A telescopic linear actuator includes a rotational drive mechanism specially adapted and assembled within a tubular housing to reduce noise and vibration of the actuator during its operation. The rotational drive mechanism includes an electric motor adapted for low current operation, a gearbox containing a planetary gear axially connected to the motor with a stepped-up gear ratio, and a drive screw member operatively connected to the gearbox to extend longitudinally through the tubular housing. The drive screw is provided with a specially configured threaded surface formed along the screw member having a reduced thread count and associated increased thread pitch to operatively engage and drive a movable piston member through the tubular housing.
A telescopic linear actuator for movement of an article coupled thereto in opposite longitudinal directions with reduced noise levels, comprising:
A telescopic linear actuator for linear movement of an article coupled thereto in opposite longitudinal directions with reduced noise levels, comprising:
A method of operating a telescopic linear actuator including a tubular housing and a rotational drive assembly contained within the tubular housing, wherein the rotation drive assembly includes a reversible electric motor with a motor output, a planetary gearbox connected to the motor output, and a drive screw engaged with the planetary gearbox, the method comprising:
