Advantages of Linear Module

Reducing friction
The speed of a single object can be increased by quickly reducing friction. Linear modules can increase the speed of linear motion by reducing the friction between interacting objects. At the same time, the positioning speed of the linear module is also very fast, and the time consumption is greatly reduced. The increase in positioning speed and linear motion speed means that the positioning speed and linear motion speed can be changed, and more work can be completed in a short time, that is, the work efficiency is significantly improved. The belt linear module is particularly prominent in terms of speed advantages.

High repetitive positioning accuracy and fast
High repetitive positioning accuracy and fast positioning speed does not mean that it affects the positioning accuracy of the linear module. While increasing the speed, it further improves the positioning accuracy of the linear module. Repeated positioning can be accurate at the same time, without the need for re-calibration and multiple operations. The parts can avoid errors. The linear slide has a variety of models and specifications to choose from, which is convenient to use, and there is no need to correct itself and the product in the short term. Ball screw linear slide It occupies a strong advantage in repeated accuracy levels, and it is very common in the contemporary laser manufacturing industry and laser cutting manufacturing industry.

Small size and long life
Small size, long life, fast speed, and high precision are not all the advantages of linear modules, nor does it mean that linear modules are large in size. On the contrary, linear modules are smaller than existing transmission devices and are also used in precision equipment. Reason. For example, the service life of high-tech linear modules is basically more than 2000 (km).

How the Linear Module Works

The linear module is a set of equipment that is widely used in modern automation parts. Its names are also varied. Some are called linear modules, some are called electric cylinders, some are called slides, and some are called robotic arms. Although they are called The methods are different but their working principles are the same. It can be divided into synchronous belt drive and ball screw drive, but their working principles are the same. The linear module is a modular product designed to integrate the servo motor, screw and synchronous belt, converting the rotational motion of the servo motor into Linear motion, while transforming the best advantages of servo motors - precise speed control, precise revolution control, precise torque control into - precise speed control, precise position control, precise thrust control; to achieve high-precision linear motion, the following is a detailed introduction to synchronous belts and How ball screws work.

Working principle of synchronous belt linear module
The synchronous belt linear module is mainly composed of belts, linear guide rails, aluminum alloy profiles, couplings, motors, photoelectric switches, etc. The belt is installed on the drive shaft on both sides of the linear module, and the power input shaft is fixed on the belt to block the slider of the device. When input is used, the slider is driven by a belt. Usually the belt linear module has been specifically designed so that the tightness of the belt can be controlled on one side, which facilitates the debugging of the equipment during the production process. Synchronous belt linear modules can use rigid rails according to different loads to improve the rigidity of the linear module. Linear modules of different specifications have different load upper limits. The accuracy of timing belt linear modules depends on the combination of belt quality and machining process. Control of power input affects belt accuracy.

Working principle of ball screw linear module
It is mainly composed of ball screw, linear guide rail, aluminum alloy, ball screw pair, coupling, motor, photoelectric switch, etc. Ball screws are ideal products for converting rotary motion into linear motion or converting linear motion into rotary motion. Ball screws consist of screws, nuts and balls. It converts the function of rotary motion into linear motion. This is the further promotion and development of the ball screw. The important significance of its development is to transform the bearing from rolling motion to sliding motion. Ball screws are widely used in various industrial equipment and precision instruments due to their small friction resistance. High-precision linear motion can be achieved under high load conditions. These are the working principles of linear modules. Although it is very simple to say, the most important thing is high precision. This is also the biggest technical problem of domestic linear modules.

Load capacity
Straight modules usually need to have a certain amount of load, that is, how much weight the module needs to load. At present, many straight module manufacturers can provide products with a variety of loads. The factory must also select the linear module according to the actual weight of the load in the actual production process, otherwise it will cause insufficient linear module load and cause problems in the product line.

Stroke accuracy
Linear module manufacturers with sufficient supply will provide a lot of linear modules with different effective stroke specifications. Effective stroke refers to how long the interval between the movement of the linear module from one end to the other end is related to the fact that the factory can use the linear module The basic requirements on what products, the motion accuracy also requires the factory to choose according to the product, so the effective stroke motion accuracy is the factor that determines the specifications of the linear module when selecting the linear module manufacturer's product;

Configuration
The choice of linear module should also be from the perspective of configuration, such as the screw brand, guide rail, timing belt, switch, etc. of the selected brand specifications. The products of linear module manufacturers also have certain differences in configuration. Determine the configuration of the linear module according to the requirements for accuracy and other aspects when producing the product.
