2. 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:

3. Compared With Hydraulic Cylinder & Pneumatic Cylinders

4. Application areas:

★ Military equipment:radar, missile erector, armored vehicle swing platform, special equipment and other warships and aircraft hatch,opening, seat height adjustment, weapon tracking system,actuator,experimental lifting support, tank artillery high and low direction action adjustment, The push of rocket fuel, the opening of furnace door, etc.

★ Special equipment:industrial automation production line, assembly line, logistics transmission, lifting platform, offset control, valve control, coordinate manipulator, mechanical equipment CT Kama knife, food and medicine industry, CNC machine tools, industry packaging machine, Automotive electronic press, textile equipment winding machine indexing, die position control, clamping, drilling, positioning.

★ Experimental Equipment: Simulation platform, test bed, wave machine, testing equipment etc.

This type is especially suitable for :warp knitting machine, fast speed and quick response

5. Maintenance

★ Electric cylinder is refueled with lubricating grease GB7324-1994 general lithium base 3 lubricating grease when leaves factory.

★ After electric cylinder has run for 300 hours, refill the lubricating grease. Refueling frequency, per 2000hours one time as usual, it is determined on basis of the operating environment and day-to-day operational time.

★ Refueling method: open the filler hole on the shell of electric cylinder, turn the screw to find the filler hole on the screw nut and refuel lubricating grease.

★ Requirement for lubricating grease:GB7324-1994 general lithium base 3 lubricating grease.
