Description

Technical Field

[0001] The invention relates to the technical field of bearings, and more particularly to an anti-loosening and stable rotating wheel hub bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure rotation accuracy. Bearings reduce friction losses and improve mechanical efficiency by converting sliding friction into rolling friction. Wheel hub bearings are mainly used in automobiles. Their main function is to carry weight and provide precise guidance for the rotation of the wheel hub. Wheel hub bearings not only need to bear axial loads, but also radial loads. They are widely used in various automobiles, especially in sedans. Due to their excellent performance and low maintenance requirements, wheel hub bearing units are also gradually expanding in trucks.

[0003] Existing bearings usually include an inner ring, an outer ring, rolling elements, a retaining frame and other parts. However, when a wheel hub bearing is in use, it is usually necessary to fix the bearing sleeve to a flange. At the same time, because the bearing is fixed on the flange, when the bearing is damaged, the flange may not be damaged and can continue to be used. However, because the bearing and the flange are fixedly connected, the entire wheel hub bearing needs to be replaced after the bearing is damaged, and the flange cannot be recycled, which reduces the practicality of the wheel hub bearing.

[0042] When in use, firstly, two groups of rolling elements 24 are placed on both sides of the inner part of the outer ring 21 respectively, and then the No. 1 inner ring 22 and the No. 2 inner ring 23 are moved from both sides of the outer ring 21 to the inner part of the outer ring 21, so that the No. 1 inner ring 22 and the No. 2 inner ring 23 become a complete inner ring, thereby forming a bearing body 2, and then the bearing body 2 is sleeved and fixed to the outer cylindrical surface of one side of the flange 1, so as to form a complete hub bearing.

[0047] In the above embodiment, the positioning rod 38 is inserted into the positioning hole 34, and then the No. 1 clamping block 314 is driven to be inserted into the No. 1 clamping groove 39, so that the positioning rod 38 is fixed in the positioning hole 34, thereby fixing the bearing body 2 on the flange 1, and then the No. 1 slide plate 36 can be pushed to move to the outside of the mounting hole 35 by the No. 2 spring 318, and the No. 2 straight rod 311 can be driven to be withdrawn from the No. 3 slide groove 313, so that the No. 1 clamping block 314 is withdrawn from the No. 1 clamping groove 39, so that the positioning rod 38 and the positioning hole 34 are released from the fixed connection, thereby facilitating the removal of the bearing body 2 from the flange 1, so that the flange 1 can be recycled. However, the No. 2 spring 318 drives the No. 1 slide plate 36 to move to the outside of the mounting hole 35, and it cannot be guaranteed that when the positioning rod 38 is fixed in the positioning hole 34, the No. 1 slide plate 36 is in the mounting hole 35. The stability of the positioning rod 38 is reduced, and the stability of the positioning rod 38 fixed in the positioning hole 34 is reduced, thereby reducing the stability of the installation component 3 on the bearing body 2. Therefore, a fixing component 4 is provided. When the positioning rod 38 is fixed in the positioning hole 34, the No. 1 slide 36 moves to one side of the mounting hole 35, and then the No. 3 spring 45 drives the No. 3 slide block 43 to move to the outside of the No. 4 slide groove 42, thereby driving the No. 2 clamping block 44 to move in the direction of the No. 2 clamping groove 41, so that the No. 2 clamping block 44 is inserted into the No. 2 clamping groove 41, thereby fixing the No. 2 clamping block 44 with the No. 1 slide 36, and then fixing the No. 1 slide 36 inside the mounting hole 35, so that the No. 1 slide 36 can stay stably in the mounting hole 35, thereby improving the stability of the positioning rod 38 in the positioning hole 34, and then improving the stability of the installation component 3 on the bearing body 2.

[0048] In the above embodiment, the No. 2 clamping block 44 is inserted into the No. 2 clamping slot 41. The No. 1 slide plate 36 is fixed inside the mounting hole 35, so that the No. 1 slide plate 36 can stay stably in the mounting hole 35, thereby improving the stability of the positioning rod 38 in the positioning hole 34. However, when the bearing body 2 is disassembled, the No. 1 slide plate 36 needs to be moved, but the No. 2 clamping block 44 cannot be stably taken out from the No. 2 clamping slot 41, thereby releasing the fixation of the No. 1 slide plate 36, and reducing the use effect of the fixing component 4. Therefore, a control component 5 is provided. When it is necessary to release the fixation of the No. 1 slide plate 36, the rotating ring 514 is first manually driven to rotate, and the No. 2 internal gear 513 is driven to rotate in the No. 4 mounting slot 512 at the same time, thereby driving the eight external gears 511 to rotate in the No. 3 mounting slot 58 at the same time. At the same time, it drives the No. 1 internal gear 59 to rotate, and then drives the four No. 2 gears 57 to rotate in the No. 2 mounting groove 56 at the same time, and then through the No. 4 straight rod 55, the four No. 1 gears 54 can be driven to rotate in the No. 1 mounting groove 51 at the same time, and then through the meshing connection between the No. 1 gear 54 and the rack groove 53, the rack groove 53 is driven to move into the No. 1 mounting groove 51, and at the same time, the four No. 3 straight rods 52 are driven to move into the No. 1 mounting groove 51, thereby driving the No. 2 clamping block 44 to move into the No. 4 sliding groove 42, so that the No. 2 clamping block 44 is pulled out of the No. 2 clamping groove 41, and then the fixation of the No. 1 slide plate 36 is released, so that the No. 1 slide plate 36 can move, thereby improving the use effect of the fixing component 4.

