Abstract

The invention discloses a friction damping and driving limit actuator. The friction damping and driving limit actuator comprises a damping or driving device, a friction damping device, a limit lockingor unlocking device and a rotating assembly which is arranged in the damping or driving device, the friction damping device and the limit locking or unlocking device in a penetrating manner, whereinthe limit locking or unlocking device comprises a limit small ball and a limit mechanism; and the limit ball and the limit mechanism attract or repel each other to realize locking or unlocking. Compared with the prior art, the friction damping and driving limit actuator has the following beneficial effects that a series of actions of efficiently braking, locking, unlocking and driving are carriedout on executed part can be realized, an ideal braking effect can be simultaneously generated for high-speed braking and low-speed braking, electric energy converted in the electromagnetic damping process can be efficiently utilized for electromagnetic driving, and energy recycling is realized.

Description

technical field [0001] The invention relates to an electromagnetic and frictional damping buffer device, in particular to a novel electromagnetic frictional damping and drive limit actuator. Buffering and braking is the most common unsteady working condition in the mechanical field, and its buffering and braking performance is comparable to that of The braking device has a very important connection. Both electromagnetic damping and frictional damping can be used for the safety braking of the mechanism. A new type of actuator. Background technique [0002] According to the law of electromagnetic induction, when the magnetic rod enters the coil, an induced electric field will be generated, which always hinders the relative movement of the magnetic rod and forms a braking force on the magnetic rod. This phenomenon is called electromagnetic damping. The electromagnetic brake made according to the principle of electromagnetic damping has the advantages of simple structure, contr...
