Description

Technical Field

[0001] This application relates to the field of automotive gear technology, and in particular to a novel shock-absorbing and lubricating automotive gear. Background Technology

[0002] Automotive gears are key components of the automotive transmission system, primarily responsible for transmitting power and changing the direction of rotational speed and torque. They directly affect the vehicle's power performance and driving stability. They are typically made of high-strength alloy steel and undergo heat treatment processes such as carburizing and quenching to obtain a high-hardness surface and a good toughness internal structure.

[0003] During the operation of a car, gears mesh with each other at high speeds, generating intense friction and compression between the tooth surfaces. This results in the generation of a large amount of heat. As the temperature rises, the viscosity of the lubricating oil decreases and its fluidity increases, causing the oil film that was originally attached to the gear surface to become thinner or even break, making it difficult to form effective lubrication protection.

[0004] When automotive gears are not adequately lubricated, the dry friction between the tooth surfaces will increase significantly, which will not only exacerbate gear wear and shorten gear life, but also produce harsh noise. Furthermore, excessive wear may lead to pitting, peeling, or even tooth breakage on the gear tooth surfaces. Utility Model Content

[0005] The purpose of this application is to provide a novel shock-absorbing and lubricating automotive gear to address the problem of gear lubrication affecting the normal use of gears.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A novel shock-absorbing and lubricating automotive gear includes a gear body with a plurality of teeth arranged in a circumferential array fixed on the gear body. An mounting ring is fixed inside the gear body. A lubrication structure is provided on the gear body, including an oil reservoir cavity formed inside the gear body. An oil injection hole is formed on the surface of the gear body, and an oil supply channel is formed inside each tooth, penetrating the meshing surface of the teeth. The oil injection hole, oil reservoir cavity, and oil supply channel are all interconnected. A sealing component is provided inside the oil injection hole.

[0007] By adopting the above technical solution, before the gear is used, an appropriate amount of lubricating oil is added into the oil storage chamber through the oil injection hole, and then the sealing component is used to seal it. When the gear is working, as the gear rotates at high speed, the lubricating oil in the oil storage chamber flows out slowly along the oil supply channel under the action of centrifugal force. When the teeth of the gears come into contact with the teeth of other gears, the lubricating oil plays a lubricating role, reducing the friction between the gears. At the same time, the lubricating oil forms a damping effect between the teeth, thereby playing a shock absorption role, so as to make the gear run stably.

[0008] Furthermore, the sealing assembly includes a sealing head threaded into the oil injection hole, a screw head fixed to the end of the sealing head, a connecting groove on the surface of the gear body, the oil injection hole being located at the bottom of the connecting groove, and the screw head being embedded inside the connecting groove.

[0009] By adopting the above technical solution, the plug head is connected to the oil filling hole by turning the screwdriver, and the screw head will be embedded in the connecting groove, thereby achieving the sealing of the oil filling hole.

[0010] Furthermore, a sealing groove is provided at the bottom of the connecting groove, a sealing sleeve is fixed inside the sealing groove, and a sealing ring is fixed on the side of the screw head, the sealing ring being slidably inserted into the sealing sleeve.

[0011] By adopting the above technical solution, after connecting the plug head to the oil injection hole, the sealing ring is located inside the sealing sleeve. The sealing sleeve and the sealing ring can improve the sealing between the screw head and the oil injection hole, thereby reducing the leakage of lubricating oil.

[0012] Furthermore, a sealing gasket is fixed to the end of the sealing sleeve, the sealing gasket is located inside the connecting groove, and the sealing gasket abuts against the end of the screw head.

[0013] By adopting the above technical solution, the sealing gasket can increase the sealing between the connecting groove and the screw head, further improve the sealing effect, and reduce the leakage of lubricating oil.

[0014] Furthermore, the sealing sleeve is a corrosion-resistant elastic rubber sleeve, and the sealing gasket is a corrosion-resistant elastic rubber gasket.

[0015] By adopting the above technical solutions, the sealing sleeves and gaskets made of corrosion-resistant elastic rubber have good corrosion resistance and sealing performance.

[0016] Furthermore, a connecting rope is fixed inside the oil storage cavity, and the connecting rope is fixedly connected to the sealing head.

[0017] By adopting the above technical solution, the connecting rope can prevent the sealing head from being lost due to random placement when disassembling the sealing head.

