The invention discloses a protection structure for bearing on an axle and a motorcycle. The protection structure comprises a gear box and wheels, the gear box outputs the wheel shaft, the wheel shaft is sleeved with the bearing, and the wheels are in transmission connection with the wheel shaft; the gear box is provided with a first protection ring, the first protection ring extends towards one side of the wheel, and the first protection ring surrounds the periphery of the bearing; the wheels are provided with a second protection ring, the second protection ring extends towards one side of the gearbox and surrounds the periphery of the bearing, and a first protection gap is formed between the second protection ring and the first protection ring. One end of the axle extends out of the gear box, the wheels are in transmission connection with the axle, the axle is sleeved with the bearing, and the first protection gap is formed by the first protection ring on the gear box and the second protection ring on the wheels so that silt and the like brought up in the running process are prevented, the difficulty that the silt enters the bearing is increased, and thus the problem of noise caused by abrasion of the bearing is solved, and the service life of the bearing is prolonged.

    本发明公开了一种用于轮轴上轴承的防护结构及摩托车,包括齿轮箱和车轮,齿轮箱输出有轮轴,轮轴上套设有轴承,车轮与轮轴传动连接;齿轮箱设有第一防护环,第一防护环朝车轮的一侧延伸,第一防护环环绕在轴承的外周;车轮设有第二防护环,第二防护环朝齿轮箱的一侧延伸,第二防护环环绕在轴承的外周,第二防护环和第一防护环之间形成第一防护间隙。轮轴的一端伸出至齿轮箱外,车轮与轮轴传动连接,轮轴上套设有轴承,由于齿轮箱上的第一防护环和车轮上的第二防护环形成有第一防护间隙,从而对行驶过程中带起的泥沙等起到了阻止作用,增加了泥沙进入轴承的难度,从而解决了因轴承磨损导致的噪音问题,并延长了轴承的使用寿命。
