How to select linear module quickly
Linear module, also known as electric cylinder and linear module in industry, is composed of the combination of linear module and motor drive. It can drive the workpiece to move automatically and linearly by motor drive. The combination of too many direction axes constitutes the motion actuator on the equipment, which is often called industrial manipulator, XYZ axis manipulator, coordinate axis slide, etc.
Linear modules are widely used in various industries, such as:
Entertainment industry: robot arms and joints, dynamic seats, etc.
Military industry: simulation aircraft, simulation and so on.
Automobile industry: press mounting machine, testing instrument, etc.
Industry: food machinery, ceramic machinery, welding machinery, spraying equipment, lifting platform, etc.
medical apparatus and instruments.
Transmission difference of linear module:
The ball screw drive means that the motor drives the ball screw to rotate through the coupling or synchronous pulley, and then pushes the slide block fixed on the linear guide rail forward and backward.
The ball screw has the characteristics of high positioning accuracy, small friction, high rigidity and strong load capacity. But to achieve precise positioning.
In terms of speed, it depends on the speed of the motor and the lead of the lead screw. The larger the lead of the lead screw is, the faster the slider of the single axis manipulator moves at the same motor output speed.
The synchronous toothed belt drive is driven by the motor to drive the driving wheel of the synchronous belt to rotate, and then the belt drives the straight line
The slide on the rail moves back and forth. The synchronous toothed belt has the characteristics of low noise, fast moving speed and low cost.
In terms of speed, it can generally achieve higher speed than ball screw. At the same time, there is no limit of critical speed, so it has more cost-effective in long-distance transmission. But the positioning accuracy of synchronous belt drive is lower than that of ball screw.
Knowing the advantages and disadvantages of two types of slide module, we can choose the appropriate module according to our own needs.
