What Is a Linear Actuator?
A linear actuator is a linear actuator that consists of a ball screw or trapezoidal screw, which is the main component, in combination with a worm gear.
Linear actuators are jacks that can be operated in a straight line.
Linipower jacks are simple, compact, and economical.
Uses of Linear Actuators
The uses of Linear actuators are explained here.
A motor can drive the Linear power jack directly connected to the Linear actuator.
The trapezoidal screw type is mainly used for low-frequency and low-speed applications, taking advantage of the sliding contact of the trapezoidal screw. In contrast, the ball screw type is used for ultra-high-speed and high-frequency applications.
Linear actuators are also available with stainless steel screws resistant to rust in accordance with the operating environment. LD-type Linear actuators generate only a small amount of dust for clean rooms.
Principle of Linear Actuators
Next, the principle of Linear actuator is explained.
Linear actuators consist of a threaded part and a high-precision worm gear.
The screw part is a ball screw and a trapezoidal screw, each of which has different characteristics and applications.
The ball screw has high efficiency due to the shape of the screw part so that it can provide a large thrust force even with a small drive power, and it can also operate at high speeds.
They also have excellent durability and can be used for a long time with long service life.
The trapezoidal screw has a sliding contact and, due to the screw’s geometrical characteristics, has excellent alignment and self-locking properties, making it capable of supporting a load.
In addition to the general right-hand thread specification, left-hand thread jacks are available. The screw moves in the same direction of input rotation but in the opposite direction.
