The invention relates to the technical field of machine-room-free speed governors, and discloses a throwing piece type machine-room-free speed governor with an eccentric wheel meshing with a brake disc. The throwing piece type machine-room-free speed governor comprises a speed limiting mechanism, a steel wire rope is arranged on one side of the speed limiting mechanism, an elevator is fixedly connected to the bottom of the steel wire rope, guide rails are arranged on the two sides of the elevator, a buffer is arranged at the bottom of the elevator, a counterweight block is arranged at the end, far away from the elevator, of the steel wire rope, a mounting seat is arranged at the bottom of the speed limiting mechanism, and the speed limiting mechanism comprises the eccentric wheel. According to the throwing piece type machine-room-free speed governor with the eccentric wheel meshing with the brake disc, when the speed of the elevator is too high, the speed of the elevator can be decreased firstly through gear meshing brake between the eccentric wheel and a throwing piece structure. Meanwhile, rotating rods swing outwards under the action of centrifugal force, locking of connecting rods is relieved, the first gear is quickly stopped by quickly clamping the connecting rods with limiting grooves, the first gear is pressed to limit the movement of the elevator on the guide rails, stopping is conducted, rope clamping is firm, and safety is high.

    本发明涉及无机房限速器技术领域,且公开了一种偏心轮与制动盘啮合的甩片式无机房限速器,包括限速机构,限速机构一侧设置有钢丝绳,钢丝绳底部固定连接有电梯,电梯两侧设置有导轨,电梯底部设置有缓冲器,钢丝绳远离电梯的一端固定安装有对重块,限速机构底部设置有安装座,限速机构包括偏心轮。该一种偏心轮与制动盘啮合的甩片式无机房限速器,电梯速度过快通过偏心轮与甩片结构之间的齿轮啮合制动可以使电梯速度先一步下降,同时通过转动杆在离心力作用下向外侧甩动,解除连杆的锁定,使连杆通过迅速与限位槽夹紧使第一齿轮迅速制停,通过对第一齿轮进行压紧限制电梯在导轨移动进行制停,夹绳牢固、安全性高。
