Description

Technical Field

[0001] This invention relates to the field of deep groove ball bearing technology, specifically to an integrated structure for wear-resistant and corrosion-resistant deep groove ball bearings used in automobiles. Background Technology

[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used type of rolling bearing. They are characterized by low frictional resistance and high speed, making them suitable for components bearing radial loads or combined radial and axial loads, as well as axial loads. Examples include small-power electric motors, automotive and tractor gearboxes, machine tool gearboxes, and general machinery and tools. Due to their excellent performance, they have gradually become core transmission components in automobiles.

[0003] However, existing deep groove ball bearings for automobiles have the following shortcomings:

[0004] During use, the high-speed rotating balls generate significant frictional heat with the raceway and cage, causing changes in the viscosity of the grease, affecting lubrication, and accelerating wear of parts. In addition, the traditional contact seal design has high frictional resistance at high speeds, which can easily lead to wear and aging, resulting in lubricant leakage or the intrusion of external dust and water, affecting the corrosion resistance of the deep groove ball bearing.

[0005] Therefore, we propose an integrated wear-resistant and corrosion-resistant structure for automotive deep groove ball bearings to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated wear-resistant and corrosion-resistant structure for automotive deep groove ball bearings. By setting up a detection mechanism, a micro viscosity sensor probe is inserted inside the detection channel, and an oil replenishment pipe is inserted inside the replenishment hole. A controller establishes a signal connection between the micro viscosity sensor and a micro oil pump. The micro viscosity sensor monitors the viscosity of the lubricating grease and sends the detected signal to the controller. The controller determines a threshold; when the viscosity of the lubricating grease exceeds the set threshold, the micro oil pump automatically starts to replenish lubricant, reducing the viscosity and preventing excessively high grease viscosity from affecting lubrication. This design optimizes the lubrication structure of deep groove ball bearings, improves overall wear and corrosion resistance, extends service life, and reduces maintenance costs, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated wear-resistant and corrosion-resistant structure for automotive deep groove ball bearings, comprising a main body structure, wherein a detection mechanism for detecting the viscosity of the internal lubricating grease is provided on the outside of the main body structure.

[0008] The detection mechanism includes a lubrication cylinder and a miniature viscosity sensor. A miniature oil pump is fixedly installed on the outer wall of the lubrication cylinder. The inlet end of the miniature oil pump is connected to the lubrication cylinder through a pipe, and the outlet end of the miniature oil pump is fixedly connected to an oil replenishment pipe. The miniature viscosity sensor establishes a signal connection with the miniature oil pump through a controller. An external connecting pipe is fixedly connected to the outer wall of the lubrication cylinder, and a sealing plug is snapped into the end of the external connecting pipe. The outer wall of the sealing plug is provided with an anti-corrosion coating. A protective frame is provided on the outer wall of the lubrication cylinder, and through holes and fixing holes are respectively opened inside the protective frame.

[0009] Preferably, the main body mechanism includes an inner ring and an outer ring. The outer wall of the inner ring has an outer groove. A set of steel balls is slidably connected in the outer groove. A retainer is rotatably connected to the outer wall of the set of steel balls.

[0010] Preferably, the inner wall of the outer ring has an inner channel, and a set of steel balls is disposed inside the inner channel and rotatably connected to the inner channel.

[0011] Preferably, the outer ring has two sets of first sealing grooves and second sealing grooves respectively inside, and the two sets of first sealing grooves and second sealing grooves are symmetrically distributed.

[0012] Preferably, a first sealing ring and a second sealing ring are respectively provided inside the first sealing groove and the second sealing groove. The first sealing ring is provided on the outside of the cage using a non-contact labyrinth sealing system, and the second sealing ring is provided on the outside of the first sealing ring using a lip sealing system.

[0013] Preferably, a metal frame is provided on the outer side of the second sealing ring, and a detection channel and a replenishment hole are provided through the inner side of the outer ring.

[0014] Preferably, the inner ring, outer ring, and outer wall of the steel ball are all provided with a nitrided film, rivets are inserted inside the metal frame, the inner ring and outer ring are riveted to the metal frame by rivets, and the retainer is provided with upper and lower pieces, which are fixedly connected by rivets.

