Claim 0:
1. A toothed safe braking apparatus for use in a robotic joint, wherein a robot comprises a main support (5), and the robotic joint comprises a shaft (C), wherein the toothed safe braking apparatus for use in a robotic joint further comprises:
an electromagnetic telescoping apparatus (6), mounted on the main support (5), and provided with a working bit (17) capable of moving between a locked position and an unlocked position along the direction of an axis of the shaft (C) of the robotic joint; and
a friction engagement component (10), mounted to the shaft (C) of the robotic joint, the friction engagement component (10) comprising:
a disc-shaped brake lock ring gear (1), provided with teeth (11) arranged on the outer circumference thereof and a first center fitting hole (12);
a disc-shaped pretension ring (2), provided with a second center fitting hole (13); and
a disc-shaped brake hub (4), provided with a first end surface (14), a second end surface (15), and an outer circumferential surface (16);
wherein the brake lock ring gear (1) and the pretension ring (2) are arranged in parallel via the first center fitting hole (12) and the second center fitting hole (13) to be friction engaged on the outer circumferential surface (16) of the brake hub (4); and
wherein in the locked position, the working bit (17) of the electromagnetic telescoping apparatus (6) can be engaged with the teeth (11) on the brake lock ring gear (1) of the friction engagement component (10), and in the unlocked position, the working bit (17) of the electromagnetic telescoping apparatus (6) can be disengaged from the teeth on the brake lock ring gear (1) of the friction engagement component (10); and
wherein the outer circumferential surface (16) of the brake hub (4) has a first conical surface (8) inclined upward from the first end surface (14) and a second conical surface (9) inclined upward from the second end surface (15).
