Title:
主ロッドと副ロッドを有するアクチュエータ
Document Type and Number:
Japanese Patent JP4856211
Kind Code:
B2
Abstract:
The actuator has brake units (106, 110) e.g. magnetic braking units, to brake sliding of an auxiliary rod (20) in a main rod (2) in an extension direction. The auxiliary rod comprises a thread (101) on an outer surface. The main rod has an end carrying a rotary bearing (102), which centers the auxiliary rod in the main rod and co-operates with the thread via a reversible helical connection such that extension of the auxiliary rod causes the bearing to rotate. The brake units brake the rotation of the bearing during extension of the auxiliary rod.