[0049] like Figure 4 , Fig. 9 As shown, a connecting component 6 is arranged between the No. 1 inner ring 22 and the No. 2 inner ring 23, an annular groove 61 is provided on the outer surface of the No. 1 inner ring 22 near the side of the No. 2 inner ring 23, an annular plate 62 is fixedly connected to the position corresponding to the annular groove 61 on the outer surface of the No. 2 inner ring 23, and the annular plate 62 is engaged with the annular groove 61, four evenly distributed No. 5 slide grooves 64 are provided on the inner circular surface of the No. 2 inner ring 23 and the inner circular surface of the annular groove 61, and No. 3 clamping grooves 63 are provided on one side of the outer surface of the four No. 1 slide bars 32 and the inner circular surface of the annular plate 62 corresponding to the No. 5 slide grooves 64, a No. 4 slider 65 is slidably connected inside the No. 5 slide grooves 64, a No. 3 clamping block 66 is fixedly connected to the outer surface of the No. 4 slider 65 near the No. 3 clamping groove 63, and a No. 4 spring 67 is provided on the outer surface of the No. 4 slider 65 away from the No. 3 clamping block 66.

[0050] In the above embodiment, because the inner ring in the bearing body 2 is composed of the No. 1 inner ring 22 and the No. 2 inner ring 23, and the No. 1 inner ring 22 is fixed in the positioning hole 34 by the positioning rod 38, the No. 1 inner ring 22 is fixed on the flange 1, thereby fixing the bearing body 2 on the flange 1, but the No. 2 inner ring 23 and the No. 1 inner ring 22 are very easy to separate, and it is easy for the No. 2 inner ring 23 to be separated from the bearing body 2, so a connecting assembly 6 is provided, and when the No. 1 inner ring 22 and the No. 2 inner ring 23 are fitted, the annular The plate 62 is inserted into the annular groove 61, and then the No. 4 slide block 65 is driven to move to the outside of the No. 5 slide groove 64 through the No. 4 spring 67, and at the same time the No. 3 clamping block 66 is driven to move to the outside of the No. 5 slide groove 64, so that the No. 3 clamping block 66 is inserted into the No. 3 clamping groove 63, thereby fixing the annular plate 62 in the annular groove 61, and at the same time fixing the No. 1 slide bar 32 in the No. 2 inner ring 23, thereby fixing the No. 2 inner ring 23 and the No. 1 inner ring 22 together, which can effectively prevent the No. 2 inner ring 23 from detaching from the bearing body 2.

[0051] like Figure 4 , Fig. 9 As shown, a clamping assembly 7 is provided on the side of the outer surface of the No. 2 inner ring 23 away from the No. 1 inner ring 22, and the clamping assembly 7 includes a clamping ring 71 provided on the side of the outer surface of the No. 2 inner ring 23 away from the No. 1 inner ring 22, and the clamping ring 71 is slidably connected to the outer cylindrical surface of one side of the flange 1, and the inner cylindrical surface of the clamping ring 71 is fixedly connected to four evenly distributed No. 3 slide bars 72, and the four No. 3 slide bars 72 are respectively slidably connected to the inside of the four No. 1 slide grooves 31, and the outer surfaces of the four No. 3 slide bars 72 away from the clamping ring 71 are all provided with No. 5 mounting grooves 73, and the No. 5 mounting grooves 73 all extend into the clamping ring 71, and the inner walls of the four No. 1 slide grooves 31 are connected to the A No. 4 clamping groove 74 is provided at a position corresponding to the No. 5 mounting groove 73, and a No. 5 slider 75 is slidably connected inside the No. 5 mounting groove 73, and a No. 4 clamping block 76 is fixedly connected to the outer surface of the No. 5 slider 75 near the No. 4 clamping groove 74, and a threaded hole 77 is provided on the outer surface of the No. 5 slider 75 away from the No. 4 clamping block 76, and a threaded rod 78 is threadedly connected inside the threaded hole 77, and a No. 5 straight rod 79 is fixedly connected to the end of the threaded rod 78 away from the No. 5 slider 75, and one end of the No. 5 straight rod 79 passes through the outer circumferential surface of the tightening ring 71 and is fixedly connected to a rotating block 710, and a cross-shaped groove is provided on one side of the outer surface of the rotating block 710.

