Title:
可変ばね定数の緩衝部材を備えた圧縮ばね型電磁ブレーキ装置
Document Type and Number:
Japanese Patent JP4418231
Kind Code:
B2
Abstract:
An electromagnetic compression spring brake comprising a backplate (1) including a solenoid (3) and helical springs (5) distributed equispaced in the backplate (1), a friction plate (4) on a hub of a shaft to be braked. The brake has a plurality of damping members (7, 8) distributed equispaced about the circumference and featuring a specific spring rate between the opposite faces of the backplate (1) and armature plate (2) for reducing the pull-in noise of the armature plate when impacting the face of the backplate (1). A further plurality of damping members (9 to 12) is distributed equispaced about the circumference of significantly lower spring rate for continual contact with the opposite face of the backplate (1) to reduce the drop-out noise of the armature plate (2) during braking. As an alternative, the face of the damping member is divided into a large face section for contacting the pulled-in armature plate (2) to reduce the pull-in noise, and into a smaller axially protruding face section for continual contact with the opposite face of the dropped out armature plate to reduce the drop-out noise.
