Product Description
Replacing the hydraulic cylinders with 4000kgf Parallel Drive Electric Linear Actuators in power transmission. Electromechanical cylinders are available with acme screw drive. High linear speed even at high loads, improved efficiency by reducing energy consumption, better control of position, speed and force, great positioning accuracy and repeatability are only some of the reasons that make them the right alternative to hydraulic cylinders. Also available on different assembly configurations for a total interchangeability with the existing hydraulic units. Lubrication with synthetic grease, gearbox long life lubricated. Prepared for IEC standard AC motors. All stroke lengths can be adjusted downward with the position limit switch.
Working Principle
A trapezoidal lead screw and nut is driven by an electric motor, through a reduction gearbox. The lead screw converts rotary motion to linear movement. When the motor is activated, it rotates the screw, which moves the nut, the nut extends and retracts the piston rod, which is attached to the load.
Main Features
* Parallel drive configurations.
* Self-locking trapezoidal lead screw and nut (non-backdriving).
* Thrust force: 4000 kgf.
* Travel speed: 28 mm/s (slow speed), 42 mm/s (medium speed).
* Motor Power: 2.2 kW, 4 kW.
* There are no "standard" travel lengths, maximum 1200 mm.
* 3phase normal motor (380v 3ph AC) as standard. Brake motors are also available.
* Non-rotating extension rod with anti-rotation guide.
* Accessories: Brake motor, handwheel, external limit switches, bellows boots and clamps, trunnion mounting brackets, electrical control box, encoder, and stainless steel or chrome plated piston rod.
* Electric linear actuators and electric cylinders can be a real alternative to pneumatic and hydraulic cylinders.
Product Components
1. Motor
Motor: 3phase normal motor (380v 3ph AC) as standard. Brake motors are also available. it causes the actuator to travel forwards or backwards. All others 220v, 240v, 400v, 415v, 460v and 480v three phase motors for actuators can be supplied.
2. The First Gear (Steel)
3. Gearbox
4. The Second Gear (Steel)
5. The Third Gear (Steel)
6. Hand Wheel
Hand Wheel: is available for manual operation/adjustment of the actuator.
7. The Fourth Gear (Steel)
8. Trapezoidal Screw
Spindle: also known as the self-locking trapezoidal lead screw, rotating screw, or lifting screw, which is a long, straight rod that turns in a machine or tool. This linear actuator rotates, extending or retracting the nut/inner tube, which creates a linear motion.
9. Thrust Housing
10. Hammer Blow Pin
11. Safety Switches
Safety Switches: Interior limit switches control the fully extended and retracted inner tube position by electrically cutting current to the motor. These switches prevent the actuator from over extending or over retracting. It also protects the motor.
12. Thrust Limit Disc Springs
13. Drive Nut (Bronze)
Drive Nut: The lead screw nut is attached to the inner tube and travels along the spindle. The nut is the component that allows extension or retraction of the inner tube.
14. Anti-rotation Guide
15. Outer Tube
Outer Tube: Also known as the cover tube, this tube protects the outside of the linear actuator and houses all of the actuator's inner components. The housing is used for guiding the piston rod too.
16. Inner Tube (Piston Rod)
Inner Tube: Also known as the extension tube, drive tube, translating tube, thrust rod, push rod, or piston rod. It has internal anti-rotation guide.While retracted, the inner tube is where the spindle is located. This tube is attached to the threaded drive nut and extends and retracts when the nut moves along the rotating spindle. Custom stainless steel or chrome plated piston rod.
17. Front Clevis (Fork Head)
Front Clevis: Also known as the fork head. A clevis is a U-shaped metal piece with holes in each end through which a fastening device, a pin or bolt, is run.
18. Protective Bellows
Protective Bellows: Also known as the extension rod cover, to avoid the possible entry of particles or liquid through the piston rod.
19. Trunnion Pins and Trunnion Mounting Brackets
20. Anti-friction Bearings
