Technical Field

[0001] The present invention relates to the technical field of deep groove ball bearings, and particularly to an integrated structure for wear resistance and corrosion resistance of a vehicle deep groove ball bearing. Background Technique

[0002] The deep groove ball bearing was originally called a single row radial ball bearing and is the most widely used rolling bearing. Its characteristics are small frictional resistance and high rotational speed. It can be used for parts that can bear radial loads or combined loads acting radially and axially at the same time, and can also be used for parts that bear axial loads, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machinery, tools, etc. Due to its good performance, it has gradually become a core transmission component of automobiles.

[0003] However, the existing vehicle deep groove ball bearings have the following deficiencies: During the use of vehicle deep groove ball bearings, the friction heat generated by the high-speed rotating balls and the raceways and cages is significant, resulting in a change in the viscosity of the grease, affecting the lubrication effect, aggravating part wear, and in the design of the sealing structure, the traditional contact seal has a large frictional resistance during high-speed rotation and is also prone to wear and aging problems, resulting in lubricating oil leakage or intrusion of external dust and water, affecting the corrosion resistance of the deep groove ball bearing.

[0004] Therefore, we have proposed an integrated structure for wear resistance and corrosion resistance of a vehicle deep groove ball bearing to solve the problems raised above. Summary of the Invention

The controller is used to establish a signal connection between the micro-viscosity sensor 204 and the micro-oil pump 202. The micro-viscosity sensor 204 is used to monitor the viscosity of the grease filled between the inner ring 101 and the outer ring 105, and the detected signal is sent to the controller. The controller is used to judge the threshold value. When the viscosity of the grease is greater than the set threshold value, the micro-oil pump 202 is automatically started. The micro-oil pump 202 is used to extract the lubricant and fill it between the inner ring 101 and the outer ring 105, ensuring the stable operation of the lubrication system, avoiding the influence of the change in the viscosity of the grease on the lubrication effect, improving the wear and corrosion resistance of the parts, prolonging the service life, and reducing the maintenance cost at the same time.

[0024] Embodiment 2, according to Figures 4 - 7As shown, the main body mechanism 1 includes an inner ring 101 and an outer ring 105. An outer groove 102 is formed on the outer surface wall of the inner ring 101. A set of steel balls 103 are slidably connected in the outer groove 102. A cage 104 is rotatably connected to the outer surface wall of the set of steel balls 103. An inner groove 106 is formed on the inner wall of the outer ring 105. The set of steel balls 103 are arranged inside the inner groove 106 and rotatably connected to the inner groove 106. 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 arranged inside the first sealing groove 107 and the second sealing groove 108. The first sealing ring 109 is arranged on the outer side of the cage 104 in a non-contact labyrinth sealing system, and the second sealing ring 110 is arranged on the outer side of the first sealing ring 109 in a lip seal system. A metal skeleton 111 is arranged on the outer side of the second sealing ring 110. A detection channel 112 and a replenishment hole 113 are formed through the inside of the outer ring 105. Nitride films 114 are arranged on the outer walls of the inner ring 101, the outer ring 105, and the steel balls 103. A rivet 115 is 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 through the rivet 115. The cage 104 has two upper and lower pieces, and the two upper and lower pieces are fixedly connected through the rivet 115. The radius of curvature of the inner groove 106 is greater than that of the outer groove 102, and a lubricating grease is filled between the inner groove 106 and the outer groove 102.