[0052] like Figure 4 , Fig. 9As shown, four evenly distributed No. 1 fixing holes 711 are opened on the side of the outer surface of the No. 2 inner ring 23 close to the clamping ring 71, and the four No. 1 fixing holes 711 respectively penetrate the four No. 5 slide grooves 64 located in the No. 2 inner ring 23; No. 2 fixing holes 712 are opened on the one side of the outer surface of the No. 1 inner ring 22 at positions corresponding to the No. 1 fixing holes 711, and the four No. 2 fixing holes 712 respectively penetrate the four No. 5 slide grooves 64 located in the No. 1 inner ring 22; through holes 713 are opened on one side of the outer surface of the No. 4 sliding block 65, and the through holes 713 are connected with the No. 1 fixing hole 711 and the No. 2 fixing hole 712; fixed straight rods 714 are fixedly connected at the positions corresponding to the four No. 1 fixing holes 711 on one side of the outer surface of the clamping ring 71, and the fixed straight rods 714 are inserted into the No. 1 fixing hole 711 and the No. 2 fixing hole 712, and the fixed straight rods 714 penetrate the through holes 713.

[0053] In the above embodiment, the bearing body 2 is fixed to the flange 1 by fixing the positioning rod 38 in the positioning hole 34. However, the hub bearing needs to be rotated at high speed frequently when in use, and the positioning rod 38 is fixed in the positioning hole 34 to fix the No. 1 inner ring 22 to the flange 1. Only one side of the bearing body 2 can be fixed to the flange 1, which reduces the fixing effect of the bearing body 2 and the flange 1, thereby reducing the use effect of the mounting assembly 3. Therefore, a clamping assembly 7 is provided. When the bearing body 2 is fixedly mounted on the flange 1, the four No. 3 slide bars 72 are respectively connected to the four No. 1 slide grooves 31 for sliding connection, and the clamping ring 71 is sleeved on the other side of the bearing body 2 on the flange 1, so that the clamping ring 71 is tightly attached to one side of the No. 2 inner ring 23, and then the clamping ring 71 is fixed to the flange 1 through the ten No. 3 slide bars 72 opened on the outer surface of the rotating block 710. The U-shaped groove allows a cross-shaped or straight screwdriver to rotate the rotating block 710, and then the threaded rod 78 is driven to rotate through the No. 5 straight rod 79, and then the threaded connection between the threaded rod 78 and the threaded hole 77 can drive the No. 5 slider 75 to move downward inside the No. 5 mounting groove 73, thereby driving the No. 4 clamping block 76 to move downward, so that the No. 4 clamping block 76 is inserted into the No. 4 clamping groove 74, and then repeat the above steps to insert the four No. 4 clamping blocks 76 into the four No. 4 clamping grooves 74, thereby fixing the clamping ring 71 to the flange 1, and at the same time, the No. 1 inner ring 22 and the No. 2 inner ring 23 are clamped together through the clamping ring 71 and the flange 1, so that both sides of the bearing body 2 are fixed on the flange 1, thereby improving the fixing effect of the bearing body 2 and the flange 1, and thereby improving the use effect of the mounting assembly 3.

[0054] Usage: First, install the No. 1 inner ring 22 on the flange 1, then fix the No. 1 inner ring 22 on the flange 1 through the installation component 3, and start the fixing component 4 to fix the position of the No. 1 slide 36, then place a group of rolling bodies 24 on the outer circumference of the No. 1 inner ring 22, and then place the outer ring 21 on a group of rolling bodies 24, and then place another group of rolling bodies 24 inside the outer ring 21, so that the two groups of rolling bodies 24 are located inside the outer ring 21, and finally install the No. 2 inner ring 23 on the flange 1, and connect the No. 2 inner ring 23 with the No. 1 slide 36 through the connecting component 6. The inner ring 22 is fixedly connected to form the bearing body 2, and the bearing body 2 is fixed on the flange 1 at the same time, and then the clamping assembly 7 is started to clamp the bearing body 2 and fix it on the flange 1. When the bearing body 2 is damaged and needs to be removed, first remove the clamping ring 71 from the flange 1 through the clamping assembly 7, and then start the control assembly 5 to drive the No. 2 clamping block 44 to be pulled out from the No. 2 clamping groove 41, thereby releasing the fixation of the No. 1 slide plate 36, and then start the installation assembly 3 to release the fixation of the bearing body 2, and remove the bearing body 2 from the flange 1.
