Frequently Asked Questions (FAQs)

1. What type of motion does a lead screw use?

A lead screw converts rotational motion into linear motion. It operates by sliding the screw shaft and the nut threads without the use of ball bearings.

2. What is the formula for linear force of a lead screw?

The formula for linear force of a lead screw is T = F1 x D/2. F1 represents the vector component of the force applied by the screw onto the ball bearing, and D is the distance per revolution specified by the lead, which determines the angle of the screw thread.

3. What is a lead screw linear actuator?

A lead screw linear actuator consists of a rotating nut inside a cylinder. The motor is constrained within the cylinder, while the nut moves to produce linear motion. These actuators are self-locking and have a minimal number of moving parts, making them compact and efficient.

4. What is the linear speed of a lead screw?

Under ideal conditions, a lead screw can accelerate at a rate of 20 m/s2. If higher accelerations are required, alternative drive train technologies like linear motors may be necessary, as they are capable of achieving 50 m/s2 or greater.

5. What is the difference between a linear motor and a ballscrew?

A linear motor and a ballscrew differ in terms of positioning feedback. While ballscrews use a rotary encoder for position feedback, linear motors use a magnetic or optical linear scale located at the load. This allows for a more accurate reading of the actual position.

6. How do you calculate linear force from screw torque?

To calculate linear force from screw torque, divide the screw torque by the product of the lever arm length and the sine of the angle of applied force.

7. Why are linear actuators so expensive?

Linear actuators can be relatively expensive due to several reasons. One factor is the need for high precision and accuracy, which requires high-quality materials and manufacturing processes. Additionally, the complexity of their design and the incorporation of precise positioning systems contribute to their cost.

8. What is the main advantage of a linear motor over a screw driven actuator?

The main advantages of a linear motor over a screw-driven actuator are speed and operational life. Linear motors can achieve outstanding acceleration rates, making them suitable for high-speed applications. They also have a longer lifespan due to the absence of gearing and reduced friction points.

9. What is the most efficient lead screw?

As a general rule, lead screws with higher helix angles tend to be more efficient. A higher helix angle reduces the energy required to overcome friction, resulting in improved efficiency. This is because a higher helix screw requires fewer rotations to achieve the same linear displacement compared to a lower helix screw.
