Electrical linear actuator is a kind of linear actuator equipment widely used in modern industry. With the continuous improvement of people's living standards, people's requirements for the safety of production and life have also been improved. When using this kind of electrical linear actuator, people often think like this. Is it safe to operate this kind of electrical linear actuator? Will there be any security problems? After all, there is only one life, so we must be careful in our daily operation. So, how about the safety performance of this electrical linear actuator?
I. Principle and Safety of Electrical linear actuator
1. The working principle of the electrical linear actuator is that the motor rotates through the turbine worm or gear to decelerate into linear motion, which drives the screw to work so that a device can complete reciprocating motion. In recent years, this kind of equipment has been widely used in the transmission of various simple and complex mechanical equipment. The main components of electrical linear actuator are motor, reducer gear, turbine worm, nut, screw, stroke switch, potentiometer, installation bracket, etc.
2. Electrical linear actuator screw is divided into two types: ordinary T-shaped teeth and ball screw. Ordinary T-teeth are suitable for occasions with low working frequency, and the electrical linear actuator works about 10 times per hour, which can be fully satisfied. T-tooth electrical linear actuator can realize complete self-locking function to ensure absolute safety of application. 3. Electrical linear actuator toothed screw completely self-locking, ball screw electrical linear actuator does not have self-locking function, but through the brake device on the motor, the motor brakes through the brake lock device. The self-locking performance of the electrical linear actuator at any position is better than that of the T-shaped teeth lead screw, and the self-locking coefficient in this state is less than 0.25. It not only meets the functional requirements, but also increases the safety of the final product.
2. Advantages of Electrical Linear Actuator
This kind of electrical linear actuator has large load, high precision, and can realize synchronous automation control. These characteristics make it widely used in mechanical equipment processing and manufacturing industry. In recent years, it has been widely used in metallurgy, military industry, aerospace, solar energy, industrial automation and other fields, and has gradually replaced some of the products of oil cylinder actuator,
pneumatic cylinder actuator and hydraulic cylinder actuator.
Through the understanding of the appeal, we know that the safety performance of the electrical linear actuator is in accordance with the norms, and believe that the electrical linear actuator will be better developed in the near future.
