摘要
为分析阀门传动元件在自重作用下带动电装进行旋转的现象,对电装两种自锁方式:电磁自锁和机械自锁进行对比分析,电磁自锁需要通电运行,机械自锁不需要通电运行。通过分析得出电磁自锁对于阀门齿轮较机械自锁损伤小,在通电情况下电磁自锁能力优于机械自锁,电磁自锁在不通电的情况适用于大口径阀门且阀门传动部件重力小于电装本身减速器的摩擦力,在热态后可满足轻量冲击、振动、倾斜摇摆工况,在通电的情况下适合任一工况;在不通电情况下,电磁自锁失效,性能劣于机械自锁,机械自锁适用于小口径阀门且自锁力矩要小于齿轮许用应力引起的变形,同时要注意减速器齿轮的配比。
In order to analyze the phenomenon that the valve transmission element drives the electric assembly to rotate under the action of self-weight,the electric assembly two self-locking methods:electromagnetic self-locking and mechanical self-locking are compared and analyzed.The electromagnetic self-locking needs power operation,and the mechanical self-locking does not need power operation.Through analysis,it is concluded that electromagnetic self-locking has less damage to valve gear than mechanical self-locking,and the electromagnetic self-locking ability is better than mechanical self-locking under energized condition.Electromagnetic self-locking is suitable for large-caliber valves without energized condition,and the gravity of the valve transmission component is less than the friction of Denso's reducer,which can meet the conditions of light impact,vibration,tilt and sway after hot condition.Suitable for any working condition in the case of power;In the case of no power,electromagnetic self-locking failure,the performance is inferior to mechanical self-locking,mechanical self-locking is suitable for small-caliber valves and self-locking torque is less than the allowable stress caused by the deformation of the gear,while paying attention to the ratio of the reducer gear.
