A micro screw is a smaller screw drive commonly used in applications requiring precise positioning and efficient transmission. It consists of a threaded screw and a steel ball running through it. The structure of the micro screw enables it to provide high rigidity and load capacity, as well as low friction losses and high efficiency.
There are several different types of micro screws depending on different parameters. Here are some common types of miniature screws:
1. Internal circulation support type micro screw: It has an internal circulation support mechanism, which can provide high rigidity and load capacity. Suitable for applications requiring high torque and higher precision.
2. External circulation support type micro screw: It has an external circulation support mechanism and provides a higher load capacity, but it is not as rigid as the internal circulation support type screw. Suitable for applications requiring high load capacity but low rigidity requirements.
3. High-speed micro screw: designed for high-speed transmission applications, with high transmission efficiency and low friction loss. Suitable for scenarios requiring fast movement and efficient transmission.
4. Micro screw without return mechanism: This type of micro screw has no return mechanism and can only perform one-way transmission. Suitable for applications requiring only one-way motion.
5. Light-load miniature screw: Suitable for applications with smaller loads, with smaller size and lower load capacity.
These are common types of micro screws. Depending on the specific application needs, a suitable micro screw can be selected to meet the requirements.
