Abstract

A toothed safe braking apparatus for use in robotic joint, comprising an electromagnetic telescoping apparatus () and a friction engagement component (). The friction engagement component () is mounted on a shaft (C) of the robotic joint and comprises a brake lock ring gear () provided with a first center fitting hole (), the brake lock ring gear () being provided with teeth () arranged on the outer circumferential surface thereof, a pretension ring () provided with a second center fitting hole (), and a brake hub () provided with a first end surface (), a second end surface (), and an outer circumferential surface (). On a locked position, a working bit () of the electromagnetic telescoping apparatus () can be engaged with the teeth () on the brake lock ring gear () of the friction engagement component (); and, on an unlocked position, the working bit () of the electromagnetic telescoping apparatus () can be disengaged from the teeth () on the brake lock ring gear () of the friction engagement component (). The brake lock ring gear () and the pretension ring () are arranged in parallel via the first fitting hole () and the second fitting hole () to be friction engaged on the outer circumferential surface () of the brake hub ().
