The screw is a mechanical transmission element, which is widely used in various mechanical equipment. Its main function is to convert rotational motion into linear motion, or to convert linear motion into rotational motion. The types and uses of screw are very rich, let's introduce it below.
First, the type of screw
1. Ordinary lead screw: Ordinary lead screw is the most common kind of lead screw, and its thread shape is triangular, which is often used in some low-precision mechanical equipment.
Precision screw: The screw thread shape of the precision screw is trapezoid, the accuracy is higher than that of the ordinary screw, and it is often used in mechanical equipment that requires high precision.
3. Large lead screw: The diameter of the large lead screw is relatively large, and it is often used in mechanical equipment that needs to bear large loads.
4. Small lead screw: The diameter of the small lead screw is relatively small, often used in some small mechanical equipment.
5. Filament rod: The length of the filament rod is relatively long, and it is often used in mechanical equipment that requires long-term linear movement.
6. Short screw: The length of the short screw is relatively short, and it is often used in some small mechanical equipment.
7. Non-equidistant screw: The pitch of the non-equidistant screw is not fixed, and is often used in some mechanical equipment that needs to be changed.
Second, the use of the screw
1. Screw drive: Screw drive is one of the most common uses of screw, which can convert rotating motion into linear motion, or convert linear motion into rotational motion. Screw drive is widely used in a variety of mechanical equipment, such as lifts, shearing machines, injection molding machines and so on.
Adjustment: The screw can be used for the adjustment of mechanical equipment, such as adjusting the height of the workbench of the machine tool, adjusting the trajectory of the manipulator, etc.
3. Positioning: The screw can be used for positioning mechanical equipment, such as positioning the workbench of the machine tool, positioning the end actuator of the manipulator, etc.
4. Measurement: The screw can be used for the measurement of mechanical equipment, such as measuring the height of the workbench of the machine tool, measuring the movement trajectory of the manipulator, etc.
5. Support: The screw can be used for the support of mechanical equipment, such as supporting the workbench of the machine tool, supporting the end effector of the manipulator, etc.
6. Sensing: The screw can be used for sensing mechanical equipment, such as sensing the workbench height of the machine tool, sensing the movement trajectory of the manipulator, etc.
In short, the screw as a mechanical transmission element, its types and uses are very rich, can meet the needs of various mechanical equipment. In the future, with the continuous development of science and technology, the types and uses of screw will continue to expand and improve.
