Description

Technical Field

[0001] The utility model belongs to the field of wheel hub bearings, and in particular relates to a wheel hub bearing which is easy to disassemble and assemble. Background Art

[0002] The wheel hub bearing is one of the key components of a car. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub, which requires it to be able to withstand not only axial loads but also radial loads.

[0003] When installing the wheel hub bearing, the inner and outer rings of the bearing are usually fitted together on one side, leaving a larger gap on the other side. The ball can then be installed there, and then the inner ring is struck hard to complete the installation of the bearing. During the striking process, the ball will be squeezed into the rolling groove inside the bearing, making it uneven, which greatly affects the performance of the bearing and the installation process is also relatively cumbersome.

[0006] The quick-release assembly comprises a screw ring rotating in the inner ring of the bearing, a pressure plate is movably mounted on the screw ring, at least two filling blocks are fixed to one end surface of the pressure plate, and the filling blocks are clamped on the inner ring of the bearing.

[0007] Optionally, the inner wall of the bearing outer ring and the outer peripheral side of the bearing inner ring are both provided with semi-arc grooves, and the two semi-arc grooves can form a complete annular groove, and a plurality of balls are arranged in the annular groove.

[0008] Optionally, at least two notches are opened on the outer peripheral side of the inner ring of the bearing, the notches are connected to the semi-arc grooves of the inner ring of the bearing, the filling blocks are located in the notches, and the notches are located on one side end surface of the inner ring of the bearing.

[0009] Optionally, the filling block just fills the position of the gap and is consistent with the missing part of the gap, and does not affect the rotation of the ball.

[0010] Optionally, the screw ring is threadedly connected to the bearing inner ring, and a hexagonal knob is fixed to an end surface of the screw ring away from the bearing inner ring, and the hexagonal knob is located on a side of the pressure plate away from the bearing inner ring.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the quick-release assembly, the removal and installation of the ball of the wheel hub bearing can be greatly facilitated, effectively avoiding the problem of bearing damage caused by extrusion during the installation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0018] As shown in Figures 1-3, a wheel hub bearing that is easy to disassemble and assemble includes a bearing outer ring 10, and two flanges 11 are provided on the outer peripheral side of the bearing outer ring 10. The characteristics are: two bearing inner rings 12 are detachably provided in the bearing outer ring 10, and a quick-release assembly is provided in the bearing inner ring 12. The quick-release assembly includes a screw ring 17 that rotates in the bearing inner ring 12, and a pressure plate 15 is movably installed on the screw ring 17. At least two filling blocks 14 are fixed to one end face of the pressure plate 15, which is clamped on the bearing inner ring 12 through the filling blocks 14. The screw ring 17 is threadedly connected to the bearing inner ring 12, and a hexagonal knob 16 is fixed to the end face of the screw ring 17 away from the bearing inner ring 12. The hexagonal knob 16 is located on the side of the pressure plate 15 away from the bearing inner ring 12.

[0019] The inner wall of the bearing outer ring 10 and the outer circumference of the bearing inner ring 12 are both provided with semi-arc grooves. The two semi-arc grooves can form a complete annular groove. A number of balls 13 are arranged in the annular groove. The outer circumference of the bearing inner ring 12 is provided with at least two notches. The notches are connected to the semi-arc grooves of the bearing inner ring 12. The filling block 14 is located in the notch. The notch is located on one end face of the bearing inner ring 12. The filling block 14 just fills the position of the notch and is consistent with the missing part of the notch, and does not affect the rotation of the ball 13.

[0020] When in use, the bearing inner ring 12 can be installed in the bearing outer ring 10 first, and then the balls 13 can be put in one by one through the notch on the bearing inner ring 12, and then the retainer can be clamped. At this time, the quick-release assembly can be installed. At this time, the filling block 14 can be placed in the notch of the bearing inner ring 12, and then the screw ring 17 can be screwed into the bearing inner ring 12. During the screwing process of the hexagonal knob 16, the screw ring 17 can rotate, while the pressure plate 15 and the filling block 14 cannot rotate. However, the rotation of the screw ring 17 can drive the pressure plate 15 and the filling block 14 to move into the bearing. The filling block 14 can be inserted into the inner ring 12 until the filling block 14 completely fills the gap in the inner ring 12 of the bearing. When disassembly is required, the retaining frame is disassembled first, and the hexagonal knob 16 can be rotated in the opposite direction to make the screw ring 17 drive the pressure plate 15 and the filling block 14 to be pulled out from the inner ring 12 of the bearing through the thread. Then the ball 13 can be poured out from the gap in the inner ring 12 of the bearing to complete the disassembly. The setting of the quick-release component can greatly facilitate the disassembly and installation of the ball 13 of the wheel hub bearing, and effectively avoid the problem of bearing damage caused by extrusion during the installation process.

[0021] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