[0018] Furthermore, a barrier net is provided at the end of the oil supply channel away from the oil storage chamber, and the barrier net is fixedly connected to the teeth.

[0019] By adopting the above technical solution, the barrier mesh can effectively reduce the amount of external dust entering the oil supply channel when the gear is working, and reduce the phenomenon of dust entering the oil injection channel causing oil flow obstruction.

[0020] Furthermore, the tooth surface is provided with a wear-resistant layer, which is a hard chrome plating layer.

[0021] By adopting the above technical solution, the hard chrome plating can effectively improve the wear resistance of the gear, thereby increasing its service life.

[0022] In summary, this application includes at least one of the following beneficial effects: 1. In this application, an appropriate amount of lubricating oil is added into the oil storage chamber through the oil injection hole. After the oil injection is completed, the oil injection hole is sealed. When the gear is working, as the gear rotates at high speed, the lubricating oil in the oil storage chamber slowly flows out along the oil supply channel under the action of centrifugal force and flows onto the teeth. When the teeth of the gears come into contact with the teeth of other gears, the lubricating oil plays a lubricating role, reducing the friction between the gears, thereby reducing abnormal noise of the gear parts. In addition, the lubricating oil forms a damping effect between the teeth, thereby playing a shock absorption role and making the gear run stably.

[0023] 2. In this application, when sealing the oil injection hole, the sealing head is connected to the corresponding oil injection hole, and the sealing ring is connected to the corresponding sealing sleeve. Then, the screwdriver is used to turn the screw head, so that the sealing head gradually enters the oil injection hole and the sealing ring gradually enters the sealing sleeve. The screw head is continuously turned until the sealing head is tightened, thus sealing the oil injection hole. After tightening, the sealing ring enters the sealing sleeve and fits tightly with the sealing sleeve, and the sealing gasket fits with the screw head, completing the sealing of the oil injection hole. The sealing sleeve, sealing ring and other structures provide the first layer of sealing, and the sealing gasket provides the second layer of sealing, which can improve the sealing performance at the oil injection hole and effectively reduce the phenomenon of lubricating oil seeping out from the oil injection hole when the gear rotates at high speed.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a novel shock-absorbing and lubricating automotive gear.

[0028] Reference Figure 1 A novel shock-absorbing and lubricating automotive gear includes a gear body 11, on which a plurality of teeth 11 arranged in a circumferential array are fixed. An mounting ring 12 is fixed inside the gear body 11. A lubrication structure 2 is provided on the gear body 11. The lubrication structure 2 includes an oil storage chamber 21 opened inside the gear body 11. An oil injection hole 22 is opened on the surface of the gear body 11. An oil supply channel 23 is opened inside the teeth 11. The oil supply channel 23 penetrates the meshing surface of the teeth 11. The oil injection hole 22, the oil storage chamber 21, and the oil supply channel 23 are all interconnected. A sealing component is provided inside the oil injection hole 22.

[0029] Before use, a suitable amount of lubricating oil is added to the oil reservoir 21 through the oil filling hole 22, and then sealed using a sealing assembly. The mounting ring 12 inside the gear body 11 is fitted onto the drive shaft for gear mounting. When the gear is working, as it rotates at high speed, the lubricating oil inside the oil reservoir 21 slowly flows out along the oil supply channel 23 under the action of centrifugal force, flowing onto the teeth 11. When the teeth 11 contact with the teeth 11 of other gears, the lubricating oil serves to lubricate, reducing the friction of the gear components and thus reducing abnormal noise. Furthermore, the lubricating oil creates a damping effect between the teeth 11, thereby reducing vibration and ensuring stable gear operation. Regularly adding lubricating oil to the oil reservoir 21 maintains lubrication between the gears.

[0030] The sealing assembly includes a sealing head 3 threadedly connected inside the oil injection hole 22. A screwdriver 31 is fixed at the end of the sealing head 3. A screwdriver insertion hole is provided on the surface of the screwdriver 31 for engaging with a screwdriver. A connecting groove 37 is provided on the surface of the gear body 11. The oil injection hole 22 is located at the bottom of the connecting groove 37. The screwdriver 31 is embedded inside the connecting groove 37.

[0031] Among them, the bottom of the connecting groove 37 is provided with a sealing groove 32, and a sealing sleeve 33 is fixed inside the sealing groove 32. A sealing ring 34 is fixed on the side of the screw head 31, and the sealing ring 34 is slidably inserted into the sealing sleeve 33.