[0015] Preferably, the radius of curvature of the inner channel is greater than that of the outer channel, and the space between the inner and outer channels is filled with grease.

[0016] Preferably, the lubrication cylinder is fixedly installed on the outer wall of the outer ring, the probe of the micro viscosity sensor is inserted inside the detection channel, the oil replenishment pipe is inserted inside the replenishment hole, the micro viscosity sensor is used to detect the viscosity of the lubricating grease and send the detection signal to the controller, and the controller determines the threshold to control the start and stop of the micro oil pump.

[0017] Preferably, the external connecting pipe is inserted into the through hole, and a fixing pin is inserted into the fixing hole, the fixing pin being threaded to the outer ring.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention, by setting up a detection mechanism, inserts the probe of a micro viscosity sensor inside the detection channel and the oil replenishment pipe inside the replenishment hole. A controller establishes a signal connection between the micro viscosity sensor and the micro oil pump. The micro viscosity sensor monitors the viscosity of the grease and sends the detected signal to the controller. The controller determines a threshold; when the grease viscosity exceeds the set threshold, the micro oil pump automatically starts to replenish lubricant, reducing the grease viscosity and preventing excessively high grease viscosity from affecting lubrication. This design optimizes the lubrication structure of deep groove ball bearings, improves overall wear and corrosion resistance, extends service life, and reduces maintenance costs.

[0020] 2. In this invention, the equipment reduces stress concentration at the edges of the steel balls and the grooves by setting the radius of curvature of the inner groove to be larger than that of the outer groove, thereby reducing sliding friction and wear. It employs a two-piece cage, secured with rivets, improving the yield rate of bearing assembly and enhancing repairability. In case of damage to one side of the cage, partial replacement is possible, reducing maintenance costs compared to a single-piece design. Simultaneously, a multi-layer combined sealing system is used. Two symmetrical first and second sealing grooves are created, with first and second sealing rings respectively placed inside each groove. The first sealing ring uses a non-contact labyrinth seal to reduce frictional heat generation, while the second sealing ring uses a lip seal with a serrated lip design to enhance dust and water resistance, preventing external dust and water intrusion and thus improving the corrosion resistance of the deep groove ball bearing.

[0032] Example 1, according to Figure 8As shown, the detection mechanism 2 includes a lubrication cylinder 201 and a micro viscosity sensor 204. A micro oil pump 202 is fixedly installed on the outer wall of the lubrication cylinder 201. The inlet end of the micro oil pump 202 is connected to the lubrication cylinder 201 through a pipe. The outlet end of the micro oil pump 202 is fixedly connected to an oil replenishment pipe 203. The micro viscosity sensor 204 establishes a signal connection with the micro oil pump 202 through a controller. An external connecting pipe 205 is fixedly connected to the outer wall of the lubrication cylinder 201. A sealing plug 206 is snapped into the end of the external connecting pipe 205.

The interior of the protective frame 208 is provided with a through hole 209 and a fixing hole 210.

[0033] The overall effect of Embodiment 1 is as follows: The components included are installed on the outer wall of the outer ring 105 via lubrication cylinders 201.

The inlet end of the micro oil pump 202 is connected to the lubrication cylinder 201 via a pipe, and the outlet end of the micro oil pump 202 is fixedly connected to the oil replenishment pipe 203.

The outer wall of the lubrication cylinder 201 is fixedly connected to the external connecting pipe 205, which facilitates the periodic replenishment of lubricant to the inside of the lubrication cylinder 201. Under normal use, the sealing plug 206 is snapped into the inside of the external connecting pipe 205 to facilitate sealing the lubrication cylinder 201. The outer wall of the sealing plug 206 is provided with an anti-corrosion coating 207 to improve the corrosion resistance of the sealing plug 206 and avoid affecting the sealing effect. Then, the protective frame 208 is fitted onto the outer wall of the lubrication cylinder 201, and the inside of the protective frame 208... The system includes a through hole 209 and a fixing hole 210 to protect the external lubrication components. The external connecting pipe 205 is located inside the through hole 209 and connects to the outside. In use, the probe of the micro viscosity sensor 204 is inserted into the detection channel 112, and the oil replenishment pipe 203 is inserted into the replenishment hole 113. The controller establishes a signal connection between the micro viscosity sensor 204 and the micro oil pump 202. The micro viscosity sensor 204 monitors the viscosity of the grease filling between the inner ring 101 and the outer ring 105 and sends the detected signal to the controller. The controller determines a threshold. When the viscosity of the grease is greater than the set threshold, the micro oil pump 202 is automatically started. The micro oil pump 202 draws lubricant and fills the space between the inner ring 101 and the outer ring 105, ensuring the stable operation of the lubrication system, avoiding the impact of grease viscosity changes on the lubrication effect, improving the wear resistance and corrosion resistance of the parts, extending their service life, and reducing maintenance costs.

