and a gap is provided between the bearing cap 70 and the bearing 40. The bearing cap 70 is sleeved on the periphery of the oil seal inner ring 60, and the oil seal inner ring 60 is nested in the center of the bearing cap 70. The bearing cap 70 serves to fix the position of the bearing 40, and the bearing cap 70 also serves to block the lubricant filled in the inside of the bearing 40 from entering the position of the stator 20. In summary, on one hand, the oil seal inner ring 60 and the bearing cover 70 cooperate together to limit the bearing 40 in the cavity 51, fix the position of the bearing 40, and prevent displacement of the bearing 40; on the other hand, the oil seal inner ring 60 and the bearing cap 70 together seal the cavity 51 to block the lubricant filled inside the bearing 40 from entering the position of the stator 20.
The motor further includes a circlip 80, and the circlip 80 is fitted in a snap spring groove on one side of the end cap 50 and abuts against the bearing cap 70 in such a way as to prevent displacement of the bearing cap 70 during operation of the motor.
In this embodiment, the outer edge of the oil seal inner ring 60 has the first flange 61, the inner edge of the bearing cover 70 has the second flange 71 correspondingly, the positions of the first flange 61 and the second flange 71 on the oil seal inner ring 60 and the positions of the second flange 71 on the bearing cover 70 are reasonably staggered, so that the first flange 61 and the second flange 71 are correspondingly attached together, the oil seal inner ring 60 is nested in the center of the bearing cover 70, and lubricating oil cannot enter the position of the stator 20 between the oil seal inner ring 60 and the bearing cover 70.
In the practical application process, a user adds lubricating oil to the oiling channel 11 through the oiling nozzle 12, and the lubricating oil sequentially passes through the oiling channel 11, the oil inlet channel 52 of the end cover 50 and the first drainage groove 55 and then enters the cavity 51. The lubricating oil then enters the gap between the bearing 40 and the bearing cap 70 along the outer wall of the bearing 40 and finally infiltrates from the bearing 40 side surface to fill the inside of the bearing 40, i.e., the lubricating oil is finally stored in the cavity 51, thereby effecting replenishment of the lubricating oil into the motor to provide lubrication to the junction of the bearing 40 and the rotation 31. Since the stopper 54 is sealed to the drain passage 53 at this time, the lubricating oil does not flow out of the cavity 51. The nozzle 12 directs lubrication oil into the oil feed passage 52 and cavity 51 of the end cap 50.
When it is required to drain the lubricating oil stored in the cavity 51, for example, after the lubricating oil stored in the cavity 51 is used for a while or after expiration, the user opens the oil drain passage 53 by operating the stopper 54, specifically, unscrews the stopper 54 from the oil drain passage 53, i.e., the stopper 54 is detached from the end cap 50, and then the lubricating oil is discharged to the outside of the motor through the second drainage groove 56 and the oil drain passage 53 in sequence.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are by way of example only and are not limiting. The objects of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been shown and described in the examples and embodiments of the invention are susceptible to any variations and modifications without departing from the principles.
