高速旋转限速稳速器

High-speed Rotating Speed-limit & Speed-stabilizing Actuator

研究设计一种循环式救生梯旋转限速器,它能自动降低救生梯转盘的转动速度,并提高转动速度的稳定性,从而控制循环式救生梯的升降速度;而且它还能自动适应负载的变化,在负载从100kg到1000kg的变化过程中速度没有明显的变化;并论述了结构原理。对循环式救生梯进行了装车试验,试验结果表明,所研制的样机性能指标满足规定的要求。

this article tells a rotating speed-limit actuator which is used on a recycling emergency ladder.This actuator can reduce the rotating speed of the turntable on the emergency ladder.Thus it can increase the rotating stability so as to control the hoisting speed.At the same time,this actuator can adjust to the load change automatically.There is no marked change in the speed if the load change from 100kg to 1000kg.This article also introduces the structure and principle.We have tested the actuator by assembly the emergency ladder to the truck.The result proves that our actuator can satisfy all the requirement.
