How to choose a ball screw type linear module

The screw linear module is mainly composed of linear slides, ball screws, aluminum profiles, ball screw support points, motors, couplings, optical switches, and other components.

The screw linear module is mainly composed of linear slides, ball screws, aluminum profiles, ball screw support points, motors, couplings, optical switches, and other components.

The ball screw in the ball screw linear module is a commodity that converts rotational motion into uniform linear motion, or converts uniform linear motion into rotational motion. And ball screws are composed of extruder screws, nuts, and steel balls. Its function is to convert rotational motion into uniform linear motion. Due to its low frictional resistance, the ball screw type linear module can achieve uniform linear motion for precision machining under high load conditions. Therefore, it is widely used in various mechanical equipment and instruments.

When purchasing the model and specifications of the screw type linear module, the following aspects can be considered:

(1) What is the net weight of the load required for the screw linear module;

(2) Requirements for operating speed; Some companies require a linear module operating speed of 200mm/s, while some companies require a higher operating speed of 2000mm/s for their mechanical equipment to ensure normal operation.

(3) Requirements for motion accuracy. Motion accuracy generally refers to the repeated motion accuracy of the screw, that is, the distance between the ball screw linear module and the starting point when it returns to the end after reciprocating thirty times;

(4) Requirements for reasonable itinerary arrangement. What is the required distance in millimeters for moving from one end to the other;

In addition to purchasing a screw linear module based on its characteristics, it is also necessary to consider the requirements.

When purchasing a screw linear module, first determine the detailed main parameter requirements of the screw linear module based on the following aspects:

(1) When using modules in practice, it is required to load multiple objects and perform actual calculations. When the load exceeds 15KG, it is recommended to use the linear module of the ball screw transmission system.

(2) The actual module used requires a reasonable travel arrangement of about 50 millimeters more than the actual one, in order to pre embed the expansion of indoor space

(3) Modules with different main purposes have different requirements for motion accuracy.

In daily life, when purchasing a screw type linear module, one can choose a suitable, usable, and easy-to-use screw type linear module based on the common problems mentioned above, as well as their own purchasing requirements and main parameters.