[0032] In addition, a sealing gasket 35 is fixed to the end of the sealing sleeve 33. The sealing gasket 35 is located inside the connecting groove 37 and abuts against the end of the screw head 31.

[0033] Furthermore, the sealing sleeve 33 is a corrosion-resistant elastic rubber sleeve, and the sealing gasket 35 is a corrosion-resistant elastic rubber gasket.

[0034] After oil filling is completed, connect the plug head 3 to the corresponding oil filling hole 22, and connect the sealing ring 34 to the corresponding sealing sleeve 33. Then, use a screwdriver to turn the screw head 31, so that the plug head 3 gradually enters the oil filling hole 22, and the sealing ring 34 gradually enters the sealing sleeve 33. Continue to turn the screw head 31 until the plug head 3 is tightened, thus sealing the oil filling hole 22. After tightening, the sealing ring 34 enters the sealing sleeve 33 and fits tightly with the sealing sleeve 33, and the sealing gasket 35 fits with the screw head 31. The sealing sleeve 33, sealing ring 34 and other structures form the first layer of sealing, and the sealing gasket 35 forms the second layer of sealing, which can improve the sealing performance of the oil filling hole 22 and effectively reduce the phenomenon of lubricating oil seeping out of the oil filling hole 22 when the gear rotates at high speed. When it is necessary to add oil to the oil reservoir 21, use a screwdriver to turn the screw head 31 to separate the plug head 3 from the oil filling hole 22, and then add lubricating oil into the oil reservoir 21 through the oil filling hole 22.

[0035] A connecting rope 36 is fixed inside the oil storage chamber 21, and the connecting rope 36 is fixedly connected to the sealing head 3.

[0036] After the plug head 3 is separated from the oil filling hole 22, the connecting rope 36 ensures that the plug head 3 is always connected to the gear body 11 and will not be lost due to careless placement.

[0037] An isolation net 4 is provided at the end of the oil supply channel 23 away from the oil storage chamber 21, and the isolation net 4 is fixedly connected to the teeth 11.

[0038] During gear use, the barrier mesh 4 can effectively reduce the entry of external dust into the oil supply channel 23, thereby reducing the condensation of dust on the inner wall of the oil supply channel 23 and preventing the oil from flowing out of the oil supply channel 23 smoothly, thus making it more conducive to the lubrication of the gear.

[0039] The surface of tooth 11 is provided with a wear-resistant layer, which is a hard chrome plating layer.

[0040] By applying a hard chrome plating to the surface of tooth 11, the wear resistance of tooth 11 can be improved, making tooth 11 less prone to wear during long-term use of the gear, thereby increasing the service life of the gear.

[0041] Working principle: Before using the gear, add an appropriate amount of lubricating oil into the oil reservoir 21 through the oil filling hole 22. After oil filling, connect the sealing head 3 to the oil filling hole 22, and connect the sealing ring 34 to the sealing sleeve 33. Then, use a screwdriver to turn the screw head 31, so that the sealing head 3 gradually enters the oil filling hole 22, and the sealing ring 34 gradually enters the sealing sleeve 33. Continue to turn the screw head 31 until the sealing head 3 is tightened, thus sealing the oil filling hole 22. After tightening, the sealing ring 34 enters the sealing sleeve 33 and fits tightly against the sealing sleeve 33, and the sealing gasket 35 fits against the screw head 31, completing the sealing of the oil filling hole 22; the mounting ring 12 is set inside the gear body 11. Installed on the drive shaft, it is used to mount gears. When the gears are working, as the gears rotate at high speed, the lubricating oil inside the oil reservoir 21 flows slowly out along the oil supply channel 23 under the action of centrifugal force and flows onto the teeth 11. When the teeth 11 come into contact with the teeth 11 of other gears, the lubricating oil serves to lubricate, reduce the friction of the gear components, thereby reducing abnormal noise of the gear components. In addition, the lubricating oil forms a damping effect between the teeth 11, thereby playing a role in shock absorption and making the gears run stably. When it is necessary to add oil to the oil reservoir 21, use a screwdriver to turn the screw head 31 to separate the plug head 3 from the oil filling hole 22, and then add lubricating oil into the oil reservoir 21 through the oil filling hole 22.
