Product Description Points You Might be Concerned1. About priceElectric linear actuators and simulation platforms are customized products, so the prices may vary from different specifications. The price on the page is just for reference, the actual final price is decided by the model selection.2. Multiple SolutionsWe can not only provide complete integrated simulators, but also semi-made simulators, like the 3dof/4dof/5dof/6dof/7dof simulation platforms or just certain electric linear actuators, then users can set up the simulator by themself to save total cost.3. Can I get help if I set up a simulator by myself?Absolutely Yes, we will provide technical support, advice, as well as motion platform manuals, servo motor manuals and driver manuals, etc.Product DescriptionThe work principle of heavy duty electric cylinderHeavy-duty electric cylinders are devices that convert the rotational motion of a motor into linear motion. They have the characteristics of high load, high precision and high rigidity and are widely used in industrial automation, heavy machinery, aerospace and other fields. 1. Core components-Motor (servo motor, stepper motor or AC motor): provides rotational power.-Transmission mechanism (ball screw, planetary roller screw or trapezoidal screw): converts rotational motion into linear motion.-Cylinder body: support and guide structure, bearing external load.-Position feedback device (such as encoder, grating ruler): realizes closed-loop control and ensures accuracy.-Brake (optional): prevents the load from sliding down when the power is off.2. Workflow-Motor driveThe motor rotates after receiving a control signal (such as a PLC or motion controller command) and outputs torque.-Motion conversionThe torque is transmitted to the screw (such as a ball screw) through a coupling or a synchronous belt. The rotation of the screw forces the nut to move axially, pushing the piston rod to extend or retract.-Load pushThe piston rod is directly connected to the external load, pushing and pulling it linearly. The screw of a heavy-duty electric cylinder usually uses a planetary roller screw, which can withstand higher loads (up to tens of tons) and impact.-Closed-loop controlThe position feedback device monitors the piston rod position in real time, and the signal is fed back to the controller, which dynamically adjusts the motor movement to ensure positioning accuracy (up to ±0.01mm).3. Heavy-duty design features-High rigidity structure: high-quality alloy cylinder and reinforced bearings are used to resist lateral forces.-High thrust design: torque is amplified through multi-stage screws, hydraulic force amplification (hybrid type) or gearboxes.-Heat dissipation and sealing: built-in heat sink or forced cooling, dustproof seals to adapt to harsh environments.-Safety mechanism: overload protection, mechanical limit and emergency brake.Technical Parameters Linear Actuator ModelDGRHT-180Ball ScrewScrew lead(mm)20Diameter(mm)80Rated dynamic load(kgf)12911Max.motor power/55000W servo motor22000W servo motorRated Torque: 290NmRated Torque: 140NmRated speed: 1800rpmRated speed: 1500rpmSpeed reduction/11.53Max.rated speedmm/s600400166Max.rated thrustKN77.4116.1112.1Max.rated torqueN.m290435420Stroke rangemm10-3000Axial backlashmmGround ball screw0.05Rolled ball screw0.12(default rolled)300mm lead tolerancemmGround ball screw0.023Rolled ball screw0.05(default rolled)Repeatable position accuracymmGround ball screw±0.01Rolled ball screw±0.02(defautl rolled)Limit Swith/NPN, PNPInline type/√×√Parallel type/√√√Explanation of Model Name:Model DGRHT-180:Product Features1.