[0034] Example 2, according to Figures 4-7As shown, the main body 1 includes an inner ring 101 and an outer ring 105. The outer wall of the inner ring 101 has an outer groove 102, and a set of steel balls 103 are slidably connected within the outer groove 102. A retainer 104 is rotatably connected to the outer wall of the set of steel balls 103. The inner wall of the outer ring 105 has an inner groove 106, and the set of steel balls 103 is disposed inside the inner groove 106 and rotatably connected to it. Two sets of first sealing grooves 107 and second sealing grooves 108 are respectively formed inside the outer ring 105, and the two sets of first sealing grooves 107 and second sealing grooves 108 are symmetrically distributed. A first sealing ring 109 and a second sealing ring 110 are respectively disposed inside the first sealing groove 107 and the second sealing groove 108. The first sealing ring 109 uses a non-contact labyrinth sealing system. The first sealing ring 109 is located on the outside of the retainer 104. The second sealing ring 110 is located on the outside of the first sealing ring 109 using a lip sealing system. A metal skeleton 111 is provided on the outside of the second sealing ring 110. A detection channel 112 and a supplement hole 113 are provided through the inside of the outer ring 105. Nitrided films 114 are provided on the outer walls of the inner ring 101, the outer ring 105 and the steel ball 103. Rivets 115 are inserted into the inside of the metal skeleton 111. The inner ring 101 and the outer ring 105 are riveted to the metal skeleton 111 by the rivets 115. The retainer 104 is provided with two pieces, upper and lower, which are fixedly connected by the rivets 115. The radius of curvature of the inner channel 106 is larger than that of the outer channel 102. The space between the inner channel 106 and the outer channel 102 is filled with grease.

[0035] The overall effect of Embodiment 2 is as follows: The aforementioned components, by setting an inner ring 101 and an outer ring 105, have an outer groove 102 formed on the outer wall of the inner ring 101 and an inner groove 106 formed on the inner wall of the outer ring 105. A set of steel balls 103 are placed between the outer groove 102 and the inner groove 106, allowing the steel balls 103 to be rotatably connected to the inner ring 101 and the outer ring 105. The radius of curvature of the inner groove 106 is set to be larger than that of the outer groove 102, reducing stress concentration at the edge of the steel balls 103 and the groove, reducing sliding friction, thereby reducing wear. Simultaneously, the number of steel balls 103 is reduced, and a large straight... The use of steel balls 103 reduces centrifugal force and wear, extending the service life of the deep groove ball bearing. A cage 104 is rotatably connected to the outer wall of the steel balls 103, and the cage 104 is designed as a two-piece structure, secured with rivets 115. This design improves the bearing assembly yield and enhances repairability; if one side of the cage 104 is damaged, it can be partially replaced, reducing maintenance costs compared to a single-piece design. The sealing structure of the deep groove ball bearing employs a multi-layer combined sealing system, using two symmetrically spaced first sealing grooves 107 and second sealing grooves 108. The inner ring 108 is internally equipped with a first sealing ring 109 and a second sealing ring 110. The first sealing ring 109 adopts a non-contact labyrinth seal, which reduces frictional heat generation and is suitable for high-speed rotation. The second sealing ring 110 adopts a lip seal with a serrated structure on the lip edge to enhance dust and water resistance and prevent external dust and water from entering, thereby improving the corrosion resistance of the deep groove ball bearing. A metal skeleton 111 is then provided on the outside of the second sealing ring 110, and the metal skeleton 111 is fixed to both ends of the inner ring 101 and the outer ring 105 using rivets 115 to further improve the sealing effect. The inner ring 109 of the component is also included. 1. A nitrided film 114 is provided on the outer wall of both the outer ring 105 and the steel ball 103 to improve the wear resistance and corrosion resistance of the core components. Then, a detection channel 112 and a supplementary hole 113 are respectively opened inside the outer ring 105 for connecting the detection mechanism 2. In terms of material selection, stainless steel is used to make the inner ring 101 and the outer ring 105 to ensure rigidity and improve corrosion resistance. Ceramic steel ball 103 is used to reduce weight and reduce frictional heat generation. Carbon fiber reinforced nylon is used to make the cage 104 to reduce weight, improve chemical corrosion resistance, and it has its own lubrication properties, so that it can maintain the lubrication effect when the grease fails.

