Description

Technical Field

[0001] This utility model relates to the field of armature shaft technology, specifically a novel automotive starter armature shaft. Background Technology

[0002] The starter armature shaft is one of the key components inside the starter motor. It is mainly used to support the armature and transmit power, playing an important role in the conversion of electrical energy into mechanical energy.

[0003] A gearbox is required on the electric drive shaft to transmit torque and change speed. In this case, the surfaces of the transmission gears in the gearbox need to be coated with lubricating oil. However, over time, the lubricating oil will accumulate at the bottom of the gearbox, resulting in less and less lubrication on the transmission gears and aggravating wear between the transmission gears. Therefore, a self-lubricating structure is required on the electric drive shaft to ensure that there is always enough lubrication on the transmission gears. Utility Model Content

[0004] The purpose of this invention is to provide a novel automotive starter armature shaft to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an electric drive housing and a gearbox. An electric drive body is installed inside the electric drive housing. The front end of the electric drive body extends out of the electric drive housing and is fixedly connected to a drive shaft. An output shaft is installed inside the gearbox. The drive shaft and the output shaft are fixedly connected to meshing transmission gears at one end of the gearbox. A conveying hole is opened inside the drive shaft. The two openings of the conveying hole are located outside the drive shaft and are respectively an oil inlet and an oil injection nozzle. A rotating sleeve is rotatably connected to the drive shaft at a position corresponding to the oil inlet. A conveying pipe is fixed between the rotating sleeve and the bottom of the gearbox.

[0006] Preferably, a delivery pump is installed on the delivery pipe, and the two ends of the inner side of the rotating sleeve are rotatably connected to the drive shaft through sealed bearings.

[0007] Preferably, a filter frame is installed inside the gearbox and below the transmission gear. Side plates are fixed at both ends of the filter frame. A pair of fixing plates are fixed to the inner side wall of the gearbox. A positioning post is fixed to the bottom of the side plate. The bottom of the positioning post is inserted into and passes through the fixing plate.

[0008] Preferably, a limiting post is fixed inside the gearbox, and the limiting post is located at the middle position of the upper end of the filter frame.

[0009] Preferably, an annular plate is fixed at the inner opening of the gearbox, a front cover is installed at the front end of the gearbox, and the output shaft extends out of the front cover.

[0010] Preferably, the oil injection nozzles are circumferentially distributed on the drive shaft and are all inclined toward the transmission gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using the lubricating oil circulation method, the lubricating oil in the gearbox of the armature shaft can be continuously re-sprayed to the transmission gear, which can achieve the purpose of self-lubrication. At the same time, the lubricating oil filter structure can prevent debris or foreign objects from clogging the oil spray head, ensuring that the equipment can operate normally.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: including an electric drive housing 1 and a gearbox 5, an electric drive body 2 is installed inside the electric drive housing 1, the front end of the electric drive body 2 extends out of the electric drive housing 1 and is fixedly connected to a drive shaft 3, an output shaft 4 is installed inside the gearbox 5, and a transmission gear 7 that meshes with each other is fixed at one end of the gearbox 5 on the drive shaft 3 and the output shaft 4, respectively. A conveying hole is opened inside the drive shaft 3, and the two ends of the conveying hole are located outside the drive shaft 3, and are respectively an oil inlet 31 and an oil injection nozzle 33. A rotating sleeve 32 is rotatably connected on the drive shaft 3 at a position corresponding to the oil inlet 31, and a conveying pipe 6 is fixed between the rotating sleeve 32 and the bottom of the gearbox 5.

[0018] A delivery pump 61 is installed on the delivery pipe 6. The two ends of the inner side of the rotating sleeve 32 are rotatably connected to the drive shaft 3 through sealed bearings. The oil injection nozzles 33 are distributed circumferentially on the drive shaft 3 and are all inclined toward the transmission gear 7.

[0019] A filter frame 8 is installed inside the gearbox 5 and below the transmission gear 7. Side plates 81 are fixed at both ends of the filter frame 8. A pair of fixing plates 83 are fixed on the inner side wall of the gearbox 5. A positioning post 82 is fixed at the bottom of the side plate 81. The bottom of the positioning post 82 is inserted into and passes through the fixing plate 83. A limit post 53 is fixed inside the gearbox 5. The limit post 53 is located at the middle of the upper end of the filter frame 8. An annular plate 52 is fixed at the inner opening of the gearbox 5. A front cover 51 is installed at the front end of the gearbox 5. The output shaft 4 extends out of the front cover 51.

[0020] Working principle: First, connect the entire device to an external power source. The rotation of the electric drive body 2 after being powered on drives the drive shaft 3 to rotate, and the transmission gear 7 drives the output shaft 4 to rotate. During this process, the lubricating oil on the surface of the transmission gear 7 will continuously accumulate at the bottom of the gearbox 5 under the action of gravity. At this time, the lubricating oil can be drawn out from the gearbox 5 by the drive of the delivery pump 61, and transported into the rotating sleeve 32 through the delivery pipe 6. Finally, it enters the drive shaft 3 through the oil inlet 31 and is sprayed out from the oil injection nozzle 33, re-adhering to the surface of the transmission gear 7 to achieve the purpose of self-lubrication. In addition, during the circulation process, the lubricating oil will pass through the filter frame 8 to filter the lubricating oil, which can effectively prevent foreign objects in the lubricating oil from entering the circulation and causing the oil injection nozzle 33 to be blocked. When installing the filter frame 8, the positioning pins 82 at both ends of the side plate 81 can be inserted into the fixing plate 83, and the middle position is limited by the arc-shaped limit pin 53 to ensure that the filter frame 8 is stably installed at the bottom of the gearbox 5 and located outside the transmission gear 7.