[0025] The effects achieved by the entire Embodiment 2 are as follows: For the above-mentioned components, by setting the inner ring 101 and the outer ring 105, an outer groove 102 is opened on the outer surface wall of the inner ring 101, and an inner groove 106 is opened on the inner wall of the outer ring 105. A set of steel balls 103 is arranged between the outer groove 102 and the inner groove 106, so that the steel balls 103 are rotationally connected to the inner ring 101 and the outer ring 105. The curvature radius of the inner groove 106 is set to be greater than that of the outer groove 102, reducing the edge stress concentration between the steel balls 103 and the grooves, reducing sliding friction, thereby reducing the wear amount. At the same time, the number of steel balls 103 is reduced, and large-diameter steel balls 103 are used to reduce the centrifugal force and wear, extending the service life of the deep groove ball bearing. A cage 104 is rotationally connected to the outer surface wall of the steel balls 103, and the cage 104 is set into an upper and lower two-piece structure and fixed by rivets 115. This design can improve the yield rate of bearing assembly and enhance the reparability. When one-sided cage 104 is damaged, it can be partially replaced, reducing the maintenance cost compared to the integral type; in the design of the sealing structure of the deep groove ball bearing, a multi-layer combined sealing system is adopted. By symmetrically opening two first sealing grooves 107 and second sealing grooves 108, a first sealing ring 109 and a second sealing ring 110 are respectively arranged inside the first sealing grooves 107 and second sealing grooves 108. 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, and the lip is designed with a serrated structure to enhance the dust and water prevention ability, avoiding the intrusion of external dust and water, thereby improving the corrosion resistance of the deep groove ball bearing. Then, a metal skeleton 111 is arranged outside 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 by rivets 115 to further improve the sealing effect; nitride films 114 are arranged on the outer walls of the inner ring 101, outer ring 105 and steel balls 103 in the components to improve the wear resistance and corrosion resistance of the core parts. Then, a detection channel 112 and a replenishment 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, improving the corrosion resistance while ensuring rigidity. Ceramic steel balls 103 are used to reduce the weight and frictional heat generation at the same time. Carbon fiber-reinforced nylon is used to make the cage 104, reducing the weight, improving the chemical corrosion resistance, and having its own lubricity, and being able to maintain the lubrication effect when the grease fails.

[0026] Embodiment 3, according to Figures 1 - 8As shown, the lubricating cylinder 201 is fixedly installed on the outer surface wall of the outer ring 105. The probe of the micro-viscosity sensor 204 is inserted into the interior of the detection channel 112. The oil supply pipe 203 is inserted into the interior of the replenishment hole 113. The micro-viscosity sensor 204 is used to detect the viscosity of the grease and send the detection signal to the controller. The controller determines the threshold to control the opening and closing of the micro-oil pump 202. The external connection pipe 205 is inserted into the interior of the through hole 209. A fixing nail 211 is inserted into the interior of the fixing hole 210. The fixing nail 211 is threadedly connected to the outer ring 105.

[0027] The effect achieved by the entire Embodiment 3 is as follows: For the components included above, by fixedly installing the lubricating cylinder 201 on the outer surface wall of the outer ring 105, the fixation of the lubricating cylinder 201 is realized. When connecting the main body mechanism 1 and the detection mechanism 2, by inserting a fixing nail 211 into the interior of the fixing hole 210 and using the threaded connection between the fixing nail 211 and the outer ring 105, the protective outer frame 208 is fixed on the outer surface wall of the outer ring 105. Then, the probe of the micro-viscosity sensor 204 provided in the detection mechanism 2 is inserted into the interior of the detection channel 112, and the oil supply pipe 203 is inserted into the interior of the replenishment hole 113. The controller is used to establish a signal connection between the micro-viscosity sensor 204 and the micro-oil pump 202. The micro-viscosity sensor 204 is used to monitor the viscosity state of the grease filled between the inner ring 101 and the outer ring 105, and send the detected signal to the controller. The controller determines the 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 is used to extract the lubricant and fill it between the inner ring 101 and the outer ring 105, ensuring the stable operation of the lubrication system, avoiding the influence of the change in the viscosity of the grease on the lubrication effect, improving the wear resistance and corrosion resistance of the parts, while extending the service life and reducing the maintenance cost.

[0028] The working principle of the entire device is as follows: When the structure of this automotive deep groove ball bearing is designed, it can be divided into a main body mechanism 1 and a detection mechanism 2. The main body mechanism 1 includes the main components of the deep groove ball bearing and is used to realize the main functional characteristics of the bearing. In addition, on the premise of ensuring the realization of the basic functions of the deep groove ball bearing, a detection mechanism 2 is added. The detection mechanism 2 is used to detect the viscosity state of the grease inside the deep groove ball bearing, perform intelligent monitoring on it, and timely replenish the lubricant into the deep groove ball bearing. This design is beneficial to improving the wear resistance of the deep groove ball bearing and extending its service life.