[0036] Example 3, according to Figures 1-8As shown, the lubrication cylinder 201 is fixedly installed on the outer wall of the outer ring 105. The probe of the micro viscosity sensor 204 is inserted inside the detection channel 112. The oil replenishment pipe 203 is inserted inside the replenishment hole 113.

The controller determines the threshold and controls the opening and closing of the micro oil pump 202. The external connecting pipe 205 is inserted inside the through hole 209. The fixing pin 211 is inserted inside the fixing hole 210 and is threadedly connected to the outer ring 105.

[0037] The overall effect of embodiment 3 is as follows: The components described above are fixed by fixing the lubricating cylinder 201 to the outer wall of the outer ring 105. When connecting the main body mechanism 1 and the detection mechanism 2, fixing pins 211 are inserted into the fixing hole 210, and the fixing pins 211 are threadedly connected to the outer ring 105 to fix the protective frame 208 to the outer wall of the outer ring 105. The probe of the miniature viscosity sensor 204 in the detection mechanism 2 is then inserted into the detection channel 112, and the oil replenishment pipe 203 is inserted into the replenishment hole 113. The controller is then used to... A micro viscosity sensor 204 is connected to a micro oil pump 202. The micro viscosity sensor 204 monitors the viscosity of the grease filling the space between the inner ring 101 and the outer ring 105. The detected signal is sent to the controller, which determines a threshold. When the viscosity of the grease is greater than the set threshold, the micro oil pump 202 is automatically started. The micro oil pump 202 draws lubricant and fills the space between the inner ring 101 and the outer ring 105, ensuring the stable operation of the lubrication system, avoiding the impact of grease viscosity changes on the lubrication effect, improving the wear resistance and corrosion resistance of parts, extending service life, and reducing maintenance costs.

[0038] The working principle of the entire device is as follows: The automotive deep groove ball bearing can be divided into a main body 1 and a detection mechanism 2 in its structural design. The main body 1 includes the main components of the deep groove ball bearing, which are used to realize the main functional characteristics of the bearing. In addition, the detection mechanism 2 is added on the premise of ensuring that the basic functions of the deep groove ball bearing are realized. The detection mechanism 2 is used to detect the viscosity of the grease inside the deep groove ball bearing, and to intelligently monitor it and replenish the lubricant inside the deep groove ball bearing in a timely manner. This design is conducive to improving the wear resistance of the deep groove ball bearing and extending its service life.

