Description

Technical Field

[0001] This utility model relates to the field of motor accessories, and in particular to a precision shaft for automotive motors. Background Technology

[0002] The car motor is installed on the engine and is used to start diesel and gasoline engines. It reduces the trouble of starting the engine manually, starts quickly, and can be reused, thus improving the convenience of using the car.

[0003] In automotive motors, precision shafts play a crucial role. Precision shafts typically refer to shafts with high precision requirements. These shafts play a key role in supporting rotating parts, transmitting power, and ensuring smooth movement in automotive motors. The shafts work in conjunction with bearings and gears. Because friction is generated between these structures, if the lubrication between them cannot be guaranteed, the overall service life will be reduced during operation, and the accuracy of the shafts will also be compromised.

[0004] Currently, most methods for lubricating shafts involve dripping lubricating oil onto the structural surface or performing lubrication on only the shaft itself. Each lubrication requires disassembly and reassembly, making the operation cumbersome. When working together, it cannot be guaranteed that all parts of the structure will be lubricated. If one part has high friction, the overall accuracy of the application will be reduced. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a precision shaft core for automotive motors. By storing lubricating fluid inside a storage chamber, the lubricating fluid can be guided from inside the outlet groove to one side of the guide ring. The guide ring has a guide plate on its outer ring. During operation, the generated airflow carries the lubricating oil to the shaft core body, bushing, and gear connection points, ensuring that lubrication is provided to all parts simultaneously, rather than just individual parts. This also brings convenience to operation.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution to the problems that lubrication is cumbersome each time and that lubrication cannot be guaranteed between structures when they are working together.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A precision shaft for an automotive motor includes a shaft body, a bushing and a gear on the shaft body, a guide ring with a guide plate at one end of the bushing and the gear, a storage chamber in the middle of the shaft body, and a plurality of outlet grooves at one end of the storage chamber for guiding liquid to the guide ring, the storage chamber extending axially to the front end of the bushing; the outlet grooves are formed on the end side wall of the storage chamber near the bushing.

[0009] Preferably, it also includes several sets of guide grooves, which are used to connect the guide plate and the outlet groove.

[0010] Preferably, the guide ring is designed to be open, and the outer shaft of the shaft core body is provided with an annular inner groove, and the guide ring is fitted into the interior of the annular inner groove through the opening.

[0011] Preferably, the guide ring is provided to be elastic.

[0012] Preferably, at least two sets of the annular inner grooves are provided, and the annular inner grooves are located at the front and rear ends of the bushing and the gear.

[0013] Preferably, one end of the guide ring is connected to a limiting ring to limit the guide ring.

[0014] Preferably, the opening at one end of the storage chamber is provided with a sealing structure, the sealing structure including a sealing element and an inner sealing ring, the sealing element being threadedly connected inside the opening of the storage chamber, and the inner sealing ring being disposed at the inner ring of the sealing element.

[0015] Preferably, positioning grooves are provided on both sides of the guide ring opening, and a locking block is provided inside the positioning groove for positioning the opening.

[0016] Preferably, one end of the card block is rotatably connected to the inside of a positioning groove on one side, and the other end is locked in the inside of a positioning groove on the other side.

[0017] Preferably, the inner end of the card block is provided with a first magnetic block, and the inner wall of the positioning groove is provided with a second magnetic block that can be magnetically connected with the first magnetic block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The precision shaft for automotive motors provided in this application stores lubricant inside a storage chamber, allowing it to be guided from inside the outlet groove to one side of the guide ring. The outer ring of the guide ring is equipped with a guide plate. When the structure is running, the generated airflow carries the lubricant to the shaft body, bushing, and gear connection, ensuring that the structure is simultaneously lubricated, rather than just individual parts. This also brings convenience to the operation.

[0020] This application, through the setting of several sets of guide grooves, can better transfer the lubricating oil to the guide plate when it is discharged from the inside of the discharge groove, so that the lubricating oil is more evenly dispersed under the action of the guide plate.

[0021] This application achieves the limiting effect of the guide ring by setting a limiting ring. After the guide ring is fitted into the annular inner groove, the limiting ring and the outer shaft of the shaft core body fit together.

[0022] This application uses a sealing element and an inner sealing ring to seal the opening for injecting lubricating fluid into the storage chamber. Attached Figure Description

Example

[0035] Please see Figures 1-6 A precision shaft for an automotive motor includes a shaft body 1, on which a bushing 101 and a gear 102 are provided. One end of the bushing 101 and the gear 102 is provided with a guide ring 2 having a guide plate 201. A storage chamber 202 is provided in the middle of the shaft body 1, and one end of the storage chamber 202 is provided with a plurality of outlet grooves 203 for guiding liquid to the guide ring 2. The storage chamber 202 extends axially to the front end of the bushing 101. The outlet grooves 203 are formed on the end side wall of the storage chamber 202 near the bushing 101.

