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.
Claims21
An actuator, comprising:
- a housing having a first end, wherein an aperture is positioned at the first end of the housing;
- an actuator rod extending through the aperture along an axis of the actuator, the actuator rod operable to be driven with a bidirectional stroke, wherein the bidirectional stroke comprises an operational range and an end-of-stroke range;
- and
- a snubber assembly mounted at the first end of the housing, wherein 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,
- wherein the snubber assembly is configured such that the one or more energy absorbing devices provide bidirectional damping to the end-of-stroke range motion of the actuator rod,
- wherein the snubber assembly includes a frame that is configured to receive the one or more energy absorbing devices, wherein the frame includes a first frame part and a second frame part, and the one or more energy absorbing devices are positioned between the first frame part and the second frame part,
- wherein the first frame part is moveable relative to the second frame part along the axis of the actuator, and
- the first frame part and the second frame part are moveable relative to the housing along the axis of the actuator.

An actuator, comprising:
- a housing having a first end and an aperture positioned at the first end of the housing;
- an actuator rod extending through the aperture along an axis of the actuator, the actuator rod operable to be driven with a bidirectional stroke, wherein the actuator rod has an operational range and at least one end-of-stroke extension range;
- and
- a snubber assembly mounted at the first end of the housing, wherein 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,
- wherein 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,
- wherein 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,
- wherein the snubber assembly includes a frame that is configured to receive the one or more energy absorbing devices, and the frame includes a first frame part and a second frame part, and the one or more energy absorbing devices are positioned between the first frame part and the second frame part,
- wherein the first frame part is moveable relative to the second frame part along the axis of the actuator, and
- the first frame part and the second frame part are moveable relative to the housing along the axis of the actuator.
