Regarding load (load)
As Su Shi said, "Read widely and select carefully; accumulate knowledge and express it concisely." Today's lesson from Little Tang is about load/load characteristics of electric linear actuators. Pay attention here, this is important:
1. The difference between dynamic load and static load
2. How to set up electronic load sensing
3. The difference between tensile load and compressive load in electric linear actuators.
4. What is lateral load and its effect on electric linear actuators?
Static load is the load on the electric linear actuator when it is stationary and without power. Dynamic load is the load on the electric linear actuator when it is in motion and energized.
How to set up electronic load sensing
Typically, the last step in the Thomson factory production line is to set an electronic load for each actuator. This ensures that each actuator meets its rated load specifications, which eliminates the effects of manufacturing tolerances, lead screw and gear wear.
The difference between tensile load and compressive load in electric linear actuators
The tensile load is a tension electric actuator, while the compressive load is a compression electric actuator.
What is lateral load and its effect on electric linear actuators?
Lateral loads cause radial forces to be applied to the push rod, not along the direction of its extension. For example, they may be caused by unsupported loads, incomplete installation, or other external forces acting on the push rod.
Lateral loads can cause the internal components of the push rod to deviate from their normal orientation, leading to friction between the telescopic tube and the end cap, preventing the ball nut from running smoothly along the lead screw, and even damaging the gears. This can potentially cause irreparable damage to the push rod.
The force applied to the electric linear actuator should be in the same direction as the movement of the telescopic tube, as described in the "Installation" section of the electric linear actuator installation manual and the THOMSON catalog.
Thomson's electric cylinders are specifically designed for some lateral loads, and the telescopic tube has additional bearing support.
