Abstract
An actuator including a housing, an actuator rod and a snubber assembly. The actuator has an axis, the housing has a first end and an aperture positioned at the first end of the housing, and the actuator rod extends through the aperture along the axis of the actuator. The snubber assembly is mounted at the first end of the housing, and includes one or more energy absorbing devices. The snubber assembly is positioned on the housing such that an axis of each of the one or more energy absorbing devices is offset relative to the axis of the actuator. The snubber assembly is configured such that the one or more energy absorbing devices provide bidirectional end-of-stroke damping.
Claims33
An actuator including a housing, an actuator rod and a snubber assembly, wherein:
- the actuator has an axis;
- the housing has a first end and an aperture positioned at the first end of the housing;
- the actuator rod extends through the aperture along the axis of the actuator;
- the snubber assembly is mounted at the first end of the housing;
- the snubber assembly includes one or more energy absorbing devices, and the snubber assembly is positioned on the housing such that an axis of each of the one or more energy absorbing devices is offset relative to the axis of the actuator;
- and
- wherein the snubber assembly is configured such that the one or more energy absorbing devices provide bidirectional end-of-stroke damping to motion of the actuator rod.

An actuator including a housing, an actuator rod and a snubber assembly, wherein:
- the actuator has an axis;
- the housing has a first end and an aperture positioned at the first end of the housing;
- the actuator rod extends through the aperture along the axis of the actuator, wherein the actuator rod has an extension range including at least one end-of-stroke extension range;
- the snubber assembly is mounted at the first end of the housing;
- the snubber assembly includes one or more energy absorbing devices, and the snubber assembly is positioned on the housing such that an axis of each of the one or more energy absorbing devices is offset relative to the axis of the actuator;
- the one or more energy absorbing devices are configured to prevent the actuator rod entering the at least one end-of-stroke extension range during controlled operation of the actuator;
- and
- the one or more energy absorbing devices are configured to deform, thereby allowing the actuator rod to enter the at least one end-of-stroke extension range, absorbing energy and damping motion of the actuator rod in the event of uncontrolled operation of the actuator.