[0039] The main structure 1 of this automotive deep groove ball bearing is designed with an inner ring 101 and an outer ring 105. An outer groove 102 is formed on the outer wall of the inner ring 101, and an inner groove 106 is formed on the inner wall of the outer ring 105. A set of steel balls 103 are positioned between the outer groove 102 and the inner groove 106, allowing the steel balls 103 to rotate with both the inner and outer rings 101 and 105. The radius of curvature of the inner groove 106 is larger than that of the outer groove 102, reducing stress concentration at the edges of the steel balls 103 and the grooves, thus reducing sliding friction and wear. This design also reduces the number of steel balls 103 and utilizes a large straight... The use of steel balls 103 reduces centrifugal force and wear, extending the service life of the deep groove ball bearing. A cage 104 is rotatably connected to the outer wall of the steel balls 103, and the cage 104 is designed as a two-piece structure, secured with rivets 115. This design improves the bearing assembly yield and enhances repairability; if one side of the cage 104 is damaged, it can be partially replaced, reducing maintenance costs compared to a single-piece design. The sealing structure of the deep groove ball bearing employs a multi-layer combined sealing system, using two symmetrically spaced first sealing grooves 107 and second sealing grooves 108. The inner ring 108 is internally equipped with a first sealing ring 109 and a second sealing ring 110. The first sealing ring 109 adopts a non-contact labyrinth seal, which reduces frictional heat generation and is suitable for high-speed rotation. The second sealing ring 110 adopts a lip seal with a serrated structure on the lip edge to enhance dust and water resistance and prevent external dust and water from entering, thereby improving the corrosion resistance of the deep groove ball bearing. A metal skeleton 111 is then provided on the outside of the second sealing ring 110, and the metal skeleton 111 is fixed to both ends of the inner ring 101 and the outer ring 105 using rivets 115 to further improve the sealing effect. The inner ring 109 of the component is also included. 1. A nitrided film 114 is provided on the outer wall of both the outer ring 105 and the steel ball 103 to improve the wear resistance and corrosion resistance of the core components. Then, a detection channel 112 and a supplementary hole 113 are respectively opened inside the outer ring 105 for connecting the detection mechanism 2. In terms of material selection, stainless steel is used to make the inner ring 101 and the outer ring 105 to ensure rigidity and improve corrosion resistance. Ceramic steel ball 103 is used to reduce weight and reduce frictional heat generation. Carbon fiber reinforced nylon is used to make the cage 104 to reduce weight, improve chemical corrosion resistance, and it has its own lubrication properties, so that it can maintain the lubrication effect when the grease fails.

[0040] The testing mechanism 2 is added to the outer wall of the outer ring 105. Lubrication cylinders 201 are installed on the outer wall of the outer ring 105. A miniature oil pump 202 is fixedly installed on the outer wall of the lubrication cylinders 201. The inlet end of the miniature oil pump 202 is connected to the lubrication cylinders 201 via a pipe, and the outlet end of the miniature oil pump 202 is fixedly connected to the oil replenishment pipe 203. The miniature oil pump 202 draws lubricant from inside the lubrication cylinders 201 and replenishes the bearing through the oil replenishment pipe 203. The outer wall of the lubrication cylinders 201 is fixedly connected to an external connecting pipe 205 for periodic replenishment of the lubrication cylinders. The lubricant inside the lubrication cylinder 201 is replenished. Under normal use, the sealing plug 206 is snapped into the inside of the external connecting pipe 205 to facilitate sealing of the lubrication cylinder 201. The outer wall of the sealing plug 206 is provided with an anti-corrosion coating 207 to improve the corrosion resistance of the sealing plug 206 and avoid affecting the sealing effect. Then, the protective frame 208 is fitted onto the outer wall of the lubrication cylinder 201. The protective frame 208 has a through hole 209 and a fixing hole 210 inside to protect the external lubrication components. The external connecting pipe 205 is set inside the through hole 209 and is connected to the outside.

[0041] During assembly, the two mechanisms are fixed by inserting fixing pins 211 into the fixing holes 210 and threading them onto the outer ring 105. The protective frame 208 is then fixed to the outer wall of the outer ring 105. The probe of the micro viscosity sensor 204 in the detection mechanism 2 is inserted into the detection channel 112, and the oil replenishment pipe 203 is inserted into the replenishment hole 113. The controller establishes a signal connection between the micro viscosity sensor 204 and the micro oil pump 202. The micro viscosity sensor 204 monitors the viscosity of the grease filling between the inner ring 101 and the outer ring 105 and sends the detected signal to the controller. The controller determines a threshold. When the viscosity of the grease is greater than the set threshold, the micro oil pump 202 is automatically started. The micro oil pump 202 draws lubricant and fills the space between the inner ring 101 and the outer ring 105, ensuring the stable operation of the lubrication system, avoiding the impact of grease viscosity changes on the lubrication effect, improving the wear and corrosion resistance of the parts, extending their service life, and reducing maintenance costs.
