Product Details

1. Operational Principle

 

The electric cylinder is a linear motion that converts the rotating motion of the motor into the push rod through the rotating motion of the screw and the screw pair. By using the closed-loop control characteristic of servo motor, the precision control of thrust, speed and position can be realized conveniently, and the program can be realized by using modern motion control technology, numerical control technology and bus (network) technology. Because of its control and convenience, it can realize the precision motion control that cylinder and hydraulic cylinder drive can not realize.



 

 

2. Features:

 

TJE series electric cylinders adopt advanced modular design, with the feature of :
★ Compact structure and small dimension

★ High performance, low inertness, low noise ,high response

★ High reliability and long operating life

★ Application technology of both ball screws and roller screws

★ Convenient assembly and use, energy saving,simple maintenance
 

 

Material

★ Shell : forging aluminium alloy, smooth ,elegant appearance.

★ Extension Rod : high alloy steel, corrosion resistant.

Precision

★ Usually take both repeatability and motor precision into consideration. Should not take push rod of electric cylinder as guidance for straightness.The customer should design own guide mechanism.

★ Motor being connected parallel will decrease the precision compared with connected directly because it need to through synchronous belt gear.

Velocity★ Take the lifetime into special consideration under motion in high velocity(more than 200mm/s).The loading ability and precision will both decrease at the same time.
Stroke★ The stroke of model-selected should be 20-50mm larger than the effective stroke because we need to save space for slowing down and stopping after the push rod meeting the limited switch.Faster speed , larger space.
Thrust★ Gear drive will bring more thrust than synchronous belt drive under motor in parallel.
Operational Cycle Time★ Run frequently(more than 50%) or continuously by using ball screw.
Motor Choice

★ AC servo motor: high precision, high velocity ,great thrust and equilibrium step.

★ Stepping motor: high precision, slow velocity and not very great thrust (less than 600kg).

★ Normal DC motor can be implemented to regulate speed but not be positioned.

★ Normal asynchronous motor can't be regulated speed and positioned.

★ Special installation,preservation,dust prevention, dampproof

★ High&low temperature environment

★ Waterproof at sea, anti-explosion work

★ Linear displacement sensor

★ Pressure sensor

2)The sensor couldn’t be mounted on the same side of the motor when the motor is parallel mounted.

 

 

 

 

 

 

4. Electric Cylinder Selection Guidance

 


(1) The relationship between the motor output torque and the output force of the electric cylinder:


F=T×η×2π×R/L
★ F: electric cylinder output force, Unit: Kn

★ T: motor output torque, Unit: Nm

★ R: Reduction ratio

★ L: Screw lead,Unit: mm

★ η: efficiency (generally the total efficiency is 85%, but the actual efficiency will chage,it is based on the actual use conditions)


(2) The electric cylinder working life


The life of the electric cylinder generally refers to the internal use of the electric cylinder screw.It can be divided into two parts:

 

1). screw fatigue life, it can be got by calculating;

The following is a calculation method of the fatigue life .

 

L10=(Ca/Fm)3×L
★ L10: The life of the electric cylinder,unit: Km

★ Fm: Average load of electric cylinder,unit: Kn

★ Ca: Screw nut basic dynamic load, unit: Kn

(can be detected by screw samples)

★ L: Screw lead,unit: mm
 

2). another life, depending on the conditions of use ( such as temperature, dust, using the type of lubrication, and periodically add frequency, etc. ).This kind of life is often drawn from the experience.

 

 

(3) The calculation of the average load

Average load means:A cube average value be calculated according to the force,speed,time in different working areas during a working cycle.


The change in load of the electric cylinder

As shown below:
 



The average load of the electric cylinder is calculated as follows:
