[0002] The primary function of the drive axle bearing seat is to provide a precise installation position and stable support for the bearing. The bearing is installed in the bearing seat, and the load borne by the bearing is transmitted to the vehicle frame or bridge housing and other structures through the seat body. For example, in the automobile drive axle, when the vehicle is driving, the rotation of the wheel is transmitted to the drive axle main reducer through the half shaft. The bearing of the main reducer is installed in the bearing seat. The bearing seat bears the radial and axial loads from the main reducer to ensure the normal operation of the main reducer. Among them, the drive axle bearing seat of the electric loader usually has a compact structure.

A rotating rod 42 is rotatably installed on the inner wall of the mounting cover 2, and a terminal is provided at one end of the sliding rod 41 located outside the mounting cover 2. One end of the rotating rod 42 is connected to the sliding rod 41 through a sliding hinge, and the other end of the rotating rod 42 is connected to the sliding seat 43 through a sliding hinge. The terminal of the sliding rod 41 is knocked to the left with a rubber hammer. When the sliding rod 41 moves to the left, the sliding seat 43 can be driven to move to the right through the rotating rod 42 by the lever principle. When the sliding seat 43 moves to the right, the bearing can be pushed out of the housing 1 to the right, which is convenient for the staff to disassemble and reduce The operation steps of disassembling the shell 1 are omitted; the inner wall of the shell 1 is slidably connected with a protrusion 45, the bottom of the protrusion 45 is connected with a pressure block 46, and the bottom surface of the slide rod 41 is connected with an inclined block 44. When the slide rod 41 moves, it drives the inclined block 44 to move, and the inclined block 44 slides in contact with the top of the protrusion 45. The inclined block 44 squeezes the protrusion 45 downward through its inclined surface, and the protrusion 45 drives the pressure block 46 to move downward. The pressure block 46 is slidably connected to the inner wall of the shell 1, and a plurality of rubber strips are arranged at the bottom of the pressure block 46. When the pressure block 46 moves into place, the plurality of rubber strips at the bottom of the pressure block 46 tightly press against the outer wall of the bearing, and there is a large friction between the plurality of rubber strips and the outer wall of the bearing.

By setting the pressing block 46, when the bearing is installed, the pressing block 46 can be tightly pressed against the bearing, thereby improving the stability of the bearing and preventing the outer wall of the bearing from rotating in the housing 1.

[0023] For further information, see Figure 6 - Fig.12The anti-leakage mechanism 5 is used to prevent the grease in the housing 1 from overflowing. The anti-leakage mechanism 5 includes a fixed ring 51, which is installed in the annular groove 3. A rotating ring 52 is rotatably connected to the fixed ring 51. The rotating ring 52 is provided with a plurality of inclined grooves, and the fixed ring 51 is provided with a plurality of straight grooves. Sliding shafts 54 are respectively slidably connected between the plurality of inclined grooves of the rotating ring 52 and the plurality of straight grooves on the fixed ring 51. The outer walls of the plurality of sliding shafts 54 are respectively connected with blades 53. The plurality of blades 53 are arranged in a circular array with the center of the rotating ring 52 as the center of the circle. Adjacent blades 53 are in sliding contact with each other. A gap is provided between the inner sides of the rotating ring 52 and the fixed ring 51. The plurality of blades 53 are located between the rotating ring 52 and the fixed ring 51. When the rotating ring 52 rotates clockwise, the multiple sliding shafts 54 are moved through the multiple inclined grooves above the multiple sliding shafts 54, so that the multiple sliding shafts 54 slide toward the center on the multiple straight grooves of the fixed ring 51. When the sliding shafts 54 move, the blades 53 are driven to move, so that the multiple blades 53 gradually gather together when following the sliding of the multiple sliding shafts 54. The outer wall of the rotating ring 52 is connected with a lever 55, and the end of the sliding rod 41 away from the end is connected with a groove plate 56, and the groove plate 56 is provided with an inclined groove. The lever 55 is slidably connected with the inclined groove of the groove plate 56. When the groove plate 56 moves to the left, the lever 55 is driven to move to the right through the inclined groove. When the lever 55 moves backward, it drives the rotating ring 52 to rotate clockwise. After the multiple blades 53 gather together, a plane is formed. After the shaft and the bearing are disassembled, the grease in the grease chamber of the housing 1 is blocked by a plurality of blades 53, so that the grease can be prevented from overflowing to the right, thereby increasing the cleaning work of the user; the leakage prevention mechanism 5 also includes a mounting ring 57, which is rotatably mounted inside the housing 1, and a plurality of scraper strips 58 are mounted on the mounting ring 57; a side of the fixed ring 51 away from the rotating ring 52 is rotatably connected to a gear 510, and an end of the gear 510 away from the fixed ring 51 is connected to a bevel gear rod 511; an outer wall of the rotating ring 52 close to the fixed ring 51 is connected to a residual tooth ring 59; an outer wall of the mounting ring 57 is provided with a tooth groove 512, which meshes with the gear 510, and a plurality of teeth are provided in the tooth groove 512. The multiple teeth of 512 mesh with the bevel gear rod 511. When the residual tooth ring 59 rotates, the bevel gear rod 511 is driven to rotate through the gear 510. The bevel gear rod 511 drives the mounting ring 57 to rotate through the multiple teeth in the tooth groove 512. When the multiple scraping strips 58 move, they all slide in contact with the inner wall of the shell 1. When the multiple scraping strips 58 rotate, they scrape the inner wall of the grease chamber of the shell 1. Since the grease on the inner wall of the chamber is far away from the rotating shaft, after long-term use, the grease on the inner wall of the chamber may clump due to long-term stationary. The scraping of the multiple scraping strips 58 can scrape the grease that has been attached to the inner wall of the chamber for a long time, and at the same time play the role of stirring the grease, thereby reducing the possibility of grease agglomeration.Through the setting of the anti-leakage mechanism 5, when the user disassembles the bearing, the multiple blades 53 can gather toward the center of the fixing ring 51 to form a plane, which plays a temporary sealing role, preventing the grease in the housing 1 from losing the barrier and overflowing to the right after the shaft and the bearing are disassembled, which increases the user's operation of cleaning and replenishing the grease; through the setting of the multiple scraping strips 58, when the bearing is replaced, the multiple scraping strips 58 can rotate to scrape the grease attached to the inner wall of the grease chamber of the housing 1, and at the same time play the role of stirring the grease, so as to avoid the grease on the inner wall of the chamber from increasing the probability of agglomeration due to long-term static. ;

[0024] Further, see Fig.13 - Fig.14 The sampling mechanism 6 is used to observe the state of the grease after the bearing is replaced. The sampling mechanism 6 includes a hollow column 61, which is installed on the housing 1 and the mounting cover 2. A screw cap 62 is installed on the top of the hollow column 61. A sampling tube 63 is slidably connected to the inner wall of the hollow column 61. A check ring 65 is connected to the inner wall of the hollow column 61. The check ring 65 is located below the sampling tube 63. A long groove is provided on the hollow column 61. A connecting piece is provided on the outer wall of the sampling tube 63. The sampling tube 63 The connecting piece is slidably connected with the long groove of the hollow column 61, the end of the groove plate 56 away from the sliding rod 41 is connected to the push rod 67, the end of the push rod 67 away from the groove plate 56 is hinged with a connecting rod 66, and the end of the connecting rod 66 away from the push rod 67 is hinged to the connecting piece of the sampling tube 63. The sampling tube 63 and the check ring 65 are both hollow. The inner walls of the sampling tube 63 and the check ring 65 are respectively provided with check valves. The one-way valves in the sampling tube 63 and the check ring 65 can only allow the grease to flow upward. When the sampling tube 63 moves upward, the grease below the check ring 65 can be drawn to between the check ring 65 and the sampling tube 63. When the sampling tube 63 is reset downward, the grease between it and the check ring 65 is squeezed to the top of the sampling tube 63 through its own inner wall. The bottom of the sampling tube 63 is connected to a baffle 64, which is slidably connected to the inner wall of the hollow column 61. The outer wall of the baffle 64 and the sampling tube 63 always blocks the long groove of the hollow column 61 to achieve a sealing effect. After the user twists off the rotary cover 62, the grease above the sampling tube 63 can be taken out, so as to distinguish the quality of the grease inside the shell 1 and decide whether to replace the grease. Through the setting of the sampling mechanism 6, after the user replaces the bearing, the sampling tube 63 cooperates with the check ring 65 to draw a part of the grease in the shell 1 to the top of the sampling tube 63. After the user opens the rotary cover 62, it can be evaluated whether the grease in the shell 1 needs to be replaced, thereby achieving the effect of facilitating the user to observe the state of the grease in the shell 1.

[0025] With the above structure, the working principle of this case is that the bearing is installed on the right inner wall of the housing 1, a connecting flange is provided on the left side of the housing 1 to connect with the drive axle, a grease chamber is provided on the left inner wall of the housing 1 to fill with grease, the bearing is inserted into the right inner wall of the housing 1 when installed, and the bearing abuts against the sliding seat 43, the left side of the sliding seat 43 abuts against a convex ring provided on the inner wall of the housing 1, and a protective cover that is easy to disassemble is provided on the right side of the housing 1 to protect the bearing and prevent dust. When the bearing needs to be disassembled, the rotating shaft and the protective cover are removed, and the end of the slide rod 41 is knocked to the left with a rubber hammer to make the slide rod 41 When the sliding bar 41 slides to the left in the installation cover 2, the rotating bar 42 is driven to rotate when the sliding bar 41 slides to the left, and the other end of the rotating bar 42 drives the sliding seat 43 to slide to the right, so that when the sliding bar 41 moves to the left, the sliding seat 43 can be driven to move to the right through the rotating bar 42 by the lever principle, and when the sliding seat 43 moves to the right, the bearing can be pushed out of the housing 1 to the right, which is convenient for the staff to disassemble and reduces the operation steps of disassembling the housing 1. After replacing the new bearing, after inserting the bearing into the housing 1, the bearing is knocked into the housing 1 with a rubber hammer, and the bearing drives the sliding seat 43 to move to the left, and the sliding seat 43 drives the rotating bar 42 to drive the sliding seat 43 to the right by the lever principle. The slide bar 41 moves to the right to reset, and the movement of the slide bar 41 drives the inclined surface block 44 to move. When the inclined surface block 44 is about to move to the rightmost position, it contacts the protrusion 45. After that, the inclined surface block 44 squeezes the protrusion 45 downward through its inclined surface, and the protrusion 45 drives the pressing block 46 to move downward. When the pressing block 46 moves into place, the multiple rubber strips at the bottom of the pressing block 46 tightly press against the outer wall of the bearing. There is a large friction between the multiple rubber strips and the outer wall of the bearing, so that the pressing block 46 can play a role in fixing the bearing, preventing the bearing from rotating in the housing 1, and enhancing the stability of the bearing. When disassembling the bearing, the slide bar 41 drives The inclined block 44 slides to the left, and after the inclined block 44 is out of contact with the protrusion 45, the pressure block 46 is reset by the elastic force of the spring, so that the pressure block 46 and the multiple rubber strips are out of contact with the bearing, and the removal of the bearing is not affected; by the setting of the disassembly mechanism 4, when the slide bar 41 moves to the left, the sliding seat 43 can be used to push the bearing out, and the user can remove the bearing by knocking on the slide bar 41, which is convenient to operate and has high replacement efficiency; by the setting of the pressure block 46, when the bearing is installed, the pressure block 46 can be tightly against the bearing, thereby improving the stability of the bearing and preventing the outer wall of the bearing from rotating in the housing 1.

