BERG SPRING STACKS

The actuation force for the clamping means

Application : Spring stacks are used in machining spindles for mechanically generating the acutation force for the clamping means.

Design features: BERG-Spanntechnik uses special disc springs developed for this spring stacks application and having a very high energy density. This permits compact spring packages and short spindle lengths. The single spring arrangement used makes it possible to achieve optimum power constancy without the lubrication-dependent jacket friction of multiple arrangements. The special springs are manufactured with substantially limited play to the draw-bar which leads to a very stable and well-balanced quality of the clamping system. The familiar problems associated with screw plate springs with torques during the spring stroke do not occur with these spring packages. BERG-Spanntechnik spring packages are designed to be fatigue resistant.

Ordering example : Spring stacks are offered as spindle equipment in a complete unit including draw-bar, connector and actuation in combination with an attendant gripper.

Comments : In addition to the spring stacks listed in the table for the gripper standard sizes, BERG-Spanntechnik supplies the attendant spring stacks for any special gripper and application.
