The short version says Ball screws turn circular motion into a sliding one.
The Longer version says that Ball screws are a type of mechanical linear actuator that converts rotary motion into linear motion.
They are widely used in a variety of industrial and manufacturing applications, such as CNC machines, robotics, and assembly lines.
The basic-looking ball screw consists of a threaded shaft, which is paired with a nut that contains a set of recirculating ball bearings.
As the shaft rotates, the ball bearings move along the thread, causing the nut to move in a linear direction.
Ball screws by Tuli are widely known for their high efficiency.
This is possible due to the low friction between the ball bearings and the threaded shaft.
The low friction results in less heat generation, reduced wear and tear, and lower power consumption compared to other types of linear actuators. This makes ball screws an attractive choice for applications that require high precision, accuracy, and repeatability.
“Mechanical linear actuator” is a term used to describe a device that converts rotational motion into linear motion. In other words, ball screws are the most used mechanical linear actuators.
They provide high load-carrying capacity which is possible due to the contact between the recirculating ball bearings and the shaft.
The contact results in a larger contact area compared to other types of linear actuators, allowing ball screws to handle higher loads without compromising performance.
Ball screws are available in different lead configurations and sizes, allowing for greater design flexibility and customization. This means that ball screws can be tailored to specific applications, optimizing their performance and efficiency.
For example, the pitch of the ball screw can be adjusted to change the distance the nut moves for each rotation of the shaft, allowing for more precise control over the linear motion. The diameter of the shaft, the size and the number of ball bearings can also be customized to match the load requirements of the application.
Different types of ball screw designs are available to optimize performance for specific applications.
For example, high lead ball screws are designed for high-speed applications, while miniature ball screws are used in smaller, more precise applications.
Preloaded ball screws can reduce backlash and increase accuracy, while hollow ball screws can be used to transmit fluids or wiring.
By tailoring ball screws to specific applications, their performance and efficiency can be optimized, resulting in improved precision, accuracy, and speed. This allows manufacturers to improve the quality of their products and increase productivity.