[0026] When the slide bar 41 moves to the left, it drives the slot plate 56 to move to the left. When the slot plate 56 moves to the left, it drives the lever 55 to move to the right through the inclined slot. When the lever 55 moves backward, it drives the rotating ring 52 to rotate clockwise. When the rotating ring 52 rotates clockwise, it drives the multiple sliding shafts 54 through the multiple inclined slots above it, so that the multiple sliding shafts 54 slide toward the center on the multiple straight slots of the fixed ring 51. When the sliding shaft 54 ​​moves, it drives the blades 53 to move. Since the multiple blades 53 slide and contact each other, the multiple blades 53 gradually gather together when sliding with the multiple sliding shafts 54, so that the circular holes formed between the multiple blades 53 gradually shrink. Figure 8 Before the plurality of blades 53 are gathered together, Fig.10 After the multiple blades 53 are gathered together, the multiple blades 53 form a plane. After the shaft and the bearing are disassembled, the grease in the grease chamber of the shell 1 is blocked by the multiple blades 53, which can prevent the grease from overflowing to the right, increasing the user's cleaning work; when the rotating ring 52 rotates, it drives the residual tooth ring 59 to rotate, and when the residual tooth ring 59 rotates, it drives the bevel gear rod 511 to rotate through the gear 510, and the bevel gear rod 511 drives the installation ring 57 to rotate through the multiple teeth in the tooth groove 512, and the installation ring 57 drives the multiple scraping strips 58 to rotate. When the multiple scraping strips 58 rotate, they scrape the inner wall of the grease chamber of the shell 1. Since the grease on the inner wall of the chamber is far from the shaft, after long-term use, the grease on the inner wall of the chamber may clump due to long-term stillness. , through the scraping of multiple scraping strips 58, the grease that has been attached to the inner wall of the chamber for a long time can be scraped off, and at the same time, the grease can be stirred to reduce the possibility of grease agglomeration; through the setting of the leak-proof mechanism 5, when the user removes the bearing, the multiple blades 53 can gather toward the center of the fixing ring 51 to form a plane, which plays a temporary sealing role, and prevents the grease in the housing 1 from losing its obstruction and overflowing to the right after the shaft and the bearing are disassembled, thereby increasing the user's cleaning and grease replenishment operations; through the setting of multiple scraping strips 58, when replacing the bearing, the multiple scraping strips 58 can scrape the grease attached to the inner wall of the grease chamber of the housing 1 by rotating, and at the same time, the grease can be stirred to prevent the grease on the inner wall of the chamber from increasing the probability of agglomeration due to long-term stationary state.

[0027] The housing 1 is provided with a grease discharge port and a grease injection port for discharging and adding grease. When the groove plate 56 moves to the left, the groove plate 56 drives the push rod 67 to move to the left. Since the sampling tube 63 and its connecting parts can only move up and down in the hollow column 61, the push rod 67 drives the sampling tube 63 to move upward through the connecting rod 66 when it moves to the left. The one-way valve in the sampling tube 63 and the check ring 65 can only allow the grease to flow upward. The check ring 65 is located below the grease chamber. Therefore, when the sampling tube 63 moves upward, the grease below the check ring 65 can be drawn to between the check ring 65 and the sampling tube 63. When the push rod 67 follows the groove plate 56 to reset to the right, the push rod 67 drives the sampling tube 63 to reset downward through the connecting rod 66. When the sampling tube 63 resets downward The grease between it and the check ring 65 is squeezed to the top of the sampling tube 63 through its own inner wall. When the sampling tube 63 moves, the baffle 64 and the outer wall of the sampling tube 63 always block the long groove of the hollow column 61 to achieve a sealing effect. After the user unscrews the screw cap 62, the grease on the top of the sampling tube 63 can be taken out, so as to distinguish the quality of the grease inside the shell 1 and decide whether to replace the grease. Through the setting of the sampling mechanism 6, after the user replaces the bearing, the sampling tube 63 cooperates with the check ring 65 to extract a part of the grease in the shell 1 to the top of the sampling tube 63. After the user opens the screw cap 62, it can be evaluated whether the grease in the shell 1 needs to be replaced, thereby achieving the effect of facilitating the user to observe the state of the grease in the shell 1.

[0028] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
