Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel hub bearing technology, specifically a dustproof device for wheel hub bearings. Background Technology
[0002] Wheel hub bearings are components used in automobile axles to bear weight and provide precise guidance for the rotation of the wheel hub. They bear both axial and radial loads and are an important part of the vehicle's load-bearing and rotation. Traditional automobile wheel bearings consist of two sets of tapered roller bearings or ball bearings. The installation, lubrication, sealing, and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes assembly difficult, costly, and unreliable in automobile manufacturing plants. Moreover, when the vehicle is maintained at a repair shop, the bearings need to be cleaned, lubricated, and adjusted. Therefore, a dustproof device for wheel hub bearings is used when in use.
[0003] Some existing dustproof devices do not fit precisely with the wheel hub bearings after installation, leaving large gaps that allow dust, mud, and other impurities to enter. This accelerates the wear of internal bearing parts, reduces bearing life, and increases noise and vibration during vehicle operation. Utility Model Content
[0004] The purpose of this utility model is to provide a dustproof device for wheel hub bearings, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof device for wheel hub bearings, including reinforcing components.
[0006] A mounting plate that is fixedly installed at the bottom of the reinforcement component;
[0007] And a dustproof component disposed on the side of the reinforcement;
[0008] The dustproof component includes a dustproof mechanism disposed at the top of the reinforcement component;
[0009] An installation mechanism is provided on the side of the reinforcement component.
[0010] Preferably, a bearing body is fixedly mounted on the top of the reinforcement, and an mounting component is fixedly mounted on the top of the bearing body.
[0011] Preferably, the dustproof mechanism includes a dustproof cover one, the inner wall of the dustproof cover one being in contact with the side wall of the bearing body, a dustproof cover two being in contact with the side wall of the dustproof cover one, a bolt being rotatably mounted on the inner wall of the dustproof cover one, one end of the bolt being movable through the inner wall of the dustproof cover one and extending to the inner wall of the dustproof cover two where a circular hole is opened, and a nut being installed on the side wall of the bolt.
[0012] Preferably, the inner wall of the nut is threaded to the side wall of the bolt, and the side wall of the nut is in contact with the side wall of the dust cover.
[0013] Preferably, the first dust cover and the second dust cover are of the same shape and size, and the inner wall of the second dust cover is in contact with the side wall of the bearing body.
[0014] Preferably, the mounting mechanism includes a screw, the side wall of which is rotatably connected to the inner wall of the reinforcing member, the bottom of which movably penetrates the inner wall of the mounting plate, and a fixing block is fixedly mounted on the top of the screw.
[0015] Preferably, there are four screws, and the four screws are all of the same shape and size.
[0016] This utility model provides a dustproof device for wheel hub bearings. It has the following beneficial effects:
[0017] (1) In this utility model, the operator installs dust cover one and dust cover two on the side wall of the bearing body. Then, the positions of dust cover one and dust cover two can be stabilized by bolts and nuts. Dust cover one and dust cover two can be used to connect with the mounting part of the wheel hub bearing. The closed end is used to block external impurities and can effectively block splashing mud and dust. This solves the problem that some existing dust protection devices have low matching accuracy with the wheel hub bearing after installation, and there are large gaps, which provide a channel for the intrusion of dust, mud and other impurities, which will aggravate the wear of the internal parts of the bearing, reduce the service life of the bearing, and increase the noise and vibration during vehicle operation.
[0018] (2) With this utility model, the position of the bearing body can be installed by the operator. After the position of the bearing body is determined, the position of the fixing block can be rotated directly. The fixing block drives the position of the screw to rotate, and the bearing body can be installed quickly. Attached Figure Description
