Abstract
A linear actuator with an adjustable stroke length. The linear actuator includes a main rod that moves along a linear stroke length. At least one end of the stroke length is defined by a limit switch. The linear actuator includes an adjustment mechanism which is configured to allow a user to change the stroke length of the device by moving the limit switch without having to open the linear actuator.
Claims18
An electric linear actuator with an adjustable stroke length, the linear actuator comprising:
- an electric motor;
- a lead screw fitted with a nut;
- a gear box to transfer force from the motor to rotate the lead screw;
- a main rod configured to extend and to retract based on a rotation of the lead screw;
- an extension limit switch configured to stop an extending rotation of the lead screw when the main rod is at a maximum extension;
- a retraction limit switch configured to stop a retracting rotation of the lead screw when the main rod is at a minimum extension;
- and
- an adjustment mechanism connected to at least one of the extension limit switch and the retraction limit switch to adjust a position of the at least one of the extension limit switch and the retract limit switch, changing at least one of the maximum extension and the minimum extension of the main rod.
5 more elements
A linear actuator with an adjustable stroke length, the linear actuator comprising:
- a body;
- a main rod configured to extend and to retract from the body;
- at least one limit switch configured to stop the main rod from extending or retracting past a position of the at least one limit switch thereby defining an end point of a stroke of the main rod;
- and
- an adjustment mechanism operably connected to the at least one limit switch, the adjustment mechanism configured to adjust a position of the at least one limit switch, thereby altering the end point of the stroke of the main rod.