[0029] In the structural design of the main body mechanism 1 of this automotive deep groove ball bearing, by setting the inner ring 101 and the outer ring 105, an outer groove 102 is opened on the outer surface wall of the inner ring 101, and an inner groove 106 is opened on the inner wall of the outer ring 105. A set of steel balls 103 is arranged between the outer groove 102 and the inner groove 106, so that the steel balls 103 are rotationally connected to the inner ring 101 and the outer ring 105. The curvature radius of the inner groove 106 is set to be greater than that of the outer groove 102, reducing the edge stress concentration between the steel balls 103 and the grooves, reducing sliding friction, thereby reducing the wear amount. At the same time, the number of steel balls 103 is reduced, and large-diameter steel balls 103 are used to reduce the centrifugal force and wear, extending the service life of the deep groove ball bearing. A cage 104 is rotationally connected to the outer surface wall of the steel balls 103, and the cage 104 is set into an upper and lower two-piece structure and fixed by rivets 115. This design can improve the yield rate of bearing assembly and enhance the reparability. When one-sided cage 104 is damaged, it can be partially replaced, reducing the maintenance cost compared with the integral type; in the design of the sealing structure of the deep groove ball bearing, a multi-layer combined sealing system is adopted. By symmetrically opening two first sealing grooves 107 and second sealing grooves 108, a first sealing ring 109 and a second sealing ring 110 are respectively arranged inside the first sealing grooves 107 and second sealing grooves 108. 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, and the lip is designed with a serrated structure to enhance the dust and water protection ability, preventing external dust and water from invading, thereby improving the corrosion resistance of the deep groove ball bearing. Then a metal skeleton 111 is arranged outside 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 by rivets 115 to further improve the sealing effect; nitride films 114 are arranged on the outer walls of the inner ring 101, the outer ring 105 and the steel balls 103 in the components, improving the wear resistance and corrosion resistance of the core parts. Then detection channels 112 and replenishment holes 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, improving the corrosion resistance while ensuring rigidity. Ceramic steel balls 103 are adopted to reduce the weight and reduce frictional heat generation at the same time. Carbon fiber-reinforced nylon is used to make the cage 104, reducing the weight, improving the chemical corrosion resistance, and having its own lubricity, and being able to maintain the lubrication effect when the grease fails.

[0030] The detection mechanism 2 is added to the outer surface wall of the outer ring 105. Among them, the lubricating cylinders 201 are installed on the outer surface wall of the outer ring 105. A micro oil pump 202 is fixedly installed on the outer surface wall of the lubricating cylinder 201. The inlet end of the micro oil pump 202 is connected to the lubricating cylinder 201 through a pipeline. The outlet end of the micro oil pump 202 is fixedly communicated with a supplementary oil pipe 203. The micro oil pump 202 is used to extract the lubricant inside the lubricating cylinder 201 and supplement the lubricant into the bearing through the supplementary oil pipe 203. The outer surface wall of the lubricating cylinder 201 is fixedly communicated with an external connection pipe 205, which is convenient for regularly supplementing the lubricant into the lubricating cylinder 201. Under normal use conditions, a sealing plug 206 is snap-fitted inside the external connection pipe 205 to seal the lubricating cylinder 201 conveniently. An anti-corrosion coating 207 is provided on the outer surface wall of the sealing plug 206 to improve the corrosion resistance of the sealing plug 206 and avoid affecting the sealing effect. Then, a protective outer frame 208 is sleeved on the outer surface wall of the lubricating cylinder 201. Through holes 209 and fixing holes 210 are opened inside the protective outer frame 208 to protect the externally installed lubricating components. The external connection pipe 205 is arranged inside the through hole 209 and is communicated with the outside world.

[0031] When the two mechanisms are assembled, a fixing nail 211 is inserted into the fixing hole 210, and the fixing nail 211 is threadedly connected to the outer ring 105 to fix the protective outer frame 208 on the outer surface wall of the outer ring 105. Then, the probe of the micro viscosity sensor 204 provided in the detection mechanism 2 is inserted into the detection channel 112, and the supplementary oil pipe 203 is inserted into the supplementary hole 113. The controller is used to establish a signal connection between the micro viscosity sensor 204 and the micro oil pump 202. The micro viscosity sensor 204 is used to monitor the viscosity of the grease filled between the inner ring 101 and the outer ring 105, and the detected signal is sent to the controller. The controller is used to judge the threshold value. When the viscosity of the grease is greater than the set threshold value, the micro oil pump 202 is automatically started. The micro oil pump 202 is used to extract the lubricant and fill it between the inner ring 101 and the outer ring 105, ensuring the stable operation of the lubrication system, avoiding the influence of the change of grease viscosity on the lubrication effect, improving the wear-resistant and corrosion-resistant performance of the parts, prolonging the service life at the same time, and reducing the maintenance cost.
