Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to a motor whose shaft is designed for easy application of lubricating oil. Background Technology
[0002] An electric motor is a device that converts electrical energy into mechanical energy. Its core principle is that the force generated by the current in the magnetic field drives the rotor to rotate, thereby outputting mechanical power. In order to reduce the wear of the motor output shaft during use, it is usually necessary to apply lubricating oil to the motor output shaft regularly.
[0003] For example, the utility model patent with authorization announcement number CN222508993U discloses a motor based on the motor shaft that is easy to apply lubricating oil to. The lubricating oil box is driven by the oil inlet pipe to slide on the outer wall of the motor output shaft and apply lubricating oil. Proper lubrication can prevent the bearing from wearing out prematurely due to increased friction, thereby extending the service life of the bearing and even the entire motor. In addition, the lubricating oil can remove most of the frictional heat generated inside the bearing, playing an effective heat dissipation role and preventing the bearing from overheating.
[0004] Although the aforementioned motor can perform the application of lubricating oil, it is only suitable for lubricating oils with relatively good fluidity. If lubricating oils with poor fluidity are used, it cannot be guaranteed that the lubricating oil can flow out normally through the oil inlet hole, resulting in poor applicability. In addition, when adding lubricating oil through the opening at the top of the oil inlet pipe, it is easy to cause the lubricating oil to flow out, making it inconvenient to use.
[0005] Therefore, it is necessary to invent a motor based on a motor shaft that is easy to apply lubricating oil to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a motor based on a shaft that facilitates the application of lubricating oil. This design is applicable to different types of lubricating oil, broadening its applicability, and allowing for more convenient lubricating oil suction. Furthermore, it allows for precise addition of lubricating oil to avoid over- or under-addition, resulting in better performance in actual use. This addresses the problems mentioned in the background art, which only applies to lubricating oils with relatively good fluidity. If lubricating oils with poor fluidity are used, it cannot be guaranteed that the lubricating oil will flow normally through the oil inlet, leading to poor applicability. Additionally, when adding lubricating oil through the opening at the top of the oil inlet pipe, it is easy for lubricating oil to leak out, making it inconvenient to use.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings were flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 2 This is a schematic diagram of a blocking mechanism 2 for a motor based on an embodiment of the present disclosure, which facilitates the application of lubricating oil to the motor shaft.
[0029] Figure 3 This is a schematic diagram of a lubricating oil metering and suction mechanism 3 for a motor based on a motor shaft that facilitates the application of lubricating oil, according to one embodiment of the present disclosure.
[0030] like Figures 1-3 As shown, the motor disclosed herein, which facilitates the application of lubricating oil to the motor shaft, may include components such as: motor assembly 1, blocking mechanism 2, and lubricating oil metering and suction mechanism 3.
[0031] like Figure 1 As shown in this disclosure, the motor assembly 1 includes a motor body 11, a motor shaft 12 is rotatably nested on the front of the motor body 11, a control box 13 is fixedly disposed on the top of the motor body 11, and a base 14 is fixedly disposed on the bottom of the motor body 11.
[0032] It should be noted that the aforementioned motor assembly 1 and its constituent components are all existing technologies, and therefore will not be described in detail here.
[0033] like Figure 2 As shown, in a preferred embodiment, the blocking mechanism 2 includes a blocking cover 21 sleeved on the outside of the motor shaft 12. An annular fixing plate 22 is fixedly sleeved on the rear end of the outer side of the blocking cover 21. The annular fixing plate 22 is fixedly connected to the outer shell of the motor body 11. An avoidance opening 23 is provided in the center of the front side of the blocking cover 21. The radius of the avoidance opening 23 is larger than the radius of the motor shaft 12. An installation opening 24 is provided on the top of the blocking cover 21.
[0034] Therefore, after the blocking cover 21 is fitted onto the outside of the motor shaft 12 through the clearance opening 23, the annular fixing plate 22 can be welded onto the outer shell of 11b, thereby completing the installation and fixing of the blocking mechanism 2 and the lubricating oil metering suction mechanism 3. During the subsequent lubricating oil addition process, the blocking cover 21 can block the lubricating oil and prevent the lubricating oil from falling directly from the outer surface of the motor shaft 12 under the action of gravity.
[0035] like Figure 3As shown in this disclosure, the lubricating oil metering suction mechanism 3 includes a piston cylinder 31 fixedly disposed inside the installation opening 24. An oil outlet pipe 32 is fixedly disposed through the bottom center of the piston cylinder 31, and an oil inlet pipe 33 is fixedly disposed through the bottom right side. Both the oil outlet pipe 32 and the oil inlet pipe 33 are provided with one-way valves. A hose 34 is fixedly sleeved at the right end of the oil inlet pipe 33. The piston plate 35 is slidably disposed on the inner side of the piston cylinder 31 in the vertical direction. A limiting ring is fixedly disposed at the top of the inner side of the piston cylinder 31 to prevent the piston plate 35 from falling out. The piston plate 35 is located at the bottom of the limiting ring. A piston shaft 36 is fixedly disposed at the top of the piston plate 35. A gripping sleeve 37 is slidably sleeved on the outer side of the piston cylinder 31 in the vertical direction and fixedly connected to the top of the piston shaft 36.
[0036] Therefore, to facilitate the actual addition of lubricating oil, first insert the end of the hose 34 into the lubricating oil container, then grasp the gripping sleeve 37 and slide it upwards. As the gripping sleeve 37 moves upwards along the outer wall of the piston cylinder 31, it drives the piston plate 35 to continuously move upwards inside the piston cylinder 31 via the piston shaft 36. At this time, due to the restriction of the one-way valve on the oil outlet pipe 32, the negative pressure generated inside the piston cylinder 31 is transmitted to the lubricating oil container through the oil inlet pipe 33 and the hose 34, thereby allowing the lubricating oil to enter the piston cylinder 31 through the hose 34 and the oil inlet pipe 33. As the piston plate 35 continues to move upwards, the top of the piston plate 35 contacts the limiting ring and is blocked by the limiting ring. Then, the holding sleeve 37 is slid downwards. At this time, the holding sleeve 37 drives the piston plate 35 through the piston shaft 36 to push the lubricating oil inside the piston cylinder 31. This causes the lubricating oil inside the piston cylinder 31 to fall onto the top of the motor shaft 12 through the oil outlet pipe 32. As the lubricating oil is continuously added and blocked by the inner wall of the baffle 21, the lubricating oil eventually flows along the outer surface of the motor shaft 12, thus completing the coating. Compared with the existing technology, it can be applied to different types of lubricating oil, with a wider range of applications. At the same time, it can more conveniently complete the lubricating oil suction operation. In addition, it can add a quantitative amount to avoid adding too much or too little lubricating oil, resulting in better actual use effect.
[0037] like Figure 3 As shown, the lubricating oil metering suction mechanism 3 also includes multiple anti-slip protrusions 38 that are uniformly sleeved on the outside of the grip sleeve 37 in a vertical direction. The multiple anti-slip protrusions 38 are fixedly connected to the grip sleeve 37 so that when the grip sleeve 37 is held and slid up or down, the multiple anti-slip protrusions 38 can increase the contact area with the palm, thereby increasing the friction between the grip sleeve 37 and the palm, making it more convenient to raise and lower the grip sleeve 37.
[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
