The invention provides a waterproof method for a roller bearing of an escalator. A waterproof inner cover and a waterproof outer cover which are matched with each other are installed on the step shaft side of the rolling wheel bearing, an elastic lip opening on the waterproof inner cover abuts against the waterproof outer cover, and an annular clamping strip on the waterproof outer cover is matched with an annular clamping groove on the rolling wheel core to form a sealing structure, so that the sealing effect of the step shaft side of the roller bearing is effectively improved; the waterproof cover is arranged on the other side of the roller bearing, and the annular clamping strip on the waterproof cover is matched with the annular clamping groove on a roller core to form the sealing structure, therefore, external water cannot enter from any side of the roller bearing, the waterproof effect of the roller bearing is ensured, the roller bearing is prevented from being affected with damp and rusted to be damaged, the service life of the roller bearing is prolonged, and the maintenance cost of the escalator is reduced. Correspondingly, the invention further provides a waterproof assembly for the roller bearing of the escalator.

    本发明的自动扶梯滚轮轴承防水方法,在滚轮轴承的梯级轴侧安装相互配合的防水内盖和防水外盖,通过防水内盖上的弹性唇口和防水外盖相抵,以及防水外盖上的环形卡条和滚轮轮芯上的环形卡槽相配合形成密封结构,有效提高了滚轮轴承梯级轴侧的密封效果;通过在滚轮轴承的另一侧设置防水盖,且防水盖上的环形卡条与滚轮轮芯上的环形卡槽相配合形成密封结构;从而,使得外界的水无法从滚轮轴承的任一侧进入,保证了滚轮轴承的防水效果,避免了滚轮轴承受潮生锈出现损坏,延长了其使用寿命,并降低了自动扶梯的维护费用。对应的,本发明还提供了一种自动扶梯滚轮轴承防水组件。