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6In application, the precision shaft for automotive motors of this application mainly consists of a shaft body 1, a bushing 101, and a gear 102. After assembly, a storage chamber 202 is provided in the middle of the shaft body 1, extending along one end of the shaft body 1 to the front end of the bushing 101, where a guide ring 2 is positioned and installed on the outer ring of the shaft body 1. Multiple sets of guide grooves 203, which connect to the externally mounted guide ring 2, are evenly distributed on the end wall of the storage chamber 202 near the bushing 101 and one end of the gear 102. By storing lubricating fluid inside the storage chamber 202, lubricant is released during rotation. The lubricating oil flows through the storage chamber 202 and is guided from the inside of the outlet groove 203 to one side of the guide ring 2. The outer circumference of the guide ring 2 is evenly connected to multiple sets of guide plates 201. During rotation, the generated wind force carries the exported lubricating oil to the connection points of the shaft core body 1, the bushing 101, and the gear 102. During operation, the lubricating oil is carried to every corner, ensuring that the structure can be lubricated at the same time, while avoiding the problem of reduced overall accuracy when only one part has greater friction. At the same time, the depth of the storage chamber 202 is designed to store a certain amount of lubricating oil, so it is not necessary to disassemble and reassemble it every time lubrication is needed, thereby improving the convenience of operation.

[0037] In some embodiments, several guide grooves 204 are provided, wherein one end of the guide plate 201 is connected to the outlet of the outlet groove 203, and the other end extends through the surface of the guide ring 2 to the guide plate 201. In this way, when the lubricating oil is discharged from the inside of the outlet groove 203, it can be better transferred to the guide plate 201, so that the lubricating oil dispersed under the action of the guide plate 201 is more uniform. There are not less than two sets of annular inner grooves 3, which are opened on the outer shaft of the shaft core body 1 and can be located at the front and rear ends of the bushing 101 and the gear 102. The guide ring 2 is designed with an opening and is elastic, so that the opening can be entered and the entire guide ring 2 can be fitted into the annular inner groove 3, thereby installing the guide ring 2. This design is also convenient for disassembly and assembly, and can be installed according to actual use needs, improving adaptability.

[0038] Among them, there are no less than two sets of annular inner grooves 3. In practical applications, an outlet groove 203 that can communicate with the outside of the shaft core body 1 is opened between each annular inner groove 3 and the storage chamber 202, so that the installation position of its guide ring 2 can be changed during application.

[0039] Please see Figure 2 , Figure 3 and Figure 6In this application, a limiting ring 301 is also provided to limit the guide ring 2 that is fitted into the annular inner groove 3. The limiting ring 301 and the annular inner groove 3 are designed as an integral structure. After the guide ring 2 is fitted into the annular inner groove 3, the limiting ring 301 and the outer shaft of the shaft core body 1 are in contact with each other, thus completing the limiting of the guide ring 2.

[0040] Please see Figure 3 , Figure 4 and Figure 5 In this application, a positioning groove 4 and a locking block 401 are also provided. The positioning groove 4 is respectively opened on both sides outside the opening of the guide ring 2. The locking block 401 is rotatably connected to the inside of the positioning groove 4 on one side through a bearing. After opening the locking block 401 and installing the guide ring 2, the locking block 401 is rotated to lock its other end into the positioning groove 4 on the other side, thereby positioning the opening and ensuring stability.

[0041] This application also provides a first magnetic block 402 and a second magnetic block 403. The first magnetic block 402 is installed on the inner end face of the card block 401, and the second magnetic block 403 is installed on the inner wall of the positioning groove 4. When the card block 401 rotates into the positioning groove 4 to position the opening, a magnetic force is generated between the first magnetic block 402 and the second magnetic block 403, so that they are attracted together, thereby further improving the stability of the opening connection.

[0042] Please see Figure 2 and Figure 6 This application also includes a sealing element 5 and an inner sealing ring 501 to seal the opening of the storage chamber 202 for injecting lubricating fluid. The inner sealing ring 501 is located at the inner ring of the sealing element 5. The sealing element 5 is threaded to the inner end of the opening of the storage chamber 202, so that the inner sealing ring 501 can be completely pressed against the outer ring of the opening of the storage chamber 202 to seal the opening.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
