A retaining spring is provided on the inner ring of the bearing, and is located behind the mounting plate, and is used to fix the mounting plate, ensure the position of the mounting plate on the inner ring of the bearing, and prevent the rubber composite cover from moving toward the middle of the bearing.
[0008] In a possible implementation, the rubber composite cover is provided with three layers of rubber protrusion layers, and the three layers of rubber protrusion layers extend and adhere to the inner side wall of the dust cover. The rubber composite cover is provided with three layers of rubber protrusion layers, and the three layers of rubber protrusion layers extend and adhere to the inner side wall of the dust cover, providing a better sealing effect.
[0009] In a possible implementation, the mounting plate is formed by a bottom plate mounted on the inner ring of the bearing, which is bent upward, then bent backward, and then bent upward once more, and the bottom of the rubber composite cover is mounted against the mounting plate. The mounting plate is formed by a bottom plate mounted on the inner ring of the bearing through multiple bendings. This structure helps to improve the stability and load-bearing capacity of the mounting plate. The bottom of the rubber composite cover is mounted against the mounting plate to ensure a tight fit between the sealing cover and the inner ring of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS
