The invention relates to an additional brake and an escalator or a moving walk. The auxiliary brake comprises a driving sprocket and a friction plate, wherein a containing cavity is formed in the driving sprocket, the outer circumference of the driving sprocket is used for being sleeved with a driving chain, a first oil blocking groove is formed in the outer circumferential wall of the driving sprocket, and the first oil blocking groove is located between the driving chain and the containing concave cavity; and the friction plate is arranged in the containing cavity. Due to the fact that the first oil blocking groove is formed in the outer circumferential wall of the driving sprocket, in the running process, lubricating oil coated on the driving sprocket and the driving chain is blocked by the first oil blocking groove, the lubricating oil can only flow into an oil receiving disc along the first oil blocking groove, and cannot flow into the containing cavity and contaminate the surface of the friction plate, so that the friction coefficient of the friction plate cannot be reduced, the additional brake is ensured to have excellent braking performance, and the escalator or the moving walk can be ensured to continuously, normally and safely run.

    本发明涉及一种附加制动器及自动扶梯或自动人行道,包括:驱动链轮,所述驱动链轮的内部形成有容置凹腔,所述驱动链轮的外圆周用于套装驱动链条,所述驱动链轮的外周壁设有第一阻油沟槽,所述第一阻油沟槽位于所述驱动链条与所述容置凹腔之间;以及摩擦片,所述摩擦片设置于所述容置凹腔内。由于驱动链轮的外周壁设置有第一阻油沟槽,在运行过程中,涂覆于驱动链轮与驱动链条上的润滑油由于受到第一阻油沟槽的阻挡作用,润滑油只能够沿着第一阻油沟槽顺流至接油盘中,而无法流入容置凹腔内并沾染到摩擦片的表面,因而可以保障摩擦片的摩擦系数不会降低,保证附加制动器具有优良的制动性能,确保自动扶梯或自动人行道能够持续正常安全运行。
