1, first of all, according to the conditions of use and quality, speed, stroke, installation direction, positioning accuracy and other conditions to judge.
2. The specification of the pre-selected screw is to pre-select the precision grade, shaft diameter, pitch and length of the screw according to the use conditions.
Then what we need to do is to confirm the safety of the screw. Here, the maximum allowable axial load and maximum allowable rotational speed should be fully considered, and the rotational speed of the screw shaft should be confirmed to be within the maximum allowable range. Another point is the problem of life span, and it is necessary to determine the required life span.
4. Finally, according to the performance, if it is necessary to improve the positioning accuracy, it is necessary to determine the rigidity of the screw shaft, and at the same time, it is necessary to consider the life change of the screw itself caused by the temperature increase.
Therefore, the material selection of trapezoidal screw is also a very complicated and important link. Only by ensuring all the data can we produce the products that are most suitable for the customer's working environment. We always pay attention to product quality and service, and hope that we can bring you a better customer experience.
