Mini Lead Screw Linear Actuator
Print Profile(1)
Bill of Materials
Description
This is a linear actuator model I designed specifically for 3D printing technology.
You can download it for free and use it for teaching and learning, or directly integrate it as a linear motion unit when designing other models.
Furthermore, you can also, as needed:
- Modify the slider into a fixture for clamping or securing parts
- Use it as a camera slider for smooth linear motion shooting
- Create a small automatic door or opening and closing mechanism
DIY an automatic feeder, and so on.
The applications are limited only by your imagination!- The motor uses an officially purchased DC TTmotor
- Screwless and metal-free, assembly can be completed with only 3D printed parts
- Assembly is quick, taking approximately 3 minutes
- Original model files use SolidWorks 2022
- Includes Chinese and English assembly instructions
- Feel free to ask questions and share insights in the comments
📐 The following are the basic parameters of this actuator:
⚙ Basic Parameters | Specifications
| Parameter | Value | Unit | Description |
|---|---|---|---|
| Motor | DC TT motor 59 RPM | - | Single-axis DC motor |
| Small Gear Teeth | 12 | - | Gear on the motor shaft |
| Large Gear Teeth | 24 | - | Gear driving the screw |
| Lead | 10 | mm | Distance the thread advances per revolution (single-start thread) |
| Total Travel | 144 | mm | Maximum distance the slider can move |
| Theoretical No-Load Speed | ≈ 4.9 | mm/s | Speed at which the slider advances per second |
| Theoretical Maximum Thrust | ≈ 3.77 | kg | Axial thrust calculated from theoretical torque |
Horizontal placement tests show it can move a 3KG object, and applying lubricating grease to the screw and slider limit may increase this further!
